Researchers found that natural resources did not limit Cherokee settlement patterns, contradicting long-held assumptions. The studies focused on the year 1721 and used historical data, mathematical models, and statistical inference to analyze town placement and population.
A study of Baltimore's surface soils found a mosaic of soil types, with high chemical variability and differences in potassium, phosphorus levels, and bulk density due to fertilization and trampling. The researchers discovered no relationships between land use and heavy metal levels, instead finding correlations with surface rock types.
A K-State geography professor is researching how land use and land cover changes affect human health and food security. He uses remote sensing technology to monitor the spread of infectious diseases, such as hantavirus, and identify ecological context factors contributing to disease emergence.
Changes in land use have significant effects on the global environment, such as climate and ecosystem functions. In San Mariano, a 48,000-hectare area underwent transformation from forested to intensive rice and maize cultivation.
Scientists at the Woods Hole Research Center have developed high-resolution maps of the built environment for the Chesapeake Bay watershed, capturing impervious surface cover and its implications for biogeochemical and hydrological processes. The new maps are being used to assess water quality and inform restoration efforts in the region.
Research in East Africa highlights the dual nature of land use, with positive impacts on local economies but negative consequences for native plants and wildlife. LUCID project explores links between social systems and environmental changes, aiming to understand why some communities maintain biodiversity despite agricultural expansion.
A recent study by Esaïe Gandonou found that reducing distance to the market has slight positive effects on grain yields and soil conservation. This is largely due to the increased use of artificial fertilizers, which require soil conservation measures.
A new protocol uses path analysis to track the impact of land use on streams, identifying key entities and processes that influence aquatic health. By analyzing 10 watersheds, researchers have developed a valuable approach to understanding the 'land-cover cascade' and its effects on stream ecosystems.
The loss of 6% of mountain gorilla habitat in the Virunga National Park is a significant step backward for the endangered species. Scientists are using NASA satellite imagery to monitor land changes and develop a monitoring system with conservation groups to protect the remaining habitats.
A Princeton University study found that changes in U.S. forests caused by land use practices have increased the emission of smog-producing chemicals from trees, which may have worsened ozone pollution in some parts of the country. The study suggests that intensified tree farming and other land use changes have altered the mix of trees ...
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 ...
The study used high-resolution commercial imagery from the IKONOS satellite to simulate future development scenarios in the Washington-Baltimore metropolitan area. It found a 39% increase in developed land between 1986 and 2000, with significant changes around the Dulles Airport area.
A team of researchers from Penn State is investigating the connection between sedimentation patterns at the river's mouth, land use patterns in the basin, and climate variability. They plan to analyze sediment cores using lead isotope ratios and pollen to link core layers with climate and sedimentary regimes.
