The future of our cities depends on our better understanding of the many layers that comprise it as a system. Without that understanding we cannot hope to efficiently and effectively manage the resources and many subsystems that make a city what it is, like transportation, water distribution and sewage networks, electricity grids and healthcare systems.
Water-energy-food nexus is at the heart of the problems and opportunities that cities are faced with. We, at Stage AI, are passionate about making cities more sustainable and ‘smarter’, and therefore we have focused most on the areas of water and energy systems analysis and management. In these blog series we intend to share a bit of the problems that we see are present in those systems across cities, as well as how our solutions can help in resolving those complex issues that influence us all, no matter where on Earth we reside.
One of greatest threats globally is that of a global water crisis which some argue is on the way and some claim is already here. Water crisis is already present around the planet from China and India, to the Middle East and North Africa, to California to Chile. Water supply and demand are diverging, leaving us with a projected gap in supply of 40% by 2030 around the globe, because of increased urbanization and many other socio-economic factors. By 2025, half of the world’s population will be living in water-stressed areas, at the same time, many people already live without adequate water provision and risk of diseases. Climate change adds more strain to the overall picture that will deeply affect our current water systems. Changes in rainfall patterns , changes in the chemical makeup of the worlds’ oceans and our water supply systems will have to adapt to this changing context, while at the same time providing more people with less reserves of water.
