Funny how they can find archeological evidence of agriculture during Muhammads lifetime in Petra, but zilch, zero, nada in Mecca..
An agricultural suburb and other finds unearthed at Petra by archaeologists from the Brown University Petra Archaeological Project suggest that extensive terrace farming and dam construction in the ancient desert city began some 2,000 years ago, not during the Iron Age as had been previously hypothesized.The successful terrace farming of wheat, grapes and possibly olives, resulted in a vast, green, agricultural ‘suburb’ to Petra in an otherwise inhospitable, arid landscape.
This terrace farming remained extensive and robust through the third century. Based on surface finds and comparative data collected by other researchers in the area, however, it is clear that this type of farming continued to some extent for many centuries, until the end of the first millennium (between AD 800 and 1000). That ancient Petra was under extensive cultivation is a testament to past strategies of land management, and is all the more striking in light of the area’s dry and dusty environment today.http://www.sci-news.com/archaeology/article00804.html
