Plantation Forestry in Sub Saharan Africa: Silvicultural, Ecological and Economic Aspects

BACKGROUND

Plantation forestry in Africa is practiced using exotic species to supply timber and non- timber forest products, which are for industrial and non- industrial purposes. Ownership of the plantations extends from governments and large industrial corporations to individual farmers. Private plantations are performing well, with a better supply compared to the public ones. Plantation programs in Africa have undergone various challenges leading to a decline in production in the past two decades.

Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, Nigeria

Background

Since more than 98% of Nigeria’s current economic support is crude oil, and oil spills are in inevitable and frequent, six treatment sample-cell were tested on the soils of the Niger Delta of Nigeria for crude oil bioremediation. Oil spills cause nitrogen levels to decrease, while increasing carbon content. A decrease in nitrogen and the toxicity of crude oil reduces the growth of heterotrophic bacteria, which utilize petroleum carbon for cell synthesis.

Régénération naturelle assistée: Gestion des arbres champêtres au Sahel (Assisted natural regeneration: management of wild trees in the Sahel)

The authors outline threats to forest regeneration in the Sahel, particularly with regard to agroforestry systems. Better agroforestry practices that incorporate assisted natural regeneration would allow for more sustainable availability of firewood and productivity of agroforestry systems. The authors strongly advocate for major changes in behavior and politics, including decentralization of authority over forest resources.

Explorer la banque de graines du sol pour mieuxcomprendre la dynamique de régénération des forêtstropicales africaines (synthèse bibliographique)

The authors provide a review of the current knowledge of soil seed banks in African tropical forests. They argue that increased knowledge of soil seed banks will lead to better understanding of forest regeneration and therefore more successful reforestation efforts. Finally, the authors call for better characterization of seed banks based on forest community, as this could aid reforestation and sustainable forest management efforts in African tropical forests.

Mangrove Ecosystem Recovery and Restoration from Oil Spill in the Niger Delta: The GIS Perspective

Background

In Nigeria, Mangrove's provide critical environmental and economic services, including maintaining water quality, serving as breeding grounds for important fish and crustacean, and as a source of food and materials.  Yet, the country also has a history of oil spills that threaten these important ecosystems. In order to understand the effects of oil spills on mangroves, this study examines the land cover change of mangrove ecosystems in the Niger Delta between 1986 and 2008.

Effect of Taungya on Regeneration of Endemic Forest Tree Species in Nigeria: Edo State Nigeria as a Case Study

background

This study aims to investigate the number of native species that can regenerate under natural conditions in a 3-year Taungya system in Edo State, Nigeria. Taungya is an agroforestry system that combines forestry practices with agriculture and agriculture-related activities.

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.
