Drinking Water Security Climate Change

项目摘要

The drinking water for more than 58% of the largest urban communities in Canada originates in forested watersheds. The health of Canada’s forests and the waters they supply is threatened by numerous pressures, including potentially severe threats from climate change that cause increasingly variable and deteriorated water quality. This can overwhelm treatment processes and push them beyond their design capacity, necessitating potentially cost-prohibitive changes in treatment to ensure provision of safe drinking water. The value of natural storage and filtration of water by global forests has been estimated at $4.1 trillion (US) and so, forested water resources are strategic priorities in Canada and globally. Thus, the delivery of safe drinking water—security—and its relationship to natural and anthropogenic activities in forested watersheds is a critical priority. Forest disturbances (e.g. wildfires, hurricanes) can be potentially catastrophic for drinking water supply and treatment; as a result, there is an increased interest in forest management for source water protection (SWP). While forests are managed for many purposes, they are not currently managed for protection of drinking water supplies. While the impacts of forest disturbance and management on water have been well studied,

加拿大58%以上的最大城市社区的饮用水来自森林流域。加拿大森林及其供应的沃茨的健康受到许多压力的威胁，包括气候变化可能造成的严重威胁，气候变化导致水质日益变化和恶化。这可能会使处理过程不堪重负，超出其设计能力，从而需要对处理过程进行可能成本高昂的改变，以确保提供安全的饮用水。全球森林的自然储存和过滤水的价值估计为4.1万亿美元，因此，森林水资源是加拿大和全球的战略优先事项。因此，在森林流域提供安全饮用水-安全-及其与自然和人类活动的关系是一个关键的优先事项。森林干扰（如野火、飓风）可能对饮用水供应和处理造成灾难性影响;因此，人们越来越关注森林管理以保护水源。虽然森林的管理有多种目的，但目前森林的管理并不是为了保护饮用水供应。虽然森林干扰和管理对水的影响已得到充分研究，
