Abstract

Nature-based solutions (NbS) leverage the power of ecosystems and biodiversity to address societal challenges. NbS for addressing water security challenges in cities are widely recognized for accelerating sustainability and delivering multiple co-benefits. However, peer-reviewed studies and implementation guidance have primarily focused on the Global North, necessitating adaptation for the Global South. While NbS could provide environmental and socio-economic benefits, the specific adaptations required for planning, designing, and implementing in the context of the Global South remain unclear. During the 6th Symposium on Urbanization and Stream Ecology (SUSE 6) held in Brisbane, Australia, in May 2023, a group of interdisciplinary experts discussed these challenges. This was followed by in-depth discussions with additional experts spanning various sectors across the Global South and a comprehensive literature review. This paper presents the outcomes of these efforts specifically focused on three objectives: understanding the NbS planning context in the Global South, identifying unique challenges for implementing NbS in these regions, and identifying “bright spots” as learning opportunities for implementation.
