Urban Farm DB summary
This study measured nocturnal air temperatures in 13 allotment garden complexes (AGCs) during the summer of 2018 in Berlin, Germany, comparing them to measurements in densely built-up urban areas, two large inner-city parks, and rural areas. On average, the assessed AGCs were 2.7 K cooler at night than urban areas, and most investigated AGCs (11/13) showed a larger mean nocturnal air temperature difference than urban parks. The nocturnal air temperature difference decreased significantly as the floor space index around AGCs increased, and shape complexity showed a significant positive correlation, while AGC size and distance to the city center significantly decreased with increasing nocturnal air temperature difference.
