SUMMARY:

Oslo has experienced an increase in the number of urban agriculture (UA) projects and growth in public interest. The study investigated how user groups could carry out UA projects in two apparently unoccupied plots of former farmland: Bredtvet and Gaustad. Soil characteristics, current land use, users’ desires, and the challenges they perceived for the development of UA projects were studied. It seems possible to integrate UA projects in both areas without disturbing current land uses, thereby leading to
the recuperation of the soil resources of the former farmland. UA can have multiple purposes, such as food growing, social integration, community building, and health improvement. Major challenges hindering UA projects result from lack of institutional support and funding.

“It is highly unlikely that urban agriculture will increase incidences of elevated blood Pb for children in urban areas. This is due to the high likelihood that agriculture will improve soils in urban areas, resulting in reduced bioavailability of soil Pb and reduced fugitive dust.”

Excerpt:

Using compost is the single best thing you can do to protect your family from any danger associated with lead in urban soils. Good compost will also guarantee that you will have plenty of vegetables to harvest.

That’s the main finding of a paper appearing this month in the Journal of Environmental Quality. The University of Washington-led study looked at potential risks associated with growing vegetables in urban gardens and determined that the benefits of locally produced vegetables in cities outweigh any risks from gardening in contaminated soils.

emrge

What is the “trend” here? Are we likely to see barns and silos dotting our cityscapes? No, that is hardly the point. What is important—and trending—is the new vision that has urban land as that most precious and flexible of resources. The idea that the end of one productive use of a real estate asset spells the extinction of value and the sunsetting of opportunity is an idea whose time is over.

7. Food Is Getting Bigger and Closer

This may be the ultimate in niche property types: adaptive use with a vengeance (or at least with veggies).

The classic theory of urban places relegates agriculture to the hinterlands, as virtually every kind of vertical construction has superior “highest-and-best-use” characteristics, bringing greater investment returns to land value than growing food. This is absolutely true in most cases. But there are places in more cities than we might imagine where neighborhood land is cheap or older buildings sit idle, and where median incomes are low and the need for fresh food is high. Some are the “hollowed out” areas of Detroit as well as Camden and Newark, New Jersey. But there is a surprisingly significant level of activity in places like Brooklyn, Chicago, Philadelphia, and Washington, D.C., where “foodies” of all generations abound.

Abstract

Based on a qualitative study of Hanoi underprivileged households’ livelihoods, this article addresses the role of urban and periurban agriculture in the food securitization process. It begins by showing that the spatial dynamics occurring in the emerging metropolis induce strong competition for the various uses of land. The urbanization process is based on a tremendous land-seizure policy, and officials seem to regard farmland as a land reserve instead of as a source of food.

First online: 23 October 2015

Abstract

Rooftop gardens, rooftop greenhouses and indoor farms (defined as ZFarming) have been established or planned by activists and private companies in Berlin. These projects promise to produce a range of goods that could have positive impacts on the urban setting but also carry a number of risks and uncertainties. In this early innovation phase, the relevant stakeholders’ perceptions and social acceptance of ZFarming represent important preconditions for success or failure of the further diffusion of this practice.

A call for papers. Members of the UrbanFoodPlus interdisciplinary research project are proposing a session on Urban Agriculture at the 2016 Association of American Geographers Annual Meeting, to be held in San Francisco, California, March 29 – April 2, 2016.

Urban Agriculture: Interdisciplinary perspectives

Urban agriculture has received enormous attention from scholars over the past forty years. The particularly dense configuration of multiple resource access routes, legal technicalities and input and output market opportunities found in the city means that urban and periurban agriculture (UPA) is worthy of attention from multiple disciplines. There has been examination of its technical complexities (Amadou et al. 2012; Drechsel and Keraita 2014) alongside its social and political context (Cissé et al. 2005; McClintock 2010).

Urban Agriculture ranges from subsistence production and processing at household level to fully commercialized agriculture, and typically complements rural agriculture.

By Uwe R. Fritsche, Sabine Laaks, Ulrike Eppler

Excerpt:

Executive Summary:

Global land use is dominated by agricultural production, especially permanent grasslands for animal grazing, and for cultivating feed and food crops. The global food system (value chain of production and consumption of food as well as transport, processing etc.) changed radically over the last centuries, from subsistence agriculture and food production within and close to villages and cities to more rural production and urban consumption patterns nowadays, with a growing role of international trade.

The future of the global food system is rather uncertainty due to climate change impacts, diet dynamics, and yield developments. With cities and urban areas being “hotspots” of sustainability challenges and opportunities, urban food systems (as subsets of the global food system) are of interest.

Cities occupy a share of 0.5% of the global land area, and approx. 4% of the global arable land. Thus, urban food production cannot have a major direct impact on global land use, even if many cities will grow substantially in the future. Yet, there are specific agricultural land uses which can possibly be replaced by so-called Urban Agriculture (UA), and activities favoring urban food systems may have important indirect effects.

If all the lawns in this particular neighbourhood were replaced with crops, Johnson and his colleagues estimated that around 37% of the local population would be provided with all their vegetable needs for the year, assuming a 150-day growing season and a density of around 5000 people per square kilometre.

Excerpt:

“We estimated that the water demand could increase by more than 50% if urban agriculture were scaled to a significant degree,” said Johnson, who published the findings in Environmental Research Letters (ERL). “Water-smart agriculture – drip irrigation, rain-water harvesting and the like – would help manage the additional water demand and should be encouraged, particularly in regions experiencing water stress.”

Excerpt:

In this research, I took urban agriculture as a revenue generating and job creation activity by focusing on more market-oriented projects. I tried to describe individual urban agriculture business operations under the framework of the business model. An online questionnaire was distributed worldwide followed with statistical analysis. The questionnaire was designed using nine business building blocks from Business Model Canvas. Based on the reported business characteristics, a cluster analysis was performed in order to find patterns underlying the diversity of their businesses. In total 46 respondents from 18 countries across 6 continents completed the questionnaire and as sucht contributed to the results of my thesis.

In this issue of the Wesleyan Connection, we speak with Kate Weiner ’15, an anthropology and environmental studies major.

Q: Can you describe your thesis, “Reciprocity: Cultivating Community in Urban Agriculture”?

A: My thesis is an exploration of how community, identity and belonging interact in urban agricultural spaces, with my hands-on fieldwork with East New York Farms! serving as a case study for examining urban agriculture as a political project. Through melding creative non-fiction, feminist theory, community politics and environmental studies, the intention of my thesis is to provide a framework for understanding the various social, natural, socioeconomic and political factors that shape community-making within urban agriculture.

Resilience of UPA systems is being undermined by urban growth pressures

By Jon Padghama, Jason Jabbourb, Katie Dietrichc,
Urban Climate
Volume 12, June 2015, Pages 183–204

START and UNEP, along with several partners in Africa and South Asia, recently completed a 9-city assessment of urban and peri-urban agriculture that focused on the environmental dimensions of UPA. An article in Urban Climate synthesizing the findings of the assessment is available here. The article examines how poor governance, haphazard urban growth patterns and extreme events are amplifying impacts on UPA systems that may undermine the capacity of UPA systems to meet urban food as well as adaptation needs.

The assessments can be accessed at http://start.org/programs/upa

A Comparison between Bottom-Up and Hybrid Initiatives in New York and Amsterdam

By Beatriz Pineda,
Spanish urban planner and architect living in Amsterdam
This academic article is the final product of the Research Master’s in Urban Studies conducted at the University of Amsterdam (2012-2014).

Except from Abstract:

The numerous bottom-up initiatives appearing in Western cities, especially since the outbreak of the economic crisis in 2008, leads this research to focus on the future and endurance of these projects. Sometimes implemented and maintained only by citizens, other times supported by institutions, all of these initiatives aim at becoming successful and resilient. But how to measure the resilience of these grassroots efforts is still open to debate.

Understanding the role of urban and peri-urban crop production in urban food security at scale remains a major knowledge gap in the field of urban agriculture.

By A L Thebo1, P Drechsel and E F Lambin
Environmental Research Letters
Published 3 November 2014

Abstract

The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives. This lack of consistency makes quantification of the extent of this practice at the global scale difficult. This study instead integrates global data on croplands and urban extents using spatial overlay analysis to estimate the global area of urban and peri-urban irrigated and rainfed croplands.

Special Issue 1 2010

Abstract:

Urban agriculture is more or less marginalized within the theory, as well as within the conceptualization of sustainable development for Slovene towns. The spatial development plan of Ljubljana reflects the situation: permanent and temporary locations for gardens are to be situated all over the town, but there is no place for them in the inner city centre, in visually exposed sites, or near areas of cultural heritage. Yet, in the very inner centre of Ljubljana, 1.8 ha of allotment gardens are protected as cultural heritage. Therefore the case of these gardens, known as the Krakovo gardens, was used to discuss the perspective of urban agriculture in Ljubljana.
