"Current and future yields of grain legumes across Europe"

Nicolas Guilpart - AgroParisTech, France

A presentation given during Webinar 2 "Optimising Legume Production" of the 8 Webinar series ‘European Legumes in Transition’ 20 April 2021

Because of the number of agronomic, environmental and nutritional services they provide, legume crops have been proposed as a key lever of the agro-ecological transition. But with less than 5% of agricultural land in 2018, legume production area remains very low in Europe. In this context, identifying suitable areas for legumes production under current and future climate appears essential. To this aim, within the LegValue project we developed (i) the European Grain Legume Dataset, a unique dataset of field experiments involving legumes in Europe (~5000 yield observations in 21 countries), and (ii) a data-driven approach that combines observed crop yields in field experiments with machine learning techniques to model grain yield of five grain legumes (soybean, field pea, faba bean, chickpea and lentils) from climate inputs in Europe. Yield projections suggest high suitability for most crops under historical climate and a likely strong impact of climate change. Implications of these projections for legume development in Europe will be discussed.
