| dc.description | In the middle and south part of Libya, groundwater is the main source for all uses due to the extremely low rainfall distribution. Excessive rapid population growth in the urban areas and the high temperature have adversely affected the groundwater quantity. To study the situation, this study aimed to determine key factors affecting the water demand. Specifically, the study assesses the factors that impact on demand for urban residential water and the spatial distribution of the determining demand for urban residential water. The current research is based on a mixed approach. First, SPSS to analyze the questionnaire data. The fieldwork was carried out from January to July 2015. Second, the economic model (E Views) to analyze the time series data, and third, Waikato Environment for Knowledge Analysis (WEKA) and Geographic Information System (GIS) methods were carried out to analyses the spatial distribution in determining urban residential water demand. The relationship between water demand and the independent variables of the study were assessed through an economic model. (R2) test has indicated that both the residues sum and the sum of their squares are moving within 5%, which means that the model is structurally stable. The co- integration analysis has shown a positive significant effect of temperature on water demand over the short and long term with partial flexibility of long-term temperature (5.44). This means that the rise in temperature by 100% increased the water demand by 5.44%. Also, there is a positive relationship between rainfall and water demand in the long term and its less impact in the short term. That because the weakness of the infrastructure in the Libyan state where there are no basins for collecting rainwater for consumption purposes, also low rainfall rates where a large area of the country has desert climate (average 238.6 mm/year). There is a positive significant relationship between urban population and water demand. The greater urban population is greater the water demand and vice versa, partial flexibility of the urban population in the long term is at 0.23. If the urban population increased by 100%, demand for water will increase by 23%. On the other hand, here is a negative significant effect of income on water demand. Therefore, water demand is inflexible to changes in income. The study demonstrated that there is a negative effect in water price in relation to water demand. Estimated long-term variable of water value is 220.98, indicates that if the water price increases by 100%, the demand for water will go down by 221%. It also shows lack of impact in the long run because most of the population in Libya live in the coastal strip. Meanwhile, WEKA analysis indicated that the computational capability of the linear regression model is high, with the lowest error rate of 0.9982, after comparing with Kappa statistical measure. All results were almost perfect. GIS zonation maps of water demand determinants indicated that most of the high values of determinants are concentrated in the northern part of Libya, where there is an increase in population density and urban development. Also, in the southern part, where the highest temperature values were recorded. This study is important to illustrate the most important factors that led to increase the demand for water theoretically using econometrics model and spatial analysis using GIS.,'Certification of Masters/Doctoral Thesis' is not available,Ph.D. | - |
