| The Canegro sugarcane model simulates the daily energy, water and biomass balances of a sugarcane crop using atmospheric, soil, cultivar, and management inputs. South Africa and Swaziland maintain, improve and apply independent versions of the model. An older version of the Canegro model is distributed as part of the decision support system for agrotechnology transfer (DSSAT version 3.5) to registered users worldwide. The purpose of the DSSAT multi-crop modeling system is to act as a framework to promote scientific co-operation and to globalize the application of crop models. The Canegro model has been used successfully to support agronomy research, forecast cane yield and support agronomic management of sugarcane production. The model has been calibrated and tested against observations in South Africa, Swaziland, Mauritius, Australia and Thailand with varying degrees of success. Although significant modeling advances have been made recently, these have not been incorporated within the DSSAT shell and are not available to DSSAT users. Although model source code is freely available, programming and modeling expertise are required to refine models for local conditions and to incorporate improvements into the DSSAT shell. Furthermore the DSSAT system is currently being redesigned to enable easy interchange between modules and to standardize on common, soil and atmospheric modules. The Canegro model needs major revision to make it compatible with this new system. This revision should also address the need for model documentation and a crop management module capable of simulating long-term sugarcane rotations. It is proposed that a consortium of potential DSSAT Canegro users be established to address these issues. The aim would be to ensure the continued maintenance and inclusion of sugarcane modeling advances into the DSSAT system. It is envisaged that consortium members contribute financially and in kind towards approved projects. The main cost would be salaries for consultants or postgraduate students. Benefits would include (1) access to advances in our understanding of the crops' response to the environment and management, and (2) a more robust model tested under a wider range of growing conditions and genotypes. The paper will present examples of the successful application of Canegro. Recent advances and the main limitations of the model will be discussed. Problems with the DSSAT v3.5 will also be highlighted. Different options will be discussed for the establishment and role of a DSSAT Canegro consortium to address these challenges. | |
