Sustainable agrifood systems are critical to averting climate-driven social and ecological disasters, overcoming the growth paradigm and redefining the interactions of humanity and nature in the twenty-first century. This Perspective describes an agenda and examples for comprehensive agrifood system redesign according to principles of sufficiency, regeneration, distribution, commons and care. This redesign should be supported by coordinated education and research efforts that do not simply replicate dominant discourses on food system sustainability but point towards a post-growth world in which agroecological life processes support healthy communities rather than serving as inputs for the relentless pursuit of economic growth.

This paper examines the potential demand of Japanese consumers for eco-labeled seafood products. Ecolabeling programs are known to promote sustainableˆsheries such as sound resource management and environmental conservation. Conjoint analysis is conducted to estimate consumers' preferences for eco-labeled products.The estimated parameters of the conditional logit model showed that consumers have positive preferences for products certiˆed as``domestic'' or``eco-label''. Furthermore, while the value of marginal willingness to pay (MWTP) for domestic products is the highest, MWTP for eco-labeled products is the second highest among various attributes of seafood products. These results suggest that a certain level of demand exists for eco-labeled seafood products in Japan.

Individual agroecological farms can act as lighthouses to amplify the uptake of agroecological principles and practices by other farmers. Amplification is critical for the upscaling of agroecological production and socio-political projects emphasizing farmer sovereignty and solidarity. However, territories are contested spaces with historical, social, cultural, and economic contexts that can present challenges to the effectiveness of farmer lighthouses in catalyzing localized agrarian change. We explore these amplification dynamics through fieldwork in a particular region of Japan employing interviews and data derived from an assessment of nine farms using ten amplification indicators. The indicators include social organization, participation in networks, community leadership, and degrees of dependency on policies or markets among others, as well as degree of adoption of on-farm agroecological practices, all of which capture farmer lighthouses' potential to amplify territorial upscaling. At the same time, we trace the historical development of a previous generation of Japanese farmer lighthouses practicing organic agriculture in alignment with agroecological principles that experienced, to varying degrees, push-back, co-option, and successful territorialization in rural communities. We find that many of the same social and cultural territorial dynamics are still influential today and affecting the amplifying effect of agroecological farmer lighthouses, but also find examples of new clustering around lighthouses that take advantage of both the historical vestiges of the previous generation's efforts as well as contemporary shifts in practice and agrarian orientation. This research calls for a detailed dissection of the dynamic and contrasting processes of agroecological territorialization and the ways in which diverse contexts shape agroecological upscaling.
