Terracing

Terracing is a form of Technology and Culture.

Description
It's difficult to farm hillsides with cereal crops, as water runs off. Converting the slopes to a series of stepped terraces provides flat lands for cultivation, and allows water to be retained. Generally some method of pumping water up the hillside to the terraces will also be required.
