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

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. „
