The world\u2019s \u201cbest of the last\u201d tropical forests are at significant risk of being lost, according to a paper released today in Nature Ecology and Evolution<\/em><\/a>. Of these pristine forests that provide key services\u2014including carbon storage, prevention of disease transmission and water provision\u2014only a mere 6.5 percent are formally protected.<\/p>\n

In the study, supported by the United Nations Development Programme (UNDP), the National Aeronautics and Space Administration (NASA), Wildlife Conservation Society and involving scientists from eight leading research institutions\u2014including professor Scott Goetz<\/strong>, research professor Patrick Jantz <\/strong>and research associate Pat Burns<\/strong> of Northern Arizona University\u2019 School of Informatics, Computing, and Cyber Systems<\/a>\u2014researchers identified significant omissions in international forest conservation strategies. Current global targets focus solely on forest extent and fail to acknowledge the importance of forest intactness, or structural condition, creating a critical gap in action to safeguard ecosystems essential for human and planetary well-being.<\/p>\n

New targets that recognize forest quality are urgently needed to safeguard the Earth\u2019s precious humid tropical forests. Of the 1.9 million hectares of humid tropical forests globally, the study advocated for new protections in 41 percent of these areas, active restoration in 7 percent and reduction of human pressure in 19 percent to promote coordinated strategies to sustain forests of high ecological value.<\/p>\n

\u201cProtecting, restoring and sustainably managing nature is fundamental to achieving the Sustainable Development Goals but we need more robust spatial data to help us to do so,\u201d UNDP Administrator Achim Steiner said. \u201cBy serving as a convener to bring together some of the world\u2019s best scientists with governments, the United Nations is playing an important role in ensuring that this type of data and cutting-edge research is available to help countries plan and implement critical nature-based solutions.\u201d<\/p>\n

Collaborating with UNDP Country Offices and key stakeholders in Brazil, Colombia, Costa Rica, the Democratic Republic of the Congo, Ecuador, Indonesia, Peru and Vietnam, researchers mapped the location of high-quality forests using recently developed high-resolution maps of forest structure and human pressure across the global humid tropics.<\/p>\n

The paper reveals that the Earth\u2019s humid tropical forests, only half of which have high ecological integrity, are largely limited to the Amazon and Congo basins. The vast majority of these forests have no formal protection and, given recent rates of loss, are at significant risk.<\/p>\n

With the rapid disappearance of these \u201cbest of the last\u201d forests at stake, the paper provides a policy-driven framework for their conservation and restoration, recommending locations to maintain protections, add new protections, restore forest structure, and mitigate human pressure.<\/p>\n

\u201cNature-based approaches are emerging as high-value opportunities to deliver on international commitments and benefit people and the planet. NASA is proud to support rigorous science to understand the Earth and help organizations apply it to inform protection of the world\u2019s tropical forests,\u201d said Lawrence Friedl, director of NASA\u2019s Applied Sciences Program.<\/p>\n

The coming year is a so-called super year for biodiversity, in which the world will agree on a new deal for nature that will shape global action for the next 30 years. Countries also will have a final chance to revise their contributions to reduce carbon emissions before the Paris Climate Agreement goes into effect. Both these milestones will impact efforts to advance the nature-based Sustainable Development Goals of the 2030 Agenda.<\/p>\n

\u201cThe work reported in this paper is the result of a long process assessing the condition of the world\u2019s tropical forests,\u201d said Goetz, a co-author of the paper. \u201cThe breakthrough here was being able to use spaceborne satellite data to provide the first robust estimates of the structural condition of forests in three dimensions, not just forest canopy cover.\u201d<\/p>\n

“Advances in earth observation instruments and methodologies developed by NASA and partner institutions, coupled with the use of incredibly powerful computing systems like NAU’s Monsoon and Google Earth Engine, enabled a near-global mapping of tropical forest quality,\u201d Burns said. \u201cWe synthesized the best available earth observation datasets to map the changing condition of the Earth’s tropical forests, finding that only 6.5 percent of the highest-quality tropical forests are formally protected. We hope that the conservation strategies proposed as part of this international effort will be a step towards conserving high quality forests and restoring those that have been degraded.\u201d<\/p>\n

\u201cEvery year, research reveals new ways that old, structurally complex forests contribute to biodiversity, carbon storage, water resources, and many other ecosystem services. That we can now map such forests in great detail is an important step forward in efforts to conserve them,\u201d Jantz said.<\/p>\n
