Suitability for Water Harvesting : Micro - Catchment system Semi-circular bunds, tree crops

The systems evaluated include 13 micro-catchment systems, based on combinations of 6 techniques and 3 crop groups, and one generalized macro-catchment system. The environmental criteria for suitability were based on expert guidelines for selecting water-harvesting techniques in the drier environments. They included precipitation, slope, soil depth, texture, and salinity, as well as land use/land cover and geological substratum. The dataset included interpolated surfaces of mean annual precipitation, a high-resolution digital elevation model, a soil map of Syria, a land use/land cover map of Syria, and a geological map of Syria. Semi-circular and trapezoidal bunds are usually e...

Develop a fast-track approach for identifying hot-spots of suitability for various water harvesting techniques based on multi-criteria analysis in GIS environment

The systems evaluated include 13 micro-catchment systems, based on combinations of 6 techniques and 3 crop groups, and one generalized macro-catchment system. The environmental criteria for suitability were based on expert guidelines for selecting water-harvesting techniques in the drier environments. They included precipitation, slope, soil depth, texture, and salinity, as well as land use/land cover and geological substratum. The dataset included interpolated surfaces of mean annual precipitation, a high-resolution digital elevation model, a soil map of Syria, a land use/land cover map of Syria, and a geological map of Syria. Semi-circular and trapezoidal bunds are usually earthen bunds in the shape of a semi-circle, a crescent, or a trapezoid facing directly upslope. They are created at a spacing that allows sufficient catchment to provide the required runoff water, which accumulates in front of the bund, where plants are grown. Usually they are placed in staggered rows. The diameter or the distance between the two ends of each bund varies between 1 and 8 m and the bunds are 30-50 cm high. Bunds are used mainly for the rehabilitation of rangeland or for fodder production, but may also be used for growing trees, shrubs and in some cases field crops and vegetables.

Pitting is a very old technique used mainly in Western and Eastern Africa, but adopted in some WANA areas. It is used for rehabilitating degraded agricultural lands. The pits are 0.3-2 m in diameter. The most famous pitting system is the zay system used in Burkina Faso. This consists of digging holes with a depth of 5-15 cm. Pits are applied in combination with bunds to conserve runoff, which is slowed down by the bunds. This system allows much degraded agricultural land to be put back into use. Pitting systems are used mainly for the cultivation of annual crops, such as cereals. If the pits are dug on flat instead of sloping ground, they may be regarded more as an in situ moisture-conservation technique than as water harvesting one.

Sometimes called negarim, small runoff basins consist of small diamond- or rectangular-shaped structures surrounded by low earthen bunds. They are oriented to have the maximum land slope parallel to the long diagonal of the diamond, so that runoff flows to the lowest corner, where the plant is placed. The usual dimensions are 5-10 m in width and 10-25 m in length. Small runoff basins can be constructed on almost any gradient, including plains with 1-2 % slopes. They are most suitable for trees. The soil should be deep enough to hold sufficient water for the whole dry season.
