Hannes Schritt

MSc (Environmental Engineering)



Hannes Schritt is a Researcher for Ecologic Institute and works mainly in the fields of ecosystems, nutrient cycles and agriculture. His research activities include plastics in the environment, circular economy, water management, evaluation of regulations in agriculture and their impact on ecosystems and climate change adaptation. Hannes Schritt works in German and English, is conversational in Spanish and has basic knowledge of Portuguese and French.

For Ecologic Institute, he works mainly in the project PlastikNet on plastic in the environment – sources, sinks, solutions and in the project WADKlim on adaptation to drought in Germany. He advises the European Environment Agency on issues related to the continuity of European rivers and the establishment of monitoring systems for air pollutants. Recently he evaluated agricultural consultancy systems in Schleswig-Holstein and North-Rhein Westphalia and their impact on ecosystems.

Plastics in the Environment – scientific coordination & transdisciplinary knowledge network (PlastikNet): This four-year project funded by the German Federal Ministry of Education and Research (BMBF) aims at supporting the political and societal impact of the funded research projects, most of which focus on microplastics in the hydrologic cycle. Hannes Schritt works here primarily in the fields of analytics, ecotoxicology and modeling.

The WADKlim project is investigating the impacts of climate change on water availability, particularly with respect to groundwater recharge and groundwater availability during drought, criteria for dealing with water use conflicts, and water reuse in metropolitan areas. Hannes Schritt will work mainly on the last two topics.

Before arriving at Ecologic Institute, Hannes Schritt contributed to work on the climate mitigation concept EKaKorn at the company Kornkraft Naturkost GmbH in cooperation with Jülich Project Management. Prior to studying, he worked as a human rights observer in Chiapas (Mexico).

Hannes Schritt received his Master's degree in environmental engineering at the Technische Universität Berlin (Germany). His thesis focused on innovative approaches to closing nutrient cycles in the agroecosystem of an indigenous community in the Amazon. He presented the results of his thesis to local farmers in Sarayaku (Ecuador) in the form of comics and integrated his concept in school teaching. In 2013, he spent a semester abroad at the Universidade de Pernambuco in Recife (Brasil).
