Paddy-field conservation and administrative dilutionConservation objectives can be weakened through administrative rules and regularisation practices. The issue concerns implementation design as well as enforcement.
21 Oct 2026Environment & EcologyPaddy-land governance — regulatory dilution and ecological outcomes
A strong conservation statute may fail when administrative incentives favour land conversion. Examine with reference to paddy-field ecosystems and suggest institutional remedies. (150 words, 10 marks)17 Oct 2026Environment & EcologyLegacy industrial chromium pollution and remediation accountability
Groundwater contamination by persistent industrial pollutants exposes weaknesses in both environmental regulation and public-health protection. Discuss, using chromium contamination as an illustration, and propose an accountable framework for remediation. (250 words, 15 marks)22 Oct 2026Environment & EcologyCORSIA – scope, offsetting and eligible aviation fuels
Consider the following statements about the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA): 1. It operates under the International Civil Aviation Organization. 2. It is an economy-wide emissions-trading system covering domestic transport and electricity generation. 3. Recognised life-cycle emissions reductions from eligible aviation fuels can reduce an aircraft operator's offsetting requirements. Which of the statements given above are correct? Select the correct answer using the code given below:22 Oct 2026Environment & EcologyCetaceans – baleen feeding, resident populations and observation bias
Consider the following statements: 1. The blue whale feeds using baleen plates rather than functional teeth. 2. The Arabian Sea humpback whale population is known for remaining within the region rather than undertaking the long migrations typical of many other humpback populations. 3. A decline in recorded whale strandings necessarily demonstrates a decline in whale occurrence along that coast. How many of the above statements are correct?21 Oct 2026Environment & EcologyPaddy-field ecosystem services — storage and flood regulation
Consider the following statements: Statement-I: Conversion of low-lying paddy fields into built-up land can increase local flood risk. Statement-II: Paddy-field landscapes can temporarily store water and regulate local hydrological processes. Which one of the following is correct in respect of the above statements?17 Oct 2026Environment & EcologyChromium speciation and groundwater treatment
With reference to chromium contamination of groundwater, consider the following statements: 1. Trivalent and hexavalent chromium have identical chemical behaviour and toxicity. 2. Reduction of hexavalent chromium to trivalent chromium, followed by suitable precipitation and separation, can be used in chromium-removal treatment. 3. Ordinary boiling necessarily removes dissolved chromium from contaminated water. Which of the statements given above is/are correct?Showing published editions from the last 90 days.
