Under the conditions of climate warming, grassland degradation, frequent sandstorms, and fast increases in livestock numbers, coordinating animal husbandry ecological protection is an important issue facing Mongolia. Using Khutag-Undur as example, this study explores dynamic process, future scenarios, optimization strategies system a typical Soum Mongolia from 2015 to 2050 under three socioeconomic scenarios CMIP 6: SSP1-RCP2.6, SSP2-RCP4.5, SSP5-RCP8.5. First, was deconstructed into subsystems: primary production, secondary herder consumption. Based on negative feedback mechanism forage-livestock balance, dynamics model for developed. This integrates spatial data such land cover NPP, well statistical livestock, income expenditures, sample plot surveys, questionnaires. The used simulate historical changes (2015–2022) forage production carrying capacity, stock, output Khutag-Undur, then forecast those variables 2022–2050. Second, most suitable scenario identified by comparing using pastural sustainability evaluation method. Finally, based indicators two-step reduction strategy proposed. main conclusions are that rapid growth numbers places considerable pressure grassland, SSP1-RCP2.6 Soum. However, even scenario, overloading remains evident. continuous implementation recommended maintain sustainable development conservation.

Many people believe that animal agriculture should be phased out and replaced with vegetarian substitutes. The livestock industry has also been attacked because it uses vast amounts of land. People forget grazing cattle or sheep can raised on land is either too arid rough for raising crops.

Fractional vegetation cover (FVC) and aboveground biomass (AGB) are critically important for monitoring grassland degradation, their accurate estimation can be used as key proxies assessing land degradation. The main purpose of this study was to estimate the FVC AGB in eastern Mongolian steppe using remote sensing machine learning. In context, spectral bands indices were extracted from processed Sentinel-2 data predictors. field derived pasture-monitoring database, which consisted 256 plots with measurements. Consequently, we imagery measurements vast a reference random forest (RF) models (R2FVC = 0.81, R²AGB 0.76). Among variables, predictor variables soil indices, especially NDVI, Simple Ratio (SR), OSAVI, highly predicting AGB. As expected, comparison among map values showed that spatial distribution consistent landscapes ecoregions area. maps only current condition cover, also analysed NDVI trends explain changes. We tested temporal Landsat time series Mann-Kendall trend test. This revealed 7.3% area, significantly increased, whereas significant decrease observed 58%

The grassland ecosystems of Mongolia are among the most sensitive to global climate change because arid and semiarid climate. As a key source primary productivity for livestock, quantification carrying capacity in winter early spring period is crucial sustainable livestock management livelihoods herders Mongolia. In this study, we used remote sensing data ancillary propose framework estimate aboveground biomass(AGB) (GCC) using Google Earth Engine (GEE) environment. We analysed spatial temporal changes GCC winter-spring during 2000–2020, status index (GCSIW) was proposed reflect utilization over past 21 years.

Abstract Aims The general effects of grazing by large herbivores on plant species composition and productivity are well known. Meanwhile, how different livestock affect community structure is not fully understood. In northern China, changing rapidly hence, it imperative to understand the resulting grassland composition. Location Xilingol, Inner Mongolia, China. Methods We studied three major affects typical steppe dominated Leymus chinensis , Stipa grandis Cleistogenes squarrosa Carex korshinskyi in a 4‐year field experiment using random block‐design with four treatments (sheep, goat, cattle, no grazing), under summer at moderate intensity. calculated above‐ground net primary (ANPP) selectivity index (SI) based biomass quantify forage preferences. Result found that (i) sheep preferred mixed subordinate species, cattle goat . (ii) Consistent these preferences, increased relative but reduced ; species; goats species. (iii) Overall, significantly ANPP, mainly due an increase ANPP cost Conclusions Summer intensity can while preferences drive divergent changes Our results also imply be used as mean manage vegetation dynamics.

Abstract In an era marked by accelerating climate change, habitat loss, and shifting land use patterns, it is crucial to understand the intricate effects of multiple stressors on ecosystems. This long‐term study sheds light complex interplay between grazing characteristics pasture dynamics offers insights into how various affect ecosystems facing environmental challenges. Our experimental documents that manipulation in restricting reindeer trampling through fencing led higher ground‐lichen biomass, volume, height (particularly one habitat), cover compared with open‐control plots. The effect varied depending habitat, for lichen height, lowest values were observed windswept exposed ridges mountain heaths (exposed/mountain), highest forested leeward‐heath (forest/leeward) habitat. average (past five years) number per square kilometer had indirect across habitats. We negative density dependence open plots exposed/mountain Fencing reduced this effect, which was also valid biomass except did not density.

Anthropogenic activities, such as grazing and fencing, have been known to alter the productivity biodiversity of grassland ecosystems, potentially affecting their functioning. However, impact these activities on aboveground biomass (AGB) plant diversity in alpine grasslands at different altitudes, well how they may be affected by soil nutrients environmental climate, is not understood. To address this knowledge gap, a study was conducted Lhasa Valley Tibet. In 2013, twelve metal fences were set up mountainous transects, field surveys paired sites early August 2021. The results showed that AGB slightly higher fenced compared grazed altitudes from 4000 5100 m, but decreased with altitude slower rate sites. Plant indices exhibited unimodal pattern increasing altitude, no significant differences between Soil climate found positively correlated both Multiple linear regression models revealed Shannon index largely influenced (AP AN) rather than growing season temperature sites, while more impacted These findings provide important insights into impacts fencing above-ground environments.
