Dr. Christian Nawroth, Leibniz Institute for Farm Animal Biology (Germany)

I am interested in how animals perceive and interact with their physical and social environment. My research focuses on the cognitive capacities of livestock (goats, horses, pigs, sheep) and zoo animals (great apes, penguins) and how this knowledge can ultimately be used to improve management conditions and human-animal interactions.

Jean-Paul Dubeuf, INRA, Laboratoire de Recherches sur le Développement de l’Elevage (France)

Jean-Paul DUBEUF is a researcher (“Ingénieur de Recherches”) at the French National Institute in Agricultural Research (INRA) in “Science for Action and Development”, in Corte (Corsica).

For more than twenty five years, he has been specialized in the development processes of Small Ruminant with a special focus on the Mediterranean Area. His recent works have included Social, Environmental issues and Societal changes in the sustainable Development of the SR production systems and pastoralism and considered Ecological Transitions issues. In this context, he is studying presently more specifically the implementation of public policies for these activities in several projects at International (with IFAD), National (in Morocco) and Regional (in Corsica) levels.  He has published several applied research articles, review articles and position papers on these themes. He is also exploring at what extent, pastoralism could be an alternative to the present crisis of Animal Production to redesign innovative production systems answering these challenges.

Jean-Paul Dubeuf has also developed an expertise on the conception and development of an Information System on line for the animal production sectors (data basis, documentation, workflow, synthetic analysis) as the Scientific Director of the International Resource Center on Sheep and Goats Dairy sectors (CIRVAL) from 1995 to 20007.  

He animated and coordinated several Mediterranean scientific sub networks (FAO/CIHEAM, International Dairy Federation) and cooperative international projects. He was President of the International Goat Association from 2008 to 2012.

During 10 years from 1984 to 1994, he was an Expert and Consultant to support decision making activities and extension in the dairy co – operatives sector in Central France for the Technical Bureau in Dairy Promotion (BTPL).
