So 40% of the world's population live near the coast.

So we've got sea level rise, intense storms, and by some estimates, half a billion to a billion people will be adversely affected by what's going to happen on the coast.

But that's not the only problem.

it's a bit more complicated than that.

It's not just storms are increasing, sea level rise is going to flood these areas.

You have secondary issues such as acidification that's going to damage coral reefs and natural systems.

You have changing wind patterns because ocean temperatures are increasing and storms are getting more intense and also more unpredictable.

And on top of that, you've got increased rainfall

and flooding that is happening deeper in the coast, in coastal communities.

This is a big problem.

And it's a personal problem for me as well.

I'm from Singapore, an island state in Southeast Asia, many coastal communities.

I worry about what's going to happen to my region, how it's going to impact my family.

I've got three boys that have grown up along the coast.

And with that, I've spent the last two years helping countries and coastal communities build resilience against climate change.

What's the challenge?

The challenge is no two coasts are alike.

They're highly diverse, physically diverse,

They have different distributions of populations, and they're socio-economically different in terms of the communities that live there.

Now, there are many solutions to protect the coast.
