Under the prevailing variable natural conditions nomadic pastoralism was the most suitable form of land use in Mongolia and the neighboring countries in the past. Furthermore, small areas were used for agriculture in some regions. Therefore, anthropogenic influence was present throughout history. In the forest steppe zone this led to the disappearance of forest sites which then gave way to mead...

Irrigated croplands in Central Asia are highly prone to land degradation due to their environmentally fragile physical settings and intensive agricultural practices. This study: (i) assesses the state of croplands in irrigated areas in northern Uzbekistan, based on the time series of MODIS-NDVI imagery; (ii) analyzes relationships between the identified trend of cropland degradation and soil qu...

Systematic and comprehensive compilation of land use statistics is necessary for planned development of agriculture, forests, grasslands, rural settlements, urban spreads, industries and other land based programmes and activities. The need for optimizing land use in an integrated manner has become particularly relevant in recent years as a consequence of compelling and conflicting demands of gr...

The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion andsediment estimation one can use statistical and empirical methods. For doing this, land unit map and the map of effectivefactors should be prepared. For erosion and sediment estimation one can use statistical and empirical methods. However,these empirical methods are usually time co...

The United Nations Convention to Combat Desertification and its sister conventions, the United Nations Framework Convention on Climate Change and the Convention on Biological Diversity, all aim to halt or mitigate the deterioration of the ecological processes on which life depends. Sustainable land management (SLM) is fundamental to achieving the goals of all three Conventions. Changes in land ...

In this paper, grid cell based spatial statistics were used to quantify the drivers of land-cover and land-use change (LCLUC) and habitat degradation in a tropical rainforest in Madagascar. First, a spectral database of various land-cover and land-use information was compiled using multi-year field campaign data and photointerpretation of satellite images. Next, residential areas were extracted...

Desertification in arid, semi-arid and dry sub-humid regions is a global environmental problem. Considering theincreasing importance of desertification and its complexity, the necessity of giving attention to desertification criteria andindices is essential. Models and methods such as MEDALUS, UNEP-FAO, and others have been proposed on local andnational scales. In this research, IMDPA was selec...

Newly reclaimed areas cover several patches over different regions of Egypt, which have different specific characteristics related to climate, soils, hydrology, etc... . The mechanical farm, which extends over 10,000 feddans fares from south of Alexandria by 62 Km, could be considered one of the most important reclaimed areas at West of Nubaria affected by degradation due to water logging. The ...

land vulnerable to desertification increased in the mediterranean basin since world war ii dueto several interacting factors including climate variations, land-use changes and growing human pressure. itwas hypothesized that the increase in the level of land vulnerability is not distributed homogeneously overtime and space while impacting preferentially landscapes surrounding large urban agglome...

One of the objectives of agricultural development in Botswana is the increase of agricultural productivity in both arable and livestock production in order to increase farm incomes and thus help to make agriculture a sustainable activity. This paper looks at the challenges that Botswana faces in meeting this objective while minimizing any land degradation that may accompany the process of incre...
