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 …
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 …
