Water sustainability under climate change and increasing demand: a one water approach at a watershed scale

在本世纪初，水将成为加拿大最重要的生态危机（Schindler 2001）。人们一再建议以流域为基础的水管理办法来解决水的可持续性问题。然而，这种办法很少得到充分实施。在流域尺度上全面了解水资源总量（气候、地表水、浅层和深层地下水等）及其相互作用是一个主要障碍。我们建议从单一水的角度来评估位于不列颠哥伦比亚省半干旱南部内陆奥肯那根盆地的深溪流域（306平方公里）在气候变化和不断增长的社会经济需求驱动因素（农业和人口）下的流域可持续性。适宜的流域规模和使用者之间显著的用水冲突造就了这一流域

Water will become Canada's foremost ecological crisis early in this century (Schindler 2001). A watershed based approach for water management is repeatedly suggested to address water sustainability issues. However, full implementation of such an approach is seldom realized. Achieving a full understanding of total water resources (climate, surface water, shallow and deep groundwater etc.) and their interactions at a watershed scale is a major barrier. We propose to take a one-water perspective to evaluate watershed sustainability under climate change and increasing socio-economic drivers of water demands (agriculture and population) in the Deep Creek watershed (306 km2) located in the Okanagan basin of the semi-arid southern interior of British Columbia. The suitable watershed size and significant water conflicts among water users make this watershed
