Recently, whether drylands of Northwest China (NW) have become wetting has been attracting surging attentions. By comparing the Standard Precipitation Evapotranspiration Indices (SPEI) derived from two different potential evapotranspiration estimates, i.e., Thornthwaite algorithm (SPEI_th) and Penman-Monteith equation (SPEI_pm), we try to resolve controversy. The analysis indicated that air tem...

There are several possibilities for increasing the income of farmers. different strategies crop productions states/regions and they location-specific. The performance agriculture sector depends on rainfall, climate change, resource scarcity, changing demand pattern food products many more uncertainties. Particularly, Jath tehsil is a drought-prone it has almost all area as dryland area. farmers...

Climate change is expected to have important implications for human mobility. This article discusses and contextualizes key insights from a recently published study by Thalheimer, Williams, van der Geest, Otto in Earth's Future (2021), https://doi.org/10.1029/2020EF001958. The authors synthesize findings the climate science impact literature, among others IPCC Special Report on Global Warming o...

Abstract Background A review of the literature was carried out to study dust and sandstorm (DSS) in terms its ecosystem processes relationship other dryland disasters Northeast Asia. Drylands are ecosystems that include grasslands, semi-deserts, deserts, these types vulnerable due their low primary productivity depends on a small amount precipitation. Results Drought, dust, desertification, win...

Previous research on the effects of drought vegetation productivity seldom distinguished different responses ecosystems to under management practices and land use systems. Studies investigating whether irrigation can buffer negative impacts usually used discontinuous yield data in distribution. In this study, trends farmlands drylands northern China (DNC) from 2000 2018 were studied using self-...

Abstract The response of terrestrial water storages to dryland vegetation growth remains poorly understood. Using multiple proxies from satellite observations and model outputs, we show an overall increase (decrease) in (terrestrial storages) across drylands globally during 1982–2016. Terrestrial greening correlate negatively with growth, particularly for cropland-dominated regions, such is pro...

Abstract Context Effectively estimating the influences of urban expansion on multiple ecosystem services (ESs) is great importance for improving planning in drylands. However, there are some shortcomings existing models, which lead to uncertainties assessment ESs. Objectives This study sought effectively estimate ESs Methods We combined land use scenario dynamics-urban model and ES models habit...
