“…The creeks harbour large areas of mangrove forests which are very highly exploited for wood. The soils are ferralitic, volcanic and very fertile [21]. The principal activity employing over 75% of the cosmopolitan population is agriculture.…”

Mangrove forests are among the most productive natural ecosystems in the world and offer invaluable ecological functions, yet are seriously threatened. Anthropogenic activities within mangroves can cause alteration of physicochemical parameters of sediments which in turn affect the assemblage of biological communities. This study was designed to assess the impact of anthropogenic disturbances within the Tiko mangroves on the benthic algal community. Perturbations were assessed through questionnaires. Two sets of composite sediment samples were collected for physicochemical and algal analyses from seven sites within the mangroves following standard methods. Seven drivers of change were identified (agriculture, human settlement, logging, fuel wood collection, fishing, fish smoking and petty trading) as the main perturbations of the ecosystem. A total of 141 benthic species were identified at the different sites. The Bacillariophyta were the most abundant with 60 algal species followed by Chlorophyta with 38 algal species. The most dominant species were Chlorobotrys regularis (50) and Microcytis sp (38).Site 3 (settlement site) was the most diversed with 72 species. The mean abundance of benthic algae ranged from 0.59 ± 0.17 to 2.08 ± 0.58. High concentrations of nutrients and the presence of Bacillariophyta and Microcystis suggest pollution. There is a need to monitor activities carried out around the mangrove ecosystem with respect to quantity and quality of waste discharged into the environment since this is a highly sensitive environment.

“…The value of aboveground carbon stock (318.92 Mg C ha -1 ) in the plantation was found to be higher than the carbon stock reported by other workers in other places. For instance, Duguma et al [19] reported aboveground biomass carbon stock of 152 Mg C ha -1 for a cocoa agroforestry in South Cameroun; Egbe et al [32] reported carbon stock in oil palm to range from 66 to 88 Mg C ha -1 and in rubber to range from 248 to 264 Mg C ha -1 in Cameroun. van Vuuren et al [33] has also reported carbon storage for a 25 years old Pinus patula plantation and Eucalyptus grandis plantation to be 62.6 and 269.9 Mg C ha -1 respectively in South Africa.…”

This study investigated carbon stock in above-ground biomass across different physiognomies in Obafemi Awolowo University tropical rainforest ecosystem. This was with a view of increasing the understanding of carbon cycle in tropical rainforest in Nigeria. Two 20 m x 20 m plots were marked out in the secondary forest, Tectona grandis and Riparian vegetations. Total enumeration was carried out for the living tree, the Diameter at Breast Height (DBH) of trees ≥10 cm were measured at 1.3 m above the ground and height was also determined using a ranging pole and Haga altimeter. Aboveground carbon stocks in standing trees ranged from 218.24 to 318.92 C t ha-1 with the highest value in Tectona grandis plantation. Trees with DBH size class 11-20 cm contributed more to Carbon stock in secondary forest and Tectona grandis plantation, while size class ≥60 cm contributed more in the riparian vegetation. Tectona grandis plantation proved to be better in mitigating carbon in our environment and this result will enhance better estimates of local and regional carbon stock which is crucial to addressing the problems of climate change.

Limited modeling studies are available for the process-based simulation of ecosystem services (ESS) and biodiversity (BD) in agroforestry systems (AFS). To date, limited field scale AFs models are available to simulate all possible ESS and BD together. We conducted an extensive systematic review of available agroforestry (AF), BD, and soil erosion models for the simulation potential of seven most desirable ESS in AFS. Simple to complex AF models have an inherent limitation of being objective-specific. A few complex and dynamic AF models did not meet the recent interest and demands for the simulation of ESS under AFS. Further, many ESS modules especially soil erosion, GHGs emission, groundwater recharge, onsite water retention, nutrients and pesticide leaching, and BD are often missing in available AF models, while some existing soil erosion models can be used in combination with AF models. Likewise mechanistic and process-based BD diversity models are lacking or found limited simulation potential for ESS under AFS. However, further efforts of model development and improvement (integration and coupling) are needed for the better simulation of complex interactive processes belonging to ESS under AFS. There are different possibilities but a proficient modeling approach for better reliability, flexibility, and durability is to integrate and couple them into a process-based dynamic modular structure. Findings of the study further suggested that crop modeling frameworks (MFW) like SIMPLACE and APSIM could be potential ones for the integration and coupling of different suitable modeling approaches (AF, soil protection, GHGs emission, flood prevention, carbon sequestration, onsite water retention, ground recharge, nutrient leaching, and BD modules) in one platform for dynamic process based ESS estimation on daily basis at the field scale.
