飓风吹倒了夏威夷的牛油果树，一个小岛用掉在地上的果子办了场比赛，救下了自己的电台

This September, Hurricane Lowell made landfall in Hawaii, and the island worst hit was Kauaʻi.

The damage it caused was the conventional kind: widespread power cuts, roads severed, houses damaged, state parks closed indefinitely.

But this hurricane also left behind something highly unconventional.

After the wind dropped, people pushed open their doors to find the ground covered in fallen trees.

A large share of them were avocado trees.

The timing was bad in a way that felt almost deliberate.

Hawaii's avocado season happens to begin in September.

Which is to say, these trees were torn up by the roots at the exact moment they were carrying the most fruit.

Overnight, thousands of avocados appeared on the ground.

To understand what happened next, you first need to know one thing about Hawaii's avocados.

There are around two hundred different varieties here, ripening at staggered times, and differing in size, oil content and flavour.

Variety on that scale meant it could never become a standard commodity that can be bought in bulk and shipped out.

For a long time, Hawaii's avocados have moved in only one way: neighbours giving them to each other.

Now this thing that already travelled on goodwill suddenly exceeded what anyone could handle.

Left out it rots, and throwing it away comes close to wasting food — and the aftermath of a disaster is exactly when food should least be wasted.

So the island produced a scene that was photographed over and over and posted online.

At the roadside, in shop doorways, beside petrol stations, outside people's own yards, one container after another was set out.

Buckets, cardboard boxes, wheelbarrows, canvas bags — every one of them full of avocados.

The wording varied slightly, but it all meant one thing: free, help yourself.

Something said by a local woman who works in food describes the mood precisely.

She said nearly every community was piled with bins of free avocados, so it looked like a good opportunity.

The opportunity she meant pointed at something more pressing happening on the island that same week.

Kauaʻi has a community radio station.

During the hurricane, with widespread outages and no phone signal, a radio is often the only thing still working.

What the station broadcasts is the most concrete material there is: which roads are open again, whether the tap water is drinkable, where to collect food.

In other words, it is part of the post-disaster infrastructure — it just happens to be the part the government does not run.

Yet on the ninth of September, the station itself put out an appeal.

It said its diesel was nearly gone and the generator would not hold out much longer.

Once the diesel ran out, the station would have to stop broadcasting.

This produced a very sharp situation.

One hurricane simultaneously made everyone desperate for information and came close to silencing the only people still able to supply it.

The solution came from that pile of unwanted fruit.

The thing the island has least shortage of right now is avocados — so use avocados to buy the fuel the station needs.

On the afternoon of the seventeenth, a guacamole contest was held behind a small restaurant in Old Kapaʻa Town.

Twenty-five batches of guacamole were entered, every one of them made by local people.

The organisers had estimated that a hundred people turning up would count as a success.

Close to two hundred came.

Their fundraising target was two thousand five hundred dollars.

What they took in was over five thousand — twice the target.

The station did not go off the air.

Lay the whole chain out end to end and its shape becomes very clear.

The hurricane overturned the trees, the trees shook loose the fruit, the fruit was exchanged for money, the money bought the diesel, and the diesel let the station go on telling people what to do after a hurricane.

What was destroyed became the material that repaired it.

This is worth telling because it states a fact that is usually overlooked.

What actually works in disaster recovery is often just whatever a community happens to have left in its hands, plus whether anyone thinks of a use for it.

Big plans take time. The avocados were already on the ground.

If one day a box of unclaimed fruit turned up outside your door, would you carry it home, or walk past as though you had not seen it?
