How food waste is trashing the planet

Published

on

18 June is Sustainable Gastronomy Day, an international celebration of local cuisine that is produced in ways that are both environmentally friendly and minimize waste. That last part is becoming increasingly important. A recent report from the United Nations Environment Programme (UNEP) found the world is in the grip of an epidemic of food wastage. In 2019, consumers tossed away nearly a billion tonnes of food, or 17 per cent of all the fare they bought.

That is deeply problematic in a world where 690 million people were undernourished in 2019, a number expected to rise sharply with COVID-19. It’s also bad for the planet. Some 10 per cent of all greenhouse gas emissions come from producing food that is ultimately thrown away.

UNEP recently sat down with two of the authors of the 2021 Food Waste Index Report: Clementine O’Connor, food systems expert with UNEP, and Tom Quested, an analyst with the non-profit organization WRAP. They talked about what the world can do to end the scourge of food waste.

UNEP: What are the main findings of the 2021 Food Waste Index Report?

Tom Quested: A staggering 17 per cent of all available food for human consumption is wasted. If you can picture 23 million fully-loaded 40-tonne trucks – bumper-to-bumper, enough to circle the Earth seven times – then that’s what we’re talking about. The report estimates that, in 2019, 61 per cent of food waste was generated by households, 26 per cent from food service and 13 per cent from retail.

UNEP: Why does food waste matter?

Clementine O’Connor: Even before COVID-19, some 690 million people in the world were undernourished. Three billion people are unable to afford a healthy diet. Uneaten food is a sheer waste of energy and resources that could be put to better use. Reducing food waste at the retail, food service and household levels can provide multi-faceted benefits for people and the planet. Up to now, the opportunities provided by food waste reductions have remained largely untapped and under-exploited.

UNEP: Is this a rich-world problem, or is it more widespread?

O’Connor: An important finding of the study is that household per capita food waste is broadly similar across country income groups (as defined by the World Bank), suggesting that action on food waste is equally relevant in high and middle-income countries. This breaks significantly with the narrative of the previous decade that household food waste is a rich country problem – and underlines the need for middle-income countries to measure baselines and develop national food waste prevention strategies. Providing technical support to help countries get started, UNEP is now launching Regional Food Waste Working Groups in Latin America and the Caribbean, Africa, West Asia, and Asia-Pacific.

UNEP: What are the key data gaps?

Quested: Most governments around the world have not collected sufficiently robust data to make the case for action. Even fewer have the data to track trends in food waste over time. However, there have been a growing number of national estimates of food waste in recent years. Areas with higher data coverage include Europe, North America, Australia and New Zealand. In contrast, North Africa, Central Asia, Melanesia, Micronesia, Polynesia and the Caribbean have no available estimates.  Data in the retail and food service sectors is also much more limited than for households. As measurement is an important early step to taking action on this important issue, much more measurement is needed.

UNEP: What’s the difference between food waste and food loss?

O’Connor: Food loss occurs along the food supply chain from harvest up to, but not including, the retail level. Food waste occurs at the retail, food service and consumption levels.

UNEP: How does food waste undermine sustainable development?

Quested: Food waste generates all the environmental impacts of food production (intensive use and pollution of land and water resources, exacerbation of biodiversity loss, greenhouse gas emissions) without any of the benefits of feeding people. Food waste, therefore, undermines sustainable development. Sustainable Development Goal 12, Target 12.3, aims at halving per capita global food waste at the retail and consumer levels and reducing food losses along production and supply chains, including post-harvest losses by 2030.

UNEP: Why should I reduce my food waste? How can I get started?

O’Connor: Reducing food waste at home is one of the easiest ways to reduce your personal climate impact. You eat – and make food decisions – at least three times a day. Some easy ways to get started:

Buy only as much as you need: check your fridge before you buy groceries (or add to your online shopping cart as you notice something is missing) to avoid impulse purchases. If you can, buy fresh food regularly and top-up when needed, rather than trying to get accurate quantities in one bulk shop.

Use what you buy: get portion sizes right by using a cup measure for rice, couscous or pasta. Cook creatively with leftovers: many recipes are flexible enough to absorb any wilting vegetables at the bottom of your fridge. Most leftovers will go into a taco, a sandwich, a curry, a frittata or a pasta sauce, and will be transformed with a sauce or relish. Chefs are increasingly keeping food waste prevention in mind when they share new recipes. Make good use of your freezer: food can be frozen until its expiry date or if it still looks tasty, if it doesn’t have a date. When you get back into a restaurant, you’re on the right side of history when you ask for a smaller portion or a doggy bag, so don’t hesitate to do so.

How will you be tracking progress?

O’Connor: Food waste data in relation to SDG 12.3 will be collected using the United Nations Statistics Division/UNEP Questionnaire on Environment Statistics. The questionnaire is sent out every two years to National Statistical Offices and Ministries of Environment, which will nominate a single food waste focal point in the country to coordinate data collection and reporting. The data will be made publicly available in the SDG Global Database and in UNEP’s Food Waste Index Report, which will be published at regular intervals up to 2030. The next questionnaire will be sent to Member States in September 2022, and results will be reported to the SDG Global Database by February 2023.

No pathway to reach the Paris Agreement’s 1.5˚C goal without the G20

Published

on

“The world urgently needs a clear and unambiguous commitment to the 1.5 degree goal of the Paris Agreement from all G20 nations”, António Guterres said on Sunday after the Group failed to agree on the wording of key climate change commitments during their recent Ministerial Meeting on Environment, Climate and Energy.

“There is no pathway to this goal without the leadership of the G20. This signal is desperately needed by the billions of people already on the frontlines of the climate crisis and by markets, investors and industry who require certainty that a net zero climate resilient future is inevitable”, the Secretary General urged in a statement.

The UN chief reminded that science indicates that to meet that ‘ambitious, yet achievable goal’, the world must achieve carbon neutrality before 2050 and cut dangerous greenhouse gas emissions by 45 % by 2030 from 2010 levels. “But we are way off track”, he warned.

The world needs the G20 to deliver

With less than 100 days left before the 2021 United Nations Climate Conference COP 26, a pivotal meeting that will be held in Glasgow at the end of October, António Guterres urged all G20 and other leaders to commit to net zero by mid-century, present more ambitious 2030 national climate plans and deliver on concrete policies and actions aligned with a net zero future.

These include no new coal after 2021, phasing out fossil fuel subsidies and agreeing to a minimum international carbon pricing floor as proposed by the International Monetary Fund (IMF).

“The G7 and other developed countries must also deliver on a credible solidarity package of support for developing countries including meeting the US$100 billion goal, increasing adaptation and resilience support to at least 50% of total climate finance and getting public and multilateral development banks to significantly align their climate portfolios to meet the needs of developing countries”, he highlighted.

The UN Chief informed that he intends to use the opportunity of the upcoming UN General Assembly high-level session to bring leaders together to reach a political understanding on these critical elements of the ‘package’ needed for Glasgow.

A setback for Glasgow

The G20 ministers, which met in Naples, Italy on July 23-25, couldn’t agree to a common language on two disputed issues related to phasing out coal and the 1.5-degree goal, which now will have to be discussed at the G20 summit in Rome in October, just one day before the COP 26 starts.

Western Indian Ocean region has declared 550,000 square kilometers as protected

Published

on

The Western Indian Ocean region has declared 143* marine and coastal areas as protected – an area covering 553,163 square kilometers, representing 7 percent of the total Exclusive Economic Zone (EEZ) for the region – according to a new publication by the UN Environment Programme (UNEP)-Nairobi Convention and the Western Indian Ocean Marine Science Association.

The Marine Protected Areas Outlook, released today, indicates that almost half of the total area – an estimated 63 percent of the overall square kilometers – was brought under protection in the seven years since the 2015 adoption of Sustainable Development Goal 14.5, which committed countries to conserving at least 10 percent of their marine and coastal areas by 2020.

This Outlook examines the current and future status of Marine Protected Areas (MPAs) in Comoros, Kenya, France (in its Western Indian Ocean territories), Madagascar, Mauritius, Mozambique, Seychelles, South Africa, and Tanzania, emphasizing the increased commitment of countries to strengthen marine protection. In 2019 alone, Seychelles brought 30 percent of its Exclusive Economic Zone under protection, safeguarding the habitats of 2,600 species, while South Africa declared 20 new MPAs – enabling both countries to exceed the 10 percent target. Comoros has developed new MPA-specific legislation, while over three hundred Locally Managed Marine Areas – i.e., areas in which coastal communities shoulder the mantle of conservation – have been declared across the region.

The publication further documents the dozens of proposed MPAs currently under consideration by countries, which would cover an additional 50,000 square kilometers or more. Nevertheless, with only 7 percent of the region’s total EEZ under protection, greater momentum and investments will be required by countries to reach the more ambitious target of 30 percent protection by 2030, as proposed under the Global Biodiversity Framework.  

Although the ocean provides us with resources essential for survival, including food, employment, and even oxygen, the world is damaging and depleting it faster than ever. Soon, the region may no longer be able to count on the many jobs, health, and economic benefits – valued at 20.8 billion USD – that the Western Indian Ocean provides. Marine protected areas offer one of the best options to reverse these trends. 

“A well-managed MPA can bring significant economic, social, and environmental benefits to a country,” said Yamkela Mngxe, Acting Director of Integrated Projects and International Coordination in South Africa’s Department of Forestry, Fisheries and the Environment. “They can increase food security by preventing the overexploitation of fish stocks; create and protect jobs in the tourism and fisheries sectors; build resilience to climate change; and protect species and habitats.”

Though countries in the region have made significant strides in protecting its marine and coastal areas, the Outlook outlines best practices, challenges, and several opportunities to build on thisprogressto ensure the entire region meets future Global Biodiversity Framework targets on marine protected areas. The Outlook’s assessment of the management effectiveness of MPAs indicates that MPA frameworks and institutions do not always function effectively. Nor is relevant legislation consistently implemented, due to financial or personnel capacity gaps; weak enforcement on MPA boundaries; and management decisions that are not guided by science.

Key recommendations from the Outlook therefore include:

  1. The need for dedicated budgets for MPA management;
  2. Adopting proactive law enforcement and compliance strategies to ensure MPA regulations and guidelines are being respected which could be informed by the best practices in fishery reserves like Mauritius, which have helped to restore fish stocks and protect biodiversity;
  3. Incorporating research and monitoring programmes on biodiversity and ecosystems into decision-making in MPAs;
  4. Strengthening community engagement in marine protection by implementing lessons learned by the MIHARI Network, which brings together more than 200 Locally Managed Marine Areas in Madagascar.

“The MPA Outlook comes at a time when the region has embarked on large-scale socio-economic developments that are equally exerting pressure on MPAs,” said Hon. Flavien Joubert,Minister of Agriculture, Climate Change, and Environment of the Seychelles. “The Outlook thus provides some answers and innovative approaches to minimize the scale of negative impacts on MPAs.”

The MPA Outlook concludes that by seizing the opportunities it presents, countries in the region can capitalize on this progress to safeguard the Western Indian Ocean’s immense natural beauty and resources for generations to come – and sustain momentum towards achievement of the post 2020 biodiversity framework targets.

Deadly flooding, heatwaves in Europe, highlight urgency of climate action

Heavy rainfall that has triggered deadly and catastrophic flooding in several western European countries, is just the latest indicator that all nations need to do more to hold back climate change-induced disasters, the World Meteorological Organization (WMO) said on Friday.

The agency said that countries including Belgium, Germany, Luxembourg and the Netherlands had received up to two months’ rain in two days from 14 to 15 July, on ground that was “already near saturation”.

Photos taken at the scene of some of the worst water surges and landslides show huge, gaping holes where earth and buildings had stood until mid-week, after media reports pointed to well over 100 confirmed fatalities in Germany and Belgium on Friday morning, with an unknown number still missing across vast areas.

“We’ve seen images of houses being…swept away, it’s really, really devastating”, said WMO spokesperson Clare Nullis adding that that the disaster had overwhelmed some of the prevention measures put in place by the affected developed countries.

In a statement issued by his Spokesperson, the UN Secretary-General António Guterres, said he was saddened by the loss of life and destruction of property. “He extends his condolences and solidarity to the families of the victims and to the Governments and people of the affected countries.”

The UN chief said the UN stood ready to contribute to ongoing rescue and assistance efforts, if necessary.

“Europe on the whole is prepared, but you know, when you get extreme events, such as what we’ve seen – two months’ worth of rainfall in two days – it’s very, very difficult to cope,” added Ms. Nullis, before describing scenes of “utter devastation” in Germany’s southwestern Rhineland-Palatinate state, which is bordered by France, Belgium and Luxembourg.

Highlighting typical preparedness measures, the WMO official noted In Switzerland’s national meteorological service, MeteoSwiss, had a smartphone application which regularly issued alerts about critical high-water levels.

The highest flood warning is in place at popular tourist and camping locations including lakes Biel, Thun and the Vierwaldstattersee, with alerts also in place for Lake Brienz, the Rhine near Basel, and Lake Zurich.

Dry and hot up north

In contrast to the wet conditions, parts of Scandinavia continue to endure scorching temperatures, while smoke plumes from Siberia have affected air quality across the international dateline in Alaska. Unprecedented heat in western north America has also triggered devastating wildfires in recent weeks.

Among the Scandinavian countries enduring a lasting heatwave, the southern Finnish town of Kouvola Anjala, has seen 27 consecutive days with temperatures above 25C. “This is Finland, you know, it’s not Spain, it’s not north Africa,”, Ms. Nullis emphasised to journalists in Geneva.

“Certainly, when you see the images we’ve seen in Germany, Belgium and the Netherlands this week it’s shocking, but under climate change scenarios, we are going to see more extreme events in particular extreme heat,” the WMO official added.

Troubled waters

Concerns persist about rising sea temperatures in high northern latitudes, too, Ms. Nullis said, describing the Gulf of Finland in the Baltic Sea at a “record” high, “up to 26.6C on 14 July”, making it the warmest recorded water temperature since records began some 20 years ago.

Echoing a call by UN Secretary-General António Guterres to all countries to do more to avoid a climate catastrophe linked to rising emissions and temperatures, Ms. Nullis urged action, ahead of this year’s UN climate conference, known as COP26, in Glasgow, in November.
