Conservation: Quantifying illegal logging in the Peruvian Amazon



今回、Matt Finerたちは、違法伐採に関連した違反行為の地理的スケールと種類についての解明を進めるため、ペルー政府のデータを解析した。その結果、監督機関によって監視された森林伐採権の68.3%に重大な違反行為の疑いがあり、発給された森林伐採権の約30%が違反行為のために取り消されていたことが判明した。違反行為の内容を調べたところ、法的に有効な森林伐採権に伴う許可証が、無許可区域での伐採に利用されていることが分かった。また、多くの違反行為は、絶滅の恐れのある野生動植物の種の国際取引に関する条約(ワシントン条約)に定める木材種の違法伐採を許可区域外で行うというものだった。


The policies designed to bolster sustainable logging practices in the Peruvian Amazon may in fact be contributing towards illegal logging in the region. The study, published in Scientific Reports this week, suggests that because logging is not contained within areas that have legal logging concessions in place, many forested areas, including protected areas and indigenous territories, remain threatened.

The US-Peru Trade Promotion Agreement, which came into force in 2009, contained an annex aimed at strengthening governance of Peru’s forests and promoting sustainable management of forest resources. Yet despite this and other efforts, illegal logging persists within the country.

Matt Finer and colleagues analysed Peruvian governmental data to better understand the geographical scale of and types of violation related to illegal logging. They found that 68.3% of all concessions overseen by supervisory bodies were suspected of major violations, and nearly 30% of concessions have been cancelled for violations. The nature of the violations indicates that permits associated with legal concessions are being used to harvest trees in unauthorized areas. Many of the violations relate to the illegal extraction of timber species listed in the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) treaty outside authorized areas.

The study suggests that further reforms may be needed to protect the threatened forested areas of the Peruvian Amazon.
