Describe the effects of pollution on the ganges river. what role does population play on this pollution?

After many late nights of hard work, more planning meetings than you care to remember, and many pots of coffee, your initiative has finally gotten off the ground. These are general criteria that should be used as a basis for developing evaluative questions through the full range of evaluations topics, i.e. from single intervention through to thematic, and ways of conducting the evaluation, e.g. joint evaluation.

Taken together, these five criteria should provide the decision-maker with the essential information and clues to understand the situation and determine what should be done next.

To the extent that specific evaluations have specific purposes, that there is no one right way to conduct an evaluation and that these criteria are interdependent and not mutually exclusive, their relative meaningfulness for a specific evaluation should be assessed and trade-offs discussed in each case to ensure that key questions are addressed and to avoid unnecessary effort and expense.

In addition, use of the five criteria does not exclude that other criteria might be used as well to better focus the evaluation on specific characteristics of the intervention and its context.

I hope I can help you :)
