Extreme Weather Linked to Increased Gender-Based Violence

Countries severely impacted by climate change may experience higher rates of violence against women. Published in PLOS Climate, the research investigated how climate shocks—such as storms, landslides, and floods—could be associated with increased intimate partner violence in the two years following such events. ()

The researchers gathered data on intimate partner violence from 363 surveys conducted in 156 countries between 1993 and 2019, focusing on women who currently had a partner. Intimate partner violence was defined as any physical and/or sexual violence in the past year.

Health Effects of Global Warming
Greenhouse effect causes excessive heat to build up in the earth’s atmosphere causing global warming and affects the environment and health.

Climate Shocks, Economic Status, and Intimate Partner Violence

The team also gathered data on climate shocks from 1920 to 2022 in 190 countries. They then analysed the relationship between climate shocks and intimate partner violence, while also considering the country’s economic status.

They found that there was a significant link between intimate partner violence and certain climate shocks (including storms, landslides and floods). Meanwhile, other types of climate shocks (such as earthquakes and wildfires) didn’t show a clear connection to intimate partner violence.

Lead author, Professor Jenevieve Mannell (UCL Institute for Global Health), said: “Existing evidence has found that when a woman experiences a climate-related event, she is more likely to experience violence in some countries and for some types of violence, but not others.

Link Between Lung Cancer Progression and Neighborhood Violence
Living in high-violence neighborhoods may accelerate lung cancer, as stress responses vary between cancerous and healthy tissues in affected individuals.

“We set out to explore what was happening at a national level to help inform international climate change policy.”

The researchers were unable to assess why different climate shocks have more of an impact on intimate partner violence. However, they believe that different shocks may take different amounts of time to have an effect on violence and this may not have been captured in the two-year window studied, due to data availability.

Partner Violence and Child Abuse Raise Type 2 Diabetes Risk
The different types of violence elevate the susceptibility to stress-related trauma disorders, which contribute to the onset of adult diabetes.

As a result, they are calling for more regular data collection by countries on measures of violence against women.

Professor Mannell added: “A small body of evidence shows that heat and humidity increases aggressive behaviours, including violence. Climate-related disasters increase stress and food insecurity in families in ways that can lead to increases in violence. They also reduce the social services often available for dealing with partner violence, such as police and civil society who are more focused on the disaster.

“At the same time, governments may put in place shelters for disaster relief which are often overcrowded and unsafe, without thinking about the risks of sexual violence.

“All of this happens more often and with increased severity in countries that have patriarchal gender norms and where the use of violence against women is widely accepted as normal behaviour.”

Importantly, the researchers believe that climate mitigation and adaptation efforts can and should play an important role in reducing violence against women.

This could include mentioning “violence against women” in Nationally Determined Contributions (the climate change commitments countries make) and allocating finances to address it, or developing Climate Change Gender Action Plans. Samoa and Fiji are two countries which have already done this.

The researchers also advise that violence against women needs to be a consideration in countries’ disaster planning processes.

The study was funded by the Medical Research Council (MRC) and was carried out in collaboration with researchers at the University of Exeter, the South African Medical Research Council and the University of North Carolina at Chapel Hill.
