Some coastal areas of Abun in Tambrauw Regency are quite vulnerable to extreme storms, floods, sea level rise, abrasion, landslides, and in some locations indicated drought. This is contained in a climate risk assessment compiled by WWF-ID with climatologists in 2022-2023. The study said the level of vulnerability varies from moderate to high because it is influenced by community capacity, type of climate risk, supporting infrastructure, government systems and capacity, data and information, and programs and policies in areas that have not targeted disaster programs holistically. For this reason, WWF-ID Papua Program together with Pioneer Partners through the VCA program voice action for climate change in an equitable manner has increased the capacity of the community to deal with climate change adaptively and prepare mitigation measures.
