Future projections in global yield trends of both maize and wheat indicate a significant decline; these declines can be attributed to the negative impacts of climate change arising from increasing greenhouse gas emissions. …
How does climate change lead to food shortages?
Another change noted by the IPCC is how rising heat and rainfall associated with climate change is increasingly degrading land, making soil less productive. This is due to the loss of soil nutrients and organic matter and has negative effects on crop yields.
How does climate change affect the food system?

How does climate change affect food production in Africa?
According to the IPCC (2007), agricultural productivity will decline from 21% to 9% by 2080 due to climate change in sub-Saharan Africa. The report indicates that rising temperatures in precipitation are likely to reduce the production of stable food by up to 50%.
Why has food gone up in price?
Increases in wages in the food sector, rising agricultural commodity prices, transportation bottlenecks, and strong consumer demand have led to the highest annual grocery price increases in a decade and the highest annual restaurant price increases since the early 1980s.
