Water Harvesting examples

Example of water harvesting using Stone Lines

Example of water harvesting using Fanya Juu Terraces

Stone lines or ("bunds") slow down runoff and increase water infiltration to improve production in semi-arid areas. At the same time, sediment is captured behind these semi-permeable barriers. Stone lines were originally a traditional technique in the Sahel, but have been improved by careful construction, and through aligning them onto the contours of the land.
A perennial grass (Andropogon guyanus) is sometimes planted to supplement the lines where stone is scarce. Stone lines are suited to low slopes, high runoff and hand labour. This technique is readily adopted by resource-poor farmers and can lead to a harvest even in years with low and erratic rainfall. Wide and deep planting pits (called 'zai' in Burkina Faso; 'tassa' in Niger) are often used in combination, acting as microcatchments within the field.

Contour earth bunds are constructed by throwing soil upwards from trenches immediately below them. This design leads to the gradual formation of terraces with a level or slightly forward sloping bed.

This is a very versatile technology - ideally suited to smallholder farms, especially in sub-humid areas where the land is sloping and erosion a threat. Fodder grasses may be planted on the bunds and fed to livestock. In the dry areas, water harvesting from roads into the trenches allows production of bananas and fruits. This is a proven and effective adaptation technology in the highlands of East Africa and beyond.

Zero impact area's

  Diversion Weirs

Zero-impact area's targets recovery of soil coverage in the Tigray area. Fences disable livestock and humans to enter protected zones, so that vegetative species find time to regenerate. Hand-in-hand with other soil and water conservation measures, this method is baring fruit, as soil coverage and species diversity increased. The video highlights the arrival of new flowering plants, which stood at the basis of the revival of the honey industry. Honey is now the 4th biggest export of Ethiopia.

In Kifle Awlaelo, Tigray province, Northern Ethiopia 26 families are digging and shaping a new well to serve their community. Following the soil and water conservation measures taken in Tigray over the past 20 years, groundwater tables have risen making it easier for communities to access groundwater resources.
