The ‘humped’ soil production function: eroding Arnhem Land, Australia
We report erosion rates and processes, determined from in situ-produced beryllium-10 (Be) and aluminum-26 (Al), across a soil-mantled landscape of Arnhem Land, northern Australia. Soil production rates peak under a soil thickness of about 35 cm and we observe no soil thicknesses between exposed bedrock and this thickness. These results thus quantify a welldefi ned ‘humped’ soil-production funct...
متن کاملLand Degradation
An overview of the Geospatial Methodologies used in order to assess the Soil Erosion Risk by water. 1.2 The damages on Land are traduced in " Soil Erosion " , " Soil Degradation " and/or " Ecosystem Decline " .. Introduction The Soils constitute one of the most important of the world's natural resources. Life on earth is totally dependent on well management of soils (Agurgo, 1996). Into of the ...
متن کاملBattlefields That See
This talk will introduce two new applications of automated video analysis being pursued by DARPA. Video Verification of Identity (VIVID) is concerned with automatically tracking moving vehicles from a moving aircraft and searching the surrounding area for others who may be nearby. Combat Zones That See (CTS) is coordinating the analysis of large numbers of fixed cameras to identify and track ve...
متن کاملNew battlefields for costimulation
Costimulation regulates the activation of naive T cells as they first encounter antigens in the secondary lymphoid organs. But recently characterized costimulatory molecules of the B7 family appear to have roles beyond initial T cell activation. New evidence shows that negative costimulators expressed by tumors and normal tissues afford local protection from T cell-mediated attack.
متن کاملTrade-Offs in Multi-Purpose Land Use under Land Degradation
Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or lost entirely. Finding a sustainable trade-off between food production and one or more of other ecosystem services, given the variety of stakeholders, is a matter of optimizing land use i...
