Biosecurity has multiple meanings and is defined differently according to various disciplines. The original definition of biosecurity started out as a set of preventive measures designed to reduce the risk of transmission of infectious diseases in crops and livestock, quarantined pests, invasive alien species, and living modified organisms (Koblentz, 2010). The term was first used by the agricultural and environmental communities. Starting from the late 1990s in response to the threat of biological terrorism, biosecurity encompasses the prevention of the intentional removal (theft) of biological materials from research laboratories. These preventative measures are a combination of systems and practices put into its place at bioscience laboratories to prevent the use of dangerous pathogens and toxins for malicious use, as well as by customs agents and agricultural and natural resource managers to prevent the spread of these biological agents.〔http://www.sciencemag.org/cgi/content/full/295/5552/44a Meyerson and Reaser 2002, Science 295: 44〕 Advances in technology have meant that many civilian research projects in medicine have the potential to be used in military applications (dual-use research) and biosecurity protocols are used to prevent dangerous biological materials from falling into the hands of malevolent parties. The National Academies of Science define biosecurity as "security against the inadvertent, inappropriate, or intentional malicious or malevolent use of potentially dangerous biological agents or biotechnology, including the development, production, stockpiling, or use of biological weapons as well as outbreaks of newly emergent and epidemic disease". Biosecurity requires the cooperation of scientists, technicians, policy makers, security engineers, and law enforcement officials. ==Biosecurity as international security (human security) issue== Initially, health security or biosecurity issues have not been considered as an international security issue especially in the traditional view of international relations. However, some changes in trend have contributed to inclusion of biosecurity (health security) in discussions of security (Koblentz, 2010). As time progressed, there was a movement towards securitization. Non-traditional security issues such as climate change, organized crime, terrorism, and landmines came to be included in the definition of international security (Koblentz, 2010). There was a general realization that the actors in the international system not only involved nation-states but also included international organizations, institutions, and individuals (Koblentz, 2010). Therefore, ensuring the security of various actors within each nation became an important agenda. Biosecurity is one of the issues to be securitized under this trend. In fact, in January 10, 2000, the UN Security Council convened to discuss HIV/AIDS as a security issue in Africa and designated it a threat in the following month. The UNDP Millennium Development Goals also recognize health issues as international security issue (Koblentz, 2010). Several instances of epidemics that followed such as SARS increased awareness of health security (biosecurity). Recently several factors have rendered biosecurity issues more severe. There is a continuing advancement of biotechnology which increases the possibility for malevolent use, evolution of infectious diseases, and globalizing force which is making the world more interdependent and more susceptible to spread of epidemics (Koblentz, 2010). Some uncertainties about the policy implementation for biosecurity remain for future. In order to carefully plan out preventative policies, policy makers need to be able to somewhat predict the probability and assess the risks; however, as the uncertain nature of the biosecurity issue goes it is largely difficult to predict and also involves a complex process as it requires a multidisciplinary approach(Koblentz, 2010). The policy choices they make to address an immediate threat could pose another threat in the future, facing an unintended trade-off. Policy makers are also constantly looking for a more effective way to coordinate international actors- governmental organizations and NGOs- and actors from different nations so that they could tackle the problem of resource overlap (Koblentz, 2010). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「biosecurity」の詳細全文を読む スポンサード リンク
