The continuous population growth and built-up areas expansion requires an increasing urban demand for goods and services and a high pressure on land resources. As a result, farming adaptation around cities in a multifunctional way is a must in their effort to reach resilience, sustainability and food security. In Romania, agriculture in metropolitan areas is still dominated by small family households owned by undertrained aged people, practicing subsistence agriculture, most of them with little financial resources. Thus, the paper aims to identify and analyze the ways multi-functionality can contribute to sustainable farming by addressing some of the key sustainability solutions in southern Romania (i.e. Bucharest Metropolitan Area) – a region characterized by extended and fertile agricultural land resources, significantly transformed during the post-communist period through land abandonment and fragmentation, but also by land concentration and grabbing to the detriment of traditional farming. By combining quantitative (spatial and statistical analyses) and qualitative (questionnaires & interviews to key actors) approaches, the authors pinpointed critical issues of metropolitan farming (e.g. type of agricultural activities, agro-support services, urban pressures, market access, networking, survival strategies) to support sustainability.
