The estimation of spatially distributed crop water use or evapotranspiration (ET) can be achieved using the energy balance for land surface algorithm and multispectral imagery obtained from remote sensing sensors mounted on airor space-borne platforms. In the energy balance model, net radiation (Rn) is well estimated using remote sensing; however, the estimation of soil heat flux (G) has had mi...

Decision support systems able to capitalize on publicly available high resolution datasets have become increasingly valuable to agroecosystem, hydrologic and urban system stakeholders. In this paper we address the common agroecosystem modeling problem of weather-based risk forecasting. We compare storage system designs for an expandable crop disease forecasting system that relies on multiple gr...

This research was initiated to learn what the crop modeling community could do to facilitate an evolution from existing crop models toward more modular ones that can meet increasing demands. Specific objectives are to 1) use UML to design and implement a modular crop model using an object oriented language, and 2) to compare the characteristics of this model and its development with a modular m...

This paper presents a participatory modeling for multi-points of view description of a system from scientists’ knowledge. The method is applied in the development of a generic model for agro-biodiversity dynamics in developing countries with a focus on crop genetics diversities evolution through the stakeholders’ management at different scales. The model description is based on the knowledge of...
