This comparative analysis documents the landscape evolution of the Sector Mas Alba area in Barcelona's metropolitan periphery between 2000 and 2015. The visual evidence captures the transition from open agricultural terrain to developed urban infrastructure, illustrating patterns of suburban expansion in the Barcelona region during the early twenty-first century.

The transformation reveals the characteristic elements of peripheral urban development: new road networks, residential construction, and the reconfiguration of the rural landscape into urban parcels. These changes reflect broader regional planning strategies implemented in Catalonia during this period.
