摘要

摘要本研究估算了地下水过度开采和海水入侵对农田造成的经济损失。从水文、农艺和经济三个方面着手解决沿海地下水盐碱化问题。考虑到持续和适应性浇水技术,对竞争性使用与管制管理制度进行了经济分析。我们专注于农民对水作为农业投入的看法,并评估了30年期间的贴现净现值。这项研究的最终目标是通过展示过度开发的经济影响(从农民的角度来看)来提高农民和政策制定者的意识。我们对普利亚地区(意大利南部)的研究结果表明,盐度长期影响的缓慢性和农民适应灌溉概况的能力表明,政策干预的视角应该拓宽。为了有效管理这一共同资源,决策者应根据经济分析采取更全面的办法。

Economic analysis of the long-term effects of groundwater salinity: bringing the farmer’s perspectives into policy
Abstract This research estimates the economic losses at the farm level caused by groundwater over-exploitation and by seawater intrusion. The problem of coastal groundwater salinity was tackled by considering its hydrological, agronomic and economic aspects. Economic analysis for competitive use vs. regulated management regimes was carried out, considering constant and adaptive watering techniques. We concentrate on the farmers’ perspective of water as an input in agriculture, and assess discounted net present value over a period of 30 years. The ultimate goal of this research is to raise the awareness of farmers and policy makers by demonstrating the economic impacts (from the farmer’s point of view) of over-exploitation. Our findings for Apulia Region (Southern Italy) indicate that the slowness of the long-term effect of salinity and the ability of farmers to adapt irrigation profiles suggest broadening the perspective of policy intervention. For an effective management of this common resource, policy makers should follow a more comprehensive approach based on economic analysis.

期刊介绍: Journal of Integrative Environmental Sciences (JIES) provides a stimulating, informative and critical forum for intellectual debate on significant environmental issues. It brings together perspectives from a wide range of disciplines and methodologies in both the social and natural sciences in an effort to develop integrative knowledge about the processes responsible for environmental change. The Journal is especially concerned with the relationships between science, society and policy and one of its key aims is to advance understanding of the theory and practice of sustainable development.
