Although it's not really fair to compare two completely different centuries in a graph like this, is there any knowledge that can be derrived from the comparison being in this graph?
The truth is that the historical profitability of planting sugarcane has been sharply decreasing since 1763, despite an overall increase in sugar con-sumption worldwide over the last several decades.
The revenue from agriculture in 1763 was primarily from sugar cane and is estimated to be £12,000,000 (Ward, 1988), which is the equivalent of £2,569,010,563.25 in 2018, according to the Bank of England’s inflation calculator. This translates to roughly US$3,155,926,716 in today’s value, which is a much more sizable sum than the sugar cane industry in Jamaica produces today. Compare this to the 2019 figure of US$ 219,166,000 in food exports that Jamaica made, according to the Statistical Institute of Jamaica (2020).
