SEVAI trains the rural youth in conjuctive use of water for iirrigation

Amoor youth trained in conjunctive use of water for irrigation

SEVAI trains the rural youth in the Irrigation Technician program. SEVAI Irrigation Technician program trains the rural youth for design, installation, repair, upgrade, maintenance, monitoring and programming of irrigation systems for landscapes, nurseries, agriculture. SEVAI provides rural youth with the necessary skills to design, install, main­tain, troubleshoot, repair and program irrigation systems in Amoor village. SEVAI trainer Murugan enlightens the trainees, “Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agriculture crops maintenance of Irrigation system, and contouring of disturbed soils during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants, suppressing weed growing in grain fields and helping in preventing soil consolidation In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or drying. Irrigation systems are also used for dust suppression, disposal of sewage and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area. Currently, the advent of diesel and electric motors led to systems that could pump ground water out of major aquifers faster than it was recharged, various types of irrigation techniques differ in how the water obtained from the source is distributed within the field. In general, the goal is to supply the entire field uniformly with water, so that each plant has the amount of water it needs, neither too much nor too little. The modern methods are efficient enough to achieve this goal. In surface irrigation systems, water moves over and across the land by simple gravity flow in order to wet it and to infiltrate into the soil. It is often called flood irrigation when the irrigation results in flooding or near flooding of the cultivated land. Where water levels from the irrigation source permit, the levels are controlled by dikes, usually plugged by soil. This is often seen in terraced rice fields, where the method is used to flood or control the level of water in each distinct field. Localized irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. The moisture stored in the soil will be used thereafter to grow crops. Successful agriculture is dependent upon farmers having sufficient access to water. However, water scarcity is already a critical constraint to farming. With regards to agriculture, food production and water management as an increasingly issue that is fostering a growing debate. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function effectively. -Govin
