Abstract (sommario):

In this paper, using the wavelet technique we analysed rainfall behaviour in the country across different agro-climatic zones over a century. Findings indicate that at the national level there is no significant trend in rainfall in the long run, but there are pockets of change in the rainfall pattern. There was a significant increase in the rainfall in the arid zone, whereas in the humid, semi-arid tropics and semi-arid temperate zones the trend was downward but insignificant. The behaviour of rainfall was different during this period. Except in the arid zone, we find a similar trend in other

Abstract (sommario):

This study has investigated the effect of south- and north-facing hillslopes (SFS and NFS, respectively) on soil and vegetation properties along a climatic transect that covers four climatic zones: Mediterranean, semiarid, arid, and extreme-arid. The results indicate that differences between NFS and SFS in organic matter and soil moisture contents were significantly higher in the Mediterranean zone than in any other site along the climatic transect, particularly at the end of the rainy season. Both soil properties were higher on NFS than on SFS. Similarly, differences between the opposite hill

Abstract (sommario):

Despite the fact that gross primary productivity (GPP) and water use efficiency (WUE) have been widely used as indicators to evaluate the water-carbon cycle, uncertainties exist in the patterns of GPP and WUE responses to climate variability along different aridity gradients. In this study, the aridity index was used to divide China into four arid-humid zones. The spatiotemporal variability of multiple vegetation types GPP and WUE in response to climate change under different arid-humid zones were investigated based on remote sensing data. The results indicated that the increasing trend of WUE

Abstract (sommario):

SUMMARYThe arid zone of northwestern India is a unique adaptation zone for crop plants because of its pervasive severe moisture stress and high temperatures. Pearl millet (Pennisetum glaucum) is a major cereal in this zone as it represents approximately 25% of the total acreage of the crop in the country. Pearl millet hybrid cultivars, which have gained widespread acceptance from farmers elsewhere in the country, have not been adopted in the arid zone. Farmers continue to sow their traditional landraces because the yield advantage of current hybrids is not expressed in this zone, and the risk

Abstract. The flow records of arid zone rivers are characterised by a high degree of seasonal variability, being dominated by long periods of very low or zero flow. Discrete flow events in these rivers are influenced by aseasonal factors such as global climate forcings. The atmospheric circulations of the El-Niño Southern Oscillation (ENSO) have been shown to influence climate regimes across many parts of the world. Strong teleconnections between changing ENSO regimes and discharges are likely to be observed in highly variable arid zones. In this paper, the influence of ENSO mechanisms on the

Abstract (sommario):

The arid region in India is spread over 3,17,090 sq km, of which 70,300 sq km is classified as cold arid and the remaining is hot arid region. Western Rajasthan alone carries the onus of nearly 61% of hot arid lands in India. In this region, biotic pressure is high and resource base both in terms of soil and rainfall is poor. The mean annual rainfall varies from 4 5 0 to 400 mm and longest crop growth period available is

Abstract (sommario):

The forest plays a vital role in the biological, ecological and economic balance in our country. It is the result of millenary interactions between the climate, the diversity of geological and edaphic contexts. The objective of this study was to determine and evaluate the physicochemical parameters of forest soils in two zones of the Djebel El Ouahch (Constantine) national park, which were exposed to two bioclimatic stages (sub-humid and semi-arid). The samples were taken at a depth between 0 and 20 cm in each zone on sampling stations of 400 m2. Our results showed that the bioclimatic stage a

Abstract (sommario):

The realization of regional sustainable development has been a popular research topic during the process of urbanization. To explore the coordination relationships between urban development and ecological security—taking Urumqi city, a representative arid city in Xinjiang, China, as a study area—this study has constructed a framework of spatial suitability evaluation based on the characteristics of a Mountain–Oasis–Desert System (MODS) in an arid area under the framework of major function oriented zoning (MFOZ). A spatial overlay analysis using Geographic Information System (GIS) with a 5 m ×

Abstract (sommario):

Because of evapo-transpiration, compacted loess road embankments were considered to be in a partially saturated state in both arid and semi-arid regions. Based on previous studies and the theory of unsaturated soil mechanics, a numerical analysis of rainfall infiltration in a compacted loess road embankment was conducted. The transient seepage characteristics and moisture migration patterns of the moisture in the embankment were analysed. The results showed that after precipitation, the moisture profile of the compacted loess could be separated into three zones .The data also showed that: unde

Abstract (sommario):

Rangeland deterioration and restoration management has been one of the prominent issues. The present study focuses on the composition, cover, and yields accumulation of rangeland plant species from different ecological zones and subzones. Pasture yield in Mongolia varies in ecological zones and subzones (p≥0.001), so 39 sheep, during the summer, comfortably graze in one-hectare area in high mountain zone, - 72 in forest steppe, 21 in steppe and 13 in arid steppe area respectively. Whereas types and cover of plant species in high mountain rangelands are more than other areas, yield accumulation

Abstract (sommario):

Australia’s deserts can appear to be desolate and harsh environments, but they are extremely dynamic places that support a range of species adapted to the boom and bust conditions. Despite the resilience of the arid zone, extinction rates in arid Australia are the highest in the country and the majority of medium-sized mammals have been lost since European settlement. Katherine Moseby is a conservation biologist who lives and works in the Australian arid zone, with a particular focus on threatened species and reintroductions. She provides a brief background on arid zone ecology in Australia an

Abstract (sommario):

The North China agro–pastoral zone is a large, ecologically fragile zone in the arid and semi-arid regions. Quantitative remote sensing inversion of soil organic carbon (SOC) in this region can facilitate understanding of the current status of degraded land restoration and provide data support for carbon cycling research in the region. Deep learning (DNN) for SOC inversion has been W.a hot topic over the past decade, but there have been few studies at the regional scale in the arid and semi-arid zones. In this study, a DNN model with five hidden layers and five skip connections was established
