Afforestation management in north-western Europe - influence on nitrogen leaching, groundwater recharge, and carbon sequestration
  Login AFFOREST - Last update: 29th January, 2008

Untitled Document

The AFFOREST project investigated the impact of afforestation of former agricultural lands in north-western Europe on relevant environmental issues such as water recharge, leaching of nitrate, and carbon sequestration.

Our main goals have been:
  • to quantify the long-time influence of afforestation on nitrogen leaching, groundwater recharge, and carbon sequestration performing measurements in a series of chronosequence studies
  • to elaborate guidelines for the best possible afforestation of former agricultural lands to account for the environmental impact categories as mentioned
  • to guide and assist decision makers and foresters in their planning and design of new forests

The project ended in 2004. Important deliverables of the AFFOREST project are guidelines for afforestation and a spatial Decision Support System (AFFOREST-sDSS) to provide e.g., foresters, land use planners and policy makers with insight regarding the options and consequences of afforestation of the agricultural lands in their country.

New article (15-05-2007)

An article on nitrate leaching after afforestation has been printed in Global Change Biology 13, 1250–1264 (doi: 10.1111/j.1365-2486.2007.01355.x)

Book on the total AFFOREST project is out! (22-02-2007)

The total AFFOREST project is described in a book by Springer:
Environmental Effects of Afforestation in North-Western Europe - From Field Observations to Decision Support.

You might order the book at the internet:
http://www.springer.com/east/home?SGWID=5-102-22-173660090-0&changeHeader=true

The contents of the book are developed techniques to estimate the environmental impacts, guidelines and decision support systems (DSS) to enable national and international policy makers, but also forest managers, to maximize the benefits and minimize the adverse effects of afforestation. This book describes afforestation research and shows the application of the developed decision support system. The results should be applicable throughout northwest Europe and could be extended elsewhere. This book considers three of the most important environmental issues - carbon sequestration in soils and biomass, water surplus and nitrate leaching. The book describes the research to quantify these effects in the field and model them into the future. It will explain how the more detailed models were reduced to "metamodels" suitable for implementation within a real-time management system.
