Group Description

President Lee in his Newsletter 2007/1 editorial mentioned about top 10 emerging technologies in the irrigation and drainage sector. During discussions in the Forum 5 Kick-Off with water related agencies a suggestion came up for the creation of a new ‘E-Forum’ which can debate on the proposed ‘top 10 technologies’.

Top Ten Technologies in Irrigation and Drainage
(1) Farmer controlled water supply, or total channel control or downstream control of canals; call it what you will, but essentially an extension of the control that came with groundwater, applied to surface sources and large systems; (2) Emitter delivery systems for precision irrigation and for undulating terrain, not just through drip systems but also through centre pivots, especially those that can be moved from centre to centre, and with sweeps programmed to serve typical farm blocks. Such technologies can bring irrigation to areas previously thought capable only of purely rainfed production; (3) Wetting front indicator, a technology recognised for its outstanding potential by a WatSave award, but not yet widely appreciated; (4) Drain controllers, also exampled by WatSave awards, for their capability to improve control of soil moisture and stimulate sub-irrigation; (5) Wetting-drying rice, another important water saving technology that WatSave has recognised in its widespread application in China; (6) No-till (NT) or minimum tillage technologies already used to conserve erodible soils and nutrients, and save fuel, but which can also conserve water in irrigated as well as rainfed production; (7) Fresh-saline irrigation, where saline and brackish water is used for part of the growing period without much loss of yield or detriment to the soil structure; (8) Salt and drought tolerant food crops, perhaps used in conjunction with 7, or independently, especially where irrigation is ephemeral or only supplementary; (9)..........
