Speech title "Sustainable Use and Zero Waste for Water Resources"

Abstract-The demand for water in both quantity and quality kept rising. As water is life, it is a need to have equitable manner that work in harmony with nature and respect to environmental quality of an immutable hydrological cycle. Environmental sustainability is complex needed integrated approach, coherence, innovation, and balance under space and time scale. Zero waste is a philosophy signified waste as a resource lead to developing technologies about turning the materials recovered from water used or waste water treatment system into new products provided similar environmental quality and/or benefits. The concept of using used water or recycled water to produce new products not only virtually eliminating the need for water consumption from natural resources but also need acceptance and interest of consumer to used and purchase. One of the best management practices (BMPs) in Thailand as a case study was presented by using agro-processing waste and by-product to be reused in direction of zero waste through innovations to reduce the impact of green-house gas emissions as well as generate innovations to enhance bio-energy recovery and provision of clean freshwater resources in entry point for sustainable use and zero waste for water resources.

Speech title "Integrated Economic Environment modelling based on the System of Environmental-Economic Accounting (SEEA) and policy analysis"

Abstract-More recently, the System of Environmental-Economic Accounting (SEEA), a satellite system of the SNA, has become an international statistical standard for analysing integrated policies on climate change/circular economy/SDGs issues and their interaction with the economy. Furthermore, in 2017, the United Nations Statistical Commission endorsed the SEEA as a supporting framework for the application of the SDGs to policy. Related previous studies have also attempted to assess SDG targets in Natural Capital Accounting and Integrated Economic Environment modelling. In this research, we attempted to apply a new SEEA based on the environmental extension of official statistics through monetary and physical hybrid accounts to IEEM modelling. According to the research question above, we have constructed SEEA-IEEM models using these SEEA accounts for SDGs policy analysis. We have systematically captured the flows from the environment. Simulations were carried out with changes in environmental factors and economic variables in several scenarios. Nowadays, SEEA is widely used to provide relevant policy information for policy issues such as circular economy, climate change and green growth. Regarding the novelty of the research, we believe that our research is one of the pioneering attempts by compiling SEEA composite accounts with Natural Capital and IEEM model for application to policy analysis including SDGs as described above, and hope that our research will contribute to the analysis for related integrated policies.

Speech title "Understanding the quality and potential of groundwater for human purposes and peat fire disaster mitigation"

Abstract-Issues related to groundwater sources in peat coastal areas are very complex. These include sea water intrusion and the quality of the groundwater itself. An additional issue is the source of water to extinguish peat fires. The study area of this research is located in the coastal zone of the Siak River delta, Indonesia. The coastal zone is covered mainly by peat soil, and it is vulnerable to fires in the peat during the dry season. This study investigates the potential of groundwater for preventing a peat fire disaster and for the possibility of domestic use in the community. Subsurface resistivity data were obtained by using 14 geoelectrical resistivity surveys with the Schlumberger configuration. Characteristics of the eight groundwater samples and 14 soil samples were analyzed. The resistivity of the peat soil ranges from 40 to 50 Ω-m, and the soil is distributed throughout the study area except the middle and east parts. Relative proportions of sand and gravel at various depths were observed through resistivity data. This zone is considered a potential aquifer. The water in the aquifer has a relatively high chloride content (63 to 1189 mg L−1). The brackish water in the aquifer is believed to be ancient seawater trapped in the aquifer during the sedimentation process in the geologic past. However, the groundwater in the study area is more than enough to mitigate a peat fire disaster in the entire study area.
