Effects of public participation in urban planning: the case of Nablus city
Due to water scarcity, it is important to organize and regulate water resources utilization to satisfy the conflicting water demands and needs. This paper aims to describe a comprehensive methodology for managing the water sector of a defined urbanized region, using the robust capabilities of a Geographic Information System (GIS). The proposed methodology is based on finding alternatives to cover the gap between recent supplies and future demands. Nablus which is a main governorate located in the north of West Bank, Palestine, was selected as case study because this area is classified as arid to semi-arid area. In fact, GIS integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographic information. The resulted plan of Nablus represents an example of the proposed methodology implementation and a valid framework for the elaboration of a water master plan
Agricultural Water Use Impact on the Eastern Aquifer Basin Sustainability Under Climate Change Uncertainty
Aplicação de eficiência sustentável em polÃticas de reafetação da água
Dissertação de mestrado em Urban EngineeringWater is globally scarce and highly competitive among several users. In fact, UN estimates that
more than 40% of the global population is projected to be living in areas of severe water stress
through 2050. The only foreseeable way to deal with this scarcity is by well-managing the
available and accessible resources. The objective of this work is to promote water efficient use
through systemically measuring the performance of a defined water system (WS) using
sustainable efficiency (Sefficiency) as a tool. The general framework of Sefficiency, which is an advanced
efficiency indicator that considers the usefulness criterion (water quality and beneficence
characteristics), was suggested and detailed by Haie, et al. in their 2012 paper. In order to achieve
the final efficiency results after the selection of a WS, data collection and acquisition processes
are needed to characterize the WS under consideration quantitatively, qualitatively and
beneficially. Tomato crop farmlands located in Davis City, Yolo County at the west bank of the
largest river in California State, Sacramento River, were selected as a WS because of the
seriousness of water drought series in addition to the distinguished economic value of agriculture
there. The Sefficiency results of the WS under consideration showed relatively inefficient
performance at the local level inside the system; symptoms of polluting impacts by the WS on
the river; and considerably satisfactory recharge to the main source.A água está globalmente escarça e altamente competitiva entre muitos usuários. A ONU estima
que mais de 40% da população mundial deverá viver em áreas com graves problemas hÃdricos
até 2050. A única maneira previsÃvel para lidar com essa escassez é por meio da boa gestão dos
recursos disponÃveis e acessÃveis. O objetivo desse trabalho é promover o uso eficiente da água
através da medição sistemática do desempenho de um determinado sistema hÃdrico (water
system/WS) usando como ferramenta a eficiência sustentável (sustainable efficiency/Sefficiency). A
estrutura geral de Sefficiency — um indicador avançado de eficiência que considera o critério de
utilidade (caracterÃsticas de beneficência e qualidade da água) — foi sugerido e detalhado por
Haie, et al. em seu artigo de 2012. A fim de alcançar os resultados de eficiência finais após a
seleção de um WS, são necessários processos de aquisição e coleta de dados para caracterizar o
WS segundo considerações quantitativa, qualitativa e benéfica. Foram selecionados como WS
fazendas de cultivo de tomate localizadas em Davis City, Yolo County, na margem ocidental do
Rio Sacramento, o maior rio do estado da Califórnia, por causa dos graves e constantes perÃodos
de seca, além do notável valor económico da agricultura naquele local. Os resultados de Sefficiency
do WS sob consideração mostraram um desempenho relativamente ineficiente no nÃvel local de
