Editor´s Choice March 2012

Human impact on the landscape through alteration of vegetation is occurring globally, with conversion of natural ecosystems for food production, industry and urban areas (Foley et al. 2005). However, one of the challenges for accurately assessing these impacts is the fact that the vast majority of our ecosystems have already been modified in some way. As such, it is difficult to know what the original impacts have been from land and forest clearing that occurred in these systems at least a century ago.  Perhaps even more complicated is trying to understand the impact on adjacent intact ecosystems, particularly non-point source changes in nutrient availability and biogeochemical cycling, which are critical components for understanding the integrated impact of land-use change on the landscape (Buffam et al. 2011). For example, eolian dust deposition due to human activity has increased markedly with the increase of agricultural expansion in North America (Neff et al. 2008), but at present, it is far from clear how ecosystems have been impacted from these alterations in nutrient pools and turnover.
