| Abstract: | It is used the horticulture industry in Spain. The author extends the existing methods for WF to more localised levels for crops grown partly in open systems and partly in plastic-covered houses with multi-seasonal harvesting and compared existing ecological methodologies with WF and argues that both life cycle analysis (LCA) and ecological footprint (EF) models could benefit from WF methods. These results show that the EU consumes 957,000 tons of Spanish fresh tomatoes annually, which evaporates 71 Mm3/yr of water and would require 7 Mm3/yr of water to dilute leached nitrates in Spain. The authors suggests that business now seek to report and address negative impacts on the environment. WF opens the door to complex water relationships and provides vital information for policy actors, business leaders, regulators and managers to their draw, dependence and responsibilities on this increasingly scarce resource. |
