Here we present a new framework to guide eco-hydrological restoration of saline lakes and build their resilience to climate change by optimizing agricultural land use and related water withdrawals. The framework involves four steps: 1. selection of global circulation models for the basin under study; 2. establishment of a hydrological balance over the lake’s area to estimate the amount of water required for its restoration; 3. water allocation modeling to determine the water available for restoration and allocation of the remaining water across different users in the lake’s basin; and 4. basin-scale optimization of land use and cropping patterns subject to water availability. We illustrated the general applicability of the framework through the case of the second largest (by volume) hyper-saline lake globally, Lake Urmia, which lost 96% of its volume in only 20 years, primarily as a result of upstream water withdrawals. Through the application of the framework, we estimated the amount of water needed to restore the lake, either fully or partially, and proposed a sustainable land-use strategy, while protect farmers’ income in the basin. Considering future climate change projections under two representative concentration pathways (RCP) 4.5 and 8.5, we found that an average annual surface inflow of 3,648 Mm3 (∼70% increase in RCP 4.5) and 3,692 Mm3 (∼73% increase in RCP 8.5) would be required to restore the lake by 2050, respectively. This would require the respective conversion of 95,600 ha and 133,687 ha of irrigated land to rain-fed cropland or grassland across the basin by 2050. The proposed framework can be used for building resilience to climate change and mitigating human-induced threats to other declining saline lakes.

The temporal variations of supplied water to different demands are assessed as provisioning hydrological ecosystem services. Then, three agricultural drought management policies have been defined for each water supply-demand alternative to reduce the irrigation water and cultivated area of the agricultural demand nodes during droughts. In addition to the net primary productivity criterion (NPP) and economic profit, the ecological condition of the system has been evaluated as an ecosystem services-based criterion. To prioritize and select the best water resources management (WRM) scenario(s), a game theory-based hierarchical evidential reasoning (ER) technique with multiple decision-makers has been used. The proposed methodology has been applied to the Urmia Lake basin, which is the largest saline lake in the Middle East. The grade-based values of the criteria have been used to compare the WRM scenarios. The results show that a scenario that includes supplying 100% of the lake's water demand has the highest priority. This scenario also suggests reducing the cultivated area of dominant crops and using deficit irrigation practices.

Situation Agricole NATURE CONSERVATION AGRICULTURAL PRACTICES PRATIQUE AGRICOLE SOCIAL REPRESENTATION REPRESENTATION SOCIALE CLIMATIC CHANGE TERRITORY TERRITOIRE GEOGRAPHY WATER LAKES WATERSHEDS BASSIN VERSANT RIVERS FORECASTING HISTORY BURGUNDY BOURGOGNE Résumé : Les natures sont socialement constituées. Dans une perspective de géographie de l'environnement, cet article aborde deux formes d'interprétation des relations entre Homme et nature : les représentations et l'anticipation du futur. Comment des agriculteurs se représentent-ils les objets de nature définis par d'autres comme lac, rivières et bassins versants ? Différemment. Le rapport des agriculteurs à la nature est singulier. Leur regard et leurs représentations se forgent à travers des actes et des pratiques matérielles. Mais le temps modifie ces représentations. Le changement climatique vient bousculer les représentations établies de la nature. Il amène à envisager l'avenir en rupture avec le passé, c'est-à-dire pour le géographe trouver des méthodes pour aborder le futur. A la frontière entre recherche et action, l'imagination du futur peut être un ressort pour penser de manière renouvelée les relations entre les groupes sociaux et la nature.
