Agriculture in India needs to become more sustainable even as small and marginal farmers struggle to build resilience against many threats. First, they remain pricetakers and economically vulnerable, beholden to traders who set prices, and with limited opportunities to sell at a time of their choice (due to poor storage). Further, decades of intensive agriculture have added to water stress and declining soil health. Farmers rely on groundwater for more than 60% of irrigation needs. Chemical fertilizers, once a boon to boost soil nutrients, have been applied so intensively (particularly urea) that the longterm health of soils is now of deep concern.

To match the demand for low and semiskilled workers, agencies like the World Trade Organization (WTO) and the World Bank promoted businessfriendly migration management approaches, while snubbing worker and migrant rights.

Individuals, groups and leaders who promote human development operate under strong institutional, structural and political constraints that affect policy options. But experience suggests broad principles for shaping an appropriate agenda for human development. One important finding from several decades of human development experience is that focusing exclusively on economic growth is problematic. While we have good knowledge about how to advance health and education, the causes of growth are much less certain and growth is often elusive. Further, an unbalanced emphasis on growth is often associated with negative environmental consequences and adverse distributional effects. The experience of China, with its impressive growth record, reflects these broader concerns and underlines the importance of balanced approaches that emphasize investments in the non¬income aspects of human development.
Q. With reference to the above passage, consider the following statements:
In developing countries, a strong institutional framework is the only requirement for human development and policy options
Human development and economic growth are not always positively interrelated.
Focusing only on human development should be the goal of economic growth
