Abstract Global biodiversity loss and ecosystem services are significantly impacted by vegetation stress environmental degradation. The study evaluates dynamics long-term meteorological variables in Amathole District Municipality, South Africa, using satellite-derived indices from 2001 to 2022. utilised Terra MODIS Landsat time series data evaluate cover variation the seasonal Vegetation Condition Index (VCI) Normalized Difference (NDVI). A MODIS-specific compositing algorithm was used acquire extract Application for Extracting Exploring Analysis Ready Samples (AppEEARS) area extent. Pearson correlation non-parametric trend analysis were assess characteristics influence of temperature, precipitation, potential evapotranspiration (ET o ) on cover. results reveal a significant decline (<10%) quality green condition index moderate low due prolonged dryness autumn winter, affecting VCI trends. In certain years, western region has experienced browning trends increased vegetation. Spring summer months high greenness (50-100%), with inter-annual decadal NDVI shifting, causing drought sensitivity east. found positive (P < 0.001) between precipitation simulated anomalies dynamics, contrasting changes primarily observed small areas, greening resulting an rate ET , which turn affects temperature change. approach is suitable semi-arid environments can be adopted stakeholders its geospatial implications monitoring evaluation.

Analysis and Prediction of Land Use/Land Cover Changes in Korgalzhyn District, Kazakhstan

Agronomy, Год журнала: 2024, Номер 14(2), С. 268 - 268

Опубликована: Янв. 25, 2024

Changes occurring because of human activity in protected natural places require constant monitoring land use (LU) structures. Therefore, Korgalzhyn District, which occupies part the State Natural Reserve territory, is considerable interest. The aim these studies was to analyze changes composition use/land cover (LULC) District from 2010 2021 and predict LU transformation by 2030 2050. Landsat image classification performed using Random Forest on Google Earth Engine. combined CA-ANN model used LULC 2050, were carried out MOLUSCE plugin. results showed that 2021, there a steady increase share ploughable an adequate reduction grassland. It established that, this trend will continue. At same time, be no drastic other classes. obtained can helpful for development management plans policies District.

Are we losing water storage capacity mostly due to climate change – Analysis of the landscape hydric potential in selected catchments in East-Central Europe

Ecological Indicators, Год журнала: 2023, Номер 154, С. 110913 - 110913

Опубликована: Сен. 10, 2023

Are we losing water mostly due to climate change? This study delves into that question. The main innovation of this research lies in developing a methodology forecasts future shifts resources through the use nondimensional indicators, such as Landscape Hydric Potential (LHP), caused by change scenarios, land and cover (LULC) projections, combination both factors. LHP method draws upon range indicators shape geosphere at catchment scale, namely: hydrogeological conditions, soil climatic geomorphological LULC. analysis was carried out for 33 catchments located Upper Vistula River Basin East-Central Europe. conducted following stages. First, values were calculated present conditions. Subsequently, an anticipated changes LULC near far future. Lastly, simulations performed project how might evolve, considering potential over time. results have shown under current mountainous are characterized higher than highlands or plains. Agricultural areas projected experience largest Climatic balance indicate minimal changes, irrespective time horizon. Our studies conclude predicted could more significant impact on change.

Regulation of Flood Dynamics by a Check Dam System in a Typical Ecological Construction Watershed on the Loess Plateau, China

Water, Год журнала: 2023, Номер 15(11), С. 2000 - 2000

Опубликована: Май 25, 2023

The check dam is the most important engineering measure in place for controlling water and preventing soil loss gully on Loess Plateau. This study assesses Jiuyuangou, a typical governance watershed of Plateau, studies influence that system has dynamics sub-storm floods over different return periods by coupling one-dimensional hydrodynamic MIKE 11 model with distributed hydrological SHE model. research demonstrates following: significantly reduces flood’s peak flow total volume basin also increases flood duration. former effects are greater than latter effect. peak’s rate reduction, volume’s reduction duration’s increase all linearly as number dams increase. Of systems, best linear response to reduction. runoff basin. After built, average decreases 54%. velocity reduced degrees value compared scenario lacking any kind dam. have impact shorter period, being 58.56% slower. Finally, intensity erosion middle lower reaches watershed, it changes distribution original channel runoff. These findings expected provide scientific basis guiding construction high-quality development In addition, basins can trap water, sediment nutrients, contribute ecosystem diversity maintaining imbalances around world.

Simulating Urban Agglomeration Expansion in Henan Province, China: An Analysis of Driving Mechanisms Using the FLUS Model with Considerations for Urban Interactions and Ecological Constraints

Land, Год журнала: 2023, Номер 12(6), С. 1189 - 1189

Опубликована: Июнь 6, 2023

Urban expansion is influenced by complex and variable social, economic, natural, policy-related factors. Given their nonlinear interactions, accurately modeling these urban processes poses a challenge. While most studies treat the city as an independent entity, prioritizing internal factors, land intercity interactions ecological environment. This study proposes new approach that couples gravitational field model, constraints, Future Land Use Simulation (FLUS) comprehensively considering impact of interaction The experiment in Henan Province China assessed effects factors such basic spatial variables (Slope distance to center), field, constraints on through optimal parameters-based geographical detector (OPGD) model. feasibility method was confirmed this case study, which shows it improves simulation accuracy agglomeration scale, particularly for central cities. We identified two important affecting agglomerations. Areas with stronger fields are more likely attract neighboring resources promote expansion, whereas constrain behavior cities under condition environmental resource protection needs, both them work together influence clusters. Therefore, we posit considerations future planning agglomerations coordinating harmonious development urbanization conservation.
