ABSTRACT The study was carried out to evaluate the effect of anthropogenic activities on physiochemical properties of soils in Ezinihitte Mbaise L.G.A. Imo State. 36 soil samples were collected randomly at the depth of 0-5cm, 5-15cm, and 15-30cm. The samples were collected from four different locations, farmland, market area, play ground and forest. The samples were prepared and analyzed for physiochemical properties such as sand, silt, clay, pH, conductivity, organic carbon, moisture content...
ABSTRACT The study evaluated the effect of anthropogenic activities on the physico-chemical properties of soils of Awka South, LGA, Anambra state, Southeastern Nigeria. Triplicate soil samples were collected from three (3) soil depths (0-15cm, 15-30 cm and 30-45 cm) in four land use types; sand mining, play ground, arable land and forest land of Agu Awka, Amowbia, Okpuno and Ifite respectively. Physico-chemical properties and heavy metals concentration of the soils were analyzed using standar...
ABSTRACT This study investigated the concentrations of Polycyclic aromatic hydrocarbons (PAHs) and five selected heavy metals (Pb, Cd, Ni, Zn and Cu) in water and soil at some selected auto-mechanic shops within the Accra Metropolis. In all 57 soil samples and 36 water samples were collected between December 2015 and February 2016 from eighteen (18) selected auto-mechanic workshops, three (3) hand-dug wells and two (2) control sites. The samples were extracted and analyzed for PAHs (naphthal...
ABSTRACT Cage aquaculture involves fish farming in floating cages in an existing water body that permits exchange of water, nutrients and waste materials between the cage and the water environment. While some experts claim that cage aquaculture negatively impacts on water quality, others found no significant impacts of fish farming in floating cages on water environment. While information on cage aquaculture abounds in some countries to enhance the industry, little information exist on the i...
ABSTRACT A highly diverse set of user groups depend on freshwater resources and services for domestic use, agricultural and industrial purposes as well as ecosystem functioning. Many freshwater supply sources are already over allocated, suffer degraded water quality, and are often not in sufficient condition to support life. The steps towards poverty reduction that targets sustainable development will be jeopardized if improved water resources management and effective storage measures are no...
CHAPTER ONE INTRODUCTION 1.0 Background With the increasing population and increasing per capita water demands, certain areas will soon face the problem of needing more water than can be obtained from local water supplies. This projected water deficit has instigated an interest in water reclamation and reuse, using treated waste waters as a public water supply source. Ghana is no exception to the countries around the world, experiencing high volumes of wastewater that flows out without rec...

ABSTRACT Crude oil spillage is a big threat to the soil fertility. Spillage occurs due to the pipeline rupture, and traffic accidents involving tankers. An investigation was carried to assess the effects of crude oil spillage on the physicochemical properties of soil in Nnagi-Ama, Niger Delta Nigeria. For this purpose soil samples were collected in the Nnagi-Ama, tested in a laboratory, and compared to non-polluted (control) soil sample. The pH values of the soil samples remained almost t...
ABSTRACT The research was conducted to study the effects of pollution its prevention, and challenges in urban environment in case study of Kampala central division The following forms of pollution were studied (Air, Water, and Land). Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Within the Kampala Central Division there are a good number human activiti...
ABSTRACT Unlike many areas of the world where agricultural producers exhibit the physical, economic and social resources to moderate, or adapt, subsistence agriculture in the Juba County South Sudan is seem to be particularly vulnerable to the impacts of climatic variability. This is in part due to the fact that the majority of the population depends on rain-fed agriculture for their livelihood. J-dapting to climate change in the subsistence agricultural sector is therefore very imperative i...
ABSTRACT Artisanal and Small Scale Gold Mining is considered to be the most appropriate means of improving local communities’ livelihood. Particular emphasis was directed to the existing Mugusu small scale mining situated in Mugusu village in Geita district. The study focused on the operational practices of the existing gold mining, the pertaining problems and how various parties have resorted in addressing the emerged conflicts. The study was guided by four specific objectives namely, to ...
ABSTRACT This study was carried to investigate the effects of poor water supply to the community of Kamuda Sub-County, Soroti District, Eastern Uganda. Data was collected through the use of questionnaires accompanied by observation and questionnaires. The study involved a sample of 50 respondents; these were all involved in different activities at different levels. The study further revealed 40% access water through wells implying that it was the common source of water around, 15% of the re...
ABSTRACT The study was conducted to establish the effects of quarrying on the environment using Tala, Machakos district as the case study in Kenya. Machakos district is found in the Eastern province of Kenya. It was intended to establish the extent to which quarrying has affected the environment in Tala. To examine what are the causes of quarrying and suggest the possible measures through which quarrying effects on the environment. Fifty (50) respondents were randomly selected and these incl...
ABSTRACT A study on assessing the impacts of agriculture on protected areas was carried out in Arusha National Park in Tanzania. The variables considered include identifying the factors influencing agriculture around Arusha National Park (ANAPA) and major type of agriculture activities carried out, examining the impacts of these activities on ANAPA and identify the effort of local community and NGOs and National Park Authority to address these effects of agricultural activities on ANAPA and ...
