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...
ABSTRACT The need for conservation of forests resources, which are presently under continuous depletion, is topical to sustainable development in Nigeria. Despite this, the annual rate of forest depletion in Anambra State is alarming. One of the adduced reasons for this had been inadequate access of residents who rely on forest resources for their livelihood to environmental amelioration information. This study therefore reports the media in use or that could be employed to effectively keep A...
The Title of this paper is PLANT DISEASE DETECTION USING IMAGE PROCESSING,this Paper is based on, detection disorder in plant leaf using image processing.
ABSTRACT This study examined the percentage distribution of benefits obtained from Ibadan urban forest reserves across policy relevant socio-economic classes of the populace in order to draw research and policy implications. Descriptive and inferential statistics were employed to analyse data obtained from a multi-stage random survey of 397 residents of Ibadan metropolis. The results show that benefits obtained from the urban forest reserves do not depend significantly on gender (x2=2.57; p>...
ABSTRACT Rice productivity is low in Nigeria, and NERICA was introduced by West Africa Rice Development Agency (WARDA) to solve this problem. This study focused on NERICA productivity and efficiency in Kaduna State. A three-stage sampling technique was used with Kaduna State being purposively selected. Igabi and Soba Local Government Areas (LGAs) were randomly selected. Five villages were randomly selected from each LGA, with a total of 129 NERICA farmers selected and used for the analysis. ...
ABSTRACT The importance of forests, forest management and related information to human sustainable development cannot be overemphasized. This paper reports the analyses of forestry-related news source and their geographical focus in Guardian and Tribune Newspapers in Nigeria between June, 2009 and May, 2014. Purposive sampling technique was used to select the two National dailies because both have column for environment issues, they are available and their continuous existence for the period...
INTRODUCTION Wood-cement bonded particleboard, was originally invented in Germany about eight decades ago. Since then it has been gaining acceptance in many parts of the world as a sheet element or the building construction-industry. The" interest in the board can be associated with a number of factors. It is highly resistant to flre, insect aud fungal attack and has excellent weather ability and good accoustic insulation properties (Deppe,1974; Dinwoodie, 1978;1981). With respect to the afor...
Abstract Feeding trial were conducted in experimental tanks (50 x 34 x 27 cm) to assess the growth responses and nutrient utilization of Walnut Leaf (WL) and Onion Bulb (OB) residues in Clarias gariepinus. Nine experimental diets: control (0%), OB2 (0.5%), OB3 (1.0%), OB4 (1.5%), OB5 (2.0%), WL6 (0.5%), WL7 (1.0%), WL8 (1.5%) and WL9 (2.0%) were formulated and replicated thrice at 40% crude protein. Fish (mean weight 7.39±0.02 g and length 10.37±1.24 cm) were fed twice daily at 3% body wei...
Abstract Among the key uncertainties in the sustainable management of forest for non-timber forest products (NTFPs) is the high diversity of species and paucity of information on indigenous use pattern. In designing appropriate strategies for sustainable management of non-timber forest products, therefore, it is important to identify species with high local importance with the potential for sustainable and profitable extraction in a managed system. In this study, we assessed the use of two q...
Abstract: Transport of wood biomass is one of the key operations in forestry and in the wood industry. An important part is the transport of shredded wood, where the most common forms are chips and sawdust. The aim of the research was to present the variability of the total weight of trucks (gross vehicle weight, GVW), the weight of the empty trucks (tare), and loads of chips and sawdust in different periods of the year. Changes in specific parameters were analyzed: GVW; tare weight; trailer...
