ABSTRACT This study determined the impacts of chemical application on plant biodiversity in comparison to the control ecosystems over a three-year period at Neudamm farm in Khomas Region, Namibia. In this study, for herbaceous plant sampling, a total of 40 (1m2 ) quadrats were randomly laid in each of the three chemically treated sites (treated in 2015, 2016 and 2017) and in the control site to record the herbaceous plant density, plant species composition, dry matter production and ground c...
ABSTRACT Development interventions are aimed at promoting positive change, but they can equally have negative impact, especially in conflict-prone contexts. Whereas existing studies on Odi and the Niger Delta at large mainly focused on the history, environ-ment, culture, conflict and security situations, the peace and conflict impact of Nige-rian government‘s socio-economic interventions in the area have not been fully ex-plored. This study, therefore, assessed the Niger Delta Development C...
Abstract: The aim of this study was to investigate the morphology of Macrotermes bellicosus present on some parts of the University of Ibadan and to determine the effect of the saliva of termites on the strength of termitarium. Termites were collected from 8 termitaria on Parry Road, University of Ibadan and characteristics morphometrics were measured using stage graticules (10mm) on Microscope. Amylase analysis was conducted to determine the activity of the saliva content in the termitarium ...
ABSTRACT Low and arbitrary review of forest charges encourage waste and poor harvesting practices resulting in underdevelopment of forest resources. The study therefore assessed the type, value and changes in the value of forest charges in Kogi State between 1991 and 2009. Data on forest charges between 1991 when the state was created and 2009 were collected from the Forestry Service of Kogi State. GDP deflator was used to convert the forest charges in each year under study to real or constan...
ABSTRACT In Nigeria, high cost of Domestic Energy (DE) has put untold hardship on households. Coping strategy is therefore imperative to meet household domestic cooking and heating needs. Investigating evolving strategies would better inform DE experts and policy makers. This study was therefore designed to investigate strategies devised by households in Northeastern Nigeria for coping with the escalating prices of DE. The domestic energy types considered in the study include Liquefied Natura...
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...
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 (...
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...
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...
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 ...
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...
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...
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...
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...
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...
