“…Mangroves stand out as unique wetland ecosystems found along coastal regions in the tropics and subtropics, and they are of paramount importance in maintaining the healthy functioning of coastal ecosystems [1]. In Africa, their overall extent is estimated at approximately 3.2 million hectares, with a distribution of 63% along the Atlantic coast and 37% along the coasts of the Indian Ocean and the Red Sea [2].…”

“…Furthermore, mangrove forests, crucial for coastal communities as a source of livelihood [3], play an essential role in enriching estuarine and coastal environments with nutrients through their litter [4]. These ecosystems are widely recognized globally as some of the most productive natural ecosystems, including essential nurseries for a multitude of aquatic species [1]. Their importance as such for many coastal communities, whose…”

“…First, they provide a wide range of services, including material services such as fishery products, timber, firewood, fodder, and medicinal plants [2]. They also offer cultural services, such as ecotourism, leisure, aesthetic appreciation, and religious aspects [1]. Thus, many inherent values or functions of mangrove ecosystems have led to a significant increase in their exploitation [1].…”

“…However, the overexploitation of woody resources, particularly mangroves in the Wouri estuary, by various groups of actors, treated as a common good with a low capacity for exclusion and growing rivalry, has led to a reduction in their fundamental productivity [1,7]. This situation therefore raises issues for their maintenance and sustainability.…”

Mangrove ecosystems provide key ecosystem services in coastal areas. This study describes the riparian mangrove of the Wouri estuary, in the Douala region (Cameroon), emphasizing the changes in this ecosystem over the past decade and its current state. It highlights the different groups of actors who participate in the management and regulation of the resource. Finally, an analysis of the governance of the mangrove wood resource based on the theory of common goods by Elinor Ostrom (1990) is proposed by examining the results obtained from the previous points. The scientific interest lies in contributing to a better understanding of the socio-ecological changes in the mangrove in the context of increasing anthropogenic pressures, highlighting the governance challenges and conservation opportunities in a strategic region of Central Africa. This research reveals complex processes that characterize mangrove ecosystems on the Manoka and Cap Cameroon Islands. The lack of urbanization regulations, continued infrastructure growth, repeated flooding, and coastal erosion all have a negative impact on natural landscapes and forests. The use of wood for smoking and fishing, as well as coastal pollution resulting from deficient garbage management, also have a considerable influence. Strategic interventions are needed to ensure sustainable ecosystem management. Recommendations include the application of rules to prevent forest overexploitation.

Predicting the distribution, structure, and biomass of mangrove forests is an area of high research interest. Across the Atlantic East Pacific biogeographic region, three species are common and abundant members of local mangrove communities; Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa. Biomass prediction for these species has relied on two approaches: site‐specific allometries based on the idea that environmental/climatic differences between sites drive growth differences, or the use of common allometric equations based on the idea that site driven differences are minimal. Meta‐analyses of global compilations of interspecific plot level data (e.g., mean canopy height, stand basal area) show trends in size and structure with climatic variables, however this has not been critically evaluated across these species using empirical allometric growth functions. We compared allometric equations derived from 590 individuals within and across nine broadly distributed sites at interspecific and intraspecific levels and explored the influence of climatic variables on allometric slopes and intercepts. Assessing variables that can be used to predict biomass in the field (height, diameter at breast height (DBH), canopy spread), we find interspecific root mean squared errors similar to or smaller than most intraspecific or site‐specific equations, particularly when examining sites with sample sizes above recommended values. We also find significant effects of several climatic variables on growth allometries with the strongest effects from minimum temperature followed by precipitation seasonality. Our results suggest that while climate has a clear influence on mangrove allometric growth, common equations may have utility in biomass prediction. Future methodological improvements, particularly larger sample sizes across the entire available size range, combined with data from a broader range of growth conditions will further inform which allometric relationships exhibit the most variability within and across sites and which variables best predict mangrove biomass.
