Old flat terraces were built in accordance with the contour lines and surrounded by stones to create a suitable environment for the growth of crops, slope stabilization and reduce the risk of runoff and increasing water harvesting.

V shaped catchment fences are used to stabilize gullies and prevent soil sediments from being removed by surface rain water runoff. It consists of planting izote (Yucca sp.) to create a V shaped fence around a gully.

Trenches commonly referred to as contour trenches and running perpendicular to a slope increase water infiltration and reduce soil erosion as a way of conserving soil.

A contour trench and pit are an excavated ditch/pit along a uniform level across the slope of land in the top portion of catchment to trap runoff water.

Windbreaks of poplar trees (Populus nigra pyramidalis) are a major agroforestry system in irrigated agriculture across Central Asia. Such windbreaks reduce the overall water consumption of irrigated agriculture by 10-20% and increase farm income by 10-15%.

Ox-ploughed furrow micro-catchments are intentionally built as part of seedbed preparation to harvest rainwater. Commonly used in dryland environments, the micro-catchment prolong water availability for seed germination and growth and development of the emerging seedlings.

The technology of cultivating agricultural crops with the use of hydrogels ensures optimal soil moisture and plant nutrition by accumulating soil water and nutrients and gradually releasing them to the plants, thereby increasing crop yields and improving harvest quality.

Grass strips are spaced at regular intervals along contour lines. These strips are not ploughed during soil preparation, and Brachiaria grass is used to form barriers to reduce water-induced erosion. Over time, the plots evolve naturally into terraces.

Accumulating coarse woody debris in stream beds reduces flow velocity and levels of flood peaks. As a consequence the speed and energy of water flow is reduced, allowing greater deposition of sediments. In addition the technology has ecological advantages.

Mechanized Raised Beds (MRB)-technology improves livelihoods because raised beds lead to significantly reduced costs (30% less water, 20-40% less nitrogen fertilizer) and higher wheat yields increased by 20-30%. MRB-technology helps to do more with less.
