Our Projects
Working Together for Sustainable Impact

At Lehmann Natur, we regularly participate in national and international projects to help shape the future of organic farming in a sustainable way. Through close collaboration with research institutions and partners across the entire value chain, we contribute our practical experience while supporting the development of innovative, scientifically sound solutions. In this way, we ensure that our commitment to responsible sourcing and organic farming extends beyond our own activities and achieves positive long-term effects.


Our project “Organic Limes from Colombia” is a joint initiative with a smallholder cooperative that integrates ecological, social, and economic aspects. Together with our local partner, we have significantly increased the number of participating farms over the past few years and are creating long-term prospects for the farmers by guaranteeing reliable purchasing. At the same time, we promote sustainable cultivation methods and certifications – such as Organic, Fairtrade, and Demeter – to enhance quality and value creation. In this way, we help secure stable incomes and foster sustainable growth in production through to 2027.

Currently, organic farmers are still permitted to use conventional, untreated seed if sufficient organic seed is unavailable. This exemption expires in 2037. If there is insufficient organic seed by then, significant supply shortages for organic products could arise. The ROADMAPS project, led by the Research Institute of Organic Agriculture (FiBL), therefore develops strategies to improve the supply of organically produced seeds and plant material. We support the project by discussing seed quality with our producers and determining how this information can be integrated into our ERP-system.
