Redefining planning: Emerging research specializations in Nigerian urban and regional planning

Abstract

Urban and regional planning in Nigeria is undergoing a significant transformation, with increasing specialization shaping research priorities and professional practice. This study examines emerging areas of specialization in Nigerian planning research, analyzing self-reported expertise from 208 scholars across 40 institutions. Using qualitative thematic analysis, the study categorizes 87 distinct specializations into eight broad domains: Housing and Urban Development, Environmental Management and Sustainability, Transport and Infrastructure, Land Use and Regional Development, Social and Community Development, Economic and Resource Management, Health and Safety, and Innovative and Emerging Areas. Findings reveal a dominant focus on Housing and Environmental Management, reflecting urgent urbanization and sustainability concerns, while areas such as Health, Economic Planning, and Technological Innovation remain underexplored. The study also identifies institutional and regional disparities, with universities leading theoretical advancements and polytechnics emphasizing applied research. The South-West region emerges as a research hub, particularly in Housing, Environmental Sustainability, and Transport Planning. The findings contribute to international debates on generalist vs. specialist planning, highlighting both the benefits and challenges of increasing specialization. The study underscores the need for interdisciplinary collaboration and policy integration to ensure a balanced and inclusive approach to urban and regional planning in Nigeria. Future research should explore emerging fields such as climate resilience, smart urban management, and economic sustainability to address contemporary and future urban challenges.
