The Protocol on Water and Health provides a framework for countries to attain an adequate supply of safe drinking water and adequate sanitation for everyone and effectively protect water used as a source of drinking water. Article 6 and 7 of the Protocol require Parties to set targets to improve the water, sanitation and health situation and collect and evaluate data and information on their progress towards the achievement of the targets. In 2010, in order to assist Parties in addressing challenges connected with setting targets and reviewing and assessing progress, Guidelines on the Setting of Targets, Evaluation of Progress and Reporting were published. While applying the Guidelines, countries have accumulated ample experiences including stories and key elements that made their process successful as well as areas where things could have been done differently. Recognizing the usefulness of this collective experience and the benefits from learning from the good practices and replicating them, the Task Force on Target Setting and Reporting decided to prepare the present publication. The objective of the Collection of Good Practices and Lessons Learned on Target Setting and Reporting is to provide concrete advice to countries that are or will embark in the process of setting, revising or implementing their targets, as well as for their reporting on the progress achieved in accordance with the Protocol. This publication is a compilation of success stories, challenges and diverse approaches applied by Parties and other States working in the framework of the Protocol. It aims at complementing the Guidelines on the Setting of Targets, Evaluation of Progress and Reporting by focusing on how they have been implemented in practice. It follows the logical framework laid out in the Guidelines for the process of setting targets and reporting covering each step of the process.
