Goal: Dengue and malaria are considered the most health burden under changing climate in Vietnam and Philippines, where impacts of climate change appear severely due to more frequent flooding and typhoons. The objective of the project is to improve the knowledge of the above vector-borne diseases and their vulnerability to climate variability for rural population in both countries by using advanced geospatial technology. The study will cover a period of 20 years over disease exposure areas determined by pattern matching approach. The project activities are comprised of collecting data and field survey to develop a geospatial database; data analysis; and mapping vulnerability of health to climate change. Expected outputs of the project include the database of climate change related diseases, temporal trends and distribution patterns of disease incidence and its relations to variability of climate and socio-economic conditions, and vulnerability maps of mosquito-borne diseases under climate change. The project results will support adaption planning and decision making in health sector via providing disease information and vulnerability.
