The proper management of blue and green water is vital for sustainable livelihoods and agricultural practices around the world. This is especially true in drylands, where any productive activity is deeply related to the understanding of soil hydrological behaviour, and irrigation is both a pillar of agroecosystems and a defence against desertification, but also in temperate or humid lands which can experience variations in the hydrological cycle and be prone to water scarcity due to climate change.
Improper practices, which are not able to cope with climate-induced variability and anomalies, may in fact contribute to soil degradation and depletion of the available water sources. For example, incorrect irrigation techniques may lead to soil and groundwater salinization, with dramatic fallout on agricultural productivity, while overgrazing may lead to exploitation of vegetation cover, soil compaction, and adverse effects on the soil capability of water buffering. On the other hand, the role of irrigation goes beyond the technological aspects: traditional irrigation is a cultural heritage, which is often structurally resilient, and which needs to be faced with an interdisciplinary approach involving humanities.
This session welcomes contributions with a specific focus on:
- The understanding of the soil hydrological behaviour and of the mass fluxes through the soil in drylands and environments under actual or projected stress conditions (e.g. water shortage, compaction, salinization)
- The interaction between irrigation and soil hydrology including deep drainage
- The analysis of the bio-geo-physical and social dynamics related to rainfed and irrigated agriculture in both arid and non-arid areas and oases, including the use of non-conventional waters (e.g. water harvesting), and managed aquifer recharge systems
- The management of rangeland areas, including their restoration
This session is co—sponsored by the International Commission on Irrigation and Drainage (ICID, to be confirmed) and the International Center for Agriculture Research in the Dry Areas (ICARDA, to be confirmed).
