ASSESSING THE ECONOMIC EFFICIENCY OF CLIMATE CHANGE ADAPTATION MODELS IN THE MEKONG DELTA

Tóm tắt

The Mekong Delta is considered the largest granary of Viet Nam since most of its cultivated area is continuously supplied by annual alluvium which is significantly fertile and suitable for rice development. However, the region has been highly suffering from climate change such as sea level rise, inundation, salinity intrusion, and erosion which are seriously threatening to agriculture development, food security, and causing damage to social-economic region. As an adaptation to impacts of climate change, many new economic models have been applied in some regions of Mekong delta, and gradually brought certain efficiency in terms of economy such as mangrove cultivating seedling garden (Vuon uom), large rice-field, and rice-fish system. In order to apply and replicate these models for other regions in the Mekong delta, it is necessary to have comprehensive assessments on such aspects as ability on climate change adaptation, climate change mitigation, ensuring efficiency and sustainability in line with environment, economy and society. This paper presents approach for formulating and defining a set of criteria used for assessing climate change adaptation models in the Mekong Delta. The results show that all economic models highly adapt to climate change and bring high economic benefits. However, the applicability of some economic models is still limited.
