The CGIAR Research Program on Aquatic Agricultural Systems (AAS) takes an innovative approach to improving the lives of poor and vulnerable rural households. It aims to directly benefit some 6 million people (in Asia's mega deltas, the island systems of the Pacific and Southeast Asia, and Africa's inland waters), and through scaling with partners to reach 15 million more. By sharing its learning, the program aims to extend the benefits of its approaches to many more people living in other complex systems. By the end of 2013, the AAS program had completed two full years, with the first phases of implementation concluded in five hubs: southern polder zone (Bangladesh), Tonle Sap (Cambodia), Visayas-Mindanao (Philippines), Malaita (Solomon Islands) and Barotse Floodplain (Zambia). This report presents key achievements and outcomes for the AAS program up to 2013.
