Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored Article published by Glenn Scherer Amazon Biodiversity, Amazon Conservation, Amazon Dams, Amazon Destruction, Amazon Mining, Biodiversity, Biodiversity Crisis, Biodiversity Hotspots, Dams, Deforestation, DNA, Drivers Of Deforestation, Energy, Energy Politics, Environment, Environmental Politics, Flooding, Forests, Green, Hydroelectric Power, Hydropower, Infrastructure, Land Use Change, Mining, Monitoring, Rainforest Deforestation, Rainforest Destruction, Rainforest Mining, Rainforests, Rivers, Roads, satellite data, Satellite Imagery, Saving The Amazon, Threats To The Amazon, Tropical Deforestation In a new paper, scientists assert that environmental impact assessments (EIAs) for major Brazilian Amazon infrastructure projects often fail in their performance of comprehensive biodiversity evaluations, so underestimate ecosystem risk.Their proposed solution is the development and use within EIAs of multiple, complementary scientific methods they say would be cost effective, and make more comprehensive biodiversity assessments possible.These methods include satellite imaging, near-infrared reflectance spectroscopy, and DNA metabarcoding to detect a wider range of species. The scientists propose these methods be implemented to improve pre-construction biodiversity surveys and EIAs.A major concern by researchers is that Brazil’s Congress is currently considering legislation that would do away with the existing environmental licensing process, and reduce or eliminate existing EIA requirements. Looking up into the canopy of the Amazon rainforest. Numerous major infrastructure projects are under construction or planned for the Amazon basin. A new study examining the Environmental Impact Assessment (EIA) process for three very large such projects found their EIAs, as conducted, to be inadequate for evaluating biodiversity impacts. Photo by Rhett A. Butler / MongabayMany dozens of major infrastructure projects — including highways, dams and mines — have been given the green light in the Brazilian Amazon in recent years, and hundreds more are in the pipeline – but how well do their Environmental Impact Assessments (EIAs) perform? Are their projections of harm accurate, and do they sufficiently manage risk?Many projects, such as the Tapajós dam complex, have hit the headlines due to their projected social and ecological impacts, which include deforestation, harm to aquatic and terrestrial species, disruption to flood and nutrient cycles, increased carbon emissions, the flooding of sacred lands and the forced relocation of river communities.As a guard against these threats, all major development in the Brazilian Amazon requires that an environmental impact assessment (EIA) be carried out as part of the project licensing process. But a recent paper, examining three large infrastructure projects in the region, has found just how ineffective the existing EIA process can be.As a result, the scientists behind the study are calling for the incorporation of new technology into Brazilian EIAs to more accurately measure biodiversity and habitat quality ahead of construction, allowing a full cost-benefit analysis of development to be carried out.The BR-319 highway, linking the cities of Manaus and Porto Velho, was one of three major Amazon projects examined by scientists. Repaving the highway would open up biologically important areas of remote forest to deforestation, they say, something not adequately taken into account in the project’s EIA. Photo by Agencia CNT de Noticias under a Creative Commons Attribution 2.0 Generic licenseInadequate EIAsThe research team, led by Camila Ritter of the University of Gothenburg, Sweden, looked at an existing highway, hydropower dam, and mine:Paving the BR-319: This Amazon rainforest highway links the cities of Manaus and Porto Velho. Constructed in the 1970s, it fell into disrepair by the late 1980s. An EIA for paving a large, central section was rejected in 2008, but maintenance work — which effectively permits the reconstruction of the BR-319, except for paving itself — was approved in 2016. Although in this case the EIA contributed to the project license being formally rejected (for now) the scientists argue that the assessment fell far short of accurately analyzing the environmental consequences of paving. The improved BR-319 would likely do extensive harm to a highly biodiverse region between the Madeira and Purus rivers, rich in endemic species. Amazon highways, the researchers note, are a key driver of deforestation, with once remote and now newly accessible roadside forests a prime target for exploitation.Building the Belo Monte dam: When fully operational, the Belo Monte dam on the Xingu River will be the third largest in the world with an 11,000 megawatt generating capacity. Dogged by controversy and licensing hold-ups, the reservoir was filled in December 2015. The scientists argue that its EIA overlooked the synergistic effects of the dam in combination with other hydropower dams within the watershed. The EIA, they say, failed to fully evaluate the disruption to natural flood cycles, the carbon emissions caused by the reservoir, and also underestimated the dam’s impetus for a rapid increase in the local human population, which impacted the surrounding forest and wildlife. The Belo Monte EIA “is descriptive rather than predictive, and it falls short of proposing mitigating actions,” said the researchers.The Juruti bauxite mine: In the case of the Juruti bauxite mine, an industrial complex that includes a mine, port and railway on the southern bank of the Amazon River in Pará state, the scientists found that biological sampling for its EIA was inadequate. Not only was biodiversity significantly underestimated, but rare, endemic species were likely to have been missed altogether. This is on top of the “significant and long-lasting environmental changes” that the development is likely to bring to the region.What all three projects share, the scientists say, is a failure in one of the main components of every good EIA: to properly assess biodiversity. “The most important aspect in the discussion of Brazilian Amazonia EIAs is that we need to obtain better estimates of biological diversity, which translate into better predictions of biological and ecological impacts of these large infrastructural projects,” says Ritter.Belo Monte dam under construction in 2015. Large dams obstruct the flow of sediments and nutrients from headwaters to lowland floodplains, disrupt natural flood cycles, impede animal movement and migration along river channels, and drive deforestation.

This could help improve predictive abilities of future EIAs; and this could be particularly true in areas where these data get to be combined with reliable on the ground information,” added Pettorelli, who was not involved in the study.A bauxite mine in Brazil. Open pit mining, if not properly managed, can pollute the water table, creeks and rivers, and no matter how managed, results in deforestation. Norsk Hydro ASA photo found on flickrDNA analysisOn the ground, it could be the soil itself that holds the key: the third method highlighted by Ritter’s team for improving EIA accuracy is DNA metabarcoding — the sequencing of DNA found in soil to identify species and build up a picture of the biodiversity in a local area. Not only does this method have the potential to identify plants, animals, and microorganisms within a particular habitat without needing individual specimens, it also lends itself to repeatable and comparable analysis of regions and impacts.Douglas Yu, of the University of East Anglia, UK, leads research into metabarcoding methods, and is a co-founder of UK-based NatureMetrics, a company providing metabarcoding services to land managers. He agrees that using multiple methods is the way forward: “I think combining these independent data sources could provide a real boost to informativeness. Earth Observation provides continuous coverage of the environment, and metabarcoding (and other genetic information) could help to interpret those remote images.”Scientific and political obstaclesBut hurdles remain before these methods become mainstream. “The most useful satellite data for biodiversity monitoring in Brazil are not systematically readily available for the moment,” explained Pettorelli. But more important challenges “are linked to capacity, specifically capacity to analyze the available satellite data in a meaningful way,” she said.A red howler monkey howling. According to the study, all three of the project EIAs examined failed to fully assess biodiversity. The scientists suggest that technological advances offer cost-effective ways to improve biodiversity evaluations in the EIA process, including satellite imagery and DNA metabarcoding of soil samples. Photo by Rhett A. Butler / MongabayFor metabarcoding, “[t]he main obstacle would be to build a good DNA sequence reference database of all — or as many as possible — organisms in Brazil and the Amazon,” Ritter said. But, in the meantime, a simplified approach could make use of metabarcoding data to measure and compare diversity without knowing the exact species, she explained.There is added urgency for this debate: the legislative framework that defines EIAs in Brazil is under attack from proposed legal amendments that “would essentially abolish environmental licensing by making the mere submission of an environmental impact statement an automatic approval to go ahead with construction of the project in question,” said Philip Fearnside, of the National Institute for Research in Amazonia, and co-author of the new study.Once proposed amendments gutting the environmental licensing process come up for a vote in Brazil’s Congress — something Fearnside says is likely to happen at any time — “their approval is hard to stop due to ruralist control,” he explained, referring to the bancada ruralista, the agribusiness and mining rural lobby that currently wields tremendous power in the legislature and the administration of President Michel Temer.“The battle is focused on keeping the regulations we have from being abolished,” he added.But, Fearnside still sees the adoption of cutting edge EIA data gathering methods as a real possibility. “Technological improvements such as these are much more easily incorporated than are changes that require legislation,” he said, noting that similar changes have been made numerous times in EIA methodology over the past 30 years.Ritter is also optimistic about Brazil’s ability to make these necessary improvements.“I believe it is indeed possible to combine societal progress and large infrastructural projects with a continued high biodiversity. The money is available, as are the scientific expertise and the methodological progress,” concludes Ritter. “What is lacking, I fear, is the will to make this happen.”Citation:Ritter, C.
