在全球范围内,大多数生物多样性保护方案目前没有根据其成本和收益或原始投资的回报率进行评估。评估这类计划的成本效益具有挑战性,因为支出与养护成效之间的关系取决于许多生物和社会经济因素。在这里,我们评估通过苏格兰农村发展计划实施的一系列物种和栖息地保护计划的成本效益。我们使用基于专家知识的定量和定性数据相结合的方法来评估不同方案的有效性和成本效益,并了解结果中的差异。我们的发现突出表明,在资金可能实现最大保护效益的方面,缺乏地理目标,这可能是导致单位效益的高成本的原因之一。建议包括需要改进关于与目标密切相关的适当管理和监测方案的咨询意见。苏格兰境内的保护计划被用作研究的重点,但所采用的方法、得出的解释和确定的改进可以适用于任何区域、国家或国际生物多样性保护计划。成本和效益数据可能会受到高度不确定性的影响,因此任何成本效益估算都要受到一些警告。因此,不仅需要侧重于提高生物多样性养护方案的成本效益,而且还需要在数据可获得性和准确性以及改进对干预措施结果的监测方面,提高成本效益评估的稳健性。
Globally, most biodiversity conservation programmes are not currently evaluated in terms of their costs and benefits, or their rate of return on the original investment. Assessing the cost-effectiveness of such schemes is challenging as the relationship between spending and the effectiveness of conservation is dependent on many biological and socio-economic factors. Here, we evaluate the cost-effectiveness of a selection of species and habitat conservation schemes undertaken through the Scotland Rural Development Programme. We use a combination of quantitative and qualitative data, based on expert knowledge, to estimate effectiveness and cost-effectiveness of different schemes and understand variations in the results. Our findings highlight a lack of geographical targeting in terms of where the funding might achieve the most conservation benefit, which may be contributing to high costs per unit of effectiveness. Recommendations include the need for improved advice on appropriate management and monitoring programmes that are linked closely to objectives. Conservation schemes within Scotland were used as the focus of the study, but the approaches used, interpretations drawn and improvements identified could be applied to any regional, national or international biodiversity conservation programmes. Cost and effectiveness data can be subject to a high degree of uncertainty and hence any cost-effectiveness estimate is subject to a number of caveats. There is therefore a need to focus not only on improving the cost-effectiveness of biodiversity conservation programmes, but also to improve the robustness of cost-effectiveness assessments, in terms of data availability and accuracy and improved monitoring of the outcomes of interventions.
