The diversity of life is valuable: it guarantees people goods and services such as clean water, food and raw materials. Biodiversity is the basis for health and a stable environment. Diverse habitats mean secure yields in agriculture, mitigate the effects of climate change and increase the attractiveness of locations. One of the key challenges is to reconcile the goals of national and international biodiversity agreements with the often competing objectives of climate, energy, agricultural and economic policy. The Leibniz Research Network Biodiversity combines the expertise of Leibniz institutions in the environmental, social, life, spatial and economic sciences to develop sustainable solutions.
