Title: Nature-based Solutions for Natural Disaster Risk Reduction - Revived from Old Wisdom of Traditional Ecological Practice-
Nature-based solutions (NBS) refers to the sustainable management and use of nature for tackling socio-environmental challenges such, focusing on water issues, as water security, flood protection, and water pollutions. Focusing especially on the fundamental facilities and systems necessary for the socio-economic activities of human society, the term could be interchangeably used with green infra, or blue-green infra.
Traditionally, people living in the East Asian region including Korea, Japan, and eastern part of China, which are affected by the East Asian monsoon climate, have used various ecological practice for making better living environment, protecting themselves against natural disasters, and more efficient use of natural resources for better yield. They include, among others, riparian forest belt in Korea, Beitang in China, and Satoyama in Japan. Many of those practice disappeared, however, since modern natural resources management practice of land, water, and forest have overshadowed, for efficiency, the traditional nature-based measures. Some of them, however, have been revived in their original forms or modified ones as our society puts its emphases on the conservation and restoration of nature and eventually on the nature-based measures on tackling societal issues including climate change issue.
An example of such in Korea is the old wisdom of planting trees for disaster risk reduction. The first type is planting trees on the earthen levees along the rivers to protect their villages and farmlands against river floods. The second type is planting trees along the coasts and beaches to protect them against storm surges as well as windstorms incurred from the sea. The third one is planting trees on the northwestern side of villages to protect their villages against the chilly northwestern winds in winter season. The first one was called anti-flood forest strip, the second was called anti-storm coastal forest strip, while the third was called anti-wind forest strips. All of them, which could be also found in other parts of the East Asian region, can be called modern-type green infras for disaster-risk reduction. Riparian buffer strip or zone, one of the well-introduced nature-based solutions on the water management practice as well as eco-corridor habitat provision, could be a good example of the revival of a traditional ecological practice in Korea. Likewise, modern-day constructed wetlands for water purification as well as aquatic habitat provision is another good example of the revival of Beitang in China.
In addition, the concept of so called ‘room-for-the-river’ could be also a nature-based solution for flood risk reduction in channelized rivers. In Korea, one of such examples would be utilization of a paddy field as washland. Here, washland means a semi-natural or artificial retention basin to accommodate excessive flood water from neighboring river.

Title: Coupled thermo-hydro-chemical and mechanical modeling of reservoir trasmissivity alteration and temperature drawdown
Geothermal energy extraction by cold water injection and hot water production disturbs the thermo-chemical equilibrium of a geothermal reservoir, activating the dissolution/precipitation of minerals in the fractures and porous rock matrix. The cooling also causes mechanical deformation of rock matrix and rock joints/fractures. These lead to alteration of hydraulic transmissivity. The dissolution/precipitation depends on minerals, rock type and injection conditions. 1/5th of the earth's surface is made of limestone. In that calcite (CaCO3) is over 90% of the bulk. Silica (SiO2) is one of the most abundant mineral (around 37% in upper earth crust). Amorphous silica is more reactive. There are two major differences in their solubility and reactivity. With temperature the solubility decreases and increases respectively for calcite and silica. The dissolution/precipitation of calcite is 103 – 104 times faster than silica. So the dissolution and precipitation patterns around injection and production wells are very different in carbonate and silicate reservoirs. Consequently the reservoir transmissivity evolves differently. The contraction due to cooling and swelling/contraction due to pore pressure result in significant change in trasnmissvity of fractured reservoir. We numerically simulated the effects of mineral dissolution/precipitation and thermo-poro-elastic deformation on temperature drawdown and pumping pressure change for a reservoir that consists of a single fracture connecting the injection and production wells. We predicted the alteration of fracture aperture by both thermo-hydro-chemical (THC) and thermo-hydro-mechanical (THM) effects during heat extraction by water circulation. The channeling of flow between injection and production wells by THM effects and dissolution of calcite causes faster temperature drawdown and reduces energy production. However the dissolution of silica occurs more away from the wells. So in this case injected water travels more before coming to production well. This increases the energy production rate. The precipitation of minerals increases the pumping pressure for maintaining the constant flow rate. So the operating cost will be more. We also modeled the possible hazard of ground surface displacement due to hydro-mechanical deformation of reservoir.

Title: Structure and toughness improvement of poly(lactic acid) blends
Biodegradable polymers have attracted a great deal of attention in decades owing to the environmental concern and sustainability issue. Among them, poly(lactic acid) (PLA) is the most used biodegradable polymer which is derived from renewable resources and considered as non-toxic for humans and the environment. However, it is well known that PLA is a brittle plastic with low resistance to fracture. In this presentation, I will talk about the research work in my group about the structure and toughening of PLA materials through blending with low-molecular-weight plasticizer, biodegradable polymer and organic-modified clay.

Title: Liveraging SDG for life in future: Current challenges and expectations in urbanisation
We believe in the advances of ideas, innovations and technologies the quality of life will be tremendously improved. More people will be migrating and leaving in urban areas to acquire such benefits and advantages. It is predicted that in year 2050, urban population will take around seventy percent (approximately seven billion) of the total world population. Such huge numbers of population will be a great challenge to urban managers, policy and decision makers, as well as the countries’ leaders. In 2015, the United Nation Member States have adopted seventeen Sustainable Development Goals (SDG) to be achieved in year 2030. The vision, target and hope are to improve quality of life (QoL) in all countries, and to a greater extend, to ensure liveability for their urban inhabitants. Liveraging SDG on the one hand can facilitate the needs to improve way of doing things, but on the other hand will be a great challenge to many people, organisations, institutions, decision makers and governments. Towns and cities have been grooving since their establishment in the past. They are facing all sorts of acute challenges in the urbanisation processes – some are due to mismanagement of resources, poor decision making, corruptions and abuses of power, inadequate of budgets and human capitals as well as lack of ideas, creativities, innovations, techniques and knowledge in planning and managing towns and cities. At the same time, advances of technologies do provide solutions needed by towns and cities. This keynote will address some challenges and expectations in liveraging the SDG. Matters like IoT, Big Data, Planning of Smart and Intelligence Cities to name a few that comes under the purview of IR4 (and IR5) will be discussed.

Title: Lean and green approach to sustainable manufacturing
Manufacturing industry has contributed majorly in the global economy especially in the developing country. The advancement of new technology has broaden cross border trading of manufacturing goods (e.g. cell phones, vehicles, and etc.). Industrialists are challenged by global competition due to cross border trading. The need to seek for operational performance improvement is very desirable. Despite the importance of operational improvement, the environmental aspect is similarly critical as well. An approach that is able to improve manufacturing performance without compromising environmental condition is very desirable. Lean and green (L&G) approach targets to improve operation and environmental performance in industry application. Lean manufacturing approach that has been pioneered by Toyota has become a good example of lean manufacturing in the manufacturing industry. Lean approach reflects positive continuous improvement outcome from the industry to achieve more effective and efficient operation. On the other hand, green manufacturing focuses on environmental performance. The synergy of both approach is able to complement each other that can further improve operation and environmental performance concurrently. Despite lean approach and green approach have been widely implemented by industrialist, there is a lack of proper implementation framework to guide the industrialist to achieve L&G. The objective of the proposed L&G framework is to provide a systematic method to assist the industry to develop continuous operation improvement and debottlenecking based on five major components (e.g. manpower, machine, material, money and environment). Generally, the five major components covers the majority of the manufacturing aspect which can reflect in operational and environmental performance. Analytic network process method will be use to reflect the weightage and prioritise the five major components to maximise lean and green factor. L&G approach will be able to improve operation performance without compromising the environmental performance. A case study is presented to demonstrate the implementation of L&G.
