I came up with this idea while leading a discussion in Bonn about "breakthrough" ways to help people in developing countries who are facing facing food and water problems.

After hearing a number of~~weak~~ hopeful suggestions, I set a few ground rules:

I have two answers to these problems. The small-scale solution is to make it easier for outsiders to understand the scale of the problem -- and the scale of the reward awaiting its solution. (I'll blog on the large-scale solution tomorrow.)

I suggest that each "block" of houses conduct a daily or weekly survey of how much time/money each household spent on gathering and preparing water for consumption. Those statistics could be posted on the corner of the block. That sign would make it easier for residents to understand the scale of the problem they all face, easier for entrepreneurs to understand the rewards awaiting their solutions, and easier for politicians and regulators to understand the scale of water managers' failure to provide good service to citizens.

Such a blackboard on the corner -- a device that allows any message to be broadcast -- could be used for a number of local community problems.

- You cannot solve problems with lots of money, e.g, vertical farms or build a first world sewer system.
- You cannot assume cultural evolution, e.g., "act like the Dutch."

**Bottom Line:**We need to know the scale of the problem before we can make an appropriate response -- and sometimes "we" need help.
