Developing and Disseminating Water-Saving Rice Technologies in Asia

Publication | June 2016

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.

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.

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.

Key Points

  • 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.
  • Proven water-saving technologies for both irrigated and rainfed rice cultivations such as direct seeded rice and alternate wetting and drying are available, and their wide dissemination—combined with suitable improved rice varieties that best respond to local agroecology—has promising prospects in closing existing wide yield gaps and helping boost food security in Asia.
  • 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—needs to be introduced together to help farmers realize positive returns from the shift in rice cultivation systems.
  • 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.
