Intensive agriculture has created several problems in cropping systems that threaten the sustainability of agricultural production. In order to design new cropping systems, a new approach is emerging to support the transition toward sustainable agriculture: a co-design and co-evaluation process that involves stakeholders in the agrifood chain. The present work therefore describes the co-design and co-evaluation process that was followed to design a highly diversified cropping system in a Mediterranean environment. The different systems that were co-designed include the reference system, with wheat and barley in rotation, as well as three diversified systems that were also proposed and co-evaluated: the rotation of wheat, oil seed rape, and barley (DIV1); the rotation of wheat, pea, and barley (DIV2); and the rotation of wheat, intercrops of barley-common vetch, and barley (DIV3). The best system that was selected from the different stakeholders was the DIV3, as it had the highest evaluation of the stakeholders using agronomic, environmental, and socio-economic criteria.

The intensive agriculture that is used in many countries has led to a reduction in biodiversity and the deterioration of the environment. Therefore, it is important to increase the adoption of cropping systems with high biodiversity. The objectives of the present study were the following: 1. assess the performance and sustainability of novel highly diversified production systems compared to the current traditional system and 2. provide quantitative economic and ecosystem service information for farmers, extension workers, and policy makers in order to support the development of sustainable and resilient high species cultivar/landrace diversification (HSD) production systems. The rotation of wheat–pea–barley was a system with low energy inputs and high outputs, significantly increasing the energy efficiency. Also, the same system demonstrated better economic and environmental indices, making it a suitable cropping system for Mediterranean areas. [ABSTRACT FROM AUTHOR]

The saffron sector as a sustainable farming system plays a primordial agro-ecological and socio-economic role in the Anti-Atlas region in Morocco. Under the Green Morocco Policy, the saffron area has more than tripled; however, productivity is still very low. To evaluate the efficiency of Moroccan saffron farming and its determinants, we estimated a stochastic frontier model using survey data collected in the production area. The results show that saffron farms suffer from technical inefficiencies. More time dedicated to saffron field operations, a higher number of saffron plots and a greater distance to the urban centre increase farm efficiency, while the age of the farmer and the presence of off-farm activities decrease it. Building on our results, we argue that the new policy "Generation Green" should be focused on younger farmers as they are more likely to improve their skills and crop management techniques. To upscale the adoption of saffron as a sustainable farming system, an improvement in farmers' market access is necessary which would facilitate farm specialisation, convert saffron to a major source of income and reduce dependence on off-farm activities. Strengthening the role of saffron cooperatives could represent an important step in this direction, but this requires improved knowledge dissemination and technology access. [ABSTRACT FROM AUTHOR]

European countries have set ambitious targets to reduce the risks of pesticide use. Achieving these targets will require a large proportion of farmers to adopt sustainable crop protection practices. However, how to enable this transition and what are the best policies to support farmers remain open questions. Here, we provide a coherent review of existing evidence and new insights into farmer decision-making and policy analysis in the context of the transition to more sustainable crop protection. We synthesise and extend the empirical evidence and the conceptual and methodological foundations to examine farmers' decisions to adopt sustainable crop protection and to assess the potential of different policy measures to support this transition. Our analysis focuses on European agriculture. We provide a framework and synthesise evidence by reviewing the literature and combining agronomic and economic perspectives. We focus on three issues: i) indicators for empirical analyses of adoption of sustainable crop protection practices; ii) behavioural perspectives on farmer adoption; iii) insights into methodological approaches for assessing adoption of sustainable crop protection practices and related policies. We have identified four main findings and implications. First, sustainable crop protection practices consist of combinations and bundles of individual measures that are not currently regularly considered in policy instruments and policy analysis. Second, definitions of adoption should move from simple adoption metrics to impacts, for example on pesticide risk reduction. Third, behavioural factors are highly relevant to farmers' adoption decisions, but are currently under-researched and under-represented in the field of sustainable crop protection practices. Fourth, the tools currently used for policy analysis do not allow these key aspects to be represented. We draw policy conclusions. Our analyses help guide policy decisions to achieve pesticide use and risk reduction objectives, and have implications for pesticide policy in Europe and beyond. We identify gaps in current conceptual and methodological approaches, promising avenues for future research, and ways to make results more coherent and comparable. Our analysis thus provides new insights and templates to guide future research and policy analysis on the adoption of sustainable crop protection approaches.
