Development of a New System Approach to Land Use Sustainability with Various Interfaces

Abstract

(System Approach to Land Use Sustainability) model is developed from CERES and DSSAT is designed to simulate the impact of agronomic management on yield and environmental impact. SALUS model has new approaches and algorithms for simulating soil carbon, nitrogen, phosphorous, tillage, soil water balance and yield components. In the past, the use of the crop model was not easy for general users like farmers and officers because of the detailed input data and complex setup. In order to increase the usage of crop model, we develop a web-based applications, SALUS Simple Interface and SALUS-WEBGIS system, besides the existing SALUS desktop version. SALUS Simple Interface is a user friendly application interface without cumbersome steps. People could know what the sensible management practice for their fields is by using the SALUS Simple Interface. SALUSWEBGIS helps people to know the spatial variability of crop yield and soil condition. Users could improve their management strategies according to the simulation. SALUS Simple Interface and SALUS-WEBGIS could assess the impacts on the environments under different management practices through the spatial and temporal variability. The simple operations could engage more people to understand the importance of sustainable development and try to improve on agronomic management.
