Chhattisgarh state located in central India covers total area of about 13.5 million hectares. The region has a great variety and diversity of weather conditions. Three major agro-climatic zones has been demarcated in the state viz.,  Chhattisgarh plains zone,  Bastar plateau ACZ and  Northern hill region. Here an analysis of rainfall for 16 districts has been made and interpretation drawn regarding pre-dominant crop rice cultivation. Further stress has been made to conserve surplus monsoonal rainfall in On Farm Reservoirs (OFR’s) as rainfall is occurring in intense storms and utilize this rainwater for sustainable crop production and also for enhancing cropping intensity. The high potential of OFR’s and other harvesting structures in alleviating drought,  increasing productivity and stability of rainfed  ricelands has been tested in this region for meeting this challenge of rainfed rice production.
