The challenge of feeding nine billion people by 2050, in a context of constrained resources and growing environmental pressures posed by current food production methods on one side, and changing lifestyles and consequent shifts in dietary patterns on the other, exacerbated by the effects of climate change, has been defined as one of the biggest challenges of the 21st century. The first step to achieve food security is to find a balance between the growing demand for food, and the limited production capacity. In order to do this three main pathways have been identified: employing sustainable production methods in agriculture, changing diets, and reducing waste in all stages of the food chain. The application of an energy, water and food nexus (EWFN) approach, which takes into account the interactions and connections between these three resources, and the synergies and trade-offs that arise from the way they are managed, is a prerequisite for the correct application of these pathways. This work discusses how Life Cycle Assessment (LCA) might be applicable for creating the evidence-base to foster such desired shifts in food production and consumption patterns.

Well-functioning 'liveable' cities should be sustainable and their consumption of natural resources and production of waste must fit within the capacities of the local, regional and global ecosystems. It is increasingly becoming suggested that an Urban Metabolism (UM), approach could help city decision-makers (e.g. planners) take account of numerous critical influencing factors related to the inward outward flow(s) of natural resources (e.g. food, water and energy) and accumulation of waste. The paper identifies the precursory step for any UM study (Mass Flow Analysis - MFA) and applies it to a case study (Birmingham, UK) in order to show how it could contribute to the measurement, assessment and understanding of liveability, defined as 80% reduction in carbon (from 1990 levels); resource secure (an ethos of One planet living); with maintained or enhanced wellbeing. By provided focus upon an individual resource stream (i.e. water) at multiple scales (city to individual) it is shown that MFA can be used as a starting point to develop realistic and radical engineering solutions. However further work is required for it to be truly reflective of broader aspects of urban liveability.
CONFERENCE-ARTICLE 5 Reads 0 Citations Rainwater Harvesting: Trade-offs Between Pluvial Flood Risk Alleviation and Mains Water Resource Savings Dexter Hunt, Chris Rogers Published: 31 October 2014

Stormwater run-off generally refers to pluvial, i.e. rainfall related, water that does not soak into the ground at the point at which it falls. The volume and timing of stormwater run-off, specifically from roof tops is highly important to urban flood control and its capture has the potential for non-potable uses within (e.g. for WC flushing and for washing machines) and outside the home (e.g. car washing and garden watering). The former runs a risk of flash floods where local and downstream stormwater (or combined sewer) systems become overburdened in times of extreme rainfall events. The later will influence potential future urban water supplies, which is particularly important at time(s) where mains water availability is scarce (e.g. times of drought or when the national demand for water in the UK increases beyond supply capabilities) population. Rainwater harvesting (RWH) systems can benefit flood risk and water supply however their ability to do either / both is dependent on the subtleties of filling and emptying (i.e. stored water volume or spare storage capacity) which are not fully understood, particularly in peak flow events. Through the use of five years worth of daily rainfall data for Birmingham (2007 - a record breaking year for UK flooding, to 2011) these subtleties are investigated through a sensitivity type analysis of tank size, occupancy rates and technology efficiency. The results show that RWH tanks sized according to BS8515 would not have been capable of capturing rainfall that fell in peak flow events. Moreover not all yearly non-potable demands would have been met. If tanks were over-sized by a factor of 3.0 (i.e. use the larger of 15% yearly non-potable demands or rainfall) this would have been sufficient to meet all demands and eliminate roof-top run-off.

CONFERENCE-ARTICLE 8 Reads 0 Citations Greywater Recycling Systems in Urban Mixed-Use Regeneration Areas: Economic Analysis and Water Saving Potential Sara Zadeh, Diane Lombardi, Dexter Hunt, Christopher Rogers Published: 29 October 2012

Greywater (GW) recycling for non-potable uses such as toilet flushing is a management strategy to meet urban water demand with substantial water saving. This paper proposes a system that collects GW from residential buildings and recycles it for toilet flushing in both residential and office buildings. The total cost and water saving of standard sanitation technology were compared with 5 other options requiring less or no potable water use in toilets. Scenarios compare: no GW, individual GW, and shared GW systems with and without low-flush appliances. Typical residential and office buildings in urban mixed-use regeneration areas in the UK were used for these analyses. The results implied that constructed wetland treatment technology with standard appliances is more economically and environmentally viable than other scenarios. By increasing the water and wastewater price, shared GW systems with and without low-flush appliances were viable options within highly water efficient domestic and office buildings.

The achievement of a less unsustainable future requires a multi-dimensional approach that addresses a range of \'issues\' (i.e. the sustainability indicator spectrum; demographics through to water) within a bounded yet diverse \'space\' (i.e. global through to local scale) over \'time\' (i.e. current and future generations; their needs and aspirations). Futurescenarios provide challenging, plausible and relevant stories about how the future, typically within 5 to 100 years, could unfold. As neither forecasts nor predictions and unconstrained by the requirement for substantiating how one gets from here to there they allow a range of sustainability issues to be challenged at different scales in future worlds. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenario visions published within the literature over the period 1997-2011. Whilst it is evident that some comparisons have been undertaken there is little evidence to substantiate converging rather than diverging themes from which an overarching scenario archetypal could be drawn. This is significant shortfall for those who wish to test the principles of sustainability / resilience against a generic scenario set, rather than derive yet more scenarios to add to the list already identified. In fulfilling this research need it has been possible to identify, based upon their scenario narratives, a sub-set of 150 scenarios that can be categorised according to three world types (i.e. Business as usual, Barbarisation and Great Transitions) and six scenarios; two for each world type (i.e. Policy Reform - PR, Market Forces - MF, Breakdown - B, Fortress World - FW, Eco-Communalism - E and New Sustainability Paradigm – NSP respectively) first proposed by the Global Scenarios Group (GSG) in 1997. It is suggested that four of these (MF, PR, NSP and FW) are sufficiently distinct to facilitate active stakeholder engagement and allow sustainability/resilience to be tested over a broad range (e.g. high to low technological efficiency). Moreover this archetypal scenario set is accompanied by a well-established, internally consistent set of narratives that provide a deeper understanding of the key fundamental drivers (e.g. economic, environmental, social, technological, political and organisational) that could bring about realistic world changes through a push or a pull effect. This is testament to the original concept of the GSG scenarios and their development and refinement over a 20 year period.
