“…In both cases, high water demand and inefficient irrigation methods should be improved, proposing alternative solutions in line with the hydrological cycle characteristics of the area. Additionally, unsustainable irrigation patterns should be modified, promoting new policies from government and organizations responsible for the care of water resources [41]. In this way, the groundwater levels have dropped dramatically during the last years, with scarcity problems and difficulties to reconcile agriculture with the environment.…”

During the past decade, most governments have been promoting energy efficiency programs and the integration of renewable energy sources into the majority of energy uses. Among the diferent sectors, the agricultural sector is becoming a more active participant to reduce fossil fuel dependence and improve environmental sustainability. Indeed, agriculture usually combines both a high energy demand and water problems associated with over-exploited aquifers, providing great potential and remarkable opportunities to change the energy mix and maximize the use and integration of natural resources in a rational way. Considering this framework, the present paper describes and compares the solar resource integration and its effects on agricultural pumping purposes in two Mediterranean countries, Spain and Morocco, with significant differences in terms of energy mix, climatic conditions and energy policies. As a novel contribution in this paper, we propose the use of GIS to analyze the spatial and temporal variability of the solar resource through real data of both locations, as well as to study groundwater resources. With this aim, two technical proposals for irrigation purposes are compared in terms of environmental benefits, CO 2 emissions and agriculture energy model changes: diesel equipment and photovoltaic system. Results based on solar radiation resource, pumping requirements and aquifer depth are included in the paper.

Computer models nowadays have become part of the common toolbox used in groundwater studies, concerning subsurface flow and transport processes. Analytical and numerical models are developed as solutions of differential equations, which are derived from basic principles and conservation laws. There are different finite discretization techniques to implement approximate solutions for differential equations and boundary conditions on a computer. Current modeling software, used by modelers for their work, not only includes solvers for equations but also various tools for pre‐ and postprocessing. The connections with other software, for surface water, for multispecies, for multiphysics, geo‐information systems, optimization, or parameter estimation are the current frontier of further development.
