WHODjiboutiDeadline: Aug 31The Philippines is among the countries most vulnerable to the impacts of climate change, facing increasing risks from extreme heat, typhoons, flooding, sea-level rise, and other climate-related hazards. These hazards have significant implications for public health, including increased injuries and deaths, climate-sensitive diseases, food and water insecurity, and disruptions to essential health services. Strengthening the resilience of communities and health systems is therefore critical to protecting health and reducing climate-related vulnerabilities. Pursuant to Republic Act No. 9729 (Climate Change Act of 2009) and Republic Act No. 10121 (Philippine Disaster Risk Reduction and Management Act of 2010), the Department of Health (DOH) is advancing the development of a Health National Adaptation Plan (HNAP) to integrate climate change adaptation into health sector planning. A comprehensive Climate and Health Vulnerability and Adaptation (V&A) Assessment is needed to identify priority climate-sensitive health risks, vulnerable populations, geographic hotspots, and health system gaps. The assessment will provide the evidence base for targeted adaptation actions, investment planning, and the development of climate-resilient health systems at national and subnational levels. In line with this, WHO is seeking an institutional contractual partner to provide technical assistance on the Conduct of Climate Change and Health Vulnerability and Adaptation (V&A) Assessment in Support of the National Adaptation Plan (HNAP), Philippines.
