Agroforestry Practices And Their Potential Contributions To Soil Fertility And Food Production In Katsina State

ABSTRACT Unsustainable forest land use practices have resulted in land degradation in the northern part of Nigeria leading to low crop yield. Agroforestry is a viable option for reversing dwindling crop yields through proper soil management practices. There is notably no sufficient published information on the contributions of agroforestry to food production in Katsina State. The practices of agroforestry and its potential to slow down the pace of soil degradation and boost food production in...

Assessment Of Soil Pollution (Heavy Metal) From Small Scale Gold Mining Activities: A Case Of Nyarugusu Gold Mines, Geita – Tanzania

Abstract This research study investigated the concentrations of some heavy metals (Hg, Pb, Cu and Zn) in soil samples collected from Nyarugusu Gold Mines (located in Geita Region, Tanzania) using Atomic Absorption Spectroscopy (AAS). The results obtained showed that average concentration for Hg (25.45 mg/kg) was higher than the tolerable limits recommended by the United States Environmental Protection Agency (US-EPA). The average concentrations for Pb (10.14 mg/kg), Cu (19.75 mg/kg) and Zn (...

Implications Of Rapid Urban Expansion On Rural Land Use In Damaturu, Yobe State, Nigeria

ABSTRACT The implications of rapidly expanding cities on rural hinterlands have been documented in the literature. However, such implications are understudied in developing nations including Nigeria. This study, therefore, investigated the implications of rapid expansion of Damaturu, Yobe State, the fastest expanding state capital in northern Nigeria on rural land use pattern from 1986 to 2009. Environmental resource carrying capacity and distance decay effect provided the analytical framewor...

Hydrochemical Assessment Of Surface Water In Part Of Southeastern Nigeria

ABSTRACT The area of study occurs mainly within the Calabar Flank and part of the adjacent basement terrain of the Oban Massif. The latter is composed of mainly migmatitic gneisses, phyllites, amphibolites, granites, schists and granodiorites, while the major lithologies of the Calabar Flank include carbonates, shales, claystones and sandstones. This study aims at determining the quality and usability of the water, in addition to ascertaining the possible pollutants and ways to ameliorate the...

The Nature And Challenges Of Street Sweeping In Ado-Ekiti

ABSTRACT This study examined the nature of street sweeping, the composition of litters, the socio-economic and health status of street sweepers and the public perception of the benefits and challenges of street sweeping in Ado-Ekiti. Primary data were obtained through direct personal observation, questionnaire administration and in-depth interview while secondary data were sourced from published and unpublished documents. Purposive and random sampling methods were adopted in the selection of ...

Socio-economic factors influencing marketing of non-timber forest products in tropical lowland rainforests of south-western Nigeria

ABSTRACT A number of factors persist to constrain the non-timber forest products (NTFPs) market and, by extension, its potential to contribute meaningfully to livelihood development and poverty reduction objectives. To better utilise the potential of NTFPs, it is important to have a better understanding of the key factors governing the success and failure of NTFPs trade. This paper reports on the market constraints and socio-economic factors that influence trade in five top-priority NTFPs wit...

Exploring the Trip Chaining Behaviour of Women using Public Transportation in Ibadan, Nigeria

Abstract Women multi-tasking activities impose a powerful influence on their trip pattern. The study examined the trip sequencing and challenges faced by women using public transport in Ibadan Metropolis. Two hundred and three (203) women were served with structured questionnaire in 10 selected bus stops, using purposive sampling. Only 190 correctly filled questionnaires were subsequently analyzed. Both descriptive and inferential statistics were used for data analysis. Findings indicated tha...

The rate of compliance to seat belt usage among automobile drivers on three categories of roads in Nigeria: an observational survey

ABSTRACT  Injuries to head, chest and abdomen are a major cause of death for unrestrained vehicle occupants, particularly the drivers. The use of seat belts therefore plays a significant role in reducing the severity of injuries. The study examined the compliance rate of seat belt use on different road hierarchies in Abeokuta (Nigeria) using an observatory method. Findings indicated that there was 54%, 37.3% and 13.6% compliance rate on three categories of roads studied. Also, females compli...

Evaluation of The Toxicity And Anthelminthic Effect of Methanol Extract of Duranta erecta Fruits

ABSTRACT The chemotherapy of gastrointestinal helminthiasis relies mainly on the use of anthelmintics. However, concerns over drug resistance have encouraged the search for new drug leads. This project report focused on evaluating the toxicity and anthelminthic effect produced in vitro and in vivo by the methanol extract of Duranta erecta fruits. From the study, the plant extract was found to contain several chemical components including flavonoids, tannins, polyuronides, saponins, glycoside...

Drought stress on early growth of Diospyros mespiliformis Hochst ex A. Rich in Jega, Northern Nigeria

ABSTRACT Trees face rising drought stress and mortality with global warming and it is vital that adequate information is available on the tolerance levels of tree species. In 2012, seedlings of Diospyros mespiliformis Hochst ex A. Rich were evaluated for response to varied levels of water availability at the Aliero Teaching and Research Farm, Kebbi State University of Science and Technology, Jega, Kebbi State, Nigeria. Twelve uniformly growing potted seedlings were selected and exposed to fou...

Assessment of Community Based Forest Management Practices in Benue State, Nigeria

Abstract: Forests in Benue State are depleting due to anthropogenic activities. Community based forest management had been suggested by various researchers as being capable of stemming the rate of destruction of forests. This study was therefore carried out to assess the presence, mode and level of participation in community based forests practices in Benue State with a view to corroborate or dispute the veracity of the practice. Stratified multistage random sampling method was adopted to sel...

Determination of The Concentration of Pollutants From Warri Refinery Effluent And its Impact on Water Quality of Ubeji River

Abstract This study investigated the effects of effluent discharged from Warri Refinery on the water quality of Ubeji River, Warri Delta state. Water samples were collected from upstream, point of discharge of effluent and downstream sections of the river. Physicochemical parameters (turbidity, pH, electrical conductivity, total dissolved solid, total suspended solid, turbidity, dissolved oxygen, biological oxygen demand, chemical oxygen demand, oil and grease), concentrations of polycyclic ...

Innoson Automobile Exhibition, Sales And Maintenance Centre Enugu: A Study on Circulation

ABSTRACT Automobile exhibition and sales centre refers to a place or structure specifically designed for display and sales of cars and its buyers, planned as a unified structure to create an avenue for buyers and those who dream of owning a car to enjoy such coordinated and friendly environment. Its friendly environment gives not only a high standard of commercial activities, but special natural or manmade environment for such experience. A theoretical, as well aspractical key issue in the d...

Silvicultural Requirements For Conservation Of Plukenetia Conophora (Mull Arg) In Southwestern Nigeria

ABSTRACT Plukenetia conophora, a liana with economic potentials is threatened by extinction. Ex-situ conservation of the species which requires knowledge of its early growth and vegetative propagation has the potentials to enhance its sustainability. However information on the silvicultural requirements for the early growth of this species is scanty. Hence, in this study, seed germination, seedling growth, macro and micropropagation of Plukenetia conophora in Southwestern Nigeria were investi...
