Agriculture and the food system ramifications account for around 30% of global anthropogenic greenhouse gas (GHG)
emissions. Yet, beyond the usual urban food-related metabolic approaches
to carbon emissions (globalization of diets, value chains, nutrient balances,
etc.), additional structural and spatial dimensions to the conception of this
problem need to be outlined. This study proposes a transdisciplinary and
multidimensional framework to support the interpretation of food-related GHG
emissions induced by different aspects of urbanization; this was done through a
bibliographic review considering a broad sample of studies while identifying
leading authors and schools. Two major categories of scholarly praxis were
used: urban metabolism and urban morphology. In this process, it was found that
there is a gap between the perspectives of urban planning and design outlets
and the research programs derived from the fact that the urban metabolism
stream of studies is simpler to isolate, fund, and implement when compared to
the remarkably long-term oriented planning needed to embark on urban morphology
measures. Moreover, there is currently a biased tilt toward urban studies in
terms of research investments and cases such as the agropolitan territories
have been disregarded despite their already proven results. This could be
solved if when using the term urbanization, it is understood that
de-ruralisation is an inevitable, and simultaneously occurring mechanism. It
then follows that urban spatial planning should also be complemented by rural
spatial planning to achieve effective
integrated solutions within relevant rural-urban science-policy interfaces.
