This report reflects the efforts of the Office of the Orinoco-Apure Project to define an environmental policy based research delineating priority areas of research and identification of potential environmental impacts of the project.

Report for the Project Orinoco - Apure. This report discusses information on the Orinoco river delta and other deltaic tropical systems.

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

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 dynamics and control of aquatic weeds in some islands of the protected area of the Orinoco Delta.

This report is section three of a study of the Llanos del Rio Orinoco. The aim of the study is to establish relationships between the characteristics of plant communities of the Central Plains of Venezuela and geomorfogenetica and pedogenic evolution during the Quaternary.
