Nexus Blog // The Internet of Things as a Key Enabler for Quantifying the Water, Energy and Food Nexus

By Harris Moysiadis. This article explores how the Internet of Things concept could facilitate the implementation of the water, energy and food nexus. The author introduces the H2020 project “Innovative eco-technologies for Resource Recovery from Waste-water” (INCOVER). It is argued that platforms and technologies offered by the Internet of Things could have a profound role in quantifying, visualising and sharing important data that would help state and non-state actors to plan, develop and...

Informing Regional Water-Energy-Food Nexus with System Analysis and Interactive Visualization // A Case Study in the Great Ruaha River of Tanzania

In sub-Saharan Africa, water resources are scarce and subject to competing uses – especially for agricultural production, energy generation, and ecosystem services. These water intensive activities in the Usangu plains and the Ruaha National Park in southern Tanzania, present a typical case for such water competition at the water-energy-food nexus. This study tries to decipher the coupled human-nature interactions in the Great Ruaha River basin and effectively communicate the results to...

Case Study Thailand // How Chiang Mai’s Wastewater Utility is Building Capacity on Sustainable and Innovative Solutions to reduce its Carbon Footprint.

This case is part of a case study series, where the Water-Energy-Climate Nexus approach supports the transition towards a more sustainable and low-carbon urban management. In the city of Chiang Mai, the WaCCliM project supports the Wastewater Management Authority (WMA) in assessing opportunities to reduce its carbon footprint. A baseline study identified the leaks of untreated wastewater, caused by fractured pipes in the wastewater collection system, as the main source of greenhouse gas (GHG)...

Case Study Peru // Planning locally, impacting globally – How Water and Wastewater Utilities in Peru are Facing Climate Change

This case is part of a case study series, where the Water-Energy-Climate Nexus supports the transition towards a more sustainable and low-carbon urban management. How to ensure water and sanitation services delivery under a climate change context? The climate change mitigation and adaptation plans (PMACC; Planes de Mitigación y Adaptación al Cambio Climático) are tools to address this challenge. PMACC identify main carbon emissions sources and higher climate risks throughout the urban water...

Case Study Mexico // How Guanajuato’s Water and Wastewater Utilities are tackling Climate Change through Efficiency Optimization and Renewable Energy Production

This case is part of a case study series, where the Water-Energy-Climate Nexus supports the transition towards a more sustainable and low-carbon urban management. In San Francisco del Rincón, two utility companies, SITRATA (Servicio de Tratamiento y Deposición de Aguas Residuales) and SAPAF (Sistema de Agua Potable y Alcantarillado de San Francisco), are collaborating on projects to improve their services and lower their greenhouse gas (GHG) emissions. SITRATA manages wastewater, while SAPAF is...

Case Study Jordan // How Madaba’s Water and Wastewater Utility is finding innovative Solutions to operational Burdens while reducing Carbon Emissions

This case is part of a case study series, where the Water-Energy-Climate Nexus supports the transition towards a more sustainable and low-carbon urban management. In Madaba, the Miyahuna Water Company conducted a study to determine and address greenhouse gas (GHG) emissions from its operations. Miyahuna operates both water and wastewater systems in the city. The GHG assessment was conducted using the Energy Performance and Carbon Emissions Assessment and Monitoring (ECAM) Tool. This highlighted...

The Nexus Concept Integrating Energy and Resource Efficiency for Policy Assessments // A Comparative Approach from Three Case

By Floor Brouwer, Lydia Vamvakeridou-Lyroudia, Eva Alexandri, Ingrida Bremere, Matthew Griffey, Vincent Linderhof. As the world increasingly runs up against physical constraints of energy, land, water, and food, there is a growing role for policy to reduce environmental pressures without adversely affecting increases in prosperity. There is therefore a need for policy makers to understand the potential trade-offs and/or synergies between the uses of these different resources, i.e., to encompass...

Agua, Producción de Alimentos y Energía // La Experiencia del Nexo en Chile

Por Humberto Peña. El presente estudio analiza este Nexo en el caso de Chile. Con ese propósito, se revisa la evolución de las políticas públicas y los marcos institucionales relacionados con la gestión del agua, y el desarrollo del riego y de la energía eléctrica. En el análisis se distingue entre: un período inicial; otro donde el Estado fue el motor del desarrollo; un tercero con un predominio del mercado; y, finalmente, uno donde se busca un nuevo equilibrio entre el interés público y los...

Casos de Buenas Prácticas en Chile y el Perú // La Eficiencia en el Uso del Agua y la Energía en los Procesos Mineros

Por José Luis Lewinsohn and René Salgado. El uso del agua y la energía en los procesos mineros, en especial en los países andinos, planteará múltiples desafíos en el futuro, ya que la necesidad de capturar la renta derivada de la actividad extractiva exigirá, entre otros aspectos, el uso intensivo de estos insumos. En este documento se presenta el análisis de dos casos de estudio de la industria minera en Chile y el Perú.
