The Bronze Age (2200 to 800 BC) marked a decisive step in the technological and economic development of ancient societies. People living at the time faced a series of challenges: changes in the climate, the opening up of trade and a degree of population growth. How did they respond to changes in their diet, especially in Western Switzerland? A team from the University of Geneva (UNIGE), Switzerland, and Pompeu Fabra University (UPF) in Spain has for the first time carried out isotopic analyses on human and animal skeletons together with plant remains. 

The scientists discovered that manure use had become widespread over time to improve crop harvests in response to demographic growth. The researchers also found that there had been a radical change in dietary habits following the introduction of new cereals, such as millet. In fact, the spread of millet reflected the need to embrace new crops following the drought that ravaged Europe during this period. Finally, the team showed that the resources consumed were mainly terrestrial. The research results are published in the journal PLOS ONE.
