Young people are the future and their nutritional needs are critical for the well-being of any country. As highlighted in the recent Global Accelerated Action for Health of Adolescents (AA-HA!) report investing in the nutrition and health of adolescents brings a triple dividend of benefits for the adolescent now, for their future adult lives, and for the next generation.

The three new Laureates deserve the prize in economics in memory of Alfred Nobel. But the award shows how poor the modern economics discipline is in terms of gender equality, research methods, self-examination, and genuine insight into the lives of the poor.

Certification systems, like Fairtrade, Rainforest Alliance and organic agriculture are crucial social capital in the food system. They need to show that they are credible. Therefore, a large part of published research on sustainability in food production concerns the impact of certification. The focus of this research is often to measure the effect on household income. Giel Ton argues that impact research might need to shift its focus to explore new policy options within the certification process, looking at crucial elements of the certification process that need to be improved to remain relevant and credible, especially ways to improve the cash premium and way to reach living wages for workers.

Metrics are useful, and the widespread use of standardised metrics and ratings[1] have been helpful over the years. Still, many of the claims of the social impact from investments tend to focus on good news stories or a narrow set of metrics, such as jobs created. With the increased interest in mobilising private capital to address poverty and sustainable development, perhaps it’s time to be more evaluative about social impact?

A new paper on African investments offers insights into improving social benefits: it can be achieved but requires intentionality by business leaders and fund managers. This isn’t without a cost – something that only serves to highlight structural weaknesses in many fund operating models. The overheads available to support social performance are often tight. So, do donors and philanthropists have a role to play while this fledgling investment ecosystem emerges?

Some years ago, Tony Saich likened doing research on local government in China to the story of the blind men and the elephant – the complexity of China, and the differences between places, mean that different people experience different things, and describe different realities.

The latest IDS Bulletin ‘The Millennium Villages: Lessons on Evaluating Integrated Rural Development‘ brings together a series of reflections on integrated development and how best to know whether it works and why. It certainly doesn’t provide all the answers; rather it’s meant to stimulate debate. Some things you might agree with, others you might not. Hopefully, it is at least thought-provoking.

At Itad, we see choosing an evaluation approach as an art as much as a science: there’s always a lot to consider. As a result, our evaluation designs are often hybrids, drawing on a range of different approaches in order to tick all the boxes.

We like a challenge at Itad, and so four or five years ago we threw our hats into the realist evaluation ring. At that time, there was growing interest in the international development sector about the potential of realist approaches to answer tricky questions about how and why our programmes work or don’t work.

In my last blog, I provided an update on how investors and companies monitor the performance of smallholders in supply chains. In this one, I ask – what are the barriers and incentives for collecting more relevant data on smallholders who work with agribusinesses?
