ABSTRACT The capacity to promote sustainable use of Non-Timber Forest Products (NTFPs) and facilitate increased financial benefits to local users as incentives for forest conservation is low due to neglect by governments particularly in Nigeria. Such capacity is however imperative to stemming rural poverty and can be enhanced by incorporating NTFP collection and commercialization research into forest management development programs. But sustainable production and conservation of forest produ...
ABSTRACT This study was focused on farmers’ perception of the relevance of technologies generated by research institutes in south-western Nigeria in the area of agroforestry , land evaluation, improved varieties and machinery And equipment. A multistage random sampling technique was used to select the sample size. Two zones were purposively selected (Ogbomoso and Oyo) for they are the food basket of the state. The existing total numbers of farmer groups was obtained (120), out of this; ten...
ABSTRACT The study was undertaken to investigate the influences of flake thickness on physical and mechanical properties of wood cement panel produce from mixed hardwoods species. The properties investigated are modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA), thickness swelling (TS) and linear expansion (LE) of the experimental cement-bonded particleboards. Both the moduli MOR and MOE of specimens were calculated as specified in 'the ASTM Standard No D-1037 of 1...
ABSTRACT The recent trend of demand for cassava provoked by policy support for its production suggests that cassava farmers call increase cassava production (f there are available clean planting materials. Getting standard cassava cuttings by farmers will help them increase their production to meet global cassava competitiveness. However; data on sourcing and use of standard cassava cuttings among farmers is scanty. Sourcing and use of standard cassava cuttings in Egbeda Local Government area...
ABSTRACT This study evaluated the protein fatty acid and mineral changes in sweet potato root iheal inoculated with two selected fungi by solid state fermentation procedure. The total protein content was raised from 4.95% to 11.83% and 6.69% within 48 hrs for Aspergillus oryzae and Aspergillus niger respectively. The total lipid dropped from 1.93% in thè control to 1.36 and 4.19% for A. niger and A. oryzae respectively. The fatty acids 0 6 : 0 and 0 8 :2 were preponderant over other fatty ac...
Abstract Forests are assets that can promote community development and improve household livelihood if sustainably managed. The foremost constraint to sustainable forest management however, is land and in Nigeria, the southeastern (SE) region which is the dominant geographical location of Igboland has the lowest forest cover and available land area for development. This paper therefore reports the prospect of land grant for forestry development activities in the region. Multi-stage sampling ...
ABSTRACT The influences of water pre-treatment temperature and cement/wood mixing ratios on static and moisture response properties of cement-bonded particleboards produced from mixed Nigerian hardwood species were assessed in this study. The process variables for board fabrication were pre-treatment temperature (5 levels) and wood/ cement mixing ratios (5 levels) resulting in 25 treatment combinations in a factorial experiment. The examined properties are modulus of rupture (MaR), modulus of...
ABSTRACT Logging induced damages associated with two different ,harvesting systerns (Conventional Timber Harvesting and Reduced-Impact Logging (RIL» were investigated in 19.84 compartment of Gmelina arborea plantation in Omo Forest Reserve. The same equipment and felling crew were used for both methods. Felling was done using heavy chainsaw (Stihl 070) and skidding was carried out with crawler tractor. The types and severity of damage to the residual stand were determined for felling and sk...
ABSTRACT Toxicity testing of chemicals on animals has been used for a long time to detect the potential hazards posed by chemicals to man. Bioassay technique has been the cornerstone of programmes on environmental health and chemical safety (Ward and Parrish, 1982). Lead is a potentially toxic chemical that may be directly ingested by man or indirectly through aquatic animals like fish and shellfish .The effects of lead on man include mental retardation, learning dysfuntion, and loss of coord...
ABSTRACT Implementing sustainable development and meeting the food needs of world's increasing population demand national and international investment in research and extension. Before fruitful investment can be guaranteed, inventoly of the present status of the object of investment is imperative. This study examined the present status of public extension network in southwestern Nigeria with a view to ascertain its readiness as a learning organization for forest conservation information. Purp...
Abstract Uncontrolled harvesting of non-timber forest products (NTFPs) poses a serious risk of extermination to several of these species in Nigeria. Yet, there is a paucity of information on the distribution, population status and sustainable management of NTFPs in most of the tropical lowland rainforests. We, therefore, assessed the population, distribution and threats to sustainable management of NTFPs within the tropical lowland rainforests of Omo and Shasha Forest Reserves, south western...
ABSTRACT Triplochiton scleroxylon, Tectona grandis, Gmelina arborea, Nauclea diderichii and Teminalia ivorensis wood blocks were biodegraded in situ in the laboratory by Lenzites palisoti a white rot fungus. The test blocks were cut into 10xlOx20 mm and exposed into the infection region of pure culture of Lenzitespalisoti for 16 weeks. The test blocks were examined for weight loss at 4 weeks interval. The percentages of weight loss obtained after 4, 8, 12 and 16 weeks of incubation of the t...
ABSTRACT This study examined the characteristics and management of street trees in Damaturu, the growing capital city of Yobe State, located in the Sudan savanah ecological zone of Nigeria. Enumeration of street trees was carried out in the major roads of Damaturu to identify tree species and determine population of the species. Data on the management of amenity trees in the town were collected through administration of questionnaire to forestry officials in the State’s Ministry of Environ...
ABSTRACT Inadequate alternative sources of energy and low income engender unsustainable exploitation of the environment by the inhabitants of semi arid regions. Literature abounds on the potentials of Jatropha curcas as an alternative source of energy. This study reports the awareness and acceptability of the energy and other potentials of J. curcas in Kano state. Primary data were collected using FGDs and a set of structured questionnaire administered randomly on 1280 farmers. Information we...
ABSTRACT This study investigated the potential participation of Ibadan residents in the development of urban forestry initiative for environmental rehabilitation of the metropolis. Data were obtained from multi stage randomly sampled 397 residents within the five local government areas (LGAs) in Ibadan metropolis. The result revealed that 49% of the respondents claimed to have trees planted around their residences. Out of this, 83% believed that these trees provide shade for them for recreati...
