This study focuses on Kaptembwa, Nakuru, Kenya, to address gaps in understanding these risks and explore the potential of Nature-based Solutions (NbS) in fostering equitable urban development. Using a six-step reiterative participatory approach, the study identifies localised risks such as heat stress, flooding, and safety, revealing their disproportionate impacts on groups, such as women, children, and market vendors. Findings emphasise the importance of integrating resident perspectives into planning processes to ensure that NbS address community-specific needs while delivering social, economic, and environmental benefits. Stakeholder workshops demonstrated the value of cross-sectoral collaboration, producing multi-functional solutions that also align with community priorities for economic development. However, systemic challenges—including resource constraints, informal governance structures, and inequities in engagement—underscore the need for transformative, inclusive urban planning. While the participatory process enhanced local capacity and knowledge of participants, it also highlighted gaps in critical expertise and time constraints that require attention in future initiatives. By bridging critical knowledge gaps, this study offers insights into addressing slum-specific vulnerabilities and advancing equitable NbS planning in low- and middle-income countries. The study emphasises the need for multi-functional land use and collaborative approaches to urban development.

Conducted in Tehran, Iran, this study surveyed 415 urban forest visitors using a structured questionnaire and applied structural equation modeling to test the proposed relationships. The findings indicate that all three dimensions of media literacy significantly enhance environmental attitudes, responsibility, and concern, which, in turn, strongly predict pro-environmental behavior. Specifically, media access increases exposure to ecological information, while critical content analysis and engagement foster a deeper understanding and commitment to environmental issues. These results highlight the critical role of media literacy as an indirect driver of pro-environmental behavior, suggesting that informed media engagement can cultivate a more ecologically conscious and proactive public. The study offers theoretical implications for integrating media literacy into behavioral frameworks for urban forest visitors, expanding its relevance within environmental psychology.

The research employs a two-pronged methodology. First, a systematic review of 84 research articles published between 2010 and early 2024, encompassing simulations, experiments, and case studies, reveals a wide range of reported energy savings from hybrid ventilation, underscoring the need for standardized performance comparisons. Building upon this foundation, the second phase employs a detailed case study. Using EnergyPlus software, a dynamic energy model of a Dubai office building was created and validated against a year’s worth of actual energy consumption data. This validated model was then modified to simulate implementing a hybrid ventilation system, directly addressing the performance variations highlighted in the literature review. Results demonstrate that the hybrid system can achieve a 23% annual reduction in energy consumption compared to a conventional system, with savings more pronounced during cooler seasons (29%) than in hotter months (13%). Furthermore, the system yielded a 20% reduction in carbon emissions.
