In English, use the plural with anything greater than one, even if it's less than two.
This changes to these if the noun that follows is in the plural.
Also avoid the use of this instead of the personal pronoun: John had the book but he gave this to his brother should be John had the book but he gave it to his brother.
The demonstrative word (this/that etc.) must agree with its noun. In the example, kind is singular and so this must agree with it.
