For example, while the output of a capacity building exercise on the impact of climate change on agricultural productivity can be identified relatively easily (e.g. x number of people trained), identifying the outcome of this activity (e.g. drought-resistant crops planted on y hectares of land) is more difficult to identify. The impacts of such an activity (e.g. improved food security) will be even more difficult to attribute, given time lags, natural variability in weather patterns, “shifting” baselines due to the effects of climate change, and interactions with outcomes/impacts from other related interventions. While assessing the effectiveness of an intervention in producing project-level outputs is relatively straightforward, attributing long-term, global impacts to an intervention is extremely challenging.
