Use of water by wildlife is not explicitly considered in any part of the System of Environmental-Economic Accounting (SEEA). However, wildlife uses water and in some cases this may be in conflict with other water uses (e.g. irrigation). To examine the magnitude of this problem and the conceptual and practical challenges of including wildlife water use in the SEEA, estimates of water use for 31 mammals in Botswana were developed using readily available data on their abundance and coefficients of water use. Three recording options were considered for the physical supply and use tables: (1) water use by wildlife shown in a new column entitled “Wildlife”; (2) shown as a use by industry under “Operation of nature reserves” and; (3) the preferred option, shown as a split between the first two options, reflecting the location of wildlife inside or outside national parks. The key conceptual issue for recording is the delineation of the production boundary, determined in this case by the extent to which wildlife is deemed managed and hence akin to a cultivated resource in the SEEA. Despite some data limitations, wildlife water use in Botswana was significant, with 21 species accounting for 19,345 ML in 2012–13, equivalent to 10% of the previously estimated water consumption in that year. Water account producers now have clear options for including wildlife, providing water planners and wildlife managers with improved information to help balance competing demands for water that may occur at particular times and places.

野生动物用水的概念和实践问题以及博茨瓦纳的案例研究

在环境经济核算系统(SEEA)的任何部分中都没有明确考虑野生动植物使用水的情况。但是,野生动植物使用水,在某些情况下,这可能与其他用水(例如灌溉)冲突。为了研究这个问题的严重性以及在SEEA中纳入野生动植物用水的概念和实际挑战,利用现有的丰富程度和用水系数的现有数据,对博茨瓦纳31种哺乳动物的用水进行了估算。为实物供应和使用表考虑了三个记录选项:(1)在标题为“野生生物”的新列中显示的野生生物用水;(2)在“自然保护区的运营”项下显示为行业用途;以及 (3)首选选项,显示为前两个选项的拆分,反映国家公园内外野生生物的位置。记录的关键概念问题是生产边界的划界,在这种情况下,确定边界取决于野生动植物被视为受到管理的程度,因此类似于SEEA中的耕种资源。尽管有一些数据限制,博茨瓦纳的野生动植物用水量还是很大的,2012-13年有21个物种占19,345 ML,相当于该年先前估计用水量的10%。水资源账户生产者现在拥有包括野生生物在内的明确选择,可以为水规划人员和野生动植物管理者提供改进的信息,以帮助平衡在特定时间和地点可能发生的对水竞争的需求。在这种情况下,取决于认为野生动植物受到管理的程度,因此类似于SEEA中的耕种资源。尽管有一些数据限制,博茨瓦纳的野生动植物用水量还是很大的,2012-13年有21个物种占19,345 ML,相当于该年先前估计用水量的10%。现在,水账户生产者可以选择包括野生生物在内的明确选择,为水规划者和野生动物管理者提供改进的信息,以帮助平衡在特定时间和地点可能出现的对水的竞争需求。在这种情况下,取决于认为野生动植物受到管理的程度,因此类似于SEEA中的耕种资源。尽管有一些数据限制,博茨瓦纳的野生动植物用水量还是很大的,2012-13年有21种物种占19345 ML,相当于该年先前估计用水量的10%。水资源账户生产者现在拥有包括野生生物在内的明确选择,可以为水规划人员和野生动植物管理者提供改进的信息,以帮助平衡在特定时间和地点可能发生的对水竞争的需求。相当于该年先前估计用水量的10%。水资源账户生产者现在有明确的选择来包括野生生物,为水规划者和野生动物管理者提供了改进的信息,以帮助平衡在特定时间和地点可能发生的对水竞争的需求。相当于该年先前估计用水量的10%。水资源账户生产者现在有明确的选择来包括野生生物,为水规划者和野生动物管理者提供了改进的信息,以帮助平衡在特定时间和地点可能发生的对水竞争的需求。
