A United Nations summit on the state of the world’s food systems opens today in Rome, Italy, a gathering that comes amid mounting concerns about the planet’s long-term ability to feed a fast-growing human population.

At the UN Food Systems Summit +2 Stocktaking Moment, delegates from across the planet are expected to discuss the often-devastating environmental impact of agriculture and how to make food production more sustainable.

The event is a follow-up to the 2021 UN Food Systems Summit, a landmark gathering that launched a global drive to transform the way humanity grows, processes and transports food.

To better understand what is at stake at the gathering this week, we spoke with Susan Gardner, Director of the Ecosystems Division at the United Nations Environment Programme (UNEP).

The UN Secretary-General has said the world needs to quickly overhaul the way it produces food. What are we doing so wrong?

Susan Gardner (SG): Our food systems right now are unsustainable. They are a major contributor to the triple planetary crisis of climate change, biodiversity loss and pollution. For example, agriculture alone generates about one-third of greenhouse gas emissions globally. As once-wild spaces are turned into pastures and cropland, it is also responsible for over 60 per cent of biodiversity loss. To top that all off, one-third of all food produced is wasted, needlessly taxing an already stressed planet. 

What are the long-term implications of all that?

SG: Food systems and nature are interlinked. Nature provides us with essential ecological services that make food production possible. That includes everything from pollination to pest control to water stability to soil fertility. We must stop nature’s decline,  in order to feed ourselves in the years to come.

There are 8 billion people on this planet, hundreds of millions of whom are already hungry. Is there a danger that by making dramatic changes to our food systems we might make hunger and malnutrition worse?

SG: Changes to our food systems, when done with careful planning, can actually help alleviate hunger and malnutrition. Sustainable food systems prioritize diverse and nutritious crops, local production and farming practices that can withstand climate change. By promoting things like agroecology, regenerative agriculture and sustainable fisheries, we can increase food production while preserving ecosystems. This will reduce the risk of food scarcity and improve food security for vulnerable people.

The UN Food Systems Summit in 2021 centered on making food production less damaging to the planet. This week’s gathering in Rome will focus on the progress the world has made since then. How do you think we’re doing?

SG: There is much more work yet to be done but the signs are promising. One-quarter of countries have signaled publicly that there’s a need to reform their food systems, opening an important public discourse. And over the past two years, the UN Food Systems Task Force, co-chaired by UNEP and the World Health Organization, has helped countries begin the complicated process of reforming the way they produce food. We are seeing examples of states expanding their national development plans to include strategies for transforming their food systems. Some countries have also begun considering how changes to their food systems could impact their nationally determined contributions, the targets that are at the heart of the Paris climate change agreement.

One issue likely to come up in Rome is agricultural subsidies, which have been called damaging to the planet. How can states better spend this money? 

SG: Right now,  agricultural producers receive US$540 billion a year in financial support from states. The vast majority of that – some 87 per cent – either distorts prices or is harmful to nature and human health. In 2021, UNEP published a report, along with other UN partners, that called on governments to rethink the way agriculture is subsidized. By redirecting agricultural subsidies towards sustainable practices, small-scale farmers, research and innovation, rural infrastructure and nutrition, states can foster a more equitable and resilient food system.

In policy circles, there has been much talk about Indigenous food systems and how they often provide more nutrition and are easier on the planet. But how can we translate those systems, which tend to be smaller, into a global model that can feed the world?

SG: Indigenous communities hold a wealth of knowledge that can contribute greatly to our understanding of issues, such as sustainable farming techniques and seed preservation. But despite their immense cultural value, indigenous food systems are being eroded at an alarming pace. That’s because global agricultural systems are increasingly prizing just a few staple crops, specifically maize, wheat and rice. Investing in research and development specific to indigenous food systems can unlock their potential for wider application. This includes studying traditional crop varieties for their nutritional value, drought and pest resistance, and adaptation to climate change. By combining traditional wisdom with scientific advancements, we can develop crops and farming methods that are both sustainable and scalable.

The Rome meeting has been called a “make-or-break” moment for our food systems. What does a successful Stocktaking Moment look like to you?

SG: We are at a crossroads. There is no real alternative other than a strong, coordinated response to what is a deepening crisis. There are some tangible outcomes that we would like to see emerge from the discussion in Rome. Those include commitments to data-driven agricultural best practices that promote both human and ecosystem health . We’d also like to see increased support for farmers who want to transition from monocultures to more diverse and sustainable farming systems. And, we would like to see these practices integrated into national plans for agriculture, climate change and biodiversity preservation.

Are you optimistic that the world will be able to transform its food systems, especially with the clock ticking?

SG: I am. The task ahead of us is not easy. But by working collectively we can make our food systems more sustainable and resilient to climate change. That will ultimately help us make significant progress towards the Sustainable Development Goals, creating a better future for us all.

United Nations Environment Programme Executive Director Inger Andersen recently visited the Noor power plant in Morocco, one of the largest solar facilities in the world.

Located near the town of Ouarzazate, on the edge of the Sahara Desert, the plant produces 580 megawatts of electricity, enough to power the homes of 2.3 million people.

The facility is part of a larger push by Morocco to develop clean energy and Andersen called it a “step into a greener world.

“Climate justice and access to energy go hand in hand,” said Andersen during her visit. “Let’s make sure that we show the world that [renewable energy] is entirely doable, possible and indeed feasible, and that it’s not only the right thing to do, it is very much the smart thing to do.”

On a recent Monday in late June, the mercury in Phoenix, Arizona, was set to reach 110 degrees Fahrenheit—with even hotter weather on the way. Summers in Phoenix have always been scorchers, but it wasn’t until 2021 that the city set up the Office of Heat Response and Mitigation.

“We’ve seen a really significant rise in heat-associated deaths, ” said David Hondula, the new office’s director.

Like many parts of the world, Phoenix is seeing more intense warmth driven by climate change. Across the U.S., heat waves have become longer, hotter, and more frequent in recent decades. So, it would follow that the risk of heat-related deaths and illnesses could go up, too.

But Phoenix’s increase in deaths, Hondula said, is related to socioeconomic inequities such as access to an air-conditioned home or car. He pointed to a rise in the number of unsheltered people as a key factor.

While heat waves may worsen, public health crises are preventable. That’s why many cities and states are developing early warning systems, more public education, and community resources such as cooling centers where people can escape oppressive temperatures.

For individuals, the heat safety advice may sound familiar: limit outdoor activity, especially at peak midday temperatures; stay hydrated; and cool off at a public place like a library or heat-relief shelter if you don’t have air conditioning at home.

Such tips “all sound like kind of penetrating glimpses into the obvious, but we still have to point them out, because we keep seeing people die during these extreme heat events,” said Jeremy Hess, an environmental health scientist at the University of Washington.

In the longer term, measures such as planting trees for shade and installing reflective cool roofs in certain places can help build resilience against hot weather in homes and communities. For the here and now, here’s how to keep cool.

Why is heat dangerous?

Hess recently released a report highlighting how serious, direct reactions such as heat stroke are only one health hazard from heat. Heat can exacerbate chronic conditions such as heart disease, which accounted for a quarter of heat-related deaths in the U.S. between 1999 and 2018.

“In some studies, the number of people who have chronic disease exacerbations related to heat actually outnumber the acute heat illness cases,” Hess said. Drowning accidents, too, go up during heat waves, as people head to pools and bodies of water to cool off.

Other vulnerable groups include outdoor workers, pregnant people, the elderly, children and infants, people experiencing homelessness, and those who use drugs and alcohol. About half the heat deaths in Phoenix, Hondula said, are associated with substance use.

High humidity coupled with high temperatures poses an increased danger, since the humid air makes it harder for sweat to evaporate and cool the body.

How to protect yourself 

Monitor forecasts including the heat index for your area so that you know when intense weather is coming and can plan accordingly.

If you can, limit time outdoors and avoid strenuous activity during the hottest parts of the day. Those heat index ratings? They pertain to shady areas. In direct sunlight, the value can increase up to 15°F, according to the National Weather Service.

Avoid sugar, caffeine, and alcohol in drinks, all of which will make you lose fluids. Drink plenty of water, and don’t wait until you’re thirsty to do it. Hess said electrolyte drinks can be helpful in rehydrating, especially during sustained activity, but you don’t need to seek out a certain brand: lightly salted water is good.

Either way, drink the water you have, and carry plenty with you if you’re going out in nature. For hikers in the Phoenix area, the city recommends carrying 16 to 32 ounces per hour per person.

Wear light-colored, lightweight clothes. When outside, seek shade where possible; wear sunblock; and bring a hat or parasol.

How to protect your home 

Keep blinds drawn and use window reflectors. Avoid using heat-emitting appliances like ovens and stoves. Where possible, use weather stripping and insulation to keep cool air in and hot air out. If investing in home efficiency is out of reach, investigate the Low Income Home Energy Assistance Program and similar programs in your area that might subsidize costs.

A 2019 study from the University of Sydney confirmed that using an electric fan is beneficial when it’s hot and humid, but may be harmful when it’s both very hot and very dry.

Hondula’s team used this and related research from the university’s Ollie Jay as the basis for an infographic with pros and cons of different low-cost or no-cost ways to cool down.

Soaking feet in cool water, ice towels, and wet clothing can all be effective strategies. Other ideas only work in certain conditions. Evaporative coolers (also known as swamp coolers), are cheaper than air conditioning to run, but they won’t help when it’s very humid.

Dehumidifiers may help with comfort, but don’t expect them to lower room temperatures.

What to do when things heat up 

“It’s important to recognize that heat is a really dangerous hazard when people aren’t protected from it,” Hess said.

When heat exhaustion sets in, symptoms include nausea, headache, and fatigue. At that point, experts recommend cooling down quickly to prevent heat stroke. The two major signs of heat stroke, Hess said, are an elevated body temperature and confusion or delirium. If you see these symptoms, seek immediate medical attention.

Seek a cooling center if your home gets too hot. Air conditioning is obviously effective at cooling, but not everyone has it—and for some people who do, running it may be prohibitively expensive.

“There are definitely caveats with air conditioning. It’s expensive to install, and it requires more electricity than other measures to operate,” Hess said. “In public health, we’re reluctant to emphasize air conditioning as a primary strategy.”

Places like libraries, shopping malls, or community centers can provide relief. Public cooling centers, hydration stations, and ways to reach them are all part of the effort to keep people safe in Phoenix.

“We’ll be talking to a couple living in their vehicle in a parking lot, and they didn’t realize the building right next to where they’re parked is open to go in and cool off for a couple hours,” Hondula said.

Hess noted that evenings can be a vulnerable time for elders because heat accumulates throughout the day, particularly in cities, and people may stop contact in the late afternoon, thinking that the worst of the heat has passed.

Hondula echoed this caution. “It doesn’t take very long to transition from being in a good situation to not a good situation,” he said. “We can’t check on each other too much on our hottest days.”
