Public–private partnerships as catalysts for green infrastructure: a three-pronged analysis of economic, environmental, and institutional factors

Frontiers in Sustainable Cities, Journal Year: 2025, Volume and Issue: 7

Published: May 6, 2025

As cities contend with the escalating challenges of climate change, rapid urbanization, and resource depletion, need for sustainable infrastructure solutions has never been more urgent. Cities account 75% global CO 2 emissions, yet efforts to implement green remain fragmented. Green public–private partnerships (PPPs) offer a solution, but mechanisms effectively leveraging these collaborations underexplored. Despite growing interest in PPPs, critical knowledge gap persists: how is PPP leveraged tackling crucial urban advancing infrastructure? This study critically examines PPPs drive progress six key sectors: renewable energy, mobility, water management, waste building greening. Through qualitative case studies, analyses flagship projects from both developed developing countries. The presents that will thrive when backed by strong institutional frameworks, long-term financial commitments, adaptive collaborative environments. futures lies not just government action strategic PPPs. makes call rethink partnerships—aligning private sector innovation public mandates. It offers actionable insights policymakers, planners, investors, demonstrating are catalysts sustainability if scaled effectively, they could redefine trajectory development.

Evaluating Nature-Positive Urban Renewal Green Infrastructure Projects in Addis Ababa: A Multi-Dimensional Approach Using the Urban Nature Futures Framework

Urban Science, Journal Year: 2025, Volume and Issue: 9(5), P. 161 - 161

Published: May 9, 2025

Rapid urbanization in the Global South poses challenges to ecological integrity, cultural heritage, and equitable access green infrastructure. This study evaluates effectiveness of recent infrastructure projects Addis Ababa, Ethiopia, including flagship parks upgraded road corridors, through lens Urban Nature Futures Framework (UNFF). To operationalize UNFF’s three perspectives—Nature for (NN), Society (NS), as Culture (NC)—a context-specific set indicators was developed existing literature, global assessment frameworks, stakeholder consultations. A mixed-methods approach, combining structured surveys with both qualitative quantitative thematic analysis, applied across four groups: residents, park visitors, corridor users, experts. The results indicate that while social benefits (NS) are widely recognized, (NN) (NC) dimensions receive comparatively less emphasis. Regression analysis shows education, employment, space use frequency significantly shape perceptions NS NC, NN more consistently shared groups. demonstrates practical value UNFF an tool offers a replicable methodology evaluating multifunctional findings underscore need inclusive, biodiversity-positive, culturally grounded urban renewal strategies. These insights relevant planners policymakers aiming foster resilient environments rapidly growing cities.

Constructing a Future Green Space Ecological Network Based on Multi-Scenario Urban Expansion: A Case Study of Chengdu, Sichuan, China

Forests, Journal Year: 2024, Volume and Issue: 15(10), P. 1818 - 1818

Published: Oct. 17, 2024

As urban spaces expand, changes in land use significantly affect the structure and function of ecosystems, particularly with challenges such as green space reduction uneven distribution. This study focused on central area Chengdu, China, simulating forecasting various development scenarios for 2035, including cultivated protection (CP), economic (ED), ecological priority (EP), natural (ND). The construction networks followed a systematic process, incorporating key methods source identification, landscape resistance surface construction, corridor extraction. connectivity these was assessed using syntax. results indicated that: (1) Construction expanded across all scenarios, ED scenario having largest area, while EP resulted significant increase space. (2) Ecological corridors were established under every scenario, featuring most extensive well-connected network, linking patches surrounding areas. (3) scenario’s network displayed integration, choice, connectivity, depth values that indicate complete stable structure. provides comprehensive analysis different strategies, offering valuable insights optimizing planning management.

Mitigating Urban Heat Islands: The Role of Green Building Strategies

International Journal of Environment and Climate Change, Journal Year: 2024, Volume and Issue: 14(12), P. 647 - 662

Published: Dec. 28, 2024

The combined effects of local warming brought on by urbanisation and global climate change are making urban heat a growing problem for many cities. Urban heat-related issues must be addressed immediately because these phenomena have substantial negative the environment, economy, society, human health. Although buildings play significant role in heat, they also offer opportunities mitigation through decarbonisation built environment. building industry has acknowledged green (GBs) as an innovative philosophy practice. GBs been suggested way to reduce islands (UHI) other issues. purpose this study is identify most important architectural factors that effectively UHI. Using extensive literature review methodology, identified eighteen references following thorough screening more than 1400 preliminary studies. These sources concentrate ways mitigate different approaches, such cutting carbon emissions, lessening artificial landscapes, enhancing energy efficiency. findings indicate significantly contribute reducing lowering minimising promoting energy-efficient designs. This provides holistic analysis mitigation, aiming inform future research planning development. manuscript addresses critical topic scientific community. It highlights mitigating Heat Island effect, which essential combating change. useful insights identifies key strategies, roofs infrastructure. valuable researchers, policymakers, practitioners development resilience.
