Posted on 2013/01/08 by nakane

River Water Quality and Landscape in the Kumena and Tatau Basins, Sarawak, Malaysia Keitaro Fukushima 　(Field Science Education and Research Center, Kyoto University) 　River water quality is a very useful indicator of upstream terrestrial environment including land use, geology, lifestyle, development of infrastructure, and so forth. For example, the concentrations of calcium (Ca2+), magnesium (Mg2+) ions and dissolved silica (Si) are mainly controlled by underlying bedrock geology; nitrogen (N) and phosphorus (P) concentratios reflect land use such as agriculture and urbanization; and chloride ion (Cl–) concentration is likely proportional to the distance from the sea. Mines, factories, and livestock facilities can discharge high concentrations of N, P, certain metals, and […]

Developing a plant-survey method at Anap-Muput Forest Management Unit　[Miyako Koizumi]

Posted on 2012/06/27 by nakane

Developing a plant-survey method at Anap-Muput Forest Management Unit Miyako Koizumi　（Research Institute for Humanity and Nature）　There is global concern over sustainable development and mechanisms to provide incentives for the sustainable use of forests. There are two major problems in the development of such mechanisms. One is the economical problem of who and how to share costs and benefits. The other is the biological problem of how to evaluate ecosystems. The latter is considered highly challenging in tropical rainforests, where biodiversity is very high. 　Biodiversity studies in tropical rainforests have been conducted by specialists, sometimes with the help of para-taxonomists. Their study sites are relatively small, usually less than 1 […]

A report on joint research in Sarawak: the possibilities for study of ethnic Chinese by researchers and scholars from different fields [Tetsu Ichikawa]

A report on joint research in Sarawak: the possibilities for study of ethnic Chinese by researchers and scholars from different fields Tetsu Ichikawa（College of Tourism, Rikkyo University）　My study in Sarawak mainly focuses on the ethnic Chinese groups in that area. I have conducted the research, paying attention to the interactions between the ethnic Chinese and indigenous people in Sarawak. The interactions include business, mixed marriage, adoption and so forth. From the perspective of research experience in Sarawak, I would like to elucidate some of the characteristics of the research, performed by a team of researchers that integrate the humanities and science. 　The major benefit for me to take part […]
