Cities are often thought of as concrete jungles. But under all that concrete is a whole lot of soil: complex mixtures of minerals, water, air, and organic matter that perform many critical functions.
We build on top of soil, we grow grass and gardens in it, we depend on it to filter pollutants and capture runoff. Yet soils in cities have often been neglected.
That’s now changing. As our world becomes increasingly urbanized, there is growing recognition among scientists, city planners, and urban gardeners that city soils require just as much attention and care as those in our farmlands.
Explore these pages to learn more about the roles that soils play in cities, and how you can help protect and nurture this vital urban resource.
