Ancient farmers built stone walls that increased crop yields by three hundred percent
Ancient European farmers mastered landscape engineering 7,000 years ago, constructing massive stone terraces that tripled their food production on steep mountain inclines.
As early as 5000 BCE, prehistoric farmers in Switzerland and Italy transformed 50-degree slopes into productive farmland using dry-stone walls. These engineering marvels retained soil depths of up to three meters, boosting crop yields by 300%. These modifications were so effective that many original boundaries still align with modern land records.
