Food is at the center of human lives. Not only is food is condition for our existence, it is also at the basis of our cultural norms and social lives. Food production is provides the livelihood for the 883 million people employed in the agriculture sector. As nature provides the foundation for plants to grow and animals to live, food is intrinsically connected to the environment. However, unsustainable food production and consumption practices have led to environmental degradation and exacerbated climate change. In return, food systems suffer from climate change, biodiversity loss and pollution. Learn more about these issues and the role of Geneva-based organizations to foster sustainable food systems below.

About Food Systems

The term “food system” refers to the constellation of activities involved in producing, processing, transporting and consuming food. Food systems touch every aspect of human existence. The health of our food systems profoundly affects the health of our bodies, as well as the health of our environment, our economies and our cultures. When they function well, food systems have the power to bring us together as families, communities and nations.

But too many of the world’s food systems are fragile, unexamined and vulnerable to collapse, as millions of people around the globe have experienced first-hand during the COVID-19 crisis. When our food systems fail, the resulting disorder threatens our education, health and economy, as well as human rights, peace and security. As in so many cases, those who are already poor or marginalized are the most vulnerable.

The good news is that we know what we need to do to get back on track. Scientists agree that transforming our food systems is among the most powerful ways to change course and make progress towards all 17 Sustainable Development Goals. Rebuilding the food systems of the world will also enable us to answer the UN Secretary-General’s call to “build back better” from COVID-19. We are all part of the food system, and so we all must come together to bring about the transformation that the world needs.

Food and the SDGs

As the prime connection between people and the planet, food and agriculture can help achieve multiple Sustainable Development Goals (SDGs). Of course, SDG 2 is the first one that comes to mind. This goal calls for the end malnutrition and ensure access to safe and nutritious food across the world by 2030. In 2019, an estimated 2 billion people in the world did not have regular access to safe, nutritious and sufficient food. If recent trends continue, the number of people affected by hunger will surpass 840 million by 2030, or 9.8% of the global population.

Nature provides direct sources of food and a series of ecosystem services (e.g. pollination, soil formation, nutrient cycling, and water regulation) supporting agricultural activities and contributing to food security and nutrition. Targets 2.4 and 2.5 recognize the important of the environment to achieve zero hunger. While we need to produce food for an additional two billion people by 2030 due to increasing world population, preserving and enhancing the natural resource base upon which the well-being of present and future generations depends is crucial. The unsustainable expansion of agriculture has created serious environmental problems such as soil erosion, water pollution through agrochemicals, and emission of greenhouse gases. Disasters such as droughts, landslides and floods greatly affect food security, and these will become more frequent and intense due to climate change.

Thus, environmental considerations are essential to achieve all targets of SDG2. In the long-run, only resilient food systems that work in harmony with nature will be able to provide the healthy, safe and reliable food source that we need. Food and agriculture are also intimately connected to all other SDGs. Sustainable agriculture is key to feed a growing population, while revitalizing rural landscapes, delivering inclusive growth to countries and drive positive change right across the 2030 Agenda.

World Food Day

Each year on 16 October, World Food Day reminds us that we all have a role to play to realize the vision of a world without hunger and malnutrition. We must not let sustainable habits fall by the wayside in times of crisis. We can make healthy food choices and do our part to reduce food waste. In addition, governments, enterprises, and organizations can share their knowledge and support sustainable, resilient food systems and livelihoods. Together, we can grow, nourish, and sustain our world. Find more information and related events for each edition:

UN Food Systems Stocktaking Moment 2023

The UN Food Systems Stocktaking Moment took place from 24 to 26 July 2023, in Rome, Italy, at the FAO headquarter. The event is hosted by the Italian Government in collaboration with Rome-based agencies IFAD and WFP, and the UN Food Systems Coordination Hub. Being the first global follow-up to the 2021 UN Food Systems Summit, the event will take stock of the advancements governments made since to achieve the 2030 Agenda for Sustainable Development and will highlight gaps, needs and the way forward.

Ahead of the event, regional preparatory meetings will take place. On 28 March 2023, the United Nations Food Systems Coordination Hub and the Issue-Based Coalition on Sustainable Food Systems hosted the regional preparatory meeting on the sidelines of the 2023 UNECE Regional Forum on Sustainable Development.

Food and the Triple Planetary Crisis

Climate change

The adverse impact of climate change threatens global food security and nutrition and puts at risk the agrifood systems that currently feed and nourish the great majority of the world population and support the livelihoods of more than 1 billion people. This will increasingly put pressure on food production and access to food, especially in vulnerable regions, undermining food security and nutrition and the realization of the right to food, showing climate change’s long-term and deep impact on global food insecurity.

According to the Intergovernmental Panel on Climate Change (IPCC), the impacts of climate change are already causing stress to agriculture, forestry, fisheries and aquaculture and hindering efforts to meet the global demand for food products (AR6, WGII, Chap. 5). Warming temperatures are changing the conditions for plants and insects to live, thus impacting food quality and harvest stability. Climate-related disasters, such as droughts and floods, are also affecting the productivity of the food systems, with negative consequences for food security and livelihoods. The IPCC warns that these impacts will become stronger as climate change accelerates, with some areas of the globe becoming unsuitable for agriculture. Climate change will negatively impact food safety, as it will induce changes in weeds, insect pests, pathogens, disease vectors, toxigenic fungi, and harmful algal blooms. Under worst case scenarios, climate change could put 80 million people at risk of hunger by 2050. Find the latest science on the impacts of climate change on food systems in the AR6 WGII report (2022) and the Special Report on Climate Change Land (2018).

Therefore, agrifood systems must become more resilient to the current and future impacts of climate change, learning from good practices to promote transformative adaptation policies, plans and actions, as outlined in the FAO Strategy on Climate Change. The way we produce and consume food also contributes to climate change due to the greenhouse gas emitted from the field to the plate. Farming, land use, and food supply chains are indeed large contributors to the world carbon balance. According to FAO, food systems account for more than a third of the world’s greenhouse gas emissions.

Agrifood systems featured prominently at the UN Climate Change COP28 in December 2023. One of the outcomes of the conference was the adoption of the COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action, which was signed by 159 parties. In order to keep food high on the climate agenda, FAO also launched a Global Roadmap on Achieving SDG2 without breaching the 1.5C thresholda multi-year process that will establish plans from the global to the local level to equip agrifood systems to the changing climate and decrease their impacts.

Biodiversity loss

According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), around 1 million species already face extinction worldwide, with the global rate of species extinction today being higher than the average rate over the past 10 million years. Our global food system is the primary driver of biodiversity loss, with agriculture alone being the identified threat to 24,000 of the 28,000 (86%) species at risk of extinction. While intensification of agriculture, conversion of land for agricultural purposes, and high use of fertilizers and pesticides have allowed to produce more food at a lower cost, it also came with an significant environmental cost. Therefore, fostering sustainable food systems are essential. This means moving away from monocultures, supporting agroecology and Nature-based Solutions, adopting more plant-heavy diets, and other solutions which reduce the pressure of food production on the planet.

Food production also relies on nature itself, and thus is deeply affected by biodiversity loss. Biodiversity plays an important role in underpinning ecosystem functions and services that are essential for the productivity and sustainability of our food systems. According to the latest IPBES Global Assessment report, the loss of diversity, including genetic diversity, poses a “serious risk to global food security by undermining the resilience of many agricultural systems to threats such as pests, pathogens and climate change”. Additionnally, the decrease in pollinators across the world has been identified as a key challenge for the future of food security.


Modern agriculture practices rely heavily on novel substances to increase productivity and reduce the costs of production. Chemical fertilizers, pesticides, antibiotics and plastic materials used in agriculture, livestock production, fishing and aquaculture are major drivers of water and soil pollution. The discharge of pollutants into the environment is not only a great concern for ecosystem health, but also for human health. Such pollutants include pathogens from livestock, pesticides, nitrates in groundwater, trace metallic elements and toxic chemicals, as well as antibiotics and antibiotic-resistant genes excreted by livestock. Some of these substances are regulated at the international level, for instance the Stockholm Convention reviews and bans persistent organic pollutants (POPs) such as the infamous insecticide DDT.

More recently, the impacts of plastic use in agriculture has been under scrutiny, as new research revealed that these plastics are contaminating soils and thus impacting soil health, biodiversity, and productivity. Plastic substances are also used in chemical fertilizers, adding one more layer to the mix of substances that are leaking into the environment.

Food Loss and Waste

According to the United Nations and the Food and Agriculture Organization (FAO), around 14% of food produced is lost between harvest and retail worldwide. Significant quantities are also wasted in retail and at the consumption level. According to UNEP, the world already produces enough food to feed everyone on the planet and according to the recent Food Waste Index Report 2021, over 17% of food in total is wasted.

Around 38% of total energy consumption in the global food system is also utilized to produce food that is either lost or wasted. In addition, it takes seeds, soil and the labor of farmers to produce food, not to mention the fuel that is needed to transport it. All of these resources are lost when food is wasted. Furthermore, the disposal of food loss and waste in landfills leads to greenhouse gas emissions, contributing to climate change. Policymakers can improve the chances of achieving climate goals and limiting global warming to 1.5°C by making more specific commitments to transforming national food systems.

International Day of Awareness of Food Loss and Waste Reduction

Each year on 29 September, the International Day of Awareness of Food Loss and Waste. Reducing food loss and waste is of significant importance as it contributes to the realization of broader improvements to agri-food systems toward achieving food security, food safety, improving food quality and delivering on nutritional outcomes. Reducing food loss and waste also contributes significantly to the reduction of greenhouse gas emissions, as well as pressure on land and water resources.

Action for Better Food Systems

Reducing food waste and shifting dietary patterns could reduce anthropogenic greenhouse gas emissions from the food system by as much as 50%. In addition, restoring biodiversity could strengthen the resilience of food systems, enabling farmers to diversify production and cope with pests, diseases and climate change.

Nature-based Solutions (NbS)

Food production has a massive impact on our planet. Moreover, looking forward, global food production needs are expected to increase more than 40% by 2030 and 70% by 2050, compared to average 2005-07 levels, according to OECD and FAO. With more than half of Earth’s habitable lands currently used for agriculture, farmers and food producers play an important role in maintaining and conserving biodiversity. The loss of healthy soils reduces agricultural yields and could result in a food production shortfall of 25% by 2050. In addition, according to the International Union for Conservation of Nature (IUCN), it is estimated that increasing soil biodiversity could contribute up to 2.3 billion tons of additional crop production per year, valued at USD 1.4 trillion.

Leading experts at the Nature-based Solutions and Food Dialogue conducted by the Geneva Environment Network and IUCN discussed why NbS represent a key pathway for achieving this goal while contributing to established international and global targets. Adopting NbS approaches to better our food systems is essential to meeting the fundamental human right to food and contribute to multiple imperatives of the 2030 Sustainable Development Agenda.

Addressing Food Loss and Waste

According to UNEP, the world already produces enough food to feed everyone on the planet. As the recent Food Waste Index Report 2021 indicated, over 17% of food is wasted. Food waste accounts for up to 10% of global greenhouse gas emissions. It can occur at the consumer end, where food is thrown away, or as post-harvest loss – in storage, transport, packaging, or other stages before food reaches the table. UNEP found that the global average of 74 kg per capita of food wasted each year is similar from lower-middle-income to high-income countries, which means that most countries have room to improve.

Shifting Diets

Dietary habits represent another intervention area. Over the past 50 years, diets have become increasingly homogenous, dominated by crops that are rich in energy but poor in macronutrients. Of the thousands of plants and animals used for food in the past, less than 200 currently contribute to global food supplies and just nine crops account for almost 70% of all crop production. In many cases –particularly in developing countries – people do not receive the full range of nutrients essential to human health. In fact, low dietary diversity has surpassed caloric insufficiency as the primary driver of death. According to WWF, eating a planet-based diet is high in human health benefits and low in environmental impacts. Adopting a planet-based diet can reduce greenhouse gas emissions by at least 30%, wildlife loss by up to 46%, agricultural land-use by at least 41% and premature deaths by at least 20%.  Individual consumer choices must be backed up by solid and transparent facts over the climate and environmental impacts of products. To protect buyers and ensure environmental claims to be “transparent and verifiable”against greenwashing, for instance, in March 2023 the European Commission presented a proposal on green claims.

Addressing Inequalities

Marginalization, unequal access to tools, decision-making power and finance contribute to weaken agrifood systems. Indigenous peoples as well as well play key roles in agrifood systems and in finding solutions to the many challenges posed by the triple planetary crisis. A recent report by FAO found that crackling gender inequalities in agrifood systems and empowering women reduces hunger, boosts the economy, and reinforces resilience to shocks like climate change and the COVID-19 pandemic. Closing the gender and wage gaps in agrifood systems could increase global gross domestic product by nearly $1 trillion and reduce the number of food-insecure people by 45 million (FAO, 2023)

Ensuring Decent Work Conditions

Agri-food jobs are among the most hazardous, unprotected and poorly paid. Two-thirds of those workers classified as ‘extremely poor’ are in agriculture. In some countries, agricultural workers are excluded from general labor legislation. They may therefore lack the rights and legal protections available to workers in other sectors. To address this issue, the International Labour Organization (ILO), the International Fund for Agricultural Development (IFAD), and CARE International joined forces in a multi-stakeholder partnership to advance labour and human rights, decent jobs and fair and adequate incomes and wages within the agri-food sector, The Decent Work in Food Systems.
