Divided into two chapters, this dissertation presents a linear programming model to optimize agricultural activity for selected regions in Western Bahia considering the hydroclimatic forecasting model and the indicators and possible economic gains from the adoption of the rainy season onset forecast in the region. In the first chapter, the application of the linear programming model at different levels of water use demonstrated that the model could provide information to optimize agricultural activity in the region, especially in scenarios of delay or reduction in rainfall, in addition to being able to guide governance actions by water resources. The second chapter presents the economic indicators of agricultural activity for the Western Bahia, showing that the equivalence of an irrigated hectare occurs on average in 3.90 hectares of rainfed land and that the adoption of the forecast model for the beginning of the rainy season can generate increases up to 30% in revenue generation from agricultural activity.
