Abstract

In response to the growth of urban population and the reduction of resources availability (e.g., arable land, water, and nutrients), new forms of agriculture that can be developed also in urban environment are gaining increasing popularity. Urban agriculture constitutes a viable opportunity for improving the city food security, also fostering local and circular economies, social inclusion, and environmental sustainability. In the different world regions, a diversity of urban farming systems is encountered, with technological levels varying in response to the local socio-economic context, infrastructural networks, and environmental conditions. In developing economies from the South of the world, most interesting innovations include simplified hydroponics, organoponics, and microgarden technologies; whereas, in the global north, innovative solutions for plant cultivation also include rooftop greenhouses and indoor vertical farms with artificial lighting where vegetable crops, mushrooms, and algae may be grown. Beside plant growing solutions, innovation may also stand in the system integration and mutual relationship with the urban fabric (e.g., in terms of resource use or ecosystem service provisioning), or in the business model adopted. The present review paper will describe a number of innovative solutions for plant cultivation in the urban environment, with a special consideration of the economic, environmental, and social sustainability.

49. Green spaces in Italy from subsistence agriculture to public parks: the city of Bologna from 13th to 20th century

Abstract

As many other European cities, Bologna has wide green spaces inside the city walls, especially in the Middle Ages, when the role of subsistence agriculture is really important; during the Renaissance, this scenario partially changes; and in the Modern Era the importance of gardens and public parks is growing. After Italian unification (1861), urban development enters into dialectical relationship with the protection of public green; new public gardens are built within the historic city and a large public park is inaugurated immediately outside the Renaissance walls. These events prelude to the urban development of Bologna outside its historical borders, according to a process that unites Bologna with several other cities of central and northern Italy, although with some differences with regard to policies for the protection of public green during the 20th century.

Abstract

Intercropping and rotation systems involving legumes can be useful means to achieve a sustainable agricultural production. Biological nitrogen fixation (BNF) is widespread among leguminous species thanks to their ability to establish symbiosis with nitrogen (N) fixing microorganisms. Moreover, the application of intercropped legumes increases the agricultural biodiversity and helps farmers to reduce N leaching preventing soil erosion and weed spreading. Little information is available regarding the contribution of N2 (atmospheric nitrogen) from symbiotic fixation of pea and clover when involved in intercropping or in succession systems with other vegetable crops. This study, carried out in a mountain agroecosystem (Venosta Valley, South Tyrol, Italy), has been conceived as part of a more complex research trial on N optimization of cauliflower intercropped and in succession with other vegetables. We have applied the 15N natural abundance technique to field grown clover and dwarf pea, with or without external N supplied, to assess the potential contribution of N2 for intercropping and crop rotation. The technique exploits naturally occurring differences in 15N abundance between plant available N sources in the soil (more enriched in the 15N isotope) and that of N2 in the atmosphere (δ15N=0‰). When a legume crop fixes N2, its 15N abundance should be lower than that of a no-N fixing crop, exploiting only the soil N pool. Reference plant N derived from atmosphere (%Ndfa) was the white cauliflower (Brassica oleracea var. botrytis), one of the most important vegetables on a world scale belonging to the Brassicaceae family and the first vegetable crop cultivated for fresh consumption in South Tyrol. In our study, clover and pea crop residues contained around 74 and 43 kg N ha‑1, respectively. The %Ndfa for the two legumes was similar and ranged from 20% (dwarf pea) to 22% (clover). In presence of external N fertilizers, values of δ15N of the species resulted lower in comparison with the unfertilized control, making the BNF estimation difficult. The study indicated clover and dwarf pea as a potential tool to reduce inorganic fertilizers supply when included in a rotation system. Further trials are needed to confirm our results on BNF of the analysed species in different agroecosystems.
