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.

The food/water/energy nexus is the study of the interactions and connections between these three resources, the synergies and tradeoffs that arise from the way they are managed, and the potential areas of conflict. The core of nexus thinking is that no good results can be achieved from considering these resources independently, which means that food security cannot be achieved in a context of either/both water or/and energy insecurity. All three elements have to be assured to foster sustainability, resilience, prosperity and peace. In this paper attention is focused on the challenges posed by this nexus on achieving food security, which is embodied in the first Millennium Development Goal (MDG), which seeks to halve the number of hungry people in the world between 1990 and 2015. The primary aim of the paper is to identify how the nexus mentality underlies most of the pathways that have been proposed to achieve this goal. It argues that significant shortfalls exist and need to be addressed: there is still no generally accepted definition, and identifiable metrics for assessing the extent to which a food system fosters food security are lacking. Such metrics are necessary when evaluating alternative strategies and negotiating trade-offs therein.
