Cocoa agroforests sustain ecosystem services (ESs) to varying degrees. These services are otherwise mostly provided by other non-cocoa shade or companion trees. However, the density of shade trees is associated with services and/or disservices that drive farm-specific tree management successions. Considering the growing impacts of climate crisis on farm productivity and the need for adaptation strategies, the ESs are increasingly provisional and contingent on the prevailing vegetation, land tenure, and management successions, amongst others social and ecological factors. To assess the temporal changes in shade management, we surveyed an age gradient of “family farms” in cocoa agroforests created from forest (fCAFS) and savannah (sCAFS) land cover. We evaluated the temporal changes in farm structure, relative tree abundance, and live aboveground biomass of the major canopy strata. We used a spatial point process and linear mixed effect analysis to assess the contributions of associated perennial trees (AsT) on farm rejuvenation patterns. The density of cocoa trees was inconsistent with farm age; this was significantly high on farms in sCAFS (1544 trees ha

This paper examines the degree to which public participation in concession-based forestry decision-making - as outlined by the Environmental Impact Assessment (EIA) Decree (No. 2005/0577/PM)-is taking place in eight forest-dependent communities of Cameroon. Of the total respondents that took part in the survey, only 39 per cent stated that they were involved in decisions concerning concession-based forestry. Furthermore, there seems to be a generally negative perception on the part of local communities towards the government’s implementation of public participation legislation in concession-based forestry decision-making. Obstacles to public decision-making process are identified and recommendations are proffered for more effective public participation.

Community-based Forest Operations (CFOs) have played a notable role in promoting sustainability within Cameroon’s indigenous forest-dependent communities, but they are fraught with a range of socio-economic and ecological hurdles. As a means of achieving more sustainable forest practices, one possible solution would be for CFOs to adopt forest certification, though various barriers would have to be overcome. Using a number of examples at the regional level, this paper examines the potential benefits and barriers to community forest certification in Cameroon. Specifically, the paper identifies these barriers as legislative and political, economic, and informational in nature. While adoption of forest certification hinges upon what initiatives are employed by CFOs, it is argued that there is also a need for the government of Cameroon to play a leadership role in removing hurdles and promoting the uptake of certification.

While the oil industry along the Atlantic coast of Cameroon has made important contributions to the national economy, this has been accompanied with adverse environmental impacts. There has been significant pollution from oil drilling, refinery waste, oil spillage, gas and flaring. After discussing these impacts, this paper argues that prevailing regulations are inadequate and need overhauling. It proposes that cleaner production requires:

The deleterious impact of industrial activities on safety health and environmental quality has motivated industries to adopt environmental management systems (EMSs). This paper examines the implementation of EMSs in industries that interact with the Atlantic coast of Cameroon, which has been plagued with effluents emanating from industrial activities. Through a questionnaire based survey that was conducted from January 2005 to June 2005 with all the industries along the Atlantic coast of Cameroon, this paper seeks to address the motivating factors, implementation hurdles and benefits accrued by these industries as a result of implementing EMSs. Although enormous benefits have been accrued as a result of EMS implementation, a plethora of hurdles still persist in the realm of EMS implementation in these industries. Against this background, this paper concludes by prescribing a number of recommendations that could be used to promote the implementation of EMSs in industries that interact with the Atlantic coast of Cameroon.
