Project

AgMIP Impact Explorer as a visualization platform

The aim of this project is to further develop the e-infrastructure for crop system modelling and crop yield forecast by contributing to relevant global initiatives such as the Agricultural Model Intercomparison Project (AgMIP) and the Global Yield Gap Atlas (GYGA).

In these projects through model intercomparison, model application, data base development, data schematization and rich client interface development, relevant steps in IT will be made to realize an advanced e-infrastructure for crop growth modelling and forecasting supported by a global community.

Results

A generic data model STAC has been developed to store agronomy related data in a very generic, powerful yet simple way. Loading and storage of public weather data has been implemented and is used to generate crop model (WOFOST) input weather files. A start has been made to store and open in-situ data collected in within the GEO-GLAM initiative.

The Global Yield Gap Atlas portal and web map viewer was designed and constructed (www.yieldgap.org) giving access to underpinning data, methodology and protocols and yield gap data for cereals at different spatial levels.

ESG participated in the inter-comparison of crop models around grain maize. A large number of base, scenario and sensitivity runs were conducted for 4 different sites (USA, Tanzania, France, Brazil) to explore the behaviour of WOFOST under different scenarios of temperature and rainfall.
