Indonesia dam builder refuses new study to assess impact on orangutans Hans Nicholas Jong A dam developer in Indonesia has rebuffed calls for an independent study to assess the impact of the project on the critically endangered Tapanuli orangutan. The species, numbering fewer than 800, is found only in the Batang Toru forest in Sumatra, which is also the site of a hydropower project that conservationists say threatens the survival of the great ape and livelihoods of local communities. The IUCN has led calls for an independent assessment, citing a litany of inaccurate and misleading claims stemming from the project developer’s various statements and publications. JAKARTA — Developers of a hydropower dam that threatens the only known habitat of a critically endangered orangutan say they will push on despite calls from the IUCN for an independent study into the impact of the project. Emmy Hafild, a senior adviser to project developer PT North Sumatra Hydro Energy (NSHE), said there were “already enough studies” on the ecosystem of the Batang Toru forest in Indonesia’s Sumatra Island, home to the Tapanuli orangutan (Pongo tapanuliensis). “The problem is that people are picking studies that fit [their agenda] to frame” the project as threatening the environment, she said. She added the best way to save the Tapanuli orangutan is to sustainably manage the ecosystem by involving all stakeholders, including companies operating in the area. Emmy’s remarks come in the wake of mounting calls from scientists, conservationists and environmental activists for the hydropower project to at least be halted pending an assessment of how it will affect the orangutans. The species, only described in 2017 but already considered the most threatened of the eight great apes, number fewer than 800, concentrated in an area of forest about the size of the Indonesian capital, Jakarta. The three known subpopulations of the ape are separated by the Batang Toru River, and scientists fear the hydropower project will cut off connectivity between the groups. The latest expression of concern has come from the IUCN, which repeated its earlier call for a moratorium on further construction to allow for a scientific study to be carried out by an independent party. “No robust studies have yet assessed the importance of the project site for retaining connectivity among the three subpopulations of the orangutan, nor how habitat loss and the infrastructure from the project would affect orangutans in that area,” the IUCN primate specialists’ section on great apes (SGA) said in a blog post. The IUCN SGA said the independent study would have to be comprehensive and cover at least four areas. The first is a genetic study to determine the pattern of genetic diversity among the orangutan populations living on either side of the Batang Toru River, and how this would be affected by dam infrastructure. The second is a genetic study to determine recent population trends and whether the Tapanuli orangutan had until recently a much larger range. Third is improving estimates of the number of orangutans in all three known subpopulations. And finally, the study would have to quantify the various threats to the orangutans, such as habitat loss and killing. To protect or not to protect The dam project and a nearby gold mine are authorized in this part of the Batang Toru forest because the area, although forested, has been designated for conversion under government zoning plans. In 2014, extensive parts of the forest were redesignated as protected area, but not the site of the hydropower project, which was also eligible for protection but had already begun to be developed. The IUCN SGA says the site should be redesignated as protected as a means of providing greater protection to the Tapanuli orangutan. “Incorporating the whole non-protected area of which the project area is part into the protected forests of Batang Toru would add further security to the region’s wildlife and vital environmental services,” it said in the blog. To that end, a scientific study will allow for an unbiased assessment of whether the area truly warrants protected status, and whether projects and economic activities in the area should be relocated to avoid further degradation of the ecosystem, the IUCN SGA says. But NSHE adviser Emmy says such a study could have the opposite outcome — determining that the area 1 von 7 21.08.2020, 14:15 Indonesia dam builder refuses new study to assess impact on orangutans https://news.mongabay.com/2020/08/indonesia-hydropower-dam-tapan... doesn’t warrant protection — and thus open the window for more economic activities in the area. “It will reveal and provide opportunities for interests other than the necessity to protect the orangutan,” she said. “In reality, this is not a scientific, but a political process that goes beyond the control of both NGOs and scientists, especially scientists from overseas. The outcome is unpredictable and the level of uncertainty is high, since the district heads and local councilors tend to resist any changes to the existing land status that they fought so hard for in the past.” Emmy said lobbying the government to change the area’s status into protected forest would take a long time, and that that time would be better spent devising measures to protect the orangutan and its habitat. She added that’s why NSHE had established a consortium with the Swiss-based NGO PanEco in 2019 to cooperate on protecting the orangutan. PanEco initially described the dam as “the greatest threat to the long-term future of the Tapanuli orangutan.” But it toned down its criticism after a reported visit from intelligence officers and a reminder from Emmy that it faced having its permit to work in Indonesia terminated if its staff continued to criticize the dam. Emmy has previously denied threatening the NGO. “We should focus on [sustainable management], not go back to the process [of converting the area’s status],” she said. “This will help the orangutan to survive much more than going back from the start” to change the status of the area.

Misleading claims Serge Wich, the co-vice chair of the IUCN SGA and one of the scientists involved in describing the Tapanuli orangutan, said just the fact that the area is the habitat of a critically endangered great ape species should be reason enough to halt all economic activities there. “I would argue that in an area of a critically endangered great ape it can be highly risky to have economic activity that impacts the area,” he told Mongabay. “That is also why ‘avoidance’ of projects is always the first step in the mitigation hierarchy.” There are also a litany of uncertainties and unanswered questions regarding the potential impact of the dam and its associated road, earthworks and power line infrastructure on the Tapanuli orangutan, Wich added. These stem from many contradictory claims made about the project’s potential impacts, which were analyzed in a recent fact-check report by the IUCN. The report identifies several significant claims in NSHE’s publications or press releases as being inaccurate or misleading. 2 von 7 21.08.2020, 14:15 Indonesia dam builder refuses new study to assess impact on orangutans https://news.mongabay.com/2020/08/indonesia-hydropower-dam-tapan... “In at least ten cases, assertions made in public-facing NSHE literature or on the NSHE website are found to be inconsistent with findings presented in earlier impact assessments conducted on behalf of NSHE,” the report says. One of the biggest misconceptions about the dam project is that because an area is not protected, it is therefore not forested and not important for orangutans. That’s false, says Wich, who points out that non- protected status is a zoning designation that doesn’t indicate whether the land is forested or not. The IUCN report cites NSHE’s own environmental, social and health impact assessment (ESHIA), which says “the majority of the project area has been mapped as the land class ‘primary forest’ … followed by secondary forest.” And in 2018, the Indonesian environment ministry’s director-general for conservation, WIratno, said that despite the area’s non-protected status, “the forest cover is still intact.” Wich said a careful independent assessment of the likely impacts needs to be conducted before deciding how, or even whether, to continue with the project. “In conservation we should follow the precautionary principle and not develop something of which we do not know the impact,” he said. And now is the perfect time to do so as the work on the hydropower plant has already been put on hold since January due to pandemic-related health concerns, the IUCN SGA said in the blogpost. An official with the state utility overseeing the project said in July that the project could potentially be delayed by three years due to environmental, funding, and pandemic-related concerns. “The current delays might be an opportunity for the Indonesian government to propose alternative plans for the Batang Toru area — a life after the dam,” the IUCN said in its blog post. “The most threatened great ape species in the world deserves the highest level of protection. Cancelling the hydropower plans and moving the project, or an alternative option to generate energy, to another, lower-risk location, would show the world that Indonesia takes its international sustainability commitments and national environmental legislation seriously.” The Batang Toru River, the proposed power source for a Chinese-funded hydroelectric dam.
