DocumentRainwater harvesting systems for tomato growing in Uganda 2017
Also available in:
No results found.This technology describes utilizing rooftop water harvesting facilities to increase the availability of water for domestic use and irrigation of backyard tomato gardens. This measure allows small-scale farmers to harvest rainwater from roofs and store it in tanks, ensuring tomato 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. -
DocumentCompendium on Rainwater Harvesting for Agriculture in the Caribbean Sub-region
Concepts, calculations and definitions for small, rain-fed farm systems
2014Also available in:
No results found.The purpose of this document is to provide a practical tool to train and build human capacity in the Caribbean sub-region in the practice of rainwater harvesting. Application of rainwater harvesting techniques will produce measurable improvements in livelihood and household food security, generated by access to reliable water resources for irrigation. The document is targeted to agricultural smallholders operating on two hectares of land or less, as well as backyard gardeners and school gardenin g projects. It describes simply, but carefully the relationships between plants, soil, water, climate and rainfall, and on-farm rainwater harvesting. The document uses calculations and tables to explain the concepts, charts and drawings to illustrate them. Furthermore, both metric and imperial systems of measurement are used throughout to facilitate practical application of the knowledge gained by users. It includes important definitions and reference tables to provide added guidance to users. A dditionally, each example of a rainwater-harvesting system is illustrated by the relevant drawings and/or photographs. In a step-by-step approach to knowledge-building, the document addresses the following five areas: (a) design rainfall; (b) the catchment area and storage design; (c) reference crop evapotranspiration and crop water requirements; (d) managing effective rainfall and cumulative storage; and (e) rainwater harvesting systems suitable for the Caribbean sub-region. -
DocumentFeasibility Study of Rainwater Harvesting for Agriculture in the Caribbean Subregion 2014
Also available in:
No results found.The document provides the information necessary to assist in the design of or strengthen national programs to build individual farmer or community capacities in rainwater harvesting. Farmers need not have prior knowledge in the use of the technology. However Extension Officers will require the necessary inputs from among technical officers with an understanding of the statistical, physiological and technological processes involved. These include practices in evaluation of suitability of series r ainfall data, probability analysis of series data and simple engineering works suited to catchment and storage requirements.
