Rainwater harvesting systemto ensure sustainability of smallholder farmers
Low availability of water for irrigation and consumption, particularly in the four months of low rainfall.
Climate challenge
Practice description
Development of a water-harvesting structure for the storage and use of rainwater in irrigation and domestic uses (not human consumption), which allow to collect, distribute and store the water to be used especially during the dry season. It is non-polluting, and encourages the efficient use of water.
Technical aspects
The practice contributes to adaptation and food security given that together with the harvested water, this prac-tice ensures the supply of water for domestic requirements and irrigation of the home garden. The practice also contributes to mitigation given that water is used more efficiently.
Implementation and results
Contribution to CSA pillars
Due to the shortage or unavailability of water, especially in times of low rainfall, how is it possible to maintain the productivity of the farm, storing rainwater?
Research question
Estimation of monthly water requirementsfor the farm and the feasibility of developing the structure.
The farm 'El Nacedero' requires 16m3 / monthfor agricultural activities,of which 70% is for irrigationand 30% for domestic use.
11.2m3

With rainwater harvesting,it is possible to store all the rainfall to beused during the dry season, which rangesfrom 8 to 5m3 during the four months.
The water collected duringthe dry season ensures waterfor the home garden andhousehold chores.17m3
