The Impact of Deforestation On Malaria

Deforestation in Brazil has led to an increase in malaria cases, according to a new study in Nature. The study found that areas affected by one kilometre square of deforestation produced 27 new malaria cases. Moreover, their results emphasise not only that deforestation promotes malaria incidence, but also that it directly or indirectly results in a low Human Development Index (HDI), and favours environmental conditions that promote malaria vector conception. As shown in the figures above, the impact of deforestation on malaria cases is bigger than it is with forest degradation and impacted forests. Simple linear regression analyses showed that each km² of deforestation corresponded to an increase of 27 new malaria cases, whereas each km² of impacted forest corresponded to an increase of 16 new cases.
