Field of Work Irrigation
Irrigation is recommended in all cases where agriculture is not profitable or not possible due to too little water. This is often the case in semi-arid and arid areas.
Irrigation provides an opportunity to increase crop yields and thus to become (more) independent of food aid. With sufficiently strong irrigation the salting of soil can be also be avoided. Already salinized soil can become salt-free again.
In some cases, drainage is additionally required for irrigation. That is the case, for example, when the seeped water from irrigation and rainfall accumulates in water-impermeable soils and layers.
