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...
ABSTRACT Rural development has been erroneously equated to agricultural development. The former works to diversify income through non-farm activities to complement proceeds of the latter. However, the actual role of non-farm income in poverty alleviation is not yet known among rural households. There is therefore the need to critically explore the roles of non-farm income diversification in rural poverty alleviation. The patterns and contributions of nonfarm income diversification to poverty...
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...
ABSTRACT This 'study attempts to assess the economic performance of the rubber processing industry in Bendel, Ogun and Ondo States of Nigeria. The Nigerian rubber industry wh ich expeiienced a boom in the early 1950's started to face some serious set-backs during and after the civil war which broke out in 13G7. This setbacks were manifested in form of declining productivity and consequent decline in its contribution to foreign exchange earnings. The study which covers the period 7-1 assesses ...
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...
ABSTRACT East Africa region has imbalances in the supply and demand of common bean. This can be offset by improving marketing infrastructure. The objectives of the study were to determine the characteristics of common bean traders, to determine the constraints to the observed trade in common bean varieties and finally to assess the extent to which markets have integrated in key selected markets. Multi-stage sampling technique was used to obtain a sample of 240 respondents (120 traders from th...
ABSTRACT With increasing population in the main consumption regions of Zambia, there is a persistent shortage in the supply of groundnuts especially in Lusaka and the Copperbelt regions. This is despite the major producing areas of Eastern and Northern regions having significant surpluses. This is a clear indication of market failure to stimulate groundnut production and distribution in addition to excessive price volatility, information asymmetry, and lack of organized and consistent markets...
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 The breeding biology of Macaroni Penguins and of Rockhopper Penguins was studied at Marion Island (46°54'8, 37°45'E) in the austral summers of 1974-75 and 1976-77. The clutch comprises two eggs, the first-laid (A-) egg being markedly smaller than the second-laid (B-) egg. Components of B-eggs are heavier than the same components of A-eggs. Incubation begins after the B-egg is laid. Incubation of B-eggs lasts 34 and 36 days in Rockhopper and Macaroni Penguins respectively. Paren...
ABSTRACT Character variation in Chaetobromus, a genus of palatable grasses endemic to the arid western areas of southern Africa, was used to derive a classification reflecting taxonomic and ecological pattern. The present study differs from earlier biosystematic investigations by its much more intensive approach to sampling, with 75 anatomical, morphological and cytological characters and 169 individual samples being used. The use of larger population samples permitted quantification o~ vari...
ABSTRACT In Southern Mali, small-scale farmers face multiple constraints such as low soil fertility that lead to low agricultural productivity and income. Crop-Livestock Integration System (CLIS) among small-scale farmers has been promoted by extension services to tackle these challenges in order to improve farmers’ livelihoods. Some small-scale farmers have embraced the integrated crop livestock production system and adopted innovations that have been promoted by extension services provide...
ABSTRACT Soybean is an important cash crop with a growing demand in Malawi. Its ability to fix nitrogen has been exploited through the use of rhizobia inoculants to supplement indigenous rhizobia and improve soil fertility. Previous research has however shown instances whereby inoculation has had no yield response which suggests a need to fill the knowledge gap on the nitrogen fixation efficiency of indigenous rhizobia. The main objective of this study was to contribute to increased soybean y...
ABSTRACT Over the last decade Kenyan government has been supporting rabbit research and development activities. The efforts were aimed at raising the productivity of the small holders rabbit producers as a cheap and ease source of animal protein in the rural areas of Kenya despite presence of pulses. But inspite of the efforts rabbit production in Buuri Sub county stands at 1.2 Metric tons of meat against a potential of 8.4 Metric tons per year. This productivity gap is wide and indicative of...
