Day of Insects brings together dedicated people from all over Germany

On 21st and 22nd March 2018 Insect Respect and the partner organizations hosted for the second time the nationwide Day of Insects in Bielefeld.

About 150 participants from economy, science, environmental organizations, the media and civil society presented their projects and activities concerning the promotion of insects in speeches and at networking tables. In action forums they discussed how to establisch intersectoral round tables for biodiversity all over Germany, how to enthuse more volunteers with natural research and conservation and how topics such as biodiversity and insects can increasingly find their way into the headlines of the media. The open, moderated panel discussion made clear that cooperations can succeed if all parties are open for unconventional solutions.

„The goal of this conference is to motivate as many people as possible to rethink“, said the conference director Dr. Hans-Dietrich Reckhaus, CEO of Reckhaus GmbH & Co. KG and inventor of Insect Respect. „Together we are the insect lobby.“ On the 21st March 2018 he opened new insect-friendly habitats as a tangible measure on his company’s grounds in Bielefeld: on ground level, vertically at buildings and on roof areas. „Every square meter counts“, emphasized Philipp Unterweger, biologist at Insect Respect, during the public tour.

Josef Tumbrinck, North Rhine-Westphalia’s chairman of the Nature and Biodiversity Conservation Union (NABU), showed in his speech on the 22nd March 2018 that insect depletion reached the populace and politics — right up to the federal coalition agreement — but that it must not lack professional depth: „Not only insects are dying out, entomologists are dying out as well.“ More expertise at universities and in practical economy is necessary.

„Very often, companies cannot relate their business to biodiversity“, said co-organizer Stefan Hörmann, leader of „companies and biodiversity“ at the Global Nature Fund. He explained, how the Biodiversity Check can help to embed the topic strategically and long-term. Dr. Katrin Reuter from the 'Biodiversity in Good Company' initiative emphasized that NGOs play a vital part in establishing biodiversity aspects in economy.

„Insects, as pollinators, are a central part of our ecosystems and provide the foundation of food production. Their habitat has to be protected and their food availability has to be supported“, said Dr. Florian Schäfer from REWE Group. In the final fishbowl discussion he made clear why the trade company is involved in the PRO PLANET apple project: „The biggest added value is the cooperation between agriculture and nature conservation.“ The dialogue fosters development and understanding on both sides.

On the 21st March 2018 midge expert Dr. Doreen Walther asked for understanding as well in her public evening lecture: „If you want to understand midges, you have to think like a midge.“ The animals are attracted by standing water but also by the CO2 from breathing air, by smells and high-contrast clothing. Prevention and caution should be expected from human reason because „every control measure harms the equilibrium.“

The presentations, videos, photos and texts will soon be published in a publicly available multimedia conference documentation on the Insect Respect website.

Co-organizers were Insect Respect (company Reckhaus), the Global Nature Fund and the Natural History Museum Bielefeld; the REWE Group supported the conference.

Exchange of experiences & dialogue

In order to stop insects dying a lot of commitment from many sites will be necessary. Politics, economy, non-profit organisations, civil society and the public need to contribute. To ensure the stakeholders open themselves to an exchange, Insect Respect and partners will host further such conferences.
The Day of Insects targets to show acitivites and to promote the network of all interested players – in the short and long-term perspective.

    "As pollinators insects are a central component of our ecosystem and form the essential basis for food production. Their habitats need to be protected and their food supply promoted”, says Dr. Florian Schäfer, REWE Group. As early as 2009, the trading company together with the Bodensee Foundation and the sales company “Obst vom Bodensee” launched a pilot project to promote insect protection in fruit cultivation. In cooperation with the Lake Constance Foundation, Birdlife International Austria and NABU, the first PRO PLANET project has been started in 2010, in which 13 growing regions and 250 fruit growers promote biodiversity in apple cultivation. For the REWE Group, cooperation with a lot of stakeholders is an important success factor. For this reason, the trading company participates in the Day of the Insects in order to strengthen the dialogue between research, companies and civil society organisations and to enable cooperation between different stakeholders.
