Directions : In the following questions a statement of assertion (A) ...
Assertion (A) : Biosphere reserves are also included under the ex-situ conservation strategies.
Reason (R) : Cropping and grazing are allowed in the transition zone of biosphere reserve.
The correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
Explanation:
1. Biosphere reserves and ex-situ conservation strategies:
- Assertion (A) states that biosphere reserves are included under the ex-situ conservation strategies.
- Ex-situ conservation refers to the conservation of components of biological diversity outside their natural habitats.
- Biosphere reserves, on the other hand, are designated areas that aim to conserve the natural and cultural heritage of an area while promoting sustainable development.
- While biosphere reserves may include certain ex-situ conservation activities, such as seed banks or captive breeding programs, they are primarily focused on in-situ conservation, which means conserving species and habitats in their natural environments.
2. Cropping and grazing in the transition zone:
- Reason (R) states that cropping and grazing are allowed in the transition zone of a biosphere reserve.
- A biosphere reserve typically consists of three zones - the core zone, buffer zone, and transition zone.
- The core zone is the most strictly protected area where human activities are limited, while the buffer zone allows for some sustainable human activities.
- The transition zone is the outermost zone where agriculture, grazing, and other human activities are allowed.
- The purpose of the transition zone is to provide a buffer between the protected core zone and the surrounding areas, allowing for sustainable development and the coexistence of humans and nature.
3. Explanation of the correct answer:
- The correct answer is option 'D' because assertion (A) is false.
- Biosphere reserves are primarily focused on in-situ conservation rather than ex-situ conservation.
- However, reason (R) is true as cropping and grazing are indeed allowed in the transition zone of a biosphere reserve.
- The transition zone acts as a buffer between the strictly protected core zone and the surrounding areas, allowing for sustainable human activities while still maintaining conservation objectives.
In conclusion, while biosphere reserves may include some ex-situ conservation activities, they are primarily focused on in-situ conservation. Cropping and grazing are allowed in the transition zone of a biosphere reserve to promote sustainable development and the coexistence of humans and nature. Therefore, option 'D' is the correct answer.
