Regulations for organisms and products to which genome-editing technologies are applied are increasing in diversity, with the path-dependent effect of previous regulations for genetically modified organisms. Regulations for genome-editing technologies are a patchwork of international regulations that are difficult to harmonize. However, if the approaches are arranged in chronological order and the overall trend is examined, the regulation of genome-edited organisms and GM food products has recently been trending toward a middle ground which can be characterized as “limited convergence.” There is a trend toward the adoption of two approaches: one that considers GMOs but tries to apply simplified regulations and another that excludes them from the scope of regulations as non-GMOs but requires confirmation. In this paper, we discuss why there is a tendency toward convergence of these two approaches and examine the challenges and implications of these two approaches for the governance of the agricultural and food sectors.

Cell-based meats have been discussed in terms of improving sensory factors for consumer acceptance and remedying the environmental problems of conventional livestock production. The improvement accompanies the modification of the production process and the consumption habit regarding cell-based meats. This review analyzed the current status of policies that promote cell-based meats, the related literature, and policy frameworks for the regulation and promotion of cell-based meats in the European Union, Singapore, the United States, Israel, and Japan. Sample selection was based on language, that is, English and Japanese. Further selection was exploratory to analyze the diverse degree of the integration of cell-based meats in policies. The region and countries were selected as leading cases, thereby enabling a policy comparison because they host global corporations that produce cell-based meat. The literature review examined peer-reviewed social science articles from 2013 to early 2022 on policies that promote cell-based meats. The results of the policy surveys revealed that regulations focused on the safety of and measures to display these novel foods by conducting a premarket assessment. These regulations are the basis for developing cell-based meats. Furthermore, some countries and the region being studied justified their support for cell-based meats by implementing action plans for decarbonization and food security. However, unclear communication regarding the nomenclature of cell-based meats is likely to slow down the development of cell-based meats. Moreover, religious beliefs and other cultural perceptions, including animal welfare, leave much room to research such promotion. Similarly, environmental impact assessments of cell-based meats demand further considerations and discussions to accompany evidence-based policymaking for cell-based meats.

To investigate the influence of food culture on the acceptability of meat substitutes, in 2023 we conducted a questionnaire survey on men and women aged 18–69 years (N = 1681) in Japan, a country with a food culture that regards soya as a meat substitute, focusing on ‘meaning’ in the theory of practice. Analysis of three groups—a flexible group who accept foods processed from soya as meat, a strict group who do not accept such foods as meat, and an intermediate group—showed that the flexible group tended to be more positive about the consumption of meat substitutes than the other groups. However, the flexible group was not simply more accepting, as they expressed aversion and anxiety in response to other questions. Food culture, i.e., what is understood to be meat, influences the acceptability of alternative meats. When examining the social acceptability of meat alternatives in the future, it is also important to look at social practices and historical and cultural backgrounds in a multilayered way, in addition to factors that have been emphasized in previous studies, such as consumers’ decision-making process.

In North America, we can find various attempts to change local food systems by considering the viewpoints of multiple stakeholders. In particular, the concepts of food policy (Tim Lang) and citizen's engagement are key. In this paper, I will describe how these ideas have been discussed in North America by referring to various practical attempts to solve issues of local food systems, such as food policy councils, urban food policy, food charters, and so on. After describing the details of these activities and implications to food access issues, I argue that we need to consider the multi-functionality of food in urban society, and that this idea encourages us to develop a more coordinated relationship between food systems and urban planning in local contexts. Understanding the multi-functionality of food leads us to reconsider the nature of food from the viewpoint of “food as commons” rather than food as commodity.

Genome editing is being applied in various fields of life sciences, such as medicine, agriculture, food and energy. Regarding the regulatory status of genome editing in Japan, policies are being issued by the Ministry of Health, Labor and Welfare and the Ministry of the Environment, and applications to the fields of agriculture and food are being widely considered. However, there has hardly been any explicit discussion on the differences between applications for plants and animals. We argue there are several points that should be taken into account. In this paper, we clarify the unique regulatory issues that separate genome edited animals from plants, in particular, safety assessment, consumer perception, and animal welfare.
