Emerging environmental issues refer to topical environmental issues that are continually evolving and expanding, but are yet to receive sufficient attention. In this regard, addressing them early enough provides an opportunity to manage before they become a serious threat to human health and the environment. In recent years Tanzania has experienced a number of new environmental challenges including electronic and electrical equipments waste (or commonly termed as e-waste); Invasive Alien Species (IAS); Genetically Modified Organisms (GMOs); and Biofuels.
