Multitemporal 1 km NOAA/AVHRR Normalized Difference Vegetation Index (NDVI) maximum composite imagery was utilized in combination with rainfall, soil types, and field survey data on dominant rural activities to assess the risk of land degradation in southern Mauritania. Mauritania is one of eight continental West African Sahel countries that stretch from Chad to the northwestern Atlantic coast, and from the southern fringe of the Sahara Desert to the northern limit of the Sudanian climatic zone.

BACKGROUND: Ethiopia encompasses an extraordinary number of ecological zones and plant diversity. However, the diversity of plants is highly threatened due to lack of institutional capacity, population pressure, land degradation and deforestation. An adequate documentation of these plants also has not been conducted. The farmers in Ethiopia face serious and growing food insecurity caused by drought, land degradation and climate change. Thus, rural communities are dependent on underutilized wild edible plants to meet their food and nutritional needs.

No processo de reforma agrária brasileiro é comum a redistribuição de terra ocorrer por meio de invasões das grandes proprieades pelos sem terra. Esse mecanismo introduz insegurança no direito de propriedade fundiária e, na Regîão Amazônica, tem como consequência o excesso de desflorestamento. Esse trabalho utiliza um jogo não-cooperativo para mostrar que as interações estratégicas entre proprietários e posseiros em um contexto instittucional onde as florestas naturais são consideradas como recursos de livre acesso implicam o excesso de desflorestamento.

This study looks at wood curio carving in Victoria Falls, Zimbabwe, Africa. Although the local people, Ndebele and Shona, have always carved, they now face a weakened economy, due in large part to land reforms in 2000. Thus, more people sculpt wood as a form of livelihood. As one man said “Starvation taught me art”. As a result, gender roles are shifting as men and women begin to enter realms previously reserved for the other. Environmentally, carvers poaching trees deforests the woodlands. As more individuals turn to making crafts sustainability deteriorates.

In this paper we analyse the extent of fire-induced forest degradation in Mato Grosso State, Brazil. We utilise a sample based approach used in a previous pan-tropical deforestation survey to derive information on land cover and burned areas in the two major biomes of Mato Grosso: Amazon and Cerrado. Land cover and burned area are mapped for three years (2000–2005–2010) over 77 sample sites (10000ha each) distributed systematically throughout the state which covers 90.337 Mha.

In rural areas, land use and cover change is often the cumulative result of individual farmer decisions. The goal was to construct a spatial typology of farming systems and assess their influence on the extent and spatial distribution of deforestation, forest re-growth, and agriculture expansion in southern Chile between 1999 and 2007. We present a farm typology and its spatial rendering through the combination of farm-cadastral information and land cover and change data. Using multivariate statistical methods, four types were identified.

AIM: To evaluate trend analysis of earth observation (EO) dense time series as a new way of describing and mapping changes in ecosystem functioning at regional to global scales. Spatio‐temporal patterns of change covering 1982–2011 are discussed in the context of changes in land use and land cover (LULCC). LOCATION: Global.

Reducing emissions from deforestation and forest degradation in developing countries (REDD+) is regarded by its proponents as one of the more efficient and cost effective ways to mitigate climate change. There was further progress toward the implementation of this mechanism at the 16th Conference of Parties (COP) in Cancun in December 2010. Many countries in southern African, including South Africa, have not been integrated (do not participate) into the UN-REDD+ programme, probably due to their low forest cover and national rates of deforestation.

The Dadia forest complex, in the Evros prefecture, in north eastern Greece was designated as a nature reserve in 1980 in order to protect the black vulture (Aegypius monachus) and other raptors. In this paper, the impacts of the protection on the forest growth were assessed using geographic information system (GIS) technologies. The major requirement for almost all research needed for sustainable forest management is extensive and intensive monitoring. GIS is a convenient tool for integrating remotely sensed data and various other kinds geo-referenced data.

Combining spatially explicit land cover data from remote-sensing and faunal data from field observations is increasingly applied for landscape-scale habitat and biodiversity assessments, but without modelling changes quantitatively over time. In a novel approach, we used a long-term time series including historical map data to predict the influence of one century of tropical forest change on keystone species or indicator groups in the Kakamega–Nandi forests, western Kenya.

Although the literature is full of references to soil degradation under forest cultivation, very little information is available on changes in soil properties following deforestation of the Hyrcanian area in northern Iran. Also, the literature provides little information on the effects of conversion from deforested cropland to grazing, a likely direction of land-use change in northern Iran. The objective of this study was to assess the effect of conversion of native forests into farmlands and/or grazing lands on soil properties and nutrients in the Hyrcanian forest.

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. A growing body of work, however, indicates that the future state of much of Amazonia depends on the land use to which converted areas are put, but land use in the tropics is difficult to assess from remotely sensed data alone.
