Spatiotemporal Dynamics of Urban Green Spaces and Climatic Vulnerability of Togolese Cities in the Context of Rapid Urbanisation: The Case of Lome and Kara

Land, Journal Year: 2025, Volume and Issue: 14(3), P. 471 - 471

Published: Feb. 25, 2025

In Togo, the cities of Lomé and Kara are undergoing rapid urbanisation driven by strong population growth expansion urban built-up areas, leading to significant reductions in green spaces (UGSs). UGSs vital for climate regulation human well-being mitigating heat, improving air quality, supporting mental health. This directly replaces vegetated areas with impervious surfaces, diminishing UGS their associated ecosystem services. Consequently, climatic vulnerability has increased, highlighting need sustainable development conservation. study examines spatiotemporal dynamics using Landsat imagery from 1988, 2000, 2012, 2022, applying a supervised image classification approach maximum likelihood algorithm. Post-classification change detection quantified loss. Additionally, models 2060, 2100 were developed Shared Socioeconomic Pathways (SSP 2.45 SSP 5.85) multifactorial modelling approach. The results reveal decline 85.98% 40.78% 93.99% 36.68% between 1988 primarily due urbanisation. Vulnerable zones, currently UGSs, risk disappearance 2060–2100, exacerbating risks.

Major public health events pose a huge challenge to the sustainable improvement of city dwellers’ ecological well-being, hindering achievement urban construction goals. In context resilient and all-aged friendly construction, age factor is given special consideration in green space management meet heterogeneous demands preferences dwellers for benefit. However, young, middle-age elderly utilization spaces during different periods pandemic are poorly known. Meanwhile, insufficient discussion on differences well-being contributions types has led difficulties effectively connecting planning with well-being. To help fill this gap, study utilizes field data landscape greening Beijing from 2019 2023 analyze evolution behaviors among group dwellers. Furthermore, applies ordinary least square regression model (OLS) explore impact various The results revealed significant effects 2019–2023.

Identifying the Response of Ecological Well–Being to Ecosystem Services of Urban Green Space Using the Coupling Coordination Degree Model: A Case Study of Beijing, China, 2015–2023

Forests, Journal Year: 2024, Volume and Issue: 15(9), P. 1494 - 1494

Published: Aug. 26, 2024

Understanding the response of ecological well–being to ecosystem services urban green space is imperative for conservation and management. However, few studies have focused on process spatial relationship in mega cities, while residents’ demand evaluation not been fully considered. In this study, index system was developed through integrating subjective objective indicators. Using main area Beijing as an example, our results indicate that from 2015 2023, has continuously increasing. Moreover, study indicated coupling coordination degree between still need be improved. addition, three modes were identified study: high area, moderate low area.

Balancing Environmental and Human Needs: Geographic Information System-Based Analytical Hierarchy Process Land Suitability Planning for Emerging Urban Areas in Bni Bouayach Amid Urban Transformation

Sustainability, Journal Year: 2024, Volume and Issue: 16(15), P. 6497 - 6497

Published: July 30, 2024

Urbanization in Bni Bouayach, Morocco, threatens vital irrigated areas and agricultural land, raising concerns about environmental sustainability. This study employs a GIS-based Analytical Hierarchy Process (GIS-AHP) framework to assess land suitability for sustainable development. It addresses knowledge gaps urban planning as follows: (i) Evaluating development: this analysis identifies appropriate expansion while minimizing impact. (ii) Balancing human needs: the integrates ten criteria encompassing accessibility, economic, social, geomorphological, factors. comprehensive approach results Land Suitability Map with five categories: prohibited/unfit, extremely unsuitable, moderately adequately suitable, highly suitable. Notably, 39.5% of area falls within suitable or categories, primarily consisting accessible bare lands pastures. These findings provide valuable insights policymakers guide Bouayach towards development, ensuring balanced growth that respects both preservation resident needs.

Spatio-Temporal Analysis of Green Infrastructure along the Urban-Rural Gradient of the Cities of Bujumbura, Kinshasa and Lubumbashi

Land, Journal Year: 2024, Volume and Issue: 13(9), P. 1467 - 1467

Published: Sept. 10, 2024

This study analyses the dynamics of green infrastructure (GI) in cities Bujumbura, Kinshasa, and Lubumbashi. A remote sensing approach, combined with landscape ecology metrics, characterized this analysis, which was based on three Landsat images acquired 2000, 2013, 2022 for each city. Spatial pattern indices reveal that GI suppressed Bujumbura contrast to Lubumbashi, exhibited fragmentation. Furthermore, values stability, aggregation, fractal dimension metrics suggest experienced rather intense a reduction continuity its GI, while Kinshasa showed weaker tendencies towards patch aggregation during period. In contrast, Lubumbashi strong within context significant anthropization. The evolution Normalized Difference Vegetation Index demonstrates sawtooth tall vegetation patches compared gradual decrease It is recommended urban growth these should be carefully planned ensure integration sufficient GI.
