Agrometeorological Monitoring System Agritempo The Agrometeorological Monitoring System (Agritempo) monitors and divulges, since 2003, the climatic risk mapping out aiming at reducing possible crop losses. www.agritempo.gov.br
Characteristics stores and manages daily data of 1280 weather stations; stores historical data from 4870 meteorological stations; manages more than 50,000,000 records; stores and uses data from estimates of 1 to 15 days; allows the registration of users with different profiles; incorporates migration process and validation of data received from institutions; provides resources for generation of graphics, research and statistical summary; agricultural zoning; daily generation (automatic), 27 agroclimatological bulletins daily generation (automatic) of 810 thematic maps for all of Brazil

Brazilian Agricultural Zoning Agribusiness GDP in 2006: US$ 180 billions (33% GDP - US$ 500 billion) Agribusiness Exportations: US$ 35 billions (42%) Grain production in 2007 :133,4 millions tons Program coordinated by the Department of Agriculture and EMBRAPA (National Institute for Agricultural Research) since 1995 Federal Farm Credit Policy US$ 8 billion (US$ 2.5 billion for small farmers
Cause: Water deficiency in critical phases: : 60% Agritempo Loss of production: 91/92 e 92/93 (Source: IPEA/UNB) Product S. PAULO BAHIA Northeast Rice 30% 34% 47% Bean 21% 34% 41% Corn 16% 37% 71% Soybean 16% 29% - Soybean- Irrigated - - 32% Cotton 22% 22% 81% Castor Oil - - 87%
Agritempo Main Objective Decrease the climate risks dry spells during flowering and grain-filling (60%) excessive rain during the harvest period (30%) Product Planting Calendars Crops: Corn, Soybean, Beans, Rice (Wheat, Sorghum, Fruits, Coffee and biofuel crops) Periods: Dekad (10 days), Oct to Dec (Jan to Dec) Counties / Municipal districts Macro-regions: Central, Southeast,South and Northeast Risk: less than or equal to 20%
General Methodology Simulation of cumulative water balance for different soil types, planting dates, cycle lengths, ground stations (different models (DSSAT, BIPZON Sarrazon, CLIPS etc) Decision criteria / Risk Analysis: a) WRSI during reproductive stage Threshold Value (80% of all simulated years) WRSI: Water Requirement Satisfaction Index WRSI = actual / maximum evapotranspiration b) Excessive rain during harvest
Data Base Length of four growth stages (Initial, Vegetative, Reproductive and Maturity) for early and normal cultivars Length of total growing period Crop coefficient (Kc) Soil water holding capacity Rainfall Evapotranspiration
