Catastrophic shifts in drylands: how can
we prevent ecosystem degradation?
Introduction of the CASCADE project
Coordination: Prof. Coen Ritsema
3. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
One of the most challenging themes in ecology over the last decades is the quest
for the understanding of critical transitions (tipping points) in ecosystems…
CASCADE focuses on critical transitions in dryland ecosystems
Such shifts in drylands may imply major losses of biological diversity,
ecosystem functioning, and provision of ecosystem services
4. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Critical transitions can be explained by linkages among
Vegetation structure Availability of
(species composition, resources
cover) (water, nutrients)
Biotic and abiotic
disturbances
Empirical evidence??

CASCADE combines manipulative experiments, models, and
field assessment to investigate catastrophic shifts
Objectives
- Better understanding of sudden shifts in drylands that may lead to major losses
in biodiversity and ecosystem services.
- Improve our understanding of the mechanisms underlying sudden and catastrophic
shifts, and of the key biotic and abiotic factors influencing these processes.
- Develop ways to predict the proximity of dryland ecosystems to tipping points in such
a way that these predictions can be used by policymakers and land users for more
sustainable management of drylands worldwide.

CASCADE investigates dryland ecosystems in southern Europe :
6 study sites in the Mediterranean region
Fire recurrence
Past overexploitation (grazing, wood gathering, ..)
Land abandonment; grazing mismanagement
Overgrazing
7. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Analyse the historical and current state of selected dryland ecosystems in
relation to climate and human activities, and the role of tipping points in their
degradation processes (WP2)
8. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Unravel regulating processes in plant-soil system dynamics and
tipping points (WP3)
9. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Assess on a field mesocosm scale the interplay between vegetation
structures (spatial patterns and composition) , resource redistribution
and sudden regime shifts (WP4)
10. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
Assess on a landscape scale the changes in vegetation structure (composition,
cover, spatial patterns) and ecosystem services associated to regime shifts, as
well as the potential of restoration of degraded systems (WP5)
11. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Develop a spatially explicit model that links the empirical observations on
the various scales in WP3, WP4 and WP5 to come up with empirically
based indicators of the proximity of the ecosystems to tipping points(WP6)
12. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Design management strategies to deal with tipping points in dryland ecosystems;
comprehensive guidelines including principles, best practices, implementation
approaches and recommendations (WP7)
13. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
- Integrate socio-economic factors into the ecological model and undertake
scenario analyses of land management strategies, to enable formulation of
policy recommendations for dryland management (WP8)
14. UNCCD 2nd Scientific Conference 2013 -- Bonn
UNCCD 2nd Scientific Conference 2013 Bonn
Specific Objectives
Make the results accessible to the scientific community focused on the outcomes
of the integrated modelling, indicators of sudden shifts, and adaptation strategies,
and develop a multi-media communication strategy on knowledge transfer and
dissemination (WP9)

Major expected impacts of CASCADE:
Knowledge impact. Advancement of knowledge on dryland ecosystem functioning
with regard to tipping points and sudden anthropogenic or climate induced shifts.
Community impact. Development of land use and management measures aimed
at preventing catastrophic shifts of ecosystems and preserving ecosystem
functions and services for the populations living in European drylands.
Policy impact. Feeding knowledge and recommendations to policy makers
at the regional, national and international level
