Influence of Climatic Variables on Crown Condition in Pine Forests of Northern Spain

Abstract

Climate Change over the last century has created concern to the scientific community, as it could have a major impact on natural and social systems at local, regional and national scales. Greenhouse gasses emission has been modifying global climate, affecting ecosystems in very diverse ways (FAO 2012). Current mitigation policies derived from Kyoto Protocol are following two main strategies: reduction of gas emissions, and implementation of a sustainable development assuring persistence of greenhouse carbon sinks, including forests lands.
