“…Coupled with changing climate, rapid population growth, economic development and unsustainable land use have increasingly generated pressure on existing land and other resources, which has resulted in remarkable changes and modifications in the spatial distribution of land use/cover in the oases. Despite various attempts to rehabilitate the degraded land and ensure the ecological balance of the oases, the sandy desertification and salinization of the land are the most serious environmental problems occurring widely in these rangelands (Jia et al, 2004;Yang et al, 2005;Zhou et al, 2010), thus threatening the stability and sustainable development of the entire region.…”

Abstract. The combined effects of drought, warming and the changes in land cover have caused severe land degradation for several decades in the extremely arid desert oases of southern Xinjiang, northwest China. Land cover classifications of Landsat images in 1990, 2000 and 2008 were performed based on the multistage supervised classification scheme using the maximum likelihood classifier integrated with conventional vegetation and soil indexes, which improved overall accuracies by 4-5 % compared to the standard classification method. Based on the detection of changes in land cover during 1990-2008 using remote sensing (RS) and a geographic information system (GIS), it can be found that the oasis significantly (+35 %) increased, while the area of ecotone decreased (−43 %). The major trends of the land cover changes were the notable growth of the oasis and the reduction of the desert-oasis ecotone. These changes were mainly a result of the intensified human activities such as land and water exploitation as well as overgrazing. The results of this study indicate that the oasis environment will be deteriorated by increase in potential areas of land degradation if the trend of desert moving further inward and the shrinking of the ecotone continues over the next decades.

“…After all, during thousands of years of oasis evolution, the threats of 20 desertification have consistently occurred and the existence and disappearance of oases are largely related to the abundance or shortage of water resources [Lu et al, 2003;Jia et al, 2004;Zhang et al, 2014]. Thus, unsuitable oasis expansion alongside the inappropriate utilization of water resources will finally result in desertification.…”

“…and the north of the Qinghai-Tibetan Plateau (Figure 1). In this region, oases are the basis of human life and economic development, supporting more than 95% of the population and more 5 than 90% of social wealth with only around 5-6% of the land surface [Han and Meng,1999;Jia et al, 2004]. In Northwest China the stability of the oasis ecosystem directly relates to regional sustainable development and therefore the maintenance and stabilization of the oasis ecosystem is an important research topic.…”

Abstract. There has been substantial expansion of oases in the Northwest of China in recent decades; however, research has largely focused on desertification rather than oasification and its associated mechanisms. Based on the description of desertification in arid regions and other regions, and analysis of oasification in arid or hyper-arid areas, we firstly elucidate the theoretical relationship between oasification and desertification. We then examine the current 5 understanding in oasification research, and propose that this will enhance our understanding of desertification through the integration of studies of oasification. Finally, we suggest three potential topics for future oasification research. We also propose a simple conceptual model for the identification of an appropriate oasis size under different land uses, including the crucial assessment of associated uncertainties. Based on the analysis of oasification research from an 10 epistemological and methodological perspective, we suggest that oasification should have equal research status to desertification in arid regions.

Evaluation of recent land degradation affecting Basra Province, Iraq, resulted in the identification of five prominent environmental degradation processes: desertification, secondary salinization, urbanization, vegetation degradation, and loss of wetlands. This analysis was carried out using '3S' technologies [remote sensing, geographic information system (GIS), and global position system], with the layers extracted and manipulated from available topographic, climatic, and soil maps, as well as satellite image (thematic mapping in 1990 and enhanced thematic mapping in 2003) and field survey data analyses. Rates of conversion were calculated and distribution patterns were mapped with the aid of a GIS. The results revealed that land use changes have affected the wider environment and accelerated land degradation, with severe damage located in southwestern Basra Province representing 28.1 % of the total area. Areas of high to moderate degradation characterize the rest of the south, representing 52.7 % of the total area; while the north of the study region is characterized by very low and low degradation levels accounting for 8.5 and 10.7 %, respectively. Iraq faces serious environmental degradation problems that must be addressed immediately; failure to do so will greatly compound the cost and complexity of later remedial efforts, with environmental degradation beginning even now to pose a major threat to human well-being, especially among the poor.
