Muthurajawela Marsh, Sri Lanka a WANI case study (Emerton et al. , 2003) • Largest saline coastal peat bog in Sri Lanka • 300, 000+ people living around the marsh • 80% of industries of Colombo and Gampaha dist. • Negombo lagoon – fisheries productivity of 150 kg/ha/year • Wetland Sanctuary (~58%) WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Muthurajawela Marsh, Sri Lanka a WANI case study (Emerton et al. , 2003) • Economic benefits of just over $2, 600/hectare/year for the whole of the Marsh • Non consumptive use benefits of $4. 4 million for the Wetland Sanctuary: – buffers floodwaters before they reach the lagoon during rainy season – receives and retains high loads of domestic and industrial wastes as well as sediments and silt loads from both surrounding and upstream areas WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Muthurajawela Marsh, Sri Lanka a WANI case study (Emerton et al. , 2003) • Findings: – High economic benefits from wetland restoration – real economic losses to local households from any reduction in extractive wetlands activities • Recommendations: – Package of economic incentive measures, including income generating activities – Penalties for wetland damage through infrastructural and industrial expansion WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Case studies and methods in IUCN publications • VALUE : counting ecosystems as water infrastructure: (English, Spanish, Chinese) • Economic valuation of ecological functions and services of natural ecosystems : A Guide on the use of simple methods (French, English) WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Sourou Valley, Burkina Faso a TEEB case study (Somda & al. , 2010) • 2009 Economic Valuation, ecosystem services considered: – Crops, livestock, fish, wild foods (non-timber forest products), fuelwood, provision of water for transport (provisioning services) – Tourism (cultural services) – Groundwater recharge and discharge (regulating services) – Biodiversity and habitat (supporting services) WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Sourou Valley, Burkina Faso a TEEB case study (Somda & al. , 2010) • 2009 Economic Valuation, valuation techniques considered: – Market prices for value of fuelwood, fish, transport, non-timber products, fodder for livestock production and tourism. – Valuing effect of wetlands on crop production estimated through examining differences in fertilizer use for farms near river and farms 10 km from it. – Qualitative analysis and focus group discussions to collect data for regulating and supporting services.

Sourou Valley, Burkina Faso a TEEB case study (Somda & al. , 2010) • Main findings: – annual (minimum) value about US$ 21. 2 million for a population of 62, 224 – Crop production not the region’s major economic good despite significant past investments WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Sourou Valley, Burkina Faso a TEEB case study (Somda & al. , 2010) • Challenges: – Substantial secondary data on provisioning services required to integrate variability of services – Other economic valuation techniques (e. g. contingent valuation) to estimate non-market services require preparing informants well to avoid free-riding effects – Resources for more comprehensive assessments, including country-wide, as part of economic development strategies and plans WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Sourou Valley, Burkina Faso a TEEB case study (Somda & al. , 2010) • Lessons for political uptake: – Guidance for local decision-makers to allocate resources – Include in early stages of land use planning – Insights into the political choices for the development of the area as well as other similar areas in Burkina Faso and in West and Central Africa. • Critical factors for upscaling: – Stakeholder involvement – Partnership development – Raising awareness ------> WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Benefit transfer methodology for freshwater ecosystem services • Burkina Faso and Mali (Sourou Valley) • Basse Casamance (Senegal) and Natural Mangrove Park of Cacheu (Guinea Bissau): – Agriculture production (soil): ~ US$ 2. 75 million – Hunting: ~ US$ 3. 22 million – Handicraft: ~ US$ 0. 65 million – Navigation: ~ US$ 0. 27 million – Other non-consumptive uses (carbon sequestration and water quality control): ~ US$ 11. 6 million WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
Looking ahead: upcoming IUCN activities on economic valuation • Using these approaches in decision making: • Valuation alongside modelling and analysis of tradeoffs, and action learning with decision makers • applying economic valuation in a more local-level, integrated planning and inclusive green growth strategies in the Ihemi-Kilombero cluster of Tanzania’s Southern Agriculture Growth Corridor (a collaboration between AWF, IUCN, and KILORWEMP) WATER ECONOMIC VALUATION OF FRESHWATER ECOSYSTEMS SERVICES IWC 8
