Environment and Ecology has been an important segment for UPSC Civil services Preliminary examination. Since last few years has seen inclusion of questions from Environment Section. The reason might be due to rising awareness regarding environment and conservation efforts globally. One more reason is cited behind this trend is Indian Forest Service Exam that is conducted along with UPSC Prelims Exam. Out of the total questions asked from environment a substantial number of questions are asked from Biodiversity hotspots, biosphere reserves and tiger reserves .  Students have to prepare this segment really well to tackle any unpredictable questions of the UPSC Prelims Examination. In todays article we will discuss a strategy to prepare such questions for UPSC Prelims Exam point of view.

Before discussing the strategy lets have a look at these terms and understand why these areas are important from exam point of view. Biodiversity is referred to as the variation of plant and animal species in a particular habitat. Biodiversity has an evenness and richness of species of flora and fauna . Biodiversity hotspots are those regions which has high richness of species and endemism . This term was coined by Norman Myres.

On the other hand Biosphere reserves are those protected areas where conservation of plants and animals is carried out. The biosphere reserves  also restores the traditional life of the tribals living in that vicinity.  Biosphere reserves are aimed at conservation of the biodiversity in that particular area. The Biosphere Reserves are identified by the Man and Biosphere Reserve Program to promote sustainable development. This program was initiated by UNESCO in 1971. The Man and Biosphere Reserve Program recognize such areas which have following characteristics

  • They should be  world’s most typical terrestrial and coastal ecosystems.
  • They should exhibit approaches to live and works in harmony with nature.
  • They should  demonstrate the achievement of a sustainable balance between conserving natural ecosystems and biodiversity.

There are three zones in biosphere reserves :

  • Core
  • Buffer
  • Manipulation

Tiger Reserve is  a 'Core' or 'Critical Tiger Habitat', which is to be managed as an inviolate area, and a 'Buffer' or Peripheral area immediately abutting a Core area, which may be accorded a lesser degree of habitat protection. This is the typical zonation of a Tiger Reserve.
