“…Therefore, desert riparian plants are always sensitive to the fluctuations in the groundwater table associated with the variations in flood frequency, magnitude, duration, and seasonal discharge (Halik et al., 2019; Keram et al., 2019). These variations in the groundwater table may cause crucial constraints on the structure, distribution, and dynamics of riparian forests if they do not acclimate to this variability (Han, Zhao, Feng, Disse, et al., 2015; Li, Tong, et al., 2019; Schäfer et al., 2017; Ye et al., 2009). Several studies have reported that the contradiction between enlarged irrigated agriculture in the midstream area and degraded groundwater‐dependent natural ecosystem in the downstream sector has become increasingly prominent in the arid and semiarid endorheic river basins in NW China (Ding et al., 2017; Guo et al., 2017; Halik et al., 2019; Wang et al., 2014).…”

“…The use of regression to estimate the influence of ecohydrological parameters is not new (Canedo-Arguelles et al 2016; Han et al 2015). We performed multiple regression analysis to determine which of the cluster-defining ecohydrological attributes were significantly shaping the resultant resource thresholds and their associated threats to the availability of ESs in both the WRS and the DRS.…”

Rapid ecohydrological changes in semi-arid landscapes are increasingly threatening humanity’s life-support systems and eroding many of the ecosystem services (ESs) upon which humans occupying such regions depend. Knowing which services and ecohydrological changes to be most concerned about is indispensable to maintaining the general health of such ecosystems and for developing effective ecosystem management practices. In the semi-arid regions of southwestern Zimbabwe where a large population of rural households depend on ESs extracted from the Colophospermum mopane tree, such understanding may be critical in reversing potential ES losses that may have catastrophic effects on the lives of many. We surveyed a total of 127 rural households who occupy the semi-arid landscapes of the Colophospermum mopane belt in southern Zimbabwe. We assessed the ecohydrological conditions characterising ecosystems where they obtain ES provisioning goods using a number of ecohydrological variables commonly cited in the literature on ecohydrology. Building on principal component analysis (PCA), we employed a hierarchical agglomerative clustering method to create unique clusters of households that depicted different levels of risks or threats associated with their ES provisioning harvesting practices. Multiple regression analysis was further performed to identify significant ecohydrological cluster-defining variables. Our results showed that spatial differences in ecohydrological parameters resulted in four distinct ES resource thresholds depicting four categories of risks that households face in extracting such resources in nearby landscapes. We concluded by proposing a number of landscape restoration or management practices targeted at reversing potential ES losses and subsequently safeguarding the livelihoods of many who depend on ESs.

“…Unfortunately, the impacts of changes in GD resulting from HA are frequently overlooked in arid zones [41]. In regions with low precipitation, GD becomes a crucial variable determining vegetation establishment and mortality [42]. Additionally, GD, influenced by the recharge of shallow aquifers from vegetation transpiration and ecological diversion contributions, plays a nonnegligible role in influencing NDVI changes.…”

Arid zone ecosystems, integral to terrestrial systems, exhibit relatively low stability and are prone to influences from human activities and climate change. To elucidate the influence on the ecological environment of the arid zone by climate change and human activities, the paper takes normalized difference vegetation index (NDVI) as an evaluation index of the ecosystem and uses trend analysis to evaluation of NDVI variation characteristics in the Shiyang River Basin (SRB) from 1990 to 2020. Simultaneously using methods such as partial correlation analysis and residual analysis to evaluate the impact of climate change and human activities on NDVI changes. This study yielded several key findings: (1) The NDVI in the SRB exhibits an increasing trend of 0.034/10a in the interannual variation. (2) The relation cooperatives between NDVI and the deviation of precipitation and temperature in the SRB range from −0.735 to 0.770 and −0.602 to 0.773, respectively. (3) The changes in land use and groundwater depth in the SRB have a certain impact on NDVI changes. (4) The proportion of areas with significant contributions (contribution rate greater than 60%) from climate change and human activities to NDVI change is 33.5% and 22.5%, respectively.
