Drip irrigation (ISRAEL)
Subject category: Agriculture
Israel, with scarce agricultural land and precious little by way of fresh water supplies, needs to maximize its food output per unit of land while minimizing water use. As part of its drive to cut down on water use, the government chose to promote drip irrigation, which is more expensive than most other irrigation methods. However drip irrigation in terms of water use efficiency is a desirable irrigation method in a country like Israel, where desalination is used to distill fresh water from sea water .
Drip irrigation is the slow drop-by-drop, localized application of water at a grid just above the soil surface. There are also subsurface drip systems, in which drip irrigation laterals are buried 20-60 centimeters below the soil surface. Drip irrigation saves water by reducing the size of the wet soil surface, thus decreasing the amount of direct evaporation and excess percolation through the root zone. Unlike sprinklers, drip irrigation is practically unaffected by wind conditions, nor is it affected by soil surface conditions. Soil is maintained in a continuously moist condition. Nutrients can be applied through the drip systems, thus reducing use of fertilizers and improving the quality of returned water. Increases in water use efficiency in drip irrigation, compared to conventional basin/furrow irrigation, are attributed to both water savings and the increase in yields resulting from favorable soil moisture and nutrient regimes.
Israel has achieved a modernization of irrigation techniques and increased irrigation efficiency by introducing drip systems and computerized automatic water control. The improvements over the past years have made it possible to significantly increase both the area under irrigation and agricultural production, without increasing water use. The accompanying table illustrates the significant reduction of water requirements per unit of production in 1984, due mainly to application of modern irrigation technologies, compared with conventional irrigation used in 1970. For example, the reduction of water demand is about 60 percent for the production of potatoes, apples and bananas and about 30 percent for avocados and cotton.

By choosing drip irrigation, Israel has incurred significant installation and maintenance costs. Although the initial investment cost of drip irrigation is relatively high compared to other irrigation methods, in Israel the unit cost of fresh water supply and the opportunity cost of water wastage is much higher than the rest of the world. Another reason why the high cost was justified was because the availability of high technology in the coutry enabled Isarel to apply drip irrigation widely with significant water savings that more than offsets these costs.

Propostas Israelitas em Camp David – Julho de 2000
Será estabelecido um Estado Palestiniano em territórios da WB e Gaza de acordo com as seguintes condições:
não terá um exército com armas pesadas
não fará alianças com outros Estados sem a aprovação de Israel e não permitirá a introdução de forças estrangeiras a ocidente do rio Jordão.
Israel manterá o direito a colocar tropas na WB se existir ameaça de invasão de Oriente
A aviação israelita manterá o direito a utilizar livremente o espaço aéreo palestiniano
Israel poderá instalar “early warning stations” nas montanhas em redor do vale do Jordão e também em outras áreas
O controlo de fronteiras será feito pelos palestinianos mas com a presença das forças de segurança israelitas
Israel manterá a gestão dos recursos hídricos na WB e aprovará uma quota limitada para os palestinianos
Israel “alugará” algumas zonas no vale do Jordão ou manterá soberania temporária sobre estas por período até 25 anos
O problema dos refugiados palestinianos será resolvido da seguinte forma:
Israel não aceitará nenhuma responsabilidade civil ou legal na sua deslocação
Será permitido o retorno de 100.000 refugiados por “razões humanitárias” (reunião familiar) e isso significará o cumprimento da Res. 194 das NU
O nº de refugiados cujo regresso à Palestina será autorizado nunca será superior a 500.000
Um fundo internacional compensará os restantes e também refugiados judeus
