Technological Package for Agro-pastoralists
1. Farm pond for runoff storage
The farm pond is an underground runoff storage reservoir – a truncated rectangular pyramid shaped – lined with a 0.8mm thick ultra-violet resistant plastic sheet (to control seepage losses), and roofed either with iron sheet or shade net (to reduce evaporation, contamination, and risk of drowning). The farm pond harvests surface runoff and direct precipitation (either from iron sheet roof or through the 80% shade net roof). For a 50m3, the top and bottom dimensions are 8m by 6m, and 4m by 2m respectively, while the depth is 2m – with 1:1 side slope. Different dimensions for the farm pond can be adopted, for example 72 or 90m3 storage capacity, are being promoted for primary schools – vegetable production, establishment of tree seedling nurseries, and supplementary irrigation of tree and fruit seedlings.
