ABSTRACT

We propose the concept of ‘agri-vector water’ (AVW) to refer to water allocated to towns to maintain urban-based agricultural services that support rainfed farming in surrounding areas. AVW captures the idea that highly scarce ‘blue water’ can be productively used in this way to support rainfed ‘green water’ rather than be applied as consumptive irrigation, especially when the latter exacerbates water shortages during drought and dry seasons in arid and semi-arid regions. To illustrate, we present two case studies from Ethiopia.

农业用水：通过分配城市水来促进雨育农业，以支持城乡联系

摘要

我们提出“农业用水”的概念，指分配给城镇的水，以维持城市农业服务，以支持周边地区的雨养农业。AVW的想法是，可以以这种方式有效地使用高度稀缺的“蓝色水”来支持雨养的“绿色水”，而不是用作消耗性灌溉，尤其是当后者加剧了干旱和半干旱时期在干旱和干旱季节的缺水时干旱地区。为了说明这一点，我们提出了来自埃塞俄比亚的两个案例研究。
