terracing system for the protection and cultivation of the slope.
The water intakes deviate the flows from their natural course and
direct them along the walls on the terraces. Towers and stone buildings
are placed to defend the cultivations. |

The
hydro-agricultural origin is important to understand the urban
layout of the Sassi of Matera. Above, the Sasso Barisano is a
basin into which water coming down from the plain above conveyed.
Below, an overhanging garden resulting from the threshing-floors,
the agropastoral matrix on which the process of urbanisation was
implanted.

by terraced fields. |

| 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.

| Restoration
of the hanging gardens and the terraced steps of the gravina of
Laterza (Laureano, 1999). The traditional practice of hanging cultivations
is confirmed by the restoration and amplified by the organisation
of terraced slopes used in the phytodepuration system. |

| A
proposal for rebuilding the water system and the tilled terraces
of wadi al-Mataha (Petra). The restoration of the ecosystem and
the revival of the vegetation are not only a new archaeological
attraction managed by the bedu groups, but also the defence of the
environment against the erosion and demolition of the sandstone
walls. |
