    Accumulation and distribution of some heavy metals in water, soil and rice fields along the Pradu and Phi Lok Canals, Samut Songkhram Province, Thailand
    (2011-04) Roongrawee Kingsawat; Raywadee Roachanakanan; Raywadee Roachanakanan; Mahidol University. Faculty of Environment and Natural Resource Studies
    This study aims to determine concentrations of heavy metals (Cd, Cu, and Zn) in the water, soil, and rice in paddy fields, and to compare heavy metal concentrations in the water, soil, and four parts of the rice plant (root, shoot, grain, and husk...) between organic paddy fields and conventional paddy fields. The study area was the Pradu Canal (sites A and C) and the Phi Lok Canal (site B) in Phraek Nam Daeng Sub-district, Samut Songkhram Province, Thailand. Data was collected from August 2007

    and Abatement cost) while still maintaining an acceptable rice yield. To do so, methane (CH4) and nitrous oxide (N2O) emissions, and grain yields from rice fields were explored, under different farmer fertilizer application methods and two different crop... establishment options currently practiced by local farmers, namely transplanted rice (TPR) and wet bed direct seeded rice (WDSR). Both were measured in field experiments. In this study, it was found that rice cultivation emitted CH4 and N2O at the rate of 3.23±0

    was used as the basis for detection and quantitation by culture of B. pseudomallei in soil in two environmental sites (disused land covered with low-lying scrub and rice field) in northeast Thailand. Semivariogram and indicator semivariogram were used... to evaluate the distribution of B. pseudomallei and its relationship with range between sampling points. B. pseudomallei was present on culture of 80/100 sampling points taken from the disused land and 28/100 sampling points from the rice field. The median B

    Effect of population dynamics and mechanization on agricultural land use: evidence from Nang Rong, Thailand

    ,255 households. The results show that population dynamics continuously influenced agricultural land use. Migration was the most influencing factor among population dynamic indicators; it had negative effects on land use for rice and field crops, but positive... effects on multiple and rotation crops. Death events had some negative effects on land use for field crops, while in-migration had positive effects on rice growing. Agricultural machinery factors produced a great influence on land use changes both in terms

    Methane and Nitrous Oxide Emissions from Lowland Rice as Affected by Farmers’ Adopted Fertilizer Applications under Two Crop Establishment Methods in Myanmar
    (2022) Myo Thet Tin; Amnat Chidthaisong; Nathsuda Pumijumnong; Noppol Arunrat; Monthira Yuttitham
    ) emissions and rice yields under different fertilizer application methods and two different planting methods, transplanted rice (TPR) and wet bed direct seeded rice (WDSR), was measured. Field experiments using a split plot design and closed chamber-GC method...Identifying the optimal rice establishment option combined with specific fertilizer application can lower the global warming potential (GWP) and greenhouse gases intensity (GHGI) of rice production. In this study, methane (CH4) and nitric oxide (N2O

    Assessment of the Potential Climate Change on Rice Yield in Lower Ayeyarwady Delta of Myanmar Using EPIC Model
    (2018) Naw Mar Lar; Noppol Arunrat; Soe Tint; Nathsuda Pumijumnong; Mahidol University. Faculty of Environment and Resource Studies
    Climate change has been occurring and its consequences are a threat to rice production and hence food security. In this study, the effect of climate change on rice yield has been assessed by using the Environmental Policy Integrated Climate model... under climate change scenarios RCP4.5 (medium emissions) and RCP8.5 (high emissions) and to propose alternative adaptive measures for farmers’ livelihoods in the lower Ayeyarwady Delta. The results show that the average yield increase of early rice

    Asian openbill stork Anastomus oscitans as a predator of the invasive alien gastropod Pomacea canaliculata in Thailand
    (2012) Weerachon Sawangproh; Round, Philip D.; Pilai Poonswad; Mahidol University. Kanchanaburi Campus. Program in Conservation Biology.; Mahidol University. Faculty of Science. Department of Biology.; Mahidol University. Faculty of Science. Department of Microbiology.
    The freshwater golden apple snail Pomacea canaliculata, native to South and Central America, and the West Indies, is now a major agricultural pest in Thailand paddy fields. There is anecdotal evidence that the Asian openbill Anastomus oscitans... consumes these snails, but no reports on its predation efficiency. Our study showed that the number of storks visiting the fields correlated with a decrease in snail abundance (rs= 0.902, p= 0.0001). Storks are tactile predators and preferred adult
