Rice is life
Rice
is life for millions of people in the world, particularly in
developing countries. It is the main cereal for majority population in
India. The demand for rice is growing with ever-increasing population.
Rice is water intensive crop. More than 70 percent of the
country’s ground and surface water is being used for
agriculture, and out of this, 70 percent is allocated to rice
cultivation. Each kg of rice produced with irrigation requires
3000-5000 litres of water.
Water and food security
Increasingly water is becoming single most constraint to produce more rice to meet increasing demand. In spite of providing assured irrigation, use of pest-resistant high-yielding varieties, and high inputs of fertilisers and pesticides, rice yields in India are plateauing. With inevitable growth of demand for human and industrial needs, water available for agriculture will become scarcer in future. Hence, India needs to invest on improving its water productivity, and any capacity to produce more rice with less water will be an important contribution to sustainable water and food security.
