CGIAR Climate's insight:
The CGAIR Research Program on Climate Change, Agriculture and Food Security this month released a report on alternate wetting and drying in irrigated rice. Key messages Alternate wetting and drying (AWD) is a rice management practice that reduces water use by up to 30% and can save farmers money on irrigation and pumping costs. AWD reduces methane emissions by 48% without reducing yield. Efficient nitrogen use and application of organic inputs to dry soil can further reduce emissions. Incentives for adoption of AWD are higher when farmers pay for pump irrigation. - See more at: http://oryza.com/news/research-development/cgair-shares-latest-findings-alternate-wetting-and-drying-rice-management#sthash.fRiYA8L1.dpuf
