Restoration and Rehabilitation of Degraded Ecosystems in Arid and Semi-Arid Lands. II. Case studies in Southern Tunisia, Central Chile and Northern CameroonbackgroundThis study compares non-human and human determinants of ecosystem degradation processes in three contrasted regions, as well as interventions tested in each. The three responses to ecosystem degradation under review are restoration, rehabilitation and reallocation as applied to ongoing projects in arid mediterranean region of southern Tunisia, the semi arid tropical savannas of northern Cameroon.

Reforesting the Sahel: Farmer Managed Natural RegenerationBackgroundThis study describes the development of a simple income generating and self-promoting reforestation system called Farmer Managed Natural Regeneration (FMNR) developed in Maradi, Niger. FMNR is an agroforestry system based on the natural regeneration and management of tree systems from underground stumps. Open access copy available |
Farmer Managed Natural Regeneration: The Niger ExperienceBACKGROUNDThis paper reviews the farmer managed natural regeneration (FMNR) program introduced in the Maradi region of Niger around 1983 to restore degraded parts of the lands. FMNR was started in response to past failures of restoration projects that were modeled for temperate climates and in societies and cultures different from those in West Africa. This prompted the use of more conventional traditional methods of regeneration from re-sprouts of felled trees without running expensive nurseries. Open access copy available |
Effect of Exotic Tree Plantations and Site Management on Plant DiversityBackgroundIn this study of species richness, species behavior and stand parameters were analyzed under fast growing exotic tree plantations and compared with the characteristics of nearby secondary forest patches in Pointe-Noire and Loudima in Congo. The plantations were established in a grass-dominated vegetation of native savanna. The planted species investigated were mainly eucalypts hybrid (PF1), and secondarily Acacia auriculiformis and Pinus caribaea. Open access copy available |
The Savanna Tree Acacia polyacantha Facilitates the Establishment of Riparian Forests in Serengeti National Park, TanzaniabackgroundThis study tests if stands of Acacia polyacantha facilitate the establishment of forest trees by examining the distribution, growth, and survival of juvenile forest trees. The influence of stand size, locations within the stand, presence of canopy trees, competition from grasses, effects of fires and effects of thorny shrubs on herbivore exclusion and conditions for establishment of A. polyacantha in grasslands were examined in Serengeti National Park of Tanzania.

18 Secondary Forests in West Africa: A Challenge and Opportunity for ManagementbackgroundThis chapter discusses the importance and threats to secondary forests in West Africa, and the description of the floristic diversity and forest succession in secondary forest ecosystems. In addition, silvicultural and complementary management systems and the opportunities and challenges related are also discussed. Open access copy available |
The Socio-Economic Effects of Ghana's Government Afforestation Project on Beneficiary Farmers in the Dormaa District of the Brong Ahafo region of GhanaBackgroundForests play a central role in Ghana's global economy and local livelihoods, yet degradation and overharvesting continue to be an issue. In response, the Ghana government implemented an afforstation program in 2001 to restock forests and help alleviate poverty. Open access copy available |
Effect of Nursery Practices on Seedling Survival and Growth of Selected Miombo Tree Species, Morogoro, TanzaniabackgroundThis study investigates the effects of shade, polythene tube diameter and height, and soil mixtures on seedling survival and growth of five Miombo tree species in Morogoro, Tanzania. Research Goals & MethodsFor each species, two nursery experiments were carried out. That is a) degree of shading, pot diameter and height trial, which adopted a split-split plot design with three replications and b) nursery soil mixtures adopted a completely randomized block design with three replications.
