This paper examines the implementation of Integrated Water Resources Management (IWRM) in the Cross river basin, Nigeria. The Cross River Basin Development Authority (CRBDA) was established in 1976 with a mandate for integrated development, using the abundant water resources available in the region. Thirty years after the creation of the CRBDA, there is still a large gap between the original objectives and the actual delivery of services to meet the needs of the people. A wide range of study methods, including stakeholder meetings, focus group sessions, interviews and observations at village meetings of selected communities was used to examine the implementation of IWRM against the expectations and needs of the people. The paper concludes that IWRM in the Cross river basin (CRB) has not been very successful. This is attributed to a number of institutional factors, including legal, political, administrative and financial obstacles. This paper recommends that IWRM policies in the CRB should be reformed to reflect local circumstances and conditions.
