steppes, terraces,
In prehistoric times in the southwestern US and down into Central America (at least), people built "trincheras" on the sides of mountains. These changed the temperature on the mountain to allow for a longer growing season, as well as helping to capture the rain water that washed off of the mountain.

Terraces
Terraces are strips of land cut out of a hillside like stair steps, used to create flat surfaces for farming or gardening on steep slopes. They help prevent erosion by reducing the speed of water runoff and allow for better water retention in the soil.

Stair lifts are commonly installed in garages. Many garages are built below the grade of the house and require steps to access the living area. If the garage is fully enclosed an interior stair lift model can be used. If the garage is open (no doors) an outdoor unit may be more suitable in humid areas of the country.
