“…Zoning may show spatial inconsistency. When prime productive farmlands are located close to urban areas and face higher pressure, they may be less protected, as in the South of France [58]. In Wisconsin, for instance, exclusive agricultural zoning is more likely to be adopted in municipalities located outside conurbations [59].…”

This paper reviews the recent literature dealing with farmland protection (FP) policies in developed countries from a planning perspective, with a specific focus on the Mediterranean region. It provides coverage of French language papers that may have been omitted in previous reviews. While the Mediterranean is often pointed out as a region with acute challenges related to food security and a lack of effective planning policies, the literature underlines that issues related to FP policies are similar across the world. Hence, this review may bring valuable insights for more sustainable management of farmland on the urban fringe. It maps several interesting areas of research concerning the often implicit and disparate rationales of FP policies as well as the barriers and potential avenues for improvement for FP. It highlights that FP cannot rely merely on transferring policy tools that have proven successful elsewhere. It also reveals that land policies do not always take into account the specific needs of farming systems, as they often focus on land rather than on agriculture. Further research is thus needed to reveal the interaction over time between the use of certain FP tools and the unique local features of urban fringe agriculture. This review may be of interest to students and scholars, but also to practitioners, policy makers and local groups looking for innovative, more flexible or locally suited farmland protection programs.

“…Population growth in the Occitanie Mediterranean coast has been high for several decades (i.e., average growth of 1.4% per year between 1999 and 2006). Such growth has spawned rapid and uncontrolled urban sprawl at the expense of agricultural land (e.g., 200 km 2 between 1997 and 2009) (Balestrat et al, 2011), which induced irreversible losses of high‐potential soils. To control and mitigate this development, land planners need to be advised of which soils should be protected from urbanisation to best ensure food self‐sufficiency of the Occitanie Mediterranean coast on the long term, while minimising the negative impact of agricultural activities on the environment and optimising the role of soils in carbon sequestration (Rabot et al, 2022).…”

Pedometricians have spent a lot of effort on mapping soil types and basic soil properties. However, end‐users typically need a more elaborate soil quality index for land management. Soil quality indices are typically derived from multiple individual soil properties by evaluating whether specific criteria are met. If this is based on individually mapped soil properties, then an important consequence is that cross‐correlations between soil properties are ignored. This makes it impossible to quantify the uncertainties associated with the mapped indices. The objective of this study was to map a soil potential multifunctionality index for agriculture (Agri‐SPMI) over a 12,125 km2 study region located along the French Mediterranean coast to help urban planners preserve soils of the highest quality. The index considered the ability of soils to fulfil four functions under five land use scenarios. A binary map represented each soil function fulfilment for a given scenario. The final soil quality index map was the sum of the 20 binary maps. A regression cokriging model was developed to map the basic soil properties first individually from legacy soil data and spatial soil covariates using a random forest algorithm, and next, interpolate the residuals using cokriging and the linear model of coregionalisation. The mapping uncertainties of soil properties were propagated by calculating the soil quality index over 300 stochastic simulations of soil properties derived from the linear models of coregionalisation. Results showed a poor prediction accuracy of the quality index, mainly because some soil properties were poorly predicted (notably available water capacity and coarse fragments) and used in combination with extreme thresholds that defined land suitability. Overall, the uncertainty was correctly quantified because the stochastic simulations reproduced the width of the observed distribution well, but the shapes of the distributions differed considerably from those of the observations. We envisage some ways for improvement, such as creating probability maps instead of the mean from simulations, and changing the prediction support from point to area. Highlights The study mapped a soil quality index (Agri‐SPMI) to help preserve soils of highest quality along the French Mediterranean coast. The Agri‐SPMI considered the ability of soils to fulfill four functions under five land use scenarios, derived from multiple individual soil properties. A regression cokriging model was developed to map the basic soil properties, followed by interpolating the residuals using cokriging and the linear model of coregionalisation. The study accurately quantified mapping uncertainties using stochastic simulations, but the soil quality index prediction accuracy was poor, with suggestions for improvement.

In a context of increased land and natural resources scarcity, the possibilities for local authorities and stakeholders of anticipating evolutions or testing the impact of envisaged developments through scenario simulation are new challenges. PRECOS's approach integrates data pertaining to the fields of water and soil resources, agronomy, urbanization, land use and infrastructure etc. It is complemented by a socio-economic and regulatory analysis of the territory illustrating its constraints and stakes. A modular architecture articulates modeling software and spatial and temporal representations tools. It produces indicators in three core domains: soil degradation, water and soil resources and agricultural production. As a territory representative of numerous situations of the Mediterranean Basin (urban pressures, overconsumption of spaces, degradation of the milieus), a demonstration in the Crau's area (Southeast of France) has allowed to validate a prototype of the approach and to test its feasibility in a real life situation. Results on the Crau area have shown that, since the beginning of the 16th century, irrigated grasslands are the cornerstones of the anthropic-system, illustrating how successfully men's multi-secular efforts have maintained a balance between environment and local development. But today the ecosystem services are jeopardized firstly by urban sprawl and secondly by climate change. Pre-diagnosis in regions of Emilia-Romagna (Italy) and Valencia (Spain) show that local end-users and policy-makers are interested by this approach. The modularity of indicator calculations and the availability of geo-databases indicate that PRECOS may be up scaled in other socio-economic contexts.
