Summary

Nick Ashton-Jones, with Oronto Douglas and Susi Arnott Niger Delta Ecosystems: the ERA Handbook… (1998)

The landscapes that we see around us today are the visible manifestations of human ecosystems: the concepts of 'wild landscapes' or 'natural landscapes' that imply some sort of landscape that has evolved without the aid of people is nonsense.
For the greater part of our history, people have lived in ecological balance with the environment. We lived as viable people exploiting the ecosystems of which we were part in a sustainable manner. Thus our ecosystems remained healthy and were able to continue to supply the resources that we required from them.

These definitions help our understanding but the ecozones are no more than convenient boundaries for the description of the Niger Delta ecosystem as a whole. An ecosystem which itself is no more than a convenient boundary for study, and actually an interrelated part of a hierarchy of ecosystems. A hierarchy that may, for example start with the West African biogeographical sub-region and reach down to the estuaries of the Niger Delta and defined species populations that live in them. These ecological interrelationships become more obvious when they are subjected to human influence.
