摘要

在全球政策中,灌溉基础设施升级日益被视为解决水资源短缺和农业生产力低下问题的办法。然而,这些技术“修复”可能最终被证明是危险的捷径,无助于解决灌溉者、土著居民、环保组织和当地社区对水资源短缺、获取、安全和可持续性的担忧。在缺乏透明和严格的治理保障的情况下,灌溉效率的提升可能导致更高的用水量和需求,并最终加剧水资源短缺。升级后的灌溉系统还倾向于收集回流并将其重新分配给“高价值”的消费用水,可能取代其他用户和用途,包括土著人民。在本文中,我们批判了目前治理灌溉效率的方法,使用水正义的视角来确定四个关键见解及其对治理的影响。我们提出了新的治理途径和方案,考虑到水文现实和全方位的水需求和需求。

Delivering global water security: Embedding water justice as a response to increased irrigation efficiency
Increasingly, irrigation infrastructure upgrades have been regarded in global policy as a solution for both water scarcity and low agricultural productivity. However, these technical “fixes” may ultimately prove to be dangerous shortcuts that do little to address the concerns of irrigators, Indigenous People, environmental groups, and local communities about water scarcity, access, security, and sustainability. In the absence of transparent and rigorous governance safeguards, irrigation efficiency upgrades can result in higher water consumption, demand, and ultimately, increased water scarcity. Upgraded irrigation systems also tend to capture return flows and redistribute them to “high value” consumptive water uses, potentially displacing other users and uses, including Indigenous Peoples. In this article, we critique current approaches to governing irrigation efficiency, using a water justice lens to identify four key insights and their implications for governance. We propose new governance pathways and options that take into consideration hydrological realities and the full range of water demands and needs.
