Complexity of the Socio-Ecological Dynamics in Hong Ha Commune in the Vietnamese Highland-A Review through the Coupled Human and Natural Systems Framework

In Vietnam, government policies have led to improvements in the national forest cover and poverty situation. However, numerous recent case studies in the Vietnamese highland found that socio-ecological dynamics were highly complex on a local scale, resulting in unintended policy impacts and varying policy success among regions. While such complexity has become apparent, it has been difficult to understand and compare between regions, as assessment methods and targeted aspects of socio-ecological dynamics differed between case studies. In this review, complex socio-ecological dynamics in Hong Ha Commune in Thua Thien Hue Province were identified in published case studies and organized into complexity features based on the coupled human and natural systems (CHANS) framework, to make information more accessible and comparable under the widely applied framework. All complexity features of CHANS systems were identified in the reviewed literature, such as feedback loops (between illegal forest use and flood damage), heterogeneity (in incomes between Kinh people and ethnic minorities), and telecoupling (of the local livelihood through tourism). Based on its applicability to Hong Ha Commune, the CHANS framework is suggested to be applied in other forested areas of the Vietnamese highland to understand and compare complex socio-ecological dynamics and evaluate policy impacts.
