“…For instance, Miara et al (2014) showed how scaling-up production of algal biofuel requires land, water, fertilizer and energy inputs and, in the process, triggers changes to a region's food production capacity, and energy and water demands. The provision of water (Bizikova et al 2013), energy (Bazilian et al 2011, Wagner and Breil 2013, Miara et al 2014, and food (Hoff 2011) all served as FEW triggers of system-wide change. Often there are multiple triggers: simultaneous growth in demand for FEW.…”

Essential for society to function, the production and consumption of food, energy, and water (FEW) are deeply intertwined, leading to calls for a nexus approach to understand and manage the complex tradeoffs and cascading effects. What research exists to date on this FEW nexus? How have scholars conceptualized these interactions at the urban scale? What are some promising approaches? Where are the research gaps? To answer these questions, we conducted a quantitative review of the academic literature on the FEW nexus (1399 publications) over more than four decades , followed by in-depth analysis of the most influential papers using an evaluation matrix that examined four components: 1) modeling approach; 2) scale; 3) nexus 'trigger'; and 4) governance and policy. Scholars in the fields of environmental science predominated, while social science domains were underrepresented. Most papers used quantitative rather than qualitative approaches, especially integrated assessment and systems dynamics modeling although spatial scale was generally recognized, explicit consideration of multi-scalar interactions was limited. Issues of institutional structure, governance, equity, resource access, and behavior were also underdeveloped. Bibliometric analysis of this literature revealed six distinct research communities, including a nascent urban FEW community. We replicated the analysis for this urban group, finding it to be just emerging (80% of papers have been published since 2010) and dominated by scholars in industrial ecology. These scholars focus on quantifying FEW flows of the urban metabolism in isolation rather than as a nexus, largely ignoring the political and socio-economic factors shaping these flows. We propose the urban FEW metabolism as a boundary object to draw in diverse scholarly and practitioner communities. This will advance research on complex FEW systems in four key areas: (1) integration of heterogeneous models and approaches;(2) scalar linkages between urban consumption and trans-boundary resource flows;(3) how actors and institutions shape resource access, distribution and use; and (4) co-production of knowledge with stakeholders.

“…Constructed wetlands, which are artificially created wetland ecosystems to treat-e.g., collected rainwater or wastewater, similarly to ponds and creeks-are also a possible solution for enhancing ecology and aesthetic value, enabling water retention for reuse for irrigation. The idea of linking water body and other open green spaces in a "blue-green infrastructure" is now recognized as part of cities planning strategy [36,37]. Local spatial management plans determine the indicators, forms, and functions of development, primarily the details of land use (including in areas excluded from construction) and the required percentage share of biologically active surfaces, providing opportunities to influence water management and mitigate the effects of flooding.…”

Abstract:Water resources conservation corresponding to urban growth is an increasing challenge for European policy makers. Water footprint (WF) is one of the methods to address this challenge. The objective of this study was to develop a simplified model to assess the WF of direct domestic and non-domestic water use within an urban area and to demonstrate its effectiveness in supporting new urban water management strategies and solutions. The new model was tested on three Central European urban areas with different characteristics i.e., Wroclaw (Poland), Innsbruck (Austria), and Vicenza (Italy). Obtained WFs varied from 291 dm 3 /(day·capita) in Wroclaw, 551 dm 3 /(day·capita) in Vicezna to 714 dm 3 /(day·capita) in Innsbruck. In addition, WF obtained with the proposed model for the city of Vicenza was compared with a more complex approach. The results proved the model to be robust in providing reasonable results using a small amount of data.

“…Therefore, these services are determined and limited by both an expansion of cities and the state of ecosystem itself (Wagner & Breil 2013). Regarding a spatial expansion, a sensitive urban planning reducing the external impacts on UC ecosystems, could be of a great help.…”

The risks of accelerated runoff and its larger amounts brought by urbanisation include increased flood flows and pollution of downstream ecosystems. One of the most significant permanent effect of urban sprawl is soil sealing, which alters natural infiltration and runoff. In addition to imperviousness, the increased runoff from sealed and compacted surfaces results in increased sedimentation of stream ecosystems with contaminants. In most urban planning strategies, water related ecosystems have already become the fundamental components of the integrated urban landscape management, but still have been referred to as objects of protection or rehabilitation; not as management tools. This paper shows how soil sealing significantly affects urban environment and urban ecosystems health. It also demonstrates significant impacts of a city on downstream ecosystems. Data obtained from orthophotomap vectorization showed that the model urban catchment is relatively highly urbanized. 45% of model area is sealed mainly with buildings (40.41%), streets (31.01%), and parking lots (25.28%). Compared to natural basins, urban runoff is 64 times higher and carries a significant amount of pollutants.
