Massire: Strengthening agricultural and rural innovation systems in oasis and arid zones
In Algeria, the Massire project (“Ma” for Maghreb, “ssi” for innovation system, and “re” for water resources) concerns the wilaya of Ghardaïa, at the gateway to the Sahara. Water resources, which are mainly underground due to the very low rainfall, are mainly fed by floods caused by the flooding of wadis following downpours on the…
