This study used spatial overlay analysis of global cropland and urban extent data to estimate the global area of urban and peri-urban irrigated and rainfed croplands. Urban irrigated croplands were estimated at approximately 24 Mha (11.0% of all irrigated croplands) with a cropping intensity of 1.48. Urban rainfed croplands were estimated at about 44 Mha (4.7% of all rainfed croplands) with a cropping intensity of 1.03. Additionally, 60% of all irrigated croplands and 35% of all rainfed croplands were found within 20 km of urban extents.

Urban agriculture in developing countries is a vital asset in the livelihood strategies of urban households, having expanded rapidly over the last two decades and contributing to income generation for unqualified workforces. However, the illegal status of urban agriculture has created a governance vacuum, necessitating policy formulation and institutionalized management to secure land for the urban poor and improve food security and the environment. Political leaders have a role in regulating this sector.

This study, conducted from January to December 2013 in three major vegetable farms in southern and northern Benin, assessed the genesis and rapid expansion of urban agriculture. It found that while Christian missionaries initiated early vegetable farming, its current growth is driven by urban unemployment, rural exodus, and the search for balanced diets, increasing farmers' household income. The activity is dominated by young people (21-40 years old), with 75% being permanent gardeners, but farmers improperly used various pesticides, leading to insecticide resistance in malaria vectors.

This study developed a theoretical model to capture, quantify, and interrelate the most relevant variables and constraints of potential food production in domestic gardens. The model development was fostered by quantitative and qualitative data collection for the Flanders case study, providing insights into current and potential food production in Flemish domestic gardens. While not finalized, the model allows exploration of spatial and temporal constraints of individual domestic gardens for food production, contributing to a better understanding of the adaptive capacity of small-scale multifunctional spaces.

Roberta Pucci · · Italy (Settimo Torinese)

A project for urban transformation in the HT6 Bordina area of Settimo Torinese, Italy, was proposed. This project critiques a previous plan for 15-story buildings as invasive for the surrounding low-rise residential area and presents a more sustainable alternative, including social and production spaces like an urban garden, playground, and commercial square. The proposal aims to connect existing green areas, residential areas, and a historic farmhouse.

This lecture focuses on five geographical questions concerning the rural-urban interface. It was shown that major food industries are not necessarily located in main cities, leading to a frequent disconnection between agricultural and regional centralities, and that the disconnection between cities and agricultural surroundings is challenged by farmers through short food supply chains. Access to the countryside by city dwellers is a major issue for social interaction, and urban agriculture opens new opportunities for urban planning.

The supply chain supporting urban food consumption currently stresses the environment at planetary, regional, and local scales. Urban agriculture (UA) is claimed to mitigate environmental burdens from urban food needs, but the veracity of these claims remains inconclusive. This study addressed the lack of meaningful systematics by developing a system that categorizes UA into five broad types, optimized for comparing environmental performance.

The Polish National General Exhibition in Poznań in 1929 attracted many laborers, who later contributed to the unemployed population during the 1930s economic crisis, exacerbating the housing crisis in Poznań. City authorities initially housed the homeless in former exhibition grounds as an interim measure. For a more permanent solution, the city redeveloped allotments or community gardens by building purpose-built residential garden huts or sheds.

This article examines permaculture design, developed by Bill Mollison and David Holmgren, not only as an application of systems theory but also as a form of figurative, ecological reasoning. Permaculture challenges the division between theory and practice, or rationality and sensibility, inextricably linking these modes of knowledge in explorations of patterns. Specifically, it describes permaculture design thought through three aspects: visual thinking in patterns, the role of radical imagination and speculation, and systems theory thought drawing from the Gaia hypothesis.

Rapid urbanization has led to negative consequences such as urban poor, primarily formed in suburbs. The physical expansion of cities occurs more in suburbs, causing "urban sprawl" into rural areas beyond their boundaries, resulting in the loss of agricultural lands and stress on the surrounding natural environment.

This paper traces the history of kitchen gardens and their relationship to urban food provisioning, examining how domestic fruit and vegetable production was influenced by commercial production, new distribution methods, and kitchen technology. It discusses how, around 1900, kitchen gardens were viewed as solutions for food scarcity and urban moral hazards, and how gardening evolved from a necessity to a pastime. The paper also notes a recent revival of interest in home food production, highlighting its renewed moral significance in response to the modern food system.

This study sampled two plant-herbivore-parasitoid systems across 250 sites in a 360 km2 urban/agricultural landscape to investigate the impact of human development on trophic interactions. It found that herbivorous insect densities were decoupled from host tree densities in urban landcover types at several spatial scales. Furthermore, a parasitoid species was absent from all urban/suburban landcover in one system, even where its herbivore host was common, indicating that human land use patterns limit specialist insect distributions due to dispersal constraints.

de Vries, Arianna · · United States (New Jersey)

This study investigated three large-format suburban community gardens, each with over one hundred plots, in Central New Jersey, United States. Using geospatial mapping, on-site observation, and interviews with coordinators and gardeners, the research explored participation reasons and the suburban conditions fostering these gardens. It found that suburban gardeners participate for reasons similar to their urban counterparts, but the suburban context significantly shapes how these motivations are defined and described.
