Restoration and Rehabilitation of Arid and Semiarid Mediterranean Ecosystems in North Africa and West Asia: A ReviewbackgroundThis study systematically analyzes extensive literature on exclosures, afforestation, reafforestation, rehabilitation and other regeneration operations over several million hectares. It also includes 50 years of the author’s personal field experience in 17 of the 20 Mediterranean bioclimatic areas from the Atlantic Ocean to the Aral Sea. Available with subscription or purchase |

Ecología experimental y ecofisiología: bases para el uso sostenible de los recursos naturales de las zonas áridas neo-tropicales (Experimental ecology and ecophysiology in dry tropical forests)El autor recoge los resultados más relevantes que han permitido la resolución de algunos problemas de producción vegetal, que pueden ser utilizados como herramientas fundamentales de planificación para la producción en las tierras secas en el noroeste Venezuela. Las condiciones edáficas y climáticas que caracterizan las zonas áridas y semiáridas tropicales las colocan entre los ecosistemas más frágiles del mundo y más susceptibles a la desertificación.

Establishment of Broad-leaved Thickets in Serengeti, Tanzania: The Influence of Fire, Browsers, Grass Competition, and ElephantsBackgroundIn Tanzania, thickets are declining due to frequent fires yet when the fires are removed the thickets fail to regrow. As a fire-resistant tree, seedlings of E. divinorum are potentially an ideal species to restore these land covers. Available with subscription or purchase |
Effects of Canopy Cover and Understory Environment of Tree Plantations on Richness, Density and Size of Colonizing Woody Species in Southern EthiopiabackgroundThis study investigates the effects of canopy characteristics and associated understory environmental factors of tree plantations on native woody species colonization in two broadleaved and two coniferous plantations in southern Ethiopia. The plantation forests investigated are surrounded by dry Afromontane natural forest. Available with subscription or purchase |
The Savanna Tree Acacia polyacantha Facilitates the Establishment of Riparian Forests in Serengeti National Park, TanzaniabackgroundOpen access copy available |
Restoration of Dry Afromontane forest using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidataBackgroundShrubs are often considered competitive barriers for seedlings planted in reforestation programs, although they can facilitate tree recruitment, especially in ecosystems under high abiotic stress. An alternative reforestation technique using pioneer shrubs as nurse-plants for Olea europaea ssp. cuspidata was tested in exclosures in northern Ethiopia. Open access copy available |
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 |
Involving Local Farmers in Rehabilitation of Degraded Tropical Forests: Some Lessons from GhanabackgroundThis study is an analysis of a community-based tree planting project in Ghana using the taungya systems with indigenous trees. The project was sponsored by the Forestry Research Institute of Ghana (FORIG), the government of Ghana, and the International Tropical Timber Organization (ITTO). The goal of the tree planting in the project was to improve forest rehabilitation as well as local livelihoods. Available with subscription or purchase |
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.

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.

Plan Vivo, Restoration of degraded ecosystems in the Sahel Burkina FasoBackgroundThis project plans to restore and maintain the Sahelian woodland in northern Burkina Faso by working closely with communities of farmers whose livelihoods are dependent. Open access copy available |
Farmer Managed Natural Regeneration: The Niger ExperienceBACKGROUNDOpen access copy available |
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 |
