Adam Clarke on Joel 1:19

O Lord, to thee will I cry - Let this calamity come as it may, we have sinned, and should humble ourselves before God; and it is such a calamity as God alone can remove, therefore unto him must we cry.

The fire hath devoured the pastures - This may either refer to a drought, or to the effects of the locusts; as the ground, after they have passed over it, everywhere appears as if a sheet of flame had not only scorched, but consumed every thing.
