Do international conferences overlap in their purposes?

What does the ICN Declaration duplicate (or reinforce)? As pertains hunger and malnutrition, certainly UNICEFs Declaration of the World Summit for Children (New York) and the Declaration of the Conference on Hidden Hunger (Montreal). These had an advantage in that they quantified the goals, while covering a number of the same issues. Are they all to be considered parallel or convergent efforts or duplications? Since those are only scarce human resources in the Third World available for implementing mandates emanating from these conferences, attention should be paid to preventing parallel, duplicated implementation processes.

ICN's Plan of Action covers more than the above-mentioned overlapping conferences. True. Nevertheless, I feel it reads like a catalog of largely predictable proposals inherent to a consensus document. Is it enough that it was approved in Rome by 160 countries? One wonders. The Plan of Action is not a framework for action as such giving countries guidance on options of what to do next: it includes no targeted goals, and these are needed for countries to use as frames of reference to plan and to cost their own individual plans.
