Are shocks really increasing? A selective review of the global frequency, severity, scope, and impact of five types of shocks:

Recent policy statements refer to increasingly frequent and intense shocks as one of the main reasons for focusing attention and investments on building resilience for food and nutrition security. This paper investigates whether shocks have actually increased in frequency, severity, scope, and impact by looking at historical 25†year trends for five different types of shocks: conflicts, natural disasters, climate change, food price volatility, and health crises related to food safety and agriculture.
