Welcome to this deck on sustainable urban living. As more of the world's population moves into cities, making them sustainable is one of the biggest challenges we face. A sustainable city aims to meet the needs of people today without compromising the ability of future generations to meet their own needs. In your exam, you'll need to explain and evaluate strategies that help cities achieve this goal.

Let's start with water conservation. Many cities, especially in drier climates or with large populations, face water shortages. Sustainable water management involves reducing consumption and using water resources more efficiently. This can include everything from fixing leaks in pipes to encouraging residents to use less water at home.

Another key area is energy conservation. Cities consume vast amounts of energy, often from burning fossil fuels, which contributes to climate change. Sustainable cities focus on reducing energy demand and switching to renewable energy sources. This is a great point to make in an exam when discussing environmental sustainability.
