Effect of climate change on food chain
Climate and food

This is particularly clear in the case of barley, maize, millet, pulses, rice and wheat. It seems that the countries most at risk of food shortages are also worst affected by rising temperature. This seems to bear out the finding from the world’s premier climate science advisers, the Intergovernmental Panel on Climate Change (IPCC), that the higher average global temperatures and more extreme weather events associated with climate change will reduce the reliability of food production. The latest IPCC report also supports these conclusions.
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. In addition, accelerating rises in sea levels will compound these negative impacts by increasing saltwater intrusions and permanently flooding crop land.

Climate change and food: The potential impact on production and prices

Climate change could affect food production across the globe.
Sub-Saharan Africa, including South Africa, is at high risk of climate impacts on food availability and affordability.
Higher average global temperatures and more extreme weather events associated with climate change will reduce the reliability of food production.
Here the authors explore the potential impact of a changing climate on food production and prices.
In a world with an increasing human population, climate change may have a serious impact on our ability to grow enough food.
Research from as far back as 2007 found that around 30% of year-to-year fluctuations in tonnes of crops grown per hectare were due to changes in the climate. It is remarkable under these circumstances that the global agricultural system has managed to remain fairly robust, and that major food shortages have been rare.
On the other hand, food prices in recent decades have become increasingly volatile. While there are many influences on food prices – including crop yield, weather variations, international trade, speculation in food commodity markets, and land management practices – mostly open trading systems have allowed food shortages in some places to be offset by surpluses, and increased production, elsewhere.
Several studies forecast the same alarming trend for global food security: crop yield will continue to decline as the planet warms. Hence experts believe that as climate change worsens, not only will we see more of these export bans, but also a rearrangement of trading patterns between countries as they prioritize national interest. Climate change increases the risks to food production and distribution, so countries will move toward more regional and “mini-lateral” trade agreements to offset any potential damage from disruptions, says Alex Capri, a researcher at the Hinrich Foundation, a Singapore-based philanthropic organization that supports sustainable global trade. “Climate change is absolutely driving nationalistic behavior.Climate risks impacting the agricultural sector are direct risks to the food supply chain. All components of the food chain from food production, food processing, retailing/ distribution to consumption are impacted by accelerated climate variability. For instance, increased frequency and intensity of droughts, floods, heat waves and other extreme events directly threaten food productivity and soil health, leading to severe food shortages. Subsequently, this will result in a rise in food costs, affecting livelihoods of producers, spending capacities of consumers and success of food-related businesses alike. It is also important to note that these food shortages are likely to affect poorer parts of the world disproportionately. This makes the food system particularly vulnerable to change, especially in an agrarian country like India.Climate risks impacting the agricultural sector.
