23Impacts
24food insecurity and exacerbated malnutrition in
Tanzania
2519of Tanzanian health spending IS on malaria
Due to escalating warming, Tanzania is
experiencing outbreaks of malaria in highland
areas where there is little experience with the
disease. Health authorities are combining climate
observations with medical research to predict
highland malaria outbreaks
26Afternoon winds are consistently stronger than
morning winds which translate into enhanced
production of damaging erosion capability
including tidal effects especially during the
period between September and December.
