On the vulnerability of oasis forest to changing environmental conditions: perspectives from tree rings

characterize spatiotemporal patterns and changes in forest growth to gain insights into oasis vulnerability with respect to environmental changes

The radial growth of poplar trees in Ejina Oasis did not follow the variation of streamflow coming from the middle reach, (2) the poplar tree-ring growth did not change in the same way from one site to the other, and (3) the spatial pattern in poplar tree-ring growth were different before and after the 1950s

Oasis land-use change and its environmental impact in Jinta Oasis, arid northwestern China

Detect changes in land-use and to assess its impacts on the environment in Jinta Oasis

Changes in land-use occur within the whole oasis over the study period and result in severe problems of environmental degradation (i.e. land desertification, decline of groundwater, and vegetation degeneracy).

Desert acridian fauna (Orthoptera, Acridomorpha): Comparison between steppic and oasian habitats in Algeria

Variation of Orthoptera diversity among different enviromental variables

The authors highlighted within the oases two acridian assemblages, which are both different from those observed on the level of the steppes. In the wet biotopes of the oases, the most frequent phenology is the usual one retrieved in non-Mediterranean temperate areas

Evaluation of oasis ecosystem risk by reliability theory in an arid area: A case
study in the Shiyang River Basin, China

The reliability indicator 0.686 shows the oasis security is low. The recoverability indicator 0.500 implies that the probability of the oasis’s recovering to the safe state is low when it is in the unsafe state, only 50%. The stability indicator 0.743 means the assuring ratio of water resources in the oasis ecosystem is 74.3%. The integrated loss indicator 0.301 means the accumulative ecological damage is serious. Accumulative damage area is 30.1% of the total oasis area because of the uncertainty of water resources.

Plant genetic diversity, irrigation and nutrient cycling in traditional mountain oases of northern Oman

Plant Nutrition for food security, human health and environmental protection

Nutrient fluxes in complex, small scale crop rotations such as practiced in intensively irrigated desert oasis systems of eastern Arabia

The results show that the sustainability of these irrigated landuse systems depends on a high quality of the irrigation water with low Na but high CaCO3, intensive recycling of manure and an elaborate terrace structure with a well tailored water management system that allows adequate drainage

Ecology and morphological traits of an ancient Musa acuminata cultivar from a mountain oasis of Oman

The highwater storage capacity of the calcareous rocks in these mountain ranges may have allowed the survival of ancient germplasm of banana, a drought sensitive perennial in some remote niche environments

The role of Oman’s oases as in situ conservation centers for ancient germplasm The apparent absence of black sikatoga (caused by Mycosphaerella fijiensis) and panama disease (caused by Fusarium oxysporum f.sp. cubense [Foc]) in banana in the whole of Wadi Tiwi makes this an all the more interesting area of further research on banana diversity with a potential to discover germplasm with tolerance traits against both widely devastating diseases

Agricultural, architectural and archaeological evidence for the role and ecological adaptation of a scattered mountain oasis in Oman

The economic and infrastructural basis of the agro-pastoral-piscicultural society which likely has constructed them

As a scattered agro-pastoral settlement with a recently built central housing area, a large number of tiny terrace systems cultivated with date palms and a flexible area of wheat irrigated for a few months, the Maqta territory represents an extreme case of human adaptation to a xeric mountain environment in Northern Oman

WATER ENVIRONMENTAL DEGRADATION OF THE HEIHE RIVER BASIN IN ARID NORTHWESTERN CHINA

Environmental Monitoring and Assessment

An investigation on the water environmental degradation in the Heihe River Basin and analysis of its causation were conducted

The results indicated that water environmental changes in the whole basin were tremendous mostly in the middle reaches, which reflected in surface water runoff change, decline of groundwater table and degeneration of surface water and groundwater quality

The objectives of this study are to monitor and characterize the dynamic change patterns of sandy desertification from 1993 to 2002 according to different land-use patterns, and identify the driving forces of sandy desertification development

The sandy land landscape changed significantly and desertified land has expanded rapidly from 1993 to 2002.

Oasis land-use dynamics and its influence on the oasis environment in Xinjiang, China

The oasis landscape change and its driving forces for a selected research area (150 Regiment in Shihezi District, Xinjiang Uygur Autonomous Region) from 1982 to 1995 were studied using landscape ecological analysis methods.

landscape matrix was changed from cropland (1982) to wasted grassland (1995); areas of wasted grassland, forested land, and residential land had been increased while other types decreased, among which sand land, cultivated land, and abandoned cultivated land declined dramatically; transition probabilities of vegetable land, abandoned cultivated land, orchard, and sand land patches were over 40%, while wasted grassland and cropland were about 20%

The modifiable areal unit problem of spatial heterogeneity of plant community in the transitional zone between oasis and desert using semivariance analysis

Semivariance analysis was used to evaluate the spatial characteristics of plant community in the transitional zone between oasis and desert

The parameters of spatial heterogeneity change with spatial scales and zoning approaches and hence there is evidence of scale and zoning effect related to the MAUP among the various aggregations.

Playa-like sediment archive near the oasis of Maqta, situated at the upper end of the Wadi Khabbah in the Jabal Bani Jabir mountains (Hajar range) of northern Oman

The Glacial to Lateglacial was characterized by arid conditions with a following transitional period of even less rainfall. At 10.5 ka, sedimentation rates increases abruptly, indicating the onset of the early Holocene humid period (EHHP). Rainfall reaches its maximum at 9–8 ka (EHHP-2) and a decreasing sedimentation rate after 8 ka characterizes the arid period of the middle to late Holocene.

Migration, agricultural transformations and natural resource exploitation in the oases of Morocco and Tunisia

This report presents the main findings of the IMAROM project (Interaction between Migration,
Land and Water Management and Resource Exploitation in the Oases of the Maghreb). IMAROM is an interdisciplinary, EC-funded research project studying the impact of migration and concomitant socio-economic and political changes on land and water management and resource exploitation in the oases of Morocco and Tunisia

This research has been achieved via systematic research by comparing socio-economic, agricultural, and environmental developments in several oases located in southern Morocco and Tunisia.

The IMAROM research project has clearly demonstrated the potentials of migration for agricultural development. Although migration can impossibly be the only agent promoting development in oases, and its role should not be overstated, it has at least the potential to contribute substantially to agricultural development, by providing the necessary investment capital in a context where credit and insurance markets are hardly accessible for most households.

This report presents the main findings of the IMAROM project (Interaction between Migration,
Land and Water Management and Resource Exploitation in the Oases of the Maghreb). IMAROM is an interdisciplinary, EC-funded research project studying the impact of migration and concomitant socio-economic and political changes on land and water management and resource exploitation in the oases of Morocco and Tunisia

This research has been achieved via systematic research by comparing socio-economic, agricultural, and environmental developments in several oases located in southern Morocco and Tunisia.

The IMAROM research project has clearly demonstrated the potentials of migration for agricultural development. Although migration can impossibly be the only agent promoting development in oases, and its role should not be overstated, it has at least the potential to contribute substantially to agricultural development, by providing the necessary investment capital in a context where credit and insurance markets are hardly accessible for most households.
