Water for Forests and People in the Mediterranean Region -

Foreword: Based on presentations at the Second Mediterranean Forest Week in Avignon (April 2011), the present article aims at briefly highlighting a few topics drawn from the book: "Water for forest and people in the Mediterranean Region"

Social network analysis as a tool for the analysis of international trade of wood and non-wood forest products

Countries are almost exclusively seen as the primary unit of analysis in the study of international trade; and analysis of trade in wood and non-wood forest products is no exception to that rule. This paper uses the relationship among countries as the primary unit of analysis and introduces different procedures of social network analysis, where the goal is to demonstrate their applicability to the study of international trade of forest products. Compared to statistical analysis, additional benefit of social network analysis is the fact that the assumption of independence of observations does not hold true; and thus enables a more thorough insight into the structure of the international trade network. Data on international trade of chemical wood pulp, truffles, and aggregate forest products in the 1988\u20132006 period is used to demonstrate the applicability of selected network indices as descriptors of economic flows among countries. The analysis covers topics of network visualization, characteristics of the network, grouping of countries, their individual positions and modelling of international trade that includes endogenous effects such as reciprocity, and exogenous effects such as forest certification and contribution of forestry to the gross domestic product. Results show that many procedures of social network analysis can be used in the field of international trade of forest products, but that great care is needed in their contextual interpretation. Prominent topics of application are the structural trends and impact of different policies, such as the EU Timber Regulation on international trade of wood-based products

Assessing impacts of intensified biomass production and biodiversity protection on ecosystem services provided by European forests

To develop viable strategies for intensifying the use of forest biomass and for increasing forest protection, impacts on ecosystem services need to be assessed. We investigated the biophysical and economic impacts of increased forest biomass production and biodiversity protection on forest ecosystem services. The European Forest Information SCENario (EFISCEN) model was applied for 26 European countries. Three different scenarios were considered: a reference scenario (no policy changes, a moderate increase in roundwood, residue and stump biomass production), a wood energy scenario (enhanced roundwood, residue and stump biomass production to achieve national renewable energy targets), and a biodiversity scenario (setting aside 5% of the forest area with restrictions on wood production combined with biodiversity-friendly management on the remaining area). The impacts were assessed by analyzing impacts on provisioning (roundwood production and residue and stump biomass production) and other services (carbon storage, deadwood and recreation) for the period 2010–2030. We found that roundwood, residue and stump biomass production could be intensified, but there are trade-offs with non-marketed ecosystem services. Increasing biomass production could lead to a net societal benefit in 2030. However, larger benefits would be obtained within Europe if forest biodiversity protection is enhanced
