School of Earth and Environment INSTITUTE FOR CLIMATE AND ATMOSPHERIC SCIENCE Dr. Nicola Favretto n.favretto@leeds.ac.uk Multi-Criteria Decision Analysis Workshop on the Economics of Land Degradation (ELD) Sustainable Land Management in Kgalagadi Rangelands 08 th July, 2014
2
Introduction Outline the socio-economic dimensions of land use and link them to the environmental findings through Multi-Criteria Decision Analysis (MCDA) Research objective “To identify the ES benefits provided by each land use, and discuss the costs and trade-offs associated with their delivery under different land uses and management” Aim of MCDA To rank alternative land use options by quantifying, scoring and weighting a range of quantitative and qualitative criteria
3
Four step process of MCDA I 1.Problem definition & identification of options “Which land uses and land management strategies are best placed to deliver specific ES in Kalahari rangelands in Botswana's southern Kgalagadi district?”
4
Four step process of MCDA II 2.Criteria definition & assessment
5
Four step process of MCDA III 3.Criteria weighting (using policy analysis) Reflect the criteria relative importance for policy-making 4.Derivation of each option's overall preference score Each criterion scored on a 100-point scale (0=less important, 100=most important). Overall score = criteria score * weights
6
Results I - Criteria performance
7
Results II – Final scoring
8
Results III Weighted performance of the four alternative land uses

Conclusions I Cattle production provides the largest financial benefits to private land users, but generates broad negative environmental externalities: Retreat of grass cover and bush encroachment Reduced access to ES other than commercial food Decrease in livestock income Fencing & support provided to borehole drilling for ground water extraction: concentration of cattle around water points
10
Conclusions II Livestock encroachment, rangeland degradation & obstructed wildlife mobility declining wildlife numbers in & next to Wildlife Management Areas Decreased economic viability of Community- Based Natural Resource Management and ecotourism activities
11
Conclusions III Livelihood diversification opportunities to the poorest (partly dependent on subsistence hunting and gathering) are limited There is a need to: Assess/establish potential markets for provisioning ES Limit borehole development within communal areas in proximity to Wildlife Management Areas Trading of carbon credits? Further methodological development needed (monitoring, reporting & verification)
12
Conclusions IV In establishing Sustainable Land Management practices, trade-offs between profitability, social distribution of wealth, cultural values and land degradation must be considered across (as well as within) land uses
