Conteúdo: 	Increments in yield and reductions in costs and risks of failure became basic requirements for competitiveness in the current globalized agribusiness world. Increased efficiency in the use of resources and inputs, improved quality of farm products and environmental conservation are some challenges of modern agriculture. Tools to help the decision making process are essential to tackle these challenges and succeed in obtaining competitive and environmentally sustainable products. Water availability is one of the main factors responsible for soybean yield variability in time and space. In a collaborative project involving several institutions (MAPA, EMBRAPA, ANEEL, INMET, IAPAR), areas with lower risks for soybean cropping were delimited in the states of PR, GO, TO, MS, MT, MG, MA and BA. Using soybean crop water balance simulation models, geographical information systems and geostatistics, areas with different probabilities of water deficit occurrence during the most critical phase of the crop development were defined and characterized as favorable, intermediate and unfavorable, based on: different sowing dates, water availability in each region, water consumption in the different stages of development of the soybean crop, soil type and cultivar. For each State, 54 to 72 maps were generated as a result of the combination of 9 or 12 sowing dates, 3 soil types and 2 cultivars. Each map portrays a combination of a level of each one of the factors listed above, representing the drought risk classification of different areas of the State for a given sowing date, as a function of the soil type and cultivar.
