![]() ![]() ![]() I supplemented the data with manual research for 2022 for the largest 25 economies to make sure no major changes (such as the US becoming energy independent) were missed. Therefore, we use 2019 data to see general trade patterns.Įnergy data comes in a more comfortable format but is relatively old. The latest data is from 2021, when pandemic supply chain issues disrupted global trade. Ideally, we would have this data broken down into calories but since that’s not available, weight appears to be linked closer to calories than value. Now we need to decide whether to measure trade based on value or weight. This isn’t ideal since this might well include non-food items like cotton but it’s close enough. To estimate global food trade, we pick trade in agricultural products. ![]() The result will be close enough to the truth to see meaningful global patterns. We will therefore need to work with readily available data. This isn’t a PhD thesis and I only have a day, rather than four years, to work on this. What exactly to measure is tricky to work out. Being self-sufficient is great, as you don’t rely on trade to keep the people fed and the lights on. A nation that exports more energy or food than it imports is a net exporter. Such datasets aren’t readily available, so compromises are required. Understanding whether a nation is a net exporter or net importer of either food or energy is a bit tricky.
