Urban agriculture in historic cities

The integration of urban agriculture into historic buildings and towns represents a forward-thinking approach to climate change mitigation and adaptation. Urban farming contributes to carbon sequestration and greenhouse gas reduction while enhancing air quality through pollutant filtration and oxygen release. Green spaces play a crucial role in counteracting the urban heat island effect by decreasing heat absorption and providing shade. Additionally, they improve stormwater management by facilitating rainfall absorption, mitigating flood risks, and reducing runoff contamination. The introduction of vegetation within urban environments further promotes biodiversity by creating new habitats for plant and animal species. Despite these advantages, the implementation of UA in heritage contexts presents several challenges. Land use conflicts may arise, particularly in dense urban areas where preservation priorities and development interests compete for space. Water management poses another critical issue, as historic buildings were not designed to support extensive irrigation systems. Structural adaptations required for urban farming, such as greenhouses or rooftop gardens, may necessitate reinforcements that could impact the integrity of historic structures. Furthermore, modifications to building materials and surfaces to accommodate plant growth must be carefully managed to prevent adverse esthetic and conservation impacts. This study explores a range of urban agriculture techniques, assessing their feasibility within heritage contexts and historic cities.
