Aeolian processes affect the biosphere in a wide variety of contexts, including landform evolution, biogeochemical cycles, regional climate, human health, and desertification. Collectively, research on aeolian is developing rapidly many diverse specialized areas, but integration these recent advances needed to better address management issues set future priorities. Here we review literature their interactions with biosphere, focusing (1) geography dust emissions, (2) impacts, interactions,...
Ecological conservation and restoration are necessary to mitigate environmental degradation problems. China has taken great efforts in such actions. To understand the ecological transition during 2000-2010 China, this study analysed trends vegetation change using remote sensing linear regression. Climate socioeconomic factors were included screen driving forces for correlation or comparative analyses. Our results indicated that experienced both greening (restoration) browning (degradation)...
Abstract Risks associated with dust hazards are often underappreciated, a gap between the knowledge pool and public awareness that can be costly for impacted communities. This study reviews emission sources chemical, physical, biological characteristics of airborne soil particles (dust) their effects on human environmental health safety in Pan‐American region. American originates from both local (western United States, northern Mexico, Peru, Bolivia, Chile, Argentina) long‐range transport...
As public service facilities, urban parks offer many benefits for daily life and social activities residents. However, the accessibility of to residents is often unevenly distributed in spaces that cannot be utilized fully. Here, we used Beijing, China as a case study examined relationship between park population distribution at different administrative levels. Gini coefficient Lorenz curve were evaluate equity accessibility, location quotient was identify spatial difference resident...
Globally, grasslands, covering about 40% of the Earth's land area, are vital for supporting important ecosystem functions, services, and livelihoods millions humans. Currently, grassland degradation is a major threat to maintenance ecological services,1Bardgett R.D. Bullock J.M. Lavorel S. et al.Combatting global degradation.Nat. Rev. Earth Environ. 2021; 2: 720-735Crossref Scopus (47) Google Scholar food security, sustainable development, directly hinders efforts with meeting goals targets...
Aeolian transport is an important characteristic of many arid and semiarid regions worldwide that affects dust emission ecosystem processes. The purpose this paper to evaluate a recent model aeolian in the presence vegetation. This approach differs from previous models by accounting for how vegetation distribution shear velocity on surface rather than merely calculating average effect or simply using empirical relationships. Vegetation, soil, meteorological data at 65 field sites with...
Abstract Soil physical properties and soil organic carbon (SOC) are considered as important factors of quality. Arable land, grassland, forest land coexist in the saline-alkali reclamation area Yellow River Delta (YRD), China. Such different uses strongly influence services ecosystem to induce degradation loss. The objective this study is evaluate variation texture, aggregates stability, affected by uses. For each use unit, we collected samples from five replicated plots “S” shape profiles...
It is well documented that wind redistributes and transports soil resources in semiarid ecosystems. However, fewer studies have quantitatively linked erosion to detailed grain‐size fractions associated nutrient content surface windblown sediment. In this study, we examined (1) the effects of enhanced on particle‐size distribution (2) carbon (C) nitrogen (N) characteristics sediments a typical desert grassland southern New Mexico. Our results show has become noticeably coarser over 2‐year...
Abstract Many grass‐dominated ecosystems in dryland regions have experienced increasing woody plant density and abundance during the past century. In many cases, this process has led to land degradation declines ecosystem functions. An example is Chihuahuan Desert southwestern United States, which different stages of shrub encroachment 150 years. Among a wide variety mechanisms explain grass–shrub transitions system, soil erosion (both wind water) fire are particularly well studied. Here, we...

This study provides a fast and easy‐to‐apply method to estimate threshold friction velocity (TFV) of wind erosion in the field. Wind tunnel experiments variety ground measurements including air gun, pocket penetrometer, torvane, roughness chain were conducted Moab, Utah cross‐validated Mojave Desert, California. Patterns between TFV examined identify optimum for estimating TFV. The results show that TFVs best predicted using gun penetrometer Moab sites. empirical method, however,...
Many arid grassland communities are changing from grass dominance to shrub dominance, but the mechanisms involved in this conversion process not completely understood. Aeolian processes likely contribute shrubland. The purpose of research is provide information regarding how vegetation changes occur an as a result aeolian sediment transport. experimental design included three treatment blocks, each with 25 × 50 m area where all grasses, semi-shrubs, and perennial forbs were hand removed,...
Abstract Novel carbon sequestration strategies such as large-scale land application of biochar may provide sustainable pathways to increase the terrestrial storage carbon. Biochar has a long residence time in soil and hence comprehensive studies are urgently needed quantify environmental impacts application. In particular, black emissions from soils amended with counteract negative emission potential due on air quality, climate, biogeochemical cycles. We investigated, using wind tunnel...
