Reorganising Libya's National Water Resources

AbstractLibya's further economic development depends on the careful use of its coastal aquifers and the economic exploitation of the substantial but remote groundwater resources of the south. The former have been seriously impaired by over-use and the Libyan government has decided to assure water supplies for agriculture, industry and for urban use by moving up to 3 km3 per year of fossil groundwater to the Gulf of Surt and later to the Gefara Plain. The article discusses the scope and significance of the plans and comments on the agricultural implications and the likely ultimate use of the water.

Taihang Mountain

In the 21st century, diminishing water resources have become a global concern. The Taihang Mountain area plays an important role in the sustainable development of the Bohai coastal area in Beijing, Tianjin and Hebei because of its special geographical location and features; but due to drought and deficiency of water, the Taihang Mountain area is faced with the dual problems of poverty and ecological vulnerability. It seems particularly important to develop and utilize the water resources in a sustainable manner as water is one of the key factors in promoting local economic development and improving the ecological environment. This paper investigates, from the perspective of water cycle and water transformation, the seepage recharge mechanism in slopes and river valleys, taking into account the hydrological features of the Taihang Mountain area and the hydro-geological features of slopes and river valleys in the area. Based on analysis of the formation process and characteristics of shallow groundwater resources, this paper puts forth the idea of “weak water consolidation” for sustainable development of water resources, and three groundwater development and utilization techniques in respect of seepage through rock-soil interfaces and weathered rock fissures in slopes and seepage in river valleys, offering a powerful support to the economic development and environmental improvement in the Taihang Mountain area.

Politically Active

In order to facilitate commercial transactions and economic investment after the American Revolution, many inhabitants of northern Virginia became convinced that the region needed financial institutions. Indeed, most politically active residents of the region—at least after the 1790s—saw banks as crucial agents of economic development. Thus, the philosophy of “agrarian republicans” such as Thomas Jefferson and John Taylor of Carolina—who saw banks as monopolistic and anti-republican institutions—had limited appeal in the region. Moreover, the banks of northern Virginia were not controlled by planters who sought capital to finance the purchase of slaves and land. Instead, banks supported a wide range of economic endeavors—agriculture, industry, internal improvement projects, and commercial activities. The broadening access to bank capital in northern Virginia reveals that in the South—as in the northern states—there was a “democratization” of banking in the years after Revolution.

The City

The springs of Aravissos gush out at the south foot of mount Paiko. The water resources of these springs are used mainly for covering the necessities of the city of Thessaloniki. For this purpose Thessaloniki Water Supply & Sewerage Company (ΕΥΑΘ) constructed, two decades ago, the pumping-station of Aravissos. This paper presents the results of the research conducted for the study of the recharge - operation mechanism of the springs and the potential of the water supplying aquifer. For the study of the recharge - operation mechanism of the springs we evaluated data coming from the extensive drilling programs conducted in the area and from the substantial bibliographical references. Respectively, for the study of the water supply potential of the aquifer we evaluated the data coming from gradual pumping of the pumping-station's drillings and from the flow measurements of the spring gushing out at the study area. The contribution of this study on the management of the water supplies of the karstic aquifer of Aravissos can become determi natively important.

The Future

To achieve sustainable utilization of urban water resources and sustainable social and economic development and to relieve the supply–demand pressure related to water resources in Jiamusi, a simulation model based on system dynamics theory is established to identify the feedback mechanism and the causal relationship among the factors affecting the sustainable utilization of water resources. The conditions regarding the utilization of water resources in Jiamusi in 2010 are taken as the benchmark for the model, and the supply–demand structure of urban water resources and the geographical characteristics of the region are used as the basis for its establishment. The model is divided into five subsystems described by 64 variables to simulate the supply–demand structure of the water resources in the region, as well as both the individual supply and demand structures, and thus to obtain the supply–demand conditions and the trends of variation in water resources in the short, medium and long terms. The results show that seriously unbalanced supply–demand conditions for water resources will prevail in Jiamusi in the future. By 2030, the supply–demand ratio will be only 0.5987; the level of development and utilization of surface water resources and transit water resources will be relatively low, and the groundwater resources will still be suffering excessive exploitation; the industrial water demand will be greatly increased, and agricultural development will be restricted. With a focus on the problems that may arise in the utilization of water resources at present and in the future, a proposal regarding the realization of the sustainable utilization of water resources and sustainable social and economic development in Jiamusi is presented. The outcomes of this research have important theoretical and practical significance for providing guidance regarding the scientific and reasonable utilization of water resources in Jiamusi.
