Institutional Capacity Development and Solid Waste Management in Lagos, Nigeria

Rapid urbanization, population growth, and inadequate infrastructure have intensified waste management challenges in the State, underscoring the need for stronger institutional systems. To this premise, the study investigated the influence of institutional capacity development on sustainable solid waste management in Lagos, Nigeria. A mixed-methods research design was employed, combining quantitative surveys with qualitative interviews and focus group discussions involving key stakeholders such as government agencies, private sector operators, and community representatives. Quantitative data were analyzed using descriptive statistics, correlation, and regression techniques, while thematic analysis was applied to qualitative responses. Findings reveal that institutional capacity development particularly policy formulation, stakeholder engagement, human resource training, and resource allocation significantly improves waste recycling and overall solid waste management performance in Lagos. The results show a positive and significant relationship between institutional capacity strategies and solid waste management outcomes, highlighting the importance of coordinated policy implementation and strengthened stakeholder participation. The study recommended enhanced capacity-building programmes, improved stakeholder coordination, and stronger policy frameworks, alongside public-private partnerships to promote recycling and reduce environmental and public health risks. Strengthened institutional systems are essential for achieving sustainable waste management in Lagos State.
