An integrated pan-tropical biomass map using multiple reference datasets

Global Change Biology, Vol. 22, No. 4. (April 2016), pp. 1406-1420,


We combined two existing datasets of vegetation aboveground biomass (AGB) (Proceedings of the National Academy of Sciences of the United States of America, 108, 2011, 9899; Nature Climate Change, 2, 2012, 182) into a pan-tropical AGB map at 1-km resolution using an independent reference dataset of field observations and locally calibrated high-resolution biomass maps, harmonized and upscaled to 14 477 1-km AGB estimates. Our data fusion approach uses bias removal and weighted linear averaging that incorporates and spatializes the biomass patterns ...


Human appropriation of photosynthesis products

Science, Vol. 294, No. 5551. (2001), pp. 2549-2552,


Previous global estimates of the human impact on terrestrial photosynthesis products depended heavily on extrapolation from plot-scale measurements. Here, we estimated this impact with the use of recent data, many of which were collected at global and continental scales. Monte Carlo techniques that incorporate known and estimated error in our parameters provided estimates of uncertainty. We estimate that humans appropriate 10 to 55% of terrestrial photosynthesis products. This broad range reflects uncertainty in key parameters and makes it difficult to ascertain ...


Can recent pan-tropical biomass maps be used to derive alternative Tier 1 values for reporting REDD+ activities under UNFCCC?

Environmental Research Letters, Vol. 9 (2014), 124008,


The IPCC Guidelines propose 3 Tier levels for greenhouse gas monitoring within the forest land category with a hierarchical order in terms of accuracy, data requirements and complexity. Due to missing data and/or capacities, many developing countries, potentially interested in the reducing emissions from deforestation and forest degradation scheme, have to rely on Tier 1 default values with highest uncertainties. A possible way to increase the credibility of uncertain estimates is to apply a conservative approach, for which standard statistical information ...


Forest Biodiversity



[Excerpt] Tropical, temperate and boreal forests offer a diverse set of habitats for plants, animals and micro-organisms. Consequently forests hold the majority of the world’s terrestrial species. However these biologically rich systems are increasingly threatened, largely as a result of human activity. [What is Forest Biological Diversity?] Forest biological diversity is broad term referring to all the life forms found within forested areas and the ecological roles they perform. As such, forest biological diversity encompasses not just trees but the multitude of plants, animals ...


Enviro-Net: from networks of ground-based sensor systems to a web platform for sensor data management

Sensors, Vol. 11, No. 6. (17 June 2011), pp. 6454-6479,


Ecosystems monitoring is essential to properly understand their development and the effects of events, both climatological and anthropological in nature. The amount of data used in these assessments is increasing at very high rates. This is due to increasing availability of sensing systems and the development of new techniques to analyze sensor data. The Enviro-Net Project encompasses several of such sensor system deployments across five countries in the Americas. These deployments use a few different ground-based sensor systems, installed at different ...


Increasing human dominance of tropical forests

Science, Vol. 349, No. 6250. (21 August 2015), pp. 827-832,


Tropical forests house over half of Earth’s biodiversity and are an important influence on the climate system. These forests are experiencing escalating human influence, altering their health and the provision of important ecosystem functions and services. Impacts started with hunting and millennia-old megafaunal extinctions (phase I), continuing via low-intensity shifting cultivation (phase II), to today’s global integration, dominated by intensive permanent agriculture, industrial logging, and attendant fires and fragmentation (phase III). Such ongoing pressures, together with an intensification of global environmental ...


Climatic impact of global-scale deforestation: radiative versus nonradiative processes

Journal of Climate, Vol. 23, No. 1. (1 January 2010), pp. 97-112,


A fully coupled land-ocean-atmosphere GCM is used to explore the biogeophysical impact of large-scale deforestation on surface climate. By analyzing the model sensitivity to global-scale replacement of forests by grassland, it is shown that the surface albedo increase owing to deforestation has a cooling effect of -1.36 K globally. On the other hand, forest removal decreases evapotranspiration efficiency and decreases surface roughness, both leading to a global surface warming of 0.24 and 0.29 K, respectively. The net biogeophysical impact of deforestation ...

[Significance] People are fascinated by the amazing diversity of tropical forests and will be surprised to learn that robust estimates of the number of tropical tree species are lacking. We show that there are at least 40,000, but possibly more than 53,000, tree species in the tropics, in contrast to only 124 across temperate Europe. Almost all tropical tree species are restricted to their respective continents, and the Indo-Pacific region appears to be as species-rich as tropical America, with each of these ...

Targeted carbon conservation at national scales with high-resolution monitoring

Proceedings of the National Academy of Sciences, Vol. 111, No. 47. (25 November 2014), pp. E5016-E5022,


[Significance] Land use is a principal driver of carbon emissions, either directly through land change processes such as deforestation or indirectly via transportation and industries supporting natural resource use. To minimize the effects of land use on the climate system, natural ecosystems are needed to offset gross emissions through carbon sequestration. Managing this critically important service must be achieved tactically if it is to be cost-effective. We have developed a high-resolution carbon mapping approach that can identify biogeographically explicit targets for carbon ...


Linking Remote-Sensing Information to Tropical Forest Structure: The Crucial Role of Modelling

IEEE Earthzine, Vol. 5, No. 2. (2012), 369968


Using remote sensing to provide reliable information over extensive areas of dense and heterogeneous tropical forests is a challenging task. Not only is the task challenging, but it also has become closely related to global concerns about reducing greenhouse gas emissions from deforestation and forest degradation, also known as the REDD process. The AMAP laboratory in Montpellier, France, is contributing to this challenge at the interface between signal processing and plant and vegetation modelling which is its central domain of expertise. ...


Global Forest Transition: Prospects for an End to Deforestation

Annual Review of Environment and Resources, Vol. 36, No. 1. (2011), pp. 343-371,


Although global rates of tropical deforestation remain alarmingly high, they have decreased over the period 2000–2010, and a handful of tropical developing countries have recently been through a forest transition—a shift from net deforestation to net reforestation. This review synthesizes existing knowledge on the occurrence, causes, and ecological impacts of forest transitions and examines the prospects and policy options for a global forest transition. The ecological quality of forest transitions depends on multiple factors, including the importance of natural forest regeneration ...


Forest Cover Changes in Tropical South and Central America from 1990 to 2005 and Related Carbon Emissions and Removals

Remote Sensing, Vol. 4, No. 5. (11 May 2012), pp. 1369-1391,


This paper outlines the methods and results for monitoring forest change and resulting carbon emissions for the 1990–2000 and 200–2005 periods carried out over tropical Central and South America. To produce our forest change estimates we used a systematic sample of medium resolution satellite data processed to forest change maps covering 1230 sites of 20 km by 20 km, each located at the degree confluence. Biomass data were spatially associated to each individual sample site so that annual carbon emissions could ...


Estimating tropical deforestation from Earth observation data

Carbon Management, Vol. 1, No. 2. (1 December 2010), pp. 271-287,


This article covers the very recent developments undertaken for estimating tropical deforestation from Earth observation data. For the United Nations Framework Convention on Climate Change process it is important to tackle the technical issues surrounding the ability to produce accurate and consistent estimates of GHG emissions from deforestation in developing countries. Remotely-sensed data are crucial to such efforts. Recent developments in regional to global monitoring of tropical forests from Earth observation can contribute to reducing the uncertainties in estimates of carbon ...


A large-scale field assessment of carbon stocks in human-modified tropical forests

Glob Change Biol (1 May 2014), pp. n/a-n/a,


Tropical rainforests store enormous amounts of carbon, the protection of which represents a vital component of efforts to mitigate global climate change. Currently, tropical forest conservation, science, policies, and climate mitigation actions focus predominantly on reducing carbon emissions from deforestation alone. However, every year vast areas of the humid tropics are disturbed by selective logging, understory fires, and habitat fragmentation. There is an urgent need to understand the effect of such disturbances on carbon stocks, and how stocks in disturbed forests ...


Deforestation: carving up the Amazon

Nature, Vol. 509, No. 7501. (21 May 2014), pp. 418-419,


A rash of road construction is causing widespread change in the world's largest tropical forest with potentially global consequences. [excerpt] The drying brought about by roads influences local atmospheric circulation patterns and can have farther-reaching effects that not only compromise the health of the Amazon but can also contribute to global warming by releasing carbon stored in the forest. [...] Stripping away trees not only eliminates a source of moisture; it also changes the regional air flow. As the forest dries, ...


Functional megadiversity

Proceedings of the National Academy of Sciences, Vol. 111, No. 16. (22 April 2014), pp. 5763-5764,


[Excerpt] Western Amazonian and Andean forests have Earth’s highest biodiversity and are globally important for ecosystem services and climate regulation. Straddling the planet’s longest ecological gradients, they have captured the imagination of scientists since von Humboldt (1). However, ecological studies and theory have incorporated that spectacular biological variation in only the most rudimentary ways, or not at all. It is widely understood that there are many traits that are important to plant performance, consequential not only for things like carbon gain ...


The velocity of climate change

Nature, Vol. 462, No. 7276. (24 December 2009), pp. 1052-1055,


The ranges of plants and animals are moving in response to recent changes in climate1. As temperatures rise, ecosystems with ‘nowhere to go’, such as mountains, are considered to be more threatened2, 3. However, species survival may depend as much on keeping pace with moving climates as the climate’s ultimate persistence4, 5. Here we present a new index of the velocity of temperature change (km yr-1), derived from spatial gradients (°C km-1) and multimodel ensemble forecasts of rates of temperature increase (°C yr-1) ...


The carbon balance of tropical, temperate and boreal forests

Plant, Cell and Environment, Vol. 22, No. 6. (June 1999), pp. 715-740,


Forest biomes are major reserves for terrestrial carbon, and major components of global primary productivity. The carbon balance of forests is determined by a number of component processes of carbon acquisition and carbon loss, and a small shift in the magnitude of these processes would have a large impact on the global carbon cycle. In this paper, we discuss the climatic influences on the carbon dynamics of boreal, temperate and tropical forests by presenting a new synthesis of micrometeorological, ecophysiological and ...


Sustainability: Choose satellites to monitor deforestation

Nature, Vol. 496, No. 7445. (17 April 2013), pp. 293-294,


Illegal logging threatens tropical forests and carbon stocks. Governments must work together to build an early warning system, say Jim Lynch and colleagues. ...


Estimation of tropical rain forest aboveground biomass with small-footprint lidar and hyperspectral sensors

Remote Sensing of Environment, Vol. 115, No. 11. (November 2011), pp. 2931-2942,


Tropical forests are an important component of the global carbon balance, yet there is considerable uncertainty in estimates of their carbon stocks and fluxes, which are typically estimated through analysis of aboveground biomass in field plots. Remote sensing technology is critical for assessing fine-scale spatial variability of tropical forest biomass over broad spatial extents. The goal of our study was to evaluate relatively new technology, small-footprint, discrete-return lidar and hyperspectral sensors, for the estimation of aboveground biomass in a Costa Rican ...


Re-evaluation of forest biomass carbon stocks and lessons from the world's most carbon-dense forests

Proceedings of the National Academy of Sciences, Vol. 106, No. 28. (14 July 2009), pp. 11635-11640,


From analysis of published global site biomass data (n = 136) from primary forests, we discovered (i) the world's highest known total biomass carbon density (living plus dead) of 1,867 tonnes carbon per ha (average value from 13 sites) occurs in Australian temperate moist Eucalyptus regnans forests, and (ii) average values of the global site biomass data were higher for sampled temperate moist forests (n = 44) than for sampled tropical (n = 36) and boreal (n = 52) forests (n ...


Exploring the likelihood and mechanism of a climate-change-induced dieback of the Amazon rainforest

Proceedings of the National Academy of Sciences In Proceedings of the National Academy of Sciences, Vol. 106, No. 49. (08 February 2009), pp. 20610-20615,


We examine the evidence for the possibility that 21st-century climate change may cause a large-scale “dieback” or degradation of Amazonian rainforest. We employ a new framework for evaluating the rainfall regime of tropical forests and from this deduce precipitation-based boundaries for current forest viability. We then examine climate simulations by 19 global climate models (GCMs) in this context and find that most tend to underestimate current rainfall. GCMs also vary greatly in their projections of future climate change in Amazonia. We ...


Comparison of uncertainties in carbon sequestration estimates for a tropical and a temperate forest

Forest Ecology and Management, Vol. 256, No. 3. (July 2008), pp. 237-245,


We compare uncertainty through sensitivity and uncertainty analyses of the modelling framework CO2FIX V.2. We apply the analyses to a Central European managed Norway spruce stand and a secondary tropical forest in Central America. Based on literature and experience we use three standard groups to express uncertainty in the input parameters: 5%, 10% and 20%. Sensitivity analyses show that parameters exhibiting highest influence on carbon sequestration are carbon content, wood density and current annual increment of stems. Three main conclusions arise ...
