Objectives of the
Develop low and moderate resolution data in GIS and other formats necessary
to describe soil properties, vegetation type and cover, topography, climate,
and farming practices required for simulating wind erosion and transport
of fugitive dust across the Columbia Plateau.
2. Quantify fluxes and develop or verify prediction capabilities of wind erosion and PM10 / PM2.5 emissions from agricultural lands in the Columbia Plateau necessary for providing input data into a regional fugitive dust transport scheme.
3. Create an emissions inventory for the Columbia Plateau that will illuminate areas most susceptible to fugitive dust emissions and which can then be targeted for implementing alternative control strategies and USDA Natural Resources Conservation Service conservation programs.
4. Develop a regional convection-dispersion-deposition model for predicting spatial and temporal variations in PM10 / PM2.5 concentrations as well as the impact of changing land use and farming practices on these concentrations across the Columbia Plateau.
5. Develop and evaluate, through long-term cropping systems research and other field experiments, the agronomic feasibility of alternative tillage and cropping systems that reduce dust emissions from dryland and irrigated agriculture fields in the Columbia Plateau.
6. Determine whether changes in farming methods have occurred since the inception of the Columbia Plateau PM10 Project that will result in reduced wind erosion and fugitive dust emissions.
7. Identify sustainable farming practices for the Columbia Plateau by considering the economic, social and soil quality benefits of alternative tillage and cropping practices in reducing fugitive dust emissions.
8. Develop awareness and acceptance of best management practices via on-farm testing of improved technologies in farmers’ fields, extension outreach programs, and other educational materials.
