River Zambezi & The Batoka Gorge Project

River Zambezi & The Batoka Gorge Project
  • Context:

  • Zambia and Zimbabwe have recently pledged seed capital to push forward the Batoka Gorge Hydro Electric Scheme (BGHES) on the Zambezi River.

  • This decision comes despite strong warnings from environmentalists and researchers about the project's long-term viability due to climate change

  • The Batoka Gorge Hydro Electric Scheme (BGHES)

  • It is a 2,400 MW hydropower project located on the Zambezi River, a short distance downstream from Victoria Falls.

  • It is a bi-national project shared between Zambia and Zimbabwe.

  • The objective is to supply 1,200 MW to each country, alleviating severe power deficits in the region.

  • Concerns:

  • Climate Viability:

  • Studies indicate that climate change is causing erratic rainfall and increased evapotranspiration, leading to declining water levels in the Zambezi.

  • Research suggests that reduced river flows could make the project financially unviable, potentially failing to reach anticipated production levels even under favorable conditions.

  • The project is managed by the Zambezi River Authority (ZRA), which also oversees the existing Kariba Dam.

  • Geographical Significance of the Zambezi River:

  • It is Africa's fourth-longest river (after the Nile, Congo, and Niger) and the longest east-flowing river in Africa.

  • It originates in Zambia and flows through Angola, Namibia, Botswana, Zimbabwe, and Mozambique, eventually emptying into the Indian Ocean.

  • The river already hosts two major hydroelectric dams:

  • Kariba Dam (shared by Zambia and Zimbabwe)

  • Cahora Bassa (in Mozambique).

  • It is home to Victoria Falls, one of the world's largest waterfalls and a UNESCO World Heritage site.
