Introduction to Biodiversity:
India is one of the world’s most biologically and culturally diverse countries. It is also one of the poorest in terms of per capita income.
The existence of mass poverty on an enormous scale lies upon two important facts: first that the country exports natural products that command high prices in overseas markets, such as basmati rice and Darjeeling tea, as well as products like medicinal and aromatic plants that are major inputs in rapidly expanding industries; and second that India has achieved significant capabilities in industrial chemistry and the life sciences (Table 7.2).
India is one of the world’s ‘mega diversity’ countries. It is ranked ninth in the world in terms of higher plant species richness. At the ecosystem level, India is also well-endowed, with ten distinct biogeographic zones.
It also contains two of the world’s 25 biodiversity hotspots, because of their extraordinarily high levels of species-richness and endemicity, and threatened status.
India is considered to be the centre of origin for the following crop species pigeon pea, egg plant cucumber, possibly cotton and sesame. But for millennia, numerous other crop species have been introduced to India and adapted to localised conditions.
As a consequence of both the diversity of these conditions and of the various ethnic populations living in India, the country has become an important centre of diversity of a great many domesticated species, including various cereals, millets, legumes, vegetables, temperate and tropical fruits, fibre crops, medicinal and aromatic plants.
