Citrus fruits, coffee and avocados: The food on our tables has become more diverse in recent decades. However, global agriculture does not reflect this trend. Monocultures are increasing worldwide, taking up more land than ever. At the same time, many of the crops being grown rely on pollination by insects and other animals. This puts food security at increased risk, as a team of researchers with help from Martin Luther University Halle-Wittenberg (MLU) writes in the journal “Global Change Biology”. For the study, the scientists examined global developments in agriculture over the past 50 years.
