Considering the significance of the crop in the country, cotton has not only been exported to various countries, but some portions of the produce are also used up internally. With that also came, large scale cultivation of the cotton produce on vast swaths of land over the years amidst demands and fluctuations in the marketplace. Given the effects of cotton production on the environment from the use of chemicals and widespread water use, there came changes in the lager agricultural structure that coincided with variations in yield levels, land size and production. Yet, as very little has been done to assess the changing trends in cotton land use in Sudan, no one has bothered to examine the extent and nature of cotton land use and the potentials under a mixscale approach. Accordingly, the paper focusses on cotton land use change, with emphasis on the issues, trends, environmental analysis, impacts, and factors using descriptive statistical techniques connected to Geographic Information Systems (GIS). Through the applications of mixscale model, the study not only showed rising changes in cotton production and yield, but most of the land use indices and the others posted variations as well. While the changes are attributed to a host of socioeconomic , ecological, and political elements located within the local farm system, the GIS mappings of the trends point to the gradual dispersion of cotton land use indices spread across different points in space in the study area. There are also widespread impacts in the form of intense water usage, pollution from chemicals, the loss of land and degradation. Along these lines, despite the efforts of the institutions, the paper proffered solutions ranging from education, monitoring to the design of regional and national cotton land use information system.

Market price support and payments based on unconstrained variable input use are found to be the most environmentally harmful among the various support policies assessed. In contrast, decoupled support payments based on noncurrent crop area are the least harmful. The impacts of support policies that directly change the competitiveness of one production activity in relation to another, such as payments based on current crop area or on animal numbers, are more equivocal.

Identifying the geographic dimensions of wind energy trends and the patterns has the potential to address some of the significant issues communities face. This is highly indispensible in order to ensure self-sufficiency in alternative and sustainable energy systems. This paper will focus on the analysis of geographic dimensions of wind energy use in selected areas of the Midwest region of the United States. The emphasis is on the issues and trends, factors shaping the adoption of wind energy and the impacts of usage. While the paper uses a mix scale method of descriptive statistics and Geographic information systems (GIS) to analyze the trends spatially. Preliminary results show growing use of wind power as an alternative source of energy all through 2002-2013 in the Mid-west. This is evident with the sizable capacity, installed and generated energy, rising potentials, and changing growth rates as well as ec...

At a time of intense ecological uncertainties, regional assessment of tsunami hazards in the region is not only vital, but it offers opportunity in these areas to gauge the level of readiness needed in mitigating eventual disasters. While there is a growing anxiety to the next big seismic catastrophe in the Pacific Northwest states, very little has been done to adequately assess the vulnerability to future tsunamis. Accordingly, this research uses a mix-scale method of descriptive statistics technique connected to GIS and spatial images to evaluate the impending risks in the study area. The results point to widespread occurrence of earth quakes and the continual exposure of the region to the threats of potential tsunamis. The gravity of the risks is manifested by the relative prevalence and likelihood of underwater tremor in the area than other regions of the US. Additionally, the p...

It offers an analysis of oil and gas depletion as well as environmental damage costs in Canada and the United States. It also provides an analyses of the factors responsible for the changes from 1961 to 2000 using a national accounting approach anchored in multi-variate analysis and descriptive statistics connected to Geographic Information Systems (GIS) technology. The major highlights of the book include literature reviews, conceptual dimensions, the profile of the study area with emphasis on oil and gas pollution and costs, the methodological section that describes many components including green accounting model for oil and gas as well as a GIS-based environmental impact assessment and the status of green accounting in both Canada and the United States. The results of the study reveal the occurrence of depletion, growing environmental costs, and the role of economic indicators of gross domestic product (GDP) and gross state pr...

Being a region that spans across different ecozones, access to water and scarcity recurrence in some places are common. In the process, the extent of imbalance in the distribution patterns continues to fuel water insecurity and hydrological stress in the Sahel portion. This contrasts deeply with the abundance in the coastal lower South along the Gulf of Guinea. In as much as the current policy did little to ensure continual access in the zone over the years, water allotment across sectors like agriculture, industry and domestic households are on the uptick compared to the others. Even as access to potable water resources dropped in some places, meeting the stipulated global thresholds on water quality under the Millennium Development Agenda remains elusive in some of the nations. With that has come widespread pollution, degradation, depletion of the resource, limited rainfall, and the menace of drought. Hence, the problem is further compounded by several ecological (physical), and socioeconomic elements located within the larger regional hydrology. This includes the changing climatic parameters, ineffective policy, rising demands, and lack of monitoring. Notwithstanding these challenges, very little has been done in the literature to analyze the issues in water resources use across the study area using the mix scale model. For that, this paper will fill that void by focusing on the challenges in a select group of countries in West Africa. Emphasis is on the issues, trends, impacts, and factors. For the purposes of analysis, the paper uses mix scale methods connected to the techniques of GIS and descriptive statistics. In applying the techniques, the results show widespread use of water and changes, the appearance of degradation, pollution, and water stress due to a set of socioeconomic and physical elements. To remedy the situation, the paper proffered some solutions ranging from the education of the public on water use, the enactment of efficient policy, periodic monitoring, and the design of a regional water management information system.
