As an essential pathway for nature-based solutions, vegetation restoration can effectively absorb carbon sequestration and mitigate global warming. However, the excessive water consumption by expansion may create potential conflicts between natural ecosystems human systems, even exacerbate local shortages, especially in water-limited dryland regions. By evaluating availability using multiple datasets, this study explored allowable conversion China’s drylands under constraint of availability. We found that additional resources available were 2.7 ± 11 mm (median SD) from 2003 to 2018 but it decreased over period (-1.15 yr-1). 45.0% area had deficits, after considering existing consumption. Under current constraints, gross primary productivity (GPP) could be restored ranged 4% 7% depending on types (7.1% forests, 6.1% grasslands, 4.3% irrigated crops, 5.6% rain-fed crops). In surplus areas, primarily south east drylands, most conversions toward higher-water-consumption allowed occur. deficit west converting all less water-intensive would not compensate regions, suggesting have exceeded water-carrying capacity. Our research highlights importance provides guidance decision-making while ensuring sustainability.

Abstract Vegetation plays a crucial role in nature, with intricate interactions between it and the geographical environment. The Yangtze River Basin (YRB) refers to third largest river basin globally an essential ecological security barrier China. Monitoring vegetation dynamics is of profound significance for addressing climate change, soil erosion, biodiversity loss basin's ecosystems. Here, we investigate spatiotemporal variations at both land cover scales YRB from 2000 2020. We elucidate determinants driving changes explore future normalized difference index (NDVI) trends. results indicate that NDVI increased rate 0.0032 year −1 ( p < 0.01) over past 21 years, anticipated maintain upward trend future. Regions upper middle reaches demonstrated higher NDVI, whereas regions headwater area lower showed NDVI. Significant improvement was primarily concentrated central part basin, while noticeable degradation observed eastern region. Temperature wind speed were identified as primary controlling factors affecting greenness. Global‐scale oscillations played significant periodic La Niña events tending increase El Niño hindered its rise. Land types influenced by long‐term natural human activities, although short‐term might be more affected latter. Our findings provide valuable insights into mechanisms behind variability driven multiple variables, strong carbon sink capacity advances conservation development

Revealing the relationship between land use changes and soil erosion provides a reference for formulating future strategies. This study simulated historical based on RULSE GeoSOS-FLUS models used random forest model to explain relative importance of natural anthropogenic factors erosion. The main conclusions are as follows: (1) From 1990 2020, significant in occurred Kunming, with continuous reduction woodland, grassland, cropland, being converted into construction land, which grew by 195.18% compared 1990. (2) During this period, modulus decreased from 133.85 t/(km²·a) 130.32 loss 74,485.46 t/a, mainly due conversion cropland ecological lands (woodland, grassland). (3) expansion will continue, it is expected that 2050, decrease 3.77 t/(km²·a), 4.27 3.27 under development, rapid protection scenarios, respectively. However, scenario, increased 0.26 2020. (4) spatial pattern influenced both factors, human activities intensify future, influence further increase. Traditionally, thought increase loss. Our may offer new perspective provide planning management Kunming.

Soil management has a direct impact on its physical properties and crop productivity. In the case of pitahaya (Hylocereus spp.), mulch could be essential for conserving soil moisture structure. This study analyzed how in cultivation affects at different particle sizes (sand, silt, clay). Two plots were evaluated: one with other traditional management, assessing moisture, bulk density, size depths. Statistical analysis was performed using ANOVA Tukey test 5%. The results revealed that soils managed showed higher surface layer (0–5 cm) lower density compared to unmulched soils. suggests reduces evaporation helps improve Mulch is suggested as strategy optimize quality crops, thus promoting productivity sustainability.

Abstract The Ili River Delta (IRD) is an ecological security barrier for the Lake Balkhash and important water conservation area in Central Asia. In this study, we selected IRD as a typical research area, simulated yield from 1975 to 2020 using module of Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. We further analyzed temporal spatial variations 2020, investigated main driving factors (precipitation, potential evapotranspiration, land use/land cover change, inflow River) variation based on linear regression, piecewise Pearson’s correlation coefficient analyses. results indicated that showed decreasing trend, distribution pattern was “high east low west”; overall, all use types decreased slightly. volume grassland most reduced, although increased owing River. At same time, has led expansion wetland areas, improvement vegetation growth, increase regional thus resulting overall reduction conservation. depth precipitation had similar patterns; change climate reason decline function delta. reservoir upper reaches regulated runoff into Balkhash, promoted restoration, positive effect conservation; however, cannot offset negative enhanced evapotranspiration. These provide reference rational allocation resources ecosystem protection IRD.

The annual varied from few‐ton/hectare/year to 1630.5. high erosion susceptibility was prevalent elevated area low severity seen low‐lying plains middle lower reaches. maximum export (430.16‐ton/hectare/year) noticed hills Vindhyans, Bundelkhand, Deccan traps. Contrary this transport observed flat alluvium plains. conservation practices slightly more effective KRB. Its crop cover reduces impact rain's kinetic energy, increase recharge, mitigates erosion. These research output may be helpful planners minimizing enhancing agricultural productivity.

Rapid urbanization and climate change exacerbate soil erosion globally, threatening ecosystem services sustainable development. However, current predictive studies on future often lack comprehensive consideration of the interactions between land use change. This study proposed a scenario analysis framework that integrated four Shared Socioeconomic Pathways (SSPs) from CMIP6 with bespoke land-use scenarios (Inertial Development (IDS), Urban Priority (UDPS), Ecological Protection (EPPS), Farmland (FPPS)) to create 16 scenarios, allowing for more nuanced understanding potential trajectories. The results indicated (1) compared baseline period (2000-2020), in Central Yunnan Agglomeration (CYUA) would improve, albeit significant differences among scenarios. most notable improvement was under EPPS + SSP1-2.6 (ScC1). (2) lower Jinsha, upper Nanpan, Red river basins were high-risk areas CYUA, each dominated by different factors, necessitating differentiated control measures. (3) Land-use jointly influenced direction development, lightest occurring heaviest FPPS. largest decrease occurs SSP1-2.6, whereas smallest SSP5-8.5. (4) Climate had impact than change, reduction rates modulus area relative past 20 years being 9% 3.77%, respectively, approximately eight times magnitude recommends reducing carbon emissions, enhancing vegetation cover, controlling slope development effectively mitigate risk CYUA promote regional method provides new insights into global small-scale predictions.
