The Project

This publication has been produced as part of the

Miglioramento e valorizzazione della palma da dattero nelle

Oasi di Al Jufrah in Libia program for improving and

promoting date palms in the oases of Al Jufrah in Libya,

funded by the Directorate General for Development

Cooperation of the Italian Ministry for Foreign Affairs and

coordinated by the Istituto Agronomico per l'Oltremare

(IAO) in Florence in collaboration with the Libyan Board of

Improving and Developing Olive and Palm Trees.

The project’s origins lie in the commitments made between Italy and Libya to strengthen and

develop relationships between the two countries. The central government and local authorities

in Libya share an interest in improving agricultural, forestry and pastoral systems. As part of the

effort to support the agricultural improvement of land cleared of Second World War surplus, the

Italian government has begun providing assistance and collaboration in the agro-zootechnical

and environmental sector.

In Al Jufrah, activities agreed on by the two countries began in May 2009. They are aimed at

encouraging local economic development through coordinated actions to support producers of

quality dates, whether individuals or associations. The strategy is led by two guiding principles:

identifying and guaranteeing quality dates through production protocols that will ensure the

consistency and quality of the final product; and protecting the agrobiodiversity of Al Jufrah by

promoting the local palm varieties and strengthening traditional oasis-management systems.

The initiative involves all the actors in the date production chain, reinforcing associations and

relationships between producers, processors and traders; encouraging the protection of the

environment and raising awareness about quality dates among consumers. This last objective

will draw on experiences in Italy promoting typical local products using the Protected

Designation of Origin (PDO) and Protected Geographical Indication (PGI) systems, closely linking

a product and its place of origin.

The aims of the Italo-Libyan technical and

scientific collaboration are to increase the

quantity and quality of date production

through the selection and genetic

improvement of local varieties; to introduce

cultivation systems able to optimize the use

of water and energy resources and reduce

negative external effects; and to improve

processing systems and marketing

domestically and abroad.
