How do we bridge the city – nature gap and shape a new paradigm for cities and nature? By combining the natural sciences and the social sciences or integrating a quantitative, empirical foundation built around urban ecology with a mindset that values the qualitative sensitivities of sociology and phenomenology. Another way to think of this is a conversation between Rachel Carson and Jane Jacobs.
Cities present the greatest opportunity in the fight for low carbon development that promotes sustainability. Around the world we see the growth of “megacities” with developing world countries experiencing some of the greatest urbanization rates. The UN Population Fund estimates that more than half of the world’s population lives in cities today, and the number of urban dwellers is expected to continue to grow. NASA estimates that cities produce 70% of all fossil fuel CO2 emissions.
This post examines three steps that cities can follow to achieve emissions reductions.
Imagine what might happen if distributed power was installed at publicly owned facilities and resources. Every school, every police and fire station, along with critical intersections, could be equipped with an uninterruptable power supply in the form of PV panels and lithium-ion-based energy storage systems. Public spaces, critical street lights and businesses would remain illuminated.
In 2013, a Trust for Public Land study identified Cleveland Metroparks trails and parks as key economic drivers that contribute at least $855 million annually in economic benefits to Northeast Ohio. We also learned from this study that our trails and parks increase the value of nearby residential properties by $123 million.
Today, continued advances in low-cost sensors and the Internet of Things have enabled the next-generation of air quality monitoring that can provide decision makers and communities with accurate, high resolution data at costs orders of magnitude lower than traditional monitoring stations. Cloud-based platforms and machine learning can ensure these low-cost solutions are increasingly accurate and remain calibrated. Further, these new solutions are often designed for minimal maintenance to ensure they remain feasible for city budgets (or other operators) over the long term.
Up in floating cloud villages is where many of the world’s inhabitants live after coastlines are submerged under 58 feet of water. This is a book about the future written with the benefit of hindsight. We can predict, with a high degree of certainty, that: melting ice from Greenland and Antarctica, the warming oceans, and subsiding coastlines, will all contribute to rising sea levels. There is an inevitability to sea level rise that is palpable today. This is no ordinary work of fiction, but rather a novel set within an accurate scientific forecast. In 2140, Stanley Robinson does what a generation of environmental advocacy has failed to do: make climate change personal.
