Generation of urban solid waste is estimated to be increased by as much as 300 per cent in Sub-Saharan Africa (SSA) from 174 million tonnes in 2016, to 522 million tonnes by 2050. About 70 per cent of the current generated waste is dumped in the open or mismanaged otherwise; hence this region is witnessing a burgeoning waste management crisis that is leading to irreversible environmental damage, as well as proving to be a serious economic challenge. The escalating challenge is often manifesting as overflowing dumpsites, polluted waterways, and public health hazards. The poor state of solid waste management is not attributable to a single cause, but is rather the product of a complex interplay of systemic failures. Among these, weak local governance, critical infrastructure deficits, and most fundamentally—a crippling absence of reliable data, form a vicious cycle that impedes effective planning and sustainable solutions.
Local governments are often the primary point of breakdown. Many municipal governments in SSA are severely under-resourced and lack the technical capacity, institutional frameworks, and political will to manage waste effectively. Responsibilities are frequently fragmented across different agencies with overlapping mandates, leading to a lack of accountability and coordination. Furthermore, rapid urbanisation has drastically outpaced the planning and budgetary capacities of city authorities. As a result, municipal waste collection services are often irregular and fail to cover entire cities, particularly sprawling informal settlements. This governance failure creates a vacuum where unregulated private actors and informal waste pickers become de facto managers of the waste stream, operating without formal recognition, protection, or integration into a city-wide system.
