Contribution of Pulses to Agrobiodiversity in the View of EU Protein Strategy

Abstract

The importance of legume crops in global agricultural systems is inevitable; conversely, less than 4% of European agricultural lands are dedicated for these plants. Besides total loss of biodiversity, agrobiodiversity is also in danger. The production of legumes diversifies arable plant production and supports the nutrient management of the agroecosystem, as well as that of the whole ecosystem. Increasing soybean production area means that other pulses are grown on smaller areas, that means a reduced resiliency of the whole production system. Expanding environmental stresses of climate change and intensive agricultural practices are easier to counteract with help of diversity on species and on genetic level as well. As a consequence of climate change and targeted breeding of the last decade, agricultural lands appropriate for soybean production shows an increase in Europe. The self-sufficiency rates of the European Union concerning single protein sources shows fluctuations. The easier utilization of soy-based products as forage displaces the use of other pulses, which are traditionally produced as protein crops. Besides protein flow, these leguminous plants have an important role in different levels of agricultural systems as well. Several recent initiatives aim to reduce the serious protein exposure of the EU. These programs, beyond the introduction and technological development of soybean production, always mention the strengthening of the role of other pulses. In this study, the last decades of EU pulse utilization were analyzed, using crop yield, crop harvested area, certified seed yield, seed production area, number of registered varieties, and the number of scientific publications as indicators to summarize trends of EU field bean, field pea, lupin, chickpea, lentil, and soybean production in the view of targeted protein initiatives.
