Read the passage and answer the questions given below: 

Conservation of plant biodiversity for sustainable growth and development has been the major concern of all the countries after the Convention of Biological Diversity held in 1992, which provided sovereign rights of the states over their national resources. Being the major staple crop for more than half of the world population, conservation and protection of vast generic of rice has got the top priority in India and also other rice growing countries. Majority of these generic resources were conserved by the local communities throughout the length and breadth of the country and the Government of India rightly recognised them as custodians of these generic resources. The issue of protecting of plant varieties came into focus after the birth of World Trade Organisation (WTO) in 1995. Accordingly, the Protection of Plant Varieties and Farmer’s Act was enacted in 2001 by the Government of India, while recognising the services rendered by Indian farmers and exhaustive privileges and provisions were included in the Act as Farmer’s Rights which no other country in the world recognised. Rice with its rich generic repositories and wide adaptability is the only crop that can offer solutions to the daunting goal of curbing hunger. Any threat to the biodiversity in rice is a direct threat to the survival of mankind.
