Abstract
Natural regeneration in previously deforested areas is the key to the restoration of forest cover in Nicaragua¿s agricultural border. The study aims to analyze the impact of land use changes on carbon stock in a Nicaragua livestock landscape during the past three decades. It was carried out in Matiguás, a sub-humid tropical region of Nicaragua, on today¿s predominant five land use types: shrub-land (SL), intervened secondary forest (ISF), pasture with high tree density (PHD), pasture with low tree density (PLD) and degraded pasture (DP). The land use classes were identified using geographical data as orthophotos, satellite imagery, and soil and vegetation maps, followed by a field survey. The research is based on the analysis of Landsat 5 TM/8 OLI imagery and in situ carbon measurements. Remote sensing offers a rapid and effective tool for mapping vegetation through satellite imagery classification, and can also be used to furnish statistical and spatial data with regard to the state of deforestation for a given region. Nearly cloud-free Landsat images: a Landsat 5 Thematic Mapper image from 1986 and a Landsat 8 OLI scene from 2015 were the datasets used in the study, both from the dry season (December to March). For the analysis of aboveground biomass carbon and soil organic carbon, twenty sampling plots were located in the study area with four replicates for each land use. Comparing the carbon stock, our results indicate a trend of increasing carbon values between 1986 and 2015. The rise of carbon stock is closely linked to the land use changes, which are oriented to the main economic activity of the area, which is livestock production. The advances of our research underpin scientific efforts to connect dynamic land use change with ecosystem service of carbon storage in livestock landscapes, implementing traditional silvopastoral systems as tools.
