Abstract Across the tropics, recent agricultural shifts have led to a rapid expansion of tree plantations, often into intact forest and grassland habitats. However, this expansion is poorly characterized. Here we report tropical tree plantation expansion between 2000 and 2012, based on classifying nearly 7 million unique patches of observed tree cover gain using optical and radar satellite imagery. Most observed gain patches (69.2%) consisted of small patches of natural regrowth (5.9 ± 0.2 Mha). However, expansion of tree plantations dominated observed increases in tree cover across the tropics (11.8 ± 0.2 Mha) with 92% of plantation expansion occurring in biodiversity hotspots and 14% in arid biomes. We estimate that tree plantations expanded into 9.2% of accessible protected areas across the humid tropics, most frequently in southeast Asia, west Africa, and Brazil. Given international tree planting commitments, it is critical to understand how future tree plantation expansion will affect remaining natural ecosystems. One Sentence Summary: Tree plantations dominated recent expansions of tropical tree cover, including into 9% of accessible parks in the humid tropics.

To date, numerous public- and private-sector efforts, commitments, and initiatives to reduce commodity-driven deforestation have emerged. In and of themselves, these elements—namely REDD+ programs, jurisdictional approaches (JAs), and private sector commitments—are necessary, but they are not sufficient to reduce deforestation. When operating together, however, these efforts have the potential to significantly reduce commodity-driven deforestation. This research aimed to determine whether and where REDD+ programs, JAs, and private sector commitments overlap in what are termed “trifecta jurisdictions”. Considering that each element possesses features that can enhance and complement those of the others, the authors hypothesized that—but did not ascertain whether—trifecta jurisdictions present the greatest potential to reduce commodity-driven deforestation. A total of 13 trifecta jurisdictions and six bifecta jurisdictions—where two of the three elements are present—were identified by: compiling a dataset of REDD+ programs, JAs, and private sector commitments; evaluating all potential options against established criteria; and categorizing them according to trifecta or bifecta jurisdiction status. The fact that a majority of trifecta and bifecta jurisdictions are located in countries with the most tropical tree cover loss is also significant in that it highlights the presence of these elements where most needed, and how high deforestation rates might be attracting REDD+ program, JA, and private sector commitment activities. Although many of the REDD+ programs, JAs, and private sector commitments are relatively nascent and their ability to collectively reduce deforestation is not yet clearly evident, this article posited that synergistic potential is greatest in trifecta and bifecta jurisdictions and that efforts should be made to greater align these elements.

Are strong fire-vegetation feedbacks needed to explain the spatial distribution of tropical tree cover?
