Farming Systems Ecology Group

1. Farming Systems Ecology Group

2. Vision: To be an internationally leading player in the fields of research and education that,
Farming Systems Ecology
through a farming systems approach, contributes alternative answers to the major problems
facing current agriculture, namely:
(i) global food security;
(ii) provision of ecological services;
(iii) food and environmental health;
(iv) adaptation to climate change;
(v) preservation of the biological and cultural diversity of agricultural landscapes.

31. FSE: Systems approaches to ecological intensification
Five guiding heuristics
1. Ecological intensification must be precised in terms of how
much, where and how
2. Farming systems research (analysis) is not the same as
farming systems design (synthesis)
3. Agroecological innovation can draw inspiration from nature
and from local knowledge systems
4. Ecological intensification depends on patterns-functions
operating at the landscape level
5. Moving across scales implies meeting trade-offs concerning
resource allocation decisions
