Environmental analysis provides insights into planning and managing, rice farming according to the prevailing conditions. This helps in developing situation-specific technologies and in selecting areas suitable for the application of promising technologies, particularly in rainfed conditions. Studies carried out in eastern India characterized and classified the rainfed rice area in different rice ecosystems and subecosystems and elucidated the main problems and opportunities for enhanced productivity in them. A detailed analysis of the principal rice subecosystems provided the periods and quantities of water surplus and deficit and moisture use and recharge patterns along with other climatic variables during the rice-cropping season. This information was used for selecting the technological interventions that were considered suitable for managing rice farming in such areas. The interventions were compared with the farmers' normal practices by monitoring crop performance at selected locations in two rice ecosystems.
