Researchers in southern China have analyzed the impact of urbanization on local climates, known as the urban dry island (UDI) effects.
A study has found that much of the area of urban America particularly in the Great Lakes region (8.3% of urban area), the Arizona Sun Corridor (7.1%), and Northern California (10.9%) but elsewhere all over the United States (6.2% total) are “urban stream deserts” in which a city is “riverless… due to the effects of human development and population growth”.
The dramatic shift of the earth’s human population to cities is not only straining urban infrastructures, but also the human population itself. Three significant human threats resulting from rapid urbanization in developing countries are increased intense agriculture from the commoditization of food, rising diabetes and heart disease rates, and brain waste of our global youth.
