“…Moreover, even where RCTs would be feasible in theory, they require considerable investments of time and money, which makes RCTs impractical in many settings. Fortunately, advances in statistical approaches now make it possible to still derive rigorous estimates of policy impacts in many of these cases, although this requires careful analysis (Angrist and Pischke, 2010 [55]) (Athey and Imbens, 2017 [56]) (Cunningham, 2021[57]).…”

Food systems are expected to provide food security and nutrition, to contribute to the livelihoods of millions, and to do so in an environmentally sustainable way. The broad outlines of these challenges are clear, and in many cases evidence exists on how better policies can improve the performance of food systems. But there are considerable gaps in data and evidence. This paper provides a panoramic overview of different types of evidence gaps on food systems and their causes, and makes the case that better evidence is needed to enable better policies. At the same time, evidence will never be complete. Policy makers and the research community thus need to adopt a pragmatic approach, focusing on where better evidence can make the biggest difference.

“…Single nutrient estimates—for example, for iron or vitamin A—suggest that 3–3.5 billion people, but perhaps more, lack one or more essential nutrient. That is four to five times the number of undernourished people (Gómez et al 2013), reflecting the fact that the most affordable nutrient‐adequate diet exceeds the cost of adequate dietary energy by a factor of 2.7 (Bai et al 2020) and that few people make dietary choices to minimize the cost of a fully healthy diet. At the same time, the number of overweight or obese people now exceeds 2 billion globally.…”

“…The core problem is that healthy diets are unaffordable to an estimated 3 billion people globally, with affordability lowest in SSA, mainly due to the relatively high cost of fruits and vegetables (Bai et al 2020; FAO et al 2020; Hirvonen et al 2020). But income growth among the poor is only a partial solution to the problem of access to affordable healthy diets.…”

The world faces formidable, but manageable, challenges in achieving food security in a world growing beyond 9 billion people in the coming decades. Five big challenges will necessitate shifting innovation strategy to place greater emphasis on sustainable increases in diet quality, on total factor productivity ‐ not just crop yield ‐ growth, on social protection programs, on Africa, on post‐farmgate agri‐food value chains, on risk management, and on reducing the land and water footprint of food production. We must be progressive in both senses of the term, having faith in science as an engine of societal advance, and standing with marginalized populations.

“…Comparing the two panels reveals how fruit and vegetable prices spiked in April before northern hemisphere summer but declined thereafter in seasonal patterns documented elsewhere 21 , while dairy and eggs, meats, and pulses, nuts and seeds rose later making them more closely linked with case counts over time. Given the importance of these food groups for low-cost nutritious diets 22 , their high prices during COVID-19 is a major threat to nutrition security around the world.…”

The COVID pandemic has cut lives, livelihoods and supply chains, leading to price spikes for some foods and decline for others. We compare monthly retail food prices in up to 180 countries through February 2021, and find significant rises for more nutritious food groups with higher case counts. Prices by food group complement data on farm commodity prices and overall consumer price indexes, and can help guide policy for resilience and response to shocks.
