Drip irrigation is an efficient method of providing irrigation water directly into soil at the root zone of plants and thus, minimizes conventional losses such as deep percolation, runoff and soil.
Drip 90 Improved Irrigation Technologies A number of technologies have been developed to apply water more uniformly without excessive waste. Among these are systems such as low-pressure center pivot, LEPA (Low-Energy Precision Application), surge, and micro-irrigation. These improvements may require capital.
Drip irrigation is an ideal solution for irregular or small areas. Inline drip irrigation limits the potential for liability by reducing or eliminating overspray on buildings, walkways, roadways, and other trafficked areas.
Main-tenance costs are often lower due to reduced overspray, runoff, erosion, compaction, water staining, and property damage. Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates ( litres/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or is applied close to plants so that only part of the soil in which the roots grow is wetted (Figure 60), unlike surface and sprinkler irrigation, which involves.

Between and26 SSA countries experienced at least 6 droughts, and 14 of them experienced at least 10 droughts, precipitating food crises that resulted in hundreds of thousands of deaths over the period (6, 7).Such famines continue to occur against a backdrop of widespread chronic malnutrition—in the forms of calorie, protein, and.
The International Commission on Irrigation and Drainage is dedicated to enhancing the worldwide supply of food and fibre for all people by improving water and land management and the productivity of irrigated and drained lands through appropriate management of water, environment and application of irrigation, drainage and flood management techniques.
Irrigation Technology Advances New technology is regularly revealed as environmental needs change and the U.S. takes a harder look at water consumption. Farmers already control their irrigation systems with full-color touchscreen displays, one of a number of advanced irrigation controller technology options.
More thanof iDE’s low-cost drip systems have been sold in India, Nepal, Zambia and Zimbabwe,” according to National Geographic. There are several international initiatives to spread drip technology.
The International Atomic Energy Agency has signed 19 countries onto its technical cooperation project to promote drip irrigation systems. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'.
Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language.
This can be attributed to the improved soil water availability for growth and the ability of the irrigator to match crop water demands efficiently. Geographical considerations Surface drip irrigation for tree and vine crops is suitable worldwide. Two factors should be considered in determining whether drip irrigation is appropriate.
