Cambodia is amongst the most vulnerable countries in South-East Asia to climate change and its health impacts, with seven of its provinces in the top 50 most vulnerable regions (Yusuf A 2010).
Vector-borne diseases (VBDs) such as dengue fever and malaria are particularly susceptible to climate change, due to climatic influences on the range, survival and behaviour of their insect vectors (mosquitoes) which transmit these pathogens to humans and influence on the replication of the virus (for dengue) and parasite (for malaria). In general, transmission dynamics favour warmer and wetter environments, such as the environment in many areas of Cambodia. Threats from other VBDs beyond dengue and malaria are also a potential, such as Chikungunya and Zika virus. Recent reports of the presence of these diseases in regional countries and the fact that they are also transmitted by the same Aedes mosquitoes that transmits dengue, further increase the threat they pose.
There are also adverse effects and impacts of climate change on water quality (safety), water quantity (availability) and water-related diseases (WRDs). Cambodia already suffers from a significant burden of WRDs.
- Improved understanding of health professionals regarding climate change and health risks – particularly those posed by vector-borne diseases, water-related diseases, and hydro-meteorological disasters, such as droughts and floods – and increased capacity to prevent, diagnose and manage these priority climate-sensitive diseases;
- Strengthened national institutional capacity to conduct integrated, climate-based, community, vector and epidemiological surveillance of climate-sensitive diseases;
- Enhanced capacity of the health sector reduce disaster risk, build resilience and manage the health impacts of disasters; and
- Increased community and stakeholder awareness of the health risks posed by climate change on extreme weather events, vector-borne and water-related diseases, and improved understanding and use of health-protective behaviors.
- To improve health care infrastructure and capacity of health personnel to cope with vector-borne and water-borne diseases in the context of climate change;
- To enhance emergency preparedness and response to cope with extreme weather and climate change-related disasters;
- To improve knowledge and research capacity on health impacts and vulnerability to climate change as an information base for mainstreaming climate change in the health strategic planning of the Ministry of Health and other sector plans;
- To increase resilience capacity of the population in combating vector-borne and water borne diseases arising from climate change;
- To reduce impacts of extreme weathers and disasters through better emergency preparedness and response plans;
- To build knowledge of the population and health personnel to cope with climate change impacts.
- Water-born diseases and disasters: Kandal, Siem Reap, Banteay Meanchey, Mondul Kiri, Rattanak Kiri, Battambang, Kampong Thom, Kampong Cham, Tboung Kmum, Kratie, Pursat, Stung Treng, Takeo, Prey Veng, Koh Kong, Preah Vihear, Sihanouk, Kampot, Kampong Speu province and Phnom Penh municipality.
- Vector-born diseases: Preah Vihear, Koh Kong, Rattanakiri, Mondul Kiri, Siem Reap, Banteay Meanchey, Tboung Kmum and Kandal Province.
- The population vulnerable to VBD transmission and WRDs will benefit from strengthening and expansion of existing VBD & WRD prevention and treatment services.
- Community awareness activities informing at risk populations of climate change risks and appropriate behavior to protect from VBDs and WRDs.
- Population vulnerable to extreme weather events in disaster prone provinces will benefit from preparedness interventions and awareness raising of disaster risks to health.
- Government ministerial staff and provincial staff will undergo appropriate training to enhance skills for improving climate change and health adaptation planning and response. Ministries will also participate in and gain from interactions in TWGs and associated meetings.
- Reduced risk of VBD transmission, burden of WRDs and health impacts of extreme weather events, along with improved case management of VBDs and WRDs resulting in lower case fatality rate in selected project sites.
- Improved understanding of associations between climate change and VBDs, WRDs and extreme weather events impacting health, as well as determinants of health and the utility of integrated early warning systems;
- National policy dialogue to include health as an important component of climate change adaptation, with VBDs, WRDs and extreme weather events impacting health as an example of a tangible adaptation strategy.
