Isoko is a region of Delta State in southern Nigeria and is inhabited by an ethnic group of the same name, the Isoko people. The region is divided into two Local Government Areas, Isoko North (headquartered at Ozoro) and Isoko South (headquartered at Oleh).
This region used to be a part of the defunct "Mid-West Region". It later became part of Bendel State, before Bendel State was split to form Edo and Delta states.
The Isoko region is located in Delta State of modern Nigeria.
Isoko region is in the tropical rain forest area of the Niger-delta. The region experiences high rainfall and high humidity most of the year. The climate is equatorial and is marked by two distinct seasons. The Dry and Rainy seasons. The Dry season lasts from about November to April and is significantly marked by the cool "harmarttan" dusty haze from the north-east winds. The Rainy season spans May to October with a brief dry spell in August.
Some major towns in Isoko region are:
The main economic activity is food crop farming. And the staple food crops include cassava and yams. There is also the widespread production of palm oil and palm kernels. Limited amount of hunting and fishing is also done. Women form a large proportion of the farming population. They also engage in trade of food crops for cash to meet other basic household needs. On market days, it is common to see Isoko women peddling their assorted goods around neighboring villages.
Cassava is the source of most of the foods consumed by the Isoko people. Garri, starch meal (Ozi), Egu are cassava derivatives.
Food crop production has been declining rapidly recently. This has been largely attributed to soil damage resulting from frequent crude oil spills from pipelines belonging to some of the major oil producing companies (including Shell Petroleum Development Company (SPDC), whose pipeline network transverse the landscape). This has led to large-scale frustrations with Shell Petroleum Development Company, and has resulted in skirmishes and, recently, kidnappings for ransom in some neighboring communities.
There is no definitive population census figure on the region of Isoko and, indeed, most of Nigeria. The various Nigerian census figures have been controversial and are deemed unsupportable.
