Global Food Consumption

Global food production vs consumption

There is enough food being produced around the world for everyone to lead a healthy and comfortable life. However, consumption rates vary due to unequal access to food. Higher consumption rates are typically found in more developed countries. But why is this the case? Let's have a look at some of the factors that could affect rates of food production, and why the developed world may have better access to food products than the developing world.

What are some factors affecting food production?

Food production rates vary around the world and can be impacted by several factors. These factors can have a knock-on effect on the amount of food that is consumed.

Climate

Climate Change is causing increasing temperatures, as well as a rise in droughts and flooding. This can make it difficult for crops to grow. In instances like this, food production reduces globally, which can increase food prices. Why? When there is less of something that lots of people want, it becomes more valuable. This pushes up the price. This impacts developing countries even more, as food becomes unaffordable.

Pests and disease

Pests and diseases can cause significant damage to crops, reducing the amount of food that can be produced. In many developing countries, farmers may not be able to afford pesticides or fertilisers that help to reduce disease damage, compared to developed countries.

Conflict

War and conflict can cause damage to land, or farmers may flee their land to safety, leaving their farming livelihoods behind, and therefore reducing food production. Conflicts can also increase food prices globally, as production is reduced.

Lack of water

Some countries may have limited access to water, due to warm climates or water pollution. The Impacts of Water Insecurity can impact agriculture significantly, as water is essential for crop growth and animal rearing.

More developed countries have better access to agricultural technologies, which means production rates are often higher. Some technologies can help to increase water supply, such as irrigation systems, which help to water the soil in more effective ways (take a look at the image below). Developing countries are often lacking in such technologies, as they are typically very expensive.

Imports and exports

Developing countries typically export higher amounts of the food they produce, meaning they send food to other countries. Because of the higher levels of exports, there is less food available for consumption in that country. This can result in food insecurities.

With smaller economies, importing food is difficult; developing countries often can't afford to bring food in from other countries. This will leave developing countries with a smaller consumption of food in comparison to their food production levels. More developed countries are often much more powerful than developing or lower-income countries, therefore they typically will be able to afford and receive more food imports. This inequality demonstrates the unequal power relations between poor and rich countries around the world.

Factors affecting the growth of global food consumption

Food consumption has been increasing globally, but what is causing this? Let's look at some of the reasons for the increased consumption of food.

Economic development

There are differences in levels of wealth all around the world, and some countries are more economically developed than others. This can be because of lower education rates, high unemployment, or poor governance, for example. Our Uneven Development explanation can help to understand why some countries may be more economically developed than others.

Over time, development levels have been changing. As countries and their populations increase their wealth, food consumption may increase. If people can afford more food, then consumption rates will rise. People will not only be able to afford more food, but also more expensive food that may be more calorie-dense, like meat, or foods from fast food companies.

Population rise

Our population has been slowly increasing over many years, reaching 7.95 billion in 2022. A rise in population will consequently cause a rise in the demand for food. This will affect things like water and land supply, as more food is being required to feed the global population.

Transport

The world is becoming more and more connected because of globalisation. Food is now transported and traded all over the world, resulting in greater access to food.

People also may now have more access to different types of foods, that weren't available before globalisation. Demands for more exotic foods can bring plentiful benefits.

With globalisation, technologies and agricultural practices can be shared to efficiently produce more food. With rising populations, producing large amounts of food efficiently is becoming ever more important, to deal with the rising demand for food and to reduce the effects of food insecurities.

Impacts of global food consumption

The rise of global food consumption, as a result of economic development, increased population and better transportation, has had many impacts. Let's discuss a few.

Food security vs food insecurity

As previously discussed, global food consumption differs around the world. There is a global imbalance of food consumption, where some countries suffer from higher amounts of food insecurity, whilst others are much more food secure. This is a surplus-deficit issue. In some countries, more commonly, the developed world, there is over-production of food, or surplus, which can result in food waste. Climate disaster, conflict, higher exports or lack of access to technologies, can mean that some countries have less access to food, resulting in insecurity and therefore have lower rates of food consumption. This is commonly seen in the developing world.

Environmental impacts

Food production has negative impacts on the environment; crop growth can damage soils, pesticides can cause local water pollution and animal rearing can increase dangerous greenhouse gas emissions into the atmosphere, contributing to global warming. Our Sustainable Food Production article discusses how food production causes environmental degradation, as well as how it contributes to climate change, in much more detail.

To reach the global food demand, foods are imported and exported around the world. This increases food miles.

The rise in food miles significantly impacts the environment, by increasing emissions of carbon dioxide into the environment, contributing to Climate Change.

Health

Health can be significantly affected by global food consumption. With rising food consumption in developed countries, there are increasing levels of obesity and malnourishment. In countries where food insecurity is an issue, reduced food consumption can have detrimental effects on health, such as undernourishment and famines.
