1 Economic analysis of the forest investments for the production of the environmental services in Tunisia Amira Gammoudi (INRGREF) Supervisor: prof./dr. Hamed Hassen Daly AGORA - Adapting Mediterranean forests to climate change Workshop: New economic approaches to in forest goods and services marketing Fez (Morocco), September 2011

2 Introduction Many projects were established for the Tunisian forests. Public and private During the previous decade, these investments marked a real growth of more than 35% in relation to the year Previous analyses of forest investments in Tunisia have been focused on efficient wood production and land grazing. The assessment of major environmental effects is needed in economic planning.

3 Research objectives Get a bibliographic review of the instrument background Get a monetary assessment of market and non market goods and services offered by the forests in Jendouba. Analyze the costs of provision of the different market and non market forest goods and services Set up of a system of payment of environmental services (biodiversity, sequestration of carbon, recreation..). The revolution and the property right

4 Background Cesaro et al., 1998 used different approaches to estimate some benefits related to forestry and soil conservation projects in two watersheds Daly and Ben Mansoura, 2005 applied different valuation approaches to value several aspects Tunisian forests. Daly et al, 2010 applied Choice Modelling to value environmental benefits of forest based on the people preferences World Bank, Merlo M. et Croitoru L. (eds) Valuing Mediterranean forests. Towards Total Economic Value; CABI Publishing, Wallingford. Millennium Ecosystem Assessment (MEA) Ecosystems and human well-being.

8 Methodology To be able to design a PES in the Tunisian forests, the fundamental step is to assess the economic analysis of these forests. Valuation scenario: In our survey, we are going to perform a Cost Benefit Analysis to evaluate the benefits obtain from afforesting treeless land uses with cork oaks and Quercus canariensis, the Algerian Oak for infinite rotations. We apply this analysis for the forest investments realized in the region of Jendouba the last 20 years from 1990 (the year of foundation the Park of Elfeyja)

9 P/S WFP NWFP Cork Grazing Honey Valuation Method Market prices Market prices The substitute goods approach Market prices(beehivesi n forest Guariya in Fernana) Envirnomrntal sevices Recreation Biodiversity CVM (recreational value of Park Elfeyja and the importance of Elfayja park to protect and increase the number of the cerf de brebie ) Soil erosion Carbon sequestration Forest fires Damage Cost Avoided (measuring the cost of removing eroded sediment from downstream areas) Price of carbon on international markets. The Replacement Costs Method

10 Data Collection Derived from National reports and also the enterprises specialized on woods and fluel wood production. DGF: General direction of forest INS: National Institute of Statistics Questionnaire

11 Difficulties Non clear property rights and responsibilities for local communities and for Forest Administration. Too much restrictions for local populations Difficulty of identification and the quantification of the environmental profits and the shortage of data. The lack of given representative of the situation to the national and regional level. The lack of knowledge and capacity of application of the methodologies adapted to the economic valuation of the environmental profits and so the NWFP.

12 Conclusions (and recommendations) Formulate a concrete propositions concerning the revision of the tariffs of the products. TEV Develop new models of forest planning multiresources (including the non timber products and the non market services). Certification Tunisian forests after the revolution?
