The Zambezi River Authority (ZRA), a bilateral organisation equally owned by the Governments of Zambia and Zimbabwe, proposes the development of the Batoka Gorge Hydro-Electric Scheme (BGHES) (hereinafter referred to as the Project). The Project will be situated approximately 47km downstream of the Victoria Falls, on the Zambezi River.

As part of the statutory requirements in Zambia and Zimbabwe, before the Project commences, an Environmental and Social Impact Assessment (ESIA) must be completed, and environmental authorisation granted for the Project by both the Zambian and Zimbabwean environmental regulatory authorities. In addition to these requirements, as the BGHES requires the support of international lenders, the ESIA specific to this Project will need to be undertaken to align with international good practice guidelines such as the World Bank’s Environmental and Social Standards and International Hydropower Association (IHA) sustainability protocols.

An ESIA was commissioned in mid-2014, by the ZRA with Environmental Resources Management Southern Africa (Pty) Ltd. (ERM) and its local partners (Kaizen Consulting International in Zambia and Black Crystal in Zimbabwe) as the Project Consultants to undertake this work. Prior to the end of 2015, ERM and its team had completed the Scoping Phase of the Project, which entailed extensive stakeholder engagement and the necessary environmental and social baseline studies had been completed in order to inform the content of an ESIA. A Draft ESIA and Environmental and Social Management Plan (ESMP) was prepared and submitted to the ZRA for its review in late 2015.

The ESIA was then placed on hold for numerous technical and commercial reasons; however, discussions held between ERM, the ZRA and the World Bank (the funder of the feasibility studies) resulted in recommencement of the ESIA process for the Project in October 2018. Given the time that has elapsed since baseline data was gathered for the ESIA studies, ERM is in the process of updating various studies, and draft the Environmental and Social Impact Assessment (ESIA). The Draft ESIA will contain a detailed project description, provide the assessment of impacts, and proposed mitigation measures. The Draft ESIA will be released for a 30 day comment period, during which time ERM will host a number of feedback meetings to discuss the findings of all environmental and social studies, and allow stakeholders opportunity to ask further questions and provide comment on the Draft ESIA.

Following the disclosure of the Draft ESIA, the report will be finalized and all comments received, together with a response from the project team, will be submitted to environmental authorities in Zambia and Zimbabwe (ZEMA and EMA) for their consideration. To note is that the project cannot progress into the construction phase until such time that the ZEMA and EMA have approved the ESIA.

This website serves to disseminate Project information as it becomes available. If you have any questions, or wish to register as an interested and affected party for any of the EIAs, please contact ERM (South Africa), Felix Chisha (Zambia) or Black Crystal (Zimbabwe), contact details are provided in the right-hand box.


On 3rd March 2020, ERM notified stakeholders of the availability of the draft ESIAs for public review and comment, and invited stakeholders to attend ESIA disclosure meetings in Zambia and Zimbabwe, which were proposed to take place during April 2020. In light of the COVID-19 (Corona Virus Disease 2019) pandemic, the Authority and ERM made the decision to postpone all public disclosure meetings. This decision was in response to government-mandated travel restrictions and bans on gatherings of more than 100 people, which were imposed within certain southern African countries.

Stakeholders were invited to participate in a webinar where key findings of the ESIA were presented, followed by a Q&A session.
