Archaeologists trace early irrigation farming in ancient Yemen

Washington, July 17 (ANI): A team of archaeologists has discovered new evidence of ancient transitions from hunting and herding to irrigation agriculture 5,200 years ago in Yemen.

As part of a larger program of archaeological research, Michael Harrower from the University of Toronto and The Roots of Agriculture in Southern Arabia (RASA) team explored the Wadi Sana watershed documenting 174 ancient irrigation structures, modeled topography and hydrology, and interviewed contemporary camel and goat herders and irrigation farmers.

"Agriculture in Yemen appeared relatively late in comparison with other areas of the Middle East, where farming first developed near the end of the last ice age about 12,000 years ago," said author Michael Harrower, Department of Anthropology, University of Toronto.

"It's clear early farmers in Yemen faced unique environmental and social opportunities and challenges. Our findings show farming in southern Yemen required runoff diversion technologies that were adapted to harness monsoon (summer) runoff from the rugged terrain along with new understandings of social landscapes and rights to scarce water resources," he added.

The researchers used computer Geographic Information Systems (GIS) mapping to determine that ancient forager-herders developed expert knowledge of hydrology and targeted particular small watersheds and landforms for irrigation.

Studies of contemporary land and water rights, including principles enshrined in Islamic law, suggest their origins lie at the very beginnings of water management as tribal principles of water equity intertwined with changing ideologies and culture. (ANI)
