Making use of the plant's defences

 

Last summer, heat and drought have afflicted farmers in many places and caused enormous harvest losses. The damage caused to farmers in Germany was estimated by the Federal Ministry of Food and Agriculture at 770 million euros.
Extreme weather conditions make plants more susceptible to disease and pest infestation. This also endangers wheat production in Germany and large parts of Europe.

Biodiversity under attack

New technologies such as field robots are already making agriculture more efficient and sustainable. New habitats for insects and other animals are being created with flower strips or mixed cultivation of crops. This contributes to the protection of biological diversity. But can all these measures halt the global loss of biodiversity? Apparently not.

Meta-analysis: higher yield, less diversity

According to the Federal Statistical Office, slightly more than half of Germany's acreage was used for agriculture in 2016. Farmers are using modern machinery and pesticides and fertilizers to increase yields. Studies confirm: More intensive farming is detrimental to the environment and above all threatens species diversity. But a meta-analysis now shows at what a cost for nature a bountiful harvest actually comes.

EU: Plant raw materials mostly imported

Whether palm oil, cotton or soy: many raw materials from plants used in Germany for the production of cosmetics, textiles, biodiesel or animal feed have to be procured from abroad. But where do the raw materials come from and what are the environmental consequences? An international study led by the Institute for Ecological Economics at the Vienna University of Economics and Business Administration (WU) provides answers. Researchers from the University of Bonn were also involved.

More variety for rapeseed fields

In many ways, rapeseed is a very special crop. For one thing, it is still relatively young - oilseed rape originated only about 1,000 years ago by a random cross between turnip (Chinese cabbage) and cabbage. On the other hand, with its 38 chromosomes Brassica napus has a very large and complex genome, with little of it known until a few years ago. Now, the yellow-flowering oilseed is used in many industrial areas, but there is a risk that today's rape varieties will soon no longer meet the harvest and environmental requirements.

Milk money - what is it worth?

Milk and dairy products such as cheese or yoghurt are some of the food-favorites in Germany and their sales have been steadily increasing for years. Especially so-called functional dairy products such as digestive yoghurt drinks or cholesterol-lowering spreads have conquered the market in recent years. But what do these products really contain, what exactly are the health-promoting components of milk and how can they be used specifically? And last but not least: how and why does the consumer decide to buy a product?

How climate change impacts fish species

Herring, pike-perch or salmon: fish is among the top healthy foods. The demand has been high for years. According to the Federal Statistical Office, in 2018 each person in Germany consumed about 13.7 kilograms. But Myron Peck knows that climate change will dictate which fish ends up on the plate in the future.
