Which of the following categories of protected areas, as defined by the IUCN, is primarily aimed at protecting natural ecosystems and species, allowing for scientific study and environmental monitoring?
A Category Ia: Strict Nature Reserve
B Category V: Protected Landscape/Seascape
C Category VI: Protected Area with Sustainable Use of Natural Resources
D Category III: Natural Monument
Answer: A
Strict Nature Reserves (Category Ia) are protected areas set aside for the purpose of scientific research and environmental monitoring, with minimal human interference.

The 'Panchamrit' strategy, announced by India at COP26, outlines five key targets for climate action. Which of the following is NOT one of these targets?
A Achieve Net-Zero emissions by 2070.
B Increase non-fossil fuel energy capacity to 500 GW by 2030.
C Reduce total projected carbon emissions by one billion tonnes from now to 2030.
D Reduce the carbon intensity of the economy to below 45 percent by 2030.
Answer: D
'पंचामृत' रणनीति में 2070 तक शुद्ध-शून्य प्राप्त करना, 2030 तक गैर-जीवाश्म ईंधन ऊर्जा क्षमता को 500 GW तक बढ़ाना, अब से 2030 तक कुल अनुमानित कार्बन उत्सर्जन को एक अरब टन तक कम करना, और 2030 तक अर्थव्यवस्था की कार्बन तीव्रता को 45 प्रतिशत से नीचे लाना शामिल है। अंतिम बिंदु गलत है क्योंकि लक्ष्य 2030 तक कार्बन तीव्रता को 45 प्रतिशत से नीचे लाना है, न कि 45 प्रतिशत से नीचे।

India's Nationally Determined Contributions (NDCs) under the Paris Agreement include a target to reduce the emissions intensity of its GDP by 33-35% by which year?
A 2025
B 2030
C 2035
D 2040
Answer: B
One of India's key NDCs is to reduce the emissions intensity of its GDP by 33-35% from 2005 levels by the year 2030.

Which of the following national missions under the National Action Plan on Climate Change (NAPCC) primarily focuses on enhancing the adaptive capacity of various sectors to climate change?
A National Solar Mission
B National Mission for Enhanced Energy Efficiency
C National Mission on Sustainable Agriculture
D National Water Mission
Answer: C
The National Mission on Sustainable Agriculture (NMSA) aims to address the challenges posed by climate change to agriculture, focusing on enhancing adaptive capacity, productivity, and resilience.

Research on rising sea levels in the Sundarbans often involves studying the impact on:
A The migratory patterns of birds.
B The salinity tolerance of mangrove species.
C The frequency and intensity of tidal flooding.
D All of the above.
Answer: D
Research in the Sundarbans concerning sea-level rise is multifaceted. It examines how rising waters affect bird migration, the physiological responses of mangroves to increased salinity, and the direct impact of more frequent and severe tidal flooding on the landscape and its inhabitants.
86.
Which of the following is a major consequence of sea-level rise for the Sundarbans ecosystem?
A Expansion of mangrove forests due to increased sediment deposition.
B Loss of habitat for the Royal Bengal Tiger and other wildlife.
C Improved water quality for aquatic life.
D Reduced salinity in the soil, benefiting agriculture.
Answer: B
As sea levels rise and erosion increases, low-lying areas of the Sundarbans, including critical tiger habitats, are submerged or become more saline, leading to habitat loss and displacement for wildlife.
87.
Rising sea levels pose a significant threat to the Sundarbans primarily due to:
A Increased frequency of cyclones and storm surges.
B Salinization of freshwater sources.
C Erosion of mangrove forests and coastal land.
D All of the above.
Answer: D
Rising sea levels exacerbate all these issues in the Sundarbans. Higher sea levels lead to more intense storm surges, increased coastal erosion, and saltwater intrusion into freshwater systems, threatening the unique ecosystem and its inhabitants.
88.
The success of a wildlife green corridor often depends on the cooperation between:
A Only forest departments of different states.
B Central government and international organizations.
C Forest departments, local communities, and private landowners.
D Wildlife researchers and veterinary doctors.
Answer: C
Effective green corridors require integrated land management. This involves collaboration among government agencies (like forest departments), local communities whose land may be part of the corridor, and private landowners whose cooperation is essential for seamless connectivity.
89.
Which of the following is a key objective of establishing wildlife green corridors?
A To increase tourism revenue in protected areas.
B To ensure genetic diversity and population viability of species.
C To develop infrastructure for wildlife research.
D To create buffer zones around national parks.
Answer: B
By connecting fragmented populations, green corridors allow for gene flow, which is crucial for maintaining genetic diversity and preventing inbreeding depression, thus ensuring the long-term viability of species.
90.
The Green Corridor Initiative, recently in news, is primarily aimed at:
A Connecting fragmented wildlife habitats to facilitate animal movement and reduce human-wildlife conflict.
B Creating artificial green spaces in urban areas for biodiversity conservation.
C Promoting afforestation drives along national highways.
D Establishing wildlife rescue and rehabilitation centers.
Answer: A
The Green Corridor Initiative focuses on creating safe passage for wildlife by connecting isolated habitats, thereby reducing mortality due to road accidents and facilitating gene flow.
