Abstract The rural people have been recognized as knowledge holders on climate change. This work examines the socio-economic imperatives of such knowledge particularly as it affects livelihood in selected forest fringe communities in Ondo State, Nigeria. Multistage random sampling technique was adopted in which 4 Local Government Areas (LGAS): Odigbo, Akure North, Owo and Idanre were randomly selected in Ondo state. In each of the LGAs, a forest reserve (Oluwa, Ala, Owo and Idanre, respectiv...
ABSTRACT Tenure issues in natural resources management and control limit agricultural enterprise and effective land use. Conflicts arising from land tenure and tree tenure were examined in eight (8) communities across Northern and Southern Nigeria. The research included preliminary surveys, interviews and questionnaires to obtain relevant information on tenure conflict history, agricultural enterprises, resource user groups and rights exercised in land use and management. Root cause analysis ...

Abstract Consumption pattern and demand analysis of Dacryodes edulis commonly called ube by the Igbos in Umuahia, Nigeria was studied. The various uses and reasons for consumption of Dacryodes edulis, socio- economic characteristics of respondents, income elasticity, and chi square to determine the relationship between Consumption of Dacryodes edulis and some variables that affect it, are addressed. Simple random sampling was adopted. A well-structured questionnaire were used for Dacryodes ed...
Abstract Onifade, A.A. and Abu, O.A. 1998. Productive response of rabbits to supplemental copper in a diet based on tropical feedstuffs. J. Appl. Anim. Res., 13: 129-135. Effects of supplemental copper in a diet based on tropical feedstuffs on productive performance, carcass measurements and haematology of rabbits were investigated in a 70d trial. Copper as CuS04.0H2O was supplemented at 0, 125, 250 and 375 mg kg1 into a basal diet. The basal diet served as control treatment. Eight rabbits, e...
Abstract This study was conducted to assess population structure and threat to the sustainable management of woody species in the various ago-ecosystems in Dutsin-Ma Local Government Area (LGA) Katsina State, Nigeria. Purposive and stratified random sampling techniques were used to collect data from 21 randomly demarcated 100m × 100m sample plots. All woody plant species found in the sample plots with stem diameter >2 cm at 20cm above ground, were recorded. Population structure was summariz...
ABSTRACT The media, especially the newspapers play a major role as sources of biotechnology information and will be useful avenues for disseminating related information. It is in view of this that this study examined coverage of biotech- nology and Genetically Modified Organisms (GMOs) in Nigerian daily newspapers as an avenue to raise mass awareness especially amongst literate farmers. This study content analysed 63 GMOs and biotechnology items framed in four Nigerian newspapers (the Guardi...
EXECUTIVE SUMMARY The Forestry sector plays key roles in supporting the livelihood of all Rwandans by providing most of the energy consumed by the bulk population, controlling soil erosion and protecting water catchments and supplying other goods and ecological services. Hence, the present and future extent of forest coverage in Rwanda is central to sustainable development and climate change considerations. Currently, about 87% of the population and 70% of the country’s land area are de...
Executive Summary Presently, Nigeria is among the nations that are technically unable to meet their food supply needs from rain-fed production at a low level of inputs and appear likely to remain so even at intermediate levels of inputs at some point’s time between 2000 and 2025 (FAO 2002). For the rural areas of semi-arid Northern Nigeria, which experiences significant climatic and anthropogenic changes that have exacerbated food insecurity in the region, floodplain agriculture is criti...
ABSTRACT The study investigated stem distributions and height-diameter relationships of two Irvingiaceae species in Oban Forest, Cross River State, Nigeria with a view to suggesting appropriate management strategies for their conservation in the area. Using systematic sampling technique, six 2km-transect was cut in each of the primary and secondary forests in the area. Four 50m×50m plots were laid alternately along each transect. Thus, twenty-four plots were used in each of the two forest ty...
ABSTRACT Hibiscus sabdariffa is a non-timber-forest-plant (NTFP) that has the potential of producing fibers good in paper-making. Germination and growth potentials of H. sabdariffa under farmland, fallowland, plantation and forest ecosystems were studied. Seeds of H. sabdariffa were sown to assess germination percentage, germination rate, germination time and velocity coefficient on established plots of each ecosystem. Seedlings were randomly selected to measure growth and yield parameters of...
SUMMARY Global warming has heightened the need to substitute fossil fuels with biomass-based energy sources. Some West African countries have recorded appreciable progress in this regard though with inadequate documentation. This study documents the extent of production and use of different biofuels and incentives for sustainability in the sub-region. Field visits were conducted in Benin, Ghana, Niger and Nigeria with the aid of structured questionnaire and focus group discussions; and l...
Lethal and sub-lethal effects of copper on Clarias gariepinus were studied using a 96-hour static bioassay. Copper (as copper chloride, CuCl2 . H2O) was used to prepare the stock solution from which five standard concentrations 0.0, 1.8, 3.2, 5.6, and 10.0 mg/L were prepared (coded A – E). 15 juvenile C. gariepinus fish having a mean weight and length 5.8g and 18 cm respectively were used. The 96-hour LC50 estimated using the logarithm method were 0.6, 0.71 and 0.7 mg/l for replicates...
EXECUTIVE SUMMARY • Following the lessons learnt under the National Fadama Development Project -J, the National Fadama Development Project-II (NFDP-Il) has as one of its major objective to foster the inclusion of all social groups and to ensure that they benefit from the project. These groups are to be included in the participatory planning process that will result in the Local Development plans to be funded and in their implcrncnuuion. Experiences show that there is yet low level of awaren...
