A soil and water conservation and pasture management technology implemented through area closure, fencing, and installation of check dams to control erosion and rehabilitate degraded rangelands.
The micro half-moon catchment (Bila Bilo) of Beyra is a soil and water conservation technology that harvests runoff, reduces erosion, and improves water infiltration in dryland areas. By capturing sediments and retaining soil moisture, it creates fertile micro-sites that support vegetation regeneration, land restoration, and climate change adaptation.
Rock check dam is a small, low barrier built across gullies, or seasonal waterways to Reduce erosion, Increase water infiltration into the soil, etc Check dams are often used to restore degraded land, improve pasture, and support year-round grazing by helping water soak into the ground rather than washing soil away.
Contour trenches for the cultivation of almond trees, and contour strips for cereals are types of rainwater harvesting structures. They are designed to capture runoff, reduce erosion, and enhance soil moisture—thereby improving land productivity and supporting climate-resilient agriculture in lowland dry areas.
Gradoni orchard terraces are intermittent strips of contour-based structures separated by catchments of about 10 metres. They are designed to capture and hold rainwater, reduce erosion, and improve conditions for the cultivation (in this case) of almond and pistachio trees, thereby enhancing land productivity and climate resilience in dryland areas.
Tree plantation pits are water harvesting structures which capture rainfall runoff for trees and shrubs. They receive supplementary water until seedlings are well established. Species planted are indigenous, and provide both shade and honey.
Cross-wadi structures are built from local stone to slow the flow of runoff. These water harvesting walls reduce the severity of storm flow, causing sedimentation and a rise in the water table level. Productive trees can be planted as a result.
An integrated community-led initiative has been established to restore the degraded forests in Paktya province. This initiative focuses on setting up nurseries and incorporates both indigenous and scientific knowledge to cultivate climate-resilient species, such as Cedrus deodara and Pinus gerardiana. These efforts have enhanced the community’s knowledge and skills in sapling production and transplantation, leading to significant improvements in the productivity of these key species, which holds substantial ecological, social, cultural and economic values.
Springshed revival through trenches and check dams is associated with a nature-based solution approach to reviving more than 20 springsheds. These were widened with the occasional construction of check dams to prevent rill erosion from the newly revived spring waters.
Low-cost plastic-lined water harvesting ponds collect and store rain and overland flow water for agricultural and domestic purposes in the dry season. They are both economic and efficient.
The half-moon technique is designed to enhance water retention and soil infiltration. This is achieved by constructing crescent-shaped mounds around the base of trees. A compass can be used to outline a semi-circle with a diameter of 4 meters. The soil within this outlined area is then excavated and used to form a ridge.
Mechanical bench terraces are a landscaping technique employed on sloping terrain. These are essentially mechanically constructed earthen levees or embankments established along contour lines.
A double basin masonry check dam is a physical structure that helps to stop gully formation or further development of gullies in dry valleys. It rehabilitates small to a medium-sized deep gullies that are eating into the heart of adjacent land.
Biochar is a carbon-rich, solid material derived from a wide range of biomass or organic waste through a thermochemical method. It is an organic charcoal material that is the final product of pyrolysis, or high-temperature burning of agricultural biomass without oxygen. Surplus crop residues, agricultural waste, and wood from sustainable sources are used as feedstock (raw material). Such biochar production is linked with agroforestry plantation and agriculture to improve soil health and ensuring sustainable feedstock availability.
Individual dry-stone basins are a traditional runoff water collection technique built in dry stone around the trunk of trees, mainly olive trees.
Detention ponds are artificially excavated basins that collect stormwater runoff and eroded sediment from the upstream catchment. The water stored in these ponds is slowly released into a water body or it infiltrates into the groundwater – or both. Their primary functions are flood control, erosion control and water quality improvement.
Retention ponds (e.g. flood storage reservoirs, shallow impoundments) are water bodies, storing water to attenuate surface runoff during rainfall events. They provide storage as well as improving water quality. Retention ponds may also be used for irrigation of farmland.
Microcatchment water harvesting captures, stores and allows safe overflow of excess surface runoff collected during heavy rainfall events. The intercepted and deep-infiltrated water enhances soil moisture at/around the microcatchment structure. This eventually boosts plant productivity in dry areas, mitigates land degradation, and benefits the local farming communities’ livelihoods
Sediment capture ponds are constructed and located along networks of ditches which drain watersheds. They slow the velocity of water and cause the deposition of suspended materials. These ponds help to avoid sediment accumulation in the ditches themselves, and can decrease sediment and nutrient pollution of surface water bodies downstream.
Weeds and crop residues laid in bands across the slope of annual crop fields to conserve soil and water, and to incorporate organic matter into the soil after decomposition.
Fish farming, commonly referred to as aquaculture, is one of the common practices promoted by small, medium and large scale farmers in Amuru District, Northern Uganda. Labour, hoes, wheelbarrows, spades and slashers are used for establishment. The technology is established on a gently sloping physical environment located mainly at the valley bottom for purposes of obtaining food security and household income.
Spring ground water reservoir to supply water for the fish pond during dry season to be harvested throughout the year.
CF basins are constructed in the field to act as water storage containers. Water is conserved within the basins and plants can survive with this conserved water during periods of little rainfall and dry spells.
Plastic tanks of 50 to 100 liters of water with taps are placed on high platforms. Perforated plastic tubes allow water to flow and drip irrigate vegetable patches. Home gardening, once established can be carried out throughout the year.
Cisterns are water collection structures which form part of a cultural heritage dating back some 2000 years. While cisterns are commonly used to store drinking water, in the sloping fields of Tarsus they serve as a form of water insurance structure for orchards during dry periods.
Des buttes en terre sont accumulées de manière à infiltrer l'eau de pluie dans les point ou les arbres fruitiers poussent, ceci afin de diminuer la demande en eau d'irrigation par goutte à goutte.
The Al Yakloum pond collects runoff from a local catchment and water is led through a channel system alongside a farm road. Sandy particles are captured in a sediment trap before runoff enters the pond. The pond provides water to approximately 5 ha of orchard - which is irrigated through a precision system.
