At the crossroads of spatial planning and agriculture, this article explores how planning practices impact on-farm diversification strategies in peri-urban Mediterranean France. It focuses on farm building permit applications, statistically analyzing a database of 860 buildings applied for and interviewing local authorities and farmers’ representatives. Results show the large proportion of applications related to reterritorialization of food systems, development of recreational activities, and production of green energy. These on-farm diversification trends highlight the transformation of peri-urban areas from a natural or agricultural landscape into a multifunctional landscape, posing several planning challenges. Planners don’t know how to assess whether a new building is really essential for farming, or to find the right trade-offs to support farming dynamics while limiting soil sealing. Their assessment criteria generally favor large, full-time, and economically viable farms. Comparing two provinces’ planning practices, we observe significant differences in interpretation of national law, with incoherent or unharmonized criteria applied especially when assessing professional farming activities, new dwellings, and solar energy projects. We also highlight two potential obstacles to farmers’ generational renewal and agroecological or food transitions: i) lack of transparency regarding the rules and the decision-making processes behind building permit assessment, and ii) the frequent rejection of applications for multi-purpose premises and lightweight, mobile, or dismantlable structures. Such results point to the role of planners in transforming peri-urban landscapes and the need for more consistent regulation of new farm buildings, supporting and not hindering farm adaptation strategies and the multifunctionality of peri-urban areas.

规划实践是否阻碍了法国地中海郊区的农场多样化？


在空间规划和农业的十字路口，本文探讨了规划实践如何影响法国地中海郊区的农场多样化战略。它侧重于农场建筑许可证申请，对申请的 860 栋建筑物的数据库进行统计分析，并采访地方当局和农民代表。结果表明，很大一部分应用与食品系统的再领土化、娱乐活动的发展和绿色能源的生产有关。这些农场多样化趋势凸显了城郊地区从自然或农业景观转变为多功能景观，这带来了一些规划挑战。规划者不知道如何评估新建筑是否真的对农业至关重要，也不知道如何找到正确的权衡来支持农业动态，同时限制土壤密封。他们的评估标准通常有利于大型、全职和经济可行的农场。比较两个省份的规划实践，我们观察到对国家法律的解释存在显著差异，特别是在评估专业农业活动、新住宅和太阳能项目时，应用了不连贯或不协调的标准。我们还强调了农民代际更新和农业生态或食品转型的两个潜在障碍：i） 建筑许可评估背后的规则和决策过程缺乏透明度，以及 ii） 多用途场所和轻型、可移动或可拆除结构的申请经常被拒绝。 这些结果表明，规划者在改变城郊景观方面的作用，以及需要对新的农场建筑进行更一致的监管，支持而不是阻碍农场适应战略和城郊地区的多功能性。
