Agriculture and forestry

Whether wheat or corn, after two successive hot summers, farmers in many places are threatened with enormous crop failures this year due to persistent drought. Plants suffer from drought stress because the soil dries out and the root system is not supplied with sufficient water and nutrients. The challenges of climate change are therefore causing researchers to work hard to find promising scenarios for agriculture in the future. 

Many people suffer from food allergies. According to estimates by the German Allergy and Asthma Association (DAAB), around six million children and adults are affected in Germany alone. Peanut allergy is particularly widespread. So far, allergy sufferers have had to do without allergy-causing foods such as peanuts or mustard, as the condition cannot yet be cured.

Based on information from 91 countries and 27 international organizations, analysis of global literature and data, as well as contributions from over 175 authors and reviewers, "The State of the World's Biodiversity for Food and Agriculture" assesses biodiversity and its management worldwide. Important drivers for both positive and negative trends in the conservation and sustainable use of biological diversity are identified and production practices that promote biodiversity are presented.

Along with soya and corn, sugar cane is one of the most important crops in Brazil. It is used to produce not only sugar but also biofuels such as ethanol. However, processing produces enormous amounts of bagasse - fibrous remains - which up to now were not used efficiently. Instead, the lignocellulosic residual material is burnt in inefficient incinerators and usually disposed of in landfills or scattered on fields. But ash is more than just burned biomass. It contains nutrients such as phosphorus, which are essential for plant growth.
