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.

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...

Quantifying the Sustainability of Water Availability // Water-Food-Energy-Ecosystem Nexus in the Niger River Basin

Water, food, energy, and the ecosystems they depend on interact with each other in highly complex and interlinked ways. These interdependencies can be traced particularly well in the context of a river basin, which is delineated by hydrological boundaries. Using the example of the Niger River Basin in West Africa, this study assesses the impact of climate and human/anthropogenic changes on the water, energy, food, and ecosystem sectors. It characterizes the resulting trade-offs through a set of...
