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.
Did you know that seaweed could be the answer to global food insecurity and reducing greenhouse gas emissions? Seaweed is not only a dietary staple and carbon soaker, but also holds potential for replacing plastics, animal feed, and biofuels. Researchers from the University of Queensland have mapped out the potential of farming more commercially important seaweed species and estimated that expanding seaweed farming could reduce global agricultural greenhouse gas emissions by up to 2.6 billion tonnes of CO2-equivalent per year. However, careful management is needed to avoid potential ecological impacts.
As a student, you might have heard about the importance of reducing your carbon footprint to help combat climate change. One way to do this is by cutting down on the amount of meat you eat. Did you know that approximately 15% of all greenhouse gas emissions from humans come from livestock production? By reducing our meat consumption, we could significantly reduce these emissions. Not only that, meat and dairy production take up a lot of land, around 80% of all farmland! However, not all meat is created equal. Large-scale farming of beef has a particularly high impact, whereas small-scale farming of animals can have a lower environmental footprint. Vegan alternatives can also come with their own set of problems, but a plant-based diet can bring several positive health benefits. By changing how we look at food and eat it sustainably, we could potentially change the world.
Seaweed may be the future of sustainable and nutritious food. As the global population continues to grow and traditional agriculture methods take a toll on the environment, seaweed could be a more efficient and eco-friendly option. Researchers are exploring the potential of seaweed not only as a food source, but also as a tool to combat climate change. Companies like Dutch Weed Burger, AKUA, and Umaro Foods are already developing plant-based alternatives to meat and dairy using seaweed, which is high in nutrients and can be grown without land or fresh water.
In "The Soil Will Save Us," Kristin Ohlson argues that the solution to climate change may lie beneath our feet. Thousands of years of poor farming practices and modern agriculture have stripped the world's soils of up to 80% of their carbon, contributing to atmospheric warming. But by adopting ecological approaches that prioritize the health of soil and its microorganisms, we can turn atmospheric carbon into beneficial soil carbon and potentially reverse global warming. Ohlson introduces readers to the visionaries who are figuring out how to build healthy soil and solve problems like drought, erosion, pollution, and food quality. Recommended for environmentalists, farmers, scientists, and anyone interested in sustainable agriculture and combating climate change. Kristin Ohlson's "The Soil Will Save Us" challenges conventional thinking about farming practices and offers a hopeful solution to the climate crisis. The book has particular relevance to those studying ecology, environmental science, and agriculture, as well as those working in fields related to food and sustainability. It highlights the importance of healthy soil and its role in mitigating the effects of climate change, making it a must-read for anyone interested in creating a more sustainable future.

Meanwhile, Green Bio Energy in Uganda is producing briquettes from waste that not only provide a healthier option for cooking but also create employment opportunities. Sylvia Herzog of the Charcoal Project sees briquettes as a stepping stone to cleaner forms of energy. Could eco-friendly briquettes be the solution to reducing air pollution and improving human health?
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.

Scientists are investigating how feeding seaweed to cows could help reduce their methane emissions, which contribute to the climate crisis. Methane is a potent greenhouse gas, and cows like Nugget, a milk-producing Jersey cow at the University of New Hampshire's Organic Dairy Research Farm, contribute significantly to its production. Researchers are testing various species of seaweed, which have been shown to reduce cow burps, and measuring their impact on methane output. The goal is to find a seaweed species that is optimal for both methane reduction, cow and human health, while also being environmentally sustainable to grow at scale.
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.

Have you ever heard of growing plants without soil? It's possible with hydroponics and aquaponics! These innovative methods of agriculture have gained popularity in recent years for their ability to produce high yields of fresh produce while using less space, water, and pesticides than traditional farming. In this write-up, we'll explore the fascinating world of hydroponics and aquaponics, diving into the concepts, benefits, and contributions from leading academics in the field. Hydroponics is the practice of growing plants in nutrient-rich water instead of soil. This method can be done in a variety of ways, from a simple jar with water and plant roots to complex systems using pumps, pipes, and controlled environments. Aquaponics takes it a step further by combining hydroponics with fish farming. In this closed-loop system, fish waste provides nutrients for plants, while plants naturally filter and clean the water for the fish. Did you know that hydroponics and aquaponics can yield up to 10 times more produce than traditional farming methods? This is because the plants receive precisely the nutrients they need, and water is recycled efficiently. Additionally, these methods can be done year-round, in any climate, and with less land space. It's no wonder that hydroponics and aquaponics are gaining attention from both commercial farmers and hobbyists alike. One leading academic in this field is Dr. Dickson Despommier, a professor at Columbia University. He's written extensively on vertical farming, an innovative form of agriculture that takes hydroponics to new heights by stacking layers of plants vertically. Another notable academic is Dr. Rakocy from the University of the Virgin Islands, who pioneered the development of modern aquaponics in the 1980s. In conclusion, hydroponics and aquaponics offer an innovative and sustainable solution to traditional farming methods. With its ability to produce more fresh produce with less resources, it's no wonder why this field is gaining traction. By exploring this topic further, you can discover new and exciting ways to apply academic concepts to real-world problems.
Looking for a way to stabilize dipping crop yields as climates become harsher and unpredictable? Look no further than the ancient and simple technique of planting maslins - a combination of cereals that can include rice, millet, wheat, rye, barley and more - and harvesting them together as one product. Used by farmers across at least 27 countries for over 3,000 years, maslins have been found to yield higher stability under changing conditions and convey many of the ecological benefits of polycultures involving entirely different plant types. Researchers believe that maslins could provide huge benefits across all levels of farming, from subsistence to industrial, particularly in areas already facing challenging climate conditions. Two researchers, Morgan Ruelle and Alex McAlvay, conducted a review of previous work at Cornell University, demonstrating the effectiveness of maslins in experimental trials.
