Water is critical to life and to farming. Two key issues affecting water are: access to water, and managing water. Access can be improved through household or community storage of water. Access to water is also improved through water efficiency, i.e. using the water wisely to make it last longer; and through recycling water. 

These guidelines provide techniques on water use efficiency and recycling, water harvesting and storage, infiltration, small dams, and small-scale irrigation schemes. By improving access to water, water can also be managed more sustainably, which is beneficial both to the community and to the catchment at large.
