Project - Building a model for simulation of the "Dose-Response" between pesticide application and disease spread on Pepper crop cultivation to support for the development of solutions for cleaner farming practices in agriculture
The overuse of chemical fertilizers and pesticides in agricultural activities in Vietnam has caused the degradation of the soil environment, causing negative impacts on human health and other environmental factors.
This study aims to develop models capable of predicting the health and growth of pepper plants under different strategies of fungicides application, and to analyze the residues of these chemical products in the soil.
Data used to develop the models and estimate model parameters were obtained through field surveys and measurements along with the implementation of a greenhouse experiment to examine the “Dose – Response” model with more than 600 young pepper plants divided into 28 treatments. Bayesian statistical models were used to analyze these experimental data to detect the effects of fungicides on plant health and mortality.
GIS and remote sensing techniques combined with multi-criteria analysis methods and fuzzy logic were also applied to develop a decision support system for the sustainable management of the soil environment in farming activities.

Can Gio mangrove forest management and prediction Software
A supportive application that helps managers to store the forestry sampling data and report statistical charts. It has simulation features that are capable of predicting forest health and biomass under multiple scenarios and field conditions. Extensive expansion for GIS application and auto data source recognition are also available in this application.
