Cross-cutting activities and alliances

The Helmholtz Earth and Environment research field has initiated numerous cross-cutting activities and alliances in order to draw different research areas together, promote key profile-building topics, and develop networks with other scientific partners in Germany.

For example, in the Helmholtz Climate Initiative, which spans the whole of the Helmholtz Association, 15 Centers from all six research fields are focusing on the two priorities of Net-Zero 2050 (mitigation) and Adaptation to Extreme Events (adaptation). In the mitigation cluster, we aim to prepare scientific contributions toward a road map that will outline how Germany can reduce its CO2 emissions to net zero by 2050 and how we can actively remove CO2 from the atmosphere. In the adaptation cluster, our objective is to identify adaptation options in many areas of life, such as health, agriculture, energy supply, and transport. Nine of our Centers are also contributing their expertise as part of the Helmholtz Regional Climate Change Network (REKLIM) in order to develop Earth system models that take account of the interactions between the atmosphere, ocean, cryosphere, biosphere, land surfaces, and soils. These models make it possible to analyze regional changes in the climate in the past, present, and future more precisely. The models are sought-after, for instance, by decision makers in need of a sound scientific basis for their political and socioeconomic actions. A further important task of REKLIM is to take this knowledge from the field of climate research into the public domain. For example, this includes – the information and data portal concerning sea ice – the Drought Monitor for the whole of Germany, and the German Regional Climate Atlas. Some of our Helmholtz Centers are collaborating in nine further cross-cutting activities, where they are investigating subjects such as remote sensing, geoenergy, bioeconomy, and the issue of resilient urban areas.

The cross-topic cooperation of scientists in the Helmholtz Earth and Environment research field also takes many forms. In one example, we use flexible and mobile Earth observation measuring systems (MOSES) to investigate how extreme events influence the long-term development of Earth systems and environmental systems. This work helps us to provide answers to burning questions: What impact do heat waves have on the water supply, vegetation, and air quality? How do floods change terrestrial ecosystems and coastal zones? How do ocean eddies influence energy distribution and food chains in the oceans?

In further interdisciplinary Helmholtz collaborations, we focus on environmental monitoring and the effects of changes in the climate and in land use on terrestrial environmental systems (TERENO), on Earth system modeling (ESM), and on linking up a range of data from atmospheric, ocean, and terrestrial research (Digital Earth).

The Earth and Environment DataHub has three decentralised Hubs (DATA, MARE, TERRA) that form an interconnected base structure and are also interlinked by well-defined working groups. The creation and sustainable operation of the DataHub as a FAIR-ready infrastructure provides data science in Earth and Environment a solid foundation for new insights.

We also cooperate with the Max Planck Society, the Leibniz Association, and numerous universities as part of the German Marine Research Alliance (DAM) and the German Earth System Alliance.
