A team of scientists from Washington State University, in a new study published in the journal, provides an alternative way to understand and minimize the health effects of anthropogenic changes in climate and the environment. To do One earth..

Deepti Singh, an assistant professor of environmental studies based at WSU Vancouver, is the lead author of Climate Change, Air Quality, Agriculture, and public health To propose a “system lens” or scientific approach that links health risks with simultaneous environmental changes caused by human practices.

“The health consequences of air pollution, climate change and agricultural changes are often discussed separately,” Shin said. “But all these issues are related. They have similar causes and each influences each other. Although agricultural activity contributes to air pollution and affects the climate pattern of the region. , Farm production and crop quality are sensitive to air quality and climatic conditions. “

Singh, in collaboration with researchers at Columbia University, the Indian School of Business, Boston University, and Delaware University, has raised multiple issues, although rapid industrialization and modern agricultural practices have helped economic development and increased food production. I studied the situation in South Asia. The dimension of human health.

“We provide a framework for assessing the whole thing. Health effects “It could help identify policies and solutions that have multiple co-benefits to the environment and human health from multiple parts of the Earth’s natural system, all of which are being transformed by human activity at the same time,” said Shin. There is. “

Kyle Davis, co-author and associate professor at the University of Delaware, said:

Scientists reviewed several examples of the health effects of changes in climate, air quality, and agricultural productivity, as well as the co-benefits and unintended consequences of emissions control and water conservation efforts. They see the need for better tools and local high-resolution data on health, weather, emissions, air pollution, and land use in order to better measure human and environmental impacts. I found that I was sharing.

“This study points out useful and effective policy responses that need to take into account multiple factors and interactions, and highlights the problem with a simple explanation,” said Indian School of Business co-author of public policy. Ashwini Chatre, also an associate professor, said.

Landscape changes due to the use of fossil fuels, the burning of crop residues, and the expansion and strengthening of agriculture have contributed to the very poor. Air quality In South Asia, the main source of rainfall, the summer monsoon, has changed, increasing the health risks of nearly a quarter of the world’s population living in the region.

“Late autumn is the’pollution season’of North India and brings a vicious debate to our society about who contributes to it,” said Chatre.

In addition, more frequent and intense heat waves and floods have killed thousands, evacuated millions, reduced labor productivity and caused disease outbreaks. Serious air pollution contributes to increased heart and lung disease, the premature death of millions, and the weakening of monsoon rain. at the same time, Air pollution When Climate change Yields on important food crops have decreased.

“While we may not feel the climatic benefits of reducing greenhouse gas emissions we are doing today for decades, our approach is to minimize human impact. It sheds light on some of the direct health benefits and unintended consequences of targeted policies. climate And the environment. ”
