  • Coastal Geomorphic Response to Future Sea-level Rice and Its Implication for the Low-lying Areas of Bangkok Metropolis

    Evidences on the relative sea-level rise in a tidal mangrove areas of this shoreline are useful to compile the measured and assumed rates of sea-level rise over the land for predicted conditions in the future and to compare the charts indicating the movements of the local sea-level change in the historical trend. In the low-lying areas of Bangkok Metropolis, an increase in sea-level of at least 1m is accepted for the next 100 years due to the warming effect of present super-interglacial. The most serious current problem of Bangkok now is related to the excessive exploitation of groundwater which has resulted in wide-scale subsidence and groundwater contamination. In the Bangkok metropolis areas, a combination of subsidence and sea-level rise will seriously affect residential area, pollution of surface water and groundwater, flooding, wastewater drainage and treatment, agricultural land, and industrial and commercial activities in the foreseeable future.

  • Lac Cultivation and Host Tree Plantation in Northern Thailand

    The technique of lac cultivation in northern Thailand, including breeding of the lac insect (Laccifer lacca) and management of host tree plantations, are described. The historical changes in tree species used as host are also discussed.
     Traditionally, lac was cultivated on wild host trees. Since the introduction of the rain tree (Samanea saman) at the beginning of this century, lac has been cultivated in host tree plantations. Today, most local people believe the rain tree to be indigenous, as it has spread so widely as a host tree over northern Thailand.
     Lac cultivation, host tree plantation and rice cultivation are combined into an agro-forestry system in the farm household economy. In this system, the farmer engages in lac cultivation in the agricultural off-season to earn cash income in the short term. In the long term, the unstable income from rice production is supplemented by selling old host trees. Lac cultivation and agriculture thus complement each other.
     With the increasing demand for seedlac on the world market, Thailand has become one of the world's leading lac producing countries since World War II. With the boost of lac production, rain tree plantations have increased. Nowadays, these plantations are a very important source of timber for the local market. The rain tree plantation can be considered as an “endogenous forest plantation” in Thailand.

  • A Re-examination of Raffles's Statistics on the Population of Java in the Early Nineteenth Century:
    Some Problems of Early Censuses

    This paper focuses on the re-examination of the Raffles's population statistics of Java in early nineteenth century. Population statistics of these early periods have been either cited uncritically or simply abandoned as unreliable. The defects of these old statistics should be discussed explicitly before they are treated in either way. The figures compiled by Raffles in his History of Java were based on the reports by the local colonial officers and/or native rulers in Java. Underestimation in the statistics is due to a. oversight of certain regions, b. underestimation of household numbers, c. underestimation of household members. A considerable part of the underestimation derives from that of household members. In this paper, a detailed examination was done of the following aspects: a. errors in computation, b. distribution of household size by sub-district, c. distribution of sex-ratio by subdistrict, d. variation of age-structure by subdistrict, e. problems of Chinese population. Special attention was given to the consistency of the definition of categories and the distribution patterns of the reported figures. Various aspects of underestimation may reflect the opposing interests of colonial officers vs. native rulers, and rulers in general vs. the ruled. The diverse distribution of the statistical index figures seems to be a result of a balancing of these elements in diverse situations.

  • Changes in the Swidden System of the Kenyah Dayak Tribe

    Since the 1950s, the Kenyah Dayak people have been moving out of their isolated home. The further they migrate downstream, the more the monetary economy infiltrates into the village. At the same time, social and economic structures such as work organization, the mutual aid system, and the traditional land tenure system change. As the result of such changes, the originally sustainable swidden system has changed to a less sustainable one.
     To examine the dynamics of the swidden system practiced by the Kenyah people, the infiltration of monetary economy and the effect of the system on the environment are adopted as parameters.
