On average, 400,000 US dollars and a period of three years is needed to measure the effect of a development intervention, the International Initiative for Impact Evaluation concludes from its activities. These are valuable resources that need to be used carefully. Our authors describe which impact measurement methods have proved to be useful during the last few years and what their strengths and their limits are. And they demonstrate when impact evaluations make sense – and when they don’t.
Closing the data gap
In face of eleven years left to achieve Agenda 2030 and monitor the Sustainable Development Goals (SDGs) on the way there, data access, management and protection is becoming more important than ever. Moreover, identifying measures to combat climate change for resilience and food security requires the availability of accurate and up-to-date data. But data have to be collected, analysed, disseminated and maintained, and in many cases, the capacities needed for this are lacking. This section of the latest Rural 21 edition is dedicated to showcasing how to close this data gap.
