A new analysis of the global dataset shows that low-income countries are very likely to be affected by both toxic pollution and climate change, and the risk of being able to immediately begin direct efforts to reduce pollution risk. Provides a list of high countries. , According to a study published on July 7, 2021 in open access journals PLOS ONE By Richard Marcantonio and his colleagues at the University of Notre Dame, Indiana, USA.

In this era of the Anthropocene, it is clear that human activity is destabilizing our planet across multiple systems. Previous studies show that low-income countries face higher risks than high-income countries. Toxic pollution And climate It changes; however, few studies have investigated the relationship between these two risks.

To test the relationship with toxicity pollution Using data from 176 countries, the authors use three frequently used public datasets: ND-GAIN (Notre Dame Global Adaptation Index), EPI (Yale Environmental Performance Index), and GAHP (Global Alliance On). Health and Pollution) was collated and analyzed. From 2018.

They found strong (rs = -0.798; 95% CI -0.852, -0.727) and statistically significant (cultivated income countries in Africa and Southeast Asia). The author points out that workplace demographic, ecological, and social factors are interrelated. Shows broader patterns of inequality, as well as physical geography, regional structural conditions (such as relatively low capacity for environmental policy and enforcement), and external factors (such as foreign companies that take advantage of deregulation). All exacerbate the risks in these countries. Based on their analysis, the authors create a “target” list of the top 10 countries that can provide the greatest return on investment in risk reduction, based on risk and structural capacity to establish. did. Changes (respectively: Singapore, Rwanda, China, India, Solomon Islands, Bhutan, Botswana, Georgia, South Korea, Thailand).

The data used in this study do not capture all forms of harm or potential risk from toxic pollution or climate change, but only those measured in the first dataset. In addition, the authors state that risks can vary widely from country to country and may require a more detailed domestic assessment to address the impact. However, the immediate findings underscore the need for a global joint approach to the effects of pollution and climate change, while at the same time suggesting an approach to policy makers around the world.

The author adds: “A lot of work is being done to understand the magnitude and distribution of risk. Climate change And toxic pollution, separately. I wanted to know if the spatial distributions of these two types of environmental risks are similar, but unfortunately the results are generally similar. ”
