“…The HRB is located in arid and semi-arid regions with high potential evaporating capacity. We also find that the VWC values of livestock products in HRB are generally higher than those reported in Chapagain and Hoekstra (2004) and Liu and Savenije (2008). Especially for beef, its VWC value is 1.6 times the value calculated by Chapagain and Hoekstra (2004).…”

“…At the sector level, calculated the WF of domestic, industrial and agricultural sectors in Spain and found that the inefficient allocation of water resources and mismanagement in the agricultural sector lead to water scarcity in Spain. At the national level, the WF of China (Liu and Savenije, 2008;Ma et al, 2006), India (Kampman et al, 2008), Indonesia (Bulsink et al, 2010), Netherlands (Van Oel et al, 2009), UK (Chapagain and Orr, 2008) and France (Ercin et al, 2012) have been assessed. At the global level, WF of goods and services consumed by humans have been quantified by Hoekstra and Chapagain (2007) and .…”

Abstract. Increasing water scarcity places considerable importance on the quantification of water footprint (WF) at different levels. Despite progress made previously, there are still very few WF studies focusing on specific river basins, especially for those in arid and semi-arid regions. The aim of this study is to quantify WF within the Heihe River Basin (HRB), a basin located in the arid and semi-arid northwest of China. The findings show that the WF was 1768 million m 3 yr −1 in the HRB over [2004][2005][2006]. Agricultural production was the largest water consumer, accounting for 96 % of the WF (92 % for crop production and 4 % for livestock production). The remaining 4 % was for the industrial and domestic sectors. The "blue" (surface-and groundwater) component of WF was 811 million m 3 yr −1 . This indicates a blue water proportion of 46 %, which is much higher than the world average and China's average, which is mainly due to the aridness of the HRB and a high dependence on irrigation for crop production. However, even in such a river basin, blue WF was still smaller than "green" (soil water) WF, indicating the importance of green water. We find that blue WF exceeded blue water availability during eight months per year and also on an annual basis. This indicates that WF of human activities was achieved at a cost of violating environmental flows of natural freshwater ecosystems, and such a WF pattern is not sustainable. Considering the large WF of crop production, optimizing the crop planting pattern is often a key to achieving more sustainable water use in arid and semi-arid regions.

“…In classical water scarcity analysis there was a focus on blue water resources, with limited account for spatial and temporal variability and no account for green water, reuse, international distribution of resources and trade in water dependent products, the different types of water needs (drinking water, agricultural, industrial, environmental, etc.) and the impacts of population growth, land use changes, climate change and changing lifestyles (Savenije, 1998(Savenije, , 2000Liu and Savenije, 2008). A number of important innovations emerged relatively recently.…”

Abstract. This paper reviews the changing relation between human beings and water since the Industrial Revolution, a period that has been called the Anthropocene because of the unprecedented scale at which humans have altered the planet during this time. We show how the rapidly changing world urges us to continuously improve our understanding of the complex interactions between humans and the water system. The paper starts by demonstrating that hydrology and the science of managing water resources have played key roles in human and economic development throughout history; yet these roles have often been marginalised or obscured. Knowledge of hydrology and water resources engineering and management helped to transform the landscape, and thus also the very hydrology within catchments itself. It is only fairly recent that water experts have become conscious of such mechanisms, exemplified by several concepts that try to incorporate them -integrated water resources management, eco-hydrology, socio-hydrology. We have reached a stage at which a more systemic understanding of scale interdependencies can inform the sustainable governance of water systems, using new concepts like precipitation sheds, virtual water transfers, water footprints, and water value flow.

“…The magnitude of the challenge is outlined in the Sustainable Development Goals, which set a target of zero hunger globally whilst at the same time drastically reducing impacts of food production on aquatic and terrestrial ecosystems as well as the climate system (United Nations, 2015). Food security and water security are inextricably intertwined, with variability in agricultural production impacting water resource use and vice versa (Liu and Savenije, 2008). Food trade, both international and domestic, also plays a central role in determining water use because when we trade food, we trade the water embedded in the production of that food (Fader et al, 2013;Hoekstra and Mekonnen, 2012).…”

A framework for modelling the complexities of food and water security under globalisation

Abstract. We present a new framework for modelling the complexities of food and water security under globalisation. The framework sets out a method to capture regional and sectoral interdependencies and cross-scale feedbacks within the global food system that contribute to emergent water use patterns. The framework integrates aspects of existing models and approaches in the fields of hydrology and integrated assessment modelling. The core of the framework is a multi-agent network of city agents connected by infrastructural trade networks. Agents receive socio-economic and environmental constraint information from integrated assessment models and hydrological models respectively and simulate complex, socio-environmental dynamics that operate within those constraints. The emergent changes in food and water resources are aggregated and fed back to the original models with minimal modification of the structure of those models. It is our conviction that the framework presented can form the basis for a new wave of decision tools that capture complex socio-environmental change within our globalised world. In doing so they will contribute to illuminating pathways towards a sustainable future for humans, ecosystems and the water they share.
