UGC NET Questions (Paper – 1)

Statements A, B and D are correct and reflect the objectives and principles of climate finance and technology transfer. Climate finance supports mitigation and adaptation, technology transfer promotes access to clean technologies and equity considerations such as common but differentiated responsibilities shape negotiations. Statements C and E are incorrect because adaptation also needs finance and the private sector plays a significant role in providing funds and investments. Thus, the combination A, B and D only is the correct answer.

Option A:
Option A is correct as it brings together the three statements that align with the design of climate regimes and excludes those that restrict finance to mitigation or deny private sector roles. It acknowledges both the public and private dimensions and the equity principles embedded in climate agreements.

Option B:
Option B is incorrect because it adds statement E, which falsely claims that private sector investment has no role in climate finance. In practice, many climate funds and mechanisms explicitly aim to leverage private capital, so including E makes the option wrong.

Option C:
Option C is incorrect as it includes statement C, which wrongly restricts finance to mitigation. Adaptation, particularly in vulnerable countries, also requires substantial financial support, so accepting C contradicts the broad mandate of climate finance.

Option D:
Option D is incorrect because it claims that all five statements are correct, thereby accepting both C and E. Doing so would ignore the adaptation dimension and the well-documented role of private investment.

Option E is incorrect as it groups B, D and E together. While B and D are correct, E is not, and the presence of this false statement invalidates the combination even though it contains two correct elements.

Option F is incorrect because it is composed entirely of statements C, D and E, among which only D is correct. Statements C and E misrepresent the scope of climate finance and the actors involved, so this option cannot be accepted.

Statements A, B, D and E are correct as they describe essential elements of participatory environmental governance. Hearings and access to information enable communities to voice concerns, involving them enhances quality and legitimacy, and marginalised groups may require special measures to participate. Statement C is false because participation does not guarantee that all demands are fully accepted, and F is false since participation is also relevant for policies, plans and programmes. Therefore, the correct set is A, B, D and E only.

Option A:
Option A is correct since it collects the four statements that reflect widely accepted principles of participation and excludes those that overpromise or unduly restrict its scope. It captures both procedural and equity concerns in participation.

Option B:
Option B is incorrect because it includes F, which wrongly limits participation to projects and ignores its role in broader policy and planning processes. This contradicts integrated environmental governance frameworks.

Option C:
Option C is incorrect as it also accepts F and omits A. Leaving out A ignores a core participatory mechanism—public hearings—while retaining an inaccurate restriction on where participation applies.

Option D:
Option D is incorrect because it again includes F and omits B, thereby underplaying the importance of information access while keeping a false limitation on participation arenas.

The Kyoto Protocol is a key international treaty under the UNFCCC that sets legally binding emission reduction targets for developed countries. Adopted in 1997 in Kyoto,Japan,it marked the first major step toward quantified greenhouse gas limits. It also introduced mechanisms such as emissions trading and the Clean Development Mechanism. Thus the description in the question clearly refers to the Kyoto Protocol.

Option A:
The Montreal Protocol focuses on phasing out ozone depleting substances such as CFCs. Its primary objective is protection of the ozone layer,not greenhouse gas reduction commitments for industrialised nations. Therefore it does not fit the description in the stem.

Option B:
The Basel Convention regulates transboundary movement and disposal of hazardous wastes. It is concerned mainly with waste management rather than climate change mitigation. Hence it is not the agreement described in the question.

Option C:
The Kyoto Protocol specifically addresses greenhouse gas emissions from developed countries. It sets quantified limits and timetables and establishes flexible mechanisms to achieve them. This makes it the correct answer for the treaty mentioned.

Option D:
The Stockholm Declaration emerged from the 1972 UN Conference on the Human Environment as a set of principles. It does not itself establish binding emission reduction targets. Therefore it does not correspond to the agreement described in the question.

Hazardous wastes are defined not simply by volume but by their dangerous properties. Wastes that are toxic, corrosive, flammable or chemically reactive can injure people, damage ecosystems and contaminate air, water or soil. Regulatory definitions often list these characteristics as criteria for special handling and disposal. Therefore, the option that mentions these properties and associated risks correctly describes what makes a waste hazardous.

Option A:
Option A is correct because it reflects how environmental regulations identify wastes that need stringent management. Such wastes may require special treatment, containment and monitoring to prevent accidents and long-term exposure.

Option B:
Option B is incorrect as inert bulky wastes like certain construction materials may pose disposal challenges but are not inherently hazardous in the toxic sense. They usually do not require the same level of control as hazardous wastes.

Option C:
Option C is incorrect because biodegradable kitchen scraps are generally considered non-hazardous municipal solid waste. They can often be composted safely under proper conditions.

Option D:
Option D is incorrect since debris like bricks and stones is typically inert and handled as construction and demolition waste. While it may cause physical space problems, it does not fit the hazardous waste category based on toxicity or reactivity.

Water reuse means employing treated wastewater as a resource for beneficial uses,instead of discharging it directly into the environment. This reduces freshwater demand and pollution simultaneously. The stem describes using treated wastewater for irrigation or landscaping,which is a classic case of water reuse. Hence Option C is correct.

Option A:
Depletion refers to reducing the stock of a resource irreversibly. Using treated wastewater does not deplete water but actually conserves freshwater,so Option A is wrong.

Option B:
Mining water would imply extracting water from deep or fossil sources. It does not describe circulation of treated wastewater back into productive uses.

Option C:
Reuse involves giving water a second life in new applications after adequate treatment. It aligns perfectly with the practice highlighted in the question stem.

Option D:
Withdrawal refers to taking water from a natural source like a river or aquifer. The question focuses on using already collected and treated wastewater,so Option D is not appropriate.

Statements A, B, C and E are correct as they summarise the pillars of the Sendai Framework, the need for integration into development, local participation and ecosystem-based measures. Statement D is false because early warning without preparedness, capacity or structural measures cannot eliminate risk. Statement F is false since risk depends on the interaction of hazard, exposure and vulnerability. Therefore, the correct combination is A, B, C and E only.

Option A:
Option A is incorrect because it omits E and thus ignores ecosystem-based approaches like mangrove belts, which are now widely recognised in disaster risk reduction strategies.

Option B:
Option B is incorrect as it includes F, which wrongly states that exposure and vulnerability are irrelevant, contradicting the standard risk formula.

Option C:
Option C is incorrect since it excludes A and therefore does not mention the global Sendai Framework, which is an important reference for policy.

Option D:
Option D is correct because it includes the core elements of contemporary DRR thinking and rejects statements that overstate the sufficiency of warnings or treat hazards as the only determinant of risk.

Slums are characterised by overcrowding,insecure tenure and inadequate access to basic services like water and sanitation. They emerge when urbanisation outpaces formal housing and infrastructure provision. The stem’s description of unplanned settlements lacking basic services corresponds directly to slums. Therefore this is the correct term.

Option A:
Suburbs are residential areas on the outskirts of cities,which may have good infrastructure and planned layouts. They are not defined by lack of services or informality,so they do not match the conditions described in the question.

Option B:
Gated communities are typically well planned residential enclaves designed for higher income groups. They usually have better than average access to services and security,which is the opposite of what the stem indicates.

Option C:
Slums are often situated on marginal lands and can be highly vulnerable to environmental hazards such as floods and landslides. Their growth reflects both urban poverty and inadequate planning,exactly as the question suggests.

Option D:
Exurbs are low density settlements beyond the suburbs,often inhabited by commuters. They are not necessarily informal or service deprived,so this term does not fit the scenario in the stem.

The updated NDC notes that India will put forward and propagate a healthy and sustainable way of living based on traditions of conservation and moderation, including through a mass movement for LiFE. This formally integrates lifestyle change into the country’s climate strategy. It signals that citizens’ choices, not just technology and policy, are important for meeting global climate goals. (NITI Aayog)

Option A:
This option is wrong because the NDC does not dismiss behaviour; it explicitly recognises sustainable lifestyles as a pillar of climate action.

Option B:
This option correctly summarises how LiFE is mentioned in the updated NDC and shows how people-centric strategies are woven into formal international commitments.

Option C:
A blanket ban on personal vehicles is not part of the NDC; instead, the focus is on nudging cleaner and more efficient mobility choices.

Option D:
The NDC does not say that only technological solutions will be used; it combines technology, policy, finance and lifestyle measures in an integrated approach.

Statements A, B, C, D and F are correct and explain definitions of the three Rs, their role in shifting towards a circular economy and the need for awareness and infrastructure. Statement E is false because reducing, reusing and recycling generally conserve energy and lower greenhouse gas emissions compared to producing from virgin materials. Therefore, the correct combination is A, B, C, D and F only.

Option A:
Option A is correct since it captures all true statements and excludes only E, which wrongly denies energy and climate benefits of 3R actions.

Option B:
Option B is incorrect because it omits D and F, ignoring the circular economy shift and the enabling role of awareness/infrastructure.

Option C:
Option C is incorrect as it includes E, which is false.

Option D:
Option D is incorrect because it omits B (reuse), so it does not represent the full 3R framework.

Energy efficiency means using less energy to provide the same or better level of service,for example through LED bulbs or well insulated buildings. It reduces energy bills and emissions simultaneously. The stem explicitly refers to maintaining the same level of service with less energy input,which is the core definition of energy efficiency. Therefore Option A is correct.

Option A:
Improving energy efficiency can be achieved through technological upgrades,maintenance and behavioural changes. It is often considered the lowest cost option for reducing greenhouse gas emissions. These characteristics match the description given in the question.

Option B:
Energy scarcity describes a situation where energy resources are insufficient to meet demand. It is a structural condition,not a measure of how effectively energy is used,so it does not suit the stem.

Option C:
Energy mining refers to extracting energy resources such as coal or uranium from the ground. It increases supply rather than making use more efficient,so it is not relevant here.

Option D:
Energy pricing relates to the tariff structure and cost of energy for consumers. While it can influence efficiency behaviour,it is not itself the process of delivering the same service with less energy.

Policy analyses explain that banning low-utility, high-litter items addresses the worst offenders in terms of environmental harm. At the same time, raising thickness standards for some remaining plastics is intended to encourage reuse and make collection and recycling easier. Together, these measures move the system gradually towards reduced disposability and more circular designs. They exemplify how regulatory mixes can balance practicality with environmental ambition in a large developing economy.

Option A:
This option correctly interprets the policy mix as targeting unnecessary items while improving the design of others to support reuse and circularity. It recognises the nuanced approach rather than an all-or-nothing ban.

Option B:
This option is incorrect because the government has not attempted to eliminate all plastics within a year; many essential and regulated uses remain. A sudden total ban would be neither practical nor reflected in the rules.

Option C:
Increasing waste generation is the opposite of the policy’s purpose. The measures aim to reduce litter and total plastic usage, while making remaining items more sustainable.

Option D:
The ban and related standards apply to domestically used items and do not revolve primarily around import–domestic distinctions. The focus is on product characteristics and environmental impact.

Disaster risk arises when a potentially damaging physical event interacts with vulnerable people, infrastructure and ecosystems. A strong hazard in an uninhabited area may not create a disaster, whereas a moderate hazard in a very vulnerable community can be devastating. Therefore, risk is commonly conceptualised as a function or product of hazard and vulnerability, with exposure explicitly considered in many formulations.

Option A:
Option A is incorrect because hazard alone does not determine risk; context and vulnerability matter greatly.

Option B:
Option B is incorrect since vulnerability without a triggering hazard does not lead to a disaster.

Option C:
Option C is correct as it captures the widely used risk equation linking hazard, vulnerability and exposure.

Option D:
Option D is incorrect; early warning and participation reduce risk, but they are not the definition of risk itself.

Natural increase refers to the population change obtained by subtracting the crude death rate from the crude birth rate. It deliberately excludes migration and focuses solely on natural demographic processes. Because the stem specifies population change due only to births and deaths, natural increase is the correct term. This measure helps compare growth trends across countries independent of migration flows.

Option A:
Net migration captures the balance between immigration and emigration rather than births and deaths. It is an important component of total population change but not the natural component referred to in the question. Hence it is not suitable for the blank.

Option B:
Total fertility represents the average number of children a woman is expected to have over her reproductive life. It is a measure of fertility behaviour, not a direct indicator of overall population change in a given year. Therefore it cannot replace natural increase in the stem.

Option C:
Natural increase isolates the effect of reproductive and mortality patterns on population growth. When it is positive, population grows even in the absence of migration; when negative, population shrinks. This makes it exactly the concept being described in the question.

Option D:
Population momentum refers to continued population growth for some time even after fertility has fallen to replacement level, due to the age structure of the population. It is a different phenomenon and does not describe the simple births minus deaths calculation in the stem.

Statements B, C and D are correct because they show that food security is influenced by climate impacts, sustainable practices and multiple dimensions beyond sheer output. Climate extremes affect yields, sustainable agriculture balances productivity and environmental health and food security includes access and nutrition. Statement A is incorrect since national production alone does not guarantee that people can access or afford adequate, nutritious food. Therefore, the combination that includes B, C and D and excludes A is the correct answer.

Option A:
Option A is incorrect because it leaves out D, which correctly emphasises access and nutritional quality as core components of food security. Restricting the concept to production and climate-impacted yields fails to capture the full meaning of food security.

Option B:
Option B is incorrect as it adds statement A, which wrongly claims that only total national production matters. By including A, this option accepts a narrow and misleading view of food security that ignores distribution and affordability issues.

Option C:
Option C is incorrect because it declares all four statements A, B, C and D to be correct. Since A is clearly false in light of the multidimensional definition of food security, this combination cannot be accepted.

Option D:
Option D is correct because it lists exactly those statements that align with widely accepted definitions of food security and environmental sustainability. It highlights climate effects, sustainable agricultural responses and the multi-dimensional nature of security, while rejecting the simplistic production-only view in A.

The Chipko movement emerged when villagers,especially women,physically embraced trees to stop commercial logging in their forests. Their main objective was to prevent the felling of trees and resulting deforestation. The stem directly mentions hugging trees to prevent an activity,which clearly refers to deforestation. Thus Option A correctly captures the focus of the movement.

Option A:
Deforestation threatens soil stability,water availability and local livelihoods in mountain regions. Chipko activists highlighted these dangers and demanded community rights over forests.

Option B:
Urbanisation is the growth of towns and cities and was not the direct target of Chipko protests,which focused on forest logging.

Option C:
Coal mining is a different environmental issue; Chipko is historically linked with stopping tree felling in Himalayan forests.

Option D:
River pollution is important but Chipko is chiefly associated with forest conservation via preventing logging,not river pollution campaigns.
