She added that it "is the single easiest and fastest thing that every single person can do to affect climate change." Organic material like food and yard waste makes up half of everything in California landfills and a fifth of the state's methane emissions, according to CalRecycle. These changes decrease macro- and micronutrients available in the global food supply. Good for hungry mouths and good for reducing GHGs. And if food goes to the landfill and rots, it produces methane a greenhouse gas even. F&B companies understand the crucial importance of sustainability and are doing much to achieve it, with consumer pressure and the direct impact of climate change on the industry forcing them to prioritize food sourcing; eco-friendly processes, products, and packaging; and reducing food waste. "Changing individual behavior [to avoid food waste] could be one key towards mitigating the climate crisis." Food security, climate change, and malnutrition can no longer be addressed independently of one another54. Food Tank: The Food Think Tank celebrates World Environment Day with a spotlight on how reducing global food waste can address hunger, poverty and climate change. Here, we calculate the energy content of nationwide food waste from the difference between the US food. Food that is produced but not eaten ends up in landfills and creates methane, a powerful greenhouse gas. But climate change is only one of many pressures on agriculture. The contribution of food production, food consumption and food waste to climate change is presented in Section 5. Few people realize when they shove some grapes into the bottom drawer of their refrigerator and forget about them, they are contributing to climate change. Climate change and associated severe weather, droughts, fires, pests, and diseases are already threatening the production of food around the world. "If we want to get serious about tackling climate change, nature and biodiversity loss, and pollution and waste, businesses, governments and citizens around the world have to do their part to reduce food waste", said Inger Andersen, Executive Director of the UN Environment Programme (UNEP). While it may not be getting much attention at COP21, food loss and waste plays a huge role in the global climate change battle. As a general trend, developing countries suffer more food losses during agricultural production, while food waste at the retail and consumer level tends to be higher in middle- and high-income regions - where it accounts for 31-39 percent of total wastage - than in low-income regions (4-16 percent). Climate change impacts vary among diverse social groups depending on age, ethnicity, gender, wealth, and class. Reducing wasted food would probably help lower dangerous emissions into the atmosphere and slow down climate change, according to experts. Pollution. Fossil-fuel energy is very important for food and agriculture systems. When we lose and waste food, we still use all the energy, water, land, supplies and human energy it takes to grow, store, harvest, transport, package and sell it. "Avoiding food loss and waste would therefore avoid unnecessary greenhouse-gas emissions and help mitigate climate change," co-author Prajal Pradhan said in a statement . Haddad writes that a discussion of global food security should also address the different needs of higher and lower income groups, maximize resilience of the food chain in the face of climate change and social conflicts, and minimize greenhouse gas emissions. Well what about wasted food? 3. But it turns out that agriculture and land use, as well as the larger global food system, are among the biggest contributors to climate change. Understanding and ending food waste has therefore been a priority among nonprofit organizations and governments which leads us to discussion on the causes, effects, and solutions to food waste. The Intergovernmental Panel on Climate Change (IPCC) report on food security found there to be a multiple number of reasons and factors that affect food waste. This month, the United Nations' Intergovernmental Panel on Climate Change (IPCC), released a summary of their comprehensive report Climate Change and Land. Heads of governments and agriculture ministers from around the world have recently met to discuss ways in which food waste can be reduced. Despite data and modelling uncertainties, the magnitude of the figures above suggest that a reduction of food losses and waste at global, regional and national levels would have a substantial positive effect on societal resources and in particular, climate change. Whether to mitigate climate change, to address food insecurity and hunger, or simply to save money and natural resources, more countries are investing in food waste reduction efforts and partnering with food. Collectively, such measures could raise production by as much as 20 percent, depending on how the climate changes.8. the emissions of other gasesincluding methane and nitrous oxide. People who produce food -- like farmers and fishers -- are often hit hardest by climate change, which directly affects their personal food supply and sources of income. In addition, they are more resilient and resourceful and are better able to deal with the impacts of climate change. An adequate food supply isn't just crucial for sustained nutrition -- it's also essential to the economic well-being of food producers. Agriculture both contributes to climate change and is affected by climate change. This problem is getting worse, with nearly a 50 percent increase in food waste since 1974. Once lockdown ended, however, food waste rose again. Climate change is generally seen as having a negative impact on food security, particularly in developing countries.3,7,8. Consider for a moment that, by weight, around a third of all food produced for human consumption is lost or wasted. Climate change will not only affect food production and consumers; as optimal growing conditions shift with the climate, communities that depend on fishing or farming for their livelihoods will be disrupted. In light of this growing food waste problem, let's look at the impact of food waste on the environment and what we can do to reduce it. When people throw food out, all the resources to grow, ship, package and produce it are wasted too, including massive amounts of water. By simply rethinking how you shop and cook, in most high income countries at least, it should be possible to reduce the amount we waste and so lessen our contribution to climate change. Food waste fell sharply last year during lockdown as people stuck at home began to use leftovers, plan meals and freeze food rather than throw it away. Climate Change. Here's what you need to know about eating meat, dairy, seafood and produce, and preventing food waste. global, regional and national levels would have a substantial positive effect on societal resources and in particular , climate change. And that's not including any number of other food-related solutions on the list. In general, beef and lamb have the biggest climate footprint per gram of protein, while plant-based foods tend to have the smallest impact. If climate change occurs unchecked, the agriculture sector will feel the effects in a disproportionate measure and we are already seeing this happen. "Agriculture is a major driver of climate change, accounting for more than 20 percent of overall global greenhouse gas emissions in 2010," said co-author Prajal Pradhan. Climate change exacerbates health inequities by disproportionately impacting people living in poverty and communities of color. Food that gets spilled or spoilt before harvesting - or when being stored, packed or transported - is known as food loss. Climate change is reducing productivity in agriculture 1.4. food security) has been widely researched and debated. Growing, processing, packaging and transporting food all contribute to climate change. According to the UN, global food waste adds 3.3 gigatons of CO2-equivalents to global greenhouse gas emissions annually. When food is wasted, all the resources used to produce it are also wasted. Food loss can be caused by weather or insects, or by high temperatures and poor storage. It threatens our air, food, water, shelter, and security the basics on which human life depends. If food waste was measured as a country it would be the third highest emitter of greenhouse gases. People across the world are becoming increasingly concerned about climate change: 8-in-10 people see climate change as a major threat to their country.15. A global model finds that the environmental impacts of the food system could increase by 60-90% by 2050, and that dietary changes, improvements in technologies and management, and reductions in food loss and waste will all be needed to mitigate these impacts. Food waste problem worse than previously thought. Air pollution from a factory in Nepal. Current uses of natural resources are highly stressed 1.3. It identified low income countries as contributing 40% of food waste, and high income countries to be contributing 53% of food waste. Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and CO2 emissions from decomposing food, impacts global climate change. When we think of climate change and greenhouse gas emissions, we usually envision power plants, factories, cars, and smokestacks not farms and ranches. A study by Project Drawdown, a coalition of experts focused on climate change solutions, ranks reducing food waste as the No. About 28 percent of waste happens in such businesses as restaurants and grocery stores. As I have shown before, food production is responsible for one-quarter of the world's greenhouse gas emissions. To be sustainable, food production must occur within food-related planetary boundaries for climate change, biodiversity loss, land and water use, as well as for nitrogen and phosphorus cycles. means the land, energy and water used in the production of the food are wasted and the associated carbon emissions were needlessly created. Food that is fit for human consumption, but isn't eaten, is called food waste. Cutting food waste is a delicious way of saving money, helping to feed the world and protect the planet. He said in a statement that the research clearly demonstrates that food has a much greater effect on climate change than is widely known. Image: Food and Agriculture Organization of the United Nations. Your diet affects climate change. Read more: Should there be a 'meat tax' to fight climate change? Worldwide, women play a key role in food security, although regional differences exist. An elevated increase in demographics will boost demand for food 1.2. Among them, shifting people to majority plant-based diets, reducing food waste, and planting crops that are genetically superior in the face of climate uncertainty. By banding together with fellow diners and shoppers, we can push for policies that limit waste and redirect uneaten food to where it's needed. [14] For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity. In every aspect of food production, petroleum is used. However, production must also be sustainably intensified to meet the global population's growing food demands. Limiting the impact of climate change to 1.5 degrees Celsius would mean major changes for agriculturefrom how we farm, to how we eat and waste food, to how we manage our forests and.
