Impact of Forest Management on Insect Abundance and Damage in a Lowland Tropical Forest in Southern CameroonBackgroundA burgeoning timber industry in Cameroon, which became the fifth largest producer of timber in the world in the 1990’s, led to unsustainably high deforestation rates and high demand for forest regeneration interventions. Research in the Mbalmayo Forest Reserve in southern Cameroon has compared different silvicultural techniques for forest regeneration including complete and partial clearance methods.

Fuelwood collection and its impacts on a protected tropical mountain forest in Uganda.Background This study examined the patterns, effects and potential management of fuelwood extraction on the forest of Mt Elgon, located in the Eastern part of Uganda, Sub- Saharan Africa. Fuelwood is the main source of energy, mainly collected from the forest. 98% of the households use fuelwood and charcoal for cooking and heating. This is a protected area with a history of conflict between surrounding populations and conservation actors. No other forest remains in its direct vicinity.Research goals and Methods Available with subscription or purchase |
Floristic composition, structure and natural regeneration in a moist semideciduous forest following anthropogenic disturbances and plant invasionBackgroundThis research examined the floristic composition, struture and natural regeneration in three different forests: undisturbed (UF), disturbed-invaded (DIF) and disturbed (DF) within a forest reserve in Ghana.

Targeted habitat restoration can reduce extinction rates in fragmented forestsBackgroundHabitat lost is one of the primary drivers of species extinction. This study examines two highly-fractured ecosystems, the Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil, and evaluates the rate at which habitat loss may lead to extinction and thus biodiversity loss. Specifically, the authors use halflife vs. area relationship to determine how long it will take to lose one-half of all tropical bird communities in each habitat. Open access copy available |
Restoration of Ecosystem Carbon Stocks following Exclosure Establisment in Communal Grazing Lands in Tigray, EthiopiaBackgroundThe study examines changes in ecosystem Carbon stocks (ECS) after the establishment of exclosures on communal grazing lands. Exclosures are areas where livestock are prohibited from grazing. Available with subscription or purchase |
Sprouting, succession and tree species diversity in a South African coastal dune forestBackgroundThis study examines the role of sprouting in the maintenance of plant diversity where prevailing disturbance frequency and severity allows, specifically, in the coastal dune forest of Kwazulu-Natal.

Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, NigeriaBackgroundSince 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. Available with subscription or purchase |
Getting the Right End of the Stick: Participatory Monitoring and Evaluation in an Organizational ContextBackgroundThis chapter documents the process by which CARE Zambia institutionalized a learning approach to their internal management and a participatory model of monitoring and evaluation as well as the results of this transition, using a food security project as a case study. CARE Zambia used seven principles to turn themselves into a 'learning organization': 1) thrive on change, 2) facilitate learning from the surrounding environment, 3) facilitate learning from staff, 4) encourage experimentation, 5) communicate sucesses and failures, 6) reward learning, and 7) promote a sense of caring.

Abreha Weatsbeha Community Ethiopia: Equator Initiative Case Studies. Sustainable Development Solutions for people, nature and resilient communitiesBackgroundThis report from UNDP is intended to "the the full story ofhow (innovative sustainable developments solutions) evolve,the breadth of their impacts (and) how they change over time" through the case study of Abreha we Atsbeha in Ethiopia. Out of 800 contestants, the community in Abreha we Atsbeha was awarded the Equator Prize in along with US$20,000 in 2012 in recognition of their tremendous work on the restoration of degraded land and subsequent increases in food security, nutrition, and local livelihoods.
