The Tanga UWASA Water Infrastructure Green Bond: Innovative Financing or Foreign Financial Dependence?

African non-central governments (NCGs) (i.e., sub-states, regions, cities, municipalities, local governments, etc.) are increasingly vulnerable to climate-induced impacts. This vulnerability has precipitated a shift towards climate finance instruments to meet the funding deficit for local adaptation and mitigation projects. A case in point is the Tanga (Tanzania) UWASA Green Bond—an instrument that raises critical questions about debt responsibility, the prioritization of bankable projects over community needs, and the risk of financialization of essential public utilities. In their 2024 study, Ohiocheoya Omiunu and Ifeanyichukwu Azuka Aniyie explore whether the Tanga UWASA bond represents true domestic capital mobilization or entrenchment of foreign financial dependence. The researchers argue that the Tanga UWASA bond exemplifies the promise and pitfalls of innovative climate finance in Africa, revealing the complexities facing African subnational governments (SNGs) as they navigate global financial architectures that may serve external interests over and above local development needs.
