Kwashiorkor is a form of severe protein malnutrition characterized by edema and an enlarged liver with fatty infiltrates. It is thought to be caused by sufficient calorie intake, but with insufficient protein consumption, which distinguishes it from marasmus. Recent studies have found that a lack of antioxidant micronutrients such as β-carotene, lycopene, other carotenoids, and vitamin C as well as the presence of aflatoxins may play a role in the development of the disease. However, the exact cause of kwashiorkor is still unknown. Inadequate food supply is correlated with occurrences of kwashiorkor; occurrences in high income countries are rare. It occurs amongst weaning children to ages of about five years old.
Food security is the state of having reliable access to a sufficient quantity of affordable, nutritious food. The availability of food for people of any class and state, gender or religion is another element of food security. Similarly, household food security is considered to exist when all the members of a family, at all times, have access to enough food for an active, healthy life. Individuals who are food-secure do not live in hunger or fear of starvation. Food security includes resilience to future disruptions of food supply. Such a disruption could occur due to various risk factors such as droughts and floods, shipping disruptions, fuel shortages, economic instability, and wars. Food insecurity is the opposite of food security: a state where there is only limited or uncertain availability of suitable food.
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form.
Marasmus is a form of severe malnutrition characterized by energy deficiency. It can occur in anyone with severe malnutrition but usually occurs in children. Body weight is reduced to less than 62% of the normal (expected) body weight for the age. Marasmus occurrence increases prior to age 1, whereas kwashiorkor occurrence increases after 18 months. It can be distinguished from kwashiorkor in that kwashiorkor is protein deficiency with adequate energy intake whereas marasmus is inadequate energy intake in all forms, including protein. This clear-cut separation of marasmus and kwashiorkor is however not always clinically evident as kwashiorkor is often seen in a context of insufficient caloric intake, and mixed clinical pictures, called marasmic kwashiorkor, are possible. Protein wasting in kwashiorkor generally leads to edema and ascites, while muscular wasting and loss of subcutaneous fat are the main clinical signs of marasmus, which makes the ribs and joints protrude.
Famine scales are metrics of food security going from entire populations with adequate food to full-scale famine. The word "famine" has highly emotive and political connotations and there has been extensive discussion among international relief agencies offering food aid as to its exact definition. For example, in 1998, although a full-scale famine had developed in southern Sudan, a disproportionate amount of donor food resources went to the Kosovo War. This ambiguity about whether or not a famine is occurring, and the lack of commonly agreed upon criteria by which to differentiate food insecurity has prompted renewed interest in offering precise definitions. As different levels of food insecurity demand different types of response, there have been various methods of famine measurement proposed to help agencies determine the appropriate response.
The anthropometry of the upper arm is a set of measurements of the shape of the upper arms.
The Sahrawi refugee camps, also known as the Tindouf camps, are a collection of refugee camps set up in the Tindouf Province, Algeria, in 1975–76 for Sahrawi refugees fleeing from Moroccan forces, who advanced through Western Sahara during the Western Sahara War. With most of the original refugees still living in the camps, the situation is among the most protracted in the world.
Occurring between July 2011 and mid-2012, a severe drought affected the entire East African region. Said to be "the worst in 60 years", the drought caused a severe food crisis across Somalia, Djibouti, Ethiopia and Kenya that threatened the livelihood of 9.5 million people. Many refugees from southern Somalia fled to neighboring Kenya and Ethiopia, where crowded, unsanitary conditions together with severe malnutrition led to a large number of deaths. Other countries in East Africa, including Sudan, South Sudan and parts of Uganda, were also affected by a food crisis.
There were 735.1 million malnourished people in the world in 2022, a decrease of 58.3 million since 2005, despite the fact that the world already produces enough food to feed everyone and could feed more than that.
As of 31 August 2020, Cameroon hosted a total refugee population of approximately 421,700. Of these, 280,500 were from the Central African Republic, driven by war and insecurity. In the Far North Region, Cameroon hosts 114,300 Nigerian refugees, with the population sharing their already scarce resources with the refugees.
Undernutrition in children, occurs when children do not consume enough calories, protein, or micronutrients to maintain good health. It is common globally and may result in both short and long term irreversible adverse health outcomes. Undernutrition is sometimes used synonymously with malnutrition, however, malnutrition could mean both undernutrition or overnutrition. The World Health Organization (WHO) estimates that malnutrition accounts for 54 percent of child mortality worldwide, which is about 1 million children. Another estimate, also by WHO, states that childhood underweight is the cause for about 35% of all deaths of children under the age of five worldwide.
Hospitals and small medical centers and posts are found throughout the island of Madagascar, although they are concentrated in urban areas and particularly in Antananarivo. In addition to the high expense of medical care relative to the average Malagasy income, the prevalence of trained medical professionals remains extremely low.
Since 2016, a food insecurity crisis has been ongoing in Yemen which began during the Yemeni civil war. The UN estimates that the war has caused an estimated 130,000 deaths from indirect causes which include lack of food, health services, and infrastructure as of December 2020. In 2018, Save the Children estimated that 85,000 children have died due to starvation in the three years prior. In May 2020, UNICEF described Yemen as "the largest humanitarian crisis in the world", and estimated that 80% of the population, over 24 million people, were in need of humanitarian assistance. In September 2022, the World Food Programme estimated that 17.4 million Yemenis struggled with food insecurity, and projected that number would increase to 19 million by the end of the year, describing this level of hunger as "unprecedented." The crisis is being compounded by an outbreak of cholera, which resulted in over 3000 deaths between 2015 and mid 2017. While the country is in crisis and multiple regions have been classified as being in IPC Phase 4, an actual classification of famine conditions was averted in 2018 and again in early 2019 due to international relief efforts. In January 2021, two out of 33 regions were classified as IPC 4 while 26 were classified as IPC 3.
In the early months of 2017, parts of South Sudan experienced a famine following several years of instability in the country's food supply caused by war and drought. The famine, largely focused in the northern part of the country, affected an estimated five million people. In May 2017, the famine was officially declared to have weakened to a state of severe food insecurity.
Rohingya refugees in Bangladesh mostly refer to forcibly displaced Myanmar nationals from Myanmar who are living in Bangladesh. The Rohingya people have experienced ethnic and religious persecution in Myanmar for decades. Hundreds of thousands have fled to other countries in Southeast Asia, including Malaysia, Indonesia, and Philippines. The majority have escaped to Bangladesh, where there are two official, registered refugee camps. Recently violence in Myanmar has escalated, so the number of refugees in Bangladesh has increased rapidly. According to the UN Refugee Agency (UNHCR), more than 723,000 Rohingya have fled to Bangladesh since 25 August 2017.
Hunger in Bangladesh is one of the major issues that affects the citizens of Bangladesh. The nation state of Bangladesh is one of the most densely populated countries in the world and home for more than 160 million people. It progresses immensely in the Human Development Index, particularly in the areas of literacy and life expectancy, but economic inequality has increased and about 32% of the population, that is 50 million people, still live in extreme poverty.
Sustainable Development Goal 2 aims to achieve "zero hunger". It is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording is: "End hunger, achieve food security and improved nutrition and promote sustainable agriculture". SDG 2 highlights the "complex inter-linkages between food security, nutrition, rural transformation and sustainable agriculture". According to the United Nations, there were up to 757 million people facing hunger in 2023 – one out of 11 people in the world, which accounts for slightly less than 10 percent of the world population. One in every nine people goes to bed hungry each night, including 20 million people currently at risk of famine in South Sudan, Somalia, Yemen and Nigeria.
In mid-2021, a severe drought in southern Madagascar caused hundreds of thousands of people, with some estimating more than 1 million people including nearly 460,000 children, to suffer from food insecurity or Kere (famine). Some organizations have attributed the situation to the impact of climate change and the handling of the COVID-19 pandemic in the country.
Throughout 2024, the population of Sudan suffered from severe malnutrition and human-made famine conditions as a result of the Sudanese civil war beginning in 2023, primarily in Darfur, Kordofan, and neighboring refugee-taking nations such as Chad. Famine conditions were caused in part by deliberate attempts by the Rapid Support Forces (RSF) to siege and loot cities with civilians trapped in them and by both sides blocking off supply routes to allow food and humanitarian aid to flow through. On 1 August, the Global Famine Review Committee released a report officially declaring that there was a high risk of IPC Phase 5 famine conditions ongoing throughout internally displaced persons (IDP) camps in Darfur near Al-Fashir. More than 1,050 deaths have been caused by the famine and over 9 million people have been displaced as a result of the famine and war.
The Zamzam refugee camp is one of the largest internally displaced persons (IDP) camps in Sudan, located 15 kilometres (9.3 mi) south of Al-Fashir, North Darfur. It was established in 2004 to accommodate the massive influx of people displaced by the war in Darfur. As of now, the camp houses approximately 500,000 displaced individuals. In the light of the Sudanese civil war (2023–present), the camp is currently facing severe humanitarian challenges, including a catastrophic malnutrition crisis. Conditions have deteriorated to the point where famine-like situations have emerged, with reports of high child mortality rates, and experts describe the crisis as man-made and preventable.
