Promoting Stewardship of Forests in the Humid Forest Zone of Anglophone West and Central Africa Promoting Stewardship of Forests in the Humid Forest Zone of Anglophone West and Central Africa FINAL REPORT of a collaborative research project undertaken by The United Nations Environment Programme and The Center for International Forestry Research Project co-ordinators and editors of the final report: Dennis P. Dykstra Center for International Forestry Research Godwin S. Kowero Center for International Forestry Research Albert Ofosu-Asiedu Forest Research Institute of Ghana Philip Kio Forestry Consultant, Nigeria Copyright © 1996 Center for International Forestry Research (CIFOR) Published by Center for International Forestry Research (CIFOR) P.O. Box 6596 JKPWB Jakarta 10065 Indonesia with support from The United Nations Environment Programme Nairobi, Kenya ISBN 979-8764-09-9 ii PREFACE Sustainable forestry development combines the concepts of economic growth and environ- mental conservation; as such it is reasonable to expect it be on the agenda of many national and international organisations dealing with economic development and environmental conserva- tion. The United Nations Environment Programme (UNEP) is one such organisation which gives attention to sustainable forestry development in the context of the United Nations Con- ference on Environment and Development. Agenda 21 gives UNEP a comparative advantage in placing its activities at the interface of the integration of environment and development. It is in this context that UNEP conceived the project whose results are reported in this docu- ment, with the Center for International Forestry Research (CIFOR) as the collaborating partner responsible for the project’s implementation. The project focuses on the West African humid forests of Ghana and Nigeria, with information provided on Liberia and Sierra Leone to the extent possible. Cameroon, a country which is officially Francophone but with a large English- speaking population, has been included in the study in order to provide more complete cover- age of Anglophone West African countries where this type of forest exists. The general objective of the project was to integrate all available information on West African humid forest formations in order to catalyse initiatives at national, regional and international levels which may foster the adoption of sustainable forest management principles throughout the region. The project reported here will contribute to a larger joint project currently being undertaken by CIFOR and the Government of France for the Francophone countries of Côte d’Ivoire, Cam- eroon, Central African Republic, Congo and Gabon. An Advisory Group composed of representatives from CIFOR, UNEP, ATO, FAO, ITTO, and several national institutions and NGOs helped oversee the project. UNESCO and IUCN were also invited to join the Advisory Group but were not able to do so, although they were kept informed about the project and its progress. Field work was contracted to the Forest Research Institute of Ghana (FORIG) under the direction of Dr. Albert Ofosu-Asiedu, and to Prof. Philip Kio of Nigeria. Under their direction a synthesis was prepared to summarise forest man- agement technologies and options in the region. They also organised thematic workshops which evaluated land use practices and related policies, institutional arrangements, and other forms of government intervention which affect sustainable forest management. Additional workshops examined inter-generational issues and technical forest management issues. A stakeholders’ consultation was also convened to obtain the views of various stakeholder groups. The present report is a product of all these efforts. The report is organised into nine chapters. The first chapter gives an account of the forestry situation in West and Central Africa, with emphasis on vegetation distribution and factors af- fecting forest management. Chapters 2 and 3 highlight past and present silvicultural and forest management practices and also consider management control systems. The relevance of biodi- versity and the role of non-timber forest products are explored in Chapter 4. Intergenerational issues, socio-economic factors influencing sustainable forest management, and the iii Promoting Forest Stewardship in West and Central Africa relevance of policies and legislation are addressed in Chapters 5, 6 and 7. Chapter 8 outlines strategies and incentives which might be adopted to promote sustainable forest management. The report concludes in Chapter 9 with suggestions for research which could be undertaken to fill gaps in knowledge which became apparent in the course of this project. In the hope of maximising its utility to foresters, environmentalists, government decision mak- ers and other interested parties throughout the tropics, this report is being published simulta- neously in both English and French. Copies of the publication will be available without charge from both UNEP and CIFOR until supplies are exhausted. ACKNOWLEDGEMENTS The research summarised in this report was made possible by funding from UNEP’s Environ- ment Fund, with additional support provided by CIFOR. Essential contributions were also made by the Project Advisory Group, numerous scientists from FORIG, consultants who pre- pared background papers for the workshops, and all who participated in the various work- shops. These contributions are gratefully acknowledged. Finally, Dr. Robert Nasí, leader of FORAFRI (a joint CIFOR/CIRAD-Forêt research project focusing on sustainable forest man- agement in Francophone West Africa and supported by the Government of France), very gra- ciously agreed to check this entire document for accuracy. His efforts are very much appreci- ated, but any errors which remain are those of the Editors.

  • 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.

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.

OE HUDRED YEARS OF FORESTRY I GHAA: A REVIEW OF POLICY AD REGULATORY DISCOURSES O TIMBER LEGALITY K. A. Oduro 1, E. Marfo 1, V. K. Agyeman 1 and K. Gyan 2 1CSIR-Forestry Research Institute of Ghana, University Post Office Box UP 63, KUST, Kumasi Ghana 2Ministry of Lands and atural Resources, Accra Ghana Email: [email protected] ; [email protected] ABSTRACT Ghana has seen incremental shifts in forest policy, legislation and management approaches in the last one hundred years. Information on forests through time and knowledge of policy evolution, laws, and participants and institutions involved in the policy process is important to deal with complexities associated with timber legality and trade. This paper reviews the evolution of forest policies and regulations on timber legality in Ghana using a historical discourse analysis. It characterises the regulatory discourses of successive forest policies and legislations and the extent to which policy and policy instruments, particularly on trade of legal timber, reflect the hard, soft, and smart regulatory discourses. The paper shows that until the mid-1980s Ghana’s timber regulation policies had been characterized largely by state control using top-down management and hard law regulations. The mid- 1980s and the early 1990s represent an interface between the softening of state control and the emergence of de-regulation and soft law discourses. The 1994 Forest and Wildlife Policy reflected this interface calling for improved collaboration with communities and market-driven strategies to optimize forest use.

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.
