Significance Most nations recently agreed to hold global average temperature rise well below 2 °C. We examine how much climate mitigation nature can contribute this goal with a comprehensive analysis of “natural solutions” (NCS): 20 conservation, restoration, and/or improved land management actions that increase carbon storage avoid greenhouse gas emissions across forests, wetlands, grasslands, and agricultural lands. show NCS provide over one-third the cost-effective needed between now 2030...
Limiting climate warming to <2°C requires increased mitigation efforts, including land stewardship, whose potential in the United States is poorly understood. We quantified of natural solutions (NCS)—21 conservation, restoration, and improved management interventions on agricultural lands—to increase carbon storage avoid greenhouse gas emissions States. found a maximum 1.2 (0.9 1.6) Pg CO2e year−1, equivalent 21% current net annual At market prices (USD 10 per Mg CO2e), 299 Tg year−1 could...
Selective logging causes at least half of the emissions from tropical forest degradation. Reduced-impact for climate (RIL-C) is proposed as a way to maintain timber production while minimizing damage. Here we synthesize data 61 coordinated field-based surveys impacts in seven countries across tropics. We estimate that selective emitted 834 Tg CO2 2015, 6% total greenhouse gas emissions. Felling, hauling, and skidding caused 59%, 31%, 10% these emissions, respectively. suggest RIL-C incentive...
Restoring forest cover is a prominent option for climate mitigation. Effective deployment requires knowing where opportunities are and how they vary in carbon capture, costs, co-benefits, feasibility. Here, we combined spatial, economic, feasibility analyses to examine 10 different opportunity classes restoration of across the contiguous United States. These include non-stocked forests, shrublands, protected areas, post-burn landscapes, pasture lands, croplands with challenging soils, urban...
Abstract Many countries have made ambitious pledges to increase forest areas mitigate climate change. However, the availability of land meet these goals is not well understood. Global studies indicate substantial potential, but do account for local land‐use and regional variation, crucial policy making. Using India as a case study, we use machine learning framework define bioclimatic envelope cover map this against current land‐uses with varying suitability restoration. We estimate...
The selective logging that characterizes most timber extraction operations in the tropics leaves large patches of blocks (i.e., areas allocated for harvesting) intact, without evidence direct impacts. For example, ~10,000 ha sampled 48 forest management enterprises Africa (Gabon, Republic Congo, and Democratic Congo), Indonesia, Suriname, Mexico, an average 69% (range 20–97%) area was not directly affected by harvests. proportion intact within decreased very slightly with increases harvest...
The spread and uptake of new ideas (diffusion innovations) is critical for organizations to adapt over time, but there little evidence how this happens within their broader community. To address this, we analyzed individuals accessed information about a recent science innovation at large, international, biodiversity conservation non-profit–The Nature Conservancy–and then traced the flow was shared organization externally, drawing on an exceptionally data-rich environment. We used surveys...

This is especially problematic Indian savannas which have been historically misclassified as degraded forests are targeted for tree-planting. Here, we examine biome determinants through lens tree cover India. Our analyses reveal four distinct zones differing cover, with...

Ecosystem restoration is inherently a complex activity with inevitable tradeoffs in environmental and societal outcomes. These can potentially be large when policies practices are focused on single outcomes versus joint achievement of multiple Few studies have assessed the Nature’s Contributions to People (NCP) distributional equity NCP from forest strategies. Here, we optimized defined area across India systematic conservation planning assess between three NCP: i) climate change mitigation...
A large number of species in the tropics are awaiting discovery, many due to their cryptic morphology ie. lack discernable morphological difference. We explored presence lineages within frog genera, Indirana and Walkerana, which endemic Western Ghats Peninsular India. By reconstructing a phylogeny using 5 genes robust geographic sampling, we delimited 19 along population—species continuum, multiple criteria including haplotype clusters, genetic distance, distinctness, geographical...
We provide our five visions and contributions that the young tropical restoration science community can make for an impactful beneficial UN Decade on Ecosystem Restoration. Protecting ecosystems, in their current extent function, is no longer sufficient to meet global conservation sustainable development goals: we must also restore ecosystems remedy past degradation (Gann et al., 2019; Leclère 2020). Although ecosystem needed globally, focusing efforts tropics may largest benefits humans...
