Subject:
capital; food availability; food deserts; food policy; grocery stores; philosophy; planning
Abstract:
... The focus of much of the research that examines the food system coming from the planning and policy fields is empirical and reductionist, following a rational technocratic planning epistemology. One critical failing in this approach is a general reliance on the state and its close ties to capital through a global neoliberal economic philosophy that is entirely enmeshed with the food system. This r ...

... The limited availability of foods that are free of pesticides has led Brazil to search for alternative production methods to meet the desires of consumers. Currently, organic cultivation represents a production system that complies with general expectations of producers and consumers. Organic cultivation is particularly interesting mainly because of its effect on plant secondary metabolite content ...

Abstract:
... Mid‐winter movements of up to several hundreds of kilometres are typical for many migratory bird species wintering in Africa. Unpredictable temporary food concentrations are thought to result in random movements of such birds, whereas resightings and recoveries of marked birds suggest some degree of site fidelity. Only detailed (e.g. satellite) tracking of individual migrants can reveal the relati ...

Yet some species groups might be more dependent on specific habitat features than on forest management per se. We therefore investigated the respective influence of forest management abandonment and habitat characteristics on ground beetles in si ...

We determined how home range size and refuge use by the Cen ...
