Dear Colleagues,

Water plays a fundamental role for agricultural production and plays an important role in food security. Irrigated agriculture represents 20% of the total cultivated land and contributes of 40% percent of the total food produced worldwide. Irrigated agriculture is, on average, at least twice as productive per unit of land as rainfed agriculture, thereby allowing for more production intensification and crop diversification. Due to population growth, urbanization, and climate change, competition for water resources is expected to increase, with a particular impact on agriculture. Irrigation monitoring is of great importance in agricultural water management to guarantee better water use efficiency, especially under changing climatic conditions and water scarcity. In that context the evolution of remote sensing techniques and availability of data from different platform (Ground-Based, UAV-Based, Satellite-Based) in recent years, has opened new perspectives for supporting sustainable water resources management. A great contribution of Remote Sensing on irrigation monitoring is to provide detailed spatial/temporal information of the dynamics of the irrigated areas and the key elements of wich irrigation depend like crop Evapotranspiration (ET) and Soil Moisture (SM). This information would be helpful for supporting policy makers in the formulation of strategic agricultural plans to increase the efficiency of water use in agriculture.

The purpose of this Special Issue is to identify current research trends and key issues relate to water resource management in agriculture. We welcome novel research, reviews covering all irrigation related topics. We are especially interested in recent integrated water resources research using data fusion techniques, combining different sources (e.g., multi/hyperspectral sensor, optical/microwave, UAV with ground measurements), for retrieve ET constituents' parameters (such as land surface temperature, LAI, crop height, and albedo), and SM component (e.g., vegetation index, soil backscattering model, roughness and vegetation effects of radar signal).

The topic “Multi-Source Remote Sensing Data for Water Resource Management in Agriculture” invites high-quality papers focused on the design and development of methods, algorithm, strategies, and new technologies for water resource management and development impact assessment using multi-source remote sensing technologies under land use and climate changes. Potential topics include, but are not limited to:

• Mapping irrigated areas;
• Evapotranspiration mapping;
• Soil Moisture mapping;
• Synergy between radar and other sensors for SM and ET retrieval;
• Role of remote sensing in supporting water policy;
• Application of remote sensing techniques to estimate water stored volume in artificial reservoir
