I suggest the slightly more efficient variation:

  (defun jk-org-kwds ()
    (org-element-map (org-element-parse-buffer 'element) 'keyword
      (lambda (keyword) (cons (org-element-property :key keyword)
                         (org-element-property :value keyword)))))

The optional argument `element' prevents `org-element-parse-buffer' from
diving too deep and `org-element-map' does the job of `mapcar'.
