Access to clean and stable electricity is essential in actualizing Nigeria's quest for joining the league of twenty most industrious nations by the year 2020 (vision 20:2020). No country can develop and sustain it development without having a minimum access to electricity for it larger percentage of its population. At present, Nigeria depends petroleum reserves and its aged hydro plant instalments for electricity generation to feed the 40% of its total population that are connected to the national grid. This paper summarizes literature on the current energy issues in Nigeria and introduces the difficulty of the issues involved. The paper also analyses the current (2010) electricity generation as well as the future expansion plans of the Government in 20 years period. The plan includes the introduction of new electrify generation technologies that have not been in used in the base year (2010). The electricity generation system of (including the future expansion plan) was simulated using the LEAP System (Long-range Energy Alternative and Planning). We also investigated the potential environmental impact of siting a nuclear power plant in one of the potential sites based on the site's specific micro-meteorology (land use) and meteorology using the US EPA (Environmental Protection Agency) models; AERMOD 12345. © 2013 Elsevier Ltd.

Sexual dimorphism was examined in 221 randomly selected adult African Muscovy ducks extensively reared in north central Nigeria using univariate and multivariate measures of body size and skeletal proportions. The body parameters investigated included body weight, 8 primary linear body measurements [breast circumference (BTC), thigh circumference (THC), body length (BDL), bill length (BLL), neck length (NKL),foot length (FTL), total leg length (TLL) and wing length (WNL)] and 4 morphological indices (massiveness, stockiness, long-leggedness and condition index). The univariate analysis showed male dominance (p<0.05) in all the morphometric measurements, with the exception of stockiness and longleggedness where significantly higher mean values were recorded for females. Low, moderate and high positive and negative correlations among the body size and shape characters of the ducks were recorded. The canonical discriminant analysis on body weight and primary linear body measurements revealed that wing length was the most discriminating variable between the sexes, followed by body weight, neck circumference, total leg length, body length and foot length respectively. Three other variables not qualified to enter the model were expunged. The single discriminant function obtained (D= -3.116 + 0.280WNL+ 0.921BWT + 0.191NKL - 0.196TLL - 0.063BDL - 0.283FTL) correctly classified 91.4% of individuals of known-sex ducks. This might aid in ecological studies, conservation and improvement of the indigenous ducks. Source

Natural aquatic plants population can be healthy for any aquatic ecosystems as they serve as fish feed, play an important role in nutrient cycling, purify the water, control unwanted algal growth and support fauna including birds. Water hyacinths (Eichhornia crassipes) have proven to be a persistent and expensive aquatic weed problem. The review was carried out in the face of current global challenge (climate change) which threatens biodiversity conservation and sustainable use of natural resources so that water hyacinth could be viewed as an asset of multifarious benefits considering the revealed highlights rather than been labeled expensive nuisance. The simplest method of management of aquatic weeds is to harvest it and utilize it for cost effectiveness in production such preparation of fish and livestock feeds, bio-gas production, making of charcoal briquetting and waste water treatment for domestic and industrial use. The main problem of utilization and management of water hyacinth is its high cost of transportation to sites for utilization but once this can be overcome as revealed in the review appropriate utilization techniques is recommended. © 2013 Academic Journals Inc.

A study was carried out using 520 household across three states of Benue, Nasarawa and Plateau to characterize goat production and breeding objective traits in north- central Nigeria. Data was collected through participatory rural appraisal (PRA) method, structured questionnaire and interviews were used to determine the productivity of local goats, breeding traits preference and factors used to decide which goat to keep in communal production system. Results obtained indicated that West African Dwarf goat was the main goat breed reared in this zone. Mating was natural and uncontrolled. Herd sizes recorded were 8.48±1.20, 11.71±0.61 and 7.12±1.11 while litter size was 1.6±0.01, 1.4±0.03 and 1.2±0.02 for Benue, Nasarawa and Plateau States respectively. Fast growth, disease resistance, temperament and mothering ability were ranked as the very important attributes in all the communities. Coat colour and body conformation were reported to be of little value as preference traits. The goats have the potential to produce good litter size and attain lower weaning mortality. The communal smallholder goat keeper in this zone selects their breeding stocks based on some adaptive traits such as disease resistance, and also on inherent traits such as temperament, mothering ability and fast growth rate. Inbreeding rate estimated using standard procedure, among the population was low and indication that the goat population at this region is not at risk. It can be concluded that the breeding strategy for the goat is similar in this region. The findings in this study can be used to design an appropriate programme for improvement and conservation of this indigenous goat. © 2016, Fundacion CIPAV. All Rights Reserved. Source

The changes that have taken place in Nigerian fisheries are reviewed, with the major contributor to fish production in the Nigerian fishery sector which is the Artisanal fishery. From data accumulated over the years by Nigerian Institute for Oceanography and Marine Research (NIOMR) on fishery resources in our coastal waters, fish and shrimps are being over exploited that they no longer sustain the number of registered vessels. Consequently, the potential or maximum sustainable yields must be thoroughly examined on regular basis via sufficient data to determine the status of the fisheries resources and embark on necessary actions that ensure its sustain ab ility. The important ability of fisheries statistics for sustainable fisheries management and under-explored potential of Nigerian waters is also highlighted. The need for human resources development (fisheries statisticians) at each national level was also enumerated and it was identified to operate at regional levels through government funding for joint effective participation. The need to adopt and develop strategie s/technologies that ease addressing the present and uncertainties about future positions of our fisheries was emphasized. The advantages resulting for fisheries sciences are examined and illustrated with examples and the understanding of some alleged weaknesses in some popular concepts and theories would enhance technology adoption with adaptation in making explicit inferences and decisions for the sustainable management of both the present and future situation of our fisheries resources. © 2011 Academic Journals Inc.
