To achieve inclusive and sustainable urban development, the introduction of water related Nature Based Solutions (NBS) have proven to be eff ective in specific urban contexts. Different sources point out their contribution to various SDG’s in Europe, Australia and the United States, all of which are regions with high GDP levels with strong institutional contexts. However, in regions that are underdeveloped, have weak institutional contexts, high social and economic inequality and are situated in more vulnerable or extreme landscapes, the so called ‘vulnerable geographies’, the experience with Nature Based Solutions is less extensive (PBL, 2018). This report presents the results of a literature review that aims at providing a first (broad) exploration of NBS in contexts outside the regions mentioned above.@en
