Environmental Assessment and Management(partially),
can be covered from any good environmental science book/s.

For remaining portions of syllabus, like:
Environmental Governance, Global initiatives, Environmental Assessment and Management(partially), and Interdisciplinary nature of Environmental Science, at least right now Internet seems to be the best option.

Also, FPSC has also listed websites of Pakistan Environmental agency and UN environment program as suggested readings, compounding the importance of Web resources even more in my mind.

Moreover, since this is the first time the exam of this optional will be held, so no past papers or authentic guidance is still available. Extensive cooperation with other aspirants and thorough preparation of syllabus is the key I think for success.
