Growing up in a Korean household, soy took on a variety of forms in our kitchen and dining room: soy sauce, tofu, soybean sprouts, soybean paste, red pepper paste, soy milk… the list is endless. 

Hence, moving to the United States presented a succession of cultural shocks, such as the lack of soy food products, beyond its prominence in food and cosmetics as soy lecithin. 

Nevertheless, in recent years, soy has taken its throne as an internationally recognized source of protein and pivotal contributor to achieving global food security. According to the World Economic Forum (WEF), in addition to its nutritious value, soy contributes up to two-thirds of the world’s livestock feed; the efficiency of this plant-based protein has the potential to achieve food security on an international level. 

Unfortunately, unsustainable soy production also causes negative environmental and societal impacts. In this article, I will be tackling soy’s controversial standing among environmentalists and why it’s not the bad guy.

Firstly, what is food security and why does it matter?

According to the World Food Summit of 1996, food security is defined as

“all people, at all times, [having] physical, social, and economic access to sufficient, safe and nutritious food to meet dietary needs for a productive and healthy life.”

This means that even if everyone has access to food, it does not fulfill the full definition of food security. 

I, for one, don’t feel energized enough to attend all my lectures and have a proactive day when I only eat one meal consisting of burgers and french fries. People need food, but they need nutritious food that can sustain a healthy lifestyle.

With this definition in mind, the fact that nearly 8.9 percent of the world population suffer from hunger establishes the numerous layers to the issue of food insecurity, starting with the general lack of access to food and ending with limited access to safe and nutritious food.

According to the World Food Program, 135 million people suffer from acute hunger largely due to “man-made conflicts, climate change and economic downturns.” The UN Sustainable Development Goal No. 2 aims to end world hunger, achieve food security and improved nutrition, and promote sustainable agriculture by 2030.

How can soy solve food insecurity?

You may wonder how soy can solve such a multi-faceted dilemma of food security. First, let’s take a look at some of the courses of action that can be taken to relieve hunger. The World Vision lists the following options as methods of tackling world hunger:

  • Providing immediate hunger relief
  • Offering education and resources for sustainable agriculture
  • Addressing the root causes of food insecurity: availability, access, utilization, and stability

With regards to the agricultural aspect of solving the issue, the United Nations Department of Economic and Social Affairs (UNDESA), offers more specific solutions within the production aspect:

  • Implement efficient irrigation strategies
  • Reuse drainage water and water resources of marginal quality
  • Reduce usage of fertilizer
  • Improve crop protection to reduce food waste and post-harvest losses
  • Create more sustainable livestock and marine production

These solutions ultimately strive to increase crop yield while reducing water consumption through innovative technologies and sustainable agricultural practices. 

Impact-driven startups such as Kajou and Tigoun work within the food security sphere to decrease food waste by diversifying natural cashew products in local areas and forming ecological conservation bags to store produce, respectively.

However, soybeans themselves fall under the category of immediate hunger relief. As stated in the World Bank Group’s 2020 Global Market Report on Soybeans, soybeans are among the few complete protein vegetable-based foods with nine essential amino acids.

The versatile nature of soybeans allows for its pervasive presence in our lives through food products, soybean meal, oil, and even biodiesel production!

What are the drawbacks of soy production?

Soybeans truly seem like a holy grail amidst the food insecurity crisis, yet why are they so controversial?

The World Wildlife Fund (WWF) shares the various consequences of soy production on its natural and social environment. In the past decade, soybean production has centralized in tropical South American countries such as Brazil, Argentina, Bolivia and Paraguay. 

The rapid expansion of the soybean cultivation industry has led to deforestation and poses a great threat against the vulnerable species inhabiting the Amazon rainforest. 

Corresponding with the destruction of forests and natural habitats, soy farming causes soil erosion.

The highly mechanized process of its cultivation also results in soil compaction

If this doesn’t already sound problematic, deforestation in these countries have dislocated hundreds of indigenous communities and small farmers, and contributed to the exploitation of workers

Unfortunately, it doesn’t end there. Deforestation and area conversion also threatens the atmosphere with carbon dioxide emissions. The WWF states that CO₂ emissions associated with land conversion of the Cerrado in Brazil is equivalent to more than half the total emissions from the United Kingdom for 2009. 

Air pollution goes hand in hand with water contamination: agrochemicals and fertilizers pollute the natural water sources such as rivers, lakes, and estuaries. Ultimately, such factors raise concerns about soybean production as doing more harm than good for the world.

How can we address these issues?

Soybeans are not only a staple in my diet, but tie closely with my culture and heritage. Nevertheless, knowing the harmful effects of its cultivation brought feelings of guilt and self-consciousness in my active participation in the soy market.

Thankfully, most of these issues can be realistically addressed and curbed. 

New agricultural methods such as conservation tillage minimize erosion, and using lands that are not classified as ‘highly erodible’ is a simple addition to an effective practice. 

Moreover, identifying areas of high conservation value in terms of cultural and environmental aspects is a necessary step in encouraging transparent land-use planning and resolving negative impacts. 

The WEF encourages soy cultivation on pastures already cleared for cattle farming. According to the article, more than 25 million hectares of such land currently exists in the Cerrado. Organizations like the Roundtable on Responsible Soy (RTRS) also promote the sustainable soy production and trade through the development, implementation, and verification of a global certification standard.  

What we can conclude from this information is that…

Soy is not the issue. The problem lies in the unethical and unsustainable man-made practices in soybean cultivation and trade. Hopefully, this means that in the future, I can still eat tofu every day without feeling guilty.
