GIS based solar resource analysis for irrigation purposes: Rural areas comparison under groundwater scarcity conditions

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