Promoting the consumption of forest plant foods is a sustainable way of ensuring good nutrition and food security. This study assessed traditional knowledge on and use of forest plant foods in three administrative districts of Ghana and evaluated their potentials for domestication and processing. A total of 606 households were randomly selected and interviewed using enumerator-administered questionnaires.
This report entitled "Forest and Water on a Changing Planet: Vulnerability, Adaptation and Governance Opportunities" presents the outcomes of the sixth global scientific assessment undertaken in the framework of GFEP. The report reflects the importance of integrated action towards ensuring access to water for all and sustaining life on land. The provision of clean water is the most basic ecosystem service necessary for life on earth.
In 2014, the Government of Ethiopia requested the UN-REDD Programme to support the country in assessing the contribution of forest ecosystems to national income in the context of the national REDD+ process. The contribution of forest ecosystems to national income is seen as a vital element of the case for forest conservation in Ethiopia. Prior to this study, no full assessment of the income derived from forest-derived goods and services had been. By assessing the full contribution of forests to market and non-market income, a more complete picture of their economic importance emerged.
This publication analyses whether increased efficiency in forestry operations and forest product processing and utilization are interesting REDD+ policies and measures for the Government of Kenya to pursue, with the potential to attract public and/or private investments to enable REDD+ implementation. In particular, the report focuses on the extent to which efficiency improvements could address supply deficiency in the forest sector, thereby reducing pressures on existing forests and related emissions.
Ce document définit la dynamique forestière en Côte d'Ivoire par télédétection concernant trois années pivot (1986, 2000, 2015) en Côte d'Ivoire. Les résultats de cette étude montrent que la couverture forestière a fortement régressé de 1986 à 2015 (7 850 864 ha en 1986, 5 095 452 ha en 2000 et 3 401 146 ha en 2015). Les taux annuels de déforestation sont de 3,04 % sur la première période et de 2,66% sur la seconde période. Les forêts de la Côte d'Ivoire ont ainsi presque disparues en dehors du Parc National de Tai et la réserve de N'zo.
Ce livre nous emmène au coeur des zones de forêts denses et sahéliennes de l'Afrique centrale, un écosystème précieux et essentiel à la vie quotidienne de ses habitants, représentant l'un des trois principaux ensembles boisés tropicaux de la planète. Dix pays (Burundi, Cameroun, Congo, Gabon, Guinée Equatoriale, République Centrafricaine, République Démocratique du Congo, Rwanda, Sao Tomé & Principe, Tchad) abritent ces forêts et savanes, riches d'importantes ressources naturelles.
Living in and from the forests of Central Africa is intended first and foremost as a full-scale extension tool concerning NWFPs in Central Africa. It is a work on the groups who have always lived in these forests, forests that contribute to every aspect of their daily lives, both material and spiritual, and enable them to survive even in periods of extreme crisis. http://www.fao.org/documents/card/en/c/b4e5bb79-0a8a-45fa-b2bf-a5e97183e94a/
Farm forestry has proved to be an important enterprise for small- and large-scale farmers worldwide. It has the potential of improving forest/tree cover across the globe. In Kenya, the forest cover is less than 2%. The country envisions achieving 10% forest cover over the next decade through promotion of farm forestry. However, the decision to plant trees on farmers’ land could be difficult. The study aimed to analyze the determinants of tree retention on farm for improvement of forest cover. Stratified and simple random sampling techniques were used in selecting 209 farmers.

The introduction of carbon finance as an incentive in forestry farming has a potential of increasing the amount of carbon sequestered. However, this has created a daunting task among investors in forestry to optimise the joint production of wood and carbon sequestration. For instance, investors might find it profitable to give up some timber returns in exchange for carbon credits. This study evaluated expected income from growing Cupressus lusitanica Mill., Pinus patula Schiede ex Schltdl. & Cham., Eucalyptus saligna Sm. and Juniperus procera Hochst. ex Endl.
Carbon sequestration has become a crucial service forests provide for regulation and mitigation of climate change through reduction of greenhouse gas emissions. In Kenya, Cupressus lusitanica, Pinus patula and Eucalyptus saligna are common exotic plantation species grown in high potential areas. They are characteristerised by fast growth resulting to removal of more carbon dioxide from the atmosphere. However, little has been done in estimating aboveground and belowground carbon of these species.
The main objective of this study was to determine the effect of different temperatures and moisture contents on Cordia simesis seeds viability on storage. Seeds of Cordia sinenis (L) were stored in hermitically corked glass viols for up to 150 days at different constant temperature ranging 60C to 350 C and moisture contents ranging 6% to 18% (fresh weight basis). Seed with different moisture contents were retrieved at intervals of 30 days from different storage temperature regimes for viability for a period of 150 days.
Osyris lanceolata (African Sandalwood) belongs to the family Santalaceae that hosts some of the most valuable species for perfumery oil extraction. In India and Australia, Santalum album and Santalum spicatum are well developed for perfumery oil extraction through establishment of commercial plantations. In Africa, O. lanceolata has attracted significant attention as potential perfumery oils
In East Africa, lepidopteran stemborers such as Chilo partellus and Busseola fusca are major constraints to production of maize, which is the main staple food crop in the region. Cereals depend on silicon (Si)-based defences to fight off herbivores. Using altitudinal ranges in the East African highlands as ecological surrogates for inferring climate change, it was shown that Si concentrations in soil and maize decreased with altitude. This was attributed, in part, to low temperatures at high altitudes, which negatively affected Si assimilation by maize. Experiments showed that B.
Timber species differ in their response to logging disturbance. Knowledge about the impacts of different logging intensities is necessary to determine levels of timber extraction compatible with species responses in order to refine management interventions. We examined the effects of two logging intensities on the abundance and composition of tree seedlings in gaps in Pra Anum Forest Reserve within a Moist Semi-deciduous forest in Ghana.
This paper discusses the digitization of indigenous knowledge on forest foods and medicine for the effective management of Ghana’s forest resources. The paper is based on a survey conducted in nine communities in Ghana where primary data were obtained from 606 respondents using in-depth face-to-face interviews. The aim of the study was to assess what knowledge local communities had about products of the forest especially indigenous forest foods and medicine. The findings reveal that local communities have an in-depth knowledge of indigenous forest foods and medicines.
An online Glossary of Wildlife Management Terms and Definitions was initiated by the Collaborative Partnership on Sustainable Wildlife Management (CPW) and compiled by the International Union of Forest Research Organizations (IUFRO) together with the CPW members in order to raise awareness of the diverse usage and meanings of technical terms related to wildlife management and conservation.
IUFRO launched a new policy brief on forest landscape restoration at COFO23 World Forest Week hosted at the United Nations Food and Agriculture Organization in Rome, Italy.
Restoring Forest Landscapes: A "Win-Win" for People, Nature and Climate outlines key messages for policy makers, synthesizing major lessons learnt from a recent review of the state-of-the-art scientific knowledge on the climate benefits of forest landscape restoration (LFR).
Allanblackia species are high value multipurpose indigenous fruit trees whose seeds contain edible oil that has become a foreign exchange earner for rural-based enterprises. Wild harvesting could not sustain the supply to industry and therefore domestication was focused on developing propagation techniques, selecting and collecting elite planting materials. Little emphasis was placed on the soil nutrient requirements where preliminary results showed seedlings grown in rhizosphere soil of wild trees had good growth performance.
Forest encroachment into savanna is occurring at an unprecedented rate across tropical Africa, leading to a loss of valuable savanna habitat. One of the first stages of forest encroachment is the establishment of tree seedlings at the forest–savanna transition. This study examines the demographic bottleneck in the seedlings of five species of tropical forest pioneer trees in a forest–savanna transition zone in West Africa.
The impacts of charcoal production on woodland were assessed in the Forest-Savannah Transition Zone of Ghana to facilitate policy formulation for a win-win situation for both sustainable woodland management and charcoal production. Twenty-three harvested sites in two charcoal producing communities were assessed in terms of the extent of harvested sites, changes in biomass carbon stock and tree basal area.
