Ever observe the farming practices of the followers of Islam? For centuries the people living on land that was useless sold it to Israelis after the Balfour decision. In twenty years the Israelis turned it into highly productive agricultural land. They applied modern agricultural methods of farming, ran irrigation lines, electricity, access roads, crop storage facilities, and developed markets for the produce. It was now that arabs who sold the land demanded it back! After selling it and finding out what it could have been for 600 years and did nothing with it, now they want it back?
Typical Arab mentality. Scratch the dirt with a stick to farm and steal what you can't produce for yourself.
European agriculture advanced when they could do irrigation, out from behind a wall -those walls, those castles, were built to resist the Muslim slave trading hoard.
