Background The African Great Lakes and other surface water resources are gradually becoming nutrient enriched

These nutrients may be coming from agricultural land, either as direct runoff, or through the atmosphere following biomass burning and wind erosion of exposed soils.

Atmospheric deposition is a major component of the nutrient budgets into these waters.

Some of the direct effects of nutrient enrichment include eutrophication, hypoxia and fish kill.

GEF International Waters Project on African Great Lakes – indentified the links between increasing eutrophication and atmospheric deposition of macronutrients.

The EADN is a monitoring program within the equatorial region of Africa with about 12 participating countries established

to assess the deposition of nutrients from the atmosphere to determine its effects on surface water eutrophication and agriculture

EADN Project Status in Nigeria Collection monthly atmospheric deposition samples since July, 2013.

Analysis of samples in France along with those of other countries.

Only the atmospheric sampler still installed.

Steering Committee about to be inaugurated to coordinate the EADN activities in Nigeria.

Members composed of representatives from the FMENV, Ministries of Water Resources and Agriculture as well as other stakeholders.

Slow deployment of other equipment to the Ibadan Station

Funding for the activities of the Local Steering Committee
