ABOUT HALF OF AGRICULTURE WORLDWIDE IS NOT PRODUCING FOOD

Today, more food is grown on less land than ever before, but the number of people who are undernourished is increasing (1). Although research on this subject suggests that food insecurity has little to do with food production and is largely due to other factors, food production is predicted to become a major concern in the near future. Global agriculture must be able to address current food insecurity issues, while also feeding an estimated nine billion people by 2050 and adapting to climate change-related impacts (2). 

 

To participate in creating an agricultural system that will produce enough to feed future generations, we must understand what is grown today, as well as how, and why it is grown. From this understanding, we can make consumption choices that support a sustainable future. To start, let’s explore why crops grown for human consumption only make up 55% of agricultural production (3). If only half of farms globally are growing food, then what are the rest growing and why?

 

Today’s agriculture

 

The other 45% of agriculture is growing feed and fuel. What does this mean?

 

Feed: As household incomes increase above poverty levels worldwide, diets are shifting from primarily plant-based to incorporate more animal products (4). This shift in diet has dramatic impacts on how arable land is used because “…animal products often require far more calories to produce than they end up contributing to the food system” (5). As demand for meat and dairy grows, animal agriculture is shifting away from raising livestock on large pastures to more efficient forms of production. This means livestock is being removed from pastures that cannot be used to grow crops for human consumption anyway, and being switched from a diet of grass to grain. This requires feed for the livestock to be grown on land that could instead be used to grow crops for direct human consumption (6). Today, livestock consumes roughly one third of global cereal production (7). 

 

Fuel: As climate change mitigation becomes an increasing focus area for governments and businesses, there is growing interest in the replacement of fossil fuels with an organic substitute known as biofuels. Biofuels can be made from natural substances such as sugar cane, rapeseed, and corn (8). Biofuels are considered a climate change mitigation strategy as, contrary to fossil fuels, they are regenerative and do not release carbon dioxide that was previously stored deep underground. 

 

Biofuels are controversial however for three main reasons: 

 

• – They take up roughly 9% of agricultural production that could’ve been used to grow food (9).
• – The majority of biofuel crops are edible for humans (10).
• – Biofuels require a lot of resources to grow and they produce a lot of greenhouse gases through production and transportation that “essentially negates the perceived CO2 sequestration advantage” (11).

 

In short, our agricultural system today is far from being designed in a way that grows the most food possible and in the most sustainable way. One study estimated that “the U.S. agricultural system alone could feed 1 billion additional people by shifting crop calories to direct human consumption” (12).

 

What can you do

 

• – Change the way you eat meat: There are three ways you can do this. One, try reducing how much meat you eat. By doing so, you encourage agricultural production to grow crops that are for direct human consumption. Alternatively, replace beef with pork or chicken. This drastically reduces the amount of land and resources needed to produce your portion of meat. Lastly, look for grass-fed meat!

 

 

• – Reduce your reliance on fuel: While a hypothetical jury continues to decide whether or not biofuels are a better alternative to fossil fuels, try reducing your reliance on fuel all together! Where can you take a bike, carpool, or transit instead of driving on your own?

 

 

• – Love your food: Agricultural production will likely need to increase by 60-120% by 2050 in order to feed our growing population (13). Although you cannot control population growth on a day to day basis, you can control how much food you buy and how its stored. Did you know that 1/3 of all food is wasted (14)? If we formed better habits around food storage and use, our consumption rate as well as our grocery expenses, would go down!
