Uncertainty of weather can cause a lot of problems, especially to crop industry that depends on weather. Excessive or lack of rainfall can cause crop failure and hence the farmers will suffer from it. Crop failure can be considered as risk for farmers. Therefore, insurance is needed to manage the risk. There is similar characteristic between insurance and put options. Options value can be obtained from Black-Scholes method. The Black-Scholes method can be used for calculating insurance premiums. To apply the Black-Scholes method, rainfall and harvest area data are used.
