Hydrogeological And Hydrochemical Characterization of Crystalline Basement Rocks in The Upper District Region; The Talensi District

ABSTRACT Groundwater remains the single most important source of water in Talensi district for various purposes. Notwithstanding, little research on the quality and sustainability of the resource in the district exist. Hence a comprehensive quality assessment and a quantification of groundwater resources in the shallow unconfined aquifers of the Talensi district has been conducted using conventional graphical methods, mass balance and multivariate statistical techniques coupled with steady s...

Studies On Bovine Coccidia [Apicomplexia: Eimeriidae] In Parts Of Plateau State, Nigeria

ABSTRACT A parasitological examination of 2,500 faecal samples of cattle was carried out in Plateau State, Nigeria, to determine prevalence, seasonal distribution and sources of various species of Eimeria in both sexes, age groups, breeds and husbandry systems. Effects of temperatures on sporulation of Eimeria oocysts and chemical analysis of the Eimeria oocysts were also determined. Out of 2500 samples examined, 1567 i.e 62.68% were positive for twelve species of Eimeria. E. alabamensis occu...

Rattle Tree (Albizia Lebbeck) Effects On Soil Properties And Productivity Of Irish Potato (Solanum Tuberosum) On The Jos Plateau, Nigeria

ABSTRACT This study was carried out with the aim of assessing the rattle tree (Albizia lebbeck) effects on soil properties and Irish potato (Solanum tuberosum) productivity on the Jos Plateau, Nigeria. In carrying out the research, a randomized complete block design (RCBD) was employed consisting of five treatments and three replicates. The five treatments applied were as follows: Treatment 1 (T1): Irish potato planted in the alley (space) between A. lebbeck tree rows without green manure; T2...

ABSTRACT The need for accurate positions of facilities beneath earth’s surface can never be overemphasized. Detail survey which seeks to record the finished or the existing planimetric features in a piece of land has been utilized over the years for several purposes. The purpose of this study is to map sub – surface water pipelines at New Haven, Enugu North Local Government Area, Enugu State using modern survey techniques. This survey was required for the purposes of knowing the précise...

The Effect Of Mining Activities On Smallholder Agriculture: The Case Of Male And Female Farmers In The Mpohor Mining Area Of Ghana

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...

Geospatial Distribution of Air Pollutants Along Selected Traffic Routes Within Port Harcourt Metropolis

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...

VALUATION OF THE CONSUMPTIVE AND PRODUCTIVE USES OF WILD AND DOMESTICATED INDIGENOUS LEAFY VEGETABLES IN SOUTHEASTERN NIGERIA

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...

SILVICULTURAL AND CONSERVATION TECHNIQUES FOR Khaya grandifoliola C. DC. IN SOUTHERN NIGERIA

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...

CONTRIBUTIONS OF SELECTED NON-TIMBER FOREST PRODUCTS TO COMMUNITY LIVELIHOODS IN TARABA STATE, NIGERIA

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...

CHARACTERISATION OF SELECTED WOOD PROPERTIES OF THERMALMODIFIED Bambusa vulgaris SCHRAD.EX J.C.WENDL

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...

MODELS FOR GROWTH CHARACTERISTICS AND THEIR APPLICATIONS IN YIELD STUDIES FOR Pinus caribaea Morelet 1851 IN SOUTHWESTERN NIGERIA

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...
