The blue economy, which involves the sustainable use of ocean and coastal resources for
economic growth and environmental sustainability, has increasingly gained global recognition
as a strategic pathway for economic development in coastal regions. Lagos State, Nigeria, with
its
extensive coastline and maritime resources, possesses significant potential for the
development of blue economy sectors such as fisheries, maritime transport, and coastal tourism.
However, these opportunities remain largely underutilized. This study investigates the impact of
the blue economy on economic development in Lagos State. A descriptive correlational research
design was adopted, and data were collected from 100 respondents through structured
questionnaires. The Chi-Square Test of Independence was employed to examine the relationship
between blue economy activities and economic outcomes such as job creation, income
generation, and sustainable development. The findings reveal that the blue economy significantly
contributes to employment opportunities and income generation in Lagos State, with fisheries
and marine tourism emerging as key drivers. Nevertheless, challenges such as inadequate
infrastructure, weak policy implementation, and environmental degradation limit the full
realization of these benefits. The study therefore recommends increased government investment
in maritime infrastructure, strengthened environmental management policies, and strategic
promotion of coastal tourism and fisheries to enhance the contribution of the blue economy to
sustainable economic development in Lagos State.
