Agriculture India has been described as one of 12 mega-diversity countries possessing a rich means of all living organisms when biodiversity is viewed as a whole.
A Mega Diversity Nation Article shared by India, the largest democratic republic of the world, has the seventh largest area It has diverse geographical features and varied climates. It has 14 major basins through which drain numerous rivers. While rivers such as the Ganga originating from the mountains are snow-fed, those emanating from central and southern India are rain-fed, with little perennial water.
The annual rainfall varies from less than 37 cm in Rajasthan to m in Cherapunji, Meghalaya.
Three different seasons — winter, summer and monsoons are experienced. However, the seasonal severity varies considerably. The diversity in physical and climatic setting produces a markedly diverse fauna and flora.
The vegetation ranges from xerophytic in Rajasthan, evergreen in the North-East and the Ghat areas, mangroves of coastal areas, conifers of the hills and the dry deciduous forests of central India to alpine pastures in the high reaches of the Himalaya.
It also has two global terrestrial biodiversity hot spots — the North-eastern States and the Western Ghats. Naturally, such a diverse flora provides for a very diverse fauna. The forests of the country from tropical rain forests in the south and the northeast to the dry alpine forests in the northwest Himalaya have been classified into 16 types and subtypes on the basis of climatic and edaphic conditions.
Some of the principal commercial species are highly valued and are becoming increasingly costly, e. Together with a host of non-timber forest product such as gums, resins, fruits, nuts, oil, dyes and medicinal plants, the value of forest products, both for subsistence and industrial use, is increasing exponentially.
Forests are also the most important source for fibre for paper and pulp industries, with bamboo occupying the key position. These ecosystems have given India 10 biodiversity rich zoogeographic zones.
Biodiversity is the variability among living organisms and the ecological complexes of which they are part including diversity within and between species and ecosystem. Biodiversity has direct consumptive value in food agriculture, medicine and in industry.
The CBD is an international legal instruments for promoting conservation and sustainable use of biological diversity taking into account the need to share cost and benefit between developed and developing countries and ways and means to support innovation by local people.
It was resolved to evolve an international regime on access to genetic resources and benefit sharing with the aim of adoption of an instrument with the provisions of CBD.
India has prepared the Third National report to the convention of Bio-diversity. A scheme on biodiversity conservation was initiated earlier to ensure coordination among various agencies dealing with the issues related to conservation of bio-diversity and to review, monitor and evolve adequate policy instruments for the same.
Important steps taken are— i A comprehensive project National Bio-diversity Strategy and Action Plan NBSAP was launched for preparation of planning document relating to ecological security and livelihood of people depending on national resources.Two areas in India have been identified as megadiversity hot spot areas, which are western ghat forests and eastern Himalayan forests, but India as a whole country as megadiversity nation.
Miller Meier says, ‘India is remarkable in both species richness and endemism although it ranks 10 th position. Why India said to be megadiversity nation.

Originally Answered: How is India a mega-biodiversity nation?
With per cent of the world’s land, India contributes 8 per cent to the world diversity. It has therefore, been designated as one of the 12 megadiversity regions of the world.
These include especially high species diversity of ferns ( species) and orchids ( species). India has 50, known species of insects, including 13, butterflies and moths.
It is estimated that the number of unknown species could be several times higher.
