The way we source our food has a significant impact on both the environment and the economy. Sustainable food sourcing is a system that ensures the availability of food and its accessibility while taking into account the ecological, economic, and social impacts of the entire supply chain. It aims to reduce the negative environmental and economic effects of food production, distribution, and waste, while promoting the health and well-being of individuals and communities. According to the United Nations, food systems account for over a-third of global greenhouse gas emissions. Unsustainable food production and consumption practices, such as excessive use of chemical fertilizers, deforestation, and food waste, exacerbate climate change, soil degradation, and biodiversity loss. Sustainable food sourcing, on the other hand, can help mitigate these negative impacts by promoting regenerative agriculture, reducing food waste, and supporting local food systems. In addition to its environmental benefits, sustainable food sourcing can also generate economic benefits. Sustainable agriculture practices can enhance the productivity and quality of food, reduce production costs, and increase the resilience of farmers to external shocks, such as weather changes and market fluctuations. Furthermore, supporting local food systems can create jobs and boost the local economy. Leading academics in the field, such as Dr. Polly Ericksen from the University of Vermont and Dr. Emile Frison from the International Panel of Experts on Sustainable Food Systems, emphasize the importance of adopting a holistic and integrated approach to sustainable food sourcing. This approach should consider the social, economic, and ecological dimensions of food systems and involve all actors along the supply chain, from producers to consumers. By independently exploring these and other related academic topics, students can deepen their understanding of the complex challenges and opportunities of sustainable food sourcing, and contribute to building a more equitable and sustainable future.
In "The Soil Will Save Us," Kristin Ohlson argues that the solution to climate change may lie beneath our feet.

The invasion of purple sea urchins has devastated kelp forests along the coasts of California, Japan, Norway, Canada, and Tasmania, leaving behind barren underwater landscapes that can last for decades. However, a Norwegian company called Urchinomics has a plan to restore kelp forests and create a new fishery for overpopulated urchins through "urchin ranching." Urchin ranching could potentially create a local speciality dining market for purple urchin uni, but it will take an aggressive and thorough approach to remove enough urchins to restore kelp forests.
Did you know that manure and synthetic fertilisers emit more carbon per year than global aviation and shipping combined? A recent study from the University of Cambridge quantified the impact of fertilisers on greenhouse gas emissions, revealing that two-thirds of emissions come from the use of fertilisers, not from production. While fertilisers are crucial for global food security, their carbon emissions urgently need to be reduced. The researchers identified a combination of scalable technological and policy solutions that could reduce fertiliser emissions by as much as 80% without compromising food production. However, the implementation of such methods require various stakeholders to give up certain profits, henceforth requiring a need for a balance to be struck between environmental efforts and economic incentives.

Chemical fertilizers are widely used in modern agriculture to boost crop yields. However, these fertilizers are not without risk. In this write-up, we will explore the dangers of chemical fertilizers, including their impact on the environment and human health. We will also examine the alternatives to chemical fertilizers and the role of specific academics in this field. Chemical fertilizers can have a negative impact on the environment, particularly when they are not used in moderation. Excessive use of nitrogen fertilizers can lead to nitrate pollution in waterways, harming aquatic life and posing risks to human health. This pollution can also contribute to algal blooms, which can lead to the formation of dead zones in water bodies. In addition, the production and use of chemical fertilizers can contribute to greenhouse gas emissions, exacerbating climate change. The negative impacts of chemical fertilizers are also beyond human health. Exposure to high levels of fertilizer dust can cause respiratory problems, while exposure to nitrates in drinking water has been linked to an increased risk of certain types of cancer. Pesticides that are often used in conjunction with chemical fertilizers can also pose risks to human health. There are a number of alternatives to chemical fertilizers that can reduce their negative impact. These include organic and natural fertilizers, such as compost and manure, as well as crop rotation and cover crops. In addition, precision agriculture techniques can help farmers apply fertilizers more efficiently and effectively, reducing the risk of pollution. Leading academics in the field of sustainable agriculture have made significant contributions to our understanding of the dangers of chemical fertilizers and the alternatives that exist. For example, Dr. David Montgomery, a geologist at the University of Washington, has written extensively on the impact of industrial agriculture on soil health, and the benefits of regenerative agriculture practices. Similarly, Dr. Rattan Lal, a soil scientist at Ohio State University, has focused on the use of carbon sequestration techniques in agriculture to reduce greenhouse gas emissions. Chemical fertilizers pose a significant risk to the environment and human health, but there are alternatives that can be used to reduce these risks. By exploring the work of leading academics in the field, we can gain a deeper understanding of these issues and work to promote sustainable agriculture practices.

Polyculture farming is a sustainable agricultural practice that involves growing multiple crops in the same field at the same time. Unlike monoculture farming, which relies on a single crop, polyculture farming promotes crop diversity, which has numerous ecological benefits. One of the significant advantages of polyculture farming is its ability to enhance climate resilience. Due to climate change, extreme weather events such as floods and droughts have become more frequent, causing significant crop losses. However, by growing multiple crops, polyculture farming minimizes the risk of complete crop failure. Additionally, different crops have different root depths, which enhances soil health and reduces the risk of soil erosion. Furthermore, polyculture farming promotes biodiversity. Different crops attract different insects, birds, and other wildlife, creating a more diverse ecosystem. This, in turn, promotes natural pest control and reduces the need for harmful pesticides. Dr. Miguel Altieri, a professor at the University of California, Berkeley, has been a leading advocate for polyculture farming. He has conducted extensive research on agroecology, which emphasizes the importance of ecological principles in agriculture. Another notable researcher in this field is Dr. Ivette Perfecto, a professor at the University of Michigan. She has studied the role of biodiversity in sustainable agriculture and has found that polyculture farming can increase crop yields while promoting environmental sustainability. Polyculture farming is a promising solution to the challenges posed by climate change and the need for sustainable agriculture. Through crop diversity, it promotes ecological resilience and biodiversity, making it a vital part of our efforts to build a more sustainable future.
Soil is one of the most underrated and little-understood wonders of our planet, yet it is crucial to our survival. In just one teaspoon of soil, there are more microorganisms than there are people on Earth. These microorganisms produce antibiotic compounds that form the basis of many of the antibiotics used by humans. Soil is also home to earthworms and intricate webs of fungal threads that create space for plant roots to grow and keep soil alive. Soil provides us with almost everything we eat, and it is a valuable carbon store, capturing and locking away carbon deep underground. However, soil is under threat from intensive farming and other human activities. It takes more than 100 years to build just 5 millimetres of soil, but just moments to destroy it. It's important to value, appreciate, and protect soil for many reasons, including regulating our atmosphere, reducing flooding, and providing a biodiverse habitat. Learning more about soil can help us understand the interconnected ecosystem we're all part of and inspire us to protect this vital resource for future generations.
