28. 《约翰内斯堡执行计划》致力于“通过在所有各级采取行动，到 2005 年时制定水资源综合管理计划和用水效率计划，并向发展中国家提供支持”。在约翰内斯堡举行世界首脑会议后三年内制定此类计划的目标过于雄心勃勃；然而，经过各方的共同努力，特别是联合国开发计划署(开发署)和联合国水机制的合作伙伴——全球水事伙伴关系的努力，在“十年”期间，在实现这一目标方面取得了重大进展。根据关于采用综合性办法开发、管理和利用水资源的 2012 年状况报告，“80%的国家已经着手进行改革，根据在《21 世纪议程》中阐明、由《约翰内斯堡执行计划》确认的综合性办法，为水资源管理创造更加有利的环境”。13
28. The Johannesburg Plan of Implementation committed to “develop integrated water resources management and water efficiency plans by 2005, with support to developing countries, through actions at all levels”. The goal of developing such plans within three years of the holding of the World Summit in Johannesburg had been overly ambitious; nonetheless, through concerted efforts, especially by the United Nations Development Programme (UNDP) and the UN-Water Global Water Partnership (GWP), substantial progress was made during the Decade towards achieving this target. According to the 2012 status report on the application of integrated approaches to the development, management and use of water resources, “80 per cent of countries have embarked on reforms to improve the enabling environment for water resources management based on the application of integrated approaches as stated in Agenda 21 and affirmed in the Johannesburg Plan of Implementation”.
