Leran appears to be in the Market gardening zone; fruits, vegetables, flowers. I can tell you I saw lots of grazing land and sunflowers seemed to be the major crop. Over near Chalabre there were apple orchards and just over the hills and down towards Limoux, you passed into a wine-growing region. France is definitely blessed with a region for growing or harvesting almost anything. Seacoasts for seafood, plenty of room to raise beef and dairy cattle, forests for lumber, mountain pastures for sheep and goats and the resulting cheeses, plains for cereal crops, olive trees for olives and oil, and of course vineyards for wine. France is about twice the size of Colorado but has a place to grow almost all major crops except rice.
