Background
UPSC frequently examines challenges of urbanisation, disaster management, climate change impacts, and infrastructure resilience. This concept integrates these critical themes, offering a multi-dimensional perspective relevant for GS1, GS2, and GS3.
Urban flood resilience refers to the capacity of cities to withstand, adapt to, and recover from the impacts of extreme rainfall events, which are increasingly exacerbated by climate change and rapid, often unplanned, urbanisation. It encompasses robust infrastructure, effective governance, and community preparedness to minimise disruption and loss.
Facts & tables
- Climate Change Impact
- Erratic and intense monsoon rainfall patterns, undermining existing infrastructure design assumptions.
- Urbanisation Challenges
- Haphazard growth, concretisation, and reclamation of natural water bodies reduce water absorption and increase run-off.
- Infrastructure Deficiencies
- Inadequate drainage capacity, incomplete mitigation projects (e.g., BRIMSTOWAD), and lack of redundancies in critical services.
- Cascading Failures
- Heavy rainfall combined with high tides and infrastructure vulnerabilities leads to widespread disruption and compounded effects.

Which of the following statements in relation to NIRANTAR (National Institute for Research and Application of Natural Resources to Transform, Adapt and Build Resilience), a platform of institutions under the Ministry of Environment, Forest and Climate Change, is/are correct ?
1. Ecosystem Survey and Analysis is a vertical under this platform, the lead institute of which is Botanical Survey of India, Kolkata.
2. Research and Management of Ecosystem Service is a vertical under this platform, the lead institute of which is Central Zoo Authority, New Delhi.
3. Capacity Development Support is a vertical under this platform, the lead institute of which is Indian Institute of Forest Management, Bhopal.
Select the answer using the code given below :
Statement 1 is Correct: The National Institute for Research and Application of Natural Resources to Transform, Adapt and Build Resilience (NIRANTAR) is a collaborative platform under the Ministry of Environment, Forest and Climate Change (MoEFCC). Ecosystem Survey & Analysis is one of its four thematic verticals, and its lead institute is the Botanical Survey of India (BSI), Kolkata. Statement 2 is Incorrect: The Research and Management of Ecosystem Service vertical is led by the Indian Council of Forestry Research and Education (ICFRE), Dehradun, not the Central Zoo Authority (CZA). The CZA is merely a participating institute under this vertical. Statement 3 is Correct: The Capacity Development Support vertical focuses on research, education, and capacity building. The lead institute for this vertical is the Indian Institute of Forest Management (IIFM), Bhopal. Therefore, option B is the correct answer.
Consider the following statements:
Statement I:
At the 28th United Nations Climate Change Conference (COP28), India refrained from signing the “Declaration on Climate and Health”.
Statement II:
The COP28 Declaration on Climate and Health is a binding declaration; and if signed, it becomes mandatory to decarbonize health sector.
Statement III:
If India’s health sector is decarbonized, the resilience of its health-care system may be compromised.
Which one of the following is correct in respect of the above statements?
At COP28, India chose not to sign the “Declaration on Climate and Health,” and this decision can be understood by analyzing the nature of the declaration and India’s concerns. ✅ Statement I: Correct. India did not sign the COP28 Declaration on Climate and Health, unlike over 120 other countries. ❌ Statement II: Incorrect. The declaration is not legally binding; it is a voluntary political commitment. Signing it does not legally mandate countries to decarbonize their health sectors immediately. ✅Statement III: Correct. India’s concern is that rapid decarbonization of its health sector could compromise the resilience and accessibility of healthcare services, given current developmental challenges and resource constraints. Therefore, only Statement III correctly explains Statement I, while Statement II is factually wrong about the binding nature of the declaration.
Which organization has enacted the Nature Restoration Law (NRL) to tackle climate change and biodiversity loss?
✅ A. The European Union:
The Nature Restoration Law (NRL) is an EU legislative initiative adopted in 2024. It sets binding targets to restore ecosystems, fight climate change, and protect biodiversity across EU member states. ❌ B. The World Bank:
An international financial institution providing loans and grants; it does not enact laws like the NRL. ❌ C. OECD:
An organization promoting economic cooperation and policy coordination; it does not enact binding environmental laws such as the NRL. ❌ D. FAO:
A UN agency focused on hunger and agriculture; it does not enact regional laws like the NRL.
Consider the following statements with reference to India's response to climate change :
I. India's Long-Term Low Emission Development Strategy (LT-LEDS) is a crucial tool for achieving net-zero emissions by 2070.
II. India's 4th Biennial Update Report (BUR-4) submitted in December, 2024 recorded around 8% decrease in Greenhouse gas emissions in 2020 over 2019.
III. Climate-resilient development necessarily depends on quick and short-term achievement of emission reduction targets.
Which of the following relationships among the above statements is/are correct ?
1. Statement I is empirically supported by statement II.
2. Statement III contradicts the approach implicit in statement I.
3. Statement I and statement III together establish the premise of long-term sustainability.
Select the answer using the code given below :
Statement I is Correct: India's Long-Term Low Emission Development Strategy (LT-LEDS) is indeed a crucial tool for achieving net-zero emissions by 2070. It outlines the strategic framework necessary for sectoral transitions in energy, transport, industry, and forestry to meet this long-term goal. Statement II is Incorrect: While India's 4th Biennial Update Report (BUR-4) does record an approximately 8% decrease in greenhouse gas emissions in 2020 compared to 2019, this decrease is attributed to the economic slowdown and lockdowns during the COVID-19 pandemic, not to structural or strategic efforts towards long-term emission reductions. Therefore, it does not empirically support the strategic framework of LT-LEDS. Statement III is Correct: The IPCC emphasizes that climate-resilient development depends on rapid, deep, and immediate emission reductions in the short term. This approach can be seen as contradicting the long-term focus of strategies like LT-LEDS if they do not also incorporate aggressive short-term actions. Therefore, the correct relationship is that Statement III contradicts the approach implicit in Statement I, making option B correct.
Consider the following statements:
Statement I:
Article 6 of the Paris Agreement on climate change is frequently discussed in global discussions on sustainable development and climate change.
Statement II:
Article 6 of the Paris Agreement on climate change sets out the principles of carbon markets.
Statement III:
Article 6 of the Paris Agreement on climate change intends to promote inter-country non-market strategies to reach their climate targets.
Which one of the following is correct in respect of the above statements?
Article 6 of the Paris Agreement is crucial as it outlines international cooperation through both carbon markets and non-market approaches to help countries meet climate goals. ✅ Statement I is correct:
* Article 6 is widely discussed because it enables cooperation through market and non-market means to fight climate change. ✅ Statement II is correct:
* It defines rules for carbon markets, including carbon trading and credit mechanisms. ✅ Statement III is correct:
* It also promotes non-market tools like technology transfer and capacity building to reach climate targets. So, the correct answer is: A

Consider the following statements:
Statement-I: Carbon markets are likely to be one of the most widespread tools in the fight against climate change.
Statement-II: Carbon markets transfer resources from the private sector to the State.
Which one of the following is correct in respect of the above statements?
* Carbon markets, which include mechanisms like cap-and-trade systems and carbon offsets, are increasingly being used as a tool to incentivize emissions reductions and help in the fight against climate change. So, statement 1 is true. * Carbon markets typically work by transferring resources from emitters (usually in the private sector) to entities that can reduce or remove greenhouse gas emissions, which can be either private entities or the government. So, statement 2 can also be true.
Consider the following statements :
1. Under the Ramsar Convention, it is mandatory on the part of the Government of India to protect and conserve all the wetlands in the territory of India.
2. The Wetlands (Conservation and Management) Rules, 2010 were framed by the Government of India based on the recommendations of Ramsar Convention.
3. The Wetlands (Conservation and Management) Rules, 2010 also encompass the drainage area or catchment regions of the wetlands as determined by the authority.
Which of the statements given above is/are correct?
Statement 1 is incorrect. While the Ramsar Convention encourages member countries to take action for wetland conservation and wise use, there's no legal mandate to protect all wetlands. Statement 2 is incorrect. The Wetlands (Conservation and Management) Rules, 2010 were formulated by the Indian government to regulate activities in wetlands, and their development was not certainly influenced by the Ramsar Convention's principles. The rules also consider other national legislations and priorities. Statement 3 is correct. The Wetlands (Conservation and Management) Rules, 2010 do encompass the drainage area or catchment regions of the wetlands. This holistic approach recognizes the importance of the surrounding area for the overall health and functioning of the wetland ecosystem.
As per the Solid Waste Management Rules, 2016 in India, which one of the following statements is correct?
* Solid Waste Management Rules, 2016 mandate the segregation of waste into three categories - biodegradables, dry recyclables (plastic, paper, metal, etc.), and domestic hazardous waste (diapers, napkins, etc.). * The SWM Rules, 2016 apply not just to urban areas but also to urban local bodies, notified areas, census towns, all industrial townships, special economic zones, State and Central government organisations, places of pilgrimage, religious and historical importance. * There is no restriction on moving waste from one district to another. Waste generators can transport waste as needed for disposal, treatment, or processing. * Waste processing facilities will have to be set up by all local bodies having a population of 1 million or more within two years. * For census towns with a population below 1 million or all local bodies having a population of 0.5 million or more, common, or stand-alone sanitary landfills will have to be set up in three years. * Also, common, or regional sanitary landfills to be set up by all local bodies and census towns with a population under 0.5 million will have to be completed in three years.
