Irrigation, soil and fertilizers are key factors to feed world population in the next decades. Within this framework, best management irrigation practices will play an important role to maintain and improve soil sustainability and to meet the standards dictated by the European Directive. Despite the increased production and diversification, the sustainability of irrigation is questioned. This is largely due to its sometimes detrimental effect on the environment and associated economic costs. In consequence, soil productivity could be drastically reduced and thus, crop productivity. Likewise, erosion will be reinforced and ecosystems affected as well. In addition, fertilizers and contaminants applied with irrigation water move through the soil, and very often reach the water table enhancing the risk for human and animal health.
On the other hand, quality of irrigation water is reduced each day and, in some locations wastewaters are used for that porpoise. This could result in soil salinity, especially in heavy soils, and would constrain soil sustainability. For irrigation, each soil type must be considered relative to some soil specific characteristics, especially physical, since irrigation sustainability is associated to particular requirements for soil management.
To understand and assess the effect of irrigation and fertirrigation practices in soil sustainability and its productivity.
To promote better irrigation practices in order to maintain soil biodiversity and to improve or restore natural ecosystems.
To design precise irrigation systems and/ or water-energy-irrigation systems
