The Agulu-Nanka gully erosion has the potential for an ecological disaster, because the erosion causes frequent landslides. In the Nanka Community, Eke-Ntai in Amako Village, was reported to be a flourishing Slave Market during the period of the trafficking in human cargo and popularized by Ezenwenwe. The menacing erosion in Nanka today is said to have its origin in the notorious market. A Soil Erosion Management Expert- Benneth Obele- in 2009 wrote that " erosion disaster in Nanka Ududo dates back to early 1920s when the gully sites were first observed near Eketai Market in Amako village as well as near Ududonka Shrine. The lucrative and hidden business in human trafficking or slave trade conducted within those two sites led to development of hidden bush foot pathways that were heavily flooded from neighbouring communities precipitating gully erosion" On June 19, 2008, a landslide cut off Amako village from the rest of Nanka. In response, the Nanka Patriotic Union, social- set up measures for capacity building of inhabitants on application of control measures. Members of the Nanka community donated nearly 10,000 cashew seedlings for erosion control in the 20 erosion sites scattered in the town. The issue was discussed at the Oririji Festival on August 21 of 2010, where Igwe G.N Ofomata, Obu Nanka, addressed the people. Igwe Joseph Nwankwo Ezenekwe was traditional ruler of Nanka from 1977-1982..
