More flexibility, more
outcomes? -the concept of"flexibility" of biodiversity
offset-Abstract
The paper presents "flexibility" as a new analytical view point for biodiversity offset. Analyzing marine
fish habitat offset policy in Queensland, Australia and wetland mitigation policy in the United States, theresearh organized the concept of flexibility and developed a guideline for indroduing flexibility inbiodiversity offset policy.

This paper also discuss how to interpret and justify the issue "non-identifalness" of biodiversity offset.
In recent years, demand of milk and dairy products increased with increasing incomes for Mongolians inInner Mongolia Autonomous Region, China. Milk and dairy products were food resources sacred as themain sources of nutrient from ancient times. Although the dairy has been a major industry of Inner

Mongolia, the pasturage in Inner Mongolia was excessively used by dairy and prairie was faced on thedegradation and desertification. Pasturage was forbidden by the Government in 2004. The profit of dairy
decreased with increasing the feed cost. The milk production notably increased with increasing
consumption. Consumers got nervous after the Melamine Incident (the 2008 Chinese milk scandal)
occurred aiming at cost reduction of producers. In order to seek sustainability, cost-effectiveness, supplydemand balance of milk, and dietary under the food safety, we investigated attitudes of the consumers
toward preference of milk and dairy.
The purpose of this study was to establish a framework on risk analysis for public safety oftechnological systems. Process safety was investigated to point out the lack of critical

perspectives for public safety. It was revealed that a current risk analysis mainly focuses on
detailed understanding of phenomena such as fire and explosion, and prevention ofaccidents, while it excepts societal minimization of accidental damages. The framework
consisted of a risk analysis from a viewpoint of stakeholders and a risk reduction measure
based on resilience concept. The effectiveness of the framework was validated by applying it
to a hydrogen fueling station.

approach and cost-based approach in this study. Sustainable remediation could compare environmentalfootprints and the risk of remedy works，which include the risk of traffic accidents, with carcinogenesis
risk of CVOC. In addition，relatively new technology using slant drilling was developed and also
included in this case study. The proposed technique provided the benefit of future land use by attending
the profit earnings ratio of land through the remedy duration.

technique, and the applicability to a small-scale blasting was experimentally examined. Based on theresults, the safe, speedy, and secure rescue work standard for various thickness of the wall was proposed,
which changes borehole depth and amount of explosive per hole to control a fracture manner.

Environmental Monitoring is important for risk management. In this study, simultaneous analysis
methods using GC-EI/MS and LC-ESI/MS/MS were developed for unregulated hazardous chemicals inriver water. And the analytical reliability was evaluated. Furthermore, environmental screening wereconducted in many sites to demonstrate the usefulness and reliability of method.

Persistent Organic Pollutants(POPs) in Water, Sediment, andSeafood from the Coastal Areas ofBangladesh

Bangladesh is not an exception. Three groups of POPs [polychlorinated biphenyls (PCBs),perfluoroalkyl acids (PFAAs), and polyaromatic hydrocarbons (PAHs)] were measured in water,
sediment, and seafood from the Bangladeshi coastal areas. The present levels of some POPs exceeded
the international environmental quality standards and health based guidelines, indicating potential
hazards to the ecological and human health. This study provides the baseline data on POPs pollution in
the Bangladeshi coastal area which will be useful in designing and implementing the future pollution
control strategies in Bangladesh.
