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...
ABSTRACT Reduced Emissions from Deforestation and Degradation (REDD) framework demands measuring of carbon stock changes. In most cases, estimates of carbon stocks rely on volume and biomass estimation allometric models. Although species-specific and some generic models for biomass and volume estimation have been developed for some vegetation types such as Miombo woodlands, their use in Acacia-Commiphora woodlands in dry areas is questionable as they comprise short-height trees with small to...
ABSTRACT Tanzania is rich in pine forests which have the potential to produce valuable resin. In recent years Tanzania has embarked on commercial resin tapping at Sao Hill Forest Plantation. However, current information on resin tapping in the country is scanty and unreliable. Knowledge of factors that affect resin productivity is important for it is those factors that can be manipulated to enhance resin yield. The focus of this study was to fill this knowledge gap by exploring some pine tr...
ABSTRACT Seismic facies classification was done on 3D Prestack Time Migrated seismic data (PSTM) acquired in 1990 in the Bemba Field in the Costal Swamp Depobelt of the Niger Delta, with the aid of STRATIMAGIC™ ( a 3D stratigraphic interpretation tool) and VOXELGEO™ ( a Volume visualization tool) softwares. Three (3) horizons E2000, F2000, G1000 were interpreted. To clearly delineate and control the quality of the auto-tracked picks, horizons attributes (amplitude, dip and azimuth maps) ...
ABSTRACT This study was aimed at empirically identifing the determinants of housing demand in Enugu metropolis. To this end, the objectives of the study were to: (i) examine the trend of housing demand in Enugu Metropolis, (ii) identify factors that influence housing demand (determinants) in Enugu metropolis, (iii) determine whether there is variation in housing demand among various income groups (high, medium and low) in Enugu metropolis and (iv) identify residents’ perception of the hous...
ABSTRACT There are several weather forecasting systems within and outside Tanzania issuing medium-range rainfall forecasts. However, few attempts have been made to evaluate the accuracy of these forecasts. Hence the major objective of this study was to evaluate some selected medium-range rainfall forecasts and forecasting systems issuing those forecasts. Based on the above objective, the study could firstly evaluate medium-range rainfall forecasts in selected bimodal and unimodal areas of Ta...
ABSTRACT The study area is bounded by latitudes 5027’N and 5034’N, and longitudes 7025’E and 7035’E. It falls within the Northern Niger delta Basin. The aim of this present study is to evaluate the hydrocarbon potentials of the sediments in the area, determine their age and environment of deposition. To achieve this aim, geochemical analysis (TOC and Rock-Eval) and Palynological studies were carried out on fifteen (15) samples. Results from the analysis indicates that the total...
ABSTRACT A study was carried out in Mavumo area, West Usambara Mountains, Tanzania, to analyse the importance of landform and soil characteristics in predicting the distribution of plague reservoirs and vectors. The main aim was to contribute to information base that would link landscape and ecological factors with the spatial distribution of plague disease in the area so as to provide information to institutions that are dealing with health and land use programmes in Tanzania. Remote sensi...
ABSTRACT This study attempted to assess floristic composition, stocking and disturbance in MCFR. Specifically, the study aimed to assess plant species richness and diversity, stem density, basal area and volume of the trees, intensity and distribution of disturbance and determine land cover changes for the past 41 years in MCFR. A total of 20 clusters with 100 concentric circular plots with radii 2,5,10 and 15m aligned in four transects across the entire forest of 65710ha were used for the s...

The methodology of the study depended on different sources for data collection on the theories of the impact of sanitation system on the environmental in cities, i.e. references, previous stu...
ABSTRACT Research has shown that the popularization of plastic bottles in Bottling Industries has remained on the increase since middle of 1960's, when high-density polyethylene was introduced. They quickly became popular with both manufacturers and customers due to their lightweight nature and relatively low production costs compared with glass bottles. Except for wine or beer, the food industry has almost completely replaced glass with plastic bottles. Despite this innovation, there has con...
