overall reduction in biodiversity, possible alternative stable states of an ecosystem notwithstanding. Ecological effects of biodiversity are usually counteracted by its loss. Reduced biodiversity in particular leads to reduced ecosystem services and eventually poses an immediate danger for food security, also for humankind.
observation led to the question of how such loss of biological diversity will alter the functioning of ecosystems and their ability to provide society with the goods and services needed to prosper. In the past 20years remarkable progress has been made towards understanding how the loss of biodiversity affects the functioning.
Loss of Biodiversity Impacts Human Health. Brussels/Montreal, 4 June 2015 – Healthy communities rely on well-functioning ecosystems. They provide clean air, fresh water, medicines and food security. They also limit disease and stabilize the climate. But biodiversity loss is happening at unprecedented rates, impacting
to understand the consequences of loss of biodiversity for the functioning of ecosystems (Daily et al. 1997,. Heip et al. 1998, Chapin et al. 2000). Although the view that species richness is beneficial for ecosystem performance is widely endorsed (Tilman et al. 1996,. Naeem et al. 1999), it is not accepted universally (Gi-.

11 May 2000 extent to which this loss of biodiversity matters; that is, are stability, productivity and other aspects of the functioning of both managed and natural ecosystems dependent on biodiversity? There are strong reasons to hypothesize, as did Darwin2 and Elton3, that biodiversity might impact ecosystem processes.

It entails five axes: (a) Demographic change: although from a theoretical point of view the relation between population pressure and the impact on
