GS Paper: GS3

  • Cash Transfers vs Foodgrain Distribution

    Central idea

    • Three years ago, financial constraints prevented the Centre and states from providing cash transfers to vulnerable households during pandemic lockdowns. However, there was an abundance of wheat and rice in FCI’s warehouses, allowing distribution to 813.5 million people. However, the current scenario has reversed, with governments having funds but limited grain stocks, raising concerns for future provisions.

    Grain Distribution and Export Scenario

    Grain Distribution:

    • During the pandemic-enforced lockdowns the government distributed 10 kg of grain per month practically free to 813.5 million people from April 2020 to December 2022.
    • This distribution was made possible through the public distribution system (PDS) and aimed to support poor and vulnerable households suffering from job and income losses.

    Offtake of Grains:

    • 2020-21 (April-March): The offtake of wheat and rice totalled 92.9 million tonnes, surpassing the annual average of 62.5 million tonnes during the first seven years after the National Food Security Act (NFSA) implementation.
    • 2021-22: The offtake further increased to 105.6 million tonnes.
    • 2022-23: The offtake remained high at 92.7 million tonnes.

    Grain Exports:

    • Rice: In 2021-22, India exported 21.2 million tonnes of rice, valued at $9.66 billion. In 2022-23, rice exports reached 22.3 million tonnes, valued at $11.14 billion.
    • Wheat: Wheat exports accounted for 7.2 million tonnes ($2.12 billion) in 2021-22 and 4.7 million tonnes ($1.52 billion) in 2022-23

    Karnataka Case: Shift from Grain to Cash Transfers

    • Change in Financial Situation: As economic activities resumed, the financial situation improved for both the Centre and the states. Gross GST revenues grew, indicating increased financial resources available to the governments.
    • Reduction in Grain Quota: From January 2023, the monthly grain quota under the National Food Security Act (NFSA) was reduced from 10 kg to 5 kg per person.
    • Additional grain demand: The government in Karnataka sought additional grain from the FCI to fulfill its election promise of providing 10 kg of free rice per month to all members of below-poverty-line (BPL) households.
    • Centre’s Refusal: The Centre did not allow the state government to distribute the extra rice beyond the 5 kg provided under the National Food Security Act (NFSA)
    • Resort to Cash Transfers: As a result the Karnataka government started giving cash transfers instead. They started transferring Rs 170 to the bank accounts of the BPL family heads in lieu of the extra 5 kg of rice

    Implications of cash transfers 

    • Inflationary Pressures:
    • When households receive cash instead of free grain, they have the flexibility to use the money for various purposes, including purchasing rice or other goods.
    • Increased demand for rice in the market can lead to higher prices, potentially contributing to inflationary pressures.
    • Deflationary Impact of Free Grain Distribution:
    • When surplus grains are distributed without a monetary transaction, it can help stabilize or reduce the prices of grains in the market.
    • This can mitigate inflationary pressures and ensure affordable access to essential food items for vulnerable populations.
    • Budgetary Considerations:
    • This allocation needs to be carefully managed to ensure that it aligns with overall fiscal goals and priorities.
    • The availability of adequate financial resources for cash transfers can be a determining factor in choosing between cash transfers and free grain distribution.
    • Flexibility for Beneficiaries:
    • Instead of receiving a predetermined amount of grain, households can decide how to allocate the cash according to their priorities.
    • This flexibility allows households to address their unique requirements beyond food, such as healthcare, education, or other essential expenses.
    • Market Dynamics:
    • Cash transfers can stimulate economic activity by injecting money into local markets. This can have positive multiplier effects, benefiting various sectors and local businesses.
    • On the other hand, free grain distribution may limit the market demand for grains, potentially affecting the livelihoods of farmers and traders.

    Depleted grain stocks and uncertain monsoon

    • Depleted Grain Stocks:
    • The total stocks of wheat and rice in the Central pool today stands at a five-year-low.
    • While these stocks are still above the normative minimum required, there are concerns about the monsoon and its impact on this year’s rice crop, which may affect procurement and future stocks.
    • Monsoon Impact on Production:
    • The poorly distributed rain has resulted in lower-than-usual rice cultivation, with farmers having planted only 123.18 lakh hectares out of the normal total of 399.45 lakh hectares under rice during the monsoon season. Additionally, the cumulative area sown is 6.1% lower than the previous year.
    • Insufficient rainfall in the monsoon’s second half can impact not only the kharif rice but also the upcoming rabi wheat crop.

    The Export conundrum

    • Record Export Quantities: Despite the imposition of restrictions on grain exports, India witnessed record-breaking exports of rice, wheat, and other cereals. Specifically, total exports amounted to 32.3 million tonnes in 2021-22 and 30.7 million tonnes in 2022-23, valued at $12.87 billion and $13.86 billion, respectively.
    • Inflationary Pressures:  The rising demand for rice, coupled with reduced domestic availability due to exports, can lead to higher prices for consumers within the country.
    • Limited Import Capability for Rice: As India is the world’s largest rice exporter, importing rice in case of domestic production shortfalls becomes challenging. Unlike wheat, which can be imported due to ample global supplies, rice imports are restricted.
    • Price Volatility and Potential Export Restrictions: The rising rice prices globally, indicating potential price volatility. Given concerns over depleted grain stocks and uncertainties related to the monsoon, the government is considering additional export restrictions.

    Way forward: A balanced approach

    • Targeted Cash Transfers: Implement focused cash transfer programs to support the most vulnerable households affected by economic hardships.
    • Optimal Grain Procurement: Strengthen grain procurement mechanisms to ensure an adequate supply of grains for the Public Distribution System (PDS) and strategic reserves.
    • Strategic Stock Management: Develop effective strategies to balance grain distribution for immediate consumption while maintaining sufficient reserves for emergencies.
    • Diversify Food Sources: Explore diverse food options, such as millets, pulses, and vegetables, to reduce reliance on a single crop and enhance food and nutritional diversity.
    • Enhance Food System Resilience: Improve supply chain efficiency, reduce food waste, and enhance coordination among stakeholders for a resilient food system.
    • Continuous Monitoring and Evaluation: Establish robust monitoring and evaluation systems to track the effectiveness of cash transfer programs, grain procurement strategies, and food security initiatives.

    Conclusion

    • The current state of depleted grain stocks, coupled with the uncertainties surrounding monsoon performance and global market dynamics, presents a significant challenge for the government. Balancing the need for cash transfers to alleviate the plight of vulnerable households while ensuring adequate grain reserves to sustain the country’s food security is a delicate task.

  • India’s diabetes epidemic is making its widespread TB problem worse

    diabetes

    What is the news?

    • India has long grappled with two major epidemics: type 2 diabetes (diabetes mellitus, DM) and tuberculosis (TB). With a staggering 74.2 million people living with diabetes and 2.6 million new TB cases each year, it is crucial to understand the deep interconnection between these diseases.

    Central Idea

    • The diabetes mellitus (DM) and tuberculosis (TB) are closely interconnected in India, with DM increasing the risk and severity of TB, and TB co-infection worsening diabetes outcomes. Among people with TB, the prevalence of DM was found to be 25.3% while 24.5% were pre-diabetic. Which highlights the need for urgent action to address this dual burden and improve care coordination for individuals affected by both diseases.

    What is type 2 diabetes?

    • Type 2 diabetes, also known as diabetes mellitus (DM), is a chronic metabolic disorder characterized by high blood sugar levels.
    • It is the most common form of diabetes and typically develops over time, often in adulthood.
    • In type 2 diabetes, the body either becomes resistant to the effects of insulin (a hormone that helps regulate blood sugar levels) or does not produce enough insulin to maintain normal glucose levels.

    What is tuberculosis (TB)?

    • TB is an infectious disease caused by the bacterium Mycobacterium tuberculosis.
    • It primarily affects the lungs but can also affect other parts of the body, such as the kidneys, spine, and brain.
    • TB is transmitted through the air when an infected individual coughs, sneezes, or speaks, releasing tiny droplets containing the bacteria. When inhaled by others, these droplets can lead to infection

    diabetes

    The interconnection and Impact of DM on TB

    • Increased Risk of TB: People with DM have a higher risk of developing TB compared to those without DM. DM weakens the immune system and impairs the body’s ability to fight off infections, including TB.
    • Increased TB Severity: When individuals with DM acquire TB infection, they tend to have a higher bacterial load, which means there are more TB bacteria in their bodies. This can result in more severe symptoms and complications associated with TB.
    • Delayed Sputum Conversion:
    • Sputum conversion refers to the transition from having TB bacteria detectable in the sputum (positive) to no longer having detectable bacteria (negative) after initiating treatment.
    • Individuals with both TB and DM often experience delayed sputum conversion compared to those with TB alone.
    • It means that it takes longer for the TB bacteria to be eliminated from their bodies, prolonging the infectious period and potentially increasing the risk of transmitting the disease to others.
    • Altered Treatment Outcomes:
    • TB treatment outcomes can be affected by the presence of DM. Individuals with both TB and DM may experience modified TB symptoms, radiological findings, and lung functioning compared to those with TB alone.
    • Studies have shown that individuals with TB and DM have reduced lung functioning even after completing TB treatment.
    • Respiratory Complications: Individuals with both TB and DM are more prone to experiencing respiratory complications related to TB. Respiratory complications can be a common cause of death in this population, highlighting the increased severity of TB when DM is present.

    What measures India must take to combat the dual burden of DM and TB

    • Integrated Care: Implement patient-centered care approaches that address the unique needs of individuals with both TB and DM, along with other comorbidities. This includes coordinated diagnosis and treatment, bidirectional screening, patient education, and support.
    • Holistic Treatment Plans: Strengthen high-quality care for TB, DM, and associated comorbidities by developing holistic treatment plans. Prioritize individual programs for TB and DM and ensure their integration into healthcare services.
    • Resilient Health Systems: Build and scale up resilient and integrated health systems by garnering increased commitment from stakeholders, formulating robust policy guidance, and mobilizing additional resources. These efforts will support the development of effective strategies to combat both diseases.
    • Data-Driven Decision Making: Enhance the research literature on TB and DM interactions to enable better decision-making. Access to comprehensive data and ongoing studies will provide critical insights for improving patient care and raising awareness of the impact of these interconnected diseases

    Conclusion

    • The coexistence of diabetes mellitus and tuberculosis in India demands immediate attention. By adopting integrated care models, improving treatment outcomes, and strengthening health systems, we can effectively address the dual burden of DM and TB. It is essential for health professionals, policymakers, and communities to prioritize research, enhance collaboration, and work together to improve the lives of those affected by these intertwined epidemics.

    monsoon

    What is the news?

    • Last weekend, parts of North India witnessed heavy rains that triggered flash floods and left a trail of destruction, tragically it resulted in at least 50 reported deaths. Himachal Pradesh was the worst affected. Several places in Haryana, Punjab and Himachal Pradesh reported record rainfall.

    Central idea

    • Last weekend, North India faced a calamity as torrential rains triggered flash floods and wreaked havoc across the region. Understanding the factors that led to this catastrophe is crucial in developing effective strategies to mitigate the impact of such extreme weather events in the future.

    Fundamental characteristics of monsoon rainfall in the region

    • Concentrated Timeframe: Monsoon rainfall in the region is not evenly distributed throughout the year. Instead, it occurs within a specific timeframe. All the seasonal rainfall (about 80-100 cm) falls within 130-150 hours, which is a relatively short period.
    • Heavy Rain Contribution: The heavy rains play a significant role in contributing to the overall seasonal precipitation. Half of the seasonal rainfall (40-50 cm) occurs in only 30-40 hours.
    • Runoff: When heavy rains occur, most of the rainwater drains away as runoff, particularly when the soil is already wet. This indicates that a substantial amount of rainfall does not get absorbed into the ground but flows off as surface runoff.

    Factors attributed to the Heavy Downpour in north India

    • Active Monsoon and Moisture Influx: An active monsoon season with strong winds in the lower air layers brought in moisture from the Bay of Bengal and the Arabian Sea. These moisture-laden winds contributed to the heavy rainfall in the region.
    • Atmospheric Forcing and Eastward Moving Troughs: Large-scale atmospheric forcing, in the form of outflows in the upper layers of the atmosphere, moved eastward through mid-latitude troughs. These troughs directed the flow of moisture towards the Himalayan region, exacerbating the intensity of the rainfall.
    • Orographic Uplift and Steep Terrain: The steep terrain of the Himalayas, combined with orographic uplift, played a significant role in intensifying the precipitation. When air masses encounter the mountains, they are forced to rise, resulting in enhanced rainfall.
    • Synoptic Conditions and Moisture Intrusion: The synoptic conditions during the period were conducive to heavy rainfall. The monsoon was active, with strong moist easterly winds entering the region. Additionally, there was moisture intrusion from the North Arabian Sea, further augmenting the rainfall.

    Increasing Trend of Extreme Rainfall

    • Tripled Number of Extreme Rainfall Events: Recent studies indicate that the number of extreme rainfall events, defined as rainfall exceeding 15 cm in 24 hours, has tripled in many parts of the country.
    • Prolonged Duration of Rainstorms: The duration of rainstorms has also tripled, indicating that rainfall events are lasting longer, potentially leading to higher rainfall accumulation.
    • Decreased Number of Rainy Days and Hours: The total number of rainy days and hours during the monsoon season has decreased. This means that when it does rain, it tends to be in the form of heavy downpours rather than spread out over more frequent but lighter rainfall events.
    • Regional Variation: Central India has been particularly affected by the increasing trend of extreme rainfall events, with a significant rise in both frequency and intensity.
    • Himalayan Region Prone to Extreme Rainfall: The Himalayan region, with its complex topography and varied weather patterns, is prone to extreme rainfall events. Studies indicate that 65 percent of areas in the region show a positive trend in the frequency of daily rainfall extremes.

    Impact of Arctic Warming on Monsoon Climate

    • Increased Frequency of Blocking Highs and Mid-latitude Troughs: Arctic warming has been observed to influence the monsoon climate through changes in mid-latitude circulation. As the Arctic warms and sea ice recedes, there is growing evidence of an increased frequency of blocking highs and deep mid-latitude troughs. These atmospheric patterns can affect weather systems and contribute to extreme rainfall events during the monsoon season.
    • Influence on Circulation Patterns: Observations and models suggest that Arctic warming can alter circulation patterns, including the movement of air masses, pressure systems, and wind patterns. These changes can have cascading effects on the monsoon climate, including the transport of moisture and atmospheric conditions that contribute to heavy rainfall events.
    • Impact on Monsoon Dynamics: The warming of the Arctic and subsequent changes in circulation patterns can affect the dynamics of the monsoon. This can lead to shifts in moisture inflow, atmospheric stability, and the timing and intensity of rainfall during the monsoon season.
    • Potential for Future Changes: As Arctic warming continues; it is expected that the impacts on the monsoon climate will persist and potentially intensify. This suggests that the influence of Arctic warming on the monsoon may contribute to further changes in extreme precipitation patterns and associated impacts in the future.

    Way forward: Mitigation Strategies for Flooding

    • Robust Early Warning System: Implement a comprehensive early warning system that utilizes meteorological observations, including Doppler weather radar and high-resolution numerical weather prediction models. Advanced technologies like artificial intelligence and machine learning can aid in interpreting the data, enhancing the accuracy and timeliness of alerts.
    • Continuous Monitoring and Flood Warning Systems: Continuously monitor rainfall patterns, river levels, and deploy an advanced flood warning system. This integrated approach allows for timely response and evacuation plans to safeguard vulnerable communities.
    • Flood Risk Maps: Develop flood risk maps incorporating topography, historical flood data, and hydrological modeling. These maps can identify high-risk zones and guide targeted actions to enhance preparedness and resilience.
    • Climate-Resilient Infrastructure: Improve and maintain climate-resilient infrastructure, including robust drainage systems and channels, to prevent waterlogging and minimize flood damage.
    • Land Use Planning and Zoning Regulations: Implement effective land use planning and zoning regulations, designating flash flood-prone areas as non-residential or restricted zones to mitigate potential risks.
    • Protection and Restoration of Natural Ecosystems: Prioritize the protection and restoration of natural ecosystems such as forests and wetlands. These natural buffers can absorb rainfall and reduce runoff, mitigating the intensity of floods.
    • Public Awareness Campaigns: Conduct widespread awareness campaigns to educate individuals on flood response and preparedness. Encourage actions such as evacuation planning, first aid knowledge, and reliance on credible sources of information during emergencies

    Conclusion

    • Recognizing the escalating threat of extreme precipitation events and implementing proactive measures are pivotal in improving India’s resilience to climate-induced disasters. Building resilience is crucial to safeguarding vulnerable communities and ensuring a sustainable future for the nation.

    Central Idea

    • Researchers have discovered that the population of ospreys, a fish-eating bird, is facing a decline due to the decreasing numbers of Atlantic menhaden, their primary food source.
    • The depletion of menhaden, a small silvery fish, is attributed to commercial fishing practices.
    • The decline in osprey reproduction reflects the broader ecological impact of reduced menhaden numbers.

    About Atlantic Menhaden

    • Atlantic menhaden, scientifically known as Brevoortia tyrannus, is a species of fish belonging to the Clupeidae family.
    • They are commonly found along the Atlantic coast of North America, ranging from Florida to Nova Scotia.
    • Atlantic menhaden play a vital ecological role and have significant commercial and ecological importance.

    Importance of Atlantic Menhaden

    • Role in Coastal Ecosystem: Menhaden play a crucial role in the ecology of coastal waters along the Eastern Seaboard, providing sustenance for larger fish, marine mammals, and birds.
    • Nutrient-Rich and Filtering Capacity: Menhaden are nutrient-rich, containing omega-3 fatty acids, and they filter substantial quantities of ocean water while consuming smaller organisms like plankton.

    Commercial Fishing Impact

    • Increased Catch Allowance: The Atlantic States Marine Fisheries Commission raised the allowable catch of menhaden to 233,550 metric tons for the next two years, a 20% increase from previous years.
    • Fishery Quota: The commission maintained a quota of 51,000 metric tons for the Chesapeake Bay’s reduction fishery, where menhaden are used for bait and fish products.
    • Ecological Concerns: Critics argue that the removal of significant menhaden quantities is degrading the ecosystem, negatively affecting species like ospreys and striped bass that rely on menhaden.

    Low Reproductive Numbers and Menhaden Depletion

    • In mid-June, researchers found only three young ospreys out of 84 nests checked in Mobjack Bay, part of the Chesapeake Bay.
    • Scientists at the College of William & Mary, monitoring the local osprey population for over 50 years, recorded the lowest reproductive number.
    • The decline in breeding success is attributed to the depletion of Atlantic menhaden, the osprey’s primary food source.

    Lawsuit and Ecosystem Protection

    • Recreational Fishermen Lawsuit: A group of recreational fishermen from Maryland sued the Virginia Marine Resources Commission, claiming it contributed to the menhaden decline by endorsing quotas that harm fish populations and the recreational fishing industry.
    • Commercial Fishing Practices: Critics highlight the negative impact of industrial techniques used by companies like Omega Protein, which catch menhaden in unsustainable quantities, contributing to the decline of other species and damaging ecosystems.
    • Restoring Menhaden Stocks: Non-profit organizations advocate for rebuilding menhaden populations along the Atlantic and Gulf of Mexico coasts to maintain a balanced ecosystem.

    Positive Signs beyond Chesapeake Bay

    • Menhaden Recovery: Outside the Chesapeake Bay, menhaden populations have increased since the Atlantic commission took measures to address overfishing in 2012, leading to a recovery of the fish population within two years.
    • Ecological Impact: The recovery of menhaden populations has brought back various predators such as humpback whales, tuna, sharks, and bald eagles off the coasts of New York and New Jersey.
