Desertification has had an acute impact in Africa, particularly in the Community of the Sahel-Saharan States (CEN-SAD), which is characterised by climate ranging from hyper-arid to dry sub-humid. The local communities and their livelihoods are heavily dependent on the increasingly fragile natural resources.
Large areas of the humid tropics are like mosaics, combining features of forests and agriculture and housing hundreds of millions of people. Land uses that store high quantities of carbon, such as agroforestry and other tree-based systems, make up a large part of those mosaic areas.
Leyendo el informe titulado: “El verdadero costo de los agrocombustibles Alimentación,bosques y clima”, podremos descubrir cuán ilógicos, inapropiados y directamente contraproducentes pueden ser estos biocombustibles; cómo están ya trastornando a miles de familias alrededor del mundo, que se ven desalojadas para dar paso a plantaciones de“biomasa”; cómo vastas áreas de bosques están siendo dest
Understanding pasture degradation processes is key for sustainable development in the Amazon region. Pasture degradation can be indexed by pasture nutritional status, which is impacted by environmental and human related factors.
In this paper we investigate the potential production and implications of a global biofuels industry. We develop alternative approaches to consistently introduce land as an economic factor input and in physical terms into a computable general equilibrium framework.
An accurate estimate of carbon fluxes associated with tropical deforestation from the last two decades is needed to balance the global carbon budget. Several studies have already estimated carbon emissions from tropical deforestation, but the estimates vary greatly and are difficult to compare due to differences in data sources, assumptions, and methodologies.
As data sets of multiple types and scales proliferate, it will be increasingly important to be able to flexibly combine them in ways that retain relevant information. A case in point is Amazonia, a large, data-poor region where most whole-basin data sets are limited to understanding land cover interpreted through a variety of remote sensing techniques and sensors.
China has long been experiencing intense land use/cover changes (LUCC). Undesirable land use/cover changes have resulted in widespread land degradation. This study examines the temporal and spatial dynamics of land use change and land degradation as evident from land use survey datasets (1991-2001).
Borneo has experienced heavy deforestation and forest degradation during the past two decades. In this study the Moderate Resolution Imaging Spectroradiometer was used to monitor land cover change in Borneo between 2002 and 2005 in order to assess the current extent of the forest cover, the deforestation rate and the role of fire.
The majority of landscapes around the world have been modified or transformed by human activities to meet the needs of human societies. The loss of native vegetation for agricultural development affects the sustainability of growing proportion of the world's ecosystems.
