Abstract
  • The research was conducted in the Fundo Almendra, property of the National University of the Peruvian Amazon (UNAP). The objective was to analyze the gross forest loss in the period 2001-2021 in Fundo Almendra, the relationship between forest loss and local surface temperature, and the role of local communities’ demographics and economies in driving deforestation. A mixed approach was used, combining: (i) a spatio-temporal (quantitative) analysis to analyze forest loss and local temperature (objectives 1 and 2); and (ii) a qualitative analysis to triangulate the quantitative results on forest loss and local temperature and to analyze the drivers of deforestation. The results indicate that the total gross forest loss in Fundo Almendra in the period 2001-2021 amounts to 408,63 ha and the average annual forest loss is 19,46 ha. Forest loss is partly driven by (i) small-scale agriculture practiced by local (non-indigenous) communities to satisfy basic economic needs and (ii) the expansion of human settlements (area) due to population growth in such communities. Regarding the relationship between forest cover and surface temperature, there is an abrupt increase in surface temperature in an area that suddenly loses its forest cover in 2013, but the surface temperature quickly starts dropping back to normal levels in 2014, as the forest starts to regenerate. On the other hand, a forested area that has not been disturbed shows an almost constant average surface temperature. I conclude that gross forest loss in the Fundo Almendra in the last two decades shows significant values, but that further research is needed, for instance to assess the net forest loss, considering potential forest cover gains. There are limitations and assumptions inherent to remote sensing that need to be carefully considering when obtaining, analyzing and interpreting data on forest loss and surface temperature. A better definition of forest is needed to avoid underestimation or overstimation when making political and administrative decisions. In addition, the UNAP has the possibility of promoting multidisciplinary research, including topics on degradation and restoration of ecosystems, working with the communities of Puerto Almendra and Nina Rumi.
