In your game, you only have one source of income which is Chilean Woodlands. I don't see where the Atacama is but I assure you don't have any other source of income.
So you have total of 4 income.
-1 because of the blue 1 bonus near Chilean Woodlands.
3 Total income then.
You have a light blue territory in the North West. So that's -3. Now you have 0 income.
Look more carefully and all the answers are available :)
gonkia simply had to blockade 2 of his territories to gain income and ultimately win the game, so really the result was the correct one given the board.
