In the Bulgarian capital city of Sofia, many people prepare pickled vegetables (zimnina) for the winter months. This widespread practice touches on basic service issues like water and energy supply, as well as food provisioning for the city’s most vulnerable residents, explains Ralitsa Hiteva from the Resnexus project.
This April, the second Nexus Conference will focus on the links and trade-offs between water, energy, and food—the “nexus”—in urban areas. Cities are at the forefront of the climate challenge and the heart of the global economy, so they are critical to implementing an integrated approach to meeting the SDGs and building climate resilience.
Windhoek—the capital city of Namibia, the most arid country in Sub-Saharan Africa—has long met its severe water challenges through innovation. But its growing population is increasing its demand for water while climate change exacerbates scarce supplies. On the occation of World Water Day 2018, Pierre van Rensburg highlights the city's innovative augmentation strategies to keep the crisis from becoming a catastrophe.
The "Urban Nexus" is a theoretical and technical approach to integrated urban development. It introduces innovative and environmentally-friendly engineering solutions to improve the physical infrastructure of cities, and also promotes people-centered development. Our authors Ruth Erlbeck and Ralph Trosse describe how a low-cost, climate change resilient pilot house was built in the Philippines as part of the Nexus project.
