At the TREES lab, we are testing new technologies for improving our capacity to understand the past, present and future of the Amazon forest.
With a team from National Institute for Space Research, in Brazil and the University of Exeter in the UK we performed the first flights of the fix wing platform named NAURU 500B integrated with a LIDAR (Light Detection and Ranging) system (see images below). These flights were part of the project “Pre-Columbian Amazon-Scale Transformations (PAST)” led by Jose Iriarte from the University of Exeter.
For learning more about these Amazonian inhabitants, read the paper from Jonas Souza "Pre-Columbian earth-builders settled along the entire southern rim of the Amazon" published at Nature Communications (https://www.nature.com/articles/s41467-018-03510-7). Jona's paper is the 1st out of 1,067 tracked articles of a similar age in the journal!
Now, using these LIDAR point clouds from the UAV and also airplanes, we are investigating the spatial extent of earthworks in Amazonia. We hope to have interesting results soon!
A groudbreaking study shows that more carbon means more biodiversity in forests with a high degree of degradation, however, in forests with less human interference, increasing amounts of carbon may not be accompanied by more species.
Tropical forests are rich in carbon as well as biodiversity. As a result of climate and anthropogenic changes in tropical forests, there is an increase in the availability of financial resources for carbon protection in these ecosystems. Protecting carbon from tropical forests is a major goal of international climate change initiatives, drawing tens of billions of dollars in funding each year. However, one question still remains: Are these measures enough to promote the survival of species that inhabit these forests?
A study published yesterday in the renowned journal Nature Climate Change (https://www.nature.com/ articles /s41558-018-0225-7) suggests that the answer to this question is not so simple. The study was prepared by an international team of scientists from Brazil, Europe and Australia, including Embrapa Amazônia Oriental (leader of the study) and the National Institute of Space Research (INPE). The group found that investments to avoid carbon losses in tropical forests are likely to be less effective for the conservation of biodiversity in the forests of greater ecological value. To the researcher's surprise, in these forests (which are the most preserved), up to 77% of the species that would have been protected through actions aimed at biodiversity conservation would not be protected in the case of measures focused exclusively on the protection of carbon stocks.
"Protecting carbon stocks from tropical forests should remain a central goal in international conservation policies," says Joice Ferreira, one of the leaders of the study and researcher at Embrapa. "This type of measure can not only slow down climate change, but also has the potential to protect life if it is unique and irreplaceable in tropical forests like the Amazon. However, to ensure that such species survive, biodiversity needs to be treated as a central focus of conservation efforts - as well as carbon. "
Tropical forests store more than a third of the world's terrestrial carbon. Human-induced phenomena such as deforestation and degradation (logging, hunting, forest fires and forest fragmentation) can trigger the release of carbon and increase the effects of global climate change.
Luiz Aragão, a scientist at the Tropical Ecosystems and Environmental Sciences Laboratory (TREES - www.treeslab.org) of INPE's Remote Sensing Division, states that "this study proves the efforts of Brazilian scientists to better understand patterns and processes in tropical forests for supporting public policies for environmental conservation and promotion of sustainable development, such as the National Strategy for REDD + ". Aragão says that "the results of this research are part of a long-term collaboration between these scientists, who have already demonstrated the effects of forest degradation on biodiversity (https://www.nature.com/articles/nature18326 ) and on forest carbon emissions ( https://www.nature.com/articles/s41467-017-02771-y). "We have now been able to connect these two elements, essential for maintaining ecosystem services, carbon and biodiversity, in an analysis that provides support for strategic planning of actions for conservation of our forests", adds the scientist. Remote sensing techniques have already contributed to significant advances in our understanding and quantification of forest carbon, however, Aragão recognizes that "for promoting biodiversity protection there is still a long way to go in terms of development of remote sensing techniques". This development also depends on extensive field monitoring.
This study is critical for aligning carbon conservation with biodiversity efforts. Gareth Lennox, one of the study leaders and a scientist at the University of Lancaster, explains that "forests with the highest carbon content do not necessarily harbor more species, which means that conservation focused exclusively on carbon can leave aside rainforest areas that are quite biodiverse". However, the scientist of the Stockholm Environment Institute (SEI, its acronym in English), Sweden, Toby Gardner, one of the co-authors of scientific work, states that "by considering carbon and biodiversity together, we find, for example, that the number of large tree species that can be protected increases up to 15% over the carbon-exclusive approach. In contrast, in this same situation, there is only a 1% reduction of carbon stocks".
Reducing the effects of climate change requires the protection of biodiversity. Professor Jos Barlow of the University of Lancaster explains: "Biodiversity and climate change are intrinsically linked when we focus on rainforests. Warmer weather and changes in rainfall patterns will lead to the extinction of many tropical species and it is important to remember that forest carbon resides in the biodiversity of tropical forests. Poverty of species will inevitably result in carbon poverty. Addressing the climate crisis requires the protection of both simultaneously".
The scientific article, Ferreira et al. (2018), Carbon-focused conservation may fail to protect the most biodiverse tropical forests (Carbon-focused conservation may fail to protect the most biodiverse tropical forests), is available online in the journal Nature Climate Change ( DOI: 10.1038 / s41558-018-0225-7).

Brazil´s globally significant ecosystems could be exposed to mining and dams if proposals currently being debated by the Brazilian Congress go ahead, according to researchers publishing in the journal Science this week.
The new report by a group of Brazilian and British researchers comes in the wake of Brazil´s recent presidential elections. It warns that new legislation could pose a serious threat to protected areas, weakening Brazil’s international status as an environmental leader.
One of the proposals of particular concern is the call to open up 10% of the most strictly protected areas to mining. In a new analysis, the research shows that at least 20% of all Brazil´s most strictly protected areas and reserves for indigenous people overlap with areas that have been registered as under consideration for mining. In addition, many of the river systems associated with protected areas will be influenced by the construction of large hydroelectric dams.
The threat that this mining and hydropower poses to Brazil’s ecosystems is not trivial. Areas of registered interest for mining in Amazonia, for instance, include 34,117 km2 that are currently classified as strictly protected areas – including National Parks, Biological Reserves and Wildlife Refuges. This is equivalent to an area the size of Switzerland. The situation is worse for amazonian indigenous lands, 28% of which, or 281,443 km2, overlap with areas of registered mining interest – an area larger than the whole of the UK or the state of São Paulo.
In recent years Brazil has enjoyed increasing recognition as a world leader in combatting environmental destruction. Brazil´s protected area network is the largest in the world, while improved environmental governance in private lands has contributed to an 80% reduction in the rate of deforestation in the Brazilian Amazon over the last decade. Yet these new proposals could threaten these recent successes and undermine Brazil’s reputation.
Dr Joice Ferreira, a scientist at Brazil´s agricultural research institute, Embrapa, and lead author of the study, said: “The purpose of this analysis is not to say that Brazil´s development should not benefit from its abundant natural resources, but that we should not squander our hard-won record of success and leadership in favor of fast-tracked and poorly planned development projects that leave a long legacy of environmental damage. It is possible to manage our development in a more sustainable way.”
Co-author Dr Jos Barlow, a researcher at Lancaster University and a visiting professor in Brazil, said: “Rather than exploiting protected areas for short-term gains, Brazil should treasure them for the long-term benefits they can provide to society. The recent water shortages in the south east of Brazil emphasize the importance of protecting native vegetation across the country.”
The authors of the study also warn that the proposals for minimizing and mitigating the environmental damage of large-scale development projects are so inadequate that even if only a fraction of these mining concessions were approved then the impacts could be enormous, especially in Brazil´s most threatened ecosystems.
Dr. Luiz Aragão a co-author of the study from Brazil´s federal space agency, INPE and the University of Exeter said: “Our concern is that even if the proposed mitigation actions were put in place they are oversimplified because they fail to take account of the indirect effects of mega-projects.
“These projects can involve thousands of workers and lead to rapid local population growth. This, combined with new roads and access routes, is a recipe for the emergence of new deforestation frontiers.” explains Luiz.
The study highlights the fact that these worrying changes reflect an important shift in the support shown by Brazil´s federal government to environmental protection. These concerns come on the back of other recent changes, including the partial dismantling of Brazil´s protected area system to make way for development – with some 44,100 km2 lost since 2008 due to downsizing or abolishment - and the weakening of the Forest Code that gave an amnesty to landowners who deforested illegally in the past.
“Beyond the conservation and stewardship of its own biodiversity and environmental resources, so vital to the wellbeing of its citizens, Brazil plays a vital role in motivating and supporting the adoption of more sustainable development trajectories around the world,” said Toby Gardner, of Stockholm Environment Institute, one of the authors of the study who has worked in the country for more than a decade. “Yet this standing is now in jeopardy.”
Dr Joice Ferreira said: “The newly elected government has the chance to set the record straight and point Brazil firmly on a path of sustainable development. The authors of this report call on President Dilma and her government to ensure that individual development initiatives are subject to a comprehensive, socially inclusive, evidence-based and long-term cost-benefit analysis that compares potential environmental and social impacts against alternative development options. And also to ensure that Brazil´s renowned protected area network is given the resources it needs to manage our ecosystems sustainably.
“Above all we ask the Government to guarantee that important decisions regarding the management of Brazil´s natural resources involve the full and democratic participation of Brazilian society.”

De acordo com pesquisadores que publicam na revista Science desta semana, os ecossistemas do Brasil, de importância mundialmente reconhecida, podem estar ameaçados se propostas, para mineração em unidades de conservação e para o estabelecimento de hidrelétricas, atualmente em debate no Congresso Nacional, seguirem em frente.
O novo estudo de pesquisadores da EMBRAPA e do INPE, além de outros colaboradores brasileiros e britânicos é publicado logo após as eleições do Brasil. Ele adverte que as mudanças propostas podem representar uma séria ameaça para as áreas protegidas, enfraquecendo a posição internacional do Brasil como um líder ambiental.
Uma das propostas, que causa especial preocupação, consiste em um projeto de lei para abrir 10% das áreas de proteção integral à mineração. Em uma análise inédita, a pesquisa mostra que pelo menos 20% da área de todas as reservas estritamente protegidas e terras indígenas do Brasil coincidem com as áreas que foram oficialmente registradas como de interesse para a mineração. Além disso, muitos dos sistemas hídricos associados com áreas protegidas serão influenciados pela construção de grandes usinas hidrelétricas. A sobreposição entre áreas protegidas e interesse mineral ou hidrelétrico ocorre principalmente na Amazônia.
A ameaça que a mineração e usinas hidrelétricas representa para os ecossistemas do Brasil não pode ser desprezada. As áreas com interesse registrado para a mineração na Amazônia, por exemplo, perfazem 34.117 km2 das áreas atualmente classificadas como áreas de proteção integral - incluindo os Parques Nacionais , Reservas Biológicas e refúgios de vida silvestre. Isto é equivalente a uma área do tamanho da Suíça. A situação é pior para as terras indígenas amazônicas, das quais 28%, ou 281.443 km2 tem sobreposição com áreas de interesse de mineração registrado - uma área maior do que o Reino Unido ou o estado de São Paulo.
Nos últimos anos o Brasil tem tido um crescente reconhecimento como líder mundial no combate à destruição ambiental. O país tem a maior rede de áreas protegidas do mundo e avanços na governança ambiental, incluindo em terras privadas, tem contribuído para uma redução de 80% na taxa de desmatamento na Amazônia brasileira durante a última década. No entanto, essas novas propostas podem ameaçar esse sucesso e minar a reputação ambiental do Brasil.
A Dra. Joice Ferreira, pesquisadora da Embrapa e primeira autora do estudo, disse: "O propósito desta análise não é dizer que o Brasil não deve se desenvolver e beneficiar de seus recursos naturais abundantes, mas que não devemos ameaçar nossa reputação duramente conquistada de sucesso e liderança em favor de projetos de desenvolvimento pouco planejados que deixam um longo legado de danos ambientais. É possível gerenciar o nosso desenvolvimento de forma mais sustentável".
Dr. Luiz Aragão, coautor do estudo e pesquisador do INPE disse: "Nossa preocupação é que, mesmo se propostas de mitigação fossem efetivadas, estas tendem a ser muito simplistas porque não consideram os efeitos indiretos de mega-projetos. Esses projetos, normalmente, mobilizam milhares de trabalhadores e levam a um rápido crescimento da população local. Isto, combinado com novas estradas e vias de acesso é uma receita para o surgimento de novas fronteiras de desmatamento”.
A solução, segundo os autores do estudo, é inicialmente se conscientizar que a manutenção das funções ambientais, através da preservação de ecossistemas únicos, é parte do desenvolvimento e não um competidor. Segundo, é ter a garantia por parte dos tomadores de decisão que as iniciativas de desenvolvimento sejam sujeitas a uma análise técnica de custo-benefício, socialmente inclusiva e de longo prazo, baseada em evidências científicas que comparem os potenciais impactos ambientais e sociais contra opções alternativas de desenvolvimento, para garantir o cumprimento da Constituição Federal (Art. 225).
Os autores ressaltam que “este estudo é relevante para salientar que decisões importantes a respeito da gestão dos recursos naturais do Brasil devem ser feitas com a participação plena e democrática da sociedade brasileira".
