The study determined the impact of Green River Project on socio-economic development of rural
lives in Rivers State, Nigeria. Copies of the questionnaire were used in eliciting data from 90
randomly selected beneficiaries. The impact measuring model and the Wilcoxon signed-rank
test were used for data analyses. Results indicated that of the 25 development indicators studied,
the Project made a higher impact on 18 indicators on beneficiaries, while low impact was
recorded on 7 indicators. Impact of socio-economic indicators achieved within the Project did
not differ significantly with those achieved before participating in the Project. Sustained effort of
the Project is recommended to improve on the magnitude of the values of higher impact achieved
by the Project.
