When we cannot protect everything equally, who should decide what gets protected first?
Climate adaptation is already happening. The harder question is how we decide where to adapt first, and who gets to make that decision.
The World Bank estimates that making infrastructure more resilient in low- and middle-income countries can produce about four dollars in benefits for every dollar invested. Prevention can pay, but resources are finite. That makes prioritization unavoidable.
Expected losses avoided per dollar spent might help decide where investment does the most good. But a spreadsheet cannot tell us what a historic community is worth, whether a poorer neighborhood should receive less protection than an expensive waterfront, or what is lost when people have to leave a place they've called home for generations.
There's also the question of who gets a voice. Governments allocate public investment, insurers increasingly price risk, property markets respond, and communities themselves live with whatever is decided.
As risks increase, insurance can become unaffordable and investment can move elsewhere. A place doesn't have to disappear to become difficult to inhabit. It can become economically uninhabitable first.
The hazard may be shared.
The ability to escape it isn't.
These choices will be made one way or another, deliberately or by default. Who decides, and what guides that decision, may end up mattering as much as how much money is spent.
