Global warming can cause various types of disasters, one of which is drought.
According to the Intergovernmental Panel on Climate Change (IPCC), the population threatened by drought due to global warming could reach around 1 billion people.
The IPCC projects that if the average global temperature rises by 1.5 degrees Celsius (°C) compared to the pre-industrial era (1850-1900), the population vulnerable to drought will reach 951 million people.
Then, if the average global temperature rises by 2 °C, the threat of drought will extend to 1.15 billion people.
The population vulnerable to drought could also reach 1.28 billion people if the global temperature increase reaches 3 °C above the pre-industrial era.
According to the IPCC, such droughts could reduce or eliminate water sources, trigger environmental degradation, reduce agricultural production, and create socio-economic problems.
"The combination of climate variability, anthropogenic climate change, and desertification will drive poverty, food insecurity, and increased disease," said the IPCC in its *Special Report on Climate Change and Land* (2019).
"Women will be more affected than men, especially in regions with high dependence on the agricultural sector," it continued.
To prevent these risks, the IPCC states that the global community needs to ensure that the increase in global temperature does not exceed 1.5 °C, including by massively reducing greenhouse gas emissions.
