2 Pathways impact of climate change on food systems Reproduced with Biology Diagrams Climate impacts on agriculture and food supply. Agriculture is very sensitive to weather and climate. 4 It also relies heavily on land, water, and other natural resources that climate affects. 5 While climate changes (such as in temperature, precipitation, and frost timing) could lengthen the growing season or allow different crops to be grown in some regions, 6 it will also make agricultural
New University of Sydney research published in Nature Food today has modelled the wide-ranging impacts of climate change and extreme weather events on Australia's food systems and supply chains, identifying potential cascading repercussions including job and income loss as well as a loss in nutrient availability and diet quality..

Climate threat to food supply chains creates 'domino effect' Biology Diagrams
Inflation-adjusted food prices during 2023 were down from their all-time high year of 2022, (Figure 5), but are still near record levels, making the global food system more vulnerable than usual to extreme weather shocks. In addition, the number of people experiencing food insecurity is also very high (Figure 4). Shifting weather patterns, including temperature fluctuations, can cause shifts in ecosystems and reduce biodiversity. This loss affects wild food sources and pollinators like bees, which are
Unfortunately, the likelihood of having more simultaneously dry and hot years (compound extreme events) has been growing in different regions of the world (12), and this pattern is projected to continue in the decades ahead under various greenhouse gas emissions scenarios. This increasing probability will thus heighten the threat to the food supply chain.
Extreme Weather's Ripple Effect Causes Agricultural Disruption Biology Diagrams
Eighty percent of the world's crops are rainfed, so most farmers depend on the predictable weather agriculture has adapted to in order to produce their crops. However, climate change is altering rainfall patterns around the world. When temperatures rise, the warmer air holds more moisture and can make precipitation more intense.
