Our recent research examines the role of nature-based solutions (NbS) in addressing climate vulnerability in Bangladesh and rural Global South in general, and on ensuring NbS support both biodiversity and climate change adaptation.
We have summarised the key findings from these studies for policymakers in three briefings.
This briefing ‘Tackling climate change with nature-based solutions in Bangladesh’ summarises a review by Smith et al. (in press) that found robust evidence that NbS can provide resilient and effective protection from climate risks while also supporting sustainable development and enhancing biodiversity.
The briefing includes recommendations for policymakers that focus on integrating support for NbS into government policy, focusing on four key success factors:
Understanding the benefits of NbS can help to make the case for protecting Bangladesh’s remaining high-value natural assets, including the Sundarbans mangroves and Chittagong hill forests, as well as implementing more sustainable agricultural practices such as agroecology and agroforestry in the farmed landscape.

This briefing ‘Reducing people’s vulnerability to climate change in the rural Global South using Nature-based Solutions’ synthesizes the findings of a recently published assessment of the effectiveness of nature-based interventions at reducing social and ecological vulnerability through different pathways, with findings that suggest that NbS (such as ecosystem-based adaptation), can help reduce people’s vulnerability to climate change impacts across a diversity of social and environmental contexts.
The briefing includes four recommendations for policymakers:
Increasing insight into whether and how NbS reduce vulnerability to climate change in the Global South is key, given that this region is home to the majority of the world’s most climate-vulnerable people.

Biodiversity & Climate Change Adaptation
The study reviewed the effects of nature-based interventions for climate change adaptation on different metrics of ecosystem health (such as the diversity of species, their population sizes, or soil and water quality). Most interventions with positive outcomes for climate change adaptation also reported measurable benefits for ecosystem health. However there was also evidence of some trade-offs between outcomes for climate and biodiversity, mainly resulting from interventions involving forest management and creation of novel ecosystems that are not designed according to the ecological context, or with biodiversity in mind.
The briefing, ‘Ensuring Nature-based Solutions support both biodiversity and climate change adaptation’, includes recommendations for policymakers:
Research, practice and policy communities need to work together, and with local communities, to improve the design, monitoring and management of NbS so that they deliver clear benefits for biodiversity and ecosystem health alongside climate goals.
