Abstract
When redeveloping crowded tropical cities, we need new ways that balance the needs of people, the environment, and the economy.This study looks at ways mixed-use developments on Lagos Island, Nigeria, could include biophilic design and productive green infrastructure as part of efforts to breathe new life into the area. We collected information using structured questionnaires from 303 architects, urban planners, and real estate developers registered with ARCON.SPSS was used to run the analysis and get both descriptive and inferential results. While correlation and regression analyses examined connections between professional experience, design adoption, and perceived urban regeneration success, descriptive statistics described respondents' awareness, adoption, and perceived efficacy of biophilic and PGI tactics. The results show that although there are chances for ecological regeneration, Lagos Island's mixed-use areas are limited by excessive density, a lack of open space, inadequate waste management, and socioeconomic inequities. Green façades, rooftop gardens, and courtyards were found to be the most flexible approaches, and respondents showed a moderate to high awareness of biophilic principles. Productive green infrastructure is becoming more and more popular, and its incorporation is closely linked to perceived gains in social interaction, urban biodiversity, thermal comfort, environmental resilience, and economic value. A framework for policy, planning, and design interventions in tropical urban contexts is provided by the study's conclusion that integrating biophilic design with productive green infrastructure offers a workable, multifaceted strategy for developing mixed-use developments that are resilient, liveable, and economically sustainable.
