Background to Environmental Degradation in Ogoniland An Ogoni woman draws water from an open well. With a rich and diverse culture, the Ogoni have lived in the Niger Delta for hundreds of years © UNEP UNEP ENVIRONMENTAL ASSESSMENT OF OGONILAND Agbada Formation and Akata Formation. The Background to Benin Formation is comprised of multiple layers Environmental of clay, sand, conglomerate, peat and/or lignite, all of variable thickness and texture and covered by Degradation in overburden soil. Clay beds are discontinuous and groundwater is therefore present both as localized Ogoniland aquifers or in hydraulically interconnected aquifers. The ground characteristics are consistent Ogoniland is characterized by typically deltaic with deltaic environments, where erosion and features: uneven terrain, numerous creeks, shallow deposition of sediments constantly shift the course brackish water bodies and a variety of vegetation of channels, tributaries and creeks. types including swamp forest. The following section describes in detail Ogoniland’s environmental Groundwater setting and oil industry operations. Ogoniland’s aquifers are a crucial resource upon 2.1 Environmental setting in which the region’s entire population depends for Ogoniland and the Niger Delta drinking water. The protection of these aquifers is therefore vital. These aquifers are very shallow, with Geology the top-most groundwater levels occuring anywhere between close to the surface and a depth of 10 The Niger Delta is the product of both fluvial metres. To tap the aquifers, Ogoni communities and marine sediment build-up since the upper typically construct open, hand-dug wells about Cretaceous period, some 50 million years ago. 60 cm in diameter and water is abstracted either Over time, up to 12,000 metres of shallow manually or with pumps.

Tree and shrub cover remains important in uncultivated areas. Other non-timber forest products which are important, especially for poorer households, include grass cutters, bamboo for staking of yam (edible perennial herbaceous vines), medicinal plants, vegetables, fruits and snails. An agriculture-based economy and an increasing population have meant that most of the rainforest that once covered Ogoniland has been cleared for farming. In many places the practice of integrating farming and forestry remains, covering large areas of land and consisting mainly of oil palm and rubber plantations. The farm animal population too has increased with population density, with the animals also involved in nutrient recycling [5]. In Ogoniland, only small-sized sacred forests (shrines) of usually less than 1 ha remain in a relatively undisturbed state, while most of the remaining vegetation is highly degraded. Original vegetation consists mainly of mangroves. Local communities The Ogoni are a distinct people who have lived in the Niger Delta for hundreds of years.
