    In the context of mitigating the impending global warming due to anthropogenic emissions of carbon dioxide, which of the following can be the potential sites for carbon sequestration? 1. Abandoned and uneconomic coal seams 2. Depleted oil and gas reservoirs 3. Subterranean deep saline formations Select the correct answer using the code given below:

    1. A1 and 2 only
    2. B3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: D

    All three options (1, 2, and 3) can be potential sites for carbon sequestration

    Abandoned and uneconomic coal seams: These underground coal mines already have existing rock formations suitable for storing carbon dioxide. Since they are no longer operational, they can be repurposed for CO2 storage, potentially with the added benefit of enhancing methane capture from abandoned mines.

    Depleted oil and gas reservoirs: Once oil and gas reserves are depleted, they still have porous rock structures that can trap injected carbon dioxide. Repurposing these reservoirs for carbon storage leverages existing infrastructure and reduces the need for drilling new wells.

    Subterranean deep saline formations: Deep saline formations are layers of rock saturated with briny water, far below freshwater resources. Their geological properties allow for the storage of large volumes of carbon dioxide with minimal risk of leakage or contamination of freshwater sources.

    Due to some reasons if there is a huge fall in the population of species of butterflies, what could be its likely consequence/consequences? 1. Pollination of some plants could be adversely affected. 2. There could be a drastic increase in the fungal infections of some cultivated plants. 3. It could lead to a fall in the population of some species of wasps, spiders and birds. Select the correct answer using the code given below:

    1. A1 only
    2. B2 and 3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: C

    Statement 1 is correct: Butterflies are vital pollinators for many flowering plants. A decline in their population can lead to reduced pollination success, affecting fruit and seed production. This, in turn, can disrupt plant communities that rely on butterflies for pollination, potentially impacting entire ecosystems.

    Statement 2 is incorrect: While some butterfly species may interact with fungi, a decline in butterfly populations is unlikely to cause a drastic increase in fungal infections on cultivated plants. Factors like humidity, temperature, plant health, and fungicide use play a far more significant role in the spread of fungal diseases than butterfly populations.

    Statement 3 is correct: Butterflies are an essential part of the food web, serving as prey for wasps, spiders, birds, and other insectivorous species. A sharp decline in butterfly populations could negatively impact these predators, disrupting the ecological balance and potentially leading to cascading effects on biodiversity.

    Which of the following practices can help in water conservation in agriculture? 1. Reduced or zero tillage of the land 2. Applying gypsum before irrigating the field 3. Allowing crop residue to remain in the field Select the correct answer using the code given below :

    1. A1 and 2 only
    2. B3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: C

    Statement 1 is correct: Reduced or zero tillage of the land minimises soil disturbance, promoting better water retention. Less disturbed soil creates a more compact surface that reduces evaporation and allows rainwater to infiltrate deeper into the ground.

    Statement 2 is incorrect: Applying gypsum before irrigating the field Gypsum (calcium sulfate) is a soil amendment that can improve soil structure and drainage in some situations. However, it doesn't directly conserve water. In some cases, excessive gypsum application might even increase the leaching of nutrients and salts.

    Statement 3 is correct: Allowing crop residue to remain in the field Leaving crop residue on the soil surface acts like a mulch. This mulch helps suppress weeds, reduces soil erosion, and minimises water evaporation from the soil surface.

  4. With reference to ‘Global Climate Change Alliance’, which of the following statements is/are correct?…

It is coordinated by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). Select the correct answer using the code given below:

    1. A1 and 2 only
    2. B3 only
    3. C2 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: A

    Statement 1 is correct: The GCCA was established by the European Union to enhance climate cooperation with developing nations, particularly Least Developed Countries (LDCs) and Small Island Developing States (SIDS).

    Statement 2 is correct: A core objective of the GCCA is to provide technical and financial assistance to developing countries, helping them integrate climate change adaptation and mitigation into their national policies, development strategies, and budgets.

    Statement 3 is incorrect: The GCCA is coordinated by the European Commission through its established political dialogue and cooperation mechanisms. It is not managed by the World Resources Institute (WRI) or the World Business Council for Sustainable Development (WBCSD).

    4. DKuno Palpur Wildlife Sanctuary
    Answer and explanation

    Correct answer: D

    An environment ministry's expert committee approved Kuno Palpur in Madhya Pradesh as the second home for Asiatic lions found only in Gir National Park. However, the Gujarat government will not share lions unless 33 studies as mandated by the International Wildlife Watchdog IUCN is completed.

  6. In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique?…

    In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique? 1. It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature. 2. Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms. 3. Genetic engineering can be used to create microorganisms specifically designed for bioremediation. Select the correct answer using the code given below:

    1. A1 only
    2. B2 and 3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: C

    Bioremediation is a technique that utilizes living organisms, primarily microorganisms like bacteria and fungi, to remove or neutralize contaminants from polluted environments. It essentially harnesses and accelerates natural biodegradation processes for environmental cleanup.

    Statement 1 (correct): This accurately describes a key advantage of bioremediation. It leverages and accelerates natural biodegradation processes by introducing suitable microorganisms or optimizing environmental conditions.

    Statement 2 (incorrect): Bioremediation can be effective for many contaminants but not all. Heavy metals like cadmium and lead are often not readily broken down or removed completely. They might be transformed or immobilized, but not necessarily eliminated.

    Statement 3 (correct): Genetic engineering offers a promising approach for developing microorganisms with enhanced capabilities for bioremediation. These engineered microbes can target specific pollutants or work more efficiently in challenging environments.

  11. In India, if a species of tortoise is declared protected under Schedule I of…

    In India, if a species of tortoise is declared protected under Schedule I of the Wildlife (Protection) Act, 1972, what does it imply?

    1. AIt enjoys the same level of protection as the tiger.
    2. BIt no longer exists in the wild, a few individuals are under captive protection, and now it is impossible to prevent its extinction.
    3. CIt is endemic to a particular region of India.
    4. DBoth b and c stated above are correct in this context.
    Answer and explanation

    Correct answer: A

    Schedule I of the Wildlife (Protection) Act, 1972, provides the highest level of legal protection for wildlife in India. Species listed under this Schedule, such as the Tiger, are protected from hunting and trade, with violations attracting the most stringent penalties. Therefore, any species of tortoise listed in Schedule I enjoys the same legal safeguards as the tiger.

    Option B is incorrect as it describes the 'Extinct in the Wild' category of the IUCN Red List, which is a biological conservation status rather than a legal designation under the WPA. Option C is incorrect because endemism refers to a species being restricted to a specific geographic location; while many Schedule I species may be endemic, the listing itself is based on the degree of threat and the requirement for absolute protection rather than geographic range.

    Note: The original Wildlife (Protection) Act, 1972, contained six schedules (I-IV for animals, V for vermin, and VI for plants). The Wildlife (Protection) Amendment Act, 2022, has since rationalized these into four schedules, but the principle of Schedule I providing the highest protection remains unchanged.

    1. A1 and 2 only
    2. B3 only
    3. C2 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: D

    Reducing Emissions from Deforestation and Forest Degradation (REDD) attempts to create financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development.

    REDD goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. REDD has the potential to simultaneously contribute to climate change mitigation and poverty alleviation, whilst also conserving biodiversity and sustaining vital ecosystem services.

    Protection of biodiversity: Forests are incredibly diverse ecosystems, and protecting them through REDD initiatives helps safeguard countless species of plants and animals. Resilience of forest ecosystems: By reducing deforestation and degradation, REDD helps maintain healthy forests that can better withstand natural disturbances like droughts, floods, and pests. Poverty reduction: Many forest communities rely on forests for their livelihoods. REDD programs can provide financial incentives for sustainable forest management, creating income opportunities and alleviating poverty.

    Therefore, the correct answer is 1, 2 and 3.

    'Gadgil Committee Report' and 'Kasturirangan Committee Report', sometimes seen in the news, are related to -

    1. AConstitutional reforms
    2. BGanga Action Plan
    3. CLinking of rivers
    4. DProtection of Western Ghats
    Answer and explanation

    Correct answer: D

    The Gadgil Committee Report and the Kasturirangan Committee Report both focus on the conservation of the Western Ghats, one of the world's eight "hottest" biodiversity hotspots.

    Gadgil Committee Report (2011) Formally known as the Western Ghats Ecology Expert Panel (WGEEP) Report, this report advocated for strict environmental protection measures across the entire Western Ghats. It recommended designating the entire region as an Ecologically Sensitive Area (ESA), divided into three zones with graded levels of regulation on development activities such as mining, construction, and deforestation. The report emphasized grassroots participation and sustainable development, but its stringent recommendations faced resistance from state governments and industries.

    Kasturirangan Committee Report (2012) To review the Gadgil Committee's recommendations, the High-Level Working Group (HLWG), led by Dr. Kasturirangan, was formed. This report sought a balance between conservation and development by proposing that only 37% of the Western Ghats be designated as ESA, focusing primarily on forest and uninhabited regions while allowing regulated development in other areas. It adopted a more lenient approach than the Gadgil Report, leading to criticism from environmentalists who argued that it diluted the conservation efforts.

    In summary, while the Gadgil Report advocated for comprehensive protection with stringent regulations, the Kasturirangan Report took a more moderate stance, allowing some developmental activities while still acknowledging the ecological importance of the Western Ghats.

    2. B3 only
    3. C1 and 3 only
    4. DNone of the above is an advantage of practising drip irrigation
    Answer and explanation

    Correct answer: C

    Drip irrigation is an efficient water delivery system that applies water directly to the roots of plants through a network of tubes, emitters, and valves. It is widely used to conserve water, improve crop yields, and prevent soil degradation.

    ![Drop Irrigation](https://d39jluplm5thpx.cloudfront.net//Drip_Irrigation_d262f8fa0f.png)

    Statement 1 is correct: Drip irrigation delivers water precisely at the plant's root zone, reducing the moisture available on the soil surface. Since weeds typically thrive in moist topsoil, limiting water exposure to non-target areas helps suppress their growth. This makes weed control easier compared to traditional irrigation methods like flooding or sprinklers, which wet the entire field.

    Statement 2 is incorrect: Soil salinity refers to the accumulation of salts in the soil, which can hinder plant growth. While drip irrigation helps manage water efficiently, it does not directly reduce salinity. However, it can be combined with strategic flushing techniques (applying extra water at intervals) to push salts below the root zone, preventing salt buildup in the upper soil layers.

    Statement 3 is correct: Drip irrigation releases water slowly and in a controlled manner, reducing surface runoff that can lead to soil erosion. Unlike traditional flood irrigation, which can wash away the topsoil, drip irrigation preserves soil structure and fertility, making it a sustainable choice for agriculture. Hence, the correct answer is option C.

    1. A1 only
    2. B2 and 3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: C

    The United Nations Convention to Combat Desertification (UNCCD) was established in 1994 and is the sole legally binding international agreement linking environment and development to sustainable land management.

    Statement 1 is correct: The UNCCD aims to promote effective action through innovative national programmes and supportive international partnerships. It provides a framework for countries to work together to combat desertification and mitigate the effects of drought.

    Statement 2 is incorrect: The Convention has a particular focus on Africa, not South Asia and North Africa. In fact, its full name is the 'United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa'. Furthermore, the Secretariat does not facilitate the allocation of the 'major portion' of financial resources; financial mobilization is primarily handled through the Global Mechanism and the Global Environment Facility (GEF).

    Statement 3 is correct: The UNCCD is unique among the Rio Conventions for its commitment to a bottom-up approach. It emphasizes the participation of local communities, land users, and non-governmental organizations in the design and implementation of programmes to combat land degradation.

    The FAO accords the status of 'Globally Important Agricultural Heritage Systems (GIAHS)' to traditional agricultural systems. What is the overall goal of this initiative? 1. To provide modern technology, training in modern farming methods and financial support to local communities of identified GIAHS so as to greatly enhance their agricultural productivity 2. To identify and safeguard eco-friendly traditional farm practices and their associated landscapes, agricultural biodiversity and knowledge systems of the local communities 3. To provide Geographical Indication status to all the varieties of agricultural produce in such identified GIAHS Select the correct answer using the code given below.

    1. A1 and 3 only
    2. B2 only
    3. C2 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: B

    The Globally Important Agricultural Heritage Systems (GIAHS) initiative was launched by the Food and Agriculture Organization (FAO) in 2002 to identify, safeguard, and promote traditional agricultural systems that have historical, cultural, environmental, and social significance. These systems demonstrate sustainable agricultural practices, rich biodiversity, and resilient rural livelihoods while maintaining a harmonious relationship with nature.

    Statement 1 is incorrect: The GIAHS program is not primarily aimed at increasing agricultural productivity through modern methods. Instead, it focuses on preserving traditional farming practices, indigenous knowledge, and sustainable land-use systems that have evolved over centuries. While some modern improvements might be integrated to support local livelihoods, the core emphasis is conservation, not productivity enhancement.

    Statement 2 is correct: The primary goal of GIAHS is to identify and protect unique agricultural systems that are vital for global biodiversity, cultural heritage, and food security. This includes preserving traditional landscapes, indigenous crops, and local community knowledge, ensuring their sustainability for future generations.

    Statement 3 is incorrect: While some GIAHS products might qualify for Geographical Indication status, it's not an automatic benefit. GI status is granted based on specific criteria related to a product's origin, traditional production techniques, and unique qualities, which require a separate legal recognition process. Hence, the correct answer is option B. 2 only.

    The term 'Intended Nationally Determined Contribution' is sometimes seen in the news in the context of:

    1. APledge made by the European countries to rehabilitate refugees from the war-affected Middle East.
    2. BPlan of action outlined by the countries of the world to combat climate change.
    3. CCapital contributed by the member countries in the establishment of the Asian Infrastructure Investment Bank.
    4. DPlan of action outlined by the countries of the world regarding Sustainable Development Goals.
    Answer and explanation

    Correct answer: B

    The Intended Nationally Determined Contributions (INDCs) were submitted by countries before the Paris Agreement (2015) as their initial climate action plans to combat climate change. These documents outlined how each country intended to contribute to global efforts in reducing greenhouse gas (GHG) emissions and adapting to climate impacts.

    These were preliminary pledges, meaning they were not legally binding commitments but rather expressions of intent.

    Each country independently decided its contribution based on its capabilities, national circumstances, and priorities. Unlike top-down approaches in past climate treaties, INDCs followed a bottom-up approach.

    The plans outlined specific measures countries intended to take to reduce greenhouse gas emissions, increase renewable energy use, improve energy efficiency, and adapt to climate change impacts.

The Agreement was signed by all the member countries of the UN and it will go into effect in 2017. 2. The Agreement aims to limit greenhouse gas emissions so that the rise in average global temperature by the end of this century does not exceed 2 degrees C or even 1.5 degrees C above pre-industrial levels. 3. Developed countries acknowledged their historical responsibility in global warming and committed to donate $1000 billion a year from 2020 to help developing countries to cope with climate change. Select the correct answer using the code given below.

    1. A1 and 3 only
    2. B2 only
    3. C2 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: B

    Statement 1 is incorrect: The agreement did not "go into effect in 2017." It was adopted in Dec 2015, signed in April 2016, and legally entered into force on November 4, 2016, after the "55/55" threshold (55 countries representing 55% of global emissions) was met.

    Statement 2 is correct: This is the core "temperature goal" of the Paris Agreement: keeping the increase well below 2°C and pursuing efforts to limit it to 1.5°C above pre-industrial levels.

    Statement 3 is incorrect: While the agreement acknowledges "Common But Differentiated Responsibilities" (CBDR), the financial commitment was $100 billion per year by 2020, not $1000 billion.
