Pseudomonas syringae is a bacterium that causes various plant diseases and damages agriculture by infecting crops. Like other microorganisms, the bacterium is also able to produce a variety of biologically active natural substances.
Spruce forests once characterised the landscape of Germany's low mountain ranges - today they are struggling to survive. Climate stress, bark beetles and extreme weather conditions have taken their toll on the robust conifers. The SURVEY joint project heralds a new era in forest research: in the future, research will be conducted directly in the forest instead of in the laboratory.
Digitalisation in agriculture is progressing. Field robots and the like can not only make work easier and more efficient. Modern monitoring technologies such as radio chips and sensors can also ensure higher yields in animal husbandry. However, such innovations are cost-intensive and rarely affordable for small farms.
Regenerative agriculture is becoming increasingly important as it offers both ecological and economic benefits. This agricultural approach specifically promotes the build-up of humus in the soil, which binds carbon, improves soil quality, strengthens biodiversity and enables stable yields. In contrast to conventional agriculture, it regenerates natural ecosystems instead of merely utilising them.
Yellow rust, also known as stripe rust, is caused by the fungus Puccinia striiformis f. sp. tritici and is one of the most dangerous diseases in wheat cultivation. Around 88% of global bread wheat production is potentially affected by the pathogen. An international research team led by the University of Zurich (UZH) has now identified two genome segments in Asian wheat varieties that give the plants natural resistance to the disease.
Droughts and other consequences of climate change are putting a strain on agriculture. This is why the cultivation method of agroforestry - already long established in the tropics and subtropics - is increasingly being used in European agricultural systems. This is because the integration of trees and shrubs with arable farming and livestock farming on the same land promotes biodiversity and protects against climate risks.
Photovoltaic (PV) systems are no longer only installed on roofs, but also on farmland and grassland. A growing variant of this is agrivoltaics - the generation of solar power on agricultural land: solar panels between fruit trees, vines or cows. The study published in the journal Land Use Policy now shows that agrivoltaics are better accepted by the population than normal ground-mounted solar systems. This result is based on an online survey of almost 2,000 people from Germany.
The way in which fields are cultivated and food is produced has a lasting impact on the environment and climate. Around a third of global greenhouse gas emissions, biodiversity loss and soil degradation are caused by global agricultural and food systems. The Leibniz research network ‘Green Food - Healthy Society’ is now providing a new systemic approach to tackling these challenges.
Forests are both a carbon sink and a source of raw materials. However, the condition of trees has not only deteriorated in Germany. Aridity, drought and pests as well as large-scale deforestation in the tropics are jeopardising ecosystems worldwide and fuelling global warming. On 29 April 2025, the European Space Agency (ESA) launched BIOMASS, a satellite designed to monitor the Earth's green lungs.
