The proper management of water resources is a key aspect of soil conservation in arid and semiarid environments, where any irrigation activity is structurally and deeply related to the understanding of soil hydrological behavior. In these areas, irrigation should be regarded to as an axle for oases and an effective defense against desertification. Its importance goes beyond the technological aspects, often being traditional irrigation a cultural heritage, which requires to be faced with an (at least) interdisciplinary approach which involves also humanities. On the other hand, improper practices may dramatically contribute to soil degradation. As an example irrigation may lead to soil salinization, with dramatic fallout on agricultural productivity, and overgrazing may lead soil to compaction, with negative effects on the soil capability of water buffering.

This session welcomes contributions ranging from the understanding of the soil hydrological behavior and of the mass fluxes, through the soil, in arid and water—scarce environments and also under stress conditions (e.g. water shortage, compaction, salinization), to the interaction between soil hydrology and irrigation, and to the design of irrigation systems in arid districts and oases. Particular attention will be given to the maintenance and improvement of traditional irrigation techniques as well as to precision irrigation techniques, also with local community involvement. Interdisciplinary contributions, which deal with different aspects and functions of the link between soil hydrology and irrigation techniques in arid environments, are encouraged.
