As per the recent information available, it has been indicated that over the long term, pressures on food and nutrition security in Asia and the Pacific are likely to intensify due to changing demographic and consumption patterns. According to the reports, the Asia and the Pacific is one of the world’s most dynamic regions, where rapid transformations make it necessary to rethink strategies for food and nutrition security. In case to meet future food demand, crop yield must be increased at the annual growth rate of 2.4%, which is required to double food production by 2050. Closing the existing crop yield gaps and the genetic improvement of crop yields is of strategic significance for ensuring food and nutrition security at global, country, and household levels.
Further, it has been revealed that rice cultivation systems in Asia need transformational changes in crop establishment methods due to dwindling water resources, rising labor costs, and inadequate labor during the peak farming periods. To solve these problems, the proven water-saving technologies for both irrigated and rainfed rice cultivations such as direct seeded rice and alternate wetting and drying are available. Their wide dissemination combined with suitable improved rice varieties that responds best to local agroecology which has promising prospects in closing the existing wide yield gaps and it also help to boost food security in Asia.
Further, in this regards, for scaling the adoption of water-saving technologies and improved rice varieties, the modernization of agricultural practices including precise land leveling, mechanized seeding, precise water management, efficient weed control, efficient nutrient management, and mechanized harvesting and threshing are needs to be introduced together to help farmers to realize a positive returns from the shift in rice cultivation systems. In this matter, the Governments can play an important role in scaling the adoption of advance technologies by supporting research and development, improving institutional outreach of extension services, investing in critical utilities and infrastructure that support water-saving technologies, and introducing regulatory reform to institute incentives for farmers.
