ArticleJournal articleDeforestation trends and impact assessment of protected area designation in the South American tri-national Atlantic forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The South-American Atlantic Forest region spans the nations of Argentina, Brazil and Paraguay. It is one of the most ecologically diverse in the world, yet one of the most vulnerable to deforestation with little research examining trends and drivers. Conservation interventions can play a critical role in protecting this forest, but the impact of their implementation remains unclear. We assessed the effects of forest protected area (FPA) designation on avoided deforestation across the Atlantic Forest region between 2000 and 2020 using the most recently available remote-sensed data in combination with geo-referenced socio-economic descriptors. Applying a pseudo-randomized approach, we quantified factors explaining establishment of FPAs and compared deforestation rates. Results show FPA designation lowered the odds of deforestation by about 14%, which is significantly higher than past assessments in other Latin American regions. Effectively, the estimated deforestation rate within FPA-designated areas (~5%) was nearly four-times lower than in non-FPA forests (19%). Future studies are needed to assess the impacts of FPAs on the socioeconomic wellbeing of forest-dependent communities across the Atlantic forest.

ArticleJournal articleAre we getting there? Community and external perceptions of collaborative timber management in three amazonian sustainable use protected areas
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.As the number of communities that have (partial) rights to manage forests has increased, so has the number of communities that engage with timber management in sustainable use protected areas. Guided by two research questions: (1) How do local communities and external organizations perceive timber co-management arrangements and logging activities in sustainable use protected areas? and (2) To what extent do these actors' perceptions vary?, I investigated actors’ perceptions of timber co-management arrangements and logging activities in three Brazilian Amazonian sustainable use protected areas. Based on participatory research methods involving both individual and group interviews, results suggest four main things: (1) strong and long-term partnerships among multiple actors can enhance positive perceptions of collaboration in co- management systems; (2) timber workers should be more involved in technical decision makings with external partner organizations; (3) Participatory budgeting can be key to equate perceptions on income generation; and (4) Conflict management can be imperative in co-management systems, still when underestimated by some of the co-management actors.

ArticleJournal articleImprovement of the forest cover-changes cartography from global forest change for critical deforestation regions in Mexico. Case of the Lacandona Region 2014-2021
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Global Forest Change (GFC) is a global monitoring system with moderate resolution (Landsat, 30 m pixel) that allows knowing the location and magnitude of the losses or gains of global forest cover. Critical Forest Change (CFC) is a calibration system based on comprehensive photo interpretation (1:10,000 scale for change editing, and 1:5,000 scale for interpretation- confirmation of change strata), with diagnostic criteria supported by field data of the National Forest Inventory (scale 1:1, period 2014-2021). CFC reduces until 85.8% the overestimation of the forest loss of GFC in the case of the Lacandona Region (327,646 ha). The process included the analysis of data at 330 study sites and the interpretation of 1,190 frames of Spot-6 (April 28, 2014) versus Sentinel-2 (April 24, 2021) in higher resolution (10 m). The annual rate of forest loss obtained by GFC (4,526 ha.yr-1) is 1.87 times higher than the LFC rate (2,415 ha.yr-1). Through a comparative analysis between the cartography of GFC and CFC, it was possible to identify that 19.2% of the differences correspond to phenological changes (leaf fall deciduous, greenness variation, or alteration of the biomass due to eventual changes in humidity). 31.3% by Landsat spatial resolution limitations, 3.8% occurs in changes by industrial plantations, 11.6% of the differences can reduce by eliminating the GFC residuals outside the forest FAO definition (changes less than 0.5 ha), 7.4% of the differences correspond to atmospheric noise in the interpreted images, 6.8% to visual omissions and 19.9% there are no changes by interpretation. The cartographic adjustment of GFC by CFC is relatively fast (1,000 ha.hr-1 per photointerpreter-expert). Its implementation improves the spatial coherence, periodicity, and legibility of the areas of change, strengthening the relevance of both systems in local policy decisions.
