Wetlands Distribution and Socio-economic Development in the Coastal Area of Akwa Ibom State: Emerging Sustainability Threats

Wetlands in Akwa Ibom State, Nigeria, represent critical "natural sponges" that sustain biodiversity and regional socio-economic stability, yet they are currently declining at a rate that threatens long-term coastal resilience. This study evaluates the distribution of saltwater, brackish water, and freshwater wetlands across eight Local Government Areas (Ikot Abasi, Ibeno, Mbo, Esit Eket, Uruan, Onna, Mkpat Enin, and Itu) and investigates the direct correlation between wetland density and household wealth, food security, and disaster resilience. Employing a mixed-methods approach, the research integrates a quantitative survey of 400 households with qualitative Participatory Rural Appraisal (PRA) tools, including sketch mapping and Key Informant Interviews (KIIs). Findings reveal a significant landward migration of the "saltwater line," particularly in Ibeno and Mbo, where industrial canalization has facilitated saltwater intrusion, leading to the "smothering" of indigenous mangroves and a subsequent "nose-dive" in forest density. Conversely, freshwater marshes in Itu and Uruan are undergoing "anthropogenic stasis" due to sand mining and urban infilling. Quantitative analysis demonstrates a direct positive correlation between healthy wetland ecosystems and artisanal fishing profit margins, while degraded zones exhibit a "Resilience Gap," trapping low-income households in a cycle of disaster-induced indigence. The study further identifies a "patchwork of legislation" and jurisdictional overlaps that obscure industrial compliance and facilitate the spread of the invasive Nypa palm (Nypa fruticans). The research concludes by proposing a "Polycentric" governance model that harmonizes formal state enforcement with traditional "sacred grove" protections. By treating wetlands as essential natural infrastructure rather than "wastelands," this strategic framework provides a roadmap for sustainable development within Nigeria's emerging Blue Economy.
