Where’s the Waste? A ‘Circular’ Food Economy Could Combat Climate Change (Published 2019) (1)

By Eduardo Garcia

CHICAGO —A gigantic steel cylinder shines in the afternoon sun outside The Plant, a 93,500-square-foot “living food laboratory” here. To the untrained eye, it looks like a space rocket. But it’s not.

It’s an anaerobic digester.

Bubbly Dynamics, the organization that nine years ago converted this former meatpacking facility into a hub for local food businesses, said that, once completed, this “mechanical stomach” would turn organic waste into compost, biogas and a nutrient-rich liquid in which to grow algae.

The digester is expected to help Bubbly Dynamics implement a circular economy, a model that could help fight climate change by feeding a rapidly growing urban population with food grown locally using organic methods, according to experts. This closed-loop system would create little to no waste because materials would be reused, shared, repaired and refurbished.

According to the Intergovernmental Panel on Climate Change, the global linear production system that relies on chemicals and fuel to produce and transport food over great distances is to blame for between 21 percent and 37 percent of the world’s greenhouse gas emissions. However, proponents of the circular model argue that cooperation among various groups in the food-production system can significantly reduce energy consumption and waste.

The Plant, which is home to about 20 food businesses — including a kombucha brewery, a coffee roaster, a chocolate maker and a vegan-ice-cream maker — is among the global pioneers of the concept.

The indoor farms are irrigated with rainwater, and some of the energy is generated from solar panels. The spent grain from the Whiner Beer Company, the building’s largest tenant, is mixed with wood chips and horse manure to produce roughly 20,000 pounds of compost a month, and some of the carbon dioxide from the fermenting process is used to stimulate the growth of plants and algae.

The wastewater from Just Ice, an artisanal ice company in the basement, is channeled to a wetland in the lobby that has a vertical garden, or living wall, fishes and turtles.

“At its heart, The Plant is primarily a tool to fight climate change,” said John Edel, founder and director of Bubbly Dynamics. By reusing organic waste instead of letting it rot in a landfill, this facility keeps methane, a powerful greenhouse gas, away from the atmosphere.

“It has many other benefits to pass around, like providing economies of scale to small businesses so that they can compete with larger ones,” he said. “If the money stays local that helps everybody.”

Some of the collaborations that have allowed The Plant’s low environmental footprint have been encouraged by Plant Chicago, a nonprofit that promotes circular economy practices.

“It’s about collective action, that’s the next frontier. We need to get the Chicago food community to work collectively toward shared goals,” said Jonathan Pereira, executive director of Plant Chicago.

But The Plant, a gigantic food laboratory, is also about science and technological innovation. Researchers at the mycology lab are trying to grow mushrooms in the spent grain from the microbrewery, and Backyard Fresh Farms is developing robots controlled by artificial intelligence to tend to its plants.

Back of the Yards Algae Sciences wants to use algae to produce protein-rich food as an alternative to meat.

In many ways, meat production and climate change are entwined. Worldwide, livestock accounts for from 14.5 percent to 18 percent of human-induced greenhouse gas emissions and, each year, the amount of forested land that is cleared — in part to create pasture land for cattle — releases emissions equivalent to driving 600 million cars.

But Back of the Yards Algae Sciences, The Plant’s newest tenant, said that algae could be the bedrock of a sustainable, largely plant-based food industry.

“I mean, what really excites me in this building is that it was operating for almost a hundred years,” Leonard Lerer, founder of Back of the Yards Algae Sciences, said. “The meat of hundreds of millions of pigs was probably processed in here. And soon we will be able to make a burger that is 100 percent algae-based and cruelty-free.”

And urban farming is growing in places like New York, Paris, Shanghai, Singapore and Tel Aviv, for good reason.

A 2018 study suggested that urban farming could ameliorate some environmental problems in cities by increasing vegetation cover, removing atmospheric carbon dioxide and offering a habitat for bees and other pollinators. It could also help increase food security and reduce food waste, said Matei Georgescu, one of the study’s authors and an associate professor of geographical sciences and urban planning at Arizona State University.

“Because society largely depends on food grown elsewhere, the ‘out of sight out of mind’ mentality has led to nonsensical quantities of food waste,” he said. “Reconnecting people to the food they eat is likely to lead to decreased waste.”

Take Lufa Farms in Montreal, for instance. Since it opened a commercial rooftop farm in 2011, it has been doubling the amount of food it produces every two years. It now grows about 50 varieties of veggies in three hydroponic rooftop farms that generate “virtually no waste.”

That’s in part because it only harvests by order and sells products only in Montreal. In addition, Lufa saves energy by warming its farms with the excess heat emanating from the buildings below, captures rainwater for irrigation, packages products in compostable plastic and relies on 25 electric cars to deliver some of the 17,000 baskets it sells every week via its online farmers market.

Where Lufa got “very nerdy,” said co-founder Lauren Rathmell, was with so-called biocontrols, which use living organisms to fight pests.

“We were really naïve to think that there wouldn’t be that many insects in this area of the city. I don’t know what we were thinking, but we’ve had everything you could probably have in a farm or a garden, and learned to deal with it, incredibly effectively, using not a single synthetic pesticide,” said Ms. Rathmell, a trained biochemist.

Lufa turned its greenhouses into high-tech living ecosystems that host dozens of insect species including “good bugs” like parasitic wasps, ladybugs and predatory mites to keep pests under control.


As a result, Ms. Rathmell said, Lufa demonstrated a commercially viable way to supply urbanites with greens grown sustainably in rooftop greenhouses — a system that is particularly suitable for cold-weather cities with short growing seasons.

Lufa estimates that by converting 19 rooftops of average-sized shopping centers it would be able to supply all of Montreal — which has a population of about 1.8 million — with sustainably grown veggies. While Lufa has considered spreading to the Northeast United States, it, like other companies in the circular economy sphere, says it believes that “slow growth” is the best way to be faithful to its principles.

“What we’re trying to build is something that can last. Something that can have an impact on access to quality, fresh produce in cities, where more and more people are. Montreal is the test bed but we see this as a multigenerational endeavor,” Ms. Rathmell said.

Produce grown using regenerative farming practices can often be out of reach to low-income consumers. But some argue that circular economy practices can be used to actually democratize access to healthy food.

That’s the tenet of Saladorama, which works with six farms to produce and distribute healthy meals to low-income communities in three Brazilian cities.

Saladorama reduced costs by reaching consumers directly, without the “six to eight” intermediaries that often make healthy food prohibitively expensive, said Hamilton Henrique, Saladorama’s founder. The company also saves on transportation because it grows food within urban areas and delivers its meals by bike.

“The main challenge was this social construct that healthy food is only for the elites,” Mr. Henrique said through an interpreter.

Can the circular economy model that is being pioneered by these organizations help fight climate change?

According to the Ellen MacArthur Foundation, a British charity that promotes the circular economy, a large-scale circular food economy would help reduce greenhouse gas emissions by 4.3 billion metric tons of carbon dioxide a year, the equivalent of taking one billion cars off the road.

Its argument is that it makes sense to grow more food near urban areas because 80 percent of the world’s food will be consumed by cities in 2050, according to the Food and Agriculture Organization of the United Nations. About 40 percent of the world’s cropland already exists on or near cities.

The foundation is working with six major food companies, including Nestlé and Danone, and with three cities — London, New York and São Paulo, Brazil — to lay the foundations of a “holistically healthy food system,” said Emma Chow, who leads the foundation’s Cities and Circular Economy for Food initiative.

“Our goal is that every meal and every piece of food, that the very act of eating, help solve rather than contribute to climate change and biodiversity loss,” she said.


How the circular economy tackles climate change? ›

How a circular economy cuts greenhouse gas emissions. By adopting the principles of the circular economy – eliminate waste and pollution, circulate products and materials, and regenerate nature – we can tackle those emissions associated with industry, agriculture, and land use – the remaining 45%.

Is circular economy the solution to climate change? ›

About 45 percent of global greenhouse gas emissions can be addressed through the circular economy, says Ellen McArthur Foundation. Meanwhile, shifting from a take-make-waste economic model to a more circular one promises to unlock trillions of dollars in economic value.

What percentage of climate change is caused by food waste? ›

Globally, wasted food accounts for about 8 percent of all greenhouse gas emissions. The environmental consequences of producing food that no one eats are massive.

What is a circular food economy? ›

A circular economy for food mimics natural systems of regeneration so that waste does not exist, but is instead feedstock for another cycle. In a circular economy, organic resources such as those from food by-products, are free from contaminants and can safely be returned to the soil in the form of organic fertiliser.

How does reducing food waste help climate change? ›

And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide. About 6%-8% of all human-caused greenhouse gas emissions could be reduced if we stop wasting food.

How does food waste increase climate change? ›

But what does food waste have to do with climate change? Basically, rotting food produces methane, a potent greenhouse gas. By sending this food waste to landfill, Australians are generating methane equivalent to around 6.8 million tonnes of carbon dioxide.

What is an example of circular economy? ›

In a circular economy, manufacturers design products to be reusable. For example, electrical devices are designed in such a way that they are easier to repair. Products and raw materials are also reused as much as possible. For example, by recycling plastic into pellets for making new plastic products.

What is circular farming? ›

Circular agriculture aims to minimize inputs of concentrate feed and chemical fertilizer as well as outputs of harmful substances and waste. Residual products from one chain are feedstocks for another.

Where is food wasted? ›

Where Is Food Lost? Edible food is discarded at every point along the food chain: on farms and fishing boats, during processing and distribution, in retail stores, in restaurants and at home.

What are 5 ways to reduce food waste? ›

Here are some easy actions you can take to re-connect to food and what it stands for:
  • Adopt a healthier, more sustainable diet. ...
  • Buy only what you need. ...
  • Pick ugly fruit and vegetables. ...
  • Store food wisely. ...
  • Understand food labelling. ...
  • Start small. ...
  • Love your leftovers. ...

How does waste impact climate change? ›

Our Wasteful Impact on Climate Change

Solid waste contributes directly to greenhouse gas emissions through the generation of methane from the anaerobic decay of waste in landfills, and the emission of nitrous oxide from our solid waste combustion facilities.

How is food waste affecting the environment? ›

Impacts include: greenhouse gas emissions of more than 42 coal-fired power plants; enough water and energy to supply more than 50 million homes; the amount of fertilizer used in the U.S. to grow all plant-based foods for U.S. human consumption; and an area of agricultural land equal to California and New York.

How much co2 does 1kg of food waste produce? ›

Putting it into perspective. The 1.3 gigatons of edible food wasted releases 3.3 gigatons equivalent of carbon dioxide (CO2), meaning that for every 1kg of food waste, just over 2.5kg of CO2 is emitted.

How much does food waste contribute to climate change UK? ›

The greenhouse gas emissions associated with the 9.5 million tonnes of food waste in the UK in 2018 have been estimated to be around 36 million tonnes of carbon dioxide equivalent (CO2e), according to the latest report from Waste and Resources Action Programme (WRAP), which collects the UK food waste data.

How is food waste affecting the environment? ›

Impacts include: greenhouse gas emissions of more than 42 coal-fired power plants; enough water and energy to supply more than 50 million homes; the amount of fertilizer used in the U.S. to grow all plant-based foods for U.S. human consumption; and an area of agricultural land equal to California and New York.

How much does food waste contribute to greenhouse gas emissions? ›

Food losses and waste – in supply chains and by consumers – account for around one-quarter of greenhouse gas emissions from food. That's 6% of total global emissions.

Which meat has lowest carbon footprint? ›

#1 Turkey and Chicken

If you want to minimise your carbon footprint without giving up meat, chicken is your best option. Chicken produces 2.33 kg of C02 per kg of meat before transport and processing. There are issues with slaughter and processing though.

Which food has the highest carbon footprint? ›

Beef has the highest carbon footprint of any food. This is because of what is required to raise and farm cattle. Animals used for beef production require a tremendous amount of feed, which must be grown on its own.

Does eating less meat reduce your carbon footprint? ›

By eating less beef, we can start to decrease that demand. You do not have to become a vegan to do this. According to one recent study, if every person in the U.S. cut their meat consumption by 25 percent, it would reduce annual greenhouse gas emissions by 1 percent.

How does waste disposal affect climate change? ›

Our Wasteful Impact on Climate Change

Solid waste contributes directly to greenhouse gas emissions through the generation of methane from the anaerobic decay of waste in landfills, and the emission of nitrous oxide from our solid waste combustion facilities.

What is the biggest contributor to food waste? ›

Agricultural production, at 33 percent, is responsible for the greatest amount of total food wastage volumes.

How will food waste affect the future? ›

With over a third of the world's food going in the trash, food waste has become a major problem. Carbon emissions and methane gas caused by decomposing food waste in landfills, not to mention the impact of trucking significant amounts of waste, is contributing to climate change and environmental decay.

Why food waste management is important? ›

Poor management of food waste causes the loss of natural resources, human health issues, pollution of rivers and seas, the generation of methane emissions from dumps and landfills, and a missed opportunity to recover valuable energy, organic matter, nutrients and water contained in food waste.

Is food waste getting better or worse? ›

Not only do we waste more than the global average, but the amount of food we waste has tripled over the past 50 years, increasing at a faster rate than our population.

The idea that one man’s trash is another’s treasure has been thrown around for decades, but could taking it literally help to tackle food waste?

While recognising the potential to convert food waste to bioenergy and compost, Bos-Brouwers says it shouldn’t be the first resort.. White explained: “You could take potato peel, burn it and get a little bit of energy.. Food waste occurs at production, retail and consumer levels and the circular economy approach can be integrated at all stages.. Bos-Brouwers noted that innovations also happen where supply chain partners meet up.. They founded a company that repurposes retail and food processors surplus into marketable products.. Instilling trust in new approaches to food waste can also be challenging.. While finding new destinations for unavoidable food waste is celebrated, food waste prevention when possible is preferable.. Legislation is also very important.

Over a third of all food produced globally goes to waste, that's 1.3 billion tonnes every year. Find out which circular economy companies are tackling the problem head on and how.

Of course, in addition to the food waste itself, there’s plenty of non-food waste generated by the food industry in the form of CO2 emissions and packaging.. It’s a shocking fact that a third of all food produced globally goes to waste .. Put another way, that’s $1 trillion worth of food going to waste annually, or 1.3 billion tonnes.. Less than a quarter of the food wasted in the US, UK and Europe could feed all the hungry people in the world - nearly a billion of them.. So isn’t the pressure on food production a big enough issue without the extreme waste?. Reduce the waste and reduce the pressure and, at the same time, reduce the food industry’s adverse effects on the planet—sounds obvious.. It’s more than just what we see as consumers: more than just food on shelves going unsold and then going past its sell by date, or food we’ve bought going off in our fridges and cupboards and being thrown away uneaten.. At the point of production, this has to suggest it’s cheaper for the producer to waste than to prevent the waste.. We can fill up our food waste kitchen caddy and start a compost heap.. Oddbox is a similar idea for fruit and veg, allowing you to “Rescue odd and surplus fruit and veg directly from the farm and help save the planet.” Winnow , meanwhile, provides artificial intelligence solutions to the hospitality industry, cleverly assessing which food types are going to waste and allowing kitchens to save money as well as reduce food waste.. A company called nibs etc uses waste carrot, apple and ginger pulp to make new food products, such as granola.. One of the bigger names in the food waste reduction game is Olio , a free app that connects people who have food (and other things) they don’t want or need, with nearby neighbours who can make use of it.. Olio founders Tessa Clarke and Saasha Celestial-One point out that in developed countries half of all food waste takes place in the home.. As these innovative companies are showing, it’s possible that a circular approach can remedy many of the challenges with waste in today’s food industry.

Furthermore with the European Commission, governments, universities and practitioner organisations embracing the circular economy, a question remains over how its implementation can actually address the problems caused by over-consumption whilst contributing towards more sustainable and equitable societal development.. Reducing food waste has the potential to save resources, reduce pollution and increase food security, for example by feeding 12.5% of the world’s malnourished people (FAO, 2012).. How therefore can the circular economy help with this problem?. Such actions aim to reduce the amount of waste existing beyond the consumer whilst ensuring as much surplus food as possible is directed towards human consumption rather than recovery or disposal actions.. Wefood in Copenhagen collects donated surplus food (edible food waste) from retailers and sells it at reduced prices in its stores.. WRAP as a leader in disseminating such messages through their ‘love food hate waste’ campaign, note that the average family throws away £700 per year worth of food (WRAP, 2017a).. The greater question here perhaps underpinning the momentum of the circular economy is whether such prevention, re-use, recycle, recovery and efficiency actions are sufficient to offset the increasing use of resources and furthermore the degradative impacts that result from this.. New initiatives to recirculate products, such as those based upon the sharing economy, can help in reducing the consumption of new goods, and initiatives around sharing food now exist to potentially achieve a scalable impact (see the app OLIO ).. The business models highlighted here are innovative ways of dealing with surplus food but what about ensuring that there is not any surplus food in the first place?. WRAP (2017a) Household Food Waste in the UK, 2015.

One-third of all food worldwide ends up in the garbage, with industrialized countries contributing the most. A new foodsharing platform wants to help tackle the impact this has on our climate.

The online platform links more than 50,000 "food savers" with businesses that want to give away food for free instead of throwing it away.. "According to 2011 estimates, one-third of all food produced globally ends up in the garbage," says Rosa Rolle, head of the Food Loss and Food Waste Project at the Food and Agriculture Organization of the United Nations (FAO).. The FAO estimates that collectively this food waste has a CO2 footprint of 3.6 gigatons.. The majority of food waste is produced by the high-income industrialized countries.. Food that ends up in landfill sites produces climate-damaging gases into the atmosphere. Meat that is thrown away is therefore far more problematic for the environment than most plant-based foods, all the more so because 20 percent of the world's meat products end up in the bin.. "Despite some progress and good initiatives for redistribution, too much food still ends up in landfills, releasing even more climate-damaging gases into the atmosphere," says Rolle.. Regardless of whether it's bread or meat, it continues to contribute to climate change, as organic waste rots in landfills and releases methane gas.. "First and foremost, we have to try to avoid food waste," said Siebert.. Here, the gas produced by decomposing food waste can be used much more effectively than at the landfill.. One of the places where this happens is Leipzig, but for Jonas Korn and his three companions that is no reason to waste food: "Then you may as well throw the whole supermarket in the biogas plant," jokes Korn.

Eliminating food waste is economically plausible and can unleash new opportunities for businesses.

A few weeks later, Italy followed suit , banning food waste and obliging supermarkets to donate unused food to charities.. In the United States, for example, food waste per capita has increased by 50 percent since 1974 , and globally, we currently throw out three billion tons of food each year.. Food Cowboy takes this same model and focuses on truckers along the supply chain, who collect food that is still fresh but turned away by retailers, and drive it to food banks or charities that bid to receive the stock through a smartphone application.. Greater awareness of the value of food has led some companies to cut their food waste by as much as 80 percent.. Manufacturing waste and byproducts in the food industry also present opportunity in the circular economy.. But new tools such as Green Egg Shopper and Love Food Hate Waste ,—which help people keep track of what they buy and when, and offer recipe suggestions to make use of every ingredient—may help drive new consumer demand for reducing food waste.. Realize that food waste is a lost economic opportunity and detect where food waste may be occurring.. Food distributors, supermarkets, and vendors may be incurring excessive costs from food waste.

The best way to prevent waste may be to stop surpluses from occurring in the first place.

Bagged food waste amid food waste containers.Food waste is a big deal.. The waste of the money associated with producing the now wasted food.. Reducing waste at beginning of supply chain Broadly, experts more or less agree that in producing way more food than is necessary, the world is using more resources – many of them with climate change implications – than it needs to.. Emissions from the farm Berkenkamp says she thinks that most of the emissions associated with wasted food happen when animals are raised and food is grown.. “That’s not how we solve the food waste issue.” Broccoli slaw may be delicious, he said, but “it’s not going to end the climate impact of food waste.”

The French food and water company Danone has a history of environmental awareness. In this interview with McKinsey partner Clarisse Magnin, CEO Emmanuel Faber discusses his commitment to resource efficiency.

Danone’s approach rests on what we call consumption ecosystems, taking into account every stage in the life of products, from the production of raw material to the “second life” of packaging.. Emmanuel Faber: To embed the principles of the circular economy in our operations, we have started managing our three key resources—water, milk, and plastic—as cycles rather than as conventional linear supply chains.. Under a new partnership with Veolia, a global waste-management company, we are working together on building a circular economy around water and packaging waste, testing new ideas and investigating new technology.. Emmanuel Faber: At the moment, nearly 30 percent of our total packaging comes from recycled materials, and as much as 80 percent in the case of cartons, but we continue to make progress.. For plastics, the endgame could be the creation of a net-positive cycle in partnership with other large companies, which would mean recycling more plastics than we put on the market in the first place.. Our ambition is to create a second life for all the plastic packaging we put on the market, so that we move toward 100 percent recycling in this respect.. This person oversees separate internal units for the milk cycle, the water cycle, and the plastic cycle.. We have also created a Milk Technology Center that reports to the Milk Cycle Organization—part of the Strategic Resources Cycles unit—not to R&D or to the dairy business, as it might under a conventional structure.. The aim here is to achieve a step change in our ability to maximize the value of milk and limit the waste from milk production.. McKinsey: How do you change Danone’s culture to embrace circular-economy thinking?. Emmanuel Faber: Danone has circular-economy principles in its DNA, and people join Danone because of its unique culture and heritage.. We would never have made as much progress with our CO2 reduction program in 2008 if we had just gone for a 2 percent reduction per year rather than 30 percent over five years, which we set ourselves.. A few years ago, the annual incentive program for the 1,500 top managers at Danone encompassed the CO2 reduction objective, to the point where, broadly speaking, the yearly bonus attached to CO2 reduction was equivalent to the yearly bonus attached to profit generation.. On top of this, and in order to foster change with Danone’s 100,000 employees, the company launched a manifesto to underpin the way we intend to deliver on our mission.. Emmanuel Faber: Consumers are interested in what is at work in the products they eat, how these products were produced and delivered, and what is their effect on the body.

The UN’s Food and Agriculture Organization estimates that 1.3 billion tonnes of food are wasted or lost every year.

From fairs promoting healthy diets to lectures teaching students how to reduce food waste, a wide range of public events is planned for Wednesday in some 150 countries to raise awareness about tackling world hunger and highlight the challenges facing the global food supply.. The initiatives are part of World Food Day , which is marked annually on October 16, the day the Food and Agriculture Organization ( FAO ), a United Nations agency, was founded in 1945.. At the same time, an estimated 1.3 billion tonnes of food are wasted or lost annually, according to the FAO, which defines food waste as “the discarding or alternative (non-food) use of food that is safe and nutritious for human consumption”.. “We waste about one-third of the food produced for human consumption, at a cost of $990bn per year,” Inger Andersen, executive director of the United Nations Environment Programme, told Al Jazeera.. One of UN’s 17 Sustainable Development Goals ( SDGs ) set the target of halving food waste by 2030 “at the retail and consumer levels and reduce food losses along the production and supply chains, including post-harvest losses”.. According to Andersen, food waste was currently generating eight percent of greenhouse gas emissions and hence food loss and waste was a “critical tool” for nations in the fight against climate change .. “In addition to deforestation to grow foods that will never be consumed, agricultural runoff and fish farming wastes are creating dead zones in aquatic ecosystems, and food waste in landfills (waste disposal sites) is disrupting food webs, as certain predators shift towards a diet of human trash.”. Gulnihal Ozbay, a professor at Delaware State University, told Jazeera that in the United States – one of the biggest producers of food waste in the world – the “majority of material in landfill comes from food waste”.. Andersen said that “making a huge shift in household behaviour” was a major challenge in combatting the efforts to reduce food waste.. The FAO says that in middle and higher-income countries, food is wasted at later stages in the supply chain – mainly at the retail level and due to consumer behaviour.. The agency estimates that consumers in rich countries waste approximately as much food – 222 million tonnes – as the entire net food production of sub-Saharan Africa – 230 million tonnes.. Harvard professor and food law expert Emily Broad Leib told Al Jazeera it was important to encourage and teach people to how to prepare food and repurpose it, if needed.. Looking ahead, Andersen said reaching a 50 percent reduction in the next decade globally “will necessitate a nuanced understanding of the root causes of food waste in different cultures and family structures around the world”.. “Collectively, we know that food waste is a problem, but individually, we think we waste very little”, she said.. The nonprofit organization ReFED estimates that food waste generated by grocery retailers is eight million tonnes a year – while the EPA believes 23 percent of landfill waste comes directly from containers and packaging.

One of the main challenges we need to solve as soon as possible is food waste and loss. We not only need to, but the good news is, we can. The prize is not only a huge societal impact, and impact on possibly every Sustainable Development Goal, it is also an enormous economic prize. A prize for the western world, but more importantly a prize for the developing countries that of course, need it the most.

The prize is not only a huge societal impact, and impact on possibly every Sustainable Development Goal, it is also an enormous economic prize.. As much as half the food produced in developing countries never makes it to the market.. Access to education, information, transportation, and energy are some of the biggest challenges faced by smallholder farmers in developing countries at the beginning of the food chain.. By improving their access to information and education – especially for women – and providing innovative solutions to the issues of transportation and lack of access to energy, smallholder farmers can reduce their food loss.. In France, consumers also generate the most waste with 67 percent of the 7.1 billion tons of waste in the country caused by consumers.. Solutions for companies are available.

The report on global land use and agriculture comes amid accelerating deforestation in the Amazon. The report on global land use and agriculture comes amid accelerating deforestation in the Amazon.

Efforts to curb greenhouse-gas emissions and the impacts of global warming will fall significantly short without drastic changes in global land use, agriculture and human diets, leading researchers warn in a high-level report commissioned by the United Nations.. The special report on climate change and land by the Intergovernmental Panel on Climate Change (IPCC) describes plant-based diets as a major opportunity for mitigating and adapting to climate change ― and includes a policy recommendation to reduce meat consumption.. On 8 August, the IPCC released a summary of the report, which is designed to inform upcoming climate negotiations amid the worsening global climate crisis.. Unless stopped, deforestation could turn much of the remaining Amazon forests into a degraded type of desert, and could release more than 50 billion tonnes of carbon into the atmosphere in 30 to 50 years, says Carlos Nobre, a climate scientist at the University of São Paolo in Brazil.. The race to limit global warming to 1.5°C above pre-industrial levels ― the goal of the international Paris climate agreement made in 2015 ― might be a lost cause unless land is used in a more sustainable and climate-friendly way, the latest IPCC report says.. The report states with high confidence that balanced diets featuring plant-based and sustainably produced animal-sourced food “present major opportunities for adaptation and mitigation while generating significant co-benefits in terms of human health”.. So the use of biofuel crops and the creation of new forests ― seen as measures with the potential to mitigate global warming ― must be carefully managed to avoid the risk of food shortages and biodiversity loss, the report says.. About one-quarter of Earth’s ice-free land area seems to be suffering from human-induced soil degradation already ― and climate change is expected to make thing worse, particularly in low-lying coastal areas, river deltas, drylands and permafrost areas.. Since 1990, the IPCC has regularly assessed the scientific literature, producing comprehensive reports every six years or so, and special reports ― such as today’s ― on specific aspects of climate change, at irregular intervals.. A special report released last year concluded that global greenhouse-gas emissions, which hit an all-time high of more than 37 billion tonnes in 2018, must decline sharply in the very near future to limit global warming to within 1.5°C of pre-industrial levels ― and that this will require drastic action without further delay.. The IPCC’s next special report, about the ocean and ice sheets in a changing climate, is due next month .. Governments from around the world will consider the IPCC’s latest findings at a UN climate summit next month in New York.. Correction 08 August 2019 : An earlier version of the story incorrectly stated that hundreds of experts compiled the latest IPCC report.. Update 08 August 2019 : The fact that around half the experts who compiled the latest IPCC report hail from developing countries has been added to the story.

The following explores the strategies used in circular urban environments providing a glimpse into what a fully-fledged circular economy might look like.

The following explores the strategies used in circular urban environments, from architecture and construction materials to energy production, waste management and food production, as well as the processes and operations that govern these designs, providing insights into the conditions that inform circularity.. The circular economy is usually reduced to the 3Rs -Reduce-Reuse-Recycle, the concept is much more complex, presenting multiple ramifications that involve paradigm shifts in how urban environments are designed.. The strategy involves designing sustainable products, reducing waste and creating an EU market for secondary materials, among other steps.. In 2019, the city, together with Amsterdam-based organization Circle Economy , analyzed local material flows and carbon emissions in relation to the local economy to identify the key industries where circular economy practices could be introduced.. Image Courtesy of White ArkitekterBesides the policies regulating resources, products and waste management, at the urban planning level, there is a strong focus on self-sufficiency in terms of energy and food production, as well as an increased preoccupation with community involvement.. Amsterdam-based practice Space&Matter has successfully implemented circular economy principles at the neighbourhood level, capitalizing on participatory processes..

The report by the Intergovernmental Panel on Climate Change is a vital guide for governments as climate change risks grow in a world where the population is heading for 10 billion people by mid-century. Read more at straitstimes.com.

LAND USE TO BE PART OF GLOBAL CLIMATE CHANGE EFFORT The report says Earth's land surface area is a key part of the solution to reducing the risks from climate change.. It is part of a natural cycle in which carbon is produced and recycled by plants on land and organisms in the oceans as a way to regulate the climate.. "But keeping global warming to well below 2 degrees Celsius can be achieved only by reducing greenhouse gas emissions from all sectors including land and food," the IPCC says.. The report finds that there are many solutions to reduce the impacts on farmlands, including switching to less intensive farming, ecosystem conservation and land restoration, reduced deforestation, cutting food waste and switching to climate-friendly diets .. It says coordinated action to address climate change can simultaneously improve land, food security and nutrition, and help to end hunger.. FOOD SECURITY "Food security will be increasingly affected by future climate change through yield declines -especially in the tropics - increased prices, reduced nutrient quality, and supply chain disruptions," said author Priyadarshi Shukla from India.. "The conclusion that we reached from the report is that the land that we are already using could feed the world in a changing climate and even provide biomass for renewable energy and to help reduce greenhouse gas emissions.. That included much better land management and careful planning on where to grow energy crops for renewable energy in a way that does not harm nature or threaten food security.
