Long droughts, heavy rainfall, hailstorms, cold and late frost – extreme weather events cause substantial damage in the agricultural sector. Researchers at the Leibniz Centre for Agricultural Landscape Research (ZALF) are investigating in a new project to what extent such extreme weather events can be better predicted and damage prevented or limited.
The aim of the project funded by the Federal Ministry of Food and Agriculture (BMEL) is to develop an extreme weather monitoring and risk assessment system (EMRA). As a first step, specific risks for agriculture, such as crop failures or soil erosion, are to be analysed and thus better assessed through the systematic recording of actual extreme weather events and their damage.
The main focus is on the consequences of hail, cold and late frost, waterlogging, heavy rainfall, drought and heat. In the case of waterlogging and heavy rainfall, immediate risks to the ecosystem are investigated and local management measures derived from these.
These are intended to prevent soil fertility from being endangered by erosion, for example, and to prevent adjacent ecosystems from being polluted by pesticide and fertiliser inputs. Based on two model regions and cultures, Apple in the Altes Land (Lower Saxony and Hamburg) and Winter wheat in the Uckermark (Brandenburg), a system is being developed during the three-year project in cooperation with project partners and agricultural enterprises, that provides practical decision-making aids for short to long-term extreme weather management.
“An important component here is the development of suitable communication channels”, says Dr. Detlef Deumlich, agricultural engineer at ZALF. “Therefore, in addition to an Internet platform, an app for mobile devices is also being developed to support farmers and fruit growers with their daily decisions.”

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
Sizes and shapes of nuclei with more than 100 protons were so far experimentally inaccessible. Laser spectroscopy is an established technique in measuring fundamental properties of exotic atoms and their nuclei. For the first time, this technique was now extended to precisely measure the optical excitation of atomic levels in the atomic shell of three isotopes of the heavy element nobelium, which contain 102 protons in their nuclei and do not occur naturally. This was reported by an international team lead by scientists from GSI Helmholtzzentrum für Schwerionenforschung.
Nuclei of heavy elements can be produced at minute quantities of a few atoms per second in fusion reactions using powerful particle accelerators. The obtained...
