So, pandoc does not parse the content of latex environments, but you can fool it by redefining the commands in your header.tex file: \usepackage{lscape} \newcommand{\blandscape}{\begin{landscape}} \newcommand{\elandscape}{\end{landscape}} Thus, here \begin{landscape} is redefined to \blandscape, and \end{landscape} to \elandscape.
