ABSTRACT There are large areas of Nigeria and probably of West Africa that have never been visited or studied by a geologist or geophysicist. Not so in the region surrounding the Benue Trough. This area has repeatedly attracted a lot of attention in the past, and with the advent of plate tectonics the available geological and geophysical data from the region have been interpreted in various ways to suit different tectonic models. No attempt is made here to review the relevant published work o...
Abstract - Igneous intrusives of basic to intermediate (syenilic) compositions in the Lowcr Bcnue Trough had produced contact cffccts which ro.lge from the lowcr albite- cpidotc hornfels to the cordierite hornfels facies on the host sedimentary rocks which vary mainly from pelitic to calcareous pelitic types. Contact effects of low intensity and size were produced by three smaller igneous bodies of basic composition whose thicknesses range from 1 to 3 m. The mineral assemblages of the aureole...
The efficiency of the sewage works depends on the quality and quantity of the influent and the design of the sewage works. Inefficiency of the sewage work has adverse health impact to the aquatic ecosystem. Pollutants can bio-accumulate and bio-magnify in the food chain causing health impact to both human being and wildlife. The main objective ofthis study was to assess the effectiveness of wastewater management system of Njoro industrial sewage works. This study used descriptive resear...
ABSTRACT The environmental degradation of areas surrounding Lake Elementaita arise from the livelihood activities of the residents. Uncontrolled extraction of resources such as trees, grass and soda/salt contrasts with conservation. This is further compounded by the free access to the resources as a result of absentee landlords. This situation leads to lack of control and management of resources thus exacerbating degradation activities around the Lake and its riparian ecosystem. This study fo...
ABSTRACT The study was conducted in West Usambara Mountains, Tanzania to assess stakeholders diverging interests and emerging resource use conflicts in apiculture with respect to natural resource management (NRM) by local communities. The study aimed at generating knowledge base for effective governance of NRM by farmers and draw lessons for guiding NRM efforts in the study area. Participatory Rural Appraisal, GIS, focused group discussion; questionnaire survey and participant observation we...
ABSTRACT Quantifying tree volume, biomass and Carbon (C) stocks potential of tree crops by using allometric models is vital for understanding the contribution of forests on climate change mitigation effort. The existing allometric models for accurate estimations of total tree volume and total tree biomass for Teak (Tectona grandis) has limitation of application such as models being developed from few sample trees for model development and covered narrow range of diameters and excluded trees...
Abstract Among the key uncertainties in the sustainable management of forest for non-timber forest products (NTFPs) is the high diversity of species and paucity of information on indigenous use pattern. In designing appropriate strategies for sustainable management of non-timber forest products, therefore, it is important to identify species with high local importance with the potential for sustainable and profitable extraction in a managed system. In this study, we assessed the use of two q...
ABSTRACT Sustained wetland functioning needs proper land use planning which in its best requires integrated land management. High anthropogenic pressures on the Kibasira Swamp may undermine its potential in biodiversity conservation and ecosystem services provisioning. A study was conducted to investigate the implications of land use/cover on the biodiversity of Kibasira Swamp. Landsat TM and ETM+ images for the period 1990, 1998 and 2011 were used to quantify the changes. Plants and bird sp...
ABSTRACT Rivers State, The ‘Treasure Base Of The Nation’ and a commercial nerve centre of the Nation has over the years been confronted with the problem of rapid growing human and vehicular traffic congestion. This problem is largely caused by the rate of rural-urban migration of people into Rivers State. In fact, recent statistics have shown that over 10,000 people enter Rivers State on a daily basis. This figure results to an estimated five million people that move around Rivers State ...
ABSTRACT Chukwuenyem, (2007) "People have always sought to portray, in as possible, beliefs, lifestyles, social ills, history, and simple pleasant fiction, through many art forms especially drama recently films. For such exposition the cinema suffices as an invaluable tool." Cinema is an important tool in building cultural institutions, and reinforcing cultural pride. The cinema could be used to heal the psychological wounds created by slavery and colonialism and to provide moral upliftment....
ABSTRACT A study was conducted in Ihale Village, Magu District, Tanzania aimed to assess the effectiveness of selected vegetation cover types as Vegetative Buffer Strip Filters and their corresponding vegetation strip widths in filtering sediment delivery that are likely to enter the surface waters of the Lake Victoria from agricultural lands. Sediment laden runoff plots measuring 2 m by 20, 15, 12.5 and 10 m were established to determine the effectiveness of the selected filters and strip f...
ABSTRACT An assessment of diversity, abundance and distribution of herpetofauna in grassland, kopjes, woodland, riverine forest and wetlands habitats of Serengeti National Park (SENAPA), Tanzania was conducted between December 2012 and March 2013. Drift fence with pitfall, wire mesh funnel traps, active search and visual encounter survey, road survey and purposive point count methods were used to obtain data for this study. Besides, focus group discussion and literature review were used to s...
ABSTRACT A study was conducted in the runoff plots at the University of Nigeria Nsukka Teaching and Research Farm, in 2010 and 2011 to monitor the changes in aggregate stability, and some selected physicochemical properties of Nkpologu sandy loam soil under different cover and soil management systems. The management systems were bare fallow (BF), grass fallow (GF), legume (CE), groundnut (GN), sorghum (SM), and cassava (CA) cultivation. Following the characterization of the soil of the study...
ABSTRACT Flood is a water related natural hazard that affects a wide range of human activities. In the recent past many communities in Owerri have suffered losses as a result of flood. This work utilized Remote Sensing and GIS in flood risk mapping. Data on environmental indices were integrated in a GIS to perform risk / vulnerability assessment. The flood risk map produced and the ground truthing carried out confirmed that the area with the highest flood risk is located within CBN quarters,...
ABSTRACT Lantana camara is one of the alien invasive species introduced to East Usambara about 100 years ago. The species is locally increasing in abundance and spatially advancing to new areas threatening the livelihoods of local communities and biodiversity in nearby Amani Nature Reserve. This study assessed local communities‟ perceptions on Lantana camara focusing on its origin, pathways, socio-economic impacts and management responses in East Usambara. Data was collected through househ...
