    The issue with India’s tree planting schemes

    Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Why in the news? 

    India’s tree planting schemes have garnered attention as part of the country’s efforts to combat climate change and restore degraded ecosystems. However, these initiatives face several challenges and criticisms.

    Recent Trends of Special Conservation Drives:

    • Increased Initiatives: There has been a surge in global and national tree planting drives, such as the “One Trillion Project” by the World Economic Forum, Pakistan’s “10 Billion Tree Tsunami,” China’s “Great Green Wall,” and the “Bonn Challenge” to restore degraded landscapes.
    • High Media Attention: These drives often feature catchy slogans and glamorous campaigns that attract substantial media attention and public involvement.
    • Annual Events: India celebrates Van Mahotsava annually in July, aiming to promote tree planting and environmental conservation.

    Issues Associated with These Drives:

    • Limited Community Participation: Many programs lack significant involvement from local communities, affecting their effectiveness and sustainability.
    • Post-Planting Measures: Insufficient focus on post-planting care and monitoring hinders the success of tree planting efforts.
    • Monoculture Risks: Some drives promote monoculture, which can be detrimental to biodiversity and carbon sequestration.
    • Ecological Impact: Inappropriate tree planting in non-deforested areas like grasslands or animal habitats can damage ecosystems, increase wildfire risk, and exacerbate global warming.

    India’s Accountability and Challenges Toward Environmental Goals:

    • Achievements: India claims to have fulfilled its Paris Agreement commitments and achieved an additional carbon sink of 1.97 billion tonnes of CO2 equivalent.
    • Encroachment and Loss: Approximately 10 million hectares of Indian forests are under encroachment, and about 5.7 million hectares have been lost for non-forestry purposes.
    • Dependence on Forests: Nearly 27.5 crore people rely on forests for subsistence, highlighting the importance of sustainable management.
    • Restoration Goals: India aims to restore 26 million hectares of degraded forests by 2030, but faces challenges such as encroachment and the need for effective tree planting strategies.

    Way forward: 

    • Community Involvement: Need to foster local participation in tree planting drives by involving communities in planning, execution, and ongoing maintenance.
    • Monitoring and Maintenance: Try to implement robust post-planting monitoring and care systems to ensure the survival and growth of planted trees.
    • Policy and Strategy Improvements: To address criticism of mass planting drives, India needs to prioritize adequate financing, active community participation, and technical considerations in forestry and restoration strategies.

  • Capital Markets: Challenges and Developments

    Decline in popularity of Equity Linked Savings Schemes (ELSS)

    Prelims Only | Economics | Mains Paper 3: Indian Economy

    Why in the News?

    • Equity Linked Savings Schemes (ELSS) are mutual fund schemes that offer tax benefits under Section 80C of the Income Tax Act.
      • Recently, ELSS has seen a decline in popularity, with more money being withdrawn from these schemes than invested.

    What is Section 80C of the Income Tax Act?

    • Section 80C permits certain investments and expenses to be tax-exempted.
    • By well-planning the 80C investments that are spread diversely across various options like National Savings Certificate (NSC), Unit Linked Insurance Plan (ULIP), Public Provident Fund (PPF), etc., an individual can claim deductions up to Rs 1,50,000.
    • By taking tax benefits under 80C, one can avail of a reduction in tax burden.

    About Equity Linked Savings Schemes (ELSS)

    • An ELSS fund or an equity-linked savings scheme is the only kind of mutual funds eligible for tax deductions under the provisions of Section 80C of the Income Tax Act, 1961.
    • Investors can claim a tax rebate of up to Rs 1,50,000 and save up to Rs 46,800 a year in taxes by investing in ELSS mutual funds.
    • ELSS mutual funds’ asset allocation is mostly (65% of the portfolio) made towards equity and equity-linked securities such as listed shares.
    • They may have some exposure to fixed-income securities as well.
    • These funds come with a lock-in period of 3 years only, the shortest among all Section 80C investments.
    • Being market-linked, they are subject to market risk, but may offer potentially higher returns compared to traditional tax-saving instruments like National Savings Certificate (NSC) or Public Provident Fund (PPF).

    Recent Trends in ELSS

    • In the past few months, more money has been taken out of ELSS than put in.
    • For example, last month ₹445 crore was withdrawn, while in April it was ₹144 crore.
    • In the last fiscal year, only ₹1,041 crore was invested in ELSS, compared to ₹7,744 crore the previous year.

    Impact of the New Tax Regime

    • A new tax regime was introduced in 2020-21, which is now the default option.
    • The old tax regime offered various tax exemptions and deductions, helping to reduce income tax.
    • These benefits are not available under the new tax regime, making ELSS less attractive to investors.

  • e-Commerce: The New Boom

    The State of India’s Informal Economy    

    Explained | Economics | Mains Paper 3: Indian Economy

    Why in the news? 

    The NSSO’s 2021-22 and 2022-23 survey outcomes reveal effects of significant economic shocks due to demonetisation, GST implementation, and the COVID-19 pandemic on India’s economy.

    About NSSO: 

    • The NSSO is India’s premier agency for conducting large-scale nationwide sample surveys on socio-economic aspects that collects data on employment, consumption, health, education, and other areas to provide essential inputs for policy and planning.
    • The NSSO was merged with the Central Statistical Office in 2019 to form the National Statistical Office.

    Key highlight as per the recent survey by NSSO   

    • Impact of Economic Shocks: The surveys reflect the aftermath of major economic events such as demonetisation (November 2016), the rollout of GST (July 2017), and the COVID-19 pandemic (starting March 2020).
    • Employment Trends: There has been a noticeable decline in employment within the informal sector over the past seven years, with around 16.45 lakh jobs lost.
    • Sectoral Dynamics: The unincorporated manufacturing sector saw a significant contraction, with the number of enterprises declining by 9.3% from 19.7 million in 2015-16 to 17.82 million in 2022-23.

    What are unincorporated enterprises?  

    • Unincorporated enterprises are informal businesses not legally registered as companies.
    • They include MSMEs, household units, own-account enterprises, and partnerships, operating outside formal regulatory frameworks but contributing significantly to employment and economic activity.

    Why are these survey results important and what do they represent?  

    • Timely Insights: These survey results offer current data crucial for understanding the evolving role of the informal sector in job creation, particularly during economic slowdowns when formal sector employment may decline.
    • Impact Assessment: They provide a detailed analysis of how significant economic events like demonetisation, GST implementation, and the COVID-19 lockdowns have affected the informal sector, highlighting vulnerabilities and resilience.
    • Policy Relevance: The findings inform policymaking aimed at supporting and regulating the informal sector, ensuring that measures address its unique challenges and contributions to overall economic stability and inclusivity.

    What has been the pattern of ‘Informal Employment’ across states?

    • The data shows a mixed pattern across states, with 16 out of 34 states/UTs recording a decline in informal sector workers in 2022-23 compared to 2015-16.
    • Around 63 lakh informal enterprises shut down due to GST between 2015-16 and 2022-23, resulting in a loss of about 1.6 crore jobs.
    • The number of informal enterprises plunged from 50.32 lakh with 85.6 lakh workers in April-June 2021 at the peak of the COVID-19 second wave, to 1.91 crore firms with 3.12 crore employees in January-March 2022.

    Way Forward: 

    • The government should provide targeted support and incentives to help informal enterprises adapt to the post-GST and post-pandemic environment.
    • Policymakers should aim to facilitate a gradual transition of informal enterprises to the formal sector.

  • Women empowerment issues – Jobs,Reservation and education

    On political representation of women  

    Explained | Indian Society | Mains Paper 2: Representation Of People’s Act

    Why in the News?

    In the recently concluded general elections in the U.K., a record 263 women MPs, making up 40% of the total, have been elected to the House of Commons.

    Political representation of Women in the world: 

    Have women been fairly represented in Parliament in independent India?

    Women were granted the right to vote from the First General Elections in 1952, yet their representation in the Lok Sabha has been low.

    • Statistics about women’s representation: The women’s representation in Lok sabha in between of  1952 and 2004 was about ranged from 5% to 10%.
      • The percentage women’s representation had increased to 12% in 2014 and stands at 13.6% in the 18th Lok Sabha while in the Rajya Sabha (upper house), the figure is 13%.
    • Constitutional Amendments: The 73rd and 74th amendments in 1992/1993 provided one-third reservation for women in panchayats and municipalities, but similar reservations for the Lok Sabha and State assemblies have not been successful until recently.

    Note: The global average of 26.9% of women in National parliaments.

    Women’s Representation in State Legislatures:

    • No state has more than 20% women representation in its legislative assembly.
    • Chhattisgarh has the highest representation with 18% women MLAs.
    • Himachal Pradesh has just one woman MLA and Mizoram has none.

    Should political parties provide internal reservations to increase women’s political participation?

    • Globally, higher representation for women is achieved through voluntary or legislated compulsory quotas for candidates within political parties or reserved seats in parliament.
    • So, quotas within political parties offer more democratic choices to voters and flexibility in candidate selection. It means quota in Political parties could be the most important step to increase women’s representation in Parliament.
    • Some parties, like Naam Tamilar Katchi in Tamil Nadu, have adopted voluntary quotas (50% for women candidates), but such measures alone have not significantly improved overall representation.

    When will the 106th constitutional amendment be implemented?

    • The 106th Amendment Act provides for 33% reservation for women in the Lok Sabha and state legislative assemblies, including the Delhi Legislative Assembly.
    • The reservation will come into effect after an exercise of delimitation is undertaken following the first census conducted after the commencement of the 106th Amendment Act.
    • The women’s reservation will be in operation for a period of 15 years from its commencement.

    Way Forward: 

    • Public Awareness and Advocacy: Need to conduct widespread awareness campaigns to highlight the importance of gender equality in political representation.
    • Capacity Building and Support Mechanisms: Need to implement comprehensive capacity-building programs aimed at empowering women politically. For example,provide training in leadership skills, campaign management, and legislative processes.

    Choosing the right track to cut post-harvest losses

    Explained | Agriculture | Mains Paper 3: Agriculture and related issues

    Why in the News? 

    India holds the position of the second-largest agricultural producer globally however, it only accounts for 2.4% of global agricultural exports, ranking eighth worldwide due to the post-harvest loss.

    A closer look at India’s post-harvest loss:

    • Economic Impact: India faces annual post-harvest losses amounting to approximately ₹1,52,790 crore, significantly impacting farmer incomes and the agricultural economy.
    • Perishable Commodities: The biggest losses occur in perishable commodities like livestock produce (22%), fruits (19%), and vegetables (18%). Export processes further add to these losses, particularly at the import-country stage.
    • Supply Chain Inefficiencies: There is Inefficiencies in storage, transportation, and marketing, alongside a lack of assured market connectivity, contribute to significant post-harvest losses. Small and marginal farmers, who make up 86% of the farming community, struggle with economies of scale and market access.

    Initiatives taken by the Railways Department:

    • Truck-on-Train Service: Indian Railways introduced the truck-on-train service, allowing loaded trucks to be transported on railway wagons. This service has been expanded following successful trials with commodities like milk and cattle feed.
    • Parcel Special Trains: During the COVID-19 pandemic, the Railways introduced parcel special trains to transport perishables and seeds between producers and markets, ensuring timely delivery and reducing post-harvest losses.
      • The DFI (Doubling farmers’ income) committee recommends streamlining loading and unloading processes to minimize transit times and address staffing shortages through recruitment and training initiatives.
    • Kisan Rail Scheme: It was launched to connect production surplus regions with consumption regions. This scheme facilitates the transportation of perishables (including milk, meat, and fish) more efficiently.
    • Specialized Wagons and Facilities: Investment in specialized wagons for temperature-controlled transport and establishing rail-side facilities for safe cargo handling are essential steps taken by the Railways.

    Way for Untapped Opportunities:

    • Enhanced Environmental Benefits: Rail transport generates up to 80% less carbon dioxide for freight traffic compared to road transport.
    • Public-Private Partnerships: The private sector can play a crucial role in enhancing operational efficiency and strengthening rail infrastructure through public-private partnerships, thereby improving the overall logistics ecosystem for agricultural produce.
    • Budgetary Support and Infrastructure Development: The budgetary allocation for agriculture in 2024 aims to bridge the farm-to-market gap with modern infrastructure and value-addition support.
    • Technology Integration: Incorporating advanced technologies like real-time tracking, temperature monitoring, and automated loading/unloading systems.

    Way forward: 

    • Expand climate-controlled storage facilities and cold storage capacity to accommodate a larger share of agricultural produce.
    • Provide small and marginal farmers access to storage facilities through cooperatives or subsidies.
    • Invest in specialized rail wagons for temperature-controlled transport and establish rail-side cargo handling facilities.

    The problems with sub-caste reservations

    Explained | Polity | Mains Paper 2: Indian Constitution – historical underpinnings, evolution, features, amendments, significant provisions and basic structure

    Why in the News?

    The Supreme Court has reserved its decision on sub-caste reservations for SC/STs. Any ruling on this matter must be substantiated not only legally but also academically.

    What is the Sub-categorization of castes?

    It refers to the practice of further dividing larger caste categories into smaller groups or sub-groups based on specific criteria such as socio-economic status, geographical location, historical background, or specific needs for policy implementation.

    Background of the Case:

    • The case involves the validity of sub-classification within the SC and ST categories for providing reservations in government jobs and education.
    • In 2004 Supreme Court strikes down Andhra Pradesh Scheduled Castes (Rationalisation of Reservations) Act, 2000, citing violation of the right to equality in the E.V. Chinnaiah v State of Andhra Pradesh case and emphasised that the SC list should be treated as a single, homogeneous group
      • Only Parliament has the power to sub-classify SCs and STs for reservations
      • The Supreme Court is now considering whether states have the power to create sub-classifications within these reserved categories.
    • The case stems from a 1975 Punjab government notification that divided its 25% reservation for SCs into two categories: half for Balmikis (Valmikis) and Mazhabi Sikhs, and the other half for the remaining groups within the SC category.

    Objectives behind the implementation of reservations and present SC scenario:

    • Objective of Reservations: The primary objective of reservations, as advocated by Dr. B.R. Ambedkar, is to ensure equitable representation and opportunities for historically marginalized communities, particularly Scheduled Castes (SCs).
    • Present SC scenario: Despite reservations, certain sub-castes within SCs continue to face challenges in securing adequate representation in jobs and education. This under-representation is often attributed to factors such as inadequate educational opportunities, economic disparities, and historical discrimination.

    The policy of economic empowerment in India and its associated challenges:

    • Policies for Economic Empowerment: These policies complement reservations by focusing on enhancing the ownership of capital assets (like land and businesses) and improving educational attainment among SC individuals
      • For example, Self-Employment Scheme for Rehabilitation of Manual Scavengers (SRMS), National Scheduled Castes Finance & Development Corporation (NSFDC) and National Safai Karamcharis Finance & Development Corporation (NSKFDC).
      • These policies are aimed at building capabilities and enabling greater participation in economic activities.
    • Challenges: There are challenges in implementing economic empowerment policies including inadequate access to credit and financial resources, lack of skill development initiatives, and persistent socio-economic barriers that hinder the upward mobility of SC communities.
      • Intersection with Reservations: Integrating economic empowerment with reservations is crucial to ensure that individuals from SC backgrounds not only secure reserved positions but also have the necessary skills and resources to thrive in competitive environments.

    What must be our focus? (Way Forward)

    • Holistic Approach: There is a need for a holistic approach that combines reservations with targeted economic and educational interventions. This approach should address both systemic discrimination and socio-economic barriers faced by SC communities.
    • Capacity Building: There should be emphasis on enhancing the educational infrastructure and skill development programs tailored to the needs of SC individuals.
    • Data-Driven Policy: The policy decisions related to sub-caste reservations should be informed by empirical data that assesses the actual impact of discrimination versus socio-economic factors on under-representation.

    • NASA launched the LRO on June 18, 2009.
    • LRO’s primary mission is to map the Moon’s surface in high detail to identify safe landing sites and locate potential resources.
    • It is equipped with seven scientific instruments, including a camera, a laser altimeter, and a radiation detector.
    • LRO has provided critical data on lunar topography, temperature, and radiation levels, significantly enhancing our understanding of the Moon.

    Characteristics of Lunar Caves

    • Craters are bowl-shaped and result from asteroid or comet strikes.
    • Pits, in contrast, appear as massive steep-walled depressions.
    • At least 200 such pits have been discovered, with 16 believed to have formed from collapsed lava tubes due to volcanic activity over a billion years ago.

    Benefits for Human Exploration

    • The Moon is exposed to solar radiation 150 times stronger than Earth.
    • The lunar surface heats to about 127 degrees Celsius during the day and cools to around -173 degrees Celsius at night.
    • Caves, however, maintain stable average temperatures of around 17 degrees Celsius.
    • They could shield human explorers from radiation and micrometeorites, making them viable for future lunar bases or emergency shelters.

    Challenges and Further Research

    • The depth of such caves could present challenges for accessibility.
    • There are risks of potential avalanches and cave-ins.

    Need for Further Research

    • Further research is needed to understand and map the structural stability of the caves.
    • This could be done using ground-penetrating radar, robots, or cameras.
    • To become viable habitats, caves would need systems to monitor movement or seismic activity and safety zones for astronauts in case of a cave collapse.
