Stable climate and plant domestication linked
Sustainable farming and the introduction of new crops relies on a relatively stable climate, not dramatic conditions attributable to climate change. Basing their argument on evolutionary, ecological, genetic and agronomic considerations, Dr Shahal Abbo, from the Levi Eshkol School of Agriculture at the Hebrew University of Jerusalem, Israel, and colleagues, demonstrate why climate change is not the likely cause of plant domestication in the Near East. Rather, the variety of crops in the Near East was chosen to function within the normal east Mediterranean rainfall pattern, in which good rainy years create enough surplus to sustain farming communities during drought years. In the authors' view, climate change is unlikely to induce major cultural changes. Their thesis is published online in Springer's journal Vegetation History and Archaeobotany...
