Analysing the relationship between yields and farmers' incomes to help the design of more sustainable cropping systems

Farmers often grow only the few high-yielding crops in the area, and target maximum yields through high levels of inputs. These practices are based on the assumption of a positive relationship between productivity and profitability over a wide range of cropping systems (Woo et al., 2020; Erythrina et al., 2021). Part of the correlation between productivity and profitability could be related to differences in production situation and therefore yield potential, i.e. characteristics that do not depend on farmers’ decisions. For a given production situation, the systems with the highest profitability and the best environmental sustainability could be systems with moderate yields. The objective …

Mobiliser les agroéquipements et le numérique pour des systèmes de culture sans pesticides

Chapitre 6 Disponible gratuitement en ebook; International audience; Les agroéquipements et le numérique sont des leviers essentiels pour développer des systèmes de culture sans pesticides. Des innovations en matière de précision d’exécutionet d’adaptabilité des équipements sont attendues. En parallèle, le développement des capteurs va permettre d’améliorer la surveillance des bioagresseurs, mais égalementcelle de l’ensemble du système de culture et de son environnement. Les capteurs, associés aux nouvelles technologies de l’information, pourront également contribuer àl’émergence de filières sans pesticides et facilitant la traçabilité du champ à l’assiette. Des questions vont néanmoins se …

Valuing the DEPHY network datasets to analyze relationships between crop diversity and pesticide use, to help the design of sustainable cropping systems

Overuse of pesticides is one of the main hanging issues which impede sustainable crop production. Despite a rapid growing body of research assessing the impact of agricultural diversification (practices/crop/ non-crop/ microorganism diversity) on the ecological perspective of the cropping system (e.g. ecosystem services and biodiversity), a synthesis on the agronomical impact is less documented. A few researches conducted on an experimental scale has proved that crop diversity can reduce agronomical input such as pesticides. However, those results are context-dependent, so it is hard to conclude on a broader view. Therefore, a quantitative analysis is missing about the relationship between …
