Abstract
Abstract Between 2005 and 2015, the forest area occupied by maritime pine trees in Continental Portugal decreased by about 10.6%, and the existing volume decreased by about 18.4% mainly due to fires and pests (e.g., nematode) that occurred during this period. The purpose of this study was to study the evolution of the land use environmental impact of 1 m3 of maritime pine, standing in Portuguese forest, during that period using the model by Milà i Canals based on soil organic matter measured by soil organic carbon. Results show that the land use impact category increased from 16,812 kg C deficit in 2005 to 18,423 kg C deficit in 2015. Land transformation to forest roads is the main contribution for land use impact representing 54% of the total value followed by land occupation as forest that represents about 40%.
Highlights
The new EU forest strategy for 2030 [1] recognises that “forests and the forest-based sector is an essential part of Europe’s transition to a modern, climate neutral, resourceefficient and competitive economy.” If at least three billion additional trees will be planted across Europe by 2030 as proposed in the strategy, forests will play a vital role in making Europe the first climate neutral continent by 2050 and for meeting the European Green Deal objectives
Using equation (1) and characterization factors (CFs) from Tables 2 and 3, the substances derived from the inventory table (Table 1) were converted into indicators of the land use impact category for the functional unit (FU)
This article proposed to study the evolution of the land use impact category of Portuguese maritime pine between 2005 and 2015 using the method proposed by Milà i Canals et al [21] based on soil organic matter (SOM)
Summary
The new EU forest strategy for 2030 [1] recognises that “forests and the forest-based sector is an essential part of Europe’s transition to a modern, climate neutral, resourceefficient and competitive economy.” If at least three billion additional trees will be planted across Europe by 2030 as proposed in the strategy, forests will play a vital role in making Europe the first climate neutral continent by 2050 and for meeting the European Green Deal objectives (reducing net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels). If at least three billion additional trees will be planted across Europe by 2030 as proposed in the strategy, forests will play a vital role in making Europe the first climate neutral continent by 2050 and for meeting the European Green Deal objectives (reducing net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels). To fit this objective, a new proposal [2]. According to the same source, the main contributors for this increase have been an increase in removals in forest land and in other land and reductions in emissions in cropland and grassland
