The Urban Nexus

The 21st century is the century of rapid urbanisation. Already today, more than half of the world’s population lives in urban areas, by 2050 it is expected to be two thirds. These people, with their basic requirements of water, energy and food, will determine future global resource consumption. Ensuring the supply of growing populations and their changing consumption patterns within global boundaries is a challenging task. The urban supply needs already exceed the capacities of the surrounding rural areas in many cases. Isolated sector planning is therefore no longer feasible. Instead, integrated and holistic approaches are crucial to overcome trade-offs and create synergies for sustainable urban development. This is what the Urban Nexus Approach seeks to achieve in order to contribute to greater resource efficiency.

HLP 2018 Side Event // Addressing Resilience through the Nexus of Water-Food-Energy – Cities as SDG Laboratories

The 2030 Agenda and the Sustainable Development Goals (SDGs) can only be achieved if they are pursued in an integrated manner. The way cities and human settlements are designed, planned, built, financed and governed has far-reaching implications for a life of dignity for all people and for the sustainable future of our planet. Globally, cities are increasingly recognised as transformative development actors, and their relevance for the implementation of the 2030 Agenda is acknowledged as not...

Urban Nexus Metabolism // Urban Metabolic Analysis of a Food-Water-Energy System for Sustainable Resources Management

By Ming-Che Hu, Chihhao Fan, Tailin Huang, Chi-Fang Wang and Yu-Hui Chen. Urban metabolism analyzes the supply and consumption of nutrition, material, energy, and other resources within cities. Food, water, and energy are critical resources for the human society and have complicated cooperative/competitive influences on each other. The management of interactive resources is essential for supply chain analysis. This research analyzes the food-water-energy system of urban metabolism for...

Towards Productive Cities // Environmental Assessment of the Food‐Energy‐Water Nexus of the Urban Roof Mosaic

By Susana Toboso‐Chavero, Ana Nadal, Anna Petit‐Boix, Oriol Pons, Gara Villalba, Xavier Gabarrell, Alejandro Josa, Joan Rieradevall. Cities are rapidly growing and need to look for ways to optimize resource consumption. Metropolises are especially vulnerable in three main systems, often referred to as the FEW (i.e., food, energy, and water) nexus. In this context, urban rooftops are underutilized areas that might be used for the production of these resources.

Special Issue // Systems Thinking and Urban Water Cycle Management

Equitable social, economic and environmental management of water resources and ecosystem services is central to planning for a world challenged by population growth and an increasingly variable climate. The evolution of urban areas to accommodate growing populations and in response to economic development results in profound changes to the natural water cycle and creates a modified urban water cycle. Among these, the Urban Nexus can be one answer to sustainable, future-proof water management.
