Desde el inicio de la ocupación española, el Camino del Sur, último tramo de una red a escala continental, constituyó la vía de comunicación entre la ciudad de Buenos Aires y el pago de la Magdalena a la vez que en sus proximidades se originaban incipientes núcleos urbanos.
Un mapa de deforestación del território mexicano, derivado de Ia sobreposición de dos cartografias de uso del suelo y vegetación de 1993 y 2000, se comparo con variables espaciales como el aislamiento (distancias a Ias carreteras y a Ias poblaciones), Ia topografia (altitud y pendiente), el tipo
Using the UNFCCC as a basis, and the objectives of estimating soil organic carbon (SOC) changes during the period 1900–2100, a spatially explicit database of climate, land cover and soil texture was compiled for a 262,000 km2 region in semi-arid Sudan.
The Kalahari ecosystem is characterized by natural resource conflicts and land-use pressure resulting from intensification of human activities.
Amounts of organic carbon in the mineral soil (SOC) and fine-root (
Soil moisture is an important hydrologic variable of great consequence in both natural and agricultural ecosystems. Unfortunately, it is virtually impossible to accurately assess the spatial and temporal variability of surface soil moisture using conventional, point measurement techniques.
The study used a combination of ethno-social surveys and Geographical Information Systems (GIS) to assess 651 pastoral households and their land use under agropastoral production systems in Ogun State, Nigeria. Yields of arable crops on agropastoralists' fields were generally low.
Human-induced desertification in the Horqin sandy land in the north-eastern part of China has been reversed since the mid-1970s through re-vegetation. This land cover change affects surface energy and water transfer processes.
Flow and concentrations of suspended sediment, nitrate-N, phosphate-P, atrazine, and metolachlor were monitored during the spring seasons of 1998 and 1999, primarily during storm events, at a tributary station (Big Ditch) and two main-stem stations (Fisher and Mahomet) of the Upper Sangamon River
