Urban agriculture should be treated as a serious farming method to help meet the global ambitions of the United Nations' Sustainable Development Goals for 2030, according to Flinders University researchers.

Well-managed food production both on city fringes and built-up areas is a vital part of building healthy communities—while also enhancing environmental and social resilience in an increasingly urban world, they say in a review of urban agriculture in the journal Urban Forestry & Urban Greening.

"While not overstating the benefits, urban agriculture clearly has a role to play in achieving , urban sustainability, and fostering ," says Ph.D. candidate Hannah Thwaites, lead author of the study.

"We argue that more widespread and sustainable urban agriculture can help to address key issues of hunger, urbanization, and finite resources to positively support people and the planet."

The Flinders and University of Adelaide research found that growing food within urban areas from backyard scale and beyond can directly help to meet the 2030 completion of the UN's , in particular Zero Hunger (SDG 2), Sustainable Cities and Communities (SDG 11) and Responsible Consumption and Production (SDG 12).

Applied effectively, urban agriculture can also help multiple targets sitting under a further nine of the 17 SDGs—Zero Poverty (SDG 1), Good Health and Wellbeing (SDG3), Quality Education (SDG 4), Gender Equality (SDG 5), Clean Water and Sanitation (SDG 6), Decent Work and Economic Growth (SDG 8), Reduced Inequalities (SDG 10), Climate Action (SDG 13) and Life on Land (SDG 15).

Urban food production can occur in, around, under and on top of infrastructure—on private and public land—for consumption, distribution and sale.

The diversity of urban agricultural forms—from residential, community and allotment gardens, to rooftop farms, school gardens, and various scales of commercial farms—appear to add to its impact, and certainly its accessibility.

Along with providing healthy, affordable fresh food and opportunities for social connectedness and , the environmental benefits include improved resource use and carbon footprint.

"Urban agriculture reconnects people with their , builds resilient communities, improves , and the positive environmental outcomes includes mitigating against the effects of climate change," adds Professor of Soil Ecology Tim Cavagnaro, a co-author of the study.

To avoid an advocacy bias, the authors point out potential risks of urban farming, such as heavy metal contamination, along with mitigative strategies such as using raised garden beds and root barriers.

"Ultimately, contextualized and nuanced approaches are critical for achieving sustainable development aims and 's multidimensionality and diversity lends itself to tailored solutions," Thwaites says, adding her research is now investigating what helps or hinders engagement in this farming practice to ensure its benefits can be experienced by everyone.

"I'm encouraged by the abundance of food garden ventures around Adelaide, including those that help showcase how community resilience can be fostered from the home garden."
