Urban agriculture has the potential to play an important role in the global food, energy, and water (FEW) nexus. This type of agriculture involves growing food, energy, and other resources in urban areas, such as rooftop gardens, vertical farms, and green walls. Urban agriculture is becoming increasingly popular due to its ability to increase local food production, reduce energy costs, and conserve water. With the right technology and policies in place, urban agriculture can help cities become more sustainable and resilient. By promoting urban agriculture, cities have the potential to reduce their dependence on external energy sources, increase food security, and reduce water use. Furthermore, urban agriculture can create jobs and spur economic development in local communities. In short, urban agriculture is an important tool for cities to address the FEW nexus, and should be strongly supported and encouraged.
