Bridging versus Bonding Social Capital in Community Resilience
Quick fact
Communities with high bonding social capital (strong ties within a group) but low bridging social capital (weak ties to outside groups) can become 'bonded but isolated', which paradoxically makes them more vulnerable to large-scale disasters than communities with a balanced mix of both.
Why this is interesting
Ever wondered why some tightly-knit communities fall apart after a disaster, while others with looser connections bounce back faster? The answer may lie in the different kinds of 'glue' holding them together.

Understanding Bridging versus Bonding Social Capital in Community Resilience
Think of social capital as the connections between people that enable them to work together. When a flood hits, your neighbor helping you move furniture is bonding social capital - it's the strong, trusting ties you have with people like you, often family, close friends, or people in your same neighborhood or ethnic group. This kind of capital is fantastic for emotional support and quick, small-scale help. But when you need a loan to rebuild your house, need a specialist to fix your well, or need to coordinate with emergency services, you likely don't have that connection through a close friend. You need bridging social capital - the weaker, more casual ties to people outside your immediate circle, like a friend of a friend who works at a bank, a volunteer from a different town, or a member of your religious congregation's sister church. These bridges are like overpasses connecting your island to a highway system, giving you access to resources and information that don't exist on your island alone. A resilient community needs a healthy mix of both: the strong glue of bonding to hold its members together, and the wide bridges of bridging to connect it to the larger world.
A deeper explanation
The mechanism behind why bonding and bridging matter differently lies in what each type provides and what it fails to provide. Bonding capital creates high trust and strong social norms, which makes in-group cooperation fast and reliable. But it often comes with a 'dark side': it can foster distrust of outsiders and create closed networks that hoard resources and information. These dense, homogenous networks are great for surviving a small, localized crisis that is entirely within the group's capacity to handle. However, for a big disaster, the resources held within the group are often insufficient. Bridging capital, by contrast, acts as a conduit for new information, novel ideas, and external resources. It leverages 'weak ties' that connect your group's network to other networks, opening access to a vastly larger pool of potential help. This is why communities that rely only on bonding can become parochial, trusting only their immediate circle and neglecting the outsiders who might offer unique assistance, ultimately trapping them in isolation. Resilience, then, is not about having more social capital; it is about having the right balance. A community with high bridging capital but low bonding can be fragmented and lack the internal cohesion to act collectively. The most resilient communities pair the solidarity of bonding capital to mobilize and act together with the connectivity of bridging capital to bring in outside support and expertise.
