Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of which are improved cropland and grazing land m...
Unsustainable grazing of animals exerts pressure on a range environmental factors. This review assessed the impacts small ruminants (SRs; sheep and goats) hydrological processes (e.g., runoff occurrence erosion) within European pasture lands. It also considered other effects SRs grazing, such as water pollution. Our research highlights lack evidence-based literature implications by processes. T...
Federal land managers are faced with the task of balancing multiple uses and goals when making decisions about land use and the activities that occur on public lands. Though climate change is now well recognized by federal agencies and their local land and resource managers, it is not yet clear how issues related to climate change will be incorporated into on-the-ground decision making within t...
The effects of four main practices tillage versus no-tillage, and intensive grazing extensive grazing, applied in characteristic agricultural lands Crete Island were evaluated situ using nine soil quality indicators. following representative indicators the rapid visual assessment methodology adopted at European level context EU research project iSQAPER: susceptibility to water wind erosion, sur...
Common lands provide smallholder farmers in Africa with firewood, timber, and feed for livestock, and they are used to complement human diets through the collection of edible nontimber forest products (NTFPs). Farmers have developed coping mechanisms, which they deploy at times of climatic shocks. We aimed to analyze the importance of NTFPs in times of drought and to identify options that could...
Changes to minor patch types in forested landscapes may have large consequences for forest biodiversity. The effects of forest management and environment on these secondary patch types are often poorly understood. For example, do early-to-mid successional minor patch types become more expansive as late successional forest types are fragmented or do they also become more fragmented in managed la...
