Reducing industrial pollution in the Niger River Basin

Reducing industrial pollution in the Niger River Basin

The Niger River is the third-longest river in Africa, running for 4,180 km (2,600 miles) from its source in south-eastern Guinea, through Mali, Niger and Nigeria, before discharging via the Niger Delta into the Gulf of Guinea in the Atlantic Ocean. Tributaries that run through a further five countries feed into the mighty Niger.

Hundreds of millions of people in West Africa depend on the river and its tributaries, for drinking water, for fish to eat, for irrigation to grow crops, for use in productive processes, and for hydroelectric power.

The health of the Niger River Basin is vitally important for the people and for the environment of West Africa. But this health is endangered by land degradation, pollution, loss of biodiversity, invading aquatic vegetal species and climate change.

To both assess and address these environmental issues, a Global Environment Facility (GEF)-funded project has brought together international, regional and national entities to work on integrated water resources management for the benefit of communities and the resilience of ecosystems. (Project details can be found here.)

One part of the early project research found that as the Niger River passes through Tembakounda, Bamako, Gao, Niamey, Lokoja and Onithsa - major trading, agro-processing and industrial cities - wastewater and other polluting substances are discharged directly into the river, often without consideration for the environment. National governments of the countries which the river runs through are either unable to deal with the accumulated environmental problems and/or are ineffective at preventing, regulating, reducing and managing pollution from industrial activities.

For this reason, one component of the GEF project, implemented by the United Nations Industrial Development Organization (UNIDO), will facilitate the Transfer of Environmentally Sound Technology (TEST) to reduce wastewater discharges and pollution loads into the Niger River.

Despite the limitations on travel resulting from measures to halt the spread of the coronavirus, in August this year, UNIDO successfully identified and engaged with 19 pilot enterprises in various sectors, including pharmaceuticals, mining and agribusiness, operating in 'pollution hotspots' in the countries of the Niger River Basin. This number exceeds the original target of one enterprise per country. 

UNIDO experts are now introducing and sharing the Transfer of Environmentally Sound Technology (TEST) methodology with the pilot enterprises. In essence, this will mean the application of a set of tools including Resource Efficient and Cleaner Production, Environmental Management Systems, and Environmental Management Accounting, which will lead to the adoption of best practices, new skills and a new management culture.

Armed with these tools, the enterprises will be able to reduce product costs and increase productivity, while reducing the adverse environmental consequences of their operations. An awareness-raising campaign will be carried out so that the demonstration effect resonates across the Niger River Basin, prompting other enterprises to follow suit.
