The Isoko people migrated historically from the Benin Kingdom in nearby Edo State, and therefore share some cultural similarities with this state. The area later formed part of Bendel State, before Bendel State was split to form Edo and Delta states.
The Isoko South and North Local Government Area was established on 23 September 1991, when the former Isoko Local Government Area was subdivided. The area produces a large component of the oil and gas resources of Delta State.
The Isoko South Local Government Area covers a low-lying section of the larger Niger Delta Basin, interspersed with streams, canals and rivers. It is located in a region of deciduous and evergreen forests, with patches of mangrove forest, as well as a forest reserve along the Aviara clan area. 
The local population are primarily of the Isoko people, which is subdivided into several clans. Clans inhabiting Isoko South include the Aviara, Olomoro, Emede, Enhwe, Erohwah, Igbide, Irri, Okpolo, Oleh, Umeh and Uzere. The Isoko language is predominant in much of the area.
The traditional occupation of the people of Isoko South is fishing and agriculture.

Environmental challenges and projects
Oil and gas exploration activities began in the area in the early 1950s, and the second oil well in Nigeria was discovered in Uzere, Isoko South, in 1958. The massive growth of the oil and gas industries has created significant environmental challenges, and have been a source of much concern for the local government.
Challenges such as gas flaring, oil spills from pipelines, deforestation and waste miss-management have been made more serious by federal laws which centralise control of the oil rich land and allow local government relatively little control over activities. Due to such concerns, in 2001, the Isoko South Local Government joined ICLEI - Local Governments for Sustainability, the first local government in Nigeria to do so.
The local government has since engaged in extensive project work to combat the effects of oil and gas pollution. It has promulgated a law that makes Environmental Impact Assessments (EIA) compulsory for all developmental and industrial projects, and has also carried out environmental auditing with environmental regulators and NGOs in the local government area. Large tree planting projects have also been launched in collaboration with community-based organisations and with UNDP GEF/SGP support.
