Argentina

Patterns of land-use and land-cover change are usually grouped into one of two categories defined by the dominant trend: (1) deforestation resulting from expanding agriculture and (2) forest expansion, usually related to the abandonment of marginal lands. At regional scale, however, both processes can occur simultaneously even in the absence of net change.

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.

SUMMARYZambia has one of the largest forest resources in southern Africa with almost 66% of its land mass under forest cover. However, indiscriminate harvesting of valuable timber resources for commodity-type products such as sawn-timber, charcoal and fuel-wood are the main drivers of forest depletion.

Geographic information systems and remote sensing technologies have become an important tool for visualizing conservation management and developing solutions to problems associated with conservation. When multiple organizations separately develop spatial data representations of protected areas, implicit error arises due to variation between data sets.

Land use and land cover change (LUCC) models frequently employ different accessibility measures as a proxy for human influence on land change processes. Here, we simulate deforestation in Peruvian Amazonia and evaluate different accessibility measures as LUCC model inputs. We demonstrate how the selection, and different combinations, of accessibility measures impact simulation results.

The real tool for achieving of sustainable development is an integrated landscape management. It was defined by Agenda21. It means an integrated approach to planning and to management of landscape resources. In the Slovak Republic the concept of integrated landscape management overcames development on the theoretical-methodological, conceptual and implementational sites.

Decades of heavy-cutting and high-grading in the northeastern United States provide an opportunity for rehabilitation and increased carbon stores, yet few studies have examined the feasibility of using carbon markets to restore high-graded forests. We evaluated the effectiveness of rehabilitation on 391 ha of high-graded forest in Vermont, USA.

This paper is a critical synthesis of the causes, effects and challenges of the Sahelian droughts. The results show that the four main causes of the Sahelian droughts are as follows: sea surface temperature changes, vegetation and land degradation, dust feedbacks and human-induced climate change.

Biogeocenosis study of the status and biological diversity of forest plantations (FP) of the eastern regions of Volga are held from 2010. The different FP types were allocated and described. Ravine and beam-type forest land are not used in agriculture. The age of FP on them ranges from 30-65 years. Scots pine and common birch mainly grow as I quality class (QC), English oak - like II QC.
