- Established a risk map on the effect of sea-level rise and climate change on salt intrusion in the Mekong Delta up to the years 2030 and 2050.
- Analyzed land suitability for potential land-use systems under different sea-level rise and infrastructure development scenarios, and the socioeconomic characteristics of each system in various agroecological zones.
- Developed improved rice varieties using conventional and complex crosses to investigate underlying genetics and the value of parental lines in breeding for stress tolerance.
- Conducted more than 49 participatory varietal selection trials using 41 rice varieties and distributed more than 27,600 kilograms of best-bet variety seeds to farmers from 2011 to mid-2013.
- Identified the combination of alternate-wetting-and-drying technology, reduced phosphorus use, and transplanting as a climate change-adaptive strategy for rice production in the Delta.
- Recommended a short-duration high-yielding rice variety that can replace the local variety Mot Bui Do in the shrimp-rice system in Bac Lieu Province.
- Improved farmers’ income through integration of non-rice crops into rice-based systems (although poor community water management remains a barrier to upland crop production).
- Identified determinants and solutions for further improvement of livelihoods of rice farmers in the Delta.
- Developed initial data on emissions in the Delta as a function of crop management.
The project began work in March 2011 and will conclude in February 2014. IRRI climate expert Reiner Wassmann is the project leader of CLUES. Other IRRI scientists involved are To Phuc Tuong, Russell Reinke, Abdelbagi Ismail, Thelma Paris, Romeo Labios, and Ngo Dang Phong.
