First UN Food Systems Summit seeks new recipe for healthy people and planet

Published

on

In a historic first, the United Nations will host the inaugural Food Systems Summit on Thursday, uniting global leaders in a drive to find novel ways to produce healthy fare for the world’s growing population without harming the planet.

Observers hope the event, held during the UN General Assembly in New York, will mark the start of a new era of sustainable food production and consumption.

The summit brings together governments, businesses, farmers, indigenous peoples, youth, academics and citizens to produce a detailed roadmap to a world where good food is affordable and accessible and produced with minimal damage to the natural systems that sustain life on Earth. The event is expected to yield announcements from more than 85 heads of state and government officials on all aspects of the global food systems – from school meals to food waste to unlocking agricultural innovation to deliver on climate goals.

The pledges are the result of an 18-month preparatory process during which 148 countries hosted a programme of national dialogues to develop strategies for more inclusive, resilient and sustainable food systems. Before the summit, some 93 countries submitted national pathways to reinvent their food systems.

“Over the past 18 months, as the pandemic physically pushed us apart, the Food Systems Summit brought people together through a remarkable process of global engagement,” UN Secretary-General António Guterres said ahead of Thursday’s meeting.“They united around a simple idea: food can help us accelerate actions and bring in solutions to achieve all of the Sustainable Development Goals and recover better from COVID-19.” 

The pandemic has shown how fragile and vulnerable humanity’s food systems are. According to The State of Food Security and Nutrition in the World report, 811 million were undernourished in 2020, an increase of 118 million from 2019. Conversely, UNEP’s research has found that 17 per cent of the world’s food is thrown away.

Food systems reform is critical to tackling the climate emergency. They are responsible for 70 per cent of the water extracted from nature, generate up to one-third of human-linked greenhouse gas emissions, and agriculture has been identified as the threat to 24,000 of the 28,000 species (over 86%) at risk of extinction.

In her opening address at the summit, Inger Andersen, UNEP’s Executive Director signalled a few steps to help make the shift towards a sustainable food system. These included: strengthening action around the Rio Conventions on issues such as climate change, desertification, biodiversity in agriculture and forestry; repurposing agricultural support; and addressing the increasing demand for cheaper food in wealthy countries, which is leading to intensive agriculture and moving farming further away from nature’s regenerative systems.

“We at the United Nations Environment Programme are committed to joining up with other UN agencies – as one UN – in supporting countries as they implement ambitious commitments to transform our relationship with food – for people and for the planet,” she said.

Called as part of the Decade of Action for delivery on the Sustainable Development Goals, the Food Systems Summit aims to address global challenges, such as hunger, climate change, poverty and inequality.

“Our food systems – local, regional, and global – are central to delivering this agenda,”  said Agnes Kalibata, the UN Secretary-General’s Special Envoy to the Food Systems Summit. “There is no net zero pathway for countries or communities without transformation of our food systems.”

The United Nations Environment Programme (UNEP) is playing a critical role in the transition towards sustainable food systems. UNEP is a contributor to the One Planet Network Sustainable Food Systems Programme, leading the development of a guideline for collaborative policymaking and improved governance. It is also and a member of the Transformative Partnership Platform, informing donors and policymakers and fostering innovation. UNEP is also the custodian of the food waste element of SDG 12.3, which aims to halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains.

2021 joins top 7 warmest years on record

Published

on

Last year joined the list of the seven warmest years on record, the UN weather agency said on Wednesday, and was also the seventh consecutive year when the global temperature has been more than 1°C above pre-industrial levels; edging closer to the limit laid out under the 2015 Paris Agreement on Climate Change.

Although average global temperatures were temporarily cooled by the 2020-2022 La Niña events, 2021 was still one of the seven warmest years on record, according to six leading international datasets consolidated by the World Meteorological Organization (WMO).

Global warming and other long-term climate change trends are expected to continue as a result of record levels of heat-trapping greenhouse gases in the atmosphere, the agency said.

The average global temperature in 2021 was about 1.11 (± 0.13) °C above the pre-industrial era levels. The Paris Agreement calls for all countries to strive towards a limit of 1.5°C of global warming through concerted climate action and realistic Nationally Determined Contributions – the individual country plans that need to become a reality to slow down the rate of heating.

WMO said that it uses six international datasets “to ensure the most comprehensive, authoritative temperature assessment”, and the same data are used in its authoritative annual State of the Climate reports.

Since the 1980s, each decade has been warmer than the previous one, said WMO and “this is expected to continue.”

The warmest seven years have all been since 2015; the top three being 2016, 2019 and 2020. An exceptionally strong El Niño event occurred in 2016, which contributed to record global average warming.

“Back-to-back La Niña events mean that 2021 warming was relatively less pronounced compared to recent years. Even so, 2021 was still warmer than previous years influenced by La Niña”, said WMO Secretary-General, Prof. Petteri Taalas.

Undeniable trend

“The overall long-term warming as a result of greenhouse gas increases, is now far larger than the year-to-year variability in global average temperatures caused by naturally occurring climate drivers”.

The year 2021 will be remembered for a record-shattering temperature of nearly 50°C in Canada, comparable to the values reported in the hot Saharan Desert of Algeria, exceptional rainfall, and deadly flooding in Asia and Europe as well as drought in parts of Africa and South America”, the WMO chief added.

Climate change impacts and weather-related hazards had life-changing and devastating impacts on communities on every single continent”, Mr. Taalas underscored.

Others key indicators of global heating include greenhouse gas concentrations, ocean heat content, ocean pH levels (levels of acidity), global mean sea level, glacial mass and the extent of sea ice.

WMO uses datasets – which are based on monthly climatological data from observing sites and ships and buoys in global marine networks – developed and maintained by the US National Oceanic and Atmospheric Administration (NOAA), NASA’s Goddard Institute for Space Studies (NASA GISS), the United Kingdom’s Met Office Hadley Centre, and the University of East Anglia’s Climatic Research Unit (HadCRUT); and the Berkeley Earth group.

WMO also uses reanalysis datasets from the European Centre for Medium Range Weather Forecasts and its Copernicus Climate Change Service, and the Japan Meteorological Agency (JMA).

WMO said that the temperature figures will be incorporated into its final report on the State of the Climate in 2021, which will be issued in April this year.

This will reference all key climate indicators and selected climate impacts, and updates a provisional report issued in October 2021 ahead of the COP26 climate conference in Glasgow, Scotland.

In Jamaica, farmers struggle to contend with a changing climate

Published

It’s 9 am and the rural district of Mount Airy in central Jamaica is already sweltering. As cars trundle along the region’s unpaved roads, chocolate-brown dust clouds burst from behind their back wheels. 

It is here, 50km west of Kingston and 500 meters above sea level, that the Mount Airy Farmers group are having a morning meeting. There are around two dozen people and they all say the same thing; they’re struggling to keep their plots productive amid dwindling rainfall, a byproduct of climate change.

“The weather here’s a lot drier for longer these days,” says Althea Spencer, the treasurer of the Mount Airy Farmers group, which is based in Northern Clarendon. “If  you don’t have water, it makes no sense to plant seeds because they will just die.”

The farmers though, have recently gotten some help in their search for water.

Just meters from where they are gathered stands a two-storey shed with a drainpipe on the roof that funnels rainwater into a tall, black tank. It’s one of more than two dozen reservoirs dotted across these mountains. They are part of a project backed by six United Nations (UN) bodies to help Mount Airy’s farmers adapt to climate change.

“This partnership among the UN and with communities is exactly the type of activity needed to address the day-to-day and practical impacts of climate change,” says Vincent Sweeney, Head of the Caribbean Sub-Regional Office at the United Nations Environment Programme (UNEP). “As we look beyond the Glasgow Climate Change Conference, it is vital that we… adapt to the new realities of a warmer planet in order to protect lives and livelihoods in Jamaica and the Caribbean.”

The challenge is not unique to the region. Droughts, floods, and the spread of pests, the byproducts of climate change, are threatening agricultural production around the globe, says the Food and Agriculture Organization. That is potentially disastrous in a world where almost 700 million people go hungry each year.

Small-hold farmers, who work more than 80 per cent of the world‘s farms, in particular, will need support to remain resilient in the face of climate change, say experts.

A country at risk

Farmers in Jamaica, an island nation of 3 million, are especially vulnerable. In 2020, Jamaica became the first Caribbean country to submit a tougher climate action plan to the UN because the country was at risk from rising sea levels, drought and more intense hurricanes, its government said.

In 2018, the Mount Airy farmers enrolled in the United Nations-backed programme that helps build the resilience of communities to threats such as climate change, poverty and water insecurity. It is regarded as the first joint programme of the United Nations  in Jamaica, combining the resources of six agencies, including UNEP.

In Mount Airy, the UN programme has invested in 30 new water harvesting systems. The large, black tanks, which appear across the hilltops like turrets, catch and store rainfall, allowing the farmers to use it evenly via a drip irrigation system. This reduces the emerging threat of longer and more intense dry spells.

The new irrigation system also frees farmers from watering their crops by hand. “Before we got the new system, you had to predict rainfall to put seedlings in,” says Spencer, a rollerball pen tucked neatly into her hair and her feet shifting on the sunbaked earth. “It feels pretty good. It allows me more time to do housework, keep up with my farm records, and I have time to go down to the market.” 

Alongside the tanks sit drums which mix fertilizer with water and spread it evenly among the crops, saving the farmers valuable time. The dissolvable fertilizer is also cheaper than standard fertilizers.

On top of that, the irrigation system improves yields. Spencer now grows and sells more sweet potatoes, peppers and tomatoes than ever before.  

Coupled with the water tanks, the programme has also prioritized education. Seminars are run by the Rural Agricultural Development Authority, a government agency, which aims to broaden the farmer’s knowledge and skills. 

Although it is not unusual for women to farm these lands, Spencer speaks about how the trainings have helped to empower the female members of the group by coming together. “To me, the learnings and the trainings bond us ladies together,” she says. 

A life in the mountains

Back at the gathering of the Mount Airy farmers, the assembled say some prayers and repeat their mantra aloud two times: “We are the Mount Airy Farmers Group our motto is: All grow in fear and failure bearing fruits of confidence and success.”

Spencer, who is in her 40s, is a vocal participant at the meeting and obviously well-liked. She was born in Mount Airy and has been farming these fields most of her life. She has vivid memories of working on her father’s farm as a child. Unable to afford to pay anyone else, he often pulled her out of school to sow and reap the fields.

That’s a common refrain among many who grew up in Mount Airy – and one the new UN programme is aiming to change. 

“If my father had this harvesting system, would I have gone to school more?” Spencer asks herself. “Yes, probably. But even then, he was always working us. So I’m sure he’d find something for us to do,” she says laughing. 

Spencer welcomes the introduction of the water tanks. However, she says current rainfall patterns mean water sometimes still runs out. “If you don’t manage your water properly, one will run out before you get anywhere,” she says ominously.

Her story may be one of success today, but it shows that living with climate change will require adaptation and continued investment for years to come. UNEP’s 2021 Adaptation Gap Report called for an urgent increase in financing for climate adaptation. It found that adaptation costs in developing countries are five to ten times greater than current public adaptation finance flows, and the adaptation finance gap is widening.

Climate change: For 25th year in a row, Greenland ice sheet shrinks

Published

on

2021 marked the 25th year in a row in which the key Greenland ice sheet lost more mass during the melting season, than it gained during the winter, according to a new UN-endorsed report issued on Friday. 

The data from the Danish Arctic monitoring service Polar Portal – which forms part of the UN weather agency WMO’s annual State of the Climate report – shows that early summer was cold and wet, with unusually heavy and late snowfall in June, which delayed the onset of the melting season. 

After that, however, a heatwave at the end of July, led to a considerable loss of ice. 

In terms of “total mass balance” (the sum of surface melting and loss of ice chunks from icebergs, in addition to the melting of glacier “tongues” in contact with seawater), the ice sheet lost around 166 billion tonnes during the 12-month period ending in August 2021. 

Climate change 

These numbers mean the ice sheet ended the season with a net surface mass balance of approximately 396 billion tonnes, making it the 28th lowest level recorded, in the 41-year time series.  

This could be considered an average year, but Polar Report notes how perspectives have changed, due to rapidly advancing climate change. 

At the end of the 1990s, for example, these same figures would have been regarded as a year with a very low surface mass balance. 

The report also notes that the cause of the early summer chill, could be due to conditions over southwest Canada and the northwest United States. 

In these territories, an enormous “blocking” high pressure system was formed, shaped like the Greek capital letter Omega (Ω). 

This flow pattern occurs regularly in the troposphere, and not just over North America, but it had never been observed with such strength before. 

According to the report, an analysis by World Weather Attribution demonstrated that it could only be explained as a result of atmospheric warming caused by human activity. 

Notable year 

According to the report, 2021 was notable for several reasons. 

It was the year in which precipitation at Summit Station, which is located at the top of the ice sheet at an altitude of 3,200 metres above sea level, was registered in the form of rain. 

The year also saw an acceleration of the loss of ice at the Sermeq Kujalleq glacier, where the rate of loss had otherwise been stagnant for several years. 

Winter snowfall was also close to average for the period between 1981 and 2010, which was good news, because a combination of low winter snowfall and a warm summer can result in very large losses of ice, as was the case in 2019.
