Abstract

Water has important economic values, mainly in the agricultural sector. Beside enhancing agricultural output and crop diversification, irrigation generates positive externalities which have been little emphasized by the literature. The purpose of this review is to investigate the direct, indirect and potentialbenefits of water use in agriculture by taking an additional step towards the identification and economic evaluation of the observed positive, social, environmental and ecological effects of irrigation. Five categories of contributions are examined: irrigation returns flows for groundwater recharge; biodiversityand wildlife habitat; landscape aesthetic and cultural values; nutrient recycling and retention; and improved health, nutritionand living conditions. Knowing the economic value of such positive externalities would help to get the right policy incentives for better water use and increased water savings in a context of growing water scarcity.

关于灌溉农业的正外部性及其政策含义:综述

水具有重要的经济价值，主要在农业部门。除了提高农业产量和作物多样化外，灌溉还产生了文献中很少强调的正外部性。本综述的目的是通过进一步确定和经济评估所观察到的灌溉的积极、社会、环境和生态效应，调查农业用水的直接、间接和潜在效益。研究了五类贡献:灌溉回报地下水补给流量;生物多样性和野生动物栖息地;景观美学和文化价值;营养物质的循环和保留;改善健康、营养和生活条件。了解这种积极外部性的经济价值将有助于在日益缺水的情况下获得正确的政策激励，以更好地利用水和增加节约用水。

期刊介绍： Economia agro-alimentare/Food Economy is a triannual peer-reviewed scientific journal published by Franco Angeli Edizioni on behalf of the Italian Society of Agri-food Economics (SIEA), founded in 1996 by the then President of SIEA Fausto Cantarelli. It offers an international forum for the discussion and analysis of mono and interdisciplinary socio-economic, political, legal and technical issues, related to agricultural and food systems. It welcomes submissions of original papers focusing on agriculture, food, natural resources, safety, nutrition and health, including all processes and infrastructure involved in providing food to populations; as well as the processes, inputs and outputs involved in consumption and disposal of food and food-related items. Analyses also include social, political, economic and environmental contexts and human resource challenges. Submissions should be addressed to an international audience of researchers, practitioners, and policy makers, and they may consider local, national, or global scales.
