Terracing is an ancient technology allowing the farming and building on steep and indented terrain. Farmland terraces consist of terrace platforms and terrace slopes or walls. In rural settings, the measure can reduce erosion and surface runoff by slowing rainwater to a non-erosive velocity. The measure is recommended for farmland with slopes >15°. However, terraces pose a significant impact. The can, therefore, violate the landscape’s ecological mechanisms. For this reason, they should be considered as an ultimate solution for the utilisation of land as farmland or building area and only if other land uses (e.g. afforestation) are impossible.

Fields of action Settlement areas,Farmland
Additionally to flood risk reduction by slowing and storing surface runoff, the measure has medium or high possible benefits for the following biophysical impacts and ecosystem services: Reduce erosion and/or sediment delivery; Aesthetic/cultural value; Filtration of pollutants
