Developing an Integrated Risk Assessment Method for Ecological Protection Redlines to Optimize Ecological Protection Policies: Based on a Multidimensional Assessment Framework and Risk Path Analysis

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

ABSTRACT As urbanization and industrialization advance, China faces increasingly severe ecological challenges. The Ecological Protection Redline (EPR) policy is a crucial tool for land use management protection but requires comprehensive risk assessment method to address ongoing This study integrated multiple factors with resilience theory establish “Hazard‐Exposure‐Vulnerability‐Damage‐Final Risk” framework, assessing the spatiotemporal dynamics risks of different EPR types in Qinghai Province over 20 years. Path analysis was further used reveal relationships between stages. Results show increasing hazards exposure Water Conservation (WC), Biodiversity Maintenance (BM) Land Desertification (LD) types, improved water conservation, stable biodiversity, controlled desertification vulnerability across regions. Integrated results downward trend WC type, BM type fluctuated improved, an initial increase followed by decrease LD type. revealed that damage WC‐type driven direct hazard impacts, BM‐type vulnerability, LD‐type indirect effects through exposure. emphasizes optimization policies reducing external disturbances enhancing ecosystem resilience, providing recommendations practical experience sustainable management.

Spatiotemporal Evolution Characteristics and Prediction of Habitat Quality Changes in the Poyang Lake Region, China

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3708 - 3708

Published: April 19, 2025

The terrestrial spatial patterns were affected by human activities, primarily on regional land use (LU) changes, with habitat quality (HQ) serving as a prerequisite for achieving sustainable development. Assessing and predicting the spatiotemporal evolution characteristics of LU changes HQ is critical formulating strategies enhancing ecosystem service functions. Using Poyang Lake Region our research object, this employs data utilizes ‘InVEST’ model hot-spot analysis to quantitatively evaluate in during 2000–2020. PLUS then applied predict trends from 2020 2050. findings are follows: (1). From 2000 2020, areas forestland, shrubland, sparse woodland, paddy fields, dryland showed decreasing trend, reductions mainly occurring urban expansion zones such Nanchang City largely converted into construction land. (2). Since 2000, has shown slight retrogressive evolution, significant heterogeneity. spatially exhibits pattern improvement radiating outward major cities. (3). Predictions 2030 2050 indicate that will continue decline, most downward built-up their peripheries. reveal an ring around east–west corridor linking Pingxiang, Yichun, Xinyu, Nanchang, Fuzhou, Yingtan, Shangrao. This study provided basis direction planning policies its surrounding areas, while also contributing agrarian security enhancement levels region.

Anthropogenic activities accelerate LULC conversion and only a sustainable development scenario is optimal for agro-pastoral ecotone development

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 23, 2025

Despite the ecological and socioeconomic importance of agro-pastoral ecotones, changes in land use cover (LULC) their driving mechanisms are not comprehensively understood. In this study, a systematic framework for LULC assessment covering comprehensive timeframes was constructed Tabu watershed. Results demonstrated that new process began 1998, with significant increase farmland decrease grassland. The dynamic degrees structural variation coefficients indicated intensive frequent LULC. Conversion ratios between grassland exceeded 95%, construction encroached upon Grassland were driven mainly by natural factors based on random forest regression, as well land. influence anthropogenic drivers became significant. Under sustainable development scenario, high fractional vegetation 2034 most significant, area bare decreased, steadily increased, reduction under control. both ecosystem stability can be achieved. This study provides insights into regional dynamics guidance management.

Mapping Human Pressure for Nature Conservation: A Review

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(20), P. 3866 - 3866

Published: Oct. 18, 2024

The escalating human pressures on natural ecosystems necessitate urgent and effective conservation strategies to safeguard biodiversity ecosystem functions. This review explored current techniques for mapping pressure, with a particular focus their application in nature conservation, especially within protected areas (PAs). Specifically, we analyzed the impacts of seven major types PAs. Additionally, discussed four key methods including land use intensity, footprint, digital other proxies, examining distinct characteristics respective advantages disadvantages. our research pressure assessing its suitability applications delineating directions future work. These insights contributed better support management
