Maintaining sustainable development in semi-arid regions is a complex task due to scarce precipitation, with notable temporal and spatial variations that complicate planning and proper management of water resources. Most of the water extractions from the aquifers in southeast Spain are carried out to supply a growing agricultural sector and increasingly successful tourism, which is the case of the Sierra de Gador-Campo de Dalias system. Savings, reutilization and awareness among water users are essential elements in any sustainable water policy. Some of the possible solutions proposed that offer low environmental impacts include certain infrastructure works, such as dams, ditches or recharge in gravel pits. Also, desalinization plants constitute a technical alternative in theory but involve high costs. The integration of all these resources, together with their proper management, is necessary to ensure the future water supply and economic growth in the region, safeguarding the state of its aquifers that are currently intensely overexploited.

西班牙东南部 Sierra de Gador-Campo de Dalias 系统的地下水可持续性战略

由于降水稀少，时空变化显着，使水资源的规划和妥善管理变得复杂，保持半干旱地区的可持续发展是一项复杂的任务。西班牙东南部含水层的大部分水提取用于供应不断增长的农业部门和日益成功的旅游业，例如 Sierra de Gador-Campo de Dalias 系统。节水、再利用和用水者的意识是任何可持续水政策的基本要素。提出的一些对环境影响较小的可能解决方案包括某些基础设施工程，例如水坝、沟渠或砾石坑中的补给。此外，海水淡化厂在理论上构成了一种技术替代方案，但成本高昂。所有这些资源的整合，
