Nature-based solutions involve working with nature to promote human well-being and to support climate mitigation and adaptation actions to reduce climate risk. However, there is some concern amongst scholars in the Global South regarding the appropriateness of some of these solutions in local contexts. This is especially applicable in Africa, where many peoples’ livelihoods are heavily dependent on their landscapes and the multiple ecosystem services derived from these landscapes. These challenges are compounded by the fact that there is very little research on the longevity of nature-based solutions under a constantly changing climate.
The overall objective of this project is to support decision-making, planning, and implementation processes across 11 countries in southern Africa to ensure that nature-based solution initiatives at local and national levels are more equitable and sustainable. It focuses on southern African water towers, which are mountains and plateaus critical to the water supply. Just under half of these towers have already been earmarked for nature-based solutions, particularly for global benefits such as carbon sinks.
The project will identify the biophysical limits of the nature-based solutions proposed for the different water towers under future climate change and model the global carbon versus regional and local water trade-offs involved. It will unpack the economic, social, and political processes and trade-offs that shape which interventions are adopted and who benefits (with a focus on gender dimensions). It will explore the constraints to implementation, particularly in terms of ensuring fair distribution of global versus local benefits and avoiding local negative outcomes. It will also engage with the policy and practice communities to consider the findings and examine what is needed to support more equitable and sustainable implementation of nature-based solutions in southern Africa’s water towers.

Nature-based solutions (NbS) – ecosystem protection, restoration, sustainable management, and creation – are increasingly being promoted to support human well-being and ecosystem health, particularly in the context of a changing climate. As such, NbS are gaining popularity globally in international policy and programmes resulting in an increase in multilateral funding from the Global North for NbS projects in developing countries. However, concerns have arisen around how suitable these interventions are in local contexts where local communities are heavily reliant on natural resources given the potential for social, economic, and environmental trade-offs. This research aimed to address these concerns by exploring: i) whether and how social equity has been considered in NbS project design, particularly in relation to vulnerable groups; and ii) whether project sustainability (in terms of longevity and more broadly in terms of sustainable development) has been linked to social equity. The research focused on Southern African NbS projects that are of relevance to areas important to water supply (known as Water Towers).
