Title : Traditional Rice landraces cultivation and its importance towards Human Food and Nutritional Security


                       At present the World is facing agrarian as well as nutritional challenges. Agricultural lands with irrigation facilities have been exploited to maximum.Water foot print is discussed in terms of its water use and its’ efficiency, defined as the amount of carbon assimilated as biomass or the grain produced per unit of water used (consumed). The whole concept and the process depends upon the carbon and water dynamics with bio-chemical and metabolic process during the plant growth. Rice cultivation is of immense importance to food security of Asia, where more than 90 per cent of the global rice is produced and consumed with more than two billion people getting sixty to seventy per cent of their energy requirement from rice and its derived products. This crop alone provides 32-59 per cent of the dietary energy and 25-44 per cent of the dietary protein among consumers at the global level. Traditional rice land races with medicinal values are confined to certain pockets cultivated in states of Karnataka, Madhya Pradesh, Kerala, Tamil Nadu, Uttar Pradesh, Himachal Pradesh and Western Ghats in India

                           The traditional rice types, mostly being the local land races is exploited by the rural folks to treat skin disease, blood pressure, fever, rheumatism, lactation and used also as a health tonic. Some of the rice landrace types are used in sidda and ayurvedic for exploiting the curative value and is used in many medicinal preparations.The cultivation of traditional rice landrace are confined to certain pockets (localised area) depending on its suitability to climate and soil type, under varied level and quantity of water requirement, having also high degree of resistance to pests and diseases, known to have specific nutritional and therapeutic properties. Cultivation of rice landraces have survived in many disasters in comparison to HYV and popular rice varieties. The traditional varieties are exploited in sidda medicine, due to medicinal properties and health benefits. Hence there is a need for us to reassess and revive the values attributed by traditional rice towards Human Food and Nutritional Security.
