Agro-pastoral decline in European mountain areas has recently caused changes to traditional landscapes with negative consequences on semi-natural grassland conservation and the associated biodiversity and ecosystem services. In the Italian Alps, grassland patches enclosed in a forest matrix are progressively disappearing.

Australia

Reports of positive or neutral effects of grazing on plant species richness have prompted calls for livestock grazing to be used as a tool for managing land for conservation. Grazing effects, however, are likely to vary among different response variables, types, and intensity of grazing, and across abiotic conditions.

The need to maintain or increase livestock mobility in arid Africa has been widely embraced by ecologists, social scientists, and more recently regional governments. These movements are seen to sustain livestock production under a highly variable and changing climate. At the same time, livestock mobility is threatened by the expansion of agriculture onto rangelands.

Much of the coastal sage scrub habitat in Southern California that existed prior to European settlement has been developed for human uses. Over the past two to three decades, public agencies and land conservation organizations have worked to acquire some of the remaining lands for preservation.

critical re-evaluation of controls on spatial and seasonal variations in nitrate concentrations in river waters throughout the River Derwent catchment in North Yorkshire, UK

Since mean nitrate concentration along single river channels increases significantly with percent arable land use upstream of sampling points and autumn/early winter flushes in nitrate concentration are widespread, it is generally concluded that farmers contribute most of the nitrate.

Due to the progressive forest expansion in European mountain areas triggered by agricultural abandonment, semi-natural meadows and pastures of great ecological and aesthetic value are disappearing. The aim of this study is to predict and analyse the future evolution of land use and land cover (LULC) in the Stubai Valley, Central Alps.
