  • Degradation and deforestation increase the sensitivity of the Amazon Forest to climate extremes

    Open AccessMarcos Longo, Michael Keller et al.ARTICLEEnvironmental Research Letters2025

    About 40% of the Brazilian Amazon has been deforested or suffered changes in forest structure through degradation (selective logging, fires, and fragmentation). The impact of forest degradation on the forest’s sensitivity to climate extremes has not been fully explored because of a lack of data and the complex interplay of forest structure and climate drivers. Here, we combined forest structure data from 545 airborne lidar transects (375 ha each)…

  • Unveiling spatial variations of high forest live biomass carbon stocks of Gabon using advanced remote sensing techniques

    Open AccessLe Bienfaiteur Takougoum Sagang, Samuel Favrichon et al.ARTICLEEnvironmental Research Letters2024

    Gabon is one of 11 high-forest, low-deforestation (HFLD) countries in the world. It has the highest proportion of preserved forests in the Congo Basin and is the first country to create large forest carbon offset credits in the market. However, about 60% of forests in Gabon is allocated to logging concessions, causing concerns for forest degradation and the sustainability of carbon credits. Here, we use a combination of air- and space-borne remot…

  • Making the US national forest inventory spatially contiguous and temporally consistent

    Open AccessYifan Yu, Sassan Saatchi et al.ARTICLEEnvironmental Research Letters2022

    Signatories to the United Nations Framework Convention on Climate Change (UNFCCC) are required to annually report economy-wide greenhouse gas emissions and removals, including the forest sector. National forest inventory (NFI) is considered the main source of data for reporting forest carbon stocks and changes to UNFCCC. However, NFI samples are often collected asynchronously across regions in intervals of 5–10 years or sub-sampled annually, both…

  • The Nasa Carbon Monitoring System Phase 2 synthesis: Scope, findings, gaps and recommended next steps

    Open AccessG C Hurtt, A E Andrews et al.ARTICLEEnvironmental Research Letters2022

    Underlying policy efforts to address global climate change is the scientific need to develop the methods to accurately measure and model carbon stocks and fluxes across the wide range of spatial and temporal scales in the Earth system. Initiated in 2010, the NASA Carbon Monitoring System is one of the most ambitious relevant science initiatives to date, exploiting the satellite remote sensing resources, computational capabilities, scientific know…

  • Detecting vulnerability of humid tropical forests to multiple stressors

  • Mapping tree diversity in the tropical forest region of Chocó-Colombia

    Open AccessJ Camilo Fagua, Patrick Jantz et al.ARTICLEEnvironmental Research Letters2021

    Understanding spatial patterns of diversity in tropical forests is indispensable for their sustainable use and conservation. Recent studies have reported relationships between forest structure and α -diversity. While tree α -diversity is difficult to map via remote sensing, large-scale forest structure models are becoming more common, which would facilitate mapping the relationship between tree α -diversity and forest structure, contributing to o…

  • Mapping carbon accumulation potential from global natural forest regrowth

  • Below-surface water mediates the response of African forests to reduced rainfall

    Open AccessNima Madani, John S Kimball et al.ARTICLEEnvironmental Research Letters2020

    Terrestrial ecosystem gross primary productivity (GPP) is the largest land-atmosphere carbon flux and the primary mechanism of photosynthetic fixation of atmospheric CO 2 into plant biomass. Anomalous rainfall events have been shown to have a great impact on the global carbon cycle. However, less is known about the impact of these events on GPP, especially in Africa, where in situ observations are sparse. Here, we use a suite of satellite and oth…

  • Human and Climate Effects on the Hamoun Wetlands

    Open AccessSaeideh Maleki, Saeid Soltani Koupaei et al.ARTICLEWeather, Climate, and Society2019

    Negative impacts of climate change on ecosystems have been increasing, and both the intensification and the mitigation of these impacts are strongly linked with human activities. Management and reduction of human-induced disturbances on ecosystems can mitigate the effects of climate change and enhance the ecosystem recovery process. Here, we investigate coupled human and climate effects on the wetland ecosystem of the lower Helmand basin from 197…

  • St Century drought-related fires counteract the decline of Amazon deforestation carbon emissions

    Open AccessLuiz Eduardo O C Aragão, Liana O Anderson et al.ARTICLENature Communications2018

    Tropical carbon emissions are largely derived from direct forest clearing processes. Yet, emissions from drought-induced forest fires are, usually, not included in national-level carbon emission inventories. Here we examine Brazilian Amazon drought impacts on fire incidence and associated forest fire carbon emissions over the period 2003–2015. We show that despite a 76% decline in deforestation rates over the past 13 years, fire incidence increas…

  • Carbon storage potential in degraded forests of Kalimantan, Indonesia

    Open AccessAntónio Ferraz, Sassan Saatchi et al.ARTICLEEnvironmental Research Letters2018

    The forests of Kalimantan are under severe pressure from extensive land use activities dominated by logging, palm oil plantations, and peatland fires. To implement the forest moratorium for mitigating greenhouse gas emissions, Indonesia's government requires information on the carbon stored in forests, including intact, degraded, secondary, and peat swamp forests. We developed a hybrid approach of producing a wall-to-wall map of the aboveground b…

  • Chapter 10. Trees have Already been Invented: Carbon in Woodlands

    Open AccessSusanna B Hecht, Keith Pezzoli et al.ARTICLECollabra2016

    In the developed world, discussions of climate change mitigation and adaptation tend to focus on technological solutions such as decarbonizing electric grids and regulating emissions of methane, black carbon, and so on. However, an often overlooked strategy for reaching greenhouse gas reduction targets in much of the developing world is rooted, not in new technologies, but in vegetation management. Trees and other vegetation absorb carbon as they…

  • Satellite observation of tropical forest seasonality: Spatial patterns of carbon exchange in Amazonia

    Open AccessLiang Xu, Sassan Saatchi et al.ARTICLEEnvironmental Research Letters2015

    Determining the seasonality of terrestrial carbon exchange with the atmosphere remains a challenge in tropical forests because of the heterogeneity of ecosystem and climate. The magnitude and spatial variability of this flux are unknown, particularly in Amazonia where empirical upscaling approaches from spatially sparse in situ measurements and simulations from process-based models have been challenged in recent scientific literature. Here, we us…

  • Sunlight mediated seasonality in canopy structure and photosynthetic activity of Amazonian rainforests

    Open AccessJian Bi, Yuri Knyazikhin et al.ARTICLEEnvironmental Research Letters2015

    Resolving the debate surrounding the nature and controls of seasonal variation in the structure and metabolism of Amazonian rainforests is critical to understanding their response to climate change. In situ studies have observed higher photosynthetic and evapotranspiration rates, increased litterfall and leaf flushing during the Sunlight-rich dry season. Satellite data also indicated higher greenness level, a proven surrogate of photosynthetic ca…

  • Baseline Map of Carbon Emissions from Deforestation in Tropical Regions

    Open AccessNancy L Harris, Sandra Brown et al.ARTICLEScience2012

    Tropical Carbon Loss Accurate and precise measures of tropical deforestation and the resulting carbon emissions are needed in order to formulate climate policy. Harris et al. (p. 1573 ; see the Perspective by Zarin ) used satellite observations of deforestation within the tropics of three continents to estimate that gross annual carbon emissions were approximately 0.8 Pg Cyr −2 (Pg = 10 15 g) for the years 2000 to 2005, from the loss of 43 millio…

  • Benchmark map of forest carbon stocks in tropical regions across three continents

    Open AccessSassan Saatchi, Sassan S Saatchi et al.ARTICLEProceedings of the National…2011

    Developing countries are required to produce robust estimates of forest carbon stocks for successful implementation of climate change mitigation policies related to reducing emissions from deforestation and degradation (REDD). Here we present a “benchmark” map of biomass carbon stocks over 2.5 billion ha of forests on three continents, encompassing all tropical forests, for the early 2000s, which will be invaluable for REDD assessments at both pr…

  • Using Remote Sensing to Map the Risk of Human Monkeypox Virus in the Congo Basin

    Open AccessTamara L Fuller, Trevon Fuller et al.ARTICLEEcoHealth2011

    Although the incidence of human monkeypox has greatly increased in Central Africa over the last decade, resources for surveillance remain extremely limited. We conducted a geospatial analysis using existing data to better inform future surveillance efforts. Using active surveillance data collected between 2005 and 2007, we identified locations in Sankuru district, Democratic Republic of Congo (DRC) where there have been one or more cases of human…

  • Globalization and Forest Resurgence: Changes in Forest Cover in El Salvador

    Susanna B Hecht, Sassan Saatchi et al.ARTICLEBioScience2007

    Globalization is often associated with deforestation, but its impacts on forest recovery are less known. We analyzed socioeconomic data, land-use surveys, and satellite imagery to monitor changes in woody cover in El Salvador from the early 1990s to the present. Even where rural population density exceeded 250 people per square kilometer, we documented a 22% increase in the area with more than 30% tree cover, and a 7% increase in the area with mo…
