The Environmental Impact of Sustainable Foods

According to Sustainable Fisheries UW, part of the University of Washington, animal products such as beef and lamb contribute significantly to greenhouse gas emissions. The feed needed for these animals also depletes freshwater and land resources. According to Sustainable Fisheries UW of the University of Washington, deforestation is also a result of agriculture, along with biodiversity loss and habitat destruction.

Improvements to farming techniques, new technology or fish-based or plant-based foods are all alternatives that may be more friendly for the environment. Researchers are examining the potential trade-offs and the factors that would encourage people to make the switch. Environmental costs of environmentally friendly foods

According to National Ocean Service (NOS), aquaculture involves the breeding and harvesting organisms within water environments. The fuel that is used to transport or fish seafood produces a lot less carbon than conventional land animals. Plant products, such as legumes and nuts, also leave a smaller environmental impact. According to Nutritionstudy, bacteria in legume roots reduce nitrogen fertilizer requirements, and tree nuts are able to cut carbon from the air. Even the sustainable options have trade-offs. Our World in Data researchers found that the amount of water required by nuts per kilogram is more than four thousand litres, surpassing even cattle herds. In a 2018 study, Frontiers in Ecology and the Environment (19459013) published in showed that the amount of energy needed to produce livestock was lower than the amount required for aquaculture. For example, farmed catfish and shrimp were more energy intensive than pork.

Yet, on average, the carbon footprint of meat and dairy is still lower than that of these alternative products. The grocery store shopper is a major factor in changing policies to a healthier path. Shadi Athallah, an associate professor at the University of Illinois Urbana-Champaign College of Agricultural, Consumer and Environmental Sciences, said : Discover that a lot of work in sustainable agriculture focuses what government can do to help farmers adopt something, and this is good for transition. The importance of the consumer studies [play]is that we can’t rely on the government for the long term. Atallah is studying the impact of information in how people choose products. He participated in previous research conducted by the New Hampshire Agricultural Experiment Station to investigate how alternative syrups could improve the resilience of the forest in the maple industry. Atallah

investigated how informing consumers of the benefits to their environment from their other choices affected their willingness for them to choose non-maple. Researchers found that consumers are more open to alternative choices when informed about the environmental benefits of diversification.

Atallah, too, is conducting a study similar to this one on what concessions customers are willing make for their grocery items — lettuce in particular — and how much they will pay. Hydroponics and aquaponics lettuce farming costs more in terms of energy consumption, as well as cents. In the past, consumers have been willing to pay higher prices and energy costs for sustainable production because of reduced nitrogen fertilizer use. Atallah said that consumer studies such as this can give producers an idea of what consumers are willing to spend more money on. He told Explorethat the study provides both information for private companies who may want to voluntarily provide this information and policymakers considering making mandatory labeling.

Which Agriculture Is Sustainable? Researchers are researching farming methods that require less water, land and fertilizer. For example, hydroponic farming requires only nutrients-rich solutions, not soil. Aquaponics combines these basic principles with fish farming, using the waste from fish as a source of nutrients for plants. There’s another side. Jawad Khan, environmental economist and co-author at UIUC told Discover that people are looking to invest in renewable energy systems for these systems. If you install an aquaponic, hydroponic, or other system you will use renewable energy sources, such as solar grids. You could reduce the environmental impact of the energy-intensive systems if you came up with them.

According to Frontiers researchers have proposed regenerative farming as another technique for reducing ecological impacts. It is a farming technique that uses fewer synthetic agrichemicals and integrates components such as livestock, compost, groundcovers, etc. to maintain soil health.

Challenges to Sustainability

A move towards sustainable agriculture is a big undertaking that requires a lot of moving parts, including funding, incentives, and technological expertise. Khan,

told Explorethat hydroponic and aquaponic technologies are not something that a person would just start. First, you need the right skills. Atallah says the biggest barrier to wide-scale adoption is cost. He said that unless a farmer has an environmental motivation, they will not adopt sustainable practices, even if they are environmentally sustainable. Atallah, a reporter for Discovery told us that the economics behind sustainable practices are the main bottleneck. It could be as simple as developing more resistant crop varieties, or resources like semi-autonomous robotics capable of weeding without herbicides.

But the good news is that when consumers know how their food was produced, they are willing to pay for it. There is concern from consumers about reducing negative environmental impacts. Khan told Explore that it shows there’s a need for these products. Now that the manufacturers know the demand for these technologies, they will decide whether to use them or not. This information will reduce the information asymmetry.
