I am at the University of Washington in Seattle discussing grand challenges in tech policy. When asked to identify a grand challenge in the tech policy space that was uniquely relevant in my own country, I proposed action to minimize impact on livelihoods as described in the piece I wrote after the April Kelani river flood: As I read general alerts of the type quoted above, I wonder how a person could react. So for example, what do I do, as a resident of Kegalla District, when I am told there is a risk of landslides in the District? For specific action, I would need a specific warning, such as “there is a 75 percent probability of this particular hill looming over my house sliding down if there is more than one hour of continuous rain.” I would need to know where to go.
