The promulgation of the Environmental Management Act, 2015 of Zanzibar is a relatively new development. It has ushered optimism in the environmental management and protection realm in Zanzibar. The Act repeals and replaces the framework Environmental Management and Sustainable Development Act of 1996. Ostensibly this development seeks to reflect the Revolutionary Government of Zanzibar’s (RGZ) concerted effort to address the rampant environmental degradation on the Isles by taking into account a number of developments at the international and local levels. The article provides a critical analysis of the new Act by, inter alia, making some comparisons with the repealed framework law. Its main thesis posits that although the intention of the RGZ is plausible, the new law is not an inviolable recipe for addressing the major challenges of environmental degradation facing the Archipelago.
