The main aim of this study was to examine residents’ environmental behavior in sorting solid household waste, and to identify the integrative factors that contribute to their wasteseparation cooperation and other related pro-environmental behaviors. This was achieved based on a questionnaire survey in Shenyang, Chengdu, and Shanghai. Methodologically, we applied a discrete choice model to examine whether individuals’ garbage sorting behaviors differ based on their characteristics, social attributes, residential circumstances, and environmental awareness, and whether these factors are correlated with individuals’ receptiveness to a refuse charge system, or to policies requiring garbage sorting. We further examined whether individuals’ garbage sorting behavior, their receptiveness to fee-based waste collection, and their receptiveness to policies requiring garbage sorting differ across areas. In this particular survey, we introduced a 16 item scale of pro-environmental behavior and a nine item scale of altruism to ascertain the ways in which internal motivational factors affect people’s environmentally conscious voluntary behavior. Overall, the present work is expected to contribute to an important understanding of the motivational forces and incentives behind human pro-environmental behavior and action. It also brings relevance to the analysis of moral solidarity in relation to the household waste disposal problems currently confronting us today.

Flooding is a water event inundation the land area due to the overflow of water from rivers or rainwater runoffs with high intensity. Kanagawa Prefecture is a country of Japan that has overcome flood events with a simple and high-tech flood control system. The conservation of watersheds and green open spaces as water catchments and the use of naturally occurring and artificial rivers and ponds show the simplicity of the flood control technology adopted by the Kanagawa Prefecture government. Subsurface drainage is a high-tech flood control system that is connected to surface drainage and guttering system in resident's housing. Based on the Kanagawa experiences, this study is an effort to apply the concept for the Makassar City of Indonesia, which the flood still occurs. Data collection methods were conducted with direct observation in the field and were described qualitatively based on the facts and literature approaches. The results of the analysis indicate that the type of flood control such as Miyagase dam in Kanagawa prefecture is the same as the Bili-Bili dam on Jeneberang River as flood control in Makassar City. The high-tech flood control type in Kanagawa Prefecture is sub-surface drainage that has not been applied in Makassar. This research is expected to be a reference for the Government of Indonesia, especially the City of Makassar in formulating policy concerning solving the problem of flooding.

Although it is important that disaster waste be demolished and removed as soon as possible after a natural disaster, it is also important that its treatment is environmentally friendly and economic. Local municipalities do not conduct environmental and economic feasibility studies of pre-disaster waste management; nevertheless, pre-disaster waste management is extremely important to promote treatment of waste after natural disasters. One of the reasons that they cannot conduct such evaluations is that the methods and inventory data required for the environmental and economic evaluation does not exist. In this study, we created the inventory data needed for evaluation and constructed evaluation methods using life cycle assessment (LCA) and life cycle cost (LCC) methodologies for future natural disasters. We selected the Japanese town of Minami-Ise for the related case study. Firstly, we estimated that the potential disaster waste generation derived from dwellings would be approximately 554,000 t. Based on this result, the land area required for all the temporary storage sites for storing the disaster waste was approximately 55 ha. Although the public domain and private land area in this case study is sufficient, several sites would be necessary to transport waste to other sites with enough space because local space is scarce. Next, we created inventory data of each process such as waste transportation, operation of the temporary storage sites, and waste treatment. We evaluated the environmental burden and cost for scenarios in which the disaster waste derived from specified kinds of home appliances (refrigerators, washing machines, air-conditioners and TV sets) was transported, stored and recycled. In the scenario, CO2, SOx, NOX and PM emissions and total cost were 142 t, 7 kg, 257 kg, 38 kg and 1772 thousand USD, respectively. We also focused on SOx emission as a regional pollution source because transportation and operation of the temporary storage sites generates air pollution. If the treatment of all waste were finished in 3 years, the environmental standard would be satisfied by setting work duration to 4.8 h/d.
