Heilongjiang Province, a major grain-producing region in China, faces ecological vulnerabilities that directly affect its sustainable development. A scientific assessment of the spatiotemporal characteristics vulnerability and influencing factors is crucial for deeper understanding environmental issues provides theoretical support enhancing regional governance capabilities. The SRP model, combined with AHP-CRITIC weighting method, was employed to assess Province’s vulnerability’s temporal differentiation trends between 2000 2020. aggregation kinds were examined using spatial autocorrelation. GeoDetector used determine main elements affecting province. Additionally, status 2030 predicted CA-Markov model. findings indicate (1) average EVI values Province during three periods 0.323, 0.317, 0.347, respectively, indicating medium level across province; initially decreased then worsened. Spatially, distribution followed pattern “high east west, low north south”. (2) Spatial agglomeration evident, high-high (H-H) primarily occurring heavily extremely vulnerable areas characterized by high human activity, while low–low (L-L) mainly found mildly marginally favorable natural background. (3) Biological abundance, net primary productivity, dry degree, PM2.5 drivers vulnerability, interactions these amplifying their impact on vulnerability. (4) model prediction results indicated an upward trend overall 2030, reflecting decline environment. study indicates closely linked geographic conditions influenced through interplay several elements. Based zoning results, this paper proposes recommendations regions different levels, aiming provide future restoration

Ecological vulnerability and driving factors in the himalayan transboundary landscape under global climate change

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

Published: Feb. 10, 2025

Climate change and human activities are placing significant pressure on the carrying capacity of Himalayan alpine ecosystem. This study focuses seven transboundary protected areas national parks in Himalayas, including China's Everest National Nature Reserve Nepal's Sagarmatha Park, Manaslu Conservation Area, Langtang Gauri Sankar Makalu Barun Kanchenjunga Area. We used Vulnerability Scoping Diagram (VSD) model to assess ecological vulnerability, analyzing land use changes landscape patterns from 2000 2020 identify key drivers changes. The fragmentation landscapes initially increased then decreased, with values 4.05, 3.99, 3.86 observed, indicating a general reduction regional vulnerability. south slope demonstrated lower vulnerability than north slope. Key factors influencing patch density included annual average temperature, population density, precipitation. Annual precipitation, normalized vegetation index were primary largest index. shape was most affected by index, slope, while spread primarily influenced precipitation homogeneity strongly related water provides representative case for cooperation conservation, offering insights into sustainable development strategies cross-border regions Himalayas.

Assessing forest villagers’ livelihood vulnerability to the environmental changes in Buxa Tiger Reserve of sub-Himalayan India

Trees Forests and People, Journal Year: 2024, Volume and Issue: 17, P. 100632 - 100632

Published: July 21, 2024

The Himalayan forest communities historically lived in harmony with their environment; however, anthropogenic activities have disrupted this balance. Deforestation, climate change, and habitat degradation heightened vulnerability, compounded by human-wildlife conflicts (HWCs) limited access to crucial livelihood capitals. Addressing these challenges requires a deeper understanding of factors associated household-level prompting study the Buxa Tiger Reserve sub-Himalayan India. Data from 345 households across ten villages reveal significant exposure HWCs, particularly elephant crop raiding leopard-induced livestock losses. Sensitivity arises water scarcity, health issues, food shortages, inadequate housing conditions, while adaptive capacity stems infrastructural financial constraints, among others. Spatial disparities emerge, tribal exhibiting lower but lesser compared non-tribal communities. Proximity different facilities (e.g., markets, institutions, primary healthcare centers) government schemes significantly influence revealing unexpected associations. Besides, villagers' willingness relocate demonstrates higher perceived benefits outside reserve. By unraveling layers vulnerability at household level, provides valuable guidance for policymakers, managers, other stakeholders. It offers insights into sustainable development strategies, resonating globally harmonize human actions environmental conservation.
