This paper describes a decision support system (DSS) that was developed to improve planning and management for the large irrigation schemes in the Alentejo region of Portugal.
Information was only available in districts located in large irrigation projects, accounting for 58% of the irrigated area in the basin.
Because the use of WV2 images is not financially viable for operational use in very large irrigation schemes, the study concludes with some guidelines on the spectral and spatial requirements of images when monitoring salt accumulation in irrigation schemes with similar conditions.
However, following successful tests of growing Egyptian cotton in West Africa during World War I, Émile Bélime began to campaign for the construction of a large irrigation system along the Niger river.
Nevertheless, the final framework is generic in nature, being suitable for planning and policy evaluation in other large irrigation schemes.
Boys from Zanzur, a village on the edge of Tripoli, which has a large irrigation system, have been trucking water to the thirsty city centre for nothing.

The economy and health of the area is linked to the Great Ruaha River, which serves as a critical source of fresh water for people, livestock, and wildlife; hydropower-generated electricity for Tanzania's national grid; and irrigation for large- and small-scale farming operations (Newmark 2010; Walsh 2012).
