What did we learn❓
Our analysis offers nuanced insights into the mechanisms linking individual pandemic exposure to food insecurity and provides valuable implications for designing targeted policy interventions to protect vulnerable households in low- and middle-income countries.
7/n

We introduce a novel micro-level measure of “COVID-19 exposure” and employ a heteroskedasticity-based IV method to mitigate potential endogeneity concerns.
6/n

Our approach: To overcome these gaps, we examine the impact of COVID-19 exposure on food security in four African countries – #Uganda, #Tanzania, #SierraLeone, and #Mozambique – using large-scale phone survey data collected throughout 2021.
5/n

How did we advance the literature? Most studies on this topic rely on aggregate-level exposure measures, overlooking individual-level heterogeneity and introducing measurement errors that limit causal inference.
4/n

2️⃣ Our analysis identifies significant declines in household income in COVID-19 exposed areas as primary drivers of worsened food insecurity.
3️⃣ Vulnerable households often lacked financial support from governments, leading them to adopt harmful coping strategies.
3/n

We have three specific findings:
1️⃣ We find particularly pronounced impacts among households characterized by large family sizes, limited access to public services, fewer assets, and with female, younger, and less educated household heads.

It is an honour and a pleasure to serve on the Steering Committee of the FLPE. Such commitment, energy and intellectual spark in the room!

Ukraine is also fighting for our freedom. Fighting is costly. But not fighting is far costlier. Europe must fund and equip Ukraine‘s defence against tyranny, with or without the support of the USA. Peace and security are too valuable to be decided by countries not sharing our values.

We will work closely with #FAO, #IFAD, #WFP, #CGIAR and other bodies to achieve #SDG2, #zerohunger for all. I am thrilled to work with such amazing colleagues!

„Transforming food systems is necessary, possible and hugely beneficial, but also not easy“ argues Caterina Ruggeri Laderchi from the FSEC at the #GFFA25 in Berlin just now.
It is so encouraging that this can be done - however gloomy current trends are.
