The package r.sun within the open source Geographical Resources Analysis Support System (GRASS) can be used to compute insolation including temporal and spatial variation of albedo and solar photovoltaic yield. A complete algorithm is presented covering the steps of data acquisition and preprocessing to post simulation whereby candidate lands for incoming solar farms projects are identified. The optimal resolution to acquire reliable solar energy outputs to be integrated into PV system design...
Despite the clear need to reduce greenhouse gas emissions, lack of access to capital and appropriate financing mechanisms has limited the deployment of renewable energy technologies (RETs). Feed-in Tariff (FIT) programs have been used successfully in many countries to make RETs more economically feasible. Unfortunately, the large capital costs of RETs can result in both the slow uptake of FIT programs and incomplete capture of deployment potential. Subsidies are concentrated in financial inst...
This paper provides a review and analysis of the challenges that nuclear power must overcome in order to be considered sustainable. The results make it clear that not only do innovative technical solutions need to be generated for the fundamental inherent environmental burdens of nuclear energy technology, but the nuclear industry must also address difficult issues of equity both in the present and for future generations. The results show that if the concept of just sustainability is applied ...
Geographical Information Systems (GIS) are used today at several planning applications and taking advantage of information technology, this system enable the handling of both spatial and non-spatial data for constructing thematic maps describing a variety of information relating to economic activities. Current research examined the potential of suitable location as well as to study customers' preferences for shopping malls in the area. In this study, evaluation of data concerning the suitab...
This study investigates the level of social welfare services offered in Al-Ain, by gauging how satisfied educators are with the quality and quantity of services offered and its current distribution. This study employs a descriptive survey approach in collecting data from 120 respondents using stratified random sampling. Data was collected using questionnaires, directed to the respondent. Primary data was collected from the key informant through interview among educators, while secondary dat...
Solid waste disposal sites are found on the outskirts of the urban areas, turning into the child sources of contamination due to the incubation and proliferation of flies, mosquitoes, and rodents; that, in turn, are disease transmitters that affect population’s health, which has its organic defenses in a formative and creative state. What to do with solid waste has long troubled governments, industries, and individuals. Therefore, this study was design to determine the effects of the d...
ABSTRACT The study examines the factors that account for the increase in malaria cases in Dvokolwako area (Swaziland), which in the past was generally malaria free. The two main aspects examined in the study area are climate change patterns and sugar cane cultivation under irrigation. Climatic data of the area was obtained from the Mbabane National Meteorological Service, whilst retrospective inpatient malaria data was obtained from Dvokolwako and Mliba clinics. Data on sugar can...
Women’s unequal participation in farm organizations, restrictions on women’s ownership as well as control of resources and unjust legislation give female-headed households to face many problems that their male counterparts do not The problems that plague Nkwene female headed households farmers have been identified as issues related to the economic system, declining rural communities and environmental degradation. Therefore this study was design to examine the role played by female-headed ...
The findings on urban food security in Manzini reported in this paper are based on data from the 2008–2009 AFSUN Urban Food Security Household Survey. We wish to thank the Canadian International Development Agency (CIDA) for funding the study through the UPCD Tier One Program, the eight geography students at the University of Swaziland who administered the survey, the Deputy Prime Minister of Swaziland and his office, and the Ministers of Housing and Urban Development, Education, and Agricu...

ABSTRACTThis study examined effect of climate variability on cassava yield in Ajasse-Ipo. To achieve this aim, this study examined trend of climatic elements of rainfall, minimum and maximum temperature, and relative humidity over the years; examined trend of cassava yield over the years; determined effect of climate variability on yield of cassava and finally predicted future trend of climate variables and their effect on cassava yield. Time series data on climatic elements: rainfall (mm), r...
ABSTRACT Human-wildlife conflicts pose a great challenge to wildlife conservation and are increasing as human migration settlement from rural to urban areas increases, development expands, global climate changes and other human and environmental factors put people and wildlife in greater direct competition for a shrinking resource base. The purpose of this study was to find out the factors influencing human-wildlife conflict in communities surrounding protected areas; a case of OlPejeta Conse...

In Nigeria, as many developing countries, providing energy for the population has proven to be a great challenge thereby increasing dependence on other sources of energy such as fuel-wood. The consumption of forest product such as wood in Nigeria exceeds its regeneration rate thereby resulting in environmental problems such as deforestation, desert encroachment, soil erosion and habitat loss. The aim of the research is to investigate household’s fuel-wood consumption pattern and its impact...
Heavy metals are known to be carcinogenic when consumed by humans above certain permissible limits over a long period of time. This study assessed the concentrations of some heavy metal contaminants in River Romi, Kaduna and the consequences of these heavy metals on human health. The Atomic Absorption Spectroscopy (AAS) technique was employed to assess the concentration of Cd, Pb, Cu, Zn, Fe, Cr and Ni in surface water samples from River Romi. The results of the finding show that the upper ...
