The study analyses anthropogenic influence on the mangrove forests of the Cameroon coast and focuses on the development and improvement of the constructive- geographical foundations of rational nature management for the conservation and possible renewal of its natural resources base. The exploitation of mangrove forest landscapes has yielded significant benefits to the local population living within the mangrove forest limits, but the beneficiaries have not made commensurate investments in their sustainability and rational use. Therefore, this habitat must be carefully conserved or protected from wanton anthropogenic activities for the development purpose. The study made use primary and secondary data in establishing the facts analysed in this work. The secondary data comprised of materials of prominent authors who have contributed much to the findings related to coastal mangroves. Primary data collection was field visits carried out by the author in 2016. Questionnaires and semi- structural questions were used to collect information from mangrove exploiters. The findings confirm that the coastal mangrove forests in Cameroon have multiple functions beneficial to the communities adjacent to the coast, but, unfortunately, the beneficiaries have not made commensurate efforts to their sustainability and rationale. The Mangrove forests covered a surface area of 200 000 km2, but Cameroon lost 30 % of its mangrove forest cover in 1980–2006. If projected under ceteris paribus, Cameroon lost approximately 45 % of its mangrove forest cover in1980–2020. Haven understood that man has raped huge surfaces of mangrove forest for his selfish economic gains, the study proposed an urgent need for environmentally sustainable adaptive strategies like those earmarked in the Ramsay agreement and the ICZM (Integrated Coastal Zone Management) for the rational management of coastal mangroves in Cameroon.

Policy Scenario

Mangroves provide benefits and various services to local communities living along coastal areas, particularly fishery communities. Fishery community perceptions are significant in determining attitudes towards improving mangrove conditions, which can also be addressed through restoration activities. This research was conducted to analyze fisheries communities perceptions, willingness to pay (WTP) for mangroves restoration, and mangrove forest management strategies. Field surveys were conducted from July-August 2019 and February-March 2020. Primary data were collected from respondents in four regions (Kalianda Regency, South Lampung Regency, Bandar Lampung City, and Pesawaran Regency) in Lampung Province, Indonesia, which consist of fishers, shrimp farmers, crab and wood seekers, and finfish farmers. The respondents were 193 people, and four experts were involved in the policy scenario analysis. Results revealed a gap in the value of WTP among fishery community groups, in which the average value for fishers is lower than shrimp farmers. The years of formal education significantly influenced the WTP for mangrove restoration. Based on the scenario analysis, scenario 01 become a priority strategy, where four policies (P1 = Mangrove ecotourism development in Lampung Bay; P2 = Mangrove knowledge education and training on processing mangrove based products; P3 = Restoration and conservation of mangrove forests; and P4 = Community-based management for mangrove forests utilization) show high likelihoods to be simultaneously implemented for mangroves management, with mangrove ecotourism policy as the most decisive policy. For future research, other explanatory variables can be added, such as information on family member characteristics, and to develop a bottom-up policy scenario by identifying and involving the role of the local community.

Multiple funding mechanisms support restoration across the northern Gulf of Mexico. To maximize environmental, societal, and financial benefits of these investments, best use of available science is needed to inform project prioritization and planning processes. Synthesizing available data across the northern Gulf of Mexico can provide information on potential threats to, and benefits from, projects or suites of projects. To achieve this, subject matter experts from Alabama, Florida, Louisiana, Mississippi and Texas were identified with recommendations from each of the RESTORE Act Centers of Excellence. These experts provided known sources of Gulf-wide data and recommended metrics that would be most informative, resulting in 40 threat, 19 habitat and 10 community primary data layers. Two tessellated geospatial hexagon grids were generated to provide uniform coverage that encompassed a 25-mile buffer of the Coastal Zone Management Act (CZMA) boundary at a spatial grid resolution of 100 km2 and 1 km2. The two resultant grid domains included all counties in the five Gulf states determined by the National Oceanic and Atmospheric Administration (NOAA) as contributing to coastal watersheds. The varying grid resolutions allowed for data to be spatially visualized both at a broad Gulf-wide scale on the 100 km2 grid as well as at a regional and project level scale on the 1 km2 grid. The data layers were synthesized into combined layers of potential stress, potential ecological benefits, and potential community benefits. These layers support broad scale prioritization for restoration efforts, based on likelihood of success and desired outcomes. The synthesized data were discussed in the context of the five goals and four priority criteria of the Gulf Coast Ecosystem Restoration Council’s (RESTORE Council) aim of using best available science (BAS) to guide future funding for restoration at large and small scales.
