The scope of unmanned aerial vehicles (UAVs), also known as “drone technology,” is increasing, with various applications in the field of remote sensing and environment. UAVs not only provide high-resolution, real-time data but also have different applications for end users. They have become an essential tool for land surveyors because traditional...

Environmental Science and Policy所収
Despite increasing scientific understanding of the global environmental crisis, we struggle to adopt the policies science suggests would be effective. One of the reasons for that is the lack of inclusive engagement and dialogue among a wide range of different actors. Furthermore, there is a lack of consideration of differences between languages...

Just a few decades ago, Adyar River in India’s city of Chennai was an important source of water for various uses. Due to local and global changes (e.g., population growth and climate change), its ecosystem and overall water quality, including its aesthetic value, has deteriorated, and the water has become unsuitable for commercial uses. Adverse...

Anthropogenic Tropical Forests: Human–Nature Interfaces on the Plantation Frontier所収
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...

Anthropogenic Tropical Forests: Human–Nature Interfaces on the Plantation Frontier所収
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...

Southeast Asian countries have been important suppliers of tropical timber to Japan since the early twentieth century. This chapter begins with a comparative examination of the history of the timber trade in the Philippines, Malaysia (Sabah and Sarawak), Indonesia and Papua New Guinea, for whom Japan has historically been the major market for round...

Anthropogenic Tropical Forests: Human–Nature Interfaces on the Plantation Frontier所収
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...

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...
