Uncover the Skinny: What’s the Skinny on Famine?

With the release of the latest food security report from the Integrated Phase Classification (IPC) on war-ravaged Gaza since December, World Food Programme (WFP) chief economist Arif Husain walked UN News through the process.

What is the threshold for famine?

Famine is essentially a technical term, referring to a population that faces widespread malnutrition and hunger-related deaths due to a lack of access to food. 

“We say there is a famine when three conditions come together in a specific geographic area, whether a town, village, city, even a country,” WFP’s Mr. Husain explained.

  • At least 20 per cent of the population in that particular area are facing extreme levels of hunger;
  • 30 per cent of the children in the same place are wasted, or too thin for their height; and
  • The death – or mortality – rate has doubled, from the average, surpassing two deaths per 10,000 daily for adults and four deaths per 10,000 daily for children.

“You can clearly see that in a way, famine is admission of collective failure,” he said. “We should act way before the famine, so people don’t starve, children are not wasted and people don’t die of hunger-related causes.”

How is hunger tracked?

Famines today are different than those experienced in the 1970s or 1980s, when drought was the main driver in Ethiopia and other nations, Mr. Husain told UN News, adding that years ago, when a famine occurred, “we could say, ‘I’m sorry. I did not know. If I had known, I would have done something about it.’”

“Today, we see crises in real time, so we cannot say we did not know,” he explained. “The onus is much higher today than it has ever been before.”

Climate-related food insecurity is now closely monitored thanks to a detailed tracking system used by international humanitarian agencies wherever they work, and today, famines or risks of one developing are now largely driven by conflict, as seen in South Sudan, Yemen and now in the Occupied Palestinian Territory.

In the 21st century, climate-related famines have largely been averted thanks to an innovative tool to track acute hunger, developed during the crisis in Somalia in 2004 by the UN Food and Agriculture Organization (FAO) and now used by humanitarian agencies worldwide.

This initiative is called the Integrated Security Phase Classification, or IPC.

What is the IPC?

The IPC is an innovative multipartner initiative for improving food security and nutrition analysis and decision making.

The IPC classification and analytical approach facilitates governments, UN Agencies, non-governmental organizations, civil society and other relevant actors in working together to determine the severity and magnitude of acute and chronic food insecurity and acute malnutrition situations in a country according to internationally recognised standards.

The initiative spread has been used in more than 30 countries, and a global partnership of 19 organisations is leading the development and implementation of the IPC at global, regional and country levels.

With over 20 years of application, the IPC has proved to be one of the best practices in the global food security field.

It is also a model of collaboration in over 30 countries in Latin America, Africa and Asia.

The IPC tracks hunger but can also raise alarms ahead of potential widespread acute malnutrition before it transforms into more serious life-threatening conditions.

How does the IPC work?

The IPC itself does not collect data. The information comes from its humanitarian partners operating on the ground.

The information can cover food security, nutrition, mortality and people’s livelihoods as well as calorie intake, what kind of coping strategies people use to find food and the measurements of children’s arms to monitor malnutrition, known as the middle-upper arm circumference, or MUAC.

“Data collection does not stop, even in war zones,” Mr. Husain said.

In cases where locations are unreachable, mobile phone surveys are deployed to get information, and if that is not possible, satellites can generate information.

Technical experts from IPC partners crunch a large volume of data to better inform decision makers who can effectively address needs on the ground, with a view to avoiding a worst-case scenario.

IPC experts then gather to analyse the data, classifying populations into five categories: phase one is minimal or no stress in finding food reported; phase two sees people facing stress; phase three is a food crisis; phase four is an emergency; and phase five is considered to be a catastrophe or famine.

Based on the share of the population in each of the five phases, geographical areas are given a severity phase as well, presented by different colours on the IPC map, from the least severe to the most severe phase (minimal, stress, crisis, emergency and famine). 

Each of these geographic area phase classifications has important and distinct implications for where and how best to intervene, and therefore influences priority response objectives.

Famine Review Committee

In the case of a suspected famine, there is an additional step, which calls upon the IPC Famine Review Committee.

Comprising globally recognized experts in their fields, from nutrition and health to food security, the committee convenes when more than 20 per cent of the affected people are in IPC phase five, meaning famine or catastrophe conditions.

The consensus-based process requires all partners to agree on a conclusion that the Famine Review Committee verifies.

The committee meets and examines all the data and analyses provided by IPC partners to determine whether the findings are credible and to see whether the data justifies a famine classification or a plausible famine classification.

The experts then outline what is happening now and offer projections for the next three- or six-month periods, like in the IPC report on Gaza in December.

How aid agencies respond to hunger alerts

Humanitarian agencies use these invaluable IPC classifications to plan and to help people from the phase three crisis level onwards, with the specific goal of avoiding a famine.

“What we try to do is to get to the people, so we never have to deal with the famine like situation, or IPC phase five,” Mr. Husain said. “We work very, very hard at the crisis level and definitely at the emergency level to save people’s lives so that they don’t get to IPC phase five, which is classified as a famine.”

That includes ramping up food aid.

“When we do that, we can save lives,” he said.

‘For us, famine is the “F” word’

While needs remain high, according to WFP estimates, 309 million people in 72 countries face a level of hunger that is at the crisis level or worse. 

“For us, famine is the ‘F’ word,” Mr. Husain said, emphasizing that the end goal is prevention.

“If we are going to avoid these famines, the easiest way would be to stop the conflicts,” Mr. Husain said, “but if that is going to take time, then it is our responsibility that we are able to feed the innocent people, are able to provide the water and necessities like medicine to those people who are stuck in those places or may be displaced from those places.”

New IPC report on Gaza: Famine is ‘imminent’

The new IPC Famine Review Committee released it latest report on 18 March on the worsening situation in Gaza, where UN teams on the ground have long warned of an imminent famine against a backdrop of the ongoing Israeli military offensive in Gaza sparked by Hamas’s 7 October attacks against Israel.

Israel’s ground invasion has killed over 31,000 Gazans and, along with restrictions on aid entering the bombarded and besieged enclave, has triggered widespread hunger and growing numbers of deaths from starvation.

Since February 2024, Gaza’s entire population – 2.2 million people – had been classified at the IPC phase three crisis level or worse, the “highest share of people facing high levels of acute food insecurity that the IPC initiative has ever classified for any given area or country”, the group said.

The initial clarion call came from UN agencies and partners soon after the Israel’s October invasion following which the IPC Famine Review Committee produced its first report on Gaza at the end of 2023.

With keys drivers of food insecurity persisting, a second one was produced in March 2024. 

Here are some highlights from the latest report:

  • “The conditions necessary to prevent famine have not been met and the latest evidence confirms that famine is imminent in the northern governorates and projected to occur anytime between mid-March and May 2024”
  • 88 per cent of Gazans now face food insecurity levels classified as IPC level four or above, which corresponds to an emergency level or worse
  • Among this population, about 50 per cent (1.1 million people) are in a catastrophe situation, or IPC phase five
  • The level of acute malnutrition is expected to surpass the famine threshold (30 per cent) in northern Gaza, with the steep increase of wasting prevalence, from 0.8 to 15 per cent, over several months
  • The upward trend in non-trauma mortality is also expected to accelerate, resulting in crossing the famine threshold imminently by May 2024 
  • The increased nutritional vulnerability of children, pregnant and breastfeeding women and the elderly is a particular source of concern




  1. What exactly are the main differences in how hunger is tracked now compared to the 1970s and 1980s?

    1. Famines today are tracked through advanced technology and data analysis methods, allowing for quicker and more accurate identification of at-risk populations. In the past, reliance on basic indicators and slower communication channels hindered timely response to hunger crises.

  2. As someone who has been following food security issues closely, I appreciate the detailed explanation provided by WFP’s Mr. Husain. It’s alarming to see the conditions that must be met for a famine to be declared. We must work to prevent such crises and ensure that no one goes hungry or dies from lack of access to food.

  3. It’s crucial to address the triggers of famine before it reaches a critical point. Prevention is key to ensuring that people do not suffer from hunger-related deaths and children do not become malnourished. Collective action is needed to tackle this pressing issue.

  4. What specific actions can governments and international organizations take to prevent famine from occurring in the first place?

    1. Governments and international organizations can take proactive measures to prevent famine by implementing early warning systems, investing in sustainable agriculture and food production, providing humanitarian aid to vulnerable populations, promoting conflict resolution to ensure access to food supplies, and supporting poverty reduction initiatives to enhance food security among the most marginalized communities. It requires a comprehensive approach involving coordinated efforts at local, national, and global levels to address root causes and build resilience to prevent the devastating impact of famine.

  5. In my opinion, it is crucial to have clear thresholds for identifying famine, as outlined by Mr. Husain. The criteria of extreme hunger levels, child wastage, and increased mortality rates serve as critical indicators for taking preventive action against potential famine situations. It’s a collective responsibility to act proactively to prevent the dire consequences of hunger and malnutrition.

  6. As a nutrition specialist, I couldn’t agree more with Mr. Husain’s insights on famine. It’s crucial to intervene early to prevent widespread malnutrition and hunger-related deaths. Collaborative efforts are vital to address the root causes and ensure food security for all.

  7. I believe it’s crucial to act swiftly and effectively to address food insecurity before it escalates to famine. Prevention is key to ensuring that people don’t suffer from hunger and malnutrition-related deaths.

  8. Famines today are different than those experienced in the 1970s or 1980s, when drought was the main driver. It’s heartbreaking to see the conditions that lead to famine, and we must take action to prevent such tragedies from occurring.

  9. As a long-time advocate for food security, I appreciate Mr. Husain’s clear explanation of famine thresholds. It’s indeed crucial to intervene early and prevent such tragedies from happening.

  10. It’s alarming how the conditions for declaring a famine are so severe. We need to address hunger issues long before they escalate to such catastrophic levels. Prevention is key!

  11. As an advocate for food security, I believe it is crucial to emphasize early intervention before a crisis reaches famine levels. Prevention is key to ensuring that no population faces the horrors of widespread malnutrition and hunger-related deaths.

  12. As a mother myself, it breaks my heart to read about famine and hunger crises. We must do more to prevent such devastating situations. It’s a collective responsibility to ensure no child goes to bed hungry or wasted. Let’s act proactively and prevent famine before it’s too late.
