Abstract/Overview Forests play a critical role in providing essential goods and services to forest adjacent communities. There is, however, insufficient information on how land uses affect the availability and use of forest products and services by forest adjacent communities. This study analysed the impacts of land use changes on the livelihoods of Mt Elgon forests adjacent communities. Land use changes were assessed for the period 1977-2019 segmented into four time periods corresponding...
Abstract: Reconstruction of climate dynamics in southern Africa has been immensely constrained by the absence of continuous proxies records. Sediments provide potential sources of studying past environments because their makeup is a direct response to variabilities in the environment and climate. In this study a multiple geochemical proxy approach was used to investigate two 30 m deep sediments cores from northern Botswana to construe their various geological processes and environments ...
Abstract: Understanding eastern African paleoclimate is critical for contextualizing early human evolution, adaptation, and dispersal, yet Pleistocene climate of this region and its governing mechanisms remain poorly understood due to the lack of long, orbitally-resolved, terrestrial paleoclimate records. Here we present leaf wax hydrogen isotope records of rainfall from paleolake sediment cores from key time windows that resolve long-term trends, variations, and high-latitude effects on tro...
BACKGROUND OF STUDY According to Chang, K. T. (2008), Geographic Information Retrieval System (GIRS) is a system designed to capture, store, manipulate, analyze, manage and present all types of geographical data. The acronym GIRS is sometimes used for geographical information science or geospatial information a study which refers to the academic discipline or career of working with geographic information system. In simplest terms GIRS is the merging of cartography, statistical analysis and da...
Abstract This paper examined the impact of petroleum exploitation on the environment of the Niger Delta oil producing communities in Nigeria. This is in furtherance of the understanding that human beings are at the centre of concerns for sustainable development. The paper observed that there was need for the adoption of measures that would provide a reasonable degree of protection of ecological and human environment from the activities of the oil industry in Nigeria.
Abstract During the last decades, cities in sub-saharan Africa have undergone rapid urban growth due to increased population growth and high economic activities. This research explores the impacts of varying modelling settings including spatial extend and its location for the city of Nairobi using a cellular automata (CA) urban growth model (UGM). Our UGM used multi-temporal satellite-based data for classification of urban land-use of 1986, 2000 and 2010, road data, slope data and exclusion ...
ABSTRACT The environmental impact of the Liquefied Natural Gas (LNG) Company for the environment and social conditions using the Nigeria Liquefied Natural Gas (NLNG) in Rivers State, Niger Delta area of Nigeria as a case study is analysed in this paper. Specifically, the paper analyses the environment and social consequences of the operations of NLNG on the immediate environment. Data were collected from both the secondary and primary sources. The paper reveals that air borne diseases are the...
ABSTRACT Investigators working in rural communities and small towns in Africa face many obstacles to obtaining a random and representative sample of households for their research. The civic infrastructure used as the building blocks of survey sampling in developed countries are mostly absent in rural Africa. The purpose of the study described in this paper was to pilot an innovative and cost-effective approach to household sampling designed to generate probability samples representative of th...

Factors influencing students choice of Geography
It's an analysis for the decline of geography in our Nigerian secondary schools over the years. The paper looks at the problems and causes of the decline in the subject. By using secondary data from the national examinations body the paper was able to deduce the reasons for the decline. Abstract: Geography as a school subject is one of the most important subjects in senior secondary school education and it’s relevant for students in their pursue of tertiary education cannot be over emph...
ABSTRACT Understanding the spatial variation of urban heat Islands (UHI), will be helpful in urban micro climate studies. This study the urban heat islands of Kaduna metropolis, Nigeria. For the present study Landsat ETM+ images of 2001, 2006, 2009 and OLI 2015 was obtained from USGS of the study area. Normalized Difference Vegetation Index (NDVI) image was developed. The digital number of thermal infrared band is converted in to spectral radiance using the equation supplied by the Landsa...
INTRODUCTION The main objective of this essay is to examine the role played by women in commercialization of agriculture in particular in small holder production of agro exports in MeruAbothuguchi west and non traditional exports especially French beans production. Commercialization of agriculture may take different forms both involving production for domestic market and international market. Is this paper I concentrate on the input of women in output geared towards sale at the internat...
Abstract The paper examines the operations of Public Transport in Nigeria using the Kwara State Transport Service as a case study. Public transportation service in Nigeria is provided by both the public and private operators. While the public Corporations are established by governments private service operations are uncoordinated and poorly organized. Due to the inability of transport operators to solve the mobility needs of Nigerians, the Federal Government established the Federal Urban Mass...
