Environmental Effects of Afforestation in North-Western Europe; 2007, p1-18, 18p |
| Abstrakt: |
The current landscapes in north-western Europe are the result of natural processes and human-induced land use and land use changes. Whereas during past centuries, the natural ancient forest cover disappeared and was -sometimes abruptly- converted in intensively used cultural landscapes, an opposed trend has become apparent recently. This trend reversal is at least partly related to the decision of the European Union and several of its member states to actively promote afforestation of -mainly- farmland, in order to respond to surplus agricultural production and to contribute to the international efforts to reduce the nitrate pollution of water bodies and the emission of greenhouse gases. However, many questions pertain regarding the implementation and evaluation of environmental effectiveness and efficiency of this afforestation policy. The ultimate goal of this book is to assist stakeholders, such as forest and landscape planners and policy makers, in scheming and planning new forests in an environmentally sound way with as many positive and as few negative effects on the environment as possible. The book focuses on the influence of afforestation on carbon sequestration, nitrogen deposition, nitrate leaching, water recharge and potential biodiversity. It deals specifically with the ex-ante evaluation of afforestation measures based on i) field analyses in chronosequences of forest stands planted on former arable land, ii) modelling of these systems using mechanistic models describing the water, C- and N-cycles as well as the understory, iii) simplification of the process-based models into a metamodel (METAFORE) and iv) integration of data and models in a computerized spatial decision support system (the AFFOREST-sDSS).
