I agree with these points. I was thinking why the food security situation in parts of Africa sometimes appears to be worse than parts of Africa. Wondering if this is due to a combination of el Nino/la Nina situations tending to affect Africa relatively more than Asia/L.America (Catharine, your thoughts ?), and that there is relatively more serious conflict related situations certainly in parts of West Africa and Eastern Africa (eg currently S.Sudan and Somalia). Wondering whether the SE Asian monsoons seem to be relatively less affected by severe el Nino/la Nina fluctuations ?
