Research

I am interested in integrating statistical methods with environmental assessment tools for risk analysis of agricultural systems.
Tools for environmental assessment of systems, such as Life Cycle Assessment, provide multiple indicators useful for guiding agricultural systems towards environmental sustainability. However, agricultural production systems depend both on farmer management practices and on natural environmental conditions, which are not controllable. Uncertainty and variability due to farmers’ decisions and climate and economic conditions must therefore be considered when assessing environmental impacts of agricultural systems. In this context, risk analysis methods will help in the decision-making process to improve environmental performances of agricultural systems.
