平成29 年5 月に「合法伐採木材等の流通及び利用の促進に関する法律」(通称「クリーンウッド法」)が施行された。また、平成29 年11 月から、同法に基づく木材関連事業者の登録が開始された。 このような背景の中、木材関連事業者による木材等の合法性確認等の取組を一層推進するため、本事業が実施された。本事業の目的は、木材関連事業者が効率的に木材等の合法性確認等の取組を実施できるよう、生産国における木材の流通や関連法令に関する情報を収集することである。 調査対象国は、パプアニューギニア、ソロモン諸島、ロシア、ベトナム、中国の計5カ国であり、それぞれの国において木材流通状況、関連法令・許認可制度、その他参考情報等が収集された。

Although it is widely acknowledged that forests provide critical ecosystem services for human survival and well-being, in the Asia-Pacific region forests are being converted to other land uses and degraded at alarming rates. One underlying factor for this destruction of forests is market failure. Forests are cleared for other land uses or degraded...

With rapid deforestation and forest degradation ongoing in tropical regions, the maintenance of biodiversity and high biomass/carbon stocks can bring additional benefits to the sustainable management of natural forests along with sustainable timber production. However, the measures for improving the maintenance of biodiversity and high biomass are...

The drastic transformation in land use from natural forest to acacia and oil palm plantations in tropical regions is an issue of some controversy. The influence of land-use change on nutrient cycling is not fully understood. In this case, stream water chemistry is one of the most useful indexes of the nutrient status of an ecosystem. We...

It is important to understand carbon (C) dynamics in terrestrial and coastal ecosystems in order to develop a strategy to control carbon dioxide effluxes. However, the factors determining concentrations of riverine carbon are still largely unknown, especially in Southeast Asia. We investigated the spatial distribution of dissolved and particulate...

Over the last few decades, the landscape of Borneo has drastically changed from primary forests to a mosaic of secondary forests and crop plantations, and more recently to the monocultures of single crop plantations. At the same time, livelihoods have become more linked to urban economies. To evaluate the effects of these changes on hunting...

In the traditional agricultural land-use pattern of the indigenous peoples of inland Sarawak, there are small areas of primary forests, referred to as a pulau or communally reserved forests (CRFs), which are customarily reserved by local communities. Here, we investigate the current condition and geographic distribution of CRFs in the human...

Rapid development in Bintulu has resulted in large-scale changes in land use, especially the conversion of forests into oil palm plantations and industrial tree plantations. Using high-resolution satellite imagery, we analysed land-cover types in the Kemena–Tubau–Lower Jelalong region of Sebauh subdistrict and classified them into nine major land...

This chapter discusses the historical formation and current features of society in the Kemena and Tatau river basins in Bintulu, central Sarawak, where various ethnic groups live close together in a small area as a result of the historical migration of each group. We refer to previous studies and to interviews we conducted, mainly in 2011...

While Borneo is a global biodiversity hotspot, its species-rich natural rainforests have been degraded and deforested in the past few decades by unsustainable shifting agriculture, commercial logging and the rapid development of industrial tree and oil palm plantations. Populations of some wildlife species have decreased drastically due to...
