Presentation on the Kenya Arid Lands project which is working to improve access to water, sanitation and hygiene (WASH) and build resilience to climate change. See also the calculation example for assessing water needs.

Many farms in tropical countries suffer from droughts in the dry season and sometimes even in the rainy season. In order to significantly increase the capacity to store water, the grassroots Farmer Wisdom movement in Northeast Thailand innovated pond construction on homesteads. This Working Paper first documents how pond water is mainly used to irrigate crops and fruit trees, and is also used for livestock or fish, and for domestic uses, even if ample piped water is available. Households were also found to harvest rainwater from roofs; take water from canals and streams; lift water manually from shallow wells and with electric pumps from deep wells; channel run-off from roads to paddy fields; use precipitation as green water on fields; and buy bottled water. Most households combine at least six of these nine water sources. The second part describes scenarios and some outcomes of a new simulation model, BoNam. This model provides guidelines for the optimal size and site of such ponds according to biophysical factors (weather, soil and crops), socioeconomic factors (prices, availability of labor and off-farm income) and household aspirations
Isabel Dominguez presented work as a result of her MSc thesis, and a technical exchange between Cinara and WEDC, dealing with a water balance for MUS in Colombia, amongst other using both green and blue water balances.
This thesis report studies the water balance in a MUS system in Colombia. It shows amongst others the importance of identifying different strata of users in the system, as these have different consumption patterns. Using the water balance concept, it shows the relative importance of water supply from the system and greenwater for different domestic and productive uses.
This presentation looks into how urban water supplies in Nigeria are used for productive purposes and the benefits derived from this.
This paper provides a synthesis of research on multi-purpose water systems carried out under the first phase of the Challenge Program on Water and Food, and elsewhere. In addition, it provides elements to guide research in its second phase.
