JIRCAS International Workshop: Carbon sequestration in soils through farm land management - The latest world researches and relevancy in Southeast Asia - was co-organized by JIRCAS, Department of Agriculture (DOA) and Land Development Department (LDD), Thailand on 6 December 2012 at Bangkok, Thailand. 55 participants mostly from Thailand, Indonesia and Vietnam discussed the relevancy of carbon sequestration in farm land of Southeast Asia
In the opening session, after the welcome addresses by Ms. Bhavana Likhananont, Senior Expert on Soil and Fertilizer, DOA and Ms. Nongkran Maneewon, Expert on Acid Sulfate Soil Improvement, LDD, and the opening address by Dr. Tomoyuki Kawashima, Program Director, JIRCAS, Mr. Tomohide Sugino, Regional Research Coordinator for Southeast Asia, JIRCAS explained the background of the workshop.
In the morning session (Chair: Ms. Bhavana Likhananont, Senior Expert on Soil and Fertilizer, DOA), three keynote speeches were delivered: Dr. Yasuhito Shirato, Senior Researcher of Natural Resources Inventory Center, National Institute for Agro-Environmental Sciences (NIAES), Japan presented “Simulating changes in soil carbon in Japanese agricultural land by the Rothamsted carbon model”, Dr. Andrew Macdonald, Soil Scientist & Agronomist, Department of Sustainable Soils and Grassland Systems, Rothamsted Research, UK presented “Soil Carbon Sequestration: Lessons from the Rothamsted Long-term Experiments”, and Dr. Roland Joseph Buresh, Principal Scientist, International Rice Research Institute (IRRI) presented “An update on soil carbon sequestration and long-term soil experiments at the International Rice Research Institute (IRRI)”.
In the afternoon session (Chair: Dr. Sathaporn Jaiarree, Director, Research and Development for Degraded Soil Management, LDD), three country reports were presented by the national experts who have been implementing long term soil experiments under the JIRCAS collaborative project “Development of agricultural technologies in developing countries to respond to climate change”.
Mr. Suwandi, Researcher, Indonesian Vegetable Research Institute presented “Long-term experiments on farm land management in relation to carbon sequestration in the highland soil of Lembang, Indonesia”, Dr. Suphakarn Luanmanee, Researcher, Nakhon Sawan Field Crop Research Center, DOA, Thailand, presented “Long-Term Soil Experiment (LTSE) in Thailand under JIRCAS Research Collaboration”, and Dr. Luu Hong Man, Deputy Director, Cuu Long Delta Rice Research Institute (CLRRI), Vietnam and Mr. Takeshi Watanabe, Senior Researcher, JIRCAS presented “Long-term experiment for sustainable soil fertility management in the Mekong Delta Vietnam”.
The general discussion (Chair: Dr. Kazunobu Toriyama, Director, Crop, Livestock and Environment Division, JIRCAS) was concluded by acknowledging the importance of long term soil experiments and necessity to share and utilize the experiment outputs as common resources among the researchers. The role of soil organic carbon (SOC) to increase land productivity was also discussed. Though SOC is a critical factor in the low fertile area like Northeast Thailand, the holistic approach which focuses not only carbon but the other factors relating to the plant productivity is useful.
The workshop promoted the information exchange among the researchers in this field and successfully provided the latest achievements in soil carbon sequestration studies and long term soil experiments.
