“…Thus, volume to assimilate phosphate can assimilate the other two pollutants. Therefore, phosphate is currently the critic pollutant for surface water in Segura River Basin, as occurs in other basin in Spain (Morera et al, 2015). On the other hand, in groundwater bodies the critic pollutant is nitrate, since it is the only limited pollutant.…”

“…• Pollutant discharges carry more than one substance -the GWF value being determined by the critical pollutant (Hoekstra et al, 2011;Wang and Wu, 2014;Morera et al, 2015), for this substance requires the largest water volume in order to be assimilated. • The temporary nature of pollutant discharges is due to the monthly simulation of the anthropised water cycle for a period of time, at least one year.…”

“…In scarcity years the volume of water desalination is highest, whereas in wet years the volume decreases due to the natural water resources are used instead of desalinated water, which is more expensive. This study incorporated the three main pollutants discharged by urban wastewater and irrigation return flows: organic matter, phosphate and nitrate (Morera et al, 2015). The latter two are on the list of principal pollutants of the EU (EC, 2000), and a specific directive on agriculture-related nitrate was drafted (EC, 1991).…”

“…Similarly, the WFs of different regions and countries have also been evaluated [15], [16]. WFs have also been used to assess the production of hydropower energy [17] and biofuels [18], [19], amongst other applications [20]- [23]. For the most part, previous studies of this sort conducted global WF analyses of crop production, but a few recent studies focused, instead, on regional WFs, with only a few of studies having provided complete calculations of total WFs.…”

Abstract. This paper explores the water footprint (WF) of paddy rice and the nexus of waterland-food (rice) in Taiwan. The research results indicate that the average annual rice WF for the years 2005-2014 was about 7,580 m 3 /ton, of which 80% was blue, 17% was green, and 3% was grey. This average annual footprint was about 5.7 times larger than the 2000-2004 average annual WF of rice for countries around the globe of 1325 m 3 /ton, of which 48% was green, 44% was blue, and 8% was grey. The blue WF is the most important source of water for rice production in Taiwan. The water consumption of the second crop is higher than that of the first crop. The water use efficiency in the southern region of Taiwan is the best, while the northern part of Taiwan exhibits relatively high inefficiency. The rates of change in cultivated land and rice production in Taiwan are decreasing in a stable manner. However, the annual rate of change in the rice WF is unstable. The nexus of land, water, and food should be taken into consideration to protect water availability, maintain agricultural production, and avoid land degradation. The results could offer useful information for agriculture policy and water resource management.

“…The bottom-up approach based on detailed process information has been widely used to analyze the VW of products and WF of one process or within a certain geographical region [8,[15][16][17][18]. However, this approach fails to distinguish intermediate water use from final water use [13].…”

Given increasing concern about seeking solutions to water scarcity and pollution (WSP), this paper is intent on developing significant assessment indicators as decision variables for providing reference for policy proposals on the mitigation of WSP. An indicator package consisting of footprints of freshwater consumption (FC) and water pollutant discharge (WPD), virtual contents of freshwater and water pollutants, and inter-sectoral linkages in terms of industrial production, FC and WPD has been newly set up based on an extended input-output model. These indicators allow to provide specific and well-structured analysis on FC, WPD and the economy as well as their implicated interrelationships. The Source Region of Liao River located in northeastern China was selected as an empirical study area to apply the indicator package. The results indicate that farming and production of electricity industries are major contributors to FC; farming and breeding industries, and households are major contributors to WPD. The study area exports a large amount of net virtual total nitrogen, total phosphorus and chemical oxygen demand (29.01ˆ10 3 t, 4.66ˆ10 3 t, 60.38ˆ10 3 t, respectively). Farming and breeding industries are the sectors whose production could be constrained to contribute to mitigating WSP without excessive negative impacts on the economy. Two categories of policies have been proposed to mitigate WSP based on the analysis of the indicator package. One is to introduce direct water pollutant treatment and water-saving policies to the target sectors; the other is to adjust industrial structure. The integrated indicator package developed and the methodology presented are expected to provide policy researchers and decision makers with references for more sound water management.
