Modelling Tool // An Alternative to Market-Oriented Energy Models: Nexus Patterns across hierarchical Levels

By Louisa Jane Di Felice, Maddalena Ripa and Mario Giampietro. Energy is entangled with nexus elements, including water, land, emissions and labour. At the science-policy interface, large market-oriented energy models dominate as the tool to inform decision-making. The outputs of these models are used to shape policies, but strongly depend on sets of assumptions that are not available for deliberation and gloss over uncertainties. Taking an approach from complexity, the authors propose an...

Water-Energy-Food Nexus Literature Review // A Review of Nexus Literature and ongoing Nexus Initiatives for Policymakers

This literature review provides an overview of key Nexus concepts and tools that can be applied in policy and practice. It aims to be a resource for professionals responsible for Nexus relevant decisions either in planning, financing or implementation. It aims to provide an overview of the literature covering the WEF Nexus topic, with a discussion on how the approach can be effectively implemented on the ground. The review also aims to summarise ongoing WEF Nexus initiatives and regional...

Profil Nexus // Bassin du Niger

Le bassin du fleuve Niger en Afrique de l’Ouest et Centre Afrique couvre une superficie totale de 2,13 millions de km² et plus de 130 millions de personnes habitent dans le bassin, provenant de neuf pays: Bénin, Burkina Faso, Cameroun, Côte d’Ivoire, Guinée, Mali, Niger, Nigeria et Tchad. Sept des neuf pays du bassin figurent parmi les 20 pays les plus pauvres du monde, avec de grandes disparités de revenus dans les pays les plus riches du bassin. La plupart d’entre eux sont confrontés à une...

Interdisciplinary Demand Modelling // Envisioning Surprises: How Social Sciences could help Models represent ‘Deep Uncertainty’ in Future Energy and Water Demand

By Maria Sharmina, Dana Abi Ghanem, Alison L. Browne, Sarah Marie Hall, Josephine Mylan, Saska Petrova, Ruth Wood. This paper explores how future energy and water demand is modelled, using the term modelling to encompass both quantitative and qualitative methods of envisioning future demand, and offers ideas on improving the modelling techniques, as a basis for supporting long-term strategic planning.

Energy-Water Nexus // Viability of Wind Turbine to Desalinate Water for Drinking

By Ngwamah Hyelda Moses. This study aims at assessing the viability of wind energy in Burutu, Nigeria, to desalinate water through reverse osmosis technology. Burutu has been identified with shortage of drinking water as a result of salt water intrusion from the ocean. Four analysis were carried out: First was the estimation of wind speed in m/s at the height of 120m. Second analysis was the calculation of energy generation in kWh. Third analysis was calculation of volume of water in m^3 which...

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...

Nexus Profile // Niger Basin

The Niger River Basin (NRB) in West and Central Africa covers a total area of 2.13 million km2 and its active basin is home to over 130 million people throughout nine countries: Benin, Burkina Faso, Cameroon, Chad, Ivory Coast, Guinea, Mali, Niger, and Nigeria. All 9 riparian states are in the bottom third of the 189 countries according to the UNDP’s Human Development Index (2018), with 5 in the last 15. Most of them face rapid population growth (an estimated annual average of 3.2%) and...

Nexus Country Profile // Peru

Peru is located from 0°S to 18°S in western South America; it borders Ecuador and Colombia to the north, Brazil to the east, Bolivia to the southeast, Chile to the south, and the Pacific Ocean to the west. Three contrasting geographic regions exist in the country: Coastal region: a long, desertic plain with a very dry climate. The region stretches along the coast on the west of the country and is approximately 50-100 km wide. The highlands: the mountainous region running down the middle of the...

Tool // Climate, Land (Food), Energy and Water Systems Approach (CLEWs)

The Climate, Land (Food), Energy and Water systems approach (CLEWs) focuses on assessing interlinkages between resource systems in order to understand how these are related with each other, where pressure points exist, and how to minimize trade-offs while potentiating synergies. The framework is applicable to different geographical scales, from global, to regional, national and urban levels. ​The tool is used and actively developed in partnership with UNDESA and the UNDP.

Measuring the Water-Energy-Food Nexus // The Case of Latin America and the Caribbean Region

This paper presents an actual overview of the current state of the water-energy-food (WEF) nexus in Latin American and The Caribbean countries. The analysis is divided in terms of water, energy and food production for each country. The proposed WEF Nexus index comprises three key indicators per sector, considering availability, access, and stability of sector’s resources.
