Ecosystem Health and Sustainable Agriculture Warzaw December 4 -5, 2008 One World, One Health Prof Ulf Magnusson Department of Clinical Sciences Faculty of Veterinary Medicine and Animal Sciences ulf.magnusson@kv.slu.se

From the global fight against the avian influenza..... ulf.magnusson@kv.slu.se

Infectious diseases are becoming more Global Causes: More travelling More trade – animals and animal products Climate Change ulf.magnusson@kv.slu.se

The human – domestic animal (agriculture) – wildlife (ecosystem) interface Zoonoses ulf.magnusson@kv.slu.se

The importance of zoonoses and this interface (I) Jones et al. 2008. Nature,451:990- ulf.magnusson@kv.slu.se

Examples of zoonotic infections moving between domestic and wildlife to humans….. Tuberculosis Cattle Deer Badgers Pasteurisation In Europe ulf.magnusson@kv.slu.se

Giardiasis Water borne Intestinal In Europe ulf.magnusson@kv.slu.se

Brucella melitensis Mainly sheep and goat Also small wild ruminants Occupational health hazard Also cheese and milk if not pasteurised Ongoing outbreak in Bosnia , very parhogenic ulf.magnusson@kv.slu.se

Nipah virus Malaysia Fruit bats and pigs 1998-1999, 100 persons died, 1 million pigs killed, respiratory disease Habitat destruction or pig farms in “wrong” places suspected… ulf.magnusson@kv.slu.se

So what about health and sustainable agriculture ? One have to consider: Biodiversity - in the surrounding environment - at the farm Biosecurity Production economy and risks Lots of conflicting interest ulf.magnusson@kv.slu.se

Biodiversity in the environment and infectious diseases High biodiversity in wildlife generally good (serves as a buffer) Also low density of animals Also large habitats ulf.magnusson@kv.slu.se

“Biodiversity” at the farm and infections Generally regarded as a risk to mix or keep several species closely together However, in another way the farm as a whole more vulnerable if just one species Mixed messages! Biosecurity – Production Economy ulf.magnusson@kv.slu.se

Biosecurity and farming systems It is easier to keep a high biosecurity if there is: One species at the farm Small units Confined units ulf.magnusson@kv.slu.se
