|Not all AWM solutions are appropriate in all locations due to physical and socio-economic conditions. The country level mapping tried to identify where AWM in general could contribute most to improving livelihoods and increasing the irrigated area. For each project country certain promising AWM solutions were also mapped to see where they would achieve greatest impact.
The process involved compiling national data, such as physical availability of water (rainfall, surface water or shallow groundwater) and the presence of smallholder farmers, based on population density and rural poverty rates. A participatory process was used to identify "livelihoods zones" – the criteria to determine livelihood zones are the main livelihood activity (for example rice farming, vegetable farming, tea growing or livestock rearing), the wider socio-economic conditions such as access to markets, and the physical conditions (for example highlands give rise to different livelihoods than lowlands and coastal areas).
The consultations led to a better understanding about the farmers who may use the AWM options, their need for solutions, their dependence on water resources, their average land holdings and their farming methods. All of this information has been combined into maps that show where AWM options are most suitable.
