by means of dry stone walls. |

On the left, at the bottom of the marbid the stone walls which
organize the terraced slope and collect humidity. On the right,
the stone walls and dams called harrah which share out the water
quotas.

a large system of organization of valleys by means of water devices.
Along the natural water course the dams called masraf intercept
the flows running down the steepest slope and deviate them towards
the cultivated terraces on both sides. |
|
| Massive
dry stone walls protect from the effects of the rainfalls and create
the space for cultivations organised on artificial terraces along
the slopes of the Palomba of Matera. |

| Ibiza
(Spain), terraced fields called tanka. |
|
| Sion
(Valais), landscape created by the bisse technique, with terraced
slopes where high quality grapevines are grown thanks to an irrigation
system carried out by means of hydraulic devices. The outlet of
the latter determines the location of the historical settlements.
|
|
| Santo
Stefano Belbo (Langhe - Piedmont). Hillsides organized and protected
by terraced fields. |
| Cortemilia
(Langhe). Particular types of terracing systems made out of a series
of stone arches. The arcade enables to save building material and
create some openings useful to the water drainage and catchment.

Mounds
of stones in the shape of a crescent, circles and rows of stones,
found during archaeological excavations in the Hedomite and Nabatean
hydroagriculture, common in all arid and Mediterranean areas for
plant preservation.
