The water footprint provided a full methodology to operationalise the virtual water concept (the volume of water used along a supply chain to produce products and services). A key theme in the water footprint literature is the efficient allocation of water resources at the global scale given the feasibility of trading water intensive commodities from water rich to water poor areas: this is an economic problem of resource allocation between alternative and competing demands, albeit with a novel international component.Moreover, given that price signals indicating relative scarcity are usually either absent or distorted for water, it is also a problem that can be seen through the lens of environmental (or non-market) valuation. However, to date environmental valuation has not been used to inform the efficient use and allocation of water within and between the different locations encompassed by international supply chains. Methods: Drawing on an agri-food supply chain framework which we propose in this paper, we begin by conceptualising the economic values that accrue to water consumption (blue and green water) and degradation (grey water) at different points along a supply chain. Based on this conceptualisation, we assess the extent to which it is possible to approximate these economic values by relying on existing secondary data on the shadow value of water in different contexts. The use of secondary data in this way is known as benefit (or value) transfer. To achieve this, 706 unit estimates of the economic value of water are collected, standardised and reviewed encompassing off-stream water applications (agriculture, industry and municipal) and in-stream ecosystem services (waste assimilation, wildlife habitat, recreation, hydrological functions and passive uses).From this, a proposed methodology for valuing virtual water is presented and illustrated using the case study of global durum wheat pasta production. Results:The case study shows the total value of the virtual water used to produce one tonne of durum wheat pasta ($212). More importantly, the case study also highlights how variations in economic value between multiple locations where durum wheat is cultivated (Saskatchewan $0.10 m 3 , Arizona $0.08 m 3 and Baja California $0.24 m 3 ) indicate relative water scarcity and thus impact, as well as the potential for a more efficient allocation of virtual water. Conclusions:The main conclusion from this research is that when geographical disparities in the economic value of water use within a supply chain are accounted for, what was perhaps considered sustainable in volume terms, might not, in fact, represent the optimal allocation. However, future research opportunities

O Brasil é o quinto maior produtor mundial de coco e, embora a maior parte do cultivo seja convencional, a demanda por produtos de coco orgânico aumentou significativamente na última década, devido aos preços atrativos pagos pelos produtos orgânicos, bem como, ao entendimento da necessidade de proteger o meio ambiente. O objetivo deste estudo é explanar sobre o cultivo sustentável do coqueiro, suas possibilidades de aproveitamento e o comportamento do mercado no que concerne à sua comercialização. Para tanto, foi realizada consulta a trabalhos publicados relacionados ao tema; consulta à base de dados da Ceasa, Conab e ComexStat e consulta à legislação. O período de conversão de um cultivo convencional para orgânico do coco é de 18 meses, sendo necessário existir o Plano de Manejo Orgânico da propriedade. Os preços registrados obtidos com a venda do coco orgânico, tanto o seco quanto o verde, são superiores ao convencional, havendo oscilação no preço do coco ao longo do ano, em função das estações do ano e também influência do mercado internacional. Assim, o cultivo orgânico do coco tem se tornado atraente ao produtor. Apesar de ser um grande produtor, o Brasil importa coco seco desidratado, gerando queda nos preços no mercado nacional; entretanto, ao longo dos anos, tem se verificado aumento no consumo da água de coco, do leite, da farinha e do óleo de coco. Conclui-se que o mercado é promissor para cadeia produtiva do coco, sobretudo a cocoicultura orgânica, sendo importante, porém, que a produção no país atenda a demanda nacional e, especialmente, consolide e amplie a sua exportação.

“…The concept of the ecological footprint (EF) was proposed by William and introduced by Wackernagel in the field of assessing water resources [13,14]. The current research on EF W has concentrated on industrial production [15][16][17][18][19][20] and agricultural security [21][22][23][24], whereas quantitative assessments of urban water security are lacking [25]. However, the problem of water loss and polluted water have received increasing attention, which have made water companies, politicians, urban planners and other stakeholders use the concept of the ecological footprint of water to determine the direction of investment and policy implementation.…”

An Evaluation of the Sustainability of the Urban Water Resources of Yanbian Korean Autonomous Prefecture, China

The availability of water resources is crucial to maintaining the sustainability of urbanization. Calculating the ecological footprint of water (EFW) is one of the ways to realize the protection of water resources in the process of urbanization. The minor settlements in border areas have been the focus of China’s urbanization development but have rarely received research attention. The objective of this study was to develop an improved model of the ecological footprint of water (EFW) to assess the water security status of urban areas in Yanbian Korean Autonomous Prefecture (YKAP), and to demonstrate its authenticity compared with the traditional ecological footprint of water (EFW). The results showed that water pollution is the main reason for the increase in the EFW in each city, and the ecological water carrying capacity (ECW) showed strong fluctuations with the interannual variation in precipitation. Although the overall availability and quality of water resources are within safe limits, there are significant differences among cities, and water pollution poses a direct threat to the health and well-being of urban dwellers in some cities. Therefore, it is recommended that water resource management agencies adjust their water supply strategies based on the data from the EFW model, control wastewater discharge, improve their management systems and take urban economic development into account. This will significantly improve the sustainable management of water resources and ensure the health and well-being of urban residents.
