ABSTRACT The study employed the sustainable livelihood approach to investigate the effect of mining activities on male and female smallholder farmers in the Mpohor District mining area. In addition, livelihood assets of smallholder farmers, heavy metal concentrations in farm soils, the livelihood strategies employed by the smallholder farmers and institutional support to the smallholder farmer in the management of the effect of mining activities were also assessed. Five communities namely; Mp...
ABSTRACT The study investigates the spatial distribution and concentration of air pollutants (mainly from automobile emission) at traffic intersections at selected major routes within Port-Harcourt Metropolis, Rivers State, Nigeria. Five sampling locations (using purposive sampling technique in selecting the sampling locations) were considered which are Rumuokoro, Rumuola, Garrison, UST/Mile 3 and Mile 1, with each having three sampling points placed 2.0m away from the edge of the road and s...
Vegetables are grown for human consumption all over the world. Indigenous Leafy Vegetables (ILV), both wild and domesticated species make important contributions to household improvement in Nigeria. However, information on availability of these species in the market and the consumption level at household is limited. Therefore, ILV species in southeastern Nigeria were investigated in order to determine their availability and consumption level. Multi-stage random sampling procedure was ado...
Khaya grandifoliola, an important economic hardwood species, has been severely depleted by overexploitation. This necessitates its ex-situ conservation and requires in-depth knowledge of nursery handlings, seed storage, in-vitro and ex-vitro propagation on which information is sparse. Therefore, silvicultural requirements for conservation and sustainable use of K. grandifoliola in some parts of southern Nigeria were investigated in this study. Seeds of K. grandifoliola were purposively s...
Non-Timber Forest Products (NTFPs) have been identified to contribute to community livelihoods. Such contributions are people as well as site specific and may be short lived if continuous availability cannot be guaranteed. Information on the role of NTFPs in community livelihoods is crucial to their sustainable management; however, this role has not been properly documented in Taraba State. Therefore, contributions of selected NTFPs to community livelihoods in Taraba State were investiga...

The preservative treatment of non-durable lignocellulosic materials, such as Bambusa vulgaris (bamboo) enhances its service life. Thermally modified lignocellulosic biomaterial is better than chemically treated products because it is environmentally friendly. However, there is a dearth of information on the characterisation properties of thermally modified Bambusa vulgaris. This study was therefore conducted to characterise the properties of thermally modified Bambusa vulgaris. One thou...
Development of empirical models provides ample prospects of exploring established mathematical theories and relationships among tree growth variables for sustainable forest management options. However, there is inadequate information on modelling growth characteristics and productivity potentials of Pinus caribaea, a pulpwood species which is now being proposed for timber production in Nigeria. Hence, models for growth characteristics and their applications in yield studies for Pinus car...
ABSTRACT Hydrogeochemical study of the origin of underground mine water at Golden Star Bogoso/ Prestea Limited (New Century Mines) was carried out to determine the geochemical processes controlling surface water, groundwater and underground mine water and to identify the source of recharge to the underground water in the mines; investigate the hydrochemical facies of groundwater in the various aquifers (gallaries), and identify the relationship between surface water and groundwater, and under...
ABSTRACT Academic institutions produce solid wastes which are not disposed off effectively or economically. The result is littering and accumulation of garbage which cause pollution. This study examined solid waste generation and management practices in public and private institutions. To achieve the above objective, waste audit was carried out over a period of three weeks. Waste management practices of the institutions were also examined through the assessment of the institutional arrangemen...
ABSTRACT Autolysed brewery yeast waste is currently being used as cost effective protein bait for Bactrocera invadens control the world over to replace commercial protein hydrolysate bait formulations. However, significant reduction in production cost can be achieved when all the production materials are from local sources. This experiment was aimed at assessing the efficacy of locally produced papain extracted from ―Red lady‖ pawpaw fruit latex and skin peel to be used for protein bait p...
ABSTRACT User satisfaction with residential houses generally is tied to many variables, but this research aims at examining user satisfaction with architectural designed spaces of residential buildings using insights from Plateau State Low-cost housing. The designed spaces of low-cost houses constitute verandah, living room, dining, kitchen, store, bedroom, toilet/ bathroom courtyard and external spaces for parking and outdoor activities. Physical observation of low-cost houses in Plateau St...
ABSTRACT The study was conducted in the Dangbe West District of the Greater Accra Region. The main objective of the study was to find out how rice farmers access and manage credit to improve their families standard of living. The specific objectives were to find out about available credit packages for rice farmers at the Kpong Irrigation Project, examine why rice farmers at Kpong Irrigation Project access credit, determine the benefits rice farmers may derive from using credit, evaluate the p...

ABSTRACT Laboratory experiments were carried out to evaluate the effect of steaming cowpeas on the oviposition and larval development of the cowpea beetle, Callosobruchus maculatus (F.). The possibility of oven and solar drying as well as the effect of the initial temperature of the cowpeas on the steaming effect were also investigated. Samples of four cowpea varieties (Soronko, Asontem, Amantin and US Blackeye) were steamed for 10 and 15 minutes and solar or oven dried. Some initially stored...
