PDF Urbanisation Migration and Food System Transformations Concepts Biology Diagrams Impacts of urbanisation on food systems. In this section, we discuss the most important impacts of urbanisation on food systems which, in turn, affect rural livelihoods: the overall growth of urban food demand; purchasing power and related food preferences; increasingly complex food value chains; and direct and indirect land use changes.
The dependence of many very large concentrations of urban populations on long international supply chains for food, fuels and most intermediate and final goods makes them vulnerable to disasters in locations that supply these or buy their products, and also to rising fuel prices. Any discussion of the ways in which urbanization may affect Global change scenarios such as climate change, natural disasters, geopolitical crises, and pandemics are drawing increasing attention to vulnerabilities in global food supply (Jansma and Wertheim-Heck, 2022).The rampant expanding urbanization and industrialization emphasize the "urban land teleconnection," which links urban consumption with its effects on cultivated land (not necessarily
Urbanization and its implications for food and farming Biology Diagrams
Dietary changes, such as increasing diversity and rising consumption of non-grain foods, processed products, and prepared foods, typically accompany urbanization. As urban markets expand, food supply chains and markets are also transformed—for example, the case of teff in Ethiopia (Minten et al., 2016). Food loss and waste within the food system depend on many factors, but the level of economic development is a strong predictor: Preconsumer food losses within the supply chain are more prevalent in developing countries, whereas postconsumer food waste is a bigger issue in high-income countries . Urbanization may actually be beneficial for
These studies place less emphasis on the internal organization of the food system within cities, on the effects of forms of urbanization or on city dwellers' behaviour. However, the non-sustainability of urban food systems is also a result of urban lifestyles, spatial configurations and consumption practices. The dependence of many very large concentrations of urban populations on long international supply chains for food, fuels and most intermediate and final goods makes them vulnerable to disasters in locations that supply these or buy their products, and also to rising fuel prices.

Writing in Science, Seto calls on the research community to move beyond urbanization's direct effects on diet and to focus on its indirect effects on resource use and the environment, including the amount of energy required for food production, transport, packaging, and cold storage. "This link between urbanization and food systems has not been fully explored in a systematic, empirical way
