Abstract

ABSTRACT The paper analyses sources of delay in developing environmental interventions to address overallocation of groundwater and water quality degradation for Te Waihora/Lake Ellesmere, a coastal lake in the Canterbury Region of New Zealand. The analysis highlighted the length of time required to collect the science to understand an issue and to formulate and implement policy responses. It also identified delays due to scientific uncertainty, scientific controversies, disregarding science, decision processes, and the response time of the natural system. The absence of clear policy approaches and environmental outcomes in order to implement environmental legislation was a significant source of delay. Delays in implementing environmental interventions led to loss of natural capital with groundwater overallocation reducing flows in groundwater-fed streams and freshwater inflows to the lake, and land use intensification degrading groundwater, groundwater-fed streams, and lake water quality. The extent of development beyond sustainable limits during these delays may have permanently compromised the ability to implement comprehensive environmental interventions.
科学和政策的滞后导致自然资本的损失:以怀霍拉湖/埃尔斯米尔湖为例
摘要:本文分析了新西兰坎特伯雷地区沿海湖泊怀霍拉/埃尔斯米尔湖(Te Waihora/Lake Ellesmere)为解决地下水过度分配和水质退化问题而采取环境干预措施的延误原因。该分析强调了收集科学以理解一个问题以及制定和实施政策应对所需的时间长度。它还确定了由于科学不确定性、科学争议、无视科学、决策过程和自然系统的响应时间而导致的延迟。执行环境立法缺乏明确的政策办法和环境成果是造成拖延的一个重要原因。实施环境干预措施的延误导致自然资本的损失,地下水的过度分配减少了地下水溪流的流量和流入湖泊的淡水,土地利用集约化使地下水、地下水溪流和湖泊水质退化。在这些延误期间,超出可持续限度的发展程度可能会永久损害执行全面环境干预措施的能力。

期刊介绍: The Australasian Journal of Water Resources ( AJWR) is a multi-disciplinary regional journal dedicated to scholarship, professional practice and discussion on water resources planning, management and policy. Its primary geographic focus is on Australia, New Zealand and the Pacific Islands. Papers from outside this region will also be welcomed if they contribute to an understanding of water resources issues in the region. Such contributions could be due to innovations applicable to the Australasian water community, or where clear linkages between studies in other parts of the world are linked to important issues or water planning, management, development and policy challenges in Australasia. These could include papers on global issues where Australasian impacts are clearly identified.
