Bulletins on emerging environmental issues inform policy and decision makers, as well as the decision making organs of governments and the general public. They are peer reviewed by accredited scientists and experts. They are based on cutting-edge scientific studies. They are also a good opportunity to promote, update and re-use as much as possible of DEWA’s Regional Centres material such as articles, maps, graphs and analyses. These case studies can be a powerful tool to inform and have a large benefit for public and policy-makers’ awareness, within the UN system and on a wider scale. The stories could serve various UNEP processes, as well as provide insight and directions for new projects and research.
