Terre de Liens (TDL) is a non-profit organisation working to preserve agricultural lands and support a new generation of farmers. It owns over 250 farms, over 6000 ha, across France. TDL favours the settlement of new entrants practicing organic agriculture on these farms, renting the land through a special type of long-term farm tenancy contracts called “Environmental Rural Leases” (ERLs). These include clauses to promote environmentally friendly agricultural practices. Most often, TDL includes organic practices and the maintenance of existing agroecological infrastructures (hedges, ponds..) in the ERLs. Other clauses may be included in concertation with farmers and in compliance with the law (out of 16 possible clauses pre-defined by law).
