Rice being the staple food crop holds the key for food security of India. It is grown in about 44 m.ha with a production of about 99 m.t. At the current rate of population growth and per capita consumption, rice requirement by 2025 is estimated to be around 130 m.t. Keeping this in view, the Government of India has launched the National food Security Mission to achieve the production of additional 10 million tons of rice by the end of the XI plan period Production of additional 20-30 m.t. of rice by 2025 has to come in the backdrop of declining resources such as land, water, labour and the costly inputs. Area under rice is expected to be reduced to about 40 m.ha in the next 15-20 years and most of this reduction is attributed to water shortages and rapid urbanization. Recent estimates indicate that there would be acute water shortages in the coming decades. More than 80 per cent of fresh water is consumed for agriculture and 50% of it goes for rice cultivation. Rice consumes about 4000 - 5000 liters of water to produce 1 kg of rice. Therefore, rice cultivation could face a threat due to water shortages and hence there is an urgent need to develop and adopt water saving methods in rice cultivation so that production and productivity levels are elevated despite the looming water crisis...RiceFood SecurityIndian Agriculture2011-04-08Directorate of Rice Research (DRR)Monograph
