Historical Context of Urban Farming

As we explore the historical context of urban farming, we’ll uncover how it transformed from necessity to a movement seeking to reshape city landscapes. Urban agriculture has played a critical role in the past, serving as both a response to urbanization and a bridge back to rural traditions.

Transition From Rural to Urban Settings

Urbanisation significantly altered land use, especially during the Industrial Revolution, as many people moved to cities for employment. This shift not only led to crowded urban centres but also the emergence of “food deserts,” areas with limited access to fresh, healthy, and affordable food. Against this backdrop, the utilisation of limited urban space became innovative, as vacant lots and rooftops turned into productive gardens. Urban farming became a solution for fresh produce and mitigating some of the negative impacts of dense urban living.

Urban Farming in the 20th Century

By the 20th century, urban agriculture became a vital part of many cities, particularly during times of economic hardship or war. Post-World War II, cities worldwide saw a decline in urban farming as industrialisation took precedence and land use policy favoured commercial over agricultural use. However, the latter part of the century witnessed a revival, buoyed by growing environmental consciousness and community initiatives to reclaim abandoned spaces. This renaissance of urban farming sprouted community gardens and local food production, drastically transforming parts of cities into vibrant, green, food-producing areas.

Modern Urban Farming Movements

Urban farming movements are revitalising cities across the globe, utilising innovative techniques to grow food and bringing greenery back into the urban landscape. From vertical gardens to community plots, these projects not only provide fresh produce but also foster community spirit and environmental awareness.
