1. UNCCD 2nd Scientific Conference, 9-12 April 2013, Bonn, Germany
Towards improved decision-making
in degraded drylands of southern Africa:
an indicator based assessment for integrated evaluation
of restoration and management actions in the Kalahari rangelands
N. Dreber, T.M. Kong, K. Kellner, A. van Eeden, A. Ocampo-Melgar

2. INTRODUCTION UNCCD 2nd Scientific Conference 2013
STUDY SITE
The Kalahari case study
in the Mier area
• arid, SW-Kalahari basin
• livestock farming & game ranching
• small-holding to semi-commercial systems

3. Kalahari rangelands
Unpredictable climate,
little farm infrastructure,
inadequate water
availability, inflexibility in
employing SLM resulted in
widespread degradation of
south-western Kalahari
rangelands
Degradation severely affected
biodiversity and provisioning of
essential ecosystem services
Local attempts to mitigate degradation should
actively involve land-user at all levels of project
planning, decision-making and execution
Van Rooyen 1998, J Arid Env

INDICATOR WEIGHTING
Relative importance of indicators
iteration process with social learning effect
Pack-of-Cards Method:
1. Ranking indicators as independent thinkers
2. Computation of collective weights
3. Re-ranking following group discussions and
comparison with calculated collective weights

INDICATOR WEIGHTING
Indicator weighting: how important for the evaluation of actions?
Rank-shift: Indicator 1st 2nd
Biodiversity: 11 5 Water availability 1 1
Grazing capacity: 8 3 Animal condition 4 2
Grass abundance: 3 8 Grazing capacity 8 3
Personal well-being 2 4
Biodiversity 11 5
Soil condition 5 6
Biomass production 6 7
Abundance grasses 3 8
Economic costs 7 9
Change in perception/ social learning effect Abundance woodies 10 10

21. IAPro Step 1-6 UNCCD 2nd Scientific Conference 2013
CONCLUSIONS
IAPro Step 1-6:
Conclusions & lessons learned
Generals:
(1) IAPro is a promising framework for evaluating restoration and management actions
(2) IAPro offers insights into the wealth of site-specific indicators
(3) IAPro allows for a locally-contextualized assessment and evaluation process
Indicators refer to local-scale needs, represent key ecosystem services and
address both ecological and socio-economic issues
Social learning & acceptance:
(1) The participatory environment furthers a more diversified understanding
(2) The exchange among stakeholders creates opportunities for co-operative actions for the
benefit of the local farming community
Being better informed allow to adapt more effectively, being part of the
evaluation process increases acceptance of results

22. IAPro Step 1-6 UNCCD 2nd Scientific Conference 2013
CONCLUSIONS
IAPro Step 1-6:
Conclusions & lessons learned
Challenges:
(1) Location: huge distances may result in low participation rates at critical participatory steps
(2) Temporal environmental heterogeneity: remote location + distances + time- & budget-
constraints hampers timing and frequency of data collection
(3) Spatial environmental heterogeneity: preferential sampling approach used for indicator
quantification may hamper the identification of suitable replicate sites
Project implementation and proper application depend on e.g. a stronger
collaboration between Universities, local institutions and government (compromises
might not be sufficient/ fall too short)

23. IAPro Step 1-6 UNCCD 2nd Scientific Conference 2013
CONCLUSIONS
IAPro Step 1-6:
Conclusions & lessons learned
Challenges:
(1) Environmental awareness and implications differ depending on the socio-economic
setting and farming objectives (e.g. commercial vs. communal ranching, farming with
grazer vs. browser)
(2) Applicability: lack of regulating local-level institutions, inappropriate governance
structures and legal policy frameworks influence and constraint restoration actions and
land management strategies
Need for a land-use / -tenure stratification for improved local contextualization

24. IAPro Step 1-6 UNCCD 2nd Scientific Conference 2013
CONCLUSIONS
IAPro Step 1-6:
Conclusions & lessons learned
Way forward:
(1) Testing the approach’s flexibility in coping with different social, economic and
environmental contexts of the Kalahari
(2) Coupling the assessment approach with local-level institutional mechanisms and
structures adapted to the different land-tenure forms
(3) Assure implementation, monitoring and long-term guidance backed by governmental
help
