Decision support system for risk reduction in agriculture Phase II: Soybean DSS for Eastern Paraguay and Rio Grande do Sul, Brazil IAI Small Grant Program for the Human Dimensions Panama, February 2008
Outline • Who we are • Goals & Objectives • Cooperators • Approach • Summary
Who are we? Julian Baez Universidad Nacional de Asuncion Clyde Fraisse University of Florida Mauricio Fernandes EMBRAPA-CNPT Norman Breuer University of Miami Victor Cabrera New Mexico State Willingthon Pavan Universidade de Passo Fundo
Goals & Objectives • Our main goal is to help producers mitigate climate risks affecting agriculture in Eastern Paraguay and Rio Grande do Sul • To conduct stakeholder assessments to better understand needs and expectations; • To evaluate the impact of ENSO phases on soybean yields using crop simulation models; • To strengthen the capacity of professionals in Paraguay, Brazil, and the USA in agricultural systems modeling, use of participatory research methods for climate research, and interdisciplinary collaboration. • Integrate with CRN II: Land use change in the Rio de La Plata Basin: Linking biophysical and human factors to predict trends, assets impacts, and support viable land-use strategies for the future
Where will we focus our research? Eastern Paraguay 5.85 mmt of soybeans during the 06/07 cropping season Rio Grande do Sul 9.92 mmt of soybeans during the 06/07 cropping season Soybean cover in South America Source: www.mongabay.com
Our Strategy: Work with Cooperatives in Brazil and Paraguay Cooperativa de Agricultores de Plantio Direto 12,000 members Rio Grande do Sul, Brazil
41 filiaisCooplantio 142 assessores técnicos
Cooperatives – Paraguay 8 cooperatives in Itapua and Alto Parana ~ 300K ha

Research PlanCrop Modeling Component • DSSAT CROPGRO-Soybean Model • Data collection effort • Historical weather data • Soils • Management • ENSO climate scenarios • Alternative planting dates and maturity groups • Results will be disseminated to producers via a web-based DSS

Training • Modeling workshop will be offered at the University of Passo Fundo in October 2008
In Summary • Well qualified multidisciplinary team • Very well connected with stakeholders • Technical background and experience in participatory research and crop modeling • Experienced in developing web-based DSS • Ready to work but still waiting for solving contract language issues between the IAI and University of Florida
Thank you! cfraisse@ufl.edu
Roadblocks • Funds not available yet • Legal language between IAI and UF not compatible • Dozens of emails between sponsored programs, IAI, PI • The end appears in sight • Data collection in Paraguay will demand extra effort
Previous Research – IAI Seed Project (a) (b) • Precipitation Probability of Exceedance • Planting to flowering • Flowering to first seed • First seed to maturity (c) Fraisse et al., 2007 – El Niño – Southern Oscillation Influences on Soybean Yields in Eastern Paraguay.
