 One of the Big Factors in Spreading Malaria is Climate Change
One of the biggest reasons behind malaria spread is climate change, but researchers have said that other factors such as migration and land-use changes are also likely to play a role.


The research aims to sort out contradictions that have emerged as scientists try to understand why malaria has been spreading into highland areas of East Africa, Indonesia, Afghanistan and elsewhere.

"We assessed ... conclusions from both sides and found that evidence for a role of climate in the dynamics is robust. However, we also argue that over-emphasizing a role for climate is misleading for setting a research agenda, even one which attempts to understand climate change impacts on emerging malaria patterns," said study authors Luis Fernando Chaves from Emory University and Constantianus Koenraadt of Wageningen University in the Netherlands.

Many studies have linked malaria spread to global warming, but that conclusion is far from unanimous.

Other studies have found no evidence of warming in highland regions, thus ruling out climate change as a driver for highland malaria.

Chaves and Koenraadt re-examined more than 70 of these studies and they found that the studies ruling out a role for climate change in highland malaria often use inappropriate statistical tools, casting doubt on their conclusions.
