“…In the recent years, however, UA has become an increasingly relevant topic in the science and planning of urban food systems aimed at reducing food insecurity at the level of the household (Kortright and Wakefield 2011;Smith et al 2013) and community (Howe 2002;Kremer and DeLiberty 2011;Besthorn 2013). While the contribution of UA to a resilient local food system is highly valued, the subject of UA itself remains vague.…”

Contributing to food security in urban areas: differences between urban agriculture and peri-urban agriculture in the Global North

Food security is becoming an increasingly relevant topic in the Global North, especially in urban areas. Because such areas do not always have good access to nutritionally adequate food, the question of how to supply them is an urgent priority in order to maintain a healthy population. Urban and peri-urban agriculture, as sources of local fresh food, could play an important role. Whereas some scholars do not differentiate between peri-urban and urban agriculture, seeing them as a single entity, our hypothesis is that they are distinct, and that this has important consequences for food security and other issues. This has knock-on effects for food system planning and has not yet been appropriately analysed. The objectives of this study are to provide a systematic understanding of urban and peri-urban agriculture in the Global North, showing their similarities and differences, and to analyse their impact on urban food security. To this end, an extensive literature review was conducted, resulting in the identification and comparison of their spatial, ecological and socio-economic characteristics. The findings are discussed in terms of their impact on food security in relation to the four levels of the food system: food production, processing, distribution and consumption. The results show that urban and peri-urban agriculture in the Global North indeed differ in most of their characteristics and consequently also in their ability to meet the food needs of urban inhabitants. While urban agriculture still meets food needs mainly at the household level, peri-urban agriculture can provide larger quantities and has broader distribution pathways, giving it a separate status in terms of food security. Nevertheless, both possess (unused) potential, making them valuable for urban food planning, and both face similar threats regarding urbanisation pressures, necessitating adequate planning measures.

“…Using geospatial and/or statistical methods, some researchers have analyzed the impacts of UA and urban greening programs on neighborhood property values (Been & Voicu, 2006), quality of life (Tranel & Handlin, 2006), and crime (Kuo & Sullivan, 2001). Other relevant quantitative studies have discussed community food access and spatial inequality (Hallett & McDermott, 2011;Hubley, 2011;Raja, Ma, & Yadav, 2008;Russell & Heidkamp, 2011;Smoyer-Tomic et al, 2008) and the potential and capacity of urban food production (Kremer & DeLiberty, 2011;Metcalf & Widener, 2011). On the other hand, many researchers have studied community gardening as a social process by using qualitative methods (Teig, Amulya, Bardwell, Buchenau, Marshall, & Litt, 2009).…”

“…Modelling water use in UA and identifying alternative water sources are pivotal components for resource-conscious urban planning and design, a context where both social and ecological process driving resource flows at different spatial and temporal scales have to be thoroughly understood [75]. In this context, resorting to geospatial information from different sources and image-based processing techniques (i.e., feature extraction by photointerpretation and semi-automatic imagery classification) are stepping stones for collecting information on land use/cover and resources at fine spatial resolution to investigate urban food production [49,[76][77][78].…”

Exploring Rooftop Rainwater Harvesting Potential for Food Production in Urban Areas

et al. 2017

Homegrown fruits and vegetables are gaining popularity in many metropolitan areas with several facets connected to the wider urban agriculture phenomenon. At the same time, the relationship between urban food production and irrigation water is pivotal in terms of resource management. In this paper, we investigated water savings through the collection and use of harvestable rainwater from buildings' rooftops to irrigate 2631 fruits and vegetables gardens in the urban area of Rome (Italy). The methodology makes use of existing geospatial data and data derived from satellite image classification to estimate food gardens' irrigation requirements and harvestable rainwater from nearby buildings' rooftops. The comparison of the annual harvestable rainwater with irrigation needs allowed for computing the proportion of water self-sufficient gardens as well as the amount of gardens whose water needs might be partially fulfilled with rainwater. Statistics were produced by land use type (horticulture, mixed crops, olive groves, orchards, and vineyards) and under the hypothesis that irrigation systems with low and high field application efficiency might be employed. We found that 19% and 33% of the gardens could be water self-sufficient for the low and high irrigation efficiency scenario, respectively. The remaining gardens, by using the available rainwater, could satisfy 22% (low efficiency) and 44% (high efficiency) of the water needs resulting in a reduction in the use of conventional water sources.
