Soils are archives of the past

Reminders from ancient civilisations

Many civilizations were built on fertile soils, and history shows that when soils were degraded faster than they could recover, societies often became more vulnerable to crisis. Throughout history, soils have conditioned human societies by influencing where people settled, how food was produced, and which regions could support growing populations. In turn, humans have continuously shaped soils through activities such as farming, irrigation, deforestation, construction, and waste deposition. People often settled in fertile river valleys and floodplains, where regular flooding deposited fresh sediments and nutrients that helped maintain productive agricultural land. Soil therefore not only reflects natural processes but also stores evidence of how humans have managed and transformed landscapes over long periods of time.
