Decision support system (DSS) for risk reduction in agriculture phase II: soybean DSS for Eastern Paraguay and Rio Grande do Sul (SGP-HD014)

This fact sheet describes a project to reduce agricultural production risks for soybean farmers in Eastern Paraguay and Rio Grande do Sul, Brazil, by implementing a climate-based decision support system (DSS) that utilizes seasonal forecasts and crop growth models.

• The El Niño Southern Oscillation (ENSO) is identified as the primary driver of interannual climate variability, with El Niño causing excess precipitation in subtropical southeastern South America and La Niña reducing precipitation in eastern Paraguay, southern Brazil, and central Argentina.
• The project developed a decision support system (DSS) using a probabilistic approach and crop growth models to help producers evaluate adaptive management options, such as varying planting dates or selecting different soybean varieties, based on ENSO scenarios.
• Research indicates that providing farmers with science-based information for informed decision-making is most effective when climate-based DSS are developed and implemented in close cooperation with local cooperatives.
• The project resulted in the adaptation of decision support tools for yield and climate risks for Paraguay and the planned availability of these tools for Rio Grande do Sul in Brazil.
