The government recently imposed stock limits on tur and chana dals in order to prevent hoarding, speculation, and to improve affordability for consumers. This move comes as part of a series of measures taken to regulate the prices of essential commodities.

Imposition of Stock Limits:
The Centre has issued an order imposing stock limits on wholesalers, retailers, chain retailers, millers, and importers for tur and chana dals. These stock limits will be in effect until September 30, 2024. The aim is to prevent hoarding and ensure fair pricing for consumers.

Specific Limits:
Under the new order, specific stock limits have been prescribed for each category of entities. Wholesalers are allowed to stock up to 200 tonnes of tur and chana, while retailers can hold up to 5 tonnes at each outlet. Big chain retailers can stock up to 200 tonnes at their depot. Millers are allowed to hold the last 3 months of production or 25% of their annual installed capacity, whichever is higher.

Importers are also subject to restrictions, as they are not allowed to hold imported stock beyond 45 days from the date of customs clearance. Legal entities are required to declare their stock positions on the Department of Consumer Affairs portal. If stocks exceed the prescribed limits, they must bring them down by July 12, 2024.

Government’s Efforts:
The government has been taking proactive steps to monitor the stock positions of pulses through the stock disclosure portal. In addition to enforcing mandatory stock disclosures, officials have conducted visits to major pulses-producing states and trading hubs to ensure compliance.

Furthermore, the reduction of import duty on desi chana is expected to boost domestic production. This, along with increased sowing of Kharif pulses like tur and urad due to favorable monsoon predictions, is likely to bring down prices in the coming months.

Chimpanzees’ Medicinal Plant Use: Insights from Behavioural Observations and Pharmacological Testing

Shikher GoyalJune 23, 2024

First conclusive evidence that a terrestrial leech species can jump

Introduction:

Chimpanzees, our closest living relatives in the animal kingdom, have long fascinated scientists for their complex social behaviors and intelligence. A new study has shed light on another fascinating aspect of chimpanzee behavior – their ability to self-medicate using plants with medicinal properties. This study provides valuable insights into the evolutionary origins of medicine and healthcare practices in non-human primates.

Chimpanzees and Medicinal Plants:

The researchers conducted behavioral observations of wild chimpanzees in the Budongo Central Forest Reserve in Uganda, combined with pharmacological testing of the plants they consumed. They identified 13 species of trees and herbs that the chimpanzees were suspected of using for self-medication. The results were astonishing – 88% of the plant extracts tested showed antibacterial properties, while 33% had anti-inflammatory effects.

One striking example from the study involved a male chimpanzee with an injured hand. The researchers observed this individual seeking out and consuming leaves from a fern known as Christella parasitica. These leaves exhibited potent anti-inflammatory effects, which may have helped reduce pain and swelling in the injured hand. This observation suggests that chimpanzees have a remarkable ability to self-diagnose and treat their ailments using specific plants.

Case Study: East African Mahogany Tree

Among the plants tested, the researchers found that bark and resin from the East African mahogany tree (Khaya anthotheca) displayed strong anti-inflammatory properties. This finding is particularly interesting as it highlights the specificity with which chimpanzees select plants for medicinal purposes. By consuming parts of the mahogany tree, these primates may be alleviating inflammation and pain, much like humans would take anti-inflammatory medications.

Parasitic Infections and Medicinal Plants:

Another intriguing observation from the study involved a chimpanzee with a parasitic infection consuming bark from the cat-thorn tree (Scutia myrtina). This behavior suggests that chimpanzees may have the ability to self-medicate not only for physical injuries but also for internal ailments caused by parasites. The diverse range of medicinal plants consumed by chimpanzees points to a sophisticated understanding of the healing properties of different plant species.

Conclusion:

In conclusion, the findings of this study provide compelling evidence of chimpanzees using plants with medicinal properties to treat their ailments. This behavior underscores the complex cognitive abilities of these primates and offers valuable insights into the evolutionary origins of medical practices. By studying the self-medication behavior of chimpanzees, researchers can gain a deeper understanding of the relationship between animals and their environment. This study opens up new avenues for research on natural remedies and traditional healing practices in the animal kingdom.

The Medicinal Properties of Plants Consumed by Chimpanzees

Significance

The new study on chimpanzees consuming plants with medicinal properties sheds light on the sophisticated healthcare practices of these primates. By combining behavioural observations with pharmacological testing, researchers have demonstrated that chimpanzees have the ability to self-medicate using specific plant species. This discovery has implications for our understanding of animal cognition and could potentially inform conservation efforts for endangered primate species.

Features

The study involved monitoring the behaviour and health of 51 wild chimpanzees in Uganda’s Budongo Central Forest Reserve. Researchers collected plant extracts from 13 species of trees and herbs suspected to be used for self-medication by the chimpanzees. Pharmacological testing revealed that 88% of the plant extracts inhibited bacterial growth, and 33% had anti-inflammatory properties. Specific plant species, such as the East African mahogany tree and the fern Christella parasitica, exhibited potent anti-inflammatory effects.

Objectives

The objective of the study was to investigate whether wild chimpanzees actively seek out and consume plants with medicinal properties to treat their ailments. By combining behavioural observations with pharmacological testing, researchers aimed to identify specific plant species that may provide therapeutic benefits to the chimpanzees.

Effects

The results of the study suggest that chimpanzees have the capacity to select and consume specific plants for their medicinal effects. For example, one chimpanzee with an injured hand was observed seeking out and eating leaves of the fern, which may have helped reduce pain and swelling. Another individual with a parasitic infection consumed bark from the cat-thorn tree. These findings indicate that chimpanzees exhibit self-medication behaviours that parallel those observed in human societies.

Pros and Cons

One potential advantage of chimpanzees consuming plants with medicinal properties is that it may help them maintain their health and well-being in the wild. By self-medicating, chimpanzees could potentially alleviate symptoms of illnesses or injuries. However, there may also be risks associated with consuming certain plants, as not all natural remedies are safe or effective. Further research is needed to understand the full extent of the medicinal properties of plants consumed by chimpanzees.

The Wham-O Story: From Falcons to Frisbees and Hula-Hoops

Shikher GoyalJune 23, 2024

The Fascinating Story of Wham-O: The Makers of Hula-Hoop

When do you grow up? Is it when you become tall enough that you can reach the highest shelves, even fetching stuff for others in the household on occasions? Or, is it when you put on enough weight to be able to lug around things when needed? Or, are you considered grown up when you stop playing with toys?

There’s no one way to answer our initial question, really. But if we are going to take the final parameters suggested as our means to find out, then American inventors Arthur Melin and Richard Knerr never grew up! They surely did grow up, obviously. But they remained children at heart as they went on to spend a lifetime with toys.

Boyhood friends

Born within six months of each other (Melin was born on December 30, 1924, Knerr was born on June 30, 1925), Melin and Knerr were boyhood friends who went to the University of Southern California together. Breeding falcons was a hobby that they shared at this point, and training the falcons to dive was something that they relished.

They did this by lobbing meatballs at them on the wing, which they achieved using a home-made version of a slingshot as their projectile launcher. While they tried to sell their birds to enthusiasts without much luck, they got more traction for their launcher instead.

Wham-O is born!

As both of them weren’t too keen to join in their fathers’ businesses, they decided to make the most of the interest people showed in their slingshots. With a $7 down payment at Sears, Roebuck & Company, they purchased a power saw and set shop in Knerr’s parents’ Los Angeles garage. While Melin cut shots with the saw, Knerr sanded it and they were both involved in the business of selling it – first personally, and then through postal orders countrywide. The Wham-O Manufacturing Company was thus born in 1948.

They called it Wham-O for the sound a slingshot made when it hit its target. They expanded slowly, first moving out of the garage to a failed grocery store, before eventually becoming big enough to set up a factory. While they set out focussing on sporting goods, they flourished in the toys industry. They remained informal about their business throughout, even when they enjoyed tremendous success.

Frisbee frenzy

Their first major breakthrough came through a product that they bought in, the Frisbee. They came across Walter Frederick Morrison, who was trying to sell his flying discs in a parking lot in 1955. They bought the rights to what Morrison called Pluto Platters and got Ed Headrick, their research and development man at Wham-O, to add aerodynamic details like the rings on the top.

It wasn’t until 1958, when it was renamed Frisbee, that the product picked up in terms of sales. With slow and steady sales, it turned out to be one of the most popular toys from Wham-O’s stable, and it continues to remain relevant till this day. Just as Melin hoped, it has even formed the basis of a sport called Ultimate, which even has world championships now.

Hula-Hoop effect

Their biggest success, even if not financially, was the Hula-Hoop. According to company legend, the idea came to them when a visiting Australian told them about how they rotated a bamboo hoop around their waists as children in gym classes. Seeing its potential, they set about manufacturing what they called the Hula-Hoop using high-density polyethylene (HDPE), a plastic newly developed by the Phillips Petroleum Company.

An entire nation was taken by storm as Wham-O’s Hula Hoop and countless other imitations went off the shelves at an unbelievable rate. Wham-O sold anywhere between 20-40 million hoops in the first year alone (1958) and reached the 100 million mark – something unthinkable for most toys – by 1960. The fad, however, ended as quickly as it started as each household had two or three of these! Business inexperience and a mountain of plastic in the form of unsold hoops, meant that Wham-O didn’t make a killing from their Hula Hoop.

Bounce back like a Superball

They bounced back from that financial debacle with the Superball, 20 million of which they sold before dropping the product. It was made of compressed plastic called Zectron that bounced uncontrollably, something that a chemical engineer had accidentally come up with. It took them two years of development to overcome its tendency to fly apart and create the Superball.

For as long as they remained in business, Melin and Knerr kept tinkering and inventing. The patent for a water play toy filed by Melin on June 23, 1980 was probably among the last few toys that Melin and Knerr were involved with. Growing weary of business, Melin persuaded Knerr to sell the company in 1982, the same year when they received the patent for the water play toy.

Even though they had grown tired of business, they hadn’t grown tired of toys. Melin in particular kept up his interests in inventing and even patented a design for a two-handed tennis racket with an adjustable handle. After a lifetime of creating crazy stuff that they were able to sell world-over, Melin and Knerr died in the first decade of the 21st Century – Melin in 2002 and Knerr in 2008.

Brief Summary | UPSC – IAS

Arthur Melin and Richard Knerr, childhood friends and American inventors, founded the Wham-O Manufacturing Company in 1948. They started with slingshots before moving into toys, eventually creating popular products like the Frisbee and Hula-Hoop. The Hula-Hoop sold millions in its first year, but a market saturation led to financial troubles. They later found success with the Superball. Melin and Knerr continued inventing toys until they sold the company in 1982. They both passed away in the early 2000s, leaving behind a legacy of innovative and popular toys that captured the hearts of children worldwide.

The final joint communiqué signed by 82 countries and organisations called for an end to the conflict, highlighting the importance of sovereignty, territorial integrity, and adherence to international law.

Features

The summit focused on areas of broad understanding such as nuclear safety, food security, and the exchange of prisoners of war and displaced Ukrainians. However, the event was criticised for its one-sided approach in not inviting Russia and basing negotiations on the Ukraine Peace Formula and UN resolutions.

Objectives

The main objective of the summit was to bring together a diverse group of countries, particularly from the Global South, to work towards ending the conflict between Russia and Ukraine. The organisers aimed to create a platform for dialogue and collaboration to achieve peace and stability in the region.

Effects

The summit had mixed effects, with some countries hailing it as a historic victory while others criticized it for its shortcomings. The absence of key players like Russia and China, as well as the lack of endorsement from BRICS members, highlighted the challenges in achieving a comprehensive resolution to the conflict.

Pros

One of the pros of the summit was bringing together a large number of countries to discuss the conflict and work towards solutions. It also put the spotlight on important issues such as nuclear safety and food security, raising awareness on global challenges.

Cons

On the other hand, the summit was criticized for its exclusionary approach in not inviting Russia and failing to convince key players like China to participate. The outcome of the summit was seen as limited in its impact, particularly among emerging economies like BRICS members.

Brief Summary | UPSC – IAS

The “Summit on Peace” in Burgenstock brought together more than 90 countries, with 56 leaders present. The joint communiqué called for an end to the conflict between Russia and Ukraine and emphasized nuclear safety, food security, and the exchange of prisoners.

India’s Export Rebound Surges Despite Rising Imports

Shikher GoyalJune 23, 2024

Trade trapeze: The Hindu Editorial on India’s exports

Introduction:
India’s merchandise exports faced a challenging period in 2023-24, but there seems to be a shift in the trade dynamics with exports gaining momentum over the past few months.

Export Growth Recovery:
After a dip in exports in 2023-24, which saw a 3.1% decrease to around $437 billion, there has been a positive trend in outbound shipments. The growth in exports saw a significant upswing from a 1.1% rise in April to a 9.1% increase in May. This recovery started in the previous quarter, where exports grew by 4.9% to a seven-quarter high of over $120 billion. The reversal in fortunes is a positive sign for the Indian economy.

For example, 20 of India’s top 30 export items have outperformed last May’s export figures, indicating a broad-based recovery across key sectors. Sectors such as apparel, man-made yarn, and engineering goods have shown resilience by bouncing back in May. However, there are some concerns, as spice shipments declined by 20.3% and marine products faced another setback.

Import Challenges:
While exports have been on an upward trajectory, imports have also surged in recent months, leading to a widening trade deficit. In May, India’s import bill hit a seven-month high of $61.9 billion, resulting in a trade deficit of $23.8 billion, which is 25% higher than April’s gap. The record $13.2 billion deficit in petroleum products has been a significant contributor to this imbalance.

For instance, the rising deficit in petroleum products, coupled with the dependence on imports, has raised concerns about the sustainability of the trade balance. While oil prices have moderated since April, the import bill remains a critical factor that needs continuous monitoring.

Balancing Trade Imbalance:
To offset the trade deficit, Indian officials are relying on rising services exports and forex inflows from global investments. However, challenges remain as foreign direct investment inflows have decreased over the past years, and earnings guidance from IT services companies has not been optimistic. Enhancing efforts for import substitution and boosting goods exports are seen as crucial to address the imbalance.

An illustrative example would be the need for the Indian government to focus on revitalizing schemes and initiatives to bolster goods exports. Increased budgetary allocations and targeted policies are essential to stimulate export growth and reduce the reliance on imports.

Summary:
In conclusion, India’s export sector is showing signs of recovery after a challenging period in 2023-24. The recent momentum in outbound shipments, coupled with import challenges, underscores the need for strategic interventions to balance the trade dynamics. By focusing on key sectors, addressing import dependencies, and enhancing export promotion measures, India can navigate the global trade landscape more effectively. It is imperative for policymakers to prioritize initiatives that strengthen the export ecosystem and drive sustainable economic growth.

Additional Tips:

Use clear and concise language.
Ensure the article flows logically from one section to the next.
Incorporate relevant examples to illustrate key points.

Significance

India’s merchandise exports are showing signs of recovery after a decline, which is crucial for the country’s economy and trade balance.

Features

Recent months have seen an expansion in outbound shipments, with key sectors like apparel, man-made yarn, and engineering goods performing well.

Objectives

The objective is to boost exports, reduce trade deficit, and strengthen the country’s position in the global market.

Effects

The growth in exports can lead to increased revenue, job creation, and overall economic development. However, rising import bills and trade deficits can pose challenges.

Pros

Positive momentum in exports
Potential increase in revenue and job opportunities
Improved trade balance

Cons

Rising import bills and trade deficits
Challenges in import substitution and attracting foreign investments
Dependence on volatile global market conditions

Brief Summary | UPSC – IAS

India’s merchandise exports struggled in 2023-24, but are showing signs of recovery with a recent uptick in outbound shipments. Exports have been on the rise, fueled by a seven-quarter high in the January to March quarter. The European Central Bank cutting interest rates and the U.S. Federal Reserve scaling back expectations are seen as positive signs for exporters. However, rising commodity prices and a widening trade deficit, driven by high petroleum product imports, are concerns. Efforts are needed to boost exports in key sectors such as apparel and engineering goods, while also addressing issues causing declines in spice and marine product shipments.

BSP: A Hollow Shell of Its Past Due to Anodyne Political Stance

Shikher GoyalJune 23, 2024

Introduction:

The Bahujan Samaj Party (BSP) in India, once a formidable force in the political landscape, has seen a decline in its influence and power in recent years. The party, which was founded on the principles of social justice and empowerment of marginalized communities, has faced challenges that have eroded its support base and weakened its position in the political arena.

Subheading 1: Rise and Ideology of the BSP

The BSP was founded by Kanshi Ram in 1984 with the aim of representing the oppressed and marginalized communities, particularly the Dalits, in Indian politics. The party’s ideology centered around the idea of promoting social equality and empowerment of the Bahujan Samaj, which includes Scheduled Castes (SC), Scheduled Tribes (ST), and Other Backward Classes (OBCs).

For example, under the leadership of Mayawati, the BSP formed governments in Uttar Pradesh multiple times by attracting a substantial vote share from these communities. Their symbol, the elephant, became synonymous with the party’s commitment to uplift the oppressed.

Subheading 2: Decline in Relevance and Support

In recent years, the BSP has faced a decline in relevance and support due to various factors. One of the key reasons for this decline is the shift in the party’s focus towards power politics and alliances with other parties at the cost of its core ideology. This has led to disillusionment among its traditional support base, who feel that the party has deviated from its original mission.

For instance, the BSP’s decision to enter into alliances with parties that do not align with its ideology has led to a loss of credibility among its followers. This has resulted in a weakening of the party’s grassroots support and a decline in its electoral fortunes.

Subheading 3: Consequences of Anodyne Approach

The anodyne approach towards oppositional politics adopted by the BSP has made it a shell of its past self. The party’s reluctance to take a strong stance on key issues affecting marginalized communities has further alienated its supporters. This lack of clarity and conviction in its messaging has allowed other parties to hijack the narrative of social justice and claim it as their own.

For example, the failure of the BSP to effectively counter the narrative of other political parties on key social issues has resulted in a loss of identity and support among its target demographic. This has led to a decline in the BSP’s electoral performance and relegated it to the periphery of Indian politics.

Conclusion:

In conclusion, the BSP’s anodyne approach towards oppositional politics has had detrimental effects on the party’s relevance and influence. To reclaim its position as a champion of social justice and empowerment, the BSP must realign with its core ideology and take a more assertive stance on issues that matter to its supporters. Only by rediscovering its roots and re-engaging with its base can the BSP hope to regain its lost glory in the political arena.

By reflecting on its past successes and failures, the BSP can chart a new course that resonates with the aspirations of the Bahujan Samaj and re-establish itself as a force to be reckoned with in Indian politics.

Significance

The Bahujan Samaj Party (BSP) was founded with the aim of representing the interests of the Dalits, Adivasis, and other marginalized sections of society. Its significance lies in providing a platform for these communities to assert their political rights and challenge the dominant caste hierarchy in India.

Features

The BSP is known for its focus on the slogan of “Bahujan Samaj” (Majority Community) and its emphasis on social justice and equality. It has a strong presence in states like Uttar Pradesh and has played a significant role in coalition politics at the national level.

Objectives

The main objective of the BSP is to empower marginalized communities and provide them with a voice in the political process. It aims to challenge the entrenched power structures that have historically oppressed these communities and promote social equality.

Effects

However, in recent years, the BSP has been criticized for moving away from its original objectives and adopting a more anodyne approach towards oppositional politics. This has led to a decline in its influence and made it a shell of its past self.

Pros

Some argue that the BSP’s shift towards a more moderate stance may help it attract a wider range of supporters and improve its electoral prospects. It may also make it easier for the party to form alliances with other political parties.

Cons

On the other hand, this approach risks alienating the party’s core support base and diluting its original message of social justice and empowerment for marginalized communities. It may also weaken the party’s ability to effectively challenge the dominant political forces in the country.

Brief Summary | UPSC – IAS

The article discusses how the Bahujan Samaj Party (BSP) has experienced a decline in its political influence and power due to its mild approach towards opposing political parties. This lack of strong opposition has weakened the BSP and made it a mere shadow of its former self. The party’s failure to effectively challenge its rivals has hampered its ability to make significant gains in the political arena. Overall, the BSP’s passive stance towards opposition has led to its diminished status and reduced impact on the political landscape.

Chandru Committee has been tasked with addressing this issue and has made a series of recommendations to the State government.

Recommendations to Address Caste Identities

The committee has recommended that students be prohibited from wearing coloured wristbands, rings, or forehead marks that serve as caste identities. Additionally, students are advised to refrain from using bicycles that have any caste references painted on them. School names are also not to bear any caste appellation, and the caste confidentiality of pupils must be maintained.

For example, the government had previously dropped caste, community, and leader names from transport corporations and districts to address caste clashes in the past. This shows a historical precedent for addressing caste identities in public spaces.

The Role of Social Justice Monitoring Committee

The committee has recommended the establishment of a Social Justice Monitoring Committee comprising academicians and social activists. This committee would review curriculum related to social issues and suggest modifications to include topics on social justice, equality, and non-discrimination.

The suggestion to revise the syllabuses for B.Ed and Diploma in Elementary Education to promote inclusivity is another positive step recommended by the committee.

Concerns and Caution

While some recommendations are welcomed, there are concerns about others. The proposal to do away with noon meal kitchens in schools and establish centralised kitchens may mask the caste identity of cooks but may not address underlying discrimination. Depriving children of hot and fresh food from central kitchens could also present practical difficulties.

Additionally, the suggestion to establish a Social Justice Students Force operating independently of the union government raises concerns about the need for such a force when existing organizations like NCC, Scouts and Guides, and NSS already provide similar opportunities for students.

Addressing Caste Discrimination at the Grassroots Level

It is crucial for the government to address discrimination that begins at the village level, where caste-identifiable colors are prevalent in everyday surroundings. The prevalence of caste-based political outfits has only perpetuated caste divisions among schoolchildren, making efforts to establish harmony on campuses challenging.

Ultimately, there needs to be a transformation at the grassroots level and political will to transcend caste considerations in order to effectively address caste pride and discrimination among school students in Tamil Nadu.

Significance

The overt display of caste pride among schoolchildren in Tamil Nadu has resulted in violence and discrimination. The recommendations made by the Justice K. Chandru Committee aim to address this issue and promote harmony among students.

Features

– Prohibition of caste symbols such as coloured wristbands, rings, and forehead marks
– Removal of caste references from school names and bicycles
– Appointment of a Social Justice Monitoring Committee
– Revision of curriculum to include social justice topics
– Suggestions for inclusivity in teacher education syllabuses

Objectives

The objectives of the recommendations include promoting equality, eliminating caste discrimination, and fostering a harmonious environment for students in schools.

Effects

– Prevention of caste-based violence among schoolchildren
– Promotion of social justice and equality in education
– Establishment of a more inclusive and harmonious school environment
– Potential reduction in caste-related discrimination and conflicts

Pros

– Promotion of equality and inclusivity in education
– Prevention of caste-based discrimination and violence
– Establishment of a harmonious school environment for all students

Cons

– Practical difficulties in implementing some recommendations, such as centralised noon meal kitchens
– Potential challenges in establishing a uniformed Social Justice Students Force
– Resistance or backlash from groups or individuals who benefit from caste-based identities or discrimination

Brief Summary | UPSC – IAS

In Tamil Nadu, caste pride among schoolchildren has led to violence, prompting the Justice K. Chandru Committee to recommend banning caste identifiers like wristbands and tilakas. The committee also suggests changes to school names, curriculum, and the establishment of a Social Justice Monitoring Committee. However, the recommendation to centralized school kitchens is controversial, as it may not address discrimination. The proposal for a Social Justice Students Force and addressing discrimination in children’s environments is also debated. Ultimately, overcoming caste discrimination in schools requires political will and transformation at the village level to have a lasting impact.

Northern India Heatwave Crisis: Infrastructure Strain & Water Scarcity

Shikher GoyalJune 23, 2024

A torrid crisis: On heatwaves in northern India

As a teacher, it is important to educate our students about the current environmental issues that are affecting our country. The recent heatwave in Northern India is a serious problem that needs to be addressed by both the government and the citizens.

The article discusses how the temperatures in some states have been consistently above 45°C, which is unusual for this time of the year. The lack of moisture and rain has led to night temperatures being 3°-6°C above normal. This prolonged heatwave not only affects the daily life of people but also puts a strain on the infrastructure in the affected states.

The delay in the monsoon’s progress has only worsened the situation. The India Meteorological Department has updated its forecast to indicate that the rainfall in June will be below normal. This could lead to a water crisis in the region, as seen in Delhi where water pilferage is already a common issue.

The increased power demand in Northern India, as mentioned in the article, is another red flag. The fact that the region had to import power from other areas to meet its requirements shows a strain on the infrastructure. This strain is further exacerbated by the blackout at Delhi’s international airport and the water crisis in the region.

As teachers, we can use this information to educate our students about the importance of environmental conservation and the impact of climate change on our daily lives. We can also encourage them to take small steps in their daily lives to reduce their carbon footprint and help protect the environment. It is crucial for both the government and the citizens to come together to address the issues caused by the prolonged heatwave and take steps towards a sustainable future.

Significance

The ongoing heatwaves in Northern India have significant implications for the region’s infrastructure, energy demand, and water supply. The situation highlights the vulnerability of the region to extreme weather events and the need for coordinated efforts to address the challenges posed by climate change.

Features

The feature of the current heatwaves in Northern India include consistently high day and night temperatures, delayed monsoon onset, below-normal rainfall projections, increased energy demand, strain on power infrastructure, and water scarcity issues.

Objectives

The primary objective in light of the heatwaves is to address the immediate energy demand, ensure the stability of power supply, mitigate water scarcity, and take proactive measures to deal with the effects of climate change in the region.

Effects

The effects of the heatwaves in Northern India include increased strain on power infrastructure, potential grid failures, water scarcity, decreased agricultural productivity, and overall impact on public health and well-being.

Pros

Increased awareness about climate change, potential for collaboration between states and the center to address natural disasters, and opportunities for implementing sustainable solutions to mitigate the effects of extreme weather events.

Cons

Negative impact on agriculture, strain on power infrastructure leading to grid failures, water scarcity issues, potential public health concerns, and challenges in ensuring adequate energy supply to meet increasing demand.

Brief Summary | UPSC – IAS

Northern India is currently experiencing its longest stretch of heatwaves in 15 years. Temperatures have consistently been above normal, with minimum day temperatures reaching over 45° C and night temperatures 3°-6° C above normal. The monsoon has also been delayed and is expected to be below normal, leading to a strain on infrastructure and power supply. The Power Ministry reported a surge in demand, with northern India needing to import power from other regions. A water crisis is also looming, with Haryana refusing to increase supply to Delhi. The situation calls for a holistic approach to address the prolonged summer as a natural disaster.

Record High GST Revenues in April, Calls for Reform Agenda

Shikher GoyalJune 23, 2024

As a teacher, it is important to stay informed about current events and developments in the economy, including updates on the Goods and Services Tax (GST) in India. The recent news about GST revenues hitting a record high in April is significant and provides valuable insight into the country’s economic performance.

The increase in GST revenues to ₹2.1 lakh crore in April is a positive sign, indicating a higher compliance rate and increased economic activity. However, it is important to note that there was a slight slowdown in revenue growth in May compared to the previous month. This can be attributed to various factors, including the impact of the second wave of COVID-19 on economic activity.

Despite the overall growth in GST revenues, it is essential to focus on achieving a more simplified and efficient tax system. The upcoming GST Council meeting presents an opportunity to address key reform initiatives and enhance the effectiveness of the tax regime. One of the areas that require attention is the rationalization of GST rates to streamline the system and reduce complexities for businesses.

Additionally, efforts should be made to bring excluded items such as electricity, natural gas, and petroleum products into the GST net to ensure a more comprehensive tax structure. This will enable businesses to claim input credits and benefit from a more transparent and uniform tax system.

As a teacher, it is important to emphasize the significance of these reforms in ensuring a conducive business environment and promoting economic growth. By staying informed about developments in the GST regime and encouraging a dialogue on tax reforms, we can contribute to a better understanding of the tax system and its implications on businesses and the economy as a whole.

Significance

The Goods and Services Tax (GST) is a crucial source of revenue for the Indian government. It plays a significant role in the country’s fiscal management and has a direct impact on the economy.

Features

Some key features of the GST include a unified tax system, streamlined tax administration, and a simplified tax structure. It aims to reduce tax evasion and improve compliance.

Objectives

The main objectives of the GST are to create a common market by removing barriers to interstate trade, simplify the tax system, reduce tax cascading, and increase tax compliance.

Effects

The implementation of GST has led to increased tax revenues, improved tax compliance, and reduction in tax evasion. It has also brought transparency and efficiency to the tax system.

Pros

Some of the pros of GST include a broader tax base, simplified tax structure, reduced tax cascading, improved compliance, and ease of doing business.

Cons

On the flip side, some of the cons of GST include initial implementation challenges, compliance burden for businesses, multiple GST rates leading to confusion, and potential inflationary impact.

Brief Summary | UPSC – IAS

GST revenues hit a record high of ₹2.1 lakh crore in April, with May receipts at ₹1,72,739 crore. Revenue growth slowed in May compared to the previous month, but domestic revenue saw a 15.3% increase. However, revenues from goods imports dipped. The Council is meeting this Saturday to work on reform measures, including rationalizing the complex rate structure, bringing excluded items like electricity under GST, and easing compliance for all businesses. The Council must meet more regularly to address these issues and ensure the GST system becomes a truly Good and Simple Tax as originally intended.

Killer moonshine: On the hooch tragedy in Kallakurichi

The Importance of Good Governance in Preventing Tragedies like the Kallakurichi Hooch Deaths

Significance

Good governance plays a crucial role in maintaining law and order, ensuring public safety, and protecting citizens from preventable tragedies. The recent hooch deaths in Kallakurichi highlight the importance of proactive governance in anticipating and addressing potential hazards to public health.

Features

Effective governance involves not only maintaining routine operations but also identifying and addressing potential risks before they escalate into crises. In the case of the Kallakurichi hooch deaths, the failure to regulate the production and sale of illicit liquor led to a devastating loss of life.

Objectives

The main objective of good governance is to protect the well-being of citizens and prevent avoidable disasters. By enforcing regulations, monitoring suspicious activities, and educating the public about the dangers of consuming illicit alcohol, governments can reduce the risk of tragedies like the one in Kallakurichi.

Effects

The consequences of poor governance, as evidenced by the hooch deaths in Kallakurichi, can be tragic and far-reaching. Families are left devastated by the loss of loved ones, communities are shaken by the impact of preventable deaths, and public trust in authorities is eroded.

Pros and Cons

One of the advantages of good governance is the ability to prevent disasters and protect public safety. However, the failure to effectively enforce regulations and address warning signs can have deadly consequences, as seen in the case of the Kallakurichi hooch tragedy.

Fun Fact

Fun Fact: Methanol, commonly used to increase the strength of illicit alcohol, is a powerful poison that can cause severe health complications and even death in small quantities. Public awareness about the dangers of consuming hooch is crucial in preventing future tragedies.

Brief Summary | UPSC – IAS

In Kallakurichi, Tamil Nadu, a hooch tragedy has resulted in 39 deaths and many more hospitalized due to consumption of methanol-laced alcohol. The government has taken actions post-tragedy, including forming a committee and launching an investigation, but these steps may be deemed too little too late. The incident highlights the need for better governance, stricter enforcement against illicit alcohol production, and increased public health awareness about the dangers of consuming hooch. Despite past efforts to regulate alcohol production and distribution, the availability of cheap moonshine continues to pose a serious risk to public health and safety.

“Anthropocene Extinction: Human Impact on Biodiversity Loss”

Shikher GoyalJanuary 6, 2024

5 Incredible Facts about the Holocene Extinction

The Holocene extinction, often referred to as the Sixth Mass Extinction or Anthropocene Extinction, is an ongoing period of biodiversity loss marked by a significant decline in the diversity and abundance of various species on Earth. Unlike previous mass extinctions, the Holocene extinction is primarily driven by human activities, particularly habitat destruction, overexploitation of resources, pollution, climate change, and the introduction of invasive species.

The term “Holocene” refers to the current geological epoch, which began approximately 11,700 years ago and continues to the present day. The primary driver of the Holocene extinction is human activity, including the expansion of agriculture, urbanization, deforestation, industrialization, and other anthropogenic activities that have led to widespread habitat destruction and fragmentation.

One of the significant contributors to the Holocene extinction is unsustainable food production and consumption, which are significant contributors to greenhouse gas emissions that are causing atmospheric temperatures to rise, wreaking havoc across the globe. The climate crisis is causing everything from severe droughts to more frequent and intense storms, which makes it more difficult to maintain crops and produce sufficient food in some regions, thus affecting species’ habitats.

The intertwined relationships among the food system, climate change, and biodiversity loss are placing immense pressure on our planet. Currently, the species extinction rate is estimated between 1,000 and 10,000 times higher than natural extinction rates. The rate of species extinction is high enough to threaten important ecological functions that support human life on Earth, such as a stable climate, predictable regional precipitation patterns, and productive farmland and fisheries.

Efforts to curb the sixth mass extinction include ramping up commitments to cutting carbon emissions under global agreements like the Paris Agreement, the Kunming-Montreal Agreement, and de-extinction projects. De-extinction reverses plant and animal extinctions by creating new proxy versions of previously lost species, thus addressing the concern of losing crucial species from the ecosystem.

The Holocene extinction underscores the urgency of addressing human-induced threats to biodiversity and implementing effective conservation strategies to ensure the survival of diverse species and the health of ecosystems. It’s imperative to recognize the significance of the Holocene extinction and take action to mitigate its effects to protect the planet’s biodiversity and sustain life on Earth.

Potential of Tidal Energy in India: A Comprehensive Overview

Shikher GoyalNovember 10, 2023

Although it’s been debated for decades, the topic of tidal energy has dominated the headlines of late. What is it, what benefits does it offer and what’s the potential for its future use? Where does India’s Tidal energy potential lie? Read the article to know more about tidal power. India has a coastline of approximately 7,500 kilometers and experiences significant tidal variations, making it a potential candidate for harnessing tidal energy. While tidal energy is in its early stages of development in India, there have been efforts to explore its potential as a renewable energy source. The energy from nature- the sun, the wind, waves, tides, etc. can be converted into a usable form. We can make use of the energy from tides as a source of renewable energy.

What is Tidal Energy?

Tidal energy is produced by the gravitational interaction of the Earth, the sun, and the moon, which causes the tides to rise and fall naturally. Tidal waters can be used to make electricity by forming a reservoir or basin behind a barrage and then sending them through turbines in the barrier. Tidal energy is formed by the movement of tides and seas, and the intensity of the water from the rise and fall of waves is a type of kinetic energy. A tidal generator converts the energy of tidal flows into power. It is gravitational hydropower that creates electricity by using the movement of water to propel a turbine. Tidal power is a form of renewable energy that harnesses the kinetic and potential energy of ocean tides to generate electricity.

How does Tidal Energy generate power?

Tides are caused by the gravitational interactions between the Earth, the Moon, and the Sun, resulting in the rise and fall of water levels in oceans and seas. Tidal energy is generated by capturing the movement of water during these tidal cycles. Oceanic tides are used to generate electricity by building floodgate dams across sea/ocean inlets. During high tide, water flows into the inlet and is trapped when the gate is closed. The floodgate’s retained water is piped back to the sea. After the tide falls outside the floodgate, this water is sent via a turbine that generates electricity.

Methods of Harnessing Tidal Energy

There are two main methods of harnessing tidal power:

Tidal Stream Generator

Tidal stream generators, like wind turbines, utilize the kinetic energy of moving water to power turbines. These turbines are placed on the seabed in areas with strong tidal currents. As the tides flow in and out, the movement of water causes the turbines to rotate, generating electricity. Tidal stream systems can be installed in areas such as tidal channels, straits, and estuaries. Some tidal generators can be fitted into existing bridge constructions or be fully buried. High velocities can be generated at specific sites by land constrictions such as straits or inlets, which can be captured using turbines. Horizontal, vertical, open, and ducted turbines are all available.

Tidal Barrage

Tidal range systems like tidal barrages and tidal lagoons take advantage of the potential energy difference between high and low tides. Tidal barrages generate potential energy by utilizing the difference in height (or hydraulic head) between high and low tides. Tidal barrages are large dams or barriers built across the entrance of an estuary or bay. Sluice gates and turbines are used to control the flow of water through the barrage, allowing water to flow in during high tide and releasing it during low tide to generate electricity.

Tidal Lagoon

Tidal lagoons are similar to barrages but are constructed within a bay, creating an enclosed area with a tidal range. A modern tidal energy design idea is to build circular retaining walls outfitted with turbines that can catch the potential energy of tides. The reservoirs built are similar to tidal barrages, but the area is artificial and there is no pre-existing ecology.

Advantages of Tidal Energy

Tidal energy is a renewable resource, as tides are caused by the gravitational forces of the Moon and the Sun, which are predictable and consistent. As technology progresses, tidal energy will become more economical and efficient. These systems typically have lower environmental impacts compared to fossil fuel-based power generation. They do not produce greenhouse gas emissions or air pollutants. It defends against coastal floods because of its stability under varied design situations. Tidal lagoons can absorb storm surges and waves once every 500 years. Tidal power equipment and infrastructure have a significantly longer lifespan and are less expensive than other renewable technologies.

Limitations

The construction of tidal power facilities is now more expensive because of the significant capital needs. Tidal barrages can impact local ecosystems by altering water flow and sediment distribution. They can also affect fish migration patterns. The main environmental issues are the impacts of blades on fish seeking to enter the lagoon, auditory output from turbines, changes in sedimentation processes, and habitat alteration. Maintenance and repair of equipment can be complex. Energy demand is restricted. Powerful tides only occur on average for 10 hours per day, tidal energy storage capacity must be built. It is challenging to offer tidal energy to coastal areas since the energy of the tides is typically a long distance from where the electricity would be needed inland.

Tidal Energy Potential in India

India’s coastline has several locations with strong tidal currents and significant tidal ranges, particularly in the Gulf of Cambay (Khambhat) in Gujarat and the Gulf of Kutch. These areas have been identified as having the highest tidal energy potential in the country. The tidal cycle is caused by the moon’s gravitational influence and occurs every 12 hours. The difference in water height between low and high tide is referred to as “potential energy.” To capture enough power from the tidal energy potential, the high tide must be at least five meters (16 feet) higher than the low tide. Only around 20 areas on the earth get such high tides. India is one of them. On the west coast of Gujarat, the Gulf of Cambay and the Gulf of Kutch have maximum tidal ranges of 11m and 8m, respectively, with average tidal ranges of 6.77m and 5.23m. Research and development activities related to tidal energy are ongoing in various institutions and organizations in India. These activities focus on turbine design, deployment strategies, environmental impact assessments, and resource assessments.

Government Initiatives

India has collaborated with countries such as France and the United Kingdom to share knowledge and expertise in the field of tidal energy. These collaborations aim to accelerate technological advancements and project implementation. The Gujarat government inked an agreement in 2011 with Gujarat Power Corporation Limited (GPCL), Atlantis Resource Corporation (UK), and Power Monitoring Expert Systems, Singapore to build a 250 MW tidal power plant in the Gulf of Kutch. The first phase of a 50 MW tidal power plant in Mandavi in the Kutch area has commenced. The Ministry of New and Renewable Energy (MNRE) sanctioned a demonstration project in 2008 to develop a 3.75 MW tidal power plant in Durgaduani Creek in the Sunderbans of West Bengal, but it never saw the light of day.

Challenges

It’s been only 40 years since India began attempts to study and harness tidal energy. A legislative commission has now asked the Indian government to reconsider the potential of tidal power in India. It also asked to explore the realistically exploitable potential, do additional research in the sector…

Fun Fact

India is one of only around 20 areas on Earth that experiences high tides of at least 5 meters (16 feet) higher than low tide.

In conclusion, tidal energy holds great potential for India, a country with a vast coastline and significant tidal variations. The development of tidal energy projects can contribute to the country’s goals of achieving energy security and reducing carbon emissions. While there are challenges to overcome, ongoing research and government initiatives provide hope for the future of tidal energy in India.

Significance of India and Bhutan’s Infrastructure and Connectivity Initiative

Shikher GoyalNovember 10, 2023November 8, 2023

Closer together: The Hindu Editorial on the India-Bhutan talks and the plans ahead

The decision by India and Bhutan to focus on infrastructure and connectivity during talks between Prime Minister Narendra Modi and Bhutan’s fifth King Jigme Khesar Namgyel Wangchuck is an important marker towards more bilaterally driven regional initiatives. The joint statement speaks of completing surveys for the Kokrajhar-Gelephu rail link that connects Bhutan to Assam, and beginning discussions on another Bhutan to West Bengal rail link, while also facilitating Bhutan-Bangladesh trade, with yet another rail link, and upgrading checkpoints along the India-Bhutan border. These plans foretell a future that could well change the development story of the region, including West Bengal and the northeast, Bhutan’s south and east dzongkhags (districts), as well as Northern Bangladesh.

Key Features and Objectives

Bhutan’s economy has been dependent on hydropower and tourism revenues and has been hit by the COVID-19 pandemic and worries over global warming. A lack of opportunities has also led to emigration by educated youth and professionals. The new project proposed by the King, to build a Special Economic Zone at Bhutan’s southern border with Assam, and an airport at Gelephu, are expected to drive growth and investment in the kingdom. In addition, the signing of a Preferential Trade Agreement with Bhutan in 2020 could increase Bhutanese exports of local produce and build more markets for Indian and Bangladeshi producers in the sub-region.

Effects of the Initiative

India’s “energy exchange”, which is bringing more Bhutanese and Nepali hydropower suppliers online, while planning to distribute energy to Bangladesh and Sri Lanka, will drive intra-regional growth and revenues. This would also power New Delhi’s attempt at bridging the economic gap with the northeast, while drawing development partners like the World Bank and donor countries like Japan into the creation of a “sub-regional hub”.

Pros and Cons

Efficient and time-bound execution is key to such ambitious plans. Given India’s problems with Pakistan and sanctions on Myanmar for the 2021 coup blocking the path for trade and land connectivity to the East, working with other countries on India’s periphery to build connectivity, markets, and energy links is the most sustainable way forward. In the longer term, geopolitical conflicts and anti-globalization trends are forcing regional groupings to be more cohesive, something South Asia has not been able to achieve as yet. As India worries about China’s push into South Asian trade, infrastructure projects, and strategic ties, including concerns over a Bhutan-China boundary agreement’s overhang over Doklam and India’s “Chicken Neck” (Siliguri Corridor) route, these are ideas which will offer more security and prosperity for the countries involved, with particular benefits for Bhutan, India’s traditionally trusted partner in the region.

Fun Fact

India and Bhutan’s collaboration on infrastructure and connectivity not only improves the economic prospects of the region but also strengthens bilateral ties and regional stability, making it a significant step towards greater prosperity and security.

Brief Summary | UPSC – IAS

India and Bhutan are focusing on infrastructure and connectivity to drive bilateral regional initiatives. Plans include a rail link between Bhutan and Assam, discussions for another rail link to West Bengal, and facilitating trade with Bangladesh. Bhutan’s economy has been hit by the pandemic and global warming, and the new projects aim to drive growth and investment. India’s “energy exchange” and Bangladesh’s trade agreement with Bhutan will also contribute to regional growth. These plans will help bridge the economic gap with the northeast and create a “sub-regional hub.” Efficient execution is key, and working with neighboring countries is seen as the most sustainable way forward given geopolitical conflicts and anti-globalization trends. This collaboration will also offer more security and prosperity for the countries involved, with particular benefits for Bhutan.

Ecology, derived from the Greek word “oikos” meaning “house” or “place to live,” is the study of the relationships between living organisms and their physical environment. It explores the vital connections between plants, animals, and the world around them. The field of ecology provides essential information about the benefits of ecosystems and how we can utilize Earth’s resources in a sustainable manner for future generations. Let’s delve deeper into this fascinating science.

What does the term “ecology” imply?

The term “ecology” was coined by the German zoologist, Ernst Haeckel, in 1866. However, ancient Indian texts also contain references to ecological principles, such as the Vedas, the Samhitas, the Brahmanas, and the Aranyakas-Upanishads. These texts recognized the importance of ecological concepts, showcasing the deep roots of ecological understanding in human history.

What are the components of ecology?

Ecology primarily involves the study of biotic and abiotic factors within the environment. Biotic components encompass living factors of an ecosystem, including bacteria, animals, birds, fungi, and plants. On the other hand, abiotic components encompass non-living chemical and physical factors, such as sunlight, soil, air, moisture, and minerals. Understanding the interactions between these components is crucial for comprehending ecological processes.

How many Levels of Organisation are there?

Ecology encompasses several levels of organization, which are natural systems described by part-whole relationships. These levels, from smallest to largest, include:

1. Organism/Individual

The organism is the basic level at which living beings function independently. They possess characteristics such as response to stimuli, reproduction, growth, adaptation, and maintaining equilibrium. Dogs, cats, plants, fungi, bacteria, and archaea are all examples of organisms.

2. Population

A population refers to a group of individuals of the same species living in a specific geographic area at a given time. Here, attention is given to population size, density, structure, migration patterns, and interactions among individuals of the same population.

3. Community

A community comprises populations of different species that coexist in a specific area. It represents the interactions and relationships between species within an ecosystem. Communities are named after the dominant plant species present, and they are made up of all the biotic components in an area.

4. Ecosystem

An ecosystem includes a community of living organisms (biotic) interacting with the environment (abiotic). It represents the flows of nutrients and energy within a given area. Ecosystems are essential for understanding the intricate relationships between different organisms and their environment.

5. Biome

A biome refers to a set of ecosystems sharing similar characteristics, including climate, flora, fauna, and soil type. Each biome is adapted to its specific environment, shaping the distribution and abundance of plant and animal life within it.

6. Biosphere

The biosphere encompasses all the biomes on Earth and includes the sum of all living organisms and their surroundings. It refers to the portion of the planet that sustains life, covering the Earth’s surface, oceans, and atmosphere. The biosphere highlights the interconnectedness of all living beings and their habitats.

What are the principles of ecology?

Ecology relies on several principles to understand the functioning of ecosystems. These principles include:

Interdependence: All living organisms depend on one another and their environment for survival.
Succession: Ecosystems undergo predictable changes over time, transitioning through stages of growth, development, and decline.
Biodiversity: The variety of life within an ecosystem is essential for its stability and resilience.
Energy flow: Energy flows through ecosystems, starting with primary producers (usually plants) and moving through different trophic levels.
Nutrient cycling: Nutrients are recycled within an ecosystem, moving between living organisms and the abiotic environment.
Limiting factors: Certain factors, such as the availability of resources or the presence of predators, limit the growth and population sizes of organisms in an ecosystem.

Effects and Significance of Ecology

Ecology plays a crucial role in understanding and mitigating the environmental impacts of human activities. It helps in the conservation of endangered species and habitats by identifying ecological factors leading to their decline. Additionally, ecology provides insights into sustainable resource management and promotes environmental awareness and stewardship.

Pros of Ecology

Enhanced understanding of ecosystems and their interconnections
Identification of environmental issues and potential solutions
Promotion of sustainable practices for resource utilization
Conservation of biodiversity and protection of endangered species
Facilitation of informed decision-making for policies and regulations

Cons of Ecology

Complexity of ecological systems makes it challenging to study and predict outcomes accurately
Resource-intensive research and data collection methods
Resistance to change and adoption of sustainable practices

Fun Fact

Did you know that ecological concepts can be found in ancient texts? The Vedas, ancient Indian texts dating back thousands of years, contain references to ecological principles. This shows that humans have been observing and interacting with their environment in a sustainable manner since ancient times.

Ecology encompasses various branches, principles, and levels of organization. It provides a holistic understanding of the complex interplay between living organisms and their environment.

Vulture Conservation in India: Protecting and Reviving Declining Populations | UPSC – IAS

Shikher GoyalNovember 7, 2023

Vulture conservation in India is a crucial effort aimed at protecting and reviving the declining populations of vultures in the country. The population decline was noticed in the 1990s, and since then numerous efforts have been made to reclaim the vulture population.

Significance of Vulture Conservation | UPSC – IAS

Vultures play a significant role in maintaining ecological balance by scavenging and consuming animal carcasses, thereby preventing the spread of diseases and maintaining the cleanliness of the environment. Vultures, also known as condors, are large birds of prey with over 20 species in the world.

Reasons for Vulture Population Decline | UPSC – IAS

The vulture population decline is a significant conservation concern that has been observed in various regions around the world, including India. The primary reasons for the vulture population decline in India are as follows:

Diclofenac Poisoning: The widespread use of the veterinary drug diclofenac in livestock led to the sharp decline of vulture populations in South Asia. When vultures feed on carcasses of animals that were treated with diclofenac, they suffer from severe kidney failure and die.
Secondary Poisoning: Vultures are also affected by secondary poisoning when they consume the carcasses of animals that were poisoned by pesticides or other toxic substances.
Habitat Loss: The loss of natural habitats due to urbanization, deforestation, and agricultural expansion has negatively impacted vultures. Destruction of nesting sites, roosting areas, and food sources reduces the availability of suitable habitats for vultures.
Collisions with Buildings: Vultures are susceptible to collisions with power lines, wind turbines, and other infrastructure, leading to injuries or fatalities.
Poaching and Hunting: In some regions, vultures have been deliberately targeted and killed due to superstitions, traditional beliefs, or for use in illegal wildlife trade.
Lead Poisoning: Vultures may be exposed to lead poisoning by consuming carcasses of animals that were hunted using lead ammunition.
Disease Outbreaks: Outbreaks of diseases such as avian pox and avian flu have also had adverse effects on vulture populations.

Vulture Conservation Measures in India | UPSC – IAS

To address the vulture decline and conserve these important birds, several conservation initiatives and strategies have been implemented in India, including:

Vulture Safe Zones: Identifying and designating vulture safe zones, where the use of diclofenac and other harmful veterinary drugs is banned, to provide safe feeding areas for vultures.
Ban on Diclofenac: The government of India took measures to ban the veterinary use of diclofenac to prevent its consumption by livestock.
Vulture Conservation Breeding Centers: Establishing vulture conservation breeding centers to breed and rear vultures in captivity, releasing them back into the wild to augment wild populations.
Vulture Restaurants: Creating vulture restaurants where safe food is provided to vultures to supplement their diet and ensure their survival.
Rescue and Rehabilitation: Setting up facilities for the rescue, rehabilitation, and treatment of injured or sick vultures.
Research and Monitoring: Conducting research and monitoring programs to study vulture populations, behavior, and ecological requirements.
Public Awareness Campaigns: Educating and raising awareness among the public, farmers, veterinarians, and other stakeholders about the importance of vultures and the threats they face.
Collaboration: Collaborating with international organizations and experts to share knowledge, expertise, and best practices in vulture conservation.

Successes and Challenges | UPSC – IAS

As a result of these conservation efforts, there has been some success in stabilizing vulture populations in certain regions of India. The banning of diclofenac and the establishment of vulture conservation breeding centers have been particularly effective. However, continuous efforts are needed to ensure the long-term survival and recovery of vulture species.

While the conservation measures have been largely successful, there are some challenges that need to be addressed. These include the ongoing threat of habitat loss, collisions with infrastructure, and poaching. Public awareness and involvement are crucial in overcoming these challenges and ensuring the success of vulture conservation in India.

Fun Fact

The first instance of captive breeding of the Himalayan vulture (Gyps himalayensis) in India was recorded at the Assam State Zoo, Guwahati. This milestone highlights the progress made in vulture conservation efforts in the country.

The Government’s Revised Crop Residue Management Guidelines: A Step towards Efficient Ex-Situ Management

The government has recently revised the crop residue management guidelines, with a focus on enabling efficient ex-situ management of paddy straw. This move comes as the benefits of crop residue management and adverse effects of residue burning on soil quality are being given due attention. The revised criteria for crop residue management will be implemented in Punjab, Haryana, Uttar Pradesh, and Delhi, where paddy straw is primarily produced.

Significance of Crop Residue Management

Crop residue management plays a crucial role in agricultural practices. Harvesting various crops generates a large volume of residues both on and off-farm. The Ministry of New and Renewable Energy estimates that around 500 million tonnes of crop residues are generated annually. These residues have various uses, such as livestock feed, bio-gas generation, composting, biomass energy production, and fuel for domestic and industrial use. However, a significant portion of crop residues is burnt ‘on-farm’, primarily to clean the field for sowing the next crop.

The problem of on-farm burning of crop residues has intensified in recent years due to a shortage of labor, high removal costs, and mechanized harvesting. This practice is particularly prevalent in Haryana, Punjab, Uttar Pradesh, and West Bengal. The National Green Tribunal has already directed and prohibited agricultural residue burning in certain areas. Paddy stubble burning, in particular, is a common practice in the Indo-Gangetic plains of Punjab, Haryana, and Uttar Pradesh.

Features of In-Situ Crop Residue Management

In-situ crop residue management involves leaving the crop residue in its natural state on the field, without removal. This practice helps maintain soil health and fertility while reducing the risk of pests and diseases. There are several techniques used for in-situ crop residue management:

1. Mulching:

Mulching entails leaving crop residue on the soil surface to protect it from erosion and retain moisture. It also suppresses weeds and provides nutrients to the soil.

2. No-till farming:

In this method, crops are planted without disturbing the soil. Crop residue is left on the surface, and seeds are planted through it. No-till farming helps conserve soil moisture, reduce erosion, and improve soil quality.

3. Strip-till farming:

This method is similar to no-till farming but involves tilling only a narrow strip of soil where seeds will be planted. Crop residue is left on the soil surface between the tilled strips, providing a suitable environment for seed germination while conserving soil moisture and reducing erosion.

4. Cover crops:

Cover crops are planted between cash crops to provide ground cover and add nutrients to the soil. They can also be left on the soil surface as mulch.

5. Crop rotation:

Alternating the type of crops grown on a field each season can help reduce erosion, nutrient depletion, and improve soil health.

Features of Ex-Situ Crop Residue Management

Ex-situ crop residue management involves removing agricultural waste from the field for various uses such as composting, animal feed, and industrial processes. This method provides a natural source of nutrients for the soil and helps reduce air pollution caused by burning residue. Some ex-situ crop residue management techniques include:

1. Biomass power generation:

Crop residues can be used as a source of fuel for biomass power generation. By burning crop residues, electricity or heat can be produced.

2. Animal feed:

Crop residues can serve as a source of animal feed, especially for livestock like cattle, sheep, and goats. The residues can be stored and used as feed during dry seasons when forage is scarce.

3. Composting:

Crop residues can be composted along with other organic materials like manure, leaves, and grass clippings to produce a nutrient-rich soil amendment. This improves soil fertility and structure.

4. Biochar production:

Biochar, a type of charcoal, can be produced by heating crop residues in the absence of oxygen. It can be used as a soil amendment to enhance fertility, water retention, and crop productivity.

5. Industrial uses:

Crop residues can be utilized in various industrial processes, including paper production, textiles, and building materials.

Effects of Crop Residue Burning

Burning crop residues has several adverse effects on soil quality and the environment:

1. Loss of nutrients:

When crop residues are burned, essential nutrients like nitrogen, phosphorus, potassium, and sulfur are lost. The burning of one tonne of rice straw, for example, leads to the loss of approximately 5.5 kg of nitrogen, 2.3 kg of phosphorus, 25 kg of potassium, and 1.2 kg of sulfur.

2. Impact on soil properties:

The heat from burning residues raises soil temperature, leading to the death of beneficial soil organisms. Frequent residue burning can result in a complete loss of microbial population and reduction in nitrogen and carbon levels in the topsoil, which are crucial for crop root development.

3. Emission of greenhouse gases:

Crop residue burning is a significant source of greenhouse gases, such as methane, carbon monoxide, nitrous oxide, and other hydrocarbons. These emissions contribute to climate change and air pollution.

Updated Crop Residue Management Guidelines

The government’s updated crop residue management guidelines include the following provisions:

1. Bilateral agreements:

Beneficiaries/aggregators, such as farmers, rural entrepreneurs, cooperative societies of farmers, farmer producer organizations (FPOs), and panchayats, will enter into bilateral agreements with enterprises that utilize paddy straw. These agreements will form the basis for techno-commercial pilot projects for the supply chain of paddy straw.

2. Financial assistance:

The government will provide financial assistance for the capital cost of machinery and equipment required for crop residue management. The working capital can be financed jointly by the industry and the beneficiary or through sources like the Agricultural Infrastructure Fund (AIF), NABARD Financial, or financing from financial institutions.

3. Storage and preparation of paddy straw:

The beneficiary will arrange and prepare the land for the storage of collected paddy straw as guided by the end-use industry.

4. Project proposal-based assistance:

Financial assistance will be provided for the establishment of a paddy straw supply chain, including machines and equipment like tractors, cutters, balers, loaders, and telehandlers. State governments will approve these projects through a project sanctioning committee.

5. Financial support breakdown:

The government will provide 65% of the project cost, while the industry will contribute 25% and act as the primary consumer of the feedstock. The remaining 10% will be contributed by farmers, rural entrepreneurs, cooperative societies, FPOs, or panchayats who directly benefit from the project.

Effects and Outcomes

The implementation of the revised guidelines is expected to have several positive effects:

– The initiative will supplement in-situ crop residue management options.
– Approximately 1.5 million metric tonnes of surplus paddy straw, which would have otherwise been burnt in fields, will be collected over three years.
– About 333 biomass collection depots will be built in states like Punjab, Haryana, Uttar Pradesh, and Madhya Pradesh.
– Air pollution caused by crop residue burning will be significantly reduced.
– The initiative will create employment opportunities, equivalent to approximately 9,00,000-man days.
– It will encourage the establishment of a robust supply chain for paddy straw, allowing its use in power generation, heat generation, bio-CNG, and other applications.
– The establishment of the supply chain will attract new investments.

Fun Fact: Did you know?

Crop residues, especially rice straw, have been traditionally used in many countries to make rice paper, a thin and translucent kind of paper used for writing, artwork, and lantern making.
