Article history: Received 2 July 2016 Received in revised form 4 December 2016 Accepted 29 December 2016 Available online 25 January 2017 Accurately monitoring global vegetation dynamics with modern remote sensing is critical for understanding the functions and processes of the biosphere and its interactions with the planetary climate. The MODerate resolution Imaging Spectroradiometer (MODIS) v...

Because of frequent cloud cover in these regions, active microwave imagery such as the ERS-1 SAR is preferred over high-resolution visible and near infrared spaceborne sensors for nionitoring landscape degradation. Nevertheless, because rain forest and savanna vegetation cover such vast regions, AVH[RR and its derivative vegetation indices are frequently used for medium or low-resolution monito...

this study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. the study was carried out in steppe rangelands of saveh, markazi province, iran. four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. to study various vegetation and...

The importance of accurately monitoring rangeland degradation dynamics over decades is increasing in Linxia rangeland, the birthplace of the Yellow River in China. Since 2000, the Chinese government has implemented the “Grain for Green” program and enforced a grazing ban in Gansu province, one of the most degraded provinces, to mitigate the problem of rangeland degradation. The effects of these...

The Irano-Touranian biogeography region is exposed to degradation because of anthropogenic activities and overgrazing. One of the important indirect applications of this ecosystem is Apiculture, which can be considered for reduce degradation of land and over coming for indigenous people, that were live in this area. It is possible to increase Apicultural ability in an appropriate area by identi...

The savannas of Southern Africa are an important dryland ecosystem as they cover up to 54% of the landscape and support a rich variety of biodiversity. This paper evaluates landscape change in savanna vegetation along Chobe Riverfront within Chobe National Park Botswana, from 1982 to 2011 to understand what change may be occurring in land cover. Classifying land cover in savanna environments is...

Vegetation coverage can be inappropriately used, especially in the absence of proper planning, and can result in a reduction of the occupied area. Demographic and economic alterations are factors that contribute to the degradation of vegetation coverage in landscape units. In addition, because vegetation is essential for protection of recharge areas in aquifers, the fragmentation of habitats in...
