KUALA LUMPUR 鈥 A rise in huge, opaque infrastructure and mining projects threatens to destroy and open up the world鈥檚 last remaining rainforests to development, researchers warned on Thursday.

A report assessing progress on the 2014 New York Declaration on Forests鈥攂acked by more than 200 countries, companies and green groups鈥攆ound that its 2020 goal to reduce natural forest loss by at least half would not be met.

Achieving its 2030 target to end deforestation would require an 鈥渦nprecedented鈥 reduction in the rate of forest loss, said the annual evaluation, led by advisory firm Climate Focus.

Berlin-based executive director Franziska Haupt, the report鈥檚 lead author, warned remaining forest areas 鈥渁re under severe threat from infrastructure and mining developments.鈥

鈥淓conomic corridors cut through these remaining areas, kettling in the indigenous communities and others that live there,鈥 Ms. Haupt told the Thomson Reuters Foundation.

In 2019, tropical rainforests鈥攚hose preservation is considered crucial to limiting planetary heating鈥攄isappeared at a rate of one football pitch every six seconds, according to data from online monitoring service Global Forest Watch.

Green groups blame the production of commodities and minerals for much of the destruction, as carbon-storing forests are cleared for plantations, ranches, farms, and mines.

鈥淢ining and infrastructure obviously has a direct impact鈥攊f you build a road or have an open-pit mine you have to cut trees,鈥 said Ms. Haupt.

鈥淭he problem is not so much that deforestation, but it鈥檚 that these activities are making way for other economic activities and resource extraction.鈥

ROAD TO NOWHERE
Megaprojects based around economic corridors, linking roads, waterways, and railways with natural resource extraction and big dams, are planned in most critical tropical-forest areas, said the report, produced with 22 organizations.

Across five Amazon nations鈥擝olivia, Brazil, Colombia, Peru, and Ecuador鈥攊nvestments totaling $27 billion over the next five years would construct or update more than 12,000 km (7,456 miles) of roads, it said.

If all planned projects are realized, they will cause the deforestation of about 2.4 million hectares (5.9 million acres) over the next two decades, it added.

In Asia, Indonesia鈥檚 Trans Papua highway鈥攁 4,000 km network鈥攚ill cut through Lorentz National Park, a World Heritage site, increasing access to more than 50,000 hectares of mining concessions inside the park, the report said.

A railway planned for Indonesia鈥檚 forest-rich Kalimantan region will open areas for coal mining and palm oil production, it said, while neighboring Papua New Guinea is looking to double its road network by late 2022.

The unchecked rise in transportation networks is poised to do the most damage to forests, the report said.

Those networks make it easier for loggers, farmers, and others who chop down trees legally or illegally to get into forests, according to researchers.

Roads are responsible for between 9% and 17% of tropical and sub-tropical deforestation, with most new deforestation occurring within 1 km of a road, said the report.

Ms. Haupt said infrastructure was essential for economic development, especially in places without basic services.

鈥淭here needs to be roads and there is always a cost for forests but we鈥檙e really concerned about these huge projects,鈥 she added.

BELT AND ROAD
The scale of many megaprojects was unprecedented, she said, citing China鈥檚 Belt and Road Initiative to link Asia to Europe and beyond, involving more than 100 countries.

Researchers found no evidence that megaprojects, which often lack transparency, are paired with investments in local development, such as public services, healthcare, and jobs.

Governments should consider the value of forests and the economic benefits megaprojects bring to local people鈥攁nd ensure they are properly consulted, said Ms. Haupt.

All countries need to develop partnerships to protect forests, and wean their industries off fossil fuels, she said, adding many had made international pledges and introduced good policies but implementation was lacking.

鈥淚t鈥檚 not a radical idea to strive towards sustainable development but the current (economic) models are in contention with these goals,鈥 she said. 鈥淚s deforestation really justified by these other benefits?鈥澛 鈥 Michael Taylor/Thomson Reuters Foundation
