Ecological security patterns (ESPs) provide an effective spatial approach for identifying critical conservation areas and ensuring regional ecological security. However, prior research has not paid much attention to the importance of stability sources in time-series changes, which is especially maintaining functions ecologically fragile areas. Focusing on Ningxia Hui Autonomous Region (NHAR) China, this study evaluated spatiotemporal change ecosystem services (ESI) from 2000 2020, integrating principal component analysis (SPCA) circuit theory propose a novel ESP construction framework that aims address issue insufficient consideration source stability. A total 93 stable were identified, with capacity ensure continuous provision high-level resistance external disturbances. The extraction 234 corridors 430 nodes effectively enhanced flow processes connectivity. ESP, constituted by above elements, can serve as core space basic skeleton maintain sustainable landscape. This provides scientific references key priority formulating targeted restoration strategies

Mapping multigroup responses to land cover legacy for urban biodiversity conservation

Biological Conservation, Journal Year: 2024, Volume and Issue: 291, P. 110508 - 110508

Published: Feb. 20, 2024

Urban biodiversity plays a crucial role in the functioning of urban ecosystems and significantly impacts well-being quality life for city residents. By focusing on Porto as case study, influence local-scale land cover evolution is investigated, using species richness birds, reptiles, amphibians indicators, within multimodel inference framework. The results underscore importance past legacy shaping biodiversity. Birds, respond positively to older vegetation patches but negatively long-established areas. Birds exhibit adaptability by responding recent vegetation, while tend avoid newly vegetated zones. fragmented distribution reptiles suggests limited mobility potential delayed response habitat loss isolation. Reptiles benefit from both wooded herbaceous habitats, emphasizing local spatial diversity, water elements are critical amphibians, although many aquatic habitats context may not be suitable. Modeling guide identification priority areas conservation Porto, informing decision-makers, planners, conservationists. This spatially explicit research aids efforts create more ecologically resilient biodiverse environments. It highlights historical unique responses different vertebrate groups urbanization, contributing our understanding dynamics sustainable development.

Multi-Tier Land Use and Land Cover Mapping Framework and Its Application in Urbanization Analysis in Three African Countries

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(14), P. 2677 - 2677

Published: July 22, 2024

The population of Africa is expected to rise 2.5 billion by 2050, with more than 80% this increase concentrated in cities. Africa’s anticipated growth has serious implications for urban resource utilization and management, necessitating multi-level monitoring efforts that can inform planning decision-making. Commonly, broad extent (e.g., country level) change analyses only examine a homogenous “developed” or “built-up” area, which may not capture patterns influenced the heterogeneity landscape features within areas. Contrarily, studies examining at finer resolution are typically limited spatial single city level). goal study was develop test hierarchical integrated mapping framework using globally available Earth Observation data Landsat, Sentinel-2, Sentinel-1, nightlight imagery) accessible methodologies produce national-level land use (LU) urban-level cover (LC) map products support range global local initiatives. We our multi-tier methodology across three rapidly urbanizing African countries 2016–2020 period: Ethiopia, Nigeria, South Africa. initial output includes annual national maps (Tier 1) purpose delineating dynamic boundaries individual areas LU change. To complement Tier 1 maps, we detailed through LC classifications 2) delineated maps. Based on country-optimized sets selected leverage spatial/texture temporal dimensions data, obtained an overall accuracy between 65 60 2 dependent evaluation country, although consistent performance years providing solid foundation changes. demonstrate potential applications various analyses, including urbanization-driven change, countries. While findings allude general differences scales, further needed better understand complex drivers behind configurations their different countries, sizes, rates urbanization.
