Sustainable agriculture issues explained by differentiation and structural coupling using social systems analysis

In spite of many initiatives to increase sustainability, agriculture moves in the opposite direction with increased pesticide impacts and decreased nature quality. Here, we propose that this issue is not mainly due to lack of agronomic knowledge, but due to the lack of knowledge on social processes of specialization and differentiation. Here, we review the challenge of agriculture and sustainable development based on Niklas Luhmann theory of social systems. We focus on the concepts of differentiation and structural couplings. We use two forms of analysis, discursive differentiation and organizational differentiation, which mutually support each other. First, we analyze discourse categories, named ‘semantics’ in the social systems theory, such as ‘environmental problems’ and ‘food safety’. We then look at how these discourses are related to the discourse of sustainability. Secondly, we describe different forms of organizational differentiation within agriculture and food, e.g., in the pig production chain. Here, we show how sustainability problems can be seen as an unavoidable consequence of the ‘decouplings’ that follow these differentiation and specialization processes. Finally, using the insights from social systems theory, we discuss how these sustainability problems might be mitigated by the following three forms of new structural couplings: (1) functional couplings of organizations to generalized semantic perspectives on e.g., environment and nature, which can reintroduce the sensibility of agri-food systems to their surroundings, (2) structural couplings between organizations that can handle other dimensions than price and quantity, including couplings mediated by labels and network couplings such as partnerships that provide options for co-evolution, and (3) second order couplings to polyocular semantics such as the sustainability semantic; that is, semantics that have their strength and challenge in the fact that they are multiperspectival and must remain indeterminate. Social systems analysis is a novel and strong tool to analyze social differentiation processes in agriculture. Social systems analysis provides researchers, farmers, and companies new ways to understand the sustainability problems that these differentiation processes produce.
