    ABSTRACT: The paper examines environmental management accounting as a tool that supports environmental investment decision-making in the context of the emerging markets for carbonised rice husk and the clean development mechanism. Based on a case study at Oliver Enterprises, a rice milling business in the Philippines, the paper analyses carbonisation and cogeneration as two processing alternatives to reduce environmental and social impacts related to the conventional way of rice husk disposal and to improve the overall performance of the rice mill. Implications for corporations and for policy decision-making are examined.

    ABSTRACT: Rice marketing margins are substantially greater in the Philippines than in Thailand despite many similarities between the two systems and despite the fact that Philippine rice marketing has a competitive structure. We found that rice marketing costs in the Philippines are higher than in Thailand mainly due to higher interest rates in the financial system. Other fundamental factors that also result in higher costs include endowments of water and land, rice price and trade policy, road quality and lack of non-farm job growth. However, the greater costs can only account for about a fourth of the difference in gross margins, implying much higher returns to management in the Philippines despite similar levels of risk and no evidence of collusion. The “excess profits” in the Philippine marketing system suggest there is much to learn about how developing country commodity markets with competitive structures function in actual practice.

    ABSTRACT: The flight activity of yellow stem borer Scirpophaga incertulas (Walker) (Lepidoptera: Pyralidae) peaked in the months of April-May, May-June, August-September and October. The number of egg masses and the number of adults attracted to light sources were the indicators of S. incertulas flight activity. The rice varieties TKM6, IR22, IR60, IR66 and IR74 were infested at 7, 10, 12 and 16 wk after planting with 5, 10, 20 and 40 neonates of S. incertulas. All varieties except IR66 were susceptible to dead heart damage by S. incertulas. When the rice varieties TKM6, BPIRi2, BPIRi4, IR22, IR36, IR60, IR66 and IR74 were treated with carbofuran insecticide at the time of peak oviposition by S. incertulas in the field, the dead heart damage on all the varieties was significantly reduced in comparison with the untreated plots. Indiscriminate routine insecticidal treatments (fixed schedule) can be replaced by a treat-when-necessary schedule based on the population dynamics of S. incertulas.
