Climate change affect the health of the population, not only through heat waves and waterborne diseases, but also as a result of the expansion of geographical areas conducive to the transmission of vector-borne diseases such as yellow fever, dengue and malaria. Species of mosquitoes, such as the group ‘Anopheles gambiae’, ‘A. funestus’, ‘A. darlingi’, ‘Culex quinquefasciatus’ and ‘Aedes aegypti’, are responsible for propagation of the majority of...

There is increasing evidence that climate change has a significant role in causing malaria epidemics. As climatic conditions change, the locations of suitable breeding habitats for the mosquitoes that transmit malaria and other diseases will change. This graphic shows the locations of malaria-free areas, malaria transmission areas and the areas in which malaria has largely been eliminated in Africa, as of 2002.

Multiple stresses make most of Africa highly vulnerable to environmental changes, and climate change is likely to increase this vulnerability. This graphic shows which of the regions of Africa (North Africa, West Africa, Central Africa, East Africa, Southern Africa and the Western Indian Ocean Islands) are most vulnerable to specific impacts of climate change. These impacts include desertification, sea level rise, reduced freshwater availability,...

Plasmodium vivax, with the Anopheles mosquito as a vector, is an organism causing malaria. The main climate factors that have bearing on the malarial transmission potential of the mosquito population are temperature and precipitation.

Climate change and altered weather patters would affect the range (both altitude and latitude), intensity, and seasonality of many major tropical vector-borne and other infectious diseases - such as malaria and dengue fever.

With climate conditions changing in the future, due to increased concentrations of carbon dioxide in the atmosphere, conditions for pests also change. The primary Malaria agent, the falciparum malaria parasite, will be able to spread into new areas, as displayed in this map, by 2050 using the Hadley CM2 high scenario. Other areas, not displayed in the map, will be uninhabitable by the parasite, and thus free of the pest.

The extent to which mortality is attributable to climate change remains a matter of intense debate. Data from the World Health Organization (WHO) for 2000 indicate that, in Latin America and the Caribbean, there were between 2 and 40 deaths per million inhabitants from floods, malaria and diarrhoea. In terms of regions, the most severe health effects have been in Africa, though significant effects are also being felt in Latin America and in certa...

Shows comparative trend between air temperature in Colombia and levels of malaria and dengue fever. When temperatures increase, especially in combination with more precipitation, vector borne diseases like malaria and dengue fever increase in frequency and distribution. In particular, areas where the minimum night temperatures increase provide the best conditions for the growth and spread of Anopheline spp. and Aedes aegypti mosquitoes. (McCarth...

The construction of large dams - defined as those with walls at least 15 metres high - has increased significantly over the past 50 years. The average height of new dams, estimated at 30-34 m from 1940-1990, increased to about 45 m in the 1990s, due largely to construction trends in Asia. The average area and volume of freshwater reservoirs have also steadily increased, rising to about 50 km2 between 1945 and1970, declining through the 1980s to 1...
