A new study found that a slowing of population growth could contribute to reducing greenhouse gas emissions, with slower growth paths by 2050 accounting for 16-29% of necessary emissions reductions. Urbanization and aging also play significant roles in shaping future emissions.
A team of scientists finds that global warming is unlikely to expand the range of malaria due to effective control measures, urbanization and economic development. Malaria control efforts have reduced the disease's prevalence over the past century despite a global temperature rise.
A new study reveals that urban growth and agricultural exports are major drivers of tropical deforestation, contrary to previous assumptions. The study found that industrial-scale clearing in countries like Brazil, Indonesia, and Cambodia is driven by demand for products like palm oil, soybeans, and meat.
Monsoon rainfall has decreased over the past 50 years in rural areas with increased irrigation in northern India, while urban areas have seen an increase in heavy rainfall. This shift is attributed to landscape changes and cooling effects on low-pressure systems necessary for monsoons to progress.
A Dutch study finds that expanding communities and municipalities leads to a 'dilution' of citizen protests, with densely populated areas experiencing more opposition against disappearing green spaces. Concerned citizens are often well-educated and personally invested in the areas affected.
A six-year study found that urban areas attract lower-quality Acadian Flycatcher birds, which have reduced nesting success. These birds are more likely to fail or abandon their nests and return year after year.
A new study from Harvard University and colleagues challenges previous knowledge about the origins of urbanization, proposing that smaller groups made decisions leading to city growth. The research analyzed artifacts at Tell Brak in Mesopotamia over an 800-year period, revealing patterns of population growth and settlement clusters.
A study on European blackbirds found that urbanization favors sedentary males, with those exhibiting lower migratory disposition having an earlier onset of reproductive season. This is due to the advantages of sedentariness and earlier territory establishment for males in terms of reproductive success.
Researchers found that a one-mile stretch of National Forest significantly reduced chemical pollutants and improved bacterial populations in a stream. The study suggests that undeveloped forest sections can mitigate the effects of urbanization on water quality.
The UN model predicts 60.8% of people will live in towns and cities by 2030, but a new model suggests this number is lower at 49.2%. Most population growth between 2025-2030 will come from 10 large developing countries.
A new study by Georgia Institute of Technology researchers found that China's rapid urbanization has led to a significant increase in the region's surface temperature, with a mean rise of 0.09 degrees Fahrenheit per decade since 1979. The nighttime low temperatures have also risen faster than daytime high temperatures, resulting in an ...
Research shows that cities built on fertile lands account for a significant decline in global food production, despite covering only 3% of US land area. Urbanization leads to a 1.6% reduction in annual Net Primary Productivity, offsetting gains from increased agricultural lands.
A NASA study reveals that urbanization can reduce annual photosynthetic productivity in some areas by up to 20 days. However, research also shows that human activity can increase productivity in resource-limited regions through land transformation.
