Abstract Urban green spaces serve as critical infrastructure for sustainable cities, yet their strategic implementation remains challenging, particularly in developing regions. This study develops a spatial decision support framework optimal space allocation Mzuzu City, Malawi, employing an integrated approach of Geographic Information Systems (GIS), Multi-Criteria Analysis, and Analytical Hierarchy Process. Eight environmental socio-spatial parameters were analysed: population density, road network proximity, topographic gradient, elevation, vegetation indices, land use patterns, hydrological features, nitrogen dioxide concentrations. The results indicate that the area's 6.97% (1,099.65 ha) demonstrates high suitability interventions, while 26.48% (4,178.68 is deemed unsuitable. Population density emerged primary determinant, with weight coefficient 0.379. Spatial analysis revealed concentrated zones Mchengautuwa West, central-western Nkholongo/Lupaso, Masasa East, eastern Kaning'ina, contrasting limited opportunities Zolozolo East Msongwe. research provides replicable methodology evidence-based urban greening initiatives sub-Saharan African contributing to equitable planning development.

Green spaces such as forests, grasslands, and croplands (including gardens) can be found in urban environments. Although they benefit human animal well-being, have become threatened due to rapid growth unplanned development. Yet, little attention has been given studying the dynamics of green sub-Saharan Africa. In this study, we examined land use cover (LULC) change fragmentation (especially, spaces) within second fastest urbanising city Ghana, Tamale. particular, focused our analyses on its core (∼5 km radius around centre) relevance economy society. Landsat data was used estimate metrics past future LULC changes study area from 1990 2052. We clear patterns space decline core: i.e., became patchy over time pattern expected continue future. Additionally, built-up class benefited with latter being significantly negatively correlated population size. Our investigation reveals that protected forests tree plantations contributed a significant proportion available core. However, these areas were becoming increasingly by forest reserve downsizing, indiscriminate activities (e.g., logging encroachment), sale public lands private developers, practices commonly associated growth. Hence, enforcement relevant local legislations 2016 Land Use Spatial Planning Act [Act 925]) coupled integration initiatives policies encourage are needed ensure sustainability ecosystems for well-being humans environment.

The evaluation and analysis of the ecological vulnerability urban green-space systems are conducive to sustainable development systems. Taking system in Beijing–Tianjin–Hebei region 2010, 2015, 2020 as research object, an ESSR model was first constructed, a total ten types impact factors were integrated into four dimensions “Exposure, Sensitivity, State Response”. weight objectively determined via spatial principal component analysis, evaluated superposition analysis; evaluation’s results graded. Moreover, transfer matrix, center-of-gravity migration model, standard deviation ellipse, autocorrelation used study temporal variation characteristics results; then, driving force analyzed based on geographical detector. Finally, rationality verified using changing trend remote sensing index (RSEI). show that has decreased year by for past years. distribution law “Hebei surrounds Beijing Tianjin” is presented this space, 2015 mutation node. In moderately severely vulnerable areas Hebei surrounded mildly Tianjin. 2020, Vulnerability expands slightly east–west direction shrinks north–south direction, center gravity shifts towards along northeast direction. shows significant positive autocorrelations exhibits very obvious agglomeration. addition, result combined effect various factors, education degree, human disturbance index, annual average precipitation dominant factors. provide reference effective application functions.

Abstract. Today, city planners design urban futures by considering environmental degradation and climate mitigation. Here, we studied the greenhouse gas fluxes of lawns meadows linked observations with plant functional types soil properties. In eight in Helsinki metropolitan area, Finland, carbon dioxide (CO2), methane (CH4) nitrous oxide (N2O) were measured using manual chambers, recorded. Four these sites, i.e. an irrigated lawn, old mesic meadow, a non-irrigated lawn young dry more intensively 2021–2022. The process-based ecosystem model JSBACH was utilized together momentary collected approximately every second week on CO2 exchange to quantify annual (C) balance sites. On remaining initial dynamics conversion from transforming parts late 2020 conducting measurements 2022. mean photosynthetic production (GPP) meadow highest this study, whereas had lowest GPP. stronger C sinks compared meadows. However, net values uncertain as soils not equilibrium vegetation at all which is common for habitats, modelling heterotrophic emissions therefore challenging. did affect CH4 N2O. Moreover, resistant drought events than lawn. Lastly, proportion herbaceous flowering plants other grasses higher lawns. Even though social economic aspects also steer development, results can guide planning when environmentally friendlier green spaces smartness.
