The Core Periphery Model (CPM) explores the imbalance in regional development and
offers explanations with possible solutions. This paper used Adamawa State of Nigeria as a case study in
investigating this model and in proposing a regional development plan for the State. The low level of, and
imbalance in regional development observed in the State suggested the research. Data used for the study
were sourced from official documents of the State including settlements listing by districts and Local
Government Areas (LGAs) vis-à-vis their population, human activities, infrastructure, resources and
development potentials. Data obtained and analysed established the susceptibility of the State to the Core –Periphery Model manifested by low and uneven regional development in the State and that the
peripheral settlements are too fragmented spatially and demographically to attract nominal development. The State is lowly served infrastructurally, industrially, and in terms of tourism and mineral exploitation
but has high agricultural production. It generates very low revenue internally and community
participation in developmental efforts is low. Based on these findings, 3 alternative concepts – Peripheral
Development (PD), Intermediate City Development (ICD) and Integrated Peripheral Development (IPD) – were developed, evaluated and the most weighty concept (the lCD) chosen and used to propose the CPM
for Adamawa State regional development. The proposed actions were phased and implementation
strategies advanced. Recommendations of the study include industrial, infrastructural, agricultural,
tourism and mineral resources development; Border Area Industrialization and Commercialisation
Programmes and other socio–economic and environmental development projects.
