Integrating Sustainable Development Goals into Urban Planning to Advance Sustainability in Sub-Saharan Africa: Barriers and Practical Solutions from the Case Study of Moundou, Chad

The accelerating pace of urbanization, coupled with changes in land-use patterns and the exacerbation of extreme climatic events—marked by heightened unpredictability and severity, particularly in regions of the Global South—necessitates a thorough reevaluation of urban governance and management frameworks. In response to these challenges, it is essential for strategies to integrate local socio-economic specificities while navigating the inherent complexities of these issues, leveraging contextually appropriate resources within a sustainability paradigm. In this regard, contextualizing and incorporating the Sustainable Development Goals (SDGs) into urban planning frameworks is crucial for advancing urban sustainability. However, significant obstacles hinder their effective integration at the urban scale, particularly in fast-evolving, resource-constrained settings. This study seeks to address this critical gap by systematically examining the barriers to SDG integration in urban planning within sub-Saharan Africa. For this purpose, Moundou, Chad, is used as a representative case study, reflecting both the challenges and opportunities of urban sustainability in the region. A hybrid methodology underpins this research, combining in-depth interviews with key development stakeholders, a detailed review of strategic documents aligned with the SDGs, and semi-structured questionnaires to capture diverse perspectives. The results reveal that the institutional dimension constitutes 38.46% of the barriers identified by stakeholders, with key challenges including limited capacity for long-term planning, a lack of expertise, and inadequate multisectoral coordination, among others. In addition, the economic and socio-cultural dimensions each represent 23.08% of the identified barriers, encompassing issues such as dependence on external funding, the high cost of green technologies, low public awareness, and resistance to change within communities. Finally, the data access dimension ranks last, accounting for 15.38%. To overcome these challenges, it is essential to implement mechanisms that strengthen institutional capacities, promote cross-sectoral collaboration, enhance public awareness, and cultivate a culture of adaptability and innovation within local communities. Furthermore, improving data accessibility and reinforcing financial mechanisms are vital to addressing these barriers comprehensively.
