An Assessment Of The Effects Of Desertification In Yobe State, Nigeria, Jibril Musa Phd
An Assessment Of The Effects Of Desertification In Yobe State, Nigeria, Jibril Musa Phd
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
Desertification is one of the most serious environmental and socio-economic problems of our time. Desertification describes circumstances of land degradation in arid, semi-arid and dry sub-humid regions resulting from the climatic variation and human activities. The fundamental goal of this thesis was to assess the effects of desertification in Yobe State, Nigeria. The present threat of desertification in the sahel has reached an alarming stage where crops cultivation and animal rearing/grazing are no more productive, soil has lost its nutrient/fertility, various infrastructure had given way because of windstorm from the neighbouring Niger Republic and sand dunes had taken over. The …

Variations In Climatic Parameters And Food Crop Yields: Implications On Food Security In Benue State, Nigeria., Emmanuel Adamgbe, Fanan Ujoh
Variations In Climatic Parameters And Food Crop Yields: Implications On Food Security In Benue State, Nigeria., Emmanuel Adamgbe, Fanan Ujoh
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
Agricultural production in Nigeria like in other developing countries is highly vulnerable to variations in climatic parameters which may have inverse or direct effect on the performance of food crops. This paper examines the patterns and trends of the variations in the climatic parameters and the implications of such variations on efficient yield rates of some food crops in Benue State using data on climatic variables (rainfall, temperature, sunshine) and the yield of some crops per hectare for 25 years (1986-2010). Data on the climatic variables were collected from the Nigerian Meteorological Agency, AirForce Base, Makurdi while the data on …
Dynamics Of Land Use/Land Cover Changes And Its Implication On Food Security In Anyigba, North Central, Nigeria, Tokula E. Arome, Sunday P. Ejaro (Phd)
Dynamics Of Land Use/Land Cover Changes And Its Implication On Food Security In Anyigba, North Central, Nigeria, Tokula E. Arome, Sunday P. Ejaro (Phd)
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
This study assessed land use/land cover changes and its effect on Agricultural land in Anyigba. The objectives were to identify and delineate different land use / land cover categories, assess the rate of change that occurred and examine the impact of land use/land cover change on food security using satellite remote sensing data collected at three different years (1987 Land sat TM, 2001 Land Sat TM and 2011 Land Sat ETM). The study utilized GIS software such as Idrisi Andes academic and ArcGIS 9.3. The study area covers approximately 31.8km2, and four major land use/cover classes were utilized (built up, …

Forest ecosystem dynamics emerges from nonlinear interactions between adaptive biotic agents (i.e., individual trees) and their relationship with a spatially and temporally heterogeneous abiotic environment. Understanding and predicting the dynamics resulting from these complex interactions is crucial for the sustainable stewardship of ecosystems, particularly in the context of rapidly changing environmental conditions. Here we present iLand (the individual-based forest landscape and disturbance model), a novel approach to simulating forest dynamics as an emergent property of environmental drivers, ecosystem processes and dynamic interactions across scales. Our specific objectives were (i) to describe the model, in particular its novel approach to simulate …
Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais
Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais
Mary Dehais
Nonpoint source (NPS) pollution is one of the leading causes of water quality problems in the United States. Bioretention has become one of the more frequently used stormwater management practices for addressing NPS pollution in urbanized watersheds in New England. Yet despite increased acceptance, bioretention is not widely practiced. This study explores and evaluates the efficacy of bioretention for protecting urban water quality. This research found that numerous monitoring methods are used by researchers and industry experts to assess the effectiveness of stormwater best management practices (BMPs) and low impact development (LID) practices that include bioretention. The two most common …
Socio-Economic Effects Of Demolishing Squatter Settlements And Illegal Structures In Abuja Metropolis, Federal Capital Territory, Nigeria, Ishaku Iy Mallo Phd, Victor G. Obasanya
Socio-Economic Effects Of Demolishing Squatter Settlements And Illegal Structures In Abuja Metropolis, Federal Capital Territory, Nigeria, Ishaku Iy Mallo Phd, Victor G. Obasanya
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
Abuja the Federal Capital Territory and study area is located between latitudes 8o25’ and 9o25’ North of the Equator and longitudes 6o45’ and 7o45’ East of the Greenwich Meridian. The study was carried out in Abuja Phase 1, and it is aimed at highlighting various socioeconomic effects of demolition of illegal structures and informal or squatter settlements on the people within the study area. Data was collected through reconnaissance survey, personal interviews with respondents, and a well laid out questionnaire. The results indicate that the demolition exercise embarked upon by the authorities in the Federal Capital Territory was a response …

Rainfall Variability And Crop Zones Classification For The Federal Capital Territory, Nigeria, Shaibu M. Hassan Phd
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
This study aims at analyzing agro-climatological parameters and establishing a link between some selected agro-climatological indices and sustainability of agricultural production in the Federal Capital Territory (FCT). Two sets of data, climatic and crop yield data were collected and subjected to various agro-climatological analyses. Agro-climatological analyses include the derivation of Onset, Cessation and Length of Rainy Season (LRS), Seasonality Index, Drought Index and Precipitation Periodicity Index. The statistical analyses include monthly and annual means, deviation from the mean, trend line. The result of moisture index in line with crops optimum moisture requirement was used to classify the Territory into agro-climatic …

Suitability Of Low Cost Commercial Off-The-Shelf Aerial Platforms And Consumer Grade Digital Cameras For Small Format Aerial Photography, Anthony Allen Turley
Suitability Of Low Cost Commercial Off-The-Shelf Aerial Platforms And Consumer Grade Digital Cameras For Small Format Aerial Photography, Anthony Allen Turley
Theses, Dissertations and Capstones
Many research projects require the use of aerial images. Wetlands evaluation, crop monitoring, wildfire management, environmental change detection, and forest inventory are but a few of the applications of aerial imagery. Low altitude Small Format Aerial Photography (SFAP) is a bridge between satellite and man-carrying aircraft image acquisition and ground-based photography. The author’s project evaluates digital images acquired using low cost commercial digital cameras and standard model airplanes to determine their suitability for remote sensing applications. Images from two different sites were obtained. Several photo missions were flown over each site, acquiring images in the visible and near infrared electromagnetic …

Desertification of the East Asian drylands and the consequent dust transport have been serious concerns for adjacent Asian countries as well as the western United States. Tree planting has been considered one applicable strategy to mitigate the desertification. However, the desired effect of the tree planting would not be brought to fruition unless the newly planted trees change the coupling characteristics between the land and the atmosphere. Based on this perception, we attempt to clarify the effects of vegetation on the coupling strength between the atmosphere and land surface, and we suggest the most efficient areas of tree planting for …
