Introduction
SP08 within TFO follows the conceptual framework of TFO in
� delivering valuations as input for stakeholder communication
� translating ESS in user perspective and asking for
SP08 has worked on
� Willingness to Pay of Tourists in Seronga
� Social-Metabolism in Seronga
� Farming System Analysis and Shadow Prices in Mashare
� Scenario-building & Multi-Criteria Analysis in Seronga
SP08 will work on
� Payment for Ecosystem Service in Chitembo and Seronga
� Farming System and Shadow price in Chitembo
� Making Contribution to overall TFO goals
SP08 in valuation• scarcity of ESS for raising awareness
• ecological valuation of land use opt-
tions (MEFA, ecological integrity)
• shadow pricing (SPA) of ES services
• Willingness to pay (WTP) for ESS
• Multi Criteria Analysis (MCA)
• PES Stakeholder evaluation of
scenarios abd scenario building (ESB)

An Analysis of Tourist Preferences for
Ecotourism in the Okavango Delta� For a choice experiment we have
developed hypothetical scenarios
using the below attribute
- landscape- flooded delta
and reduced water flow
- wildlife- less chances of seeing wildlife due population
reduction
- management of community tourism enterprises- joint
venture with privately owned enterprises
� Levels of these attributes have been grouped into choice sets
to estimate marginal willingness to pay of tourist

Reasons for visiting Okavango Delta
• Tourists prefer the flooded delta and seeing many wildlife species
even at increased prices
• 54% of tourists are willing to contribute to compensation fund to be
established by the government
• 73% of tourists are willing to pay more to involve the community in
ecotourism activities

tool
Data collection
� For MEFA
� surveys on HH-level up-scaled on village level;
� secondary literature
� For the Useful Energy Analysis
� Focus groups on food consumption and on labour;
� HH estimations up-scaled on village level
Useful Energy Analysis
Energy efficiency of energy used for production
� Final Energy = food consumption
� Useful Energy = labour

method
Valuation via Shadow Price detection
Bio-economic modelling: � based on thorough Farming System Analysis � appropriate simplification
Shadow prices derived for:� Soil Quality: Yield and SQ assessment in 2013
� Irrigation water: extremely thin data base, as most commercial irrigation projects did not document any production data
Modeling of households‘ decision making: � Maximize Utility by allocating a typical households labour between agricultural
practices and casual wage work; other activites assumed constant.
Adaptation to three core sites. � Example Mashare, Namibia: Household categorization into:
ox-owners (34 % of HHs) vs. non-ox-owners (66% of HHs)
� Land scarcity in Namibia vs. land abundance in Angola
results
Preliminary Results for Mashare (Namibia)
• Minor diversification of crop production: 91.4 % of all farm-
households cultivate not more than three crops (i.e. usually 2–4),
• Mahango plus at least one vegetable (81.2%) and at least one fruit 68.2
(68.2%).
• Smallholder subsistence agriculture on 2 – 4 ha with is the main livelihood activity for the vast majority of local households.
• 88 % of all households practices dryland cropping with pearl millet (Mahango) (Pennisetum glaucum) as the main crop
• 75 % of all households own herds of less than 20 cattle and/or goats, mainly for subsistence reasons (TFO 2011)
• Extremely low yields of on average 161.2 kg/ha

„I think stories are very important things so that we
will start to preparing ourselves to know what to do
and what not to do. I think it is very important for us as
a generation, within the country, nationally,
internationally. „
