JPI Urban Europe SUGI - Waste Food-Energy-Water Urban Living Labs - Mapping and Reducing Waste in the Food-Energy-Water Nexus (WASTE FEW ULL)

少浪费城市生活垃圾项目的目的是开发和测试国际上适用的方法，以确定城市-地区的食物-能源-水关系中的低效率。我们将通过在四个城市地区--英国(布里斯托尔)、荷兰(鹿特丹)、南非(西开普省)和巴西(坎皮纳斯)--的工业/公民社会主导的城市生活实验室(ULL)的国际网络开展这项工作。挪威和美国的合作伙伴将提供对潜在影响的经济评估，以及以影响为主导的公共教育、推广和传播。浪费发生在食品、能源和水系统中；在这些系统的交界处，浪费显著增加了我们有限资源的过度消耗(粮农组织，2017年)：粮食(例如在食物储存中损失的能量)、能源(例如用于清洁水)和水(例如在污水中损失的营养物质)。资源稀缺不仅是一个效率问题，而且是一个获取、分配和平等的问题(Exner等人，2013年)。每种城市环境都有不同的压力和机会(Ravetz，2000)。因此，少浪费城市土地利用项目的重点不是具体的下游挑战，而是上游进程，通过这些进程，城市可以确定、测试和扩大可行的解决方案，以减少每种情况下最紧迫的低效问题。

The aim of the WASTE FEW ULL project is to develop and test internationally applicable methods of identifying inefficiencies in a city-region's food-energy-water nexus. We will undertake this through an international network of industry/civic society-led Urban Living Labs (ULL) in four urban regions - UK (Bristol), Netherlands (Rotterdam), South Africa (Western Cape) and Brazil (Campinas). Partners in Norway and the USA will provide economic valuations of potential impact, and impact-led public education, outreach and dissemination.Waste occurs across food, energy and water systems; at the interface of these systems, waste increases significantly the over-consumption of our limited resources (FAO, 2017): food (e.g. energy lost in food storage), energy (e.g. used to clean water) and water (e.g. nutrients lost in sewage). Resource scarcity is not only a matter of efficiency, but of access, distribution and equality (Exner et al, 2013). Each urban context has different pressures and opportunities (Ravetz, 2000). The focus of the WASTE FEW ULL project is therefore not so much on the specific downstream challenges, but on upstream processes by which cities can identify, test and scale viable and feasible solutions that reduce the most pressing inefficiencies in each context.
