Abstract
Although Vietnam has become the third biggest rice exporter in the world, famine is yet challenging managers in many provinces, especially in the Northern mountainous areas of Vietnam. In contrast with financial profits, formal rice supply chains have recently not provided enough food for all people in these provinces. The ecosystem service approach has the potential to give better chances to communicate with decision makers, especially with agricultural managers by raising awareness and improving understanding related to potential, flow and demand of/for rice provision. In this study, probability approaches through a Bayesian Belief Network (BBN) and statistical approaches through a Hybrid Neural-Fuzzy Inference System (S-HyFIS) were used to quantify and map the potentials of the rice provisioning ecosystem service (RPES) in the Sapa district in the Lao Cai province in northern Vietnam. In addition, various statistical data related to actual rice production, population numbers and rice consumption were collected from 1990 to 2010 to quantify the RPES flows and demands. A conceptual model depicting the relations between RPES potential, flow and demand is proposed, in which the efficiency of site selection for rice cultivation and implemented farming practices play important roles in determining RPES supply. The results indicate an ineffective use of farming practices in the 1990s and show improvements in the new millennium in the case study area. A small surplus of RPES supply was found in the whole Sapa district since the year 2003, which has been used for tourism and export purposes. At the same time, the RPES demand was unmet in six communities. To generate a better rice supply chain and to better match supplies with actual demand, parts of the surplus of RPES could be transported from service providing areas to neighboring poor communities.
