A recent study published in the journal Lancet Planetary Health warns that many countries will not be prepared for an increase in snakebites due to venomous snakes migrating to new areas as a result of climate change. The study used models to predict the potential geographic distribution of 209 venomous snake species by 2070, taking into account climate conditions. While some species will experience range contractions, others, such as the West African gaboon viper, are projected to see their range increase significantly.
Habitat loss due to land conversion for agriculture and livestock is a major factor contributing to the displacement of snakes. Researchers highlight Nepal, Niger, Namibia, China, and Myanmar as countries that will be most affected by the influx of venomous snake species from neighboring regions. Low-income countries in South Asia, Southeast Asia, and parts of Africa are expected to see a rise in snakebite cases.
Snakebite envenomation is classified as the top neglected tropical disease by the World Health Organization (WHO), which estimates that millions of people are bitten by venomous snakes each year, resulting in thousands of deaths and cases of permanent disability. The study emphasizes the importance of understanding how climate change impacts snake distribution to better prepare for the potential increase in snakebite incidents.
The researchers stress the need for proactive measures to address the risks posed by venomous snakes moving into new territories. With proper awareness and preparation, countries can better mitigate the impact of snakebites on public health.
