This report discusses a PAN-EARTH / Fondo Nacional de Investigaciones Agropecuarias (FONAIAP) Workshop on Crop Model Training and Calibration.

This report is a summary of the PAN-EARTH Project Annual Report from 1989-1990.

Reports on Venezuela mini-workshops held in Caracas and Mérida in May 1989 on national problems caused by global climate change.

Report on a Modeling Crop and Climate Change workshop. The objectives of the workshop were: 1) train Venezuelan scientists in the use of agricultural models IBSNAT program (International Benchmark Sites Network for Agrotechnology Transfer), including discussions about their applicability and the acquisition of knowledge about the data needed for proper simulation and validation, 2) Calibrate the model of maize (CERES) for different cultivars and different regions of Venezuela using data from soil and climate corresponding to various tests, 3) Carry out model simulations under various climate scenarios to assess their potential effects on crops, 4) To strengthen the cooperation between users of IBSNAT models to make necessary tests to get a better database application thus facilitating validation and calibration of these models, and 5) To establish plans for future agricultural and meteorological research in the context of global climate change.

Report on the PAN-EARTH Sub-Saharan Africa Workshop. This workshop focused on the effects of global climate changes on the agriculture and ecology of the countries of sub-Saharan Africa.
