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...

The biodiversity of stream-dwelling fish and the effects of oil palm and acacia plantations on this biodiversity were evaluated by field research conducted in the Bintulu region of central Sarawak, Malaysia. A quantitative survey was conducted at 61 locations by electrofishing. These 61 locations included 16 sites in oil palm plantations, five...

The Anap Muput Forest Management Unit (AMFMU) located in Bintulu, Sarawak, Malaysia is a production forest. It have undergone at least one or two cycle of selective logging where valuable timber species are depleting. Therefore the structure, composition and productivity of the re growth forests are quite different from the virgin stands. Measuring...

Bornean Ferret Badger Melogale everetti is endemic to the uplands of the Mount Kinabalu and the Crocker Range, Sabah, north Borneo; it is currently categorized as Endangered on The IUCN Red List of Threatened Species. No systematic survey has been conducted and its ecology is largely unknown. To better understand the ecology of Bornean Ferret...

This paper describes the trans-river migration of the Iban and Bekatan to the Tatau River Basin in Bintulu Division, Sarawak. Until the beginning of the nineteenth century, the Iban and Bekatan did not inhabit the Tatau River Basin, but migrated there from other river basins from the middle of the nineteenth century onward. We describe the...

This is the summary of the country drought risk reduction assessment done as a part of the JICA-ASEAN project on integrating climate change adaptation and disaster risk reduction into institutional and policy processes (CN 20). There is heavy reliance of the government on drought relief leading to drought relief dependency among the farmers in...
