How does climate change affect food security? – Challenge accepted

Usually, when I tell people what I study, I get asked: how does climate change affect food security? Some may expect this: “climate change is increasing food insecurity.” But that’s an irresponsible statement. Food security is the product of many factors, it can’t be summarised into one sentence.
Still, what if the average person wants to find out the impact of climate change on food security? They do have to deal with both climate and food on a day-to-day basis, the curious non-specialist demands an answer and I’m on a mission. How does food security affect climate change? To provide an answer in layman’s terms: challenge accepted.
There’s also an element of predicting future events. Just to be clear: no one and nothing can predict the future with 100% confidence. The future is the future and it remains uncertain. What we do have, however, is the past. Whatever you may have heard about climate change and its future impacts comes from past information used as a guide to project the future.
How does climate change affect food security? is a four-part series that explains how extreme weather events associated to climate change or climate change consequences (i.e. precipitation variability or increased average global temperature), affect each stage in food systems: production, procession, distribution or consumption.
Where is the food security part? Since food security is an outcome of food systems, this series is actually a close look at each of the steps that contribute to food security. In each post we’ll learn with the help of an example or case divided into 4 parts: a) extreme weather event; b) direct and indirect consequences; c) impact on food security; and d) lessons learned.
Is there any specific climate change/food security relationship you would like me to research and write about? Feel free to comment in the section below.
