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 …

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This research work looked in the used of Remote Sensing to improve Agricultural production in Kutigi, Niger State. The aim of the study is to use remote sensing to improve rice farming activities in Kutigi, Niger State. It is very important to identify such methods to improve Agricultural production because experts are always interested in new researches and findings to better the standard of living in any environment. In view of this, Remotely-sensed data could be used or employed to elevate most of these agricultural problems in Kutigi through the following objectives: Using Landsat imagery to assess the present landuse …

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)

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, …

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 …

Wick Irrigation, David A. Bainbridge

David A Bainbridge

Wick irrigation offers the potential for very low cost, robust microirrigation in difficult environments. Wick irrigation was first used in India in combination with buried clay pot irrigation. It has proven itself in the most severe desert conditions.

Straw bale building offers many advantages, high insulation value, thermal mass of interior plaster, resistance to fire, and low embodied resource cost. Super-insulation becomes possible at affordable prices with straw bales. Used with great success for both residential and commercial building projects.

Regional Industrial Structure And Agglomeration Economies: An Analysis Of Productivity In Three Manufacturing Industries, Joshua Drucker, Edward Feser

Edward J Feser

We investigate whether a more concentrated regional industrial structure – the dominance of a few large firms in a given industry in a region – limits agglomeration economies and ultimately diminishes the economic performance of firms in that industry, especially small ones. In an application to three industries using establishment-level production functions and a combination of confidential and publicly available data sources, we find a consistently negative and substantial direct productivity effect associated with regional industrial structure concentration and only mixed and relatively weak evidence that agglomeration economies are a mediating factor in that effect.

The Bonds That Tie: Will A Performance Bond Require That A Surety Deliver A Certified Green Building?, Darren Prum, Lorilee Medders

Darren A. Prum

In 2006, the city of Washington, D. C. passed landmark legislation that introduced green building requirements for various types of structures into the jurisdiction over a five-year period. A noteworthy aspect of the legislation directed construction projects within the district to purchase green performance bonds up to $3 million to guard against a privately owned project’s failure to meet its green building aspirations. In essence, this law placed the burden of guaranteeing compliance with the government’s policy upon the contractors and sureties of a green building project.

Following the passage of this act, confusion amongst the construction industry and sureties …
