Agriculture is by far the largest water use at global level. Irrigation of agricultural lands accounted for 70% of the water used worldwide. In several developing countries, irrigation represents up to 95% of all water uses, and plays a major role in food production and food security. Future agricultural development strategies of most of these countries depend on the possibility to maintain, improve and expand irrigated agriculture
On the other hand, the increasing pressure on water resources by agriculture faces competition from other water use sectors and represents a threat to the environment.
Water is a resource that may create tensions among countries down and upstream. Irrigated agriculture is driving much of the competition since it accounts for 70-90% of water use in may of these regions.

Reuse of water for irrigation

Water reuse for irrigation is a normal practice worldwide.
However the use of recycled water for irrigation may have some adverse impacts on the public health and the environment. This will depend on the recycled water application, soil characteristics, climate conditions and agronomic practices. Therefore it is important that all these factors are taken into account in the management of recycled water.

The water quality used for irrigation is essential for the yield and quantity of crops, maintenance of soil productivity, and protection of the environment. For example, the physical and mechanical properties of the soil, ex. soil structure ( stability of aggregates) and permeability are very sensitive to the type of exchangeable ions present in irrigation waters.
