In my part of the world we have water restrictions in place. The current restrictions allow people to water their garden twice a week: between the hours of 6am-8am and 8pm -10pm.
We all agree it makes sense to water in the cooler hours of the days.
We have now entered the next phase of restrictions. Which only allow us to water the garden once on selected days. If we had decide whether the watering be allowed in the morning or night, we’d all say – at night. Common sense says that there is less evaporation through the night – a more efficient use of water.
The decision was made to only allow watering in the morning. The water authority knows less water will be used. Why? We have to get up early. They know we won’t do it as often. Though it is less efficient, we save more water.
Strategy must be based on behaviour, not rationale.
