There is the need to re-configure current urban water systems to achieve the objective of sustainable water sensitive cities. Stormwater represents a valuable alternative urban water source to reduce pressure on fresh water resources, and to mitigate the environmental impact of urban stormwater runoff. The selection of suitable urban stormwater harvesting sites is generally based on the judgeme...
The introduction of irrigation to agrarian areas involves several environmental changes that can be aggravated by physical and agronomic factors. The aim of this study is to analyze the spatiotemporal dynamics of the environmental impact on water resources that result from the transition of an agrarian basin into an irrigated area. During five hydrological years, a spatiotemporal comparison was...
This paper assesses the energy and water consumption practices of existing housing in Saudi Arabia, with the ultimate aim of establishing guidelines for delivering sustainable residential buildings in the near future. In order to achieve this aim the current status of a typical Saudi residence (i.e. an apartment complex) is investigated in terms of energy and water consumption using simulation ...
International agri-food trade has expanded rapidly during the past decades and changed considerably in structure with important implications, especially for developing economies. One of the main environmental concerns regarding international trade is the exploitation and redistribution of water resources. In this paper, we use the virtual water approach for analyzing the relationship between gl...
In this study, eight different surface water resources located in five villages of Gölcük, Kocaeli, were tested between June 1999 and 2000 to determine the NO 3 -N, Cl and pH values. Temporal variation in these parameters reflects changes in precipitation. The test results showed that the NO 3 -N, Cl and pH levels varied between 0.65-0.11 mgL, 0.54-0.04 mgL and 8.33-5.15, respectively. Data sho...
The study of the impact of economic activities on natural resources through global supply chains is increasingly demanded in the context of the growing globalization of economies and product fragmentation. Taking Spain as a case study and a sector with significant economic and environmental impacts, the agri-food industry, the objective of this work is two-fold. First, we estimate the associate...
The urgent demand of integrated water resources management has drawn attention to the issue of transnational water bodies that comprise exploitable resources for two or more countries. It is estimated that 50% of the global surface is lying on transboundary catchments and this percentage is continually increasing due to the creation of new nations, while around 40% of the earth’s population res...
Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we per...
