Rainwater harvesting systems for cabbage growing in Uganda

This technology describes utilizing rooftop water harvesting facilities to increase the availability of water for domestic use and irrigation of backyard cabbage gardens. This measure allows small-scale farmers to harvest rainwater from roofs and store it in tanks, ensuring cabbage production also during the dry season, when it would be otherwise impossible.
The combination of rainwater harvesting with other good practices (e.g. mulching, manuring) help increase productivity while reducing soil erosion, eventually strengthening the resilience of farmers to the impact of dry spells.

Rooftop water collection, drip irrigation and plastic mulching in home garden conditions in drought prone areas of Cambodia

In Cambodia, drought can have different impacts: delay of rainfall onset in early wet season, erratic variations of rainfall onset, early ending of rains during wet season, and longer dry spell in July and August. This technology describes three different technologies and analyses the costs and benefits of their combined application: rooftop water harvesting, drip irrigation and plastic mulching in home garden conditions. As a result of the combined application of those good practices (GPOs), the resistance against drought is increased and a second cropping period is possible. The GPOs have been tested and validated in 19 Farms in the Kampong Speu (3) and Oddar Meanchey (16) Provinces in Cambodia.

Rainwater harvesting systems for ntula/eggplant (Solanum aethiopicum L.) growing in Uganda

This technology describes utilizing rooftop water harvesting facilities to increase the availability of water for domestic use and irrigation of backyard ntula/ eggplant (Solanum aethiopicum L.) gardens.
This measure allows small-scale farmers to harvest rainwater from roofs and store it in tanks, ensuring ntula production also during the dry season, when it would be otherwise impossible.
The combination of rainwater harvesting with other good practices (e.g. staking, mulching, manuring) help increase productivity while reducing soil erosion, eventually strengthening the resilience of farmers to the impact of dry spells.

Improved rainwater harvesting for fodder shrub production and livestock grazing: the Vallerani micro-catchment system in the Badia of Jordan

The Central and West Asia and North Africa (CWANA) region is characterized by a wide variability in rainfall and temperature. In these areas, evapotranspiration largely exceeds the amount of rainfall, leading to droughts with low forage production and water availability. The concurrent increase in human population with the growing demand for meat has led to increased grazing pressures on rangelands and the exhaustion of their potential productivity.
The Badia in Jordan constitutes the largest part of the country. It encompasses approximately 72 thousand square kilometers, corresponding to 81 % of the total area of the country. Increased grazing pressure and cultivation of traditional and fragile grazing lands has led to severe degradation of the Badia rangelands.
Since the main limiting factors to growth of plants in the Badia are low precipitation, and poor soil quality, the little precipitation water can be collected by establishing micro catchments on the rangelands. The Vallerani System is an intervention strategy for soil regeneration that integrates technology, traditional techniques and the application of good cultural practices adapted to the local reality, to restore big surfaces of degraded arid and semi-arid rangelands. Its application allows pasture improvement, reforestation and the establishment of agro-forestry sites, thus also enhancing the socio-economic development of the local communities affected.
This practice explains the Vallerani System and highlights its benefits and limitations. The practical implementation of the system is described on the basis of an example of the Badia rangeland rehabilitation project, implemented by ICARDA within the first decade of the new millenium.

Rainwater harvesting for schools

Women and children are usually the main household collectors and users of water. Long walking distances from households to improved water sources make it difficult for them to access safe water. As a result, they resort to using inadequate and unsafe water sources such as unprotected self-dug wells and water holes, exposing themselves to diarrhea and other infectious water borne diseases. The water tanks ensure availability of safe water within communities, thus reducing the prevalence of infectious diseases such as diarrhea.

Roof top rainwater harvesting – Concrete Tank

Roof top rainwater harvesting – Concrete Tank - The roof top rain water harvesting system using a concrete tank was designed to improve household access to water for irrigation of kitchen garden plots during the hot and dry summer months.
A 16 cubic metre concrete tank situated in the shadow of the house constructed to retain rainwater that collects in the roof guttering. The purpose of the tank is to retain water to be used for drinking, sanitation and irrigation during the hot and dry summer months. The retained water allows for the irrigation of kitchen garden plots and more diverse crops, and hence should improve the livelihoods of households involved. There are three main elements to the construction of the rainwater harvesting system:
- the construction of a metal gutter on wooden supports around the perimeter of the roof
- the construction of a concrete pool in the shadow of the house;
- the provision of a connection pipe between the gutter and the pool.
