While the number of people without electricity has dropped, experts predict that more than 600 million will still lack power in 2030. Nine out of 10 of them will live in sub-Saharan Africa.
This working paper describes water access challenges in cities of the global south that have been hitherto largely invisible in global indicators. In analyzing 15 cities, we found that piped utility water is the most affordable option, yet, on average, almost half of all households lack access, and most of those that do have access receive intermittent service. This paper highlights four key action areas for cities to improve water access: extending the formal piped water network, addressing context-specific causes of intermittent water service, pursuing diverse strategies to make water affordable, and supporting informal settlement upgrading.
This guide was developed for technical advisors to government officials, business people, investors, and others who need to draw on ecosystem assessments to inform decision-making. It assesses several types of ecosystem service modeling tool, discusses issues involved in modeling ecosystem services, and provides guidance on how to choose the right model to address a specific policy question. The guide outlined five steps to help decide which model to use in a particular decision-making context. It especially targets advisors and decision-makers in developing countries who are not experts in ecosystem service modeling and who have limited information and technical resources but must make decisions about natural resource management in relation to ecosystem services.
