个人简介
Most of Dr. Nearing's work has been in the area of soil erosion and conservation, including the understanding of basic erosion processes, field measurement of erosion rates, and the development and testing of soil erosion models. Recent work focuses on erosion in semi-arid rangeland environments.
Soil is critical to the long-term sustainability of semiarid rangelands. Although research to understand the factors affecting erosion, as well as the on-site and off-site impacts of erosion, have advanced our ability to sustainably manage land, technologies for quantifying and predicting soil erosion on rangelands have not kept pace with applications for agricultural cropland. Changing demographics and population increases in semiarid areas around the world have heightened the awareness of land use impacts and the need for technologies to quantify and predict the impacts of land management on soil erosion. The need for prediction technology is paralleled by the need for decision tools and information delivery mechanisms. We are working to improve the scientific understanding of hillslope and watershed scale erosion, develop new technologies for measuring and monitoring erosion and sediment transport, improve conservation practices on rangelands, improve prediction technologies, and improve technologies for decision making.
Recent work includes: 1) modeling soil erosion at the hillslope scale in western rangelands; 2) using radioactive isotopes to quantify historic rates of soil erosion on rangelands; and 3) documenting the potential effects of future climate change on soil erosion and conservation.
