Abstract
The development of agricultural societies is closely entangled with that of domestic animals and plants. Local and traditional domestic breeds and varieties are the result of millennia of selec- tion by farmers. DEMETER (2020-2025) is an international pro- ject which is aiming to characterize the changes in animal and plant agrobiodiversity (pigs, sheep, goats, and barley) in relation with environmental and socioeconomic factors in the northwes- tern Mediterranean basin since the beginnings of agriculture. The project is based on a combination of approaches including phe- nomics (through geometric morphometrics), databasing, zooar- chaeology, archaeobotany, climate modeling, paleoproteins (ZooMs) and statistical analyses. Several hundreds of archaeo- logical sites from the South of France and Catalonia will be stu- died, covering the maximum environmental, societal and cultural diversity of context over the course of the last eight millennia.
