  • Dam Safety Act 2021

    hydel dam safety

    Central Idea

    • India boasts nearly 6,000 large dams, but concerns loom over the safety of these structures, with approximately 80% of them being over 25 years old and posing safety risks.
    • With numerous large dams and hydropower projects, the Himalayas play a crucial role in meeting India’s energy needs.
    • However, the recent incident of a Glacial Lake Outburst Flood (GLOF) in North Sikkim has raised alarm bells about the safety of these structures.

    Hydropower boom in the Himalayas

    • As of November 2022, the Himalayan states and Union territories, excluding West Bengal, had 81 large hydropower projects (above 25 MW) in operation, with 26 more under construction.
    • An additional 320 large projects are in the planning stages, according to the Central Electricity Authority under the Union Ministry of Power.

    Discussion: Dam Safety in the Himalayas

    • Vulnerability to Natural Hazards: The Himalayas are highly susceptible to natural hazards such as earthquakes, landslides, and GLOFs due to their complex geological and topographical features. These hazards can jeopardize the integrity of dams and reservoirs.
    • High Population Density: The Himalayan region is densely populated, with communities residing downstream of dams and hydropower projects. A dam failure can have devastating consequences on human lives and property.
    • Ecological Sensitivity: The Himalayas are an ecologically fragile region with unique biodiversity. A dam failure can lead to environmental disasters, impacting delicate ecosystems.

    Repercussions

    • Climate Change: The melting of glaciers due to global warming contributes to the formation of glacial lakes. As these lakes grow, the risk of GLOFs increases, putting downstream infrastructure at risk.
    • Snowball Effects: Landslide dams can lead to impounding of lakes, landslide-induced floods, secondary landslides, channel avulsion, and the formation of flood terraces downstream, impacting communities and infrastructure.
    • Delayed Impacts: Run-of-the-river projects, which often bypass large-scale displacement and forest diversion, have been promoted as environmentally friendly. However, their underground components can disturb geology and geohydrology, leading to indirect displacement and environmental impacts.
    • Aging Infrastructure: Many dams and hydropower projects in the Himalayas are aging, with approximately 80% of them over 25 years old. Proper maintenance and monitoring are essential to ensure their safety.

    Dam Safety Act, 2021 and its Provisions

    • The DSA was introduced in response to dam failures caused by deficient surveillance and maintenance.
    • It establishes key responsibilities and requires the formation of national and state-level bodies for its implementation.
    • The Act outlines the following provisions:
    1. National Committee on Dam Safety: Responsible for overseeing dam safety policies and regulations.
    2. National Dam Safety Authority: Tasked with implementing and resolving state-level disputes.
    3. Chairman of the Central Water Commission (CWC): Heads dam safety protocols at the national level.
    4. State Committee on Dam Safety (SCDS) and State Dam Safety Organisation (SDSO): To be established at the state level.

    Challenges in DSA Implementation

    • Inadequate Risk Assessment: Experts argue that the DSA does not encourage risk-based decision-making and lacks transparency incentives.
    • Transparency Concerns: Dam safety should be a public function, with information readily accessible. However, transparency is impeded when government employees and project engineers dominate national and state bodies, potentially compromising objective decision-making.

    Lessons Learned from Recent Incidents

    • Comprehensive Risk Assessment: Dam safety protocols must include comprehensive risk assessments that consider factors such as climate change, geological stability, and the potential for GLOFs. Periodic reviews yield updated inundation maps and rule curves for reservoir capacity.
    • Hazard Profiling Issues: Hazard risk is influenced by climate change, urbanization, and water usage patterns. Periodic reviews should yield updated inundation maps and rule curves for reservoir capacity. Unfortunately, these reviews are often overlooked or findings are not made publicly available.
    • Standardized Safety Evaluation: The DSA mandates comprehensive dam safety evaluations but lacks standardization in how failures are analyzed and reported.
    • Transparent Reporting: Transparency in dam safety is paramount. The DSA should be implemented rigorously, with an emphasis on transparent reporting of dam failures and safety assessments.
    • Community Involvement: Local communities should be actively engaged in dam safety measures. They can provide valuable insights into the environmental and social impacts of such projects.

    Way Forward

    • Early Warning Systems: Establishing advanced early warning systems that can detect GLOFs and other potential hazards is crucial. These systems can save lives and minimize damage.
    • Regular Maintenance: Aging infrastructure must undergo regular maintenance and upgrades to ensure their continued safety and functionality.
    • International Collaboration: Given the transboundary nature of the Himalayan region, international collaboration on dam safety and disaster management is essential. Neighboring countries should work together to mitigate shared risks.
  • Leniency Plus Norms to curb Cartelisation

    Central Idea

    • The Competition Commission of India (CCI) has unveiled a draft of revised lesser penalty regulations, introducing a groundbreaking “Leniency Plus” Norms and shedding light on its strategy for combating cartels.

    About Competition Commission of India (CCI)

    • The CCI is the chief national competition regulator in India.
    • It is a statutory body within the Ministry of Corporate Affairs.
    • It is responsible for enforcing The Competition Act, 2002 in order to promote competition and prevent activities that have an appreciable adverse effect on competition in India.

    Understanding “Leniency Plus”

    • Existing Leniency Program: Under the current Competition Act 2002, a leniency program allows companies to receive partial immunity from penalties if they provide substantial information about their involvement in a cartel. This aids competition authorities in uncovering secret cartels and obtaining insider evidence.
    • Additional Reduction in Penalty: In the “Leniency Plus” framework, a cartel member cooperating with CCI for leniency can disclose the existence of another unrelated cartel during the original leniency proceedings. In return, they receive an additional reduction in penalties.
    • Incentivizing Disclosure: “Leniency Plus” serves as a proactive antitrust enforcement strategy, encouraging companies already under investigation for one cartel to report other undisclosed cartels, thus promoting transparency.

    Legal foundation

    • Legal basis: The “Leniency Plus” regime was incorporated into the Competition (Amendment) Act 2023, which received Presidential approval in April of the same year.
    • Global Adoption: The concept of “Leniency Plus” is not new, as it is already recognized and practised in jurisdictions like the UK, US, Singapore, and Brazil.
    • Encouraging Disclosure: One of the key aspects of these regulations is their encouragement for companies already under investigation for one cartel to report other undisclosed cartels to the competition regulator.

  • How are Symbols allotted to Political Parties in India?

    symbols

    Central Idea

    • A recent Supreme Court decision declining a plea by a political party in Telangana, questioning the allocation of election symbols, has thrown the spotlight on the intriguing world of political symbols in India.
    • This article delves into the process of symbol allocation and its role in shaping the country’s political landscape.

    Symbols Allocation Authority: ECI

    • The ECI is responsible for allocating symbols to political parties, following guidelines laid out in The Election Symbols (Reservation and Allotment) Order, 1968.
    • This order aims to regulate symbol specification, reservation, choice, and allotment during elections.

    Types of Election Symbols

    • Reserved and Free Symbols: Symbols can be either reserved, exclusively assigned to recognized political parties, or ‘free’ symbols that can be chosen by unrecognised registered parties’ candidates. Unrecognized parties are those that haven’t met the criteria for state party recognition.
    • Exclusive Symbols: Recognized national and state parties are granted exclusive symbols, signifying their established status.

    Symbol Selection by Parties

    • Preference Lists: Unrecognized parties provide a list of ten preferred symbols from the free symbol pool.
    • Proposal of New Symbols: Parties can propose up to three new symbols for consideration, provided they do not resemble reserved or free symbols, carry religious or communal connotations, or depict birds or animals.
    • Common Symbol Assignment: The ECI may allot a proposed symbol as a common symbol for the party if it deems it suitable.

    Historical Origins of Symbols

    • Sketching Process: Symbols were initially sketched by MS Sethi, who retired from the ECI in 1992. These symbols were conceived through brainstorming sessions where the goal was to identify objects that the common man could relate to.
    • Birth of Familiar Symbols: Many iconic symbols such as the bicycle, elephant, and broom originated from these sessions.
    • Unconventional Entries: Some lesser-known symbols like a pair of glasses, a nail cutter, and a neck-tie were also suggested, reflecting the diversity of ideas.
    • Modern Additions: Over time, new symbols like a bowl of noodles and a mobile charger have been included in the symbol list, reflecting contemporary times.

    Political Parties’ Say

    • Preference Submission: Unregistered parties submit their symbol preferences from the list of free symbols.
    • Proposal of New Symbols: Parties can suggest up to three new symbols with clear designs and drawings.
    • Criteria for Approval: Proposed symbols must not resemble existing reserved or free symbols, possess religious or communal connotations, or depict birds or animals.

    Symbol Allocation in Split Parties

    • Decision by ECI: When recognized political parties split, the ECI determines the symbol assignment. For example, the Congress party’s symbol evolved from a pair of bulls to the current hand symbol due to splits.
    • Recent Example: The ECI assigned different symbols to factions of the Shiv Sena, allowing one faction to retain the bow and arrow symbol while allotting a flaming torch to the other.

    Conclusion

    • The allocation of election symbols in India is a meticulous process governed by the ECI’s guidelines.
    • These symbols hold profound significance in political campaigns, representing parties’ identities and ideologies.
    • Understanding the history and intricacies of symbol allocation provides valuable insights into India’s dynamic political landscape.
  • RBI’s $5 Billion Forex Swap Matures

    Central Idea

    • As a $5 billion forex swap between the Reserve Bank of India (RBI) and banks approaches maturity, it signifies the central bank’s strategic move to manage liquidity and mitigate inflationary pressures.

    What is RBI’s Forex Swap?

    • Forex Tool: The Dollar–Rupee Swap is a forex tool employed by the RBI to exchange its currency with banks for another currency.
    • Buy/Sell Swap: It involves two variants: Dollar–Rupee Buy/Sell Swap, where the RBI buys dollars from banks in exchange for Indian Rupees, and then commits to selling the dollars back at a later date.
    • Sell/Buy Swap: Conversely, the RBI may sell dollars, thereby withdrawing an equivalent sum in rupees, reducing liquidity in the financial system.
    • Risk Mitigation: These swap operations are characterized by predetermined transaction terms, eliminating exchange rate and market risks.

    The Strategy behind

    • USD 5 Billion Swap: The RBI initiated a USD 5.135 billion swap with banks and aims to repurchase the dollars at the lowest possible premium after a two-year tenor.
    • Lower Range Bids: Banks bidding at the lower end of the premium range are more likely to succeed in the auction.

    Rationale for RBI’s Action

    • Surplus Liquidity: The Indian financial system currently experiences surplus liquidity, amounting to Rs 7.5 lakh crore, necessitating measures to curb potential inflation.
    • Traditional Tools: Traditional methods like increasing the repo rate or Cash Reserve Ratio (CRR) can negatively impact the economy and may not lead to complete transmission of monetary policy.
    • Previous Toolkit: The RBI used Variable Rate Reverse Repo Auction (VRRR) but encountered under-subscription due to better yields in the cash market.
    • Longer-Term Strategy: As a result, the RBI opted for forex auctions as a longer-term liquidity adjustment tool.

    Impact of the Swap

    • Liquidity Reduction: The primary effect is the reduction of liquidity, which currently stands at an average of Rs 7.6 lakh crore.
    • Strengthening Rupee: Increased dollar inflow will strengthen the Indian Rupee, which has already appreciated against the US dollar.
    • Inflation Control: The RBI typically tightens liquidity when inflation risks are elevated. Factors contributing to inflation include rising oil prices due to the Russia-Ukraine conflict and foreign portfolio investors withdrawing funds from Indian stocks.

    Conclusion

    • The RBI’s forex swap strategy emerges as a strategic tool to manage liquidity, stabilize the currency, and control inflationary pressures.
    • By reducing system liquidity and strengthening the rupee, the central bank aims to navigate the challenges posed by global events and ensure economic stability in India.
  • Places in news: Edakkal Caves

    Edakkal Caves

    Central Idea

    • Kerala Tourism has launched a project to improve civic amenities around the Edakkal Caves in Wayanad, known for its rock art from prehistoric times.

    About Edakkal Caves

    • The Edakkal Caves are situated in the Wayanad district of Kerala on Ambukutty Mala, a prominent hill in the region
    • It is not a typical cave but rather a natural cleft, rift, or rock shelter created by a piece of rock splitting away from the main body.
    • It was discovered in 1890 by Fred Fawcett, a British police official.
    • The caves are also known as “Ampukuthy Mala,” with a local belief that they were created by Rama’s sons, Lava and Kusha, who struck arrows on the mountain.

    Significance of the caves

    • Historical Significance: The caves are historically significant as they are situated near an ancient trade route connecting the high mountains of Mysore to the ports of the Malabar Coast.
    • Pictorial Writings: Inside the Edakkal Caves, there are pictorial writings believed to date back to at least 6,000 BCE during the Neolithic period.
    • Unique Stone Age Carvings: The Stone Age carvings are rare and represent the only known examples from South India, which belong to the Mesolithic era.
    • Cultural Significance: The petroglyphs found include depictions of human and animal figures, tools used by humans, and enigmatic symbols yet to be deciphered, indicating a rich cultural and historical heritage.
    • Indus Valley Connect: Some of the paintings found in the Edakkal Caves, particularly those of a “man with jar cup,” have led to speculation about a possible connection to the Indus Valley civilization.
  • Visa Shopping in India: Legal Implications and Opportunities

    Visa Shopping

    Central Idea

    • The practice of ‘visa shopping’ is on the rise across various Indian states, most notably in Punjab, where travel agencies facilitate this process.

    Understanding Visa Shopping

    • Definition: ‘Visa shopping’ entails obtaining visas for countries one may or may not intend to visit during the visa’s validity period.
    • Purpose: Individuals opt for this practice to secure access to their preferred countries, especially in Europe, even if they possess visas for other European nations.
    • Planning for the Future: Some acquire visas for countries they do not plan to visit immediately, strategically increasing their chances of obtaining visas for their desired destinations later, given the lengthy and uncertain visa application processes.

    Exploiting the Schengen System

    • Schengen Visa: This visa exemplifies ‘visa shopping’ as it offers a unique opportunity to explore multiple European countries without the need for separate visas.
    • Schengen Agreement: Established in 1985, the Schengen system allows free movement between member countries, comprising over 24 nations, sans border controls.
    • Single Visa, Multiple Countries: Obtaining a Schengen Visa from one of its member countries, such as Germany, France, or Italy, grants entry into the entire Schengen region.

    Case Scenarios

    • Easier Application Process: Many applicants prefer to secure a Schengen Visa from a country with a more straightforward application process.
    • Success Stories: Instances include individuals who, after facing rejection for a Spanish or German visa, obtained visas for other Schengen nations, enabling them to reach their intended destinations.

    Visa Shopping and Legal Issues

    • Compliance with Norms: The practice is legal as long as travellers adhere to visa process norms and obtain legitimate permission to stay in the country.
    • Intent Matters: Legal complications arise when individuals seek visas for one country but actually intend to stay in another or use it merely as an entry point.
    • Estonian Embassy’s Caution: The Embassy of Estonia in New Delhi cautioned against visa shopping, emphasizing that travellers must apply for a visa from the country where they plan the maximum stay.

    Consequences of Suspected Visa Shopping

    • Thorough Scrutiny: Embassies now conduct comprehensive checks of travel plans to detect visa shopping.
    • Potential Consequences: Suspected individuals may face visa refusal, being offloaded from flights, or deportation from EU borders.
    • Official Suspicion: Repeated engagement in visa shopping can arouse suspicion among immigration officials, leading to potential problems during travel.
  • Report Calls for Global Minimum Tax on Billionaires

    Tax

    Central Idea

    • The release of the ‘Global Tax Evasion Report’ marks a pivotal moment in the global fight against tax evasion.
    • This report serves as a comprehensive analysis of the state of global taxation and its implications.

    About Global Tax Evasion Report

    • The ‘Global Tax Evasion Report’ is compiled by the EU Tax Observatory, a research institution specializing in international tax matters, established in 2021.
    • This inaugural edition of the report is the result of collaborative efforts involving over 100 researchers from across the globe, working alongside tax authorities.
    • It represents the first systematic attempt to analyze available data in the field of taxation.

    Global Minimum Tax for MNCs

    • Established in October 2021 by 136 countries, including India, setting a 15% global minimum tax rate for MNCs.
    • Major economies are aiming to discourage multinational companies from shifting profits – and tax revenues – to low-tax countries regardless of where their sales are made.

     

    Tax Haven

    A tax haven is a foreign country or corporation used to avoid or reduce income taxes, especially by investors from another country. A tax haven is a country or place that has a low rate of tax so that people choose to live there or register companies there in order to avoid paying higher tax in their own countries.

    Key Findings of the GTE Report

    The report uncovers the following pivotal findings:

    • Reduction in Offshore Tax Evasion: Wealthy individuals’ offshore tax evasion has significantly declined over the past decade, primarily due to the automatic exchange of bank information, resulting in a three-fold reduction in evasion.
    • Profit Shifting to Tax Havens: MNCs shifted approximately $1 trillion to tax havens in 2022, accounting for 35% of their global profits. This has led to a substantial loss in global corporate tax revenues, impacting approximately 10% of total collections, with U.S. multinationals playing a prominent role.
    • Global Minimum Tax Impact: The expected positive impact of the 15% global minimum tax rate on MNCs has been weakened by various loopholes.
    • Low Taxation for Billionaires: Billionaires globally often experience effective tax rates ranging from 0% to 0.5% of their wealth, utilizing shell companies to evade income taxes.
    • Aggressive Tax Competition: New forms of aggressive tax competition have emerged, eroding government revenues and exacerbating inequality.

    Proposed solutions

    • Empowering ‘Automatic Exchange of Bank Information’: Launched in 2017 to combat offshore tax evasion by affluent individuals. Facilitated the sharing of deposit information with foreign tax authorities.
    • Global Minimum Tax on Billionaires: Proposes a 2% global minimum tax on billionaires, mirroring the model for MNCs, ensuring minimum tax rates for the wealthiest individuals.
    • Strengthening Global Minimum Tax for MNCs: Advocates for reinforcing the global minimum tax for MNCs while eliminating existing loopholes, potentially augmenting global corporate tax revenues by $250 billion annually.
    • Fair Allocation of Additional Revenues: Proposes mechanisms for equitable distribution of additional tax revenues generated by these measures among countries.

    Conclusion

    • The GTE report illuminates substantial progress in curbing tax evasion while underscoring persistent challenges and reform opportunities.
    • The proposed solutions aim to foster international collaboration in addressing tax-related issues and promoting fiscal equity on a global scale.
  • India’s record Food Production

    Food Production

    Central Idea

    • Recent data from the agriculture ministry has revealed that India achieved record-high food production in the 2022-23 fiscal year.
    • However, this surge in production appears to be at odds with the government’s decision to restrict the export of key staples like wheat and rice, as well as the persistent trend of rising food inflation.

    Food Production Statistics

    • Record-High Food Production: The agriculture ministry estimates food production for 2022-23 at a historic 329.7 million tonnes, marking a 4.5% increase from the previous year.
    • Cereal Production: Major cereal production, including rice and wheat, rose by 4.9% and 2.6%, respectively. Coarse grain production surged by 12%, while pulses production experienced a 4.4% year-on-year decline but remained 6% higher than the five-year average.
    • Challenges Faced: These estimations were made despite adverse conditions such as subpar monsoons affecting rice output and late rains causing damage during crop harvesting.

    Inconsistencies in the Data

    • Export Curbs: In September 2022, India imposed export curbs on broken rice and imposed a 20% duty on certain varieties due to expected domestic production challenges. These curbs have since intensified.
    • Wheat Export Ban: Last year, a miscalculation of wheat harvest, primarily due to a heatwave, led to export bans in May 2022, despite promises to bridge global supply gaps after Russia’s invasion of Ukraine.
    • Rising Food Prices: Despite record production and export restrictions, retail prices for cereals have continued to surge. Wheat and rice prices have been in double digits, with consumer cereal prices up by 11% year-on-year, and pulses registering a 16.4% increase. As of October 21, retail prices for rice and wheat flour were 12.7% and 5% higher year-on-year, respectively.

    Prospects for 2023-24

    • Kharif Production Estimate: The first advance estimate for kharif production, typically released in September, is yet to be published. This year’s monsoon, with the lowest rainfall in five years and uneven distribution, is expected to impact rice production, the main kharif crop.
    • Pulses and Oilseeds: Additionally, reduced rainfall in several states may affect pulses and oilseeds production. Retail prices for specific pulse varieties like tur (pigeon peas) have already surged by 38% compared to the previous year.

    Challenges in Robust Crop Estimations

    • Reliability of Data: National crop yield estimates rely on crop-cutting experiments conducted by state revenue and agriculture departments, raising concerns about the accuracy of data collection, particularly in understaffed state departments.
    • Remote Sensing: India is using remote sensing to cross-verify the data, yet reliability remains a challenge, especially for crops with multiple harvests.
    • Horticulture Crops: Estimating yield for horticulture crops, which are harvested in stages, is even more complex than for food grains.

    Conclusion

    • India’s agricultural landscape presents a perplexing scenario with record-high food production, export restrictions, and stubborn food inflation.
    • The government’s efforts to stabilize prices through export curbs have not yielded the expected results.
    • As India navigates the complexities of its agricultural sector, it must address the discrepancies in data collection and explore innovative approaches to ensure accurate estimates and sustainable food security.
  • The Indian Himalayan Region needs its own EIA

    What’s the news?

    • In light of the recent Teesta dam breach in Sikkim and floods in Himachal Pradesh, the potential negative impact of developmental activities on our ecology, especially in the mountains, is evident.

    Central idea

    • The recent Teesta dam breach in Sikkim and devastating floods and landslides in Himachal Pradesh have underscored the destructive consequences of our current development model. It is crucial to evaluate the environmental repercussions of significant human endeavors in order to strike a balance between development and ecological preservation.

    What is EIA?

    • Definition: EIA, or Environment Impact Assessment, is a process defined by the United Nations Environment Programme (UNEP) to gauge the environmental, social, and economic impacts of a project before implementation.
    • Functions: It contrasts various project alternatives, predicts environmental consequences, and suggests appropriate mitigation strategies.

    EIA’s Historical Development in India

    • 1976–77: A precursor to EIA began with an evaluation of river valley projects.
    • 1994: The Union Ministry of Environment, Forests, and Climate Change introduced the first EIA notification.
    • 2006: The 2006 notification decentralized the process, allowing states to issue EC (Environmental Clearance) in specific cases. This policy was later amended for refinement.
    • The 2020 draft EIA was criticized as favoring industries while neglecting ecological concerns.

    EIA 2006 Notification’s Scope and Limitations

    • It establishes the procedure for giving EC.
    • Only specific projects listed in the attached schedule require an EC.
    • It categorizes projects (e.g., mining, power generation). However, the threshold limits for requiring an EIA remain consistent nationwide.

    The Potential of EIA for Sustainable Development

    • Informed Decision-Making: EIA provides data for informed choices that balance development with environmental concerns.
    • Early Risk Identification: EIA identifies and mitigates potential environmental harm, promoting sustainable project designs.
    • Public Participation: EIA’s public consultations enhance transparency and inclusive decision-making.
    • Legal Framework: EIA is part of the legal framework for environmental protection, ensuring adherence to standards.
    • Long-Term Focus: EIA emphasizes long-term sustainability by assessing projects’ lasting impacts.

    Ignoring the Himalayan region

    • Inconsistency: Despite understanding the unique needs of the Indian Himalayan Region (IHR), its vulnerabilities aren’t addressed separately in the EIA.
    • Issue: Both the old and 2020 draft notifications don’t differentiate the IHR from the rest of India in terms of development needs.
    • Impact: This oversight results in the Himalayan States facing yearly devastation from extreme weather conditions.

    Flaws in the Graded Approach

    • The current approach differentiates risk based on location (e.g., reserved forest, national park). But the IHR, despite its ecological significance, is treated the same as other regions.

    Proposed Solutions

    • Differentiate environmental standards for projects in the IHR.
    • Address IHR-specific concerns at all EIA stages.
    • Include provisions about the IHR in general conditions for all projects.

    Existing Issues with the EIA

    • Lack of Oversight: There is no national regulator for transparent project appraisal and monitoring.
    • Reactive Nature: EIA currently reacts to proposals rather than preempting them.
    • Biased Assessments: Often, EIAs are in favor of projects because they’re funded by the project proponent.
    • Limited Scope: The current process doesn’t adequately consider the cumulative impacts of multiple projects in a region.

    Conclusion

    • The EIA process, especially concerning the IHR, requires a comprehensive review. Exploring tools like strategic environmental assessment can be more effective in addressing the cumulative impact of development in regions like the IHR. Policymakers should prioritize the environment and ecology in their developmental plans.
