New studies highlighted the effects of rapid urbanization on the emergence of zunotic diseases

Around 3.5 billion people live in a messy transition area between cities and wild places, where agricultural homes leave; The suburbs spread in the forest; And humans, wildlife, and livestock easily intrormics. This Wildland-urban Interface (WUI) covers only 5% of the land surface of the Earth, but it is a new study led by the Yale School of the Environment. The habitat can provide.

Researchers said that this study to see how rapid urbanization in WUI could affect the possibility of spreading disease and it suggests how important it is for disease management to limit animal risk and wildland encroachment, especially As the urban population, the researchers said.

The risk in the global south is particularly high where a diverse array of potential hosts and rapid, can leave people especially weak people. Over the next 25 years, population in urban areas is expected to grow 2.5 billion, with 90% of development predicted in Africa and Asia. Research also emphasizes the need to understand the diversity and behavior of wildlife – and the routes through which they interact with people – especially in the tropical.

Ph.D. Rohan Simkin said, “Wildland urban interface is the perfect place to emerge as you have people, livestock and wildlife in the arrangement of land using tightly.” YSE candidates who led the study. “But there are a lot of opportunities as cities grow, and it is especially true in places like Africa and Asia where cities are going to grow rapidly in the next 20 or 30 years, to design cities which these effects A lot of saved from. “

the study, Published In Global change biologyMapped the distribution of about 700 mammals associated with more than 100 different diseases in the global Wui.

“Where there is a high variety of hosts, you have variety of pathogens and more routes, through which people can interact with them,” said simplicity.

Simkin said that the authors were surprised only by how widespread the species known for carrying zunotic diseases. For example, core rat can spread plague and thrive throughout the continents. More than 700 million people live in areas with suitable habitat for 20 or more species, and essentially each person in Wui lives with at least one potential host species, the authors said.

Researchers identified many hotspots, including large population areas, such as some parts of China, or especially expander Wuis, such as Northeast US. He found that most people living in areas with the richest classification of potential wildlife found that most people living in the most rich classification areas Are. In the global south, lower and medium-or-come countries where biodiversity is generally the highest.

These are the areas where the risk of disease can be increased by limited health care, poor hygiene and informal housing – and where future urbanization is expected to be bulk. However, this is also the place where the data is the most limited, they noted.

“We have this real drawback of knowledge around the disease ecology in places where people are really the weakest,” said Eimpack.

The authors said that while addressing that difference, and how many times – people and different hosts interact, it is necessary to map the actual risk of the disease spillover.

Karen Seto’s Frederick C. Hixon Professor, “Karen Seto said,” Urban expansion triafecta in Wildlands, has increased connectivity of people worldwide, and urban development in places with high pathogens will lead Are. “And urbanization science, who co-written the study.
