Sri Lanka faces significant climate change risks, particularly in the context of public health. Recognizing the potential dual benefits of raising awareness in vulnerable communities about climate-related health risks, the objective of this project is to contribute to improving climate resilience among vulnerable Sri Lankan communities, by ensuring that the Government of Sri Lanka responds effectively to the impacts of climate change through efficient community engagement (Outcome 1). To achieve this outcome, the project will first conduct an in-depth assessment and develop a climate health risk communication strategy, including a national action plan that captures the needs of vulnerable groups (Output 1.1). The project will then capacitate public health officers and other relevant officials, to ensure that they have skills and tools to effectively communicate climate adaptation messages through climate health risk education (Output 1.2). Finally, the training will be cascaded through community leaders to ensure that at-risk communities can engage with and demonstrate the impact of health risk communication in their respective communities (Output 1.3). Through this community-driven approach, vulnerable populations will gain knowledge, adopt practices for their well-being, and effectively manage resources, reducing disease risks. The project aims to improve knowledge and behaviour, fostering resilience to climate-induced health impacts and alleviating the burden on the health system.
