Early Neolithic agriculture in the Iberian Peninsula

The spread of agriculture in the Iberian Peninsula is documented from at least ca. 5600-5500 BC, although botanical data are absent or very limited for large areas. Archaeobotanical information shows from the beginning an imported agrarian system with a great diversity of crops: hulled and naked wheats and barleys, legumes such as pea, lentil, lava bean, vetches and grass peas, flax and poppy. This diversity of plants with different requirements, processing and uses, implies that the first farmers quickly imported or acquired a wide range of agrarian knowledge. Regional and inter-site agrarian differences are discussed in relation to factors like ecology, culture, use of the cultivated plants and management of the risk of crop failure. The adoption of farming resulted in significant ecological, economic, dietary, and social changes,for the Neolithic people of Iberia.
