@Sophal: early warning --- If your question refer to early warning, the response is that the world summits provide information that may lead to the anticipation and the prevention of negative phenomena.

This information is brought in the same debate by the governments, professional associations, academia, NGOs, international organizations etc.

Of course, action does not usually follow promptly, but no one denies the great value of collecting and analyzing information on specific issues of global concern.
