Approximately 1 billion people currently live in informal settlements, primarily in urban areas in low- and middle-income countries. Informal settlements are defined by poor-quality houses or shacks built outside formal laws and regulations. Most informal settlements lack piped water or adequate provision for sanitation, drainage, and public services. Many are on dangerous sites because their inhabitants have a higher chance of avoiding eviction. This paper considers how to build resilience to the impacts of climate change in informal settlements.
Despite global policy commitments to preserve Earth's marine biodiversity, many species are in a state of decline. Using data on 22,885 marine species, we identify 8.5 million km2 of priority areas that complement existing areas of conservation and biodiversity importance. New conservation priorities are found in over half (56%) of all coastal nations, including key priority regions in the northwest Pacific Ocean and Atlantic Ocean.
