African Farm/Family Forestry and Producer Organizations for improved livelihoods and sustainable landscape management
The paper tries to provide answers to questions on the status of farm/family forestry in Africa
in terms of opportunities and challenges, their contribution to economic development and
sustainable landscape management. In the paper, highlights are made on issues related to land tenure, institutional settings and other supporting policies. In addition, market access and factors that may influence the development of forest products value chains are discussed alongside the possibilities for promoting and strengthening cohesive actions amongst FFPOs in different countries and regions. Answers are provided on questions related to easiness to group formation and registration and their product base. Examples of such groups in terms of associations or federations at local, national and regional levels alongside some examples are briefly described. Information on how FFPOs are currently helping forestry farmers are provided with some examples clearly started including their future potentials and/or pitfalls. At the end of the paper, the outlook in the coming 5 to 10 years for the main opportunities and challenges awaiting farm/family forestry and related FFPOs in Africa are pinpointed
Effects of credit constraints on the productivity of small and medium-sized enterprises in Cameroon
This paper assesses the determinants and effects of credit constraints on the productivity of small and medium-sized enterprises (SMEs) in Cameroon. Use is made of the Cameroon enterprise survey data collected by the World Bank in 2009 and an endogenous switching regression model. Results show that interest rates, size of enterprise, size of loan, size of collateral, maturity of loans and legal status of enterprises are major sources of credit constraints faced by SMEs. Results also indicate that medium enterprises are more credit constrained than small enterprises; meanwhile the effects of credit constraints affect small enterprises more than medium enterprises. Credit constrained firms have lower levels of productivity relative to unconstrained firms. These results have implications for the creation of credit bureaux, prudential stringency and rationalization of the Cameroon tax system
Nutrient and bioactive analyses of forests foods for policy making on food and nutrition security in Central Africa
A serious public health challenge may be envisaged in central Africa, especially with a growing population, rapid westernization of traditional African diets and increasing demand for sufficient essential nutrients and bioactive compounds. However, having the second largest tropical rainforest basin in the world, forest foods that are widely consumed in Central Africa contain adequate essential nutrients such as carotenoids, flavonoids, proanthocyanins, polyphenols, vitamins C and E, Fe, Se, Ca and Na. This review purports that forest foods can considerably contribute towards meeting human nutrient requirements by replacing imported western foods that are generally more expensive and lower in essential nutrients. We recommend that forest foods should be considered in setting nutrition education strategies and formulating policies governing food and nutrition security in Central Africa

Nutrients and bioactive compounds content of Baillonella toxisperma, Trichoscypha abut and Pentaclethra macrophylla from Cameroon
Baillonella toxisperma, Pentaclethra macrophylla and Trichoscypha abut are important foods for communities living around forests in Cameroon. Information on the nutritional value and bioactive content of these foods is required to establish their contribution to the nutrition and health of the communities. Samples of the three foods were obtained from four villages in east and three villages in south Cameroon. The foods were analyzed for proximate composition, minerals and bioactive content using standard chemical analysis methods. T. abut was found to be an excellent source of bioactive compounds; flavonoids (306 mg/100 g), polyphenols (947 mg/100 g), proanthocyanins (61.2 mg/100 g), vitamin C (80.05 mg/100 g), and total oxalates (0.6 mg/100 g). P. macrophylla was found to be a rich source of total fat (38.71%), protein (15.82%) and total fiber (17.10%) and some bioactive compounds; vitamin E (19.4 mg/100 g) and proanthocyanins (65.0 mg/100 g). B. toxisperma, was found to have high content of carbohydrates (89.6%), potassium (27.5 mg/100 g) and calcium (37.5 mg/100 g). Flavonoids, polyphenols, vitamins C and E are the main bioactive compounds in these forest foods. The daily consumption of some of these fruits may coffer protection against some ailments and oxidative stress. Approximately 200 g of either B. toxisperma or P. macrophylla, can supply 100% iron and zinc RDAs for children aged 1–3 years, while 300 g of the two forest foods can supply about 85% iron and zinc RDAs for non-pregnant non-lactating women. The three foods provide 100% daily vitamins C and E requirements for both adults and children. The results of this study show that Baillonella toxisperma, Pentaclethra macrophylla and Trichoscypha abut can considerably contribute towards the human nutrient requirements. These forest foods also contain substantial levels of health promoting phytochemicals notably flavonoids, polyphenols, vitamins C and E. These foods therefore have potential to promote nutrition and health, especially among forest dependent communities who consume them in substantial amounts
Evaluation of the contribution of NTFPs gathering: to rural people’s livelihoods around two timber concessions in Gabon
NTFP are often presented as bringing a major contribution to rural livelihoods in terms of food and cash, and this particularly for rural communities. Few data are available in Gabon to confirm this common assertion. An annual monitoring of 127 households was conducted in 14 villages around two timber concessions in the south-east and south-west regions of Gabon. Conventional socio‐economic survey tools such as focus group discussions, census and semi-structured interviews of households were used in gathering data during one year. Results reveal that rural people depend on various sources of livelihoods for food and income generation, but overall, the current contributions of vegetal NTFPs are insignificant compared to other activities. Odika (Irvingiagabonensis), atanga sauvage (Dacryodes buettneri), fungus (Termitomyces spp) and “nut” (Coula edulis) represent the main forest products that are commonly harvested by rural people, primarily for subsistence purposes while the surplus is sold. Although some efforts were made to promote the NTFP sector in the country, the results of this study suggest that: (1) the main components of the decree No.137/PR/MEFP of February 4, 2009, that prohibited the logging of five multiple use tree species over a period of 25 years should be reconsidered for revision; (2) the State authorities and partners should promote projects aiming at increasing the knowledge of the NTFP sector. These projects should contribute to the census of NTFP (for food, medicine and services), characterize their uses, the market chains of target products, and the development potential of NTFP. Such projects may help Gabon and other Congo Basin countries to fix norms/standards for a sustainable natural resource management and for enhancing their contribution to the national economy. This will be particularly relevant in the light of dwindling oil revenues and the need to diversify and promote other revenue sources in the country
Холистичность и преодоление дуализма в философии К.Г. Юнга и квантовой физике
В наше время начинает складываться целостное, холистическое мировидение. Оно формируется, с одной стороны, самим естествознанием в его стремлении обрести единство, с другой – науками о человеке.
