Development of an input-output based analytic hierarchy process model for disaster vulnerability assessment in Vietnam in the implementation of a bioethanol policy
In 2007, the Vietnamese Government issued the biofuel policy which requires 5% of gasoline to be replaced by bioethanol by 2025. Under this policy, sugarcane and cassava have been identified to be the main feedstocks for bioethanol production in Vietnam. These feedstocks are dependent on the agricul...

In 2007, the Vietnamese Government issued the biofuel policy which requires 5% of gasoline to be replaced by bioethanol by 2025. Under this policy, sugarcane and cassava have been identified to be the main feedstocks for bioethanol production in Vietnam. These feedstocks are dependent on the agricultural sector whose productivity relies heavily on natural conditions. Meanwhile, the onset of climate change induces natural disasters such as storms and floods and these are expected to occur more frequently in the country in the coming years. These events threaten agricultural production systems and will affect the feedstock production for bioethanol. Furthermore, the economic sectors of a country are interdependent with each other, thus disasters which directly impact the agricultural sector will affect the entire economy of any country. Knowing the interdependent relationship among various sectors can help in developing policies to minimize the over-all effect of disasters on the countrys economy. An inoperability input-output model (IIM) is developed to assess the vulnerability of the Vietnamese economy as a result of the increased interdependence between the agricultural sector and other production sectors resulting from the mandated biofuel policy.
