Abstract

Nature-based solutions have gained popularity as an approach to reduce the impacts of climate and environmental change, providing multi-fold and multi-sectoral benefits especially in cities. Yet there has been growing concern about their utility for cities of the Global South, a concern fuel led by the paucity of studies, including scientific peer reviewed and gray literature. In this paper, we contribute to this knowledge gap, based on an analysis of 120 case studies of NBS in Global South cities, documented in two databases (Urban Natural Atlas and Oppla). These cases fall largely under categories of blue and green infrastructure, with a few cases also focusing on grey infrastructure (in buildings or campuses). While most cases are in Asia, several have also been documented in Africa and Central/South America. Two-third of documented NBS cases are aligned towards either national, or lower-level (regional and local) policies indicating the importance of policy mechanisms for driving their implementation. Institutional arrangements are usually non-government, government or collaborative arrangements, with the goal of climate resilience, biodiversity support and ecosystem restoration—along with social goals of creating public spaces. However, when private players take on the mandate for NBS, they focus primarily on grey infrastructure (in buildings and campuses), primarily meant for private or employee benefits,and not for the public. In cases where public engagement is a stated priority, we find tokenistic approaches deployed, primarily seeking engagement through information dissemination and consultation predominate. Despite the stated importance for participation and engagement, only a few cases focused on empowerment and co-creation of NBS with local communities. We suggest that there is a greater need for documentation regarding the modes of participation especially on roles and levels of actors involved, to enrich our understanding of the impact of NBS on values of justice and equity in the cities of the global South.
