Think of a community as a volleyball (or at least try to). Instead of air, it’s filled with all of those things that make up a community – people and their skills and connections; businesses and financial capital; buildings and the natural environment; a culture derived from its history, its people and their beliefs, and its mechanisms for making decisions and acting – what are called the community capitals.
Let me torture this analogy just a little further. No matter how well-sealed the volleyball is, there will still be small leaks, i.e., the community will tend to lose capital over time. Infrastructure may age; bureaucratic regulations may take the place of governance. The ball may also be used hard, opening more serious leaks: social tensions may tear the community’s social fabric; key people may move away. If I don’t keep the ball pumped up, it inevitably deflates: community’s require infusions of capital to stay resilient – or to become more resilient.
