1	Designing and Implementing Valuation Studies in the GCLME Region Preliminary Report on Economic Valuation of Ecosystem Services of GCLME
2	Outline of Presentation Estimates of the direct output value of goods and services for each of the relevant marine sectors of the 16 countries bordering the Guinea Current Large Marine Ecosystem (LME). Estimate the scale of resource rents that could be obtained from the economically optimal management of the marine resources of the case studies Work in progress on economic valuation of the GCLME
3	Functions and Attributes of GCLME to be Valued
4	Estimates of direct output value of goods and services of relevant marine sectors of GCLME Available methodology for estimation: Direct Output Impact (DOI)- Product of physical quantities of goods and services flowing from marine activities Total Economic Value (TEV): estimation of the net benefits from each nation’s marine activities and sums all the benefits across all activities
5	Approach Used and Relevant marine sectors of GCLM DOI (Prices in International Market were used) Fisheries, some NTFP and Mining activities. Tourism and Timber were considered although actual calculations were not done. Data sources: FAO data sets, World Bank (World Development Indicators 2004), US Department of the Interior (2005), Oil and Gas journal Data Book (2004) Nigeria Federal Department of Fisheries, Data collected through a questionnaire from some GCLME countries made available by Dr. Ajao In estimation of fish landing value for the GCLME countries, landings were aggregated for 1999-2003 and market prices were used
6	Value of Marine Fish Landing in GCLME
7	Value of Offshore Oil Production
8	Summary of Returns from Different Mining Activity
9	NTFPs Major NTFPs in the mangrove are Periwinkle, Rhizophora spp and Mudskipper Total amount realised from periwinkle= $1,941,273,740 (Shadow Prices - market data from Nigeria adjusted to reflect exchange rate fluctuations) Countries are Benin, Cameroon, Côte d’Ivoire, Equatorial Guinea, Gabon, Ghana, Nigeria, and Sao Tome and Principe
10	Summary of Value of Some Outputs from GCLME
11	Estimates of Resource Rent and Effect on Fish Resource Estimation was done using Lange (2003) estimation procedure which estimated resource rents as total revenues minus average cost assuming a normal profit of 30 percent as one element of average cost
12	Scale of resource rents without and with GEF funding
13	Work in Progress/Planned Activities Valuation of non-market ecological services as to obtain TEV assessing the social and economic costs of the nypa palm infestation on affected communities Developing a dynamic model of the biological growth of two competing coastal timber species, mangrove and nypa palm Setting-up a nonlinear program that seeks to optimize the relative shares of mangrove and nypa palm in the region providing estimates of the optimal distribution of species and the levels and time-paths of investment required to implement a policy that seeks to achieve the optimal distribution of species
