Projecting land use change impacts on nutrients, sediment and runoff in multiple spatial scales: Business-as-usual vs. stakeholder-informed scenarios
پیش بینی اثرات تغییر کاربری اراضی روی مواد مغذی ، رسوب و رواناب در مقیاس های مکانی مختلف: تجارت معمول در مقابل سناریوهای آگاه از ذینفعان-2020 While the impact of land use/land cover (LULC) change on watersheds has been extensively studied, little
attention has been given to the variability of this impact with respect to the projected LULC scenarios at a
range of spatial scales. Here, a spatial LULC change model was coupled with the Chesapeake Bay
Watershed Model to investigate LULC change impact on nutrients (nitrogen and phosphorous) and
sediment loads and runoff volume in northwestern Virginia, U.S. Using 2011 as the baseline scenario, we
examined four stakeholder-informed future (50 years hence) LULC scenarios, which differed in projection
of population growth and planning strategy, along with a ‘business-as-usual’ (BAU) scenario, which
projected historical LULC trends into the future. Four LULCsdDeveloped, Forest, Grasses and
Cropsdwere dynamically transitioned. The difference in projected nutrient and sediment loads and
runoff volume between the LULC scenarios was greater at finer spatial scales, where planning decisions
are most commonly made. The LULC change scenario with reactive planning and high population growth
resulted in the largest increase in runoff volume, while the scenario with reactive planning and low
population growth showed the largest increase in modeled nutrient and sediment loads. These results
suggested that planning strategy plays a more critical role than population growth in watershed
management. Keywords: Land use/land cover change | Watershed modeling | Nutrient and sediment pollution | Surface runoff |
