Evaluating the Effectiveness of Climate Change Adaptation and Sustainable Development of the Rice-Black Tiger Shrimp Model in the Coastal Area of Cainuoc, Mekong Delta

Abstract

“Evaluating the effectiveness of climate change adaptation and sustainable development of the Rice-Black tiger shrimp model in the coastal area of Mekong Delta” was conducted in Cainuoc commune, Ca Mau province, an area strongly affected by climate change, specifically the increasingly severe and complex annual saltwater intrusion. The research period was from June to August 2025. The research content focused on surveying the productivity of the rice-black tiger shrimp farming system from three different aspects, In the first phase socio-economic and cultural data of people in the research area was collected. In the second phase it was carried out a survey of the productivity of the rice-black tiger shrimp farming system. In the third phase a comparison of the effectiveness of rice-black tiger shrimp farming systems, rice monoculture and shrimp monoculture in terms of input and output costs was analysed. Research results showed that monoculture of rice or shrimp farming did not bring efficiency into either of the farming systems. The rice farming system even requires compensation in order to receive the same efficiency as can be obtained in the rice-shrimp farming system. The rice-black tiger shrimp farming system is much more effective than the other farming systems. This result is also the foundation for further research to serve the farming model adapted to current climate change conditions and sustainable development. At the same time, this is also an important source of data and information for related sectors in formulating appropriate local agricultural and rural management policies for the rice-shrimp farming system.
