  • Land accounts for Europe 1990-2000

    Changes in land cover in Europe reflect modifications in the uses of land, which often compete for the same resource: development of artificial surfaces for housing, transport and economic activities; intensification or extensification of agriculture practices; conversion of natural land to agriculture or farmland abandonment; afforestation or deforestation. Accounting for land cover change in a ...

  • Relationship between Riparian Vegetation and Stream Benthic Communities at Three Spatial Scales

    We examined the influence of riparian vegetation on macroinvertebrate community structure in streams of the Upper Thames River watershed in southwestern Ontario. Thirty-three µ-basins (129–1458 ha) were used to identify land cover variables that influenced stream macroinvertebrates. Micro-basins represented the entire drainage area of study streams and were similar in stream order (first, second) ...

  • Agroforestry Mitigates Climate Change

    Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Farmers' (local and colonists) perceptions of environmental changes in the forest frontier of the upper Amazon, Peru

    Amazon ecosystem degradation profoundly impacts life supporting processes of global importance such as climate regulation, as well as local conditions for livelihoods. In Peru's highland jungle, an expanding deforestation front of forest conversion to agriculture has vastly transformed the landscape. Small–scale farming, the main driver of forest degradation, and consequently household natural ...

  • Soil and water: towards a larger-scale perspective of their relations

    Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...
