The Woods of Liberia
THE WOODS OF LIBERIA October 1959 No. 2159 UNITED STATES DEPARTMENT OF AGRICULTURE FOREST PRODUCTS LABORATORY FOREST SERVICE MADISON 5, WISCONSIN In Cooperation with the University of Wisconsin THE WOODS OF LIBERIA1 By JEANNETTE M. KRYN, Botanist and E. W. FOBES, Forester Forest Products Laboratory,2 Forest Service U. S. Department of Agriculture - - - - Introduction The forests of Liberia represent a valuable resource to that country-- especially so because they are renewable. Under good management, these forests will continue to supply mankind with products long after mined resources are exhausted. The vast treeless areas elsewhere in Africa give added emphasis to the economic significance of the forests of Liberia and its neighboring countries in West Africa. The mature forests of Liberia are composed entirely of broadleaf or hardwood tree species. These forests probably covered more than 90 percent of the country in the past, but only about one-third is now covered with them. Another one-third is covered with young forests or reproduction referred to as low bush. The mature, or "high," forests are typical of tropical evergreen or rain forests where rainfall exceeds 60 inches per year without pro longed dry periods. Certain species of trees in these forests, such as the cotton tree, are deciduous even when growing in the coastal area of heaviest rainfall, which averages about 190 inches per year. Deciduous species become more prevalent as the rainfall decreases in the interior, where the driest areas average about 70 inches per year. 1The information here reported was prepared in cooperation with the International Cooperation Administration. 2 Maintained at Madison, Wis., in cooperation with the University of Wisconsin. -
GEF Prodoc TRI Cameroon 28 02 18
International Union for the Conservation of Nature Country: Cameroon PROJECT DOCUMENT Project Title: Supporting Landscape Restoration and Sustainable Use of local plant species and tree products (Bambusa ssp, Irvingia spp, etc) for Biodiversity Conservation, Sustainable Livelihoods and Emissions Reduction in Cameroon BRIEF DESCRIPTION OF THE PROJECT The Republic of Cameroon has a diverse ecological landscape, earning her the title “Africa in Miniature”. The southern portions of Cameroon’s forests are part of the Congo Basin forest ecosystem, the second largest remaining contiguous block of rainforest on Earth, after the Amazon. In addition to extensive Mangrove belts, Cameroon also holds significant portions of the Lower Guinea Forest Ecosystems and zones of endemism extending into densely settled portions of the Western Highlands and Montagne forests. The North of the country comprising the Dry Sudano-Sahelian Savannah Zones is rich in wildlife, and home to dense human and livestock populations. Much of the population residing in these areas lives in extreme poverty. This diversity in biomes makes Cameroon one of the most important and unique hotspots for biodiversity in Africa. However, human population growth, migrations, livelihoods strategies, rudimentary technologies and unsustainable land use for agriculture and small-scale forestry, energy and livestock, are contributing to biodiversity loss and landscape degradation in Cameroon. Despite strong institutional frameworks, forest and environmental policies/legislation, and a human resource capital, Cameroon’s network of biomes that include all types of forests, tree-systems, savannahs, agricultural mosaics, drylands, etc., are progresively confronted by various forms of degradation. Degradation, which is progressive loss of ecosystem functions (food sources, water quality and availability, biodversity, soil fertility, etc), now threatens the livelihoods of millions of Cameroonians, especially vulnerable groups like women, children and indigenous populations. -

This article scrutinizes the functioning of the CFA, considering the role the currency has in persistent underdevelopment in most of Francophone Africa. In doing so, the article identifies the CFA as the most blatant example of functioning neocolonialism in Africa today and a critical device that promotes dependency in large parts of the continent. Mainstream analyses of the technical aspects of the CFA have generally focused on the exchange rate and other related matters. However, while important, the real importance of the CFA franc should not be seen as purely economic, but also political. -
What Happened to the Forests of Sierra Leone?
land Article What Happened to the Forests of Sierra Leone? Richard A. Wadsworth 1,* and Aiah R. Lebbie 2 1 Department of Biological Sciences, Njala University, Njala, Sierra Leone 2 National Herbarium of Sierra Leone, Department of Biological Sciences, Njala University, Njala, Sierra Leone; [email protected] * Correspondence: [email protected]; Tel.: +232-(0)-79-675-004 Received: 28 March 2019; Accepted: 1 May 2019; Published: 9 May 2019 Abstract: The last National Forest Inventory of Sierra Leone took place more than four decades ago in 1975. There appears to be no legal definition of “forest” in Sierra Leone and it is sometimes unclear whether reports are referring to the forest as a “land use” or a “land cover”. Estimates of forest loss in the Global Forest Resource Assessment Country Reports are based on the estimated rate during the period 1975 to 1986, and this has not been adjusted for the effects of the civil war, economic booms and busts, and the human population doubling (from about three million in 1975 to over seven million in 2018). Country estimates as part of the FAO (Food and Agriculture Organization of the United Nations) Global Forest Assessment for 2015 aggregate several classes that are not usually considered as “forest” in normal discourse in Sierra Leone (for example, mangrove swamps, rubber plantations and Raphia palm swamps). This paper makes use of maps from 1950, 1975, and 2000/2 to discuss the fate of forests in Sierra Leone. The widely accepted narrative on forest loss in Sierra Leone and generally in West Africa is that it is rapid, drastic and recent. -
Carbon Flow Pattern in the Forest Zones of Nigeria As Influenced by Land Use Change

Adesina 2 1Centre for Energy Research and Development (CERD), Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. 2Department of Geography, Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. Accepted 15 July, 2011 Forest in Nigeria plays a much wider role in the overall balance of issues affecting the country than those of climate change alone. Nigeria’s tropical forest is depleting fast, due largely to uncontrolled human activities. Poverty, urbanization, population growth and insecurity are the major causes of this trend. Tracking carbon flow in these forest life zones will help account for the effect of these activities on the environment. COPATH, an acronym for Total Carbon Flow from Conversion to Agriculture, Pasture, Harvest and OTHER land-uses including construction of dams, roads, forest fires and human settlement, etc., was used for tracking carbon flow in the forest zones. From the five forest life zones, total carbon stored was estimated to be 2.55 TgC. The four activities of agriculture, harvest, pasture and bush burning were pronounced in contributions to land use changes, particularly to forest depletion. In this paper it is shown that carbon emission was highest from harvesting activity in year 2000, principally from clear-cutting activity in the lowland rainforest as against that of 1990 study, which showed agricultural activity as the major anthropogenic activity leading to carbon release into the atmosphere. -

Box 2012, Democratic Republic of Congo (DRC); [email protected] * Correspondence: [email protected] Received: 22 December 2019; Accepted: 20 March 2020; Published: 7 April 2020 Abstract: Humid conditions and equatorial forest in the Congo Basin have allowed for the maintenance of significant biodiversity and carbon stock. The ecological services and products of this forest are of high importance, particularly for smallholders living in forest landscapes and watersheds. Unfortunately, in addition to deforestation and forest degradation, climate change/variability are impacting this region, including both forests and populations. We developed three case studies based on field observations in Cameroon, the Central African Republic, and the Democratic Republic of Congo, as well as information from the literature. Our key findings are: (1) the forest-related water cycle of the Congo Basin is not stable, and is gradually changing; (2) climate change is impacting the water cycle of the basin; and, (3) the slow modification of the water cycle is affecting livelihoods in the Congo Basin. -

Geography, Demography, and Economic Growth in Africa
DAVID E. BLOOM Harvard Institute for International Development JEFFREY D. SACHS Harvard Institute for International Development Geography, Demography, and Economic Growth in Africa THE POVERTY of sub-Saharan Africa is one of the most obdurate features of the world economy. Since the industrial revolution, this has been the world's poorest and also its most slowly growing region. The most reliable estimates of world and regional gross domestic products for the period 1820-1992 are those prepared by Angus Maddison.1 Figure 1 shows estimated long-term growth profiles for selected regions. Ac- cording to these estimates, sub-Saharan Africa (hereafter, Africa) began the modern era at approximately one-third of the income level of the richest region at that time, Western Europe. In 1992 it had approxi- mately one-twentieth of the income level of the richest region, Maddi- son's "western offshoots," which includes the United States, Canada, Australia, and New Zealand. Maddison estimates that Africa's per cap- ita income in 1992 was approximately that of Western Europe in 1820: This paper has benefited from work done under several research programsat the HarvardInstitute for InternationalDevelopment, including those on economic geography and development, populationand reproductivehealth, and African economic develop- ment.

Influence of the Gulf of Guinea Coastal and Equatorial Upwellings on the Precipitations Along Its Northern Coasts During the Boreal Summer Period

The coastal upwelling has a real impact on the local yet documented biological resources. However, climatic impact studies of this seasonal upwelling are paradoxically very rare and disseminated and this impact is still little known, especially on the potential part played by the upwelling onset on the regional precipitation in early boreal summer. This study shows that coastal precipitations of the July-September period are correlated by both the coastal and equatorial sea-surface temperatures (SSTS). This correlation results in a decrease or a rise of rainfall when the SSTs are abnormally cold or warm respectively. The coastal areas that are more subject to coastal and equatorial SSTs influence are located around the Cape Three Points, where the coastal upwelling exhibits the maximum of amplitude.
