UGC NET Questions (Paper – 1)

The 30×30 target calls for conserving at least 30% of terrestrial, inland water and marine areas by 2030 through well-managed and connected systems of protected and conserved areas. It seeks not just numerical coverage but ecological representation and respect for Indigenous and local community rights. Achieving this is considered crucial for halting biodiversity loss and maintaining ecosystem services that support human well-being. (UNEP - UN Environment Programme)

Option A:
This option correctly states the content of the 30×30 pledge, emphasising both area and ecological quality.

Option B:
This option is incorrect; the framework does not prescribe demographic targets and focuses on changing production, consumption and land-use patterns instead.

Option C:
The framework does not require a fixed budget percentage for forestry alone; finance is to be mobilised across diverse conservation actions and ecosystems.

Option D:
The target is broader than tree planting and stresses appropriate conservation of varied ecosystems, not just planting trees in arbitrary locations.

By highlighting interdependence, the AR6 Synthesis Report argues that policies on climate, nature and development cannot be treated in isolation. For example, mitigation measures that also protect ecosystems can support livelihoods and reduce disaster risks, while poorly designed actions can create new vulnerabilities. The report stresses that integrated solutions and just transitions are needed to achieve the Sustainable Development Goals in a warming world. This perspective directly links global environmental change with everyday development choices for people, particularly the most vulnerable. (ipcc.ch)

Option A:
This option is incorrect because the report explicitly warns against siloed approaches, showing that climate, ecosystems and societies influence each other. Treating them separately risks ineffective or harmful policies.

Option B:
This option correctly captures the implication that climate, biodiversity and development policies should be aligned to create co-benefits. It emphasises equity and the need to protect vulnerable communities, which are central themes in the AR6 Synthesis Report.

Option C:
This option misrepresents the evidence, which shows that well-designed conservation and climate actions can support poverty reduction, for instance through resilient livelihoods and reduced disaster risks.

Option D:
Equity and justice are explicitly discussed in the IPCC reports, including issues such as loss and damage, adaptation gaps and distributional impacts. Claiming that equity lies outside climate policy contradicts these discussions.

Statements A, B, D and E are correct on integration, SDG 13, SDG 12 and partnerships. Statement C is wrong because many other SDGs include environmental targets. Statement F is wrong because monitoring is essential. Therefore A, B, D and E only is correct.

Option A:
Option A is correct and excludes C and F.

Option B:
Option B is incorrect because it includes C (false).

Option C:
Option C is incorrect because it includes F (false) and omits A.

Option D:
Option D is incorrect because it includes F (false) and omits B.

The phrase “tragedy of the commons” describes how rational actions by individuals using a shared resource can collectively lead to its collapse. A common pasture used by many herders is the classic example. The stem explicitly refers to overexploitation of a shared pasture,which matches the commons situation. Therefore “commons” is the correct word to fill the blank.

Option A:
The village is a social unit that may include both private and common resources. Overuse is not inevitable for everything in the village,so this term is too broad and does not capture the resource focus.

Option B:
Farmers are the users but they are not the resource being degraded. The tragedy arises from how they interact with the commons,so naming the users does not complete the conceptual phrase.

Option C:
Commons refers to resources that are rivalrous but difficult to exclude people from,such as grazing lands, fisheries and groundwater. This aligns perfectly with the shared pasture described in the question.

Option D:
Soil is one component of the pasture that may degrade,but the established term in environmental economics and politics is “tragedy of the commons,”not tragedy of the soil.

Acid rain forms when sulphur dioxide and nitrogen oxides released from combustion processes react with water vapour and oxidants in the atmosphere. These reactions produce sulphuric and nitric acids that are deposited as wet or dry precipitation. The resulting acidic deposition damages forests, aquatic ecosystems, soils and built structures. Therefore, the pairing of sulphur dioxide and nitrogen oxides is recognised as the principal cause of acid rain.

Option A:
Option A is incorrect because carbon monoxide and ozone play different roles in air pollution. Carbon monoxide is a toxic gas affecting human health, and ground-level ozone is a component of photochemical smog, but they are not the main precursors of strong acids in rainwater. Their chemistry does not primarily create acidic precipitation.

Option B:
Option B correctly names the gases that transform into sulphuric and nitric acids when they dissolve in cloud droplets. These gases are emitted largely from coal-based power plants, industrial boilers and vehicles, and controlling them is central to acid rain mitigation strategies.

Option C:
Option C is incorrect since methane is more associated with greenhouse effects, and chlorofluorocarbons are linked to ozone depletion and climate forcing. Neither group is directly responsible for the formation of the strong acids that cause acid rain in most regions.

Option D:
Option D is incorrect because hydrogen and helium are light gases that do not form acidic compounds in the atmosphere under normal environmental conditions. They are not significant contributors to rain chemistry or ecosystem acidification.

Statements A, B, C and E present a coherent picture of how industry relates to environment and sustainable development. Industrialisation can support growth and jobs, but pollution risks arise without safeguards, making cleaner technologies and resource efficiency important. Public disclosure of performance can create reputational incentives to improve compliance. Statements D and F are incorrect because regulations can drive innovation and environmental management systems explicitly support sustainable development goals. Therefore, the combination that includes A, B, C and E only is correct.

Option A:
Option A is correct because it selects all and only the statements that are conceptually sound: A and B describe growth and pollution risks, C stresses cleaner processes and E highlights disclosure as a driver of better performance. It appropriately excludes D, which overstates negative effects of regulation, and F, which ignores SDG linkages. This option aligns with contemporary views on industrial sustainability.

Option B:
Option B is incorrect as it omits statement E, thereby ignoring the role of transparency and public reporting in improving environmental behaviour. While A, B and C are true, leaving out E means the answer set is incomplete. In addition, it does nothing to correct the false notions in D and F.

Option C:
Option C is incorrect because it includes B, C and E but also F, which wrongly claims that environmental management systems are unrelated to SDGs. It also omits statement A, which correctly notes the economic aspect of industrialisation. The presence of F makes this combination logically flawed.

Option D:
Option D is incorrect since it brings together A, C and E with F. Although A, C and E are correct, including F introduces a clearly false statement about the irrelevance of environmental management systems to sustainable development. It also excludes B, which properly recognises pollution risks from poorly regulated industry.

Statements A, C and D correctly describe multiple ecosystem services of urban green spaces. Vegetation can reduce heat island effects, enhance air quality, provide habitats and extend greenery through roofs and walls. Statement B is incorrect because urban green spaces are recognised for supporting mental health, recreation and social interaction. Hence the combination that includes A, C and D while excluding B is the correct answer.

Option A:
Option A is incorrect because it includes only A and C and leaves out statement D. While A and C are true, D is also a correct statement about green roofs and walls contributing to urban greening and climate adaptation. Omitting a true statement makes this option incomplete.

Option B:
Option B is incorrect because it treats B as correct along with A and C. Statement B wrongly denies the psychological and recreational benefits of green spaces, which are well documented in urban planning and public health literature. Including this false statement invalidates the option.

Option C:
Option C is correct because it groups exactly the three accurate statements A, C and D and excludes the one false statement B. It reflects a rounded understanding of how urban green infrastructure contributes to cooling, air quality and biodiversity as well as innovative building-level greening.

Option D:
Option D is incorrect because it accepts B, C and D. The presence of B, which incorrectly claims no role of green spaces in mental health and recreation, makes the overall combination wrong even though C and D are true.

Among greenhouse gases emitted by human activities, carbon dioxide contributes the most to anthropogenic global warming in terms of total radiative forcing. It is released mainly from burning fossil fuels, deforestation and industrial processes. Although other gases like methane and nitrous oxide have higher warming potential per molecule, their concentrations and total forcing are lower. Hence, carbon dioxide is regarded as the primary driver of the enhanced greenhouse effect, making option D correct.

Option A:
Option A, nitrous oxide, is a potent greenhouse gas but its atmospheric concentration and total contribution to warming are smaller compared to carbon dioxide. It is significant in agriculture and industry, yet not the largest contributor overall.

Option B:
Option B, methane, has a higher global warming potential than carbon dioxide per unit mass but is present in much lower concentrations. Its total radiative forcing is less than that of carbon dioxide, so it is not the largest contributor to anthropogenic warming.

Option C:
Option C, chlorofluorocarbons, are powerful greenhouse gases and ozone-depleting substances, but due to regulation under the Montreal Protocol, their emissions have declined. Their overall contribution is less than that of carbon dioxide.

Option D:
Option D is correct because carbon dioxide is emitted in very large quantities from energy, transport and land-use change. Its long atmospheric lifetime and cumulative build-up make it the major contributor to human-induced climate change.

Statements A, B and D are correct and together summarise the relationship between carrying capacity, environmental limits and sustainable development. Carrying capacity describes the maximum sustainable load on an environment, and exceeding it can cause depletion and degradation. Sustainable development tries to align human activities with these ecological limits. Statement C is incorrect because technological innovations can increase or sometimes decrease effective carrying capacity by changing resource use efficiency and environmental impact. Hence, the correct combination is A, B and D only.

Option A:
Option A is incorrect because it lists only A and B, leaving out D. Although A and B accurately define carrying capacity and consequences of overshooting it, D is also correct in linking sustainability goals to staying within ecological limits. Excluding D makes the set incomplete.

Option B:
Option B is incorrect because it combines B, C and D and treats C as correct. C is wrong because technology can alter carrying capacity, for example through improved agricultural productivity or more efficient energy use. Including a false statement makes this combination unacceptable.

Option C:
Option C is incorrect because it asserts that all four statements A, B, C and D are correct. While A, B and D are correct, C contradicts the dynamic understanding of carrying capacity influenced by technological and social changes. The presence of an incorrect statement invalidates the entire set.

Option D:
Option D is correct because it identifies the three statements that align with ecological and sustainability concepts and excludes the one that is clearly false. It recognises both the definitional and policy dimensions of carrying capacity and reflects the essence of the development–environment relationship in the unit.

The tragedy of the commons refers to situations where no one owns a resource and each user has an incentive to take as much as possible. When everyone behaves this way, total extraction exceeds sustainable limits and the resource is degraded or destroyed. The problem lies in unregulated open access, not in sharing itself. Hence, the option describing overuse by self-interested individuals leading to degradation is correct.

Option A:
Option A is incorrect because nature alone cannot guarantee conservation when human extraction is unregulated. Without rules, open-access resources are vulnerable to overuse.

Option B:
Option B is correct as it captures the core mechanism: individual self-interest in open-access situations can produce collectively harmful outcomes. It summarises Hardin’s argument about grazing on common pastures.

Option C:
Option C is incorrect since communities with shared rules can often manage resources sustainably. Many studies show successful common property regimes that avoid tragedy through collective action.

Option D:
Option D is incorrect because private ownership does not always lead to depletion. Owners may have strong incentives to manage resources prudently over time.

The National Disaster Management Authority is the apex body for disaster management in India. Under the Disaster Management Act, the Prime Minister serves as its chairperson, signalling high-level political commitment to disaster risk reduction. This arrangement facilitates coordination among ministries and between the central and state governments. Therefore, identifying the Prime Minister as the head of NDMA is correct.

Option A:
Option A is correct because it matches the statutory design that places disaster management under the direct leadership of the head of government. This ensures that major disaster responses and policies receive attention at the highest executive level.

Option B:
Option B is incorrect since the Finance Minister, while crucial for allocating funds, does not chair the NDMA. Financial decisions support disaster programmes but do not confer leadership of the authority.

Option C:
Option C is incorrect; the Chief Justice of India leads the judiciary and does not head executive agencies. Courts may review disaster-related actions, but they are institutionally separate from NDMA.

Option D:
Option D is incorrect because the Chief Election Commissioner oversees electoral processes. Election management and disaster management are distinct domains with separate legal frameworks and authorities.

Carbon credits are units created when a project or activity demonstrably reduces or removes greenhouse gas emissions compared to a baseline. Each credit corresponds to a specific quantity, often one tonne of CO₂ equivalent, and can be traded and used for compliance in emissions trading schemes.

Option A:
Option A is incorrect because credits reward emission reductions, not fossil fuel production; fossil fuel subsidies undermine mitigation goals.

Option B:
Option B is correct as it emphasises both the tradable nature and the quantified emission reduction or removal that a credit represents.

Option C:
Option C is incorrect since a tax on renewable energy would discourage clean energy and is unrelated to the concept of credits.

Option D:
Option D is incorrect because credits exist within capped or regulated systems and do not give unlimited permission to pollute; entities must hold enough credits to match their emissions.

Statements A and B express the core idea of sustainable development, which is to balance economic growth with environmental protection and social equity while meeting present needs without compromising the ability of future generations. Statement C is incorrect because sustainable development does not reject technological innovation; instead, it promotes cleaner and more efficient technologies. Statement D is incorrect because sustainable development discourages over-exploitation of resources and promotes their prudent use. Therefore, the only correct combination of statements is A and B.

Option A:
Option A is correct because it includes statements A and B, both of which accurately define sustainable development as a balance among economic, environmental and social dimensions and emphasise intergenerational equity. Neither of these statements contains any exaggeration or contradiction with accepted definitions used in policy documents and UGC NET syllabus. Since statements C and D are false, excluding them makes this combination fully correct.

Option B:
Option B is incorrect because it adds statement C to the otherwise correct pair A and B. Statement C wrongly suggests that sustainable development rejects technological innovation, whereas in reality sustainable development encourages innovations such as renewable energy, cleaner production and eco-friendly technologies. Including an incorrect statement makes the whole combination wrong.

Option C:
Option C is incorrect because it combines B, C and D. Although statement B is correct, statements C and D are both incorrect. Statement C misrepresents the role of technology, and statement D promotes over-exploitation of resources, which is against the principle of sustainability. Due to the presence of these false statements, the combination cannot be correct.

Option D:
Option D is incorrect because it includes all four statements A, B, C and D. While A and B are true, C and D contradict the very idea of sustainable development by rejecting technological solutions and encouraging overuse of resources. A correct combination must exclude false statements, so selecting all four statements leads to an incorrect answer.

Mission documents state that India aims to develop at least 5 MMT per annum of green hydrogen production capacity by 2030. To supply this, about 125 GW of additional renewable energy capacity will be needed, creating a large clean-power ecosystem. This mission is expected to cut fossil fuel imports, abate around 50 MMT of CO₂ annually and generate substantial investments and employment. (hareda.gov.in)

Option A:
This option correctly states the numerical production target and its linkage to large-scale renewable capacity, matching official descriptions of the mission.

Option B:
This option understates both the scale of hydrogen production and the renewable energy requirement, and therefore does not match the approved mission.

Option C:
Producing hydrogen from coal does not qualify as green hydrogen and contradicts the decarbonisation objective; no such 50-MMT coal-based target has been announced.

Option D:
The mission explicitly sets quantitative goals; it is not restricted to small pilots with no numbers.

Climate smart agriculture (CSA) is explicitly defined as an approach that pursues three objectives: sustainably increasing agricultural productivity,adapting and building resilience to climate change and reducing or removing greenhouse gas emissions where possible. The stem restates these three aims,so climate smart agriculture is clearly the intended term. Therefore Option C is correct.

Option A:
Subsistence agriculture focuses on producing food mainly for household consumption with low external inputs. It is not inherently designed around climate resilience or mitigation objectives,so it does not match the description.

Option B:
Intensive agriculture emphasises high yields per unit area,often through heavy use of fertilisers,irrigation and pesticides. Without specific safeguards,it can worsen emissions and vulnerability,which is opposite to the climate smart goals.

Option C:
Climate smart agriculture encourages practices like improved crop varieties,water management,agroforestry and better livestock feeding. These techniques address productivity,resilience and emissions together,just as the question describes.

Option D:
Slash and burn agriculture involves clearing and burning vegetation to create temporary fields. It can lead to deforestation and higher emissions and is generally not considered climate smart,so this option is inappropriate.
