Mid-term Evaluation of the UNEP Medium-term Strategy 2010-2013: Working Paper on Effectiveness and Impact

This evaluation examines UNEP's effectiveness and impact across all six Medium-Term Strategy (MTS) sub-programmes. The assessment of effectiveness discusses the achievement of immediate outcomes, the level of results that can be realistically expected after an implementation period of two years, and progress towards intermediate states. The impact assessment discusses the likelihood of UNEP interventions bringing about a fundamental and durable change in the condition of people and their environment. To this intent, the evaluation has identified assumptions and impact drivers required for converting immediate outcomes into eventual impact - via intermediate states
