越来越多的小农利用自己的资源从事灌溉。他们购买或租用灌溉设备，从附近的水源取水，不依赖公共机构或用水者协会，也不受其干扰。在南亚，农业用水管理的个性化已经持续了几十年，现在大多数灌溉都是从私人拥有的威尔斯井进行的。最近，撒哈拉以南非洲也出现了小型私人灌溉。它是由农民驱动的，响应了小农的真正需求，并对扶贫和农村发展具有巨大潜力。在许多国家，私人管理和拥有的灌溉面积大于公共灌溉计划的面积。然而，灌溉的个性化及其自发、不受控制的蔓延对公平获得水资源和可持续管理水资源构成挑战。灌溉投资和研究工作主要集中在表现不佳的公共灌溉部门，忽视了小型私人灌溉。本期特刊以撒哈拉以南非洲的五个国家和印度的两个邦为例，描述和分析了这一蓬勃发展但被忽视的行业。作者探讨了在不损害现有水资源可持续性的情况下，提高小型私人灌溉潜力的方法。(C)2013爱思唯尔有限公司版权所有。
An increasing number of smallholder farmers engage in irrigation using their own resources. They buy or rent irrigation equipment and draw water from nearby sources without depending on or without interference from public agencies or water user associations. The individualization of Agricultural Water Management has been ongoing for several decades in South Asia where most irrigation now takes place from privately owned wells. Recently, small private irrigation is emerging also in sub Saharan Africa. It is farmer-driven, responds to a genuine demand from smallholders and has substantial potential for poverty alleviation and rural development. In many countries the area under privately managed and owned irrigation is larger than under public irrigation schemes. However, the individualization of irrigation and its spontaneous, unchecked spread pose challenges to equitable access to and sustainable management of water resources. Irrigation investments and research efforts have largely focused on the underperforming public irrigation sector, ignoring small private irrigation. This special issue describes and analyzes this thriving but overlooked sector, drawing from examples from five countries in sub-Saharan Africa and two states in India. The authors explore ways to enhance the potential of small private irrigation for all, without jeopardizing the sustainability of the available water resources. (C) 2013 Elsevier B.V.
