Climate change refers to any change in climate over time, whether due to natural variability or as a result of human activity. Climate change affects public health directly or indirectly. One of the noticeable effects of climate change is on diarrhoeal diseases. Diarrhea accounted for 3.6% of the global disease burden in 2010, with much of this burden concentrated in poor regions. Global climate change is expected to increase the risk of diarrhoeal diseases, a leading cause of childhood mortality. However, there is considerable uncertainty about the magnitude of these effects especially in developing countries like Nepal in the absence of such research studies. A study conducted in Peru shows that ambient temperature rise of 1◦C could lead to 8% increase in the incidence of diarrhea. Similarly, another study carried out in Pacific Island shows that rise of 1◦C could result in 3% increase in the incidence of diarrhea. Despite huge investment by Nepal Government on water, sanitation, and hygiene to reduce the burden of diarrhoeal diseases, the burden of diarrheal diseases is still high and frequent epidemics of diarrhea and cholera are reported every year. In some districts, the incidence of diarrhea is on increasing trend. In this study, we aim to estimate attribution of climatic factors on the incidence of diarrheal diseases in Nepal.
The main purpose of this study was to assess effects of climatic factors on the incidence of diarrheal diseases in Nepal.
Analytical report on the assessment of climatic factors on the incidence of diarrheal diseases in Nepal is available.
