miss these two chapters are typical conventions, we can neither change them nor we can alter them, one of my relative concerning to field of environmental sciences guided to me, that environmental governance, the policies that has given in this chapter are not to remember, that are just once go through to have an idea as the preparation of environmental is quite tricky, these policies are just for references not for cramming.
Regarding to global initiatives, these are typical conventions things to be remembered are " where it held, date, purpose, objectives, response of first and third world, international diplomacy on latter stages, final outcome..
i have searched number of sources to find them in easy way and lastly, i concluded that skills and tactics are more important to handle these topics than wasting time in searching for easy wordings...

So you are suggesting to get these prepared objectively. But these are two full length sections, how come such preparation would be sufficient? Kindly share your views about question patterns.

miss you interpret me wrongly....these are neither for long question nor for objective...let me give you the example..suppose the questions arises in papers is regarding to air pollution, your are writing," Air pollution is the main cause of respiratory diseases, according to air pollution environmental policy of Pakistan section (f), air pollution should be controlled for healthy biodiversity..
Now this is what i mentioned "reference", that you don't need to cram them these are just use to cite in professional quoting or writing..
a similar example is like a general articles of laws that i guess u have read somewhere, e.g " according to article 52 (B) of constitutional law, the privileges of president should be limited..Means no one is going to cram or mention the overall statement of article 52(b), but just for reference, similarly these are the laws and articles of environmental sciences used for giving reference...hope you understand now..but if still you feel uncomfortable and not satisfied than simple go for cramming all these in similar manner without any alteration or change numbering or sequence..

Now, for global initiatives, this is the long portion chapter and you have to handle it tactfully...let me suggest you a outline and you have to remember the details in points forms under consideration of this outline, somehow it is not strict rule you can make addition or removal as per you cognizance or convenience..
For example question is about KYOTO PROTOCOL.. try to remember all these things while preparation.
1)Introduction to KYOTO PROTOCOL
2)History
3)UNED climate change report; threat to biodiversity (what kind of threat?).
4)Objective and principle concept of PROTOCOL
5)First commitment period;
1) with reference to participation of First World.
2) with reference to role of third world world.
6)Flexibility to accomplish the Target
1)IET
2)CDM
3)JI
7) Ratification;
which country still ratify and which leaved and why?
8) final outcome
if you remember 10 to 12 lines of your register paper under each heading it would be sufficient to fill 5 leafs which i guess enough for answer.

i think that the paper wil comprise on the questions on the issues not conventions......so better to focus on the first five sections

Anyone having a masters in Environmental Science is requested to share with us, a sample paper of Environmental Science. It will help us in having an idea regarding our relevant topics. Thank you.

Nation builder.....seems like you have good grip on ES. Please tell a person with no science background can handle this subject or not?

Is there any book available in pdf? plus there is too much difficulty in finding guidelines if one has to cover this subject by self study.
Thank You
