Agriculture sciences

The agricultural and food industry is in a state of transition. Not only climate change, but also the increasing demand for healthy and sustainably produced products as well as new regulations and laws are forcing the industry to act. Specialists in the agricultural and food industry must therefore increasingly take international and interdisciplinary contexts into account. The Technical University of Munich (TUM) wants to address this development with a new Master's degree course in agriculture.

According to estimates, more than 900 million tons of residual biomass are produced throughout the European Union every year. Only a small proportion of this is recycled and fermented in biogas plants, for example. The majority, around 98%, ends up in, incineration plants or landfill sites. But this is now set to change.

Whether waste paper, cereal straw, food waste or sewage sludge: the use of residual and waste materials to manufacture new bio-based products is a cornerstone of the bioeconomy strategy and a precursor to a sustainable and resource-conserving economy. But which biomasses are available, which can be used for material or energy purposes and in what quantities are they available? Answers can be found in the resource database of the German Biomass Research Center (DBFZ). Researchers at the DBFZ have now revised the online platform.

An international study from 2022 shows that wetlands such as peatlands can store five times more carbon per square meter than forests and even 500 times more than the oceans. In Germany, peatlands have been drained in recent decades in order to be able to use the land for agriculture. This has not only destroyed the habitat of many plants and animals, but also an important CO₂ reservoir.

Soils are a vital resource and indispensable for ecosystems, climate and people. They not only store large amounts of carbon and water, but also provide plants with nutrients and people with food. However, industrial agriculture and the consequences of the climate crisis are putting soils under increasing pressure. According to a recent study, more than a third of agricultural land worldwide is degraded, in the European Union even more than 60%.

In view of global challenges, markets and trade relations, a sustainable bioeconomy can only succeed through international cooperation. In 2012, the Federal Ministry of Education and Research (BMBF) launched the "Bioeconomy International" initiative ("Bioökonomie International"), with the first projects starting the following year. Research alliances between German players and partners from non-EU countries are supported. The aim is to strengthen research cooperation with the world's best and tap into international innovation potential.

Meadows and pastures are important carbon sinks. The soils of so-called grasslands absorb a third of the world's carbon stock. Until now, researchers have assumed that carbon storage depends on the amount of plants growing on the soil. A recent study now disproves this assumption. In it, an international research team with the participation of Leuphana University Lüneburg examined the connection between the plant diversity of grasslands and carbon sequestration in soils in more detail.

The production of meat from animal muscle cells in a bioreactor is a promising way of securing the supply of protein-rich food for the world's growing population without harming the environment and climate. The first cell-based meat products have already been authorised in Singapore and the USA. What is possible on earth could also enrich space missions. This is shown by initial investigations by two independent research teams from the European Space Agency (ESA) in Germany and the UK, who have tested the cultivation of cultured meat in space.

Insects have long been part of the diet in many countries. They are not only rich in proteins, minerals and vitamins. They are also relatively easy to keep and produce significantly fewer greenhouse gases than pigs or cattle.

The Federal Ministry of Education and Research (BMBF) is investing around 50 million euros in innovative plant breeding research that is open to technology and methods as part of a new funding measure. The aim is to be able to guarantee a reliable, climate-resistant supply of high-quality, healthy and safe food.
