Vallerani System

The Vallerani System combines the traditional techniques of rainwater harvesting and mechanization for large scale land restoration.

The speed and the scale of the intervention can boost a shift of the whole ecosystem
The Vallerani System is based on 3 main aspects and each project is a creative and unique combination:

The social approach is based on a long-lasting collaboration between all stakeholders, the participatory approach and the active involvement of the local population
The technology: the special plough Delfino 3s goes in and out of the soil digging micro-basins for water harvesting and for the collection of fine soil and organic matter
Agronomic and forestal practices such as direct sowing of local species, agroforestry and sylvo-pastoral techniques
The technology

The special plow Delfino 3s has been conceived by Venanzio Vallerani in close collaboration with the technicians of the Italian manufacturer Nardi Group to mechanize the traditional techniques of water harvesting.
