Horizons and future of water desalination in Libya

A premature study has been conducted to overlook the viability and feasibility of the future of desalination in Libya, by estimating the water situation in several locations in the country. A simplified review of the spectrum of well-known desalination techniques and a presentation of these analysis of the water situation would be highlighted to guideline the planners on how, why and when to embark on desalination to resolve the water shortage problem that would be faced at any moment in the future. Finally the methods to resolve shortage problem alongside their economical evaluation would be considered briefly.     

A Risk Assessment Model of Water Shortage Based on Information Diffusion Technology and its Application in Analyzing Carrying Capacity of Water Resources

A risk assessment model for water shortage was constructed from the risk analysis method based on the information diffusion theory. The application of this model was demonstrated in the city of Jinhua in Zhejiang Province, China. The study indicates that the present model is more stable and effective when compared with the traditional model, based on analytical results from a small sample. The risk assessment result was used to analyze the carrying capacity of water resources from an ecological angle. The author advances that the carrying capacity of water resources should be defined as the maximum bearing capacity of water resources for human activity in certain stages of social development under the sound circle of the ecological system. Further study on Jinhua was also performed in the paper, and the result indicates that water shortage in this city is not of the relevant type of water source and can classified in terms of water quality type as well as water conservancy. In order to verify the result of the theoretical investigation in the present paper, the author also simulates the dynamic changing process of carrying capacity of water resources under the condition of enforcement of the future policy in the city. The simulation uses the model of system dynamics (SD), according to the historical data of the city over twenty years and the governmental standard for comprehensively building a comfortable society by 2020. The paper simultaneously indicates that the primary scheme of unilaterally pursuing the fast development of the economy at the expense of environment and the secondary scheme of taking environmental protection as the primary goal via slowing of development of the economy are undesirable for Jinhua. Furthermore, a scheme of simultaneously giving consideration to both economic development and environmental protection should be the preferred scheme. However, if the present amount of water supply is constantly maintained in the near future, the requirement for water supply will not be satisfied under the balanced considerations of economy and environment. The carrying capacity of water resources in this region can be effectively improved only under the situation of not only strengthening the investment in environmental protection but also increasing income and reducing expenditure year after year.

我国缺水风险分布状况及其对策

在对风险理论及水资源风险研究进展回顾与展望的基础上，探讨了水资源短缺风险主导因子的辨识方法，提出了采用缺水率、人均缺水量和缺水边际损失3个指标的缺水风险评价指标体系，采用模糊层次分析评价方法对全国二级水资源分区的缺水风险进行了综合评价。评价结果表明，全国现状情况下有33个二级水资源分区面临着不同程度的水资源短缺风险，必须采取工程和非工程等防范措施和有效调控，方可减轻缺水风险对我国经济社会发展的危害程度。
