ArticleAssessing land use and cover change, forest degradation and secondary forest databases for better understand of airborne CO2 measurements over the Brazilian Amazon

No results found.Tropical forests are essential for ecosystem services provision and for climate change mitigation. Amazon forest, the largest continue tropical forests in the world, have been decreasing due to deforestation and forest degradation. Brazil, a country containing most of the Amazon forests, also presents the highest deforestation rates within the Pan-Amazonian countries. The CARBAM project has been collecting bimonthly CO2 atmospheric measurements from an airplane since 2010 in the Brazilian Amazon, showing that there is a reduction on the forest capacity to absorb carbon for deforestation and climate change patterns. To understand these CO2 fluxes, we need to analyze the land use and cover change processes including forest degradation and secondary forest growth. Our goal is to assess different databases to better understand deforestation, degradation and secondary forest dynamics in the Amazon. For this, we merged different databases for the period 2010-2018: MapBiomas for land use and cover change; PRODES for deforestation; Bullock et al. (2020) for degradation; and Silva et al. (2020) for secondary forest. We found that, from the total accumulated deforested area in 2018 (17% of the Brazilian Amazon), pasture represent 69% fallowed by secondary vegetation 21% and agriculture 8%. The annual deforested area, smaller than secondary vegetation area, is increasing since 2012. Degradation has a different area each year. The carbon uptake by secondary forest and degradation dynamics is underestimated in the national communications of greenhouse gases, and its mapping is extremely relevant to policy makers to accomplish the National Determined Contribution. The large pasture areas deserve attention because it may permit the secondary forest to increase and provide agriculture expansion areas, decreasing in this way the pressure for deforestation and degradation of primary forest and contributing to preserve biodiversity and ecosystem services of the Amazon forests.

Book (series)Report of the workshop on “How to leverage the Illuminating Hidden Harvests approach for better small-scale fisheries data", Rome, 14–15 March 2023 2024
Also available in:
No results found.The workshop on How to leverage the Illuminating Hidden Harvests approach for better small-scale fisheries data explored how the results and methodology of the study Illuminating Hidden Harvests: The contributions of small-scale fisheries to sustainable development study (IHH) can be leveraged to support the improvement of small-scale fisheries data, with a view to inform management and policy. The IHH is a global initiative of the Food and Agriculture Organization of the United Nations (FAO), Duke University and WorldFish carried out in support of the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines). The IHH report, published in March 2023, provides new evidence about the benefits, interactions and impacts of small-scale fisheries to inform policy and practice.This workshop focused on sub-Saharan Africa as a starting point; however, in the future, collaboration and support could extend to other regions. The workshop concluded that there is considerable value in both the IHH approach and the data already collected that can be capitalized on, at both national and regional levels, taking country priorities into account. Small-scale fisheries organizations should be further empowered for engagement in relevant policy processes by equipping them with IHH data and information, and partnerships should be sought also outside the fisheries sector. Tailored communication pathways and products for diverse audiences will be needed, including multiple language translations and simplified versions of the IHH report. Using the IHH results and approach wisely will help improve the knowledge on the subsector and contribute to sustainable development. -
Brochure, flyer, fact-sheetNational forest monitoring system provides better data, and enhances capacity in Papua New Guinea
Enhancing land use planning and monitoring of forest-related interventions through transparent and accurate forest data and information for climate action
2021Working with Costa Rica, Papua New Guinea proposed the concept of reducing emissions from deforestation and forest degradation (REDD+) to the United Nations Framework Convention on Climate Change (UNFCCC) in 2005. Ever since, the country has continued to prepare for REDD+ and has worked to establish a National Forest Monitoring System (NFMS). These actions are vital, as accurate information regarding forest status and change is essential for sustainable management of the nation's forest. The Climate Change and Development Authority (CCDA) and the Papua New Guinea Forest Authority (PNGFA) are the core-implementing partners that jointly developed the country’s NFMS, and they receive support from a number of stakeholders and other actors, including FAO. This case study reviews the main objectives of the county's NFMS, highlights key stakeholders and defines successes and challenges of implementation. Ultimately, this case study serves as a reference for other countries implementing NFMS and preparing for REDD+.
