Modelling carbon capture for Continental Portugal based on land cover changes
| Resumo: | Sustainable Development Goals number 13 and 15 settled by the United Nations in 2015 intends to tackle climate change and protect life on land by setting specific targets which are needed to be achieved over the next 12 years. Consequently, ecosystem services research, such as carbon sequestration and its climate regulatory function, have been highlighted. The land use, land-use change, and forestry (LULUCF) play a main role in the spatial modelling of carbon sequestration. In this study we used GIS and statistical tools to model carbon sequestration in mainland Portugal between years 2007 and 2010 based on land cover changes. A business as usual approach was adopted to extrapolate previous changes to 2020 and quantify the impact of existing land use and land cover policies on carbon capture. Results show that there was a negative variation, or a loss of carbon capture, of -5,4% between 2010 and 2020 at national level. For year 2020 the results at the district level followed the same pattern of the period from 2007 to 2010. The major negative variations between 2007 and 2010 were observed in Aveiro (-7,2%), Leiria (-5,6%) and Coimbra (-5,2%). Only Vila Real had slight increase in the carbon stored (0,8%). This approach may be useful for monitoring carbon storage over time and the provide environmental managers with tools to mitigate climate change more effectively. |
