Keywords: Hunger: chronic undernourishment or outright starvation leading to death. Chronic Hunger: long-term lack or shortage of food Periodic Hunger: short-term hunger, caused by factors such as war, natural disasters, etc. Malnutrition: a diet that is lacking (or having too much) in quality and quantity of food. Starvation: limited or non-existence of food Famine: Long-term and severe food shortage or unavailability of food in a given area. Undernourishment: the share of the population that is under-nourished (that is, whose caloric intake is insufficient); Child wasting: the share of children under the age of five who are wasted (that is, who have low weight for their height, reflecting acute undernutrition); Child stunting: the share of children under the age of five who are stunted (that is, who have low height for their age, reflecting chronic undernutrition); and Child mortality: the mortality rate of children under the age of five (in part, a reflection of the fatal mix of inadequate nutrition and unhealthy environments). Food security for a population exists when all its people, at all times, have access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life. HALE: Health-adjusted life expectancy- the length of time that an individual can expect to live based on adjustments made for years of ill health. The Global Hunger Index (GHI): ranks countries on a 100-point scale, with O being the best score (no hunger) and 100 being the worst. Based on child wasting, child stunting, child mortality, undernourishment and child mortality. Calorie intake: is the amount of food (measured in calories) a person consumes. Undernutrition: Inadequate consumption, poor absorption or excessive loss of nutrients Overnutrition: overindulgence or excessive intake of specific nutrients Malnutrition: refers to both undernutrition and overnutrition Temporary hunger: insufficient food supply for a short period of time leading to discomfort Chronic hunger: insufficient food supply for a long period of time Famine: an acute but prolonged shortage of food that is life-threatening Disease of Poverty: Disease that people in LICs die from Disease of influence: Disease that people in HICs die from (tends to be degenerative) Communicable: Disease that can spread from person to person (Common to die from in LIC) Non-Communicable: Disease that cannot spread from person to person (Cancer) Vector Borne Disease: refers to illnesses that are transmitted to humans or animals through the bite of infected arthropods, commonly known as vectors. Endemic: refers to the constant presence or usual prevalence of a disease or infectious agent within a specific geographic area or population. Global patterns in food and nutrition indicators: Facts/Statistics: ● Since 2000, Rwanda, Angola, and Ethiopia have experienced the biggest absolute reductions in hunger, with GHI scores down by between 25 and 28 points in each country. ● The combination of high rates of hunger and only a small reduction in the GHI score since 2000 for the Central African Republic, Chad, and Zambia is a cause for concern. Calorie Intake Stats: ● In general, high-income countries have an intake of around 3,400 kcal/person/day. In contrast, people in low-income countries intake around 2,600 kcal/person/day. However, in sub-Saharan ● In Africa, the intake is down to 2,240 kcal/person/day ● In Central Africa, it is just 1,820 kcal/person/day. ● In Burundi and Eritrea, daily calorie intakes are as low as 1,680 and 1,590 kcal, respectively. Indicators of malnutrition: Types of malnutrition: ● ● ● ● ● ● Deficiency diseases such as pellagra result from a lack of specific vitamins or minerals. Kwashiorkor is a lack of protein in the diet. Marasmus is a lack of calories/energy. Obesity results from eating too many energy/protein foods. Starvation refers to a limited or non-existent intake of food. Temporary hunger is a short-term decline in the availability of food to a population in an area. ● Famine occurs when there is a long-term decline in the availability of food in a region. Hunger: ● A healthy brain uses 20% of the body's energy and that energy comes from food. ● When a child is hungry the brain is starved and malnourished kids fall behind in school because they can't concentrate. ● A healthy heart pumps a steady supply of blood throughout the body, but the heart of a hungry child shrinks, literally so it has to work extra hard to pump enough blood. ● Healthy bones get bigger and stronger as a child grows but when a child is malnourished, their skin cracks allowing infections to get in. ● Their bones stop growing, which is why hungry kids often end up being small for their age (child stunting) The nutrition transition: ● As a country’s GDP per capita increases the calories the average person’s daily calories increase. HALE: ● It is an indicator of the overall health of a population. ● It combines measures of both age- and sex-specific health data, and age- and sex-specific mortality data, into a single statistic. ● HALE indicates the number of expected years of life equivalent to years lived in full health, based on the average experience in a population. ● Thus, HALE is a measure not only of quantity of life but of quality of life. Epidemiological Transition Model: ● One of the main changes in a country's health profile is the shift from infectious or contagious communicable diseases (epidemics) to non-communicable diseases that cause a gradual worsening in the health of an individual (degenerative diseases). ● For example, a country in an early stage of development would be expected to have a large number of deaths and illnesses from infectious diseases. ● By contrast, we would expect an HIC to have more deaths and illnesses from heart attack, stroke and cancers - diseases that are not infectious or communicable. ● We've seen an increase in life expectancy with this an increase in the diseases that are prevalent among the elderly ● Non-communicable diseases today kill 40 million people every year. That's about 70% of all deaths globally. ● 15 million of these people are relatively young, between the ages of 30 and 69. And, ● 80% of these premature deaths, many of which are preventable, occur in low and middle-income countries.

Media has influenced diets, what is considered healthy and unhealthy ● The promotion of convenience foods, such as ready-to-eat meals, has altered traditional cooking and eating practices. These trends are more evident in urban areas, where fast-paced lifestyles favour convenience over traditional food preparation. ● The global spread of similar food products and brands leads to a reduction in culinary diversity. ● Local food cultures and traditional cuisines are increasingly overshadowed by global food trends propagated by TNCs. ● The proliferation of processed and fast foods, heavily marketed by TNCs, has led to nutritional challenges. These foods are often high in calories, fats, sugars, and salt, contributing to health issues like obesity, heart disease, and diabetes. ● There has been a notable shift towards Western dietary patterns around the world, characterized by increased consumption of meat, dairy products, and processed foods. ● TNCs' influence can affect the affordability and accessibility of healthy, nutritious food options, particularly in lower-income communities and developing countries. ● Through branding and advertising, TNCs create and reinforce perceptions about food products, often prioritizing processed and fast foods. ● The advent of digital media has expanded the reach and sophistication of food marketing. Online platforms enable targeted advertising, influencing specific demographics, particularly younger audiences.

Said to be the worst in 60 years Amartya Sen- Nobel Peace Prize winner: “FAMINE HAPPENS IN THE PRESENCE OF FOOD” In 2022- Aid was paused from the USA as Ethiopian officials have been stealing food aid 1 in 7 people wake up not knowing what they will eat during the day Every 10 seconds a child dies due to hunger Up to 40% less brain volume in malnourished children- earning potential for these children is cut in half A child could be saved every 22 seconds if there was breastfeeding in the first 6 months of their life- in Niger however one of the world lowest income countries, only 7% of babies are breastfed due to the Western push of baby formula- especially Nestle ● Theory: Core Peripacy- Those that have and those that don’t Females and Food Security: ● Women and girls make up 60 percent of the world's chronically hungry. ● Women face discrimination both in education and employment opportunities and within households, where their bargaining power is lower than men's. ● Women also face discrimination in access to land, training, technologies, finance and other services. ● Achieving gender equality is instrumental in ending malnutrition as women tend to be responsible for food preparation and childcare within the family and are more likely to spend their income on food and their children's needs. ● Research has shown that a child's chances of survival increase by 20 percent when the mother controls the household budget. ● Studies suggest that if women had the same access to productive resources as men, they would increase yields by 20 to 30 percent raising overall agricultural production in developing countries by 2.5 to 4 percent. ● Studies from Africa show that children of mothers who have spent five years in education are 40 per cent more likely to live beyond the age of 5. ● Access to most financial services such as credit and insurance is only available to men in rural areas. This greatly limits food security and farming innovation for women. Possible solutions to food insecurity: HICs have successfully implemented policies (such as the Common Agriculture Policies in the EU) to achieve sustainability in food production, but ensuring food security still remains a big challenge in most LICs. a) Economic solution ● Investment in agriculture – financial investment such as agriculture subsidies given by the government could be given to farmers in order to increase food production. b) Political solution Food Aid: ● ● ● Food aid helps to alleviate food shortages because they serve as an emergency source of food during war or natural disasters like famine or drought. eg. food aid was sent to Nepal when the country was affected by an earthquake. Food aid also reduces the financial pressure on the government. However, food aid can damage the local production of food in the recipient country. For example in 2002-2003, food aid donors overreacted to a projected 600,000 metric tonne deficit in Malawi causing a severe decline in cereal prices and hurting local producers. Fair trade: ● Fairtrade attempts to be socially, economically and environmentally responsible. ie. They adopt policies that meet the livelihood of the people, respect/preserve their local culture and protect/use environmental resources wisely. Free trade: ● An agreement between two countries to trade between themselves without any restrictions or barriers. Examples of free trade include ACP, NAFTA (North Atlantic Free Trade Area), the EU, ECOWAS (Economic Community of West African States) ● Trade with other countries could potentially lead to increased production of food crops for export, thereby making money available for the farmer to invest in agriculture on a large scale. This will also ensure regular income for the farmer and encourage them to stay in agriculture. ● Free trade makes food cheaper for the recipient country because there are no tariffs imposed on imported food Vitro Meat: USE UR COMMON SENSE GMO: Disadvantages: ● Releasing GMOs into the natural environment can damage natural varieties that are cultivated, which could alter the genetic makeup of foods consumed by humans. ● It may lead to the growth of superweeds, meaning weeds that have become resistant to herbicides ● GM seeds come with a lot of issues, such as patent rights etc which means that farmers cultivating GM crops are not allowed to store the seeds for another growing season without the permission of the engineering company. ● The cultivation of GM foods could make disease-causing bacteria that are resistant to antibiotics Advantages: ● GMOs have the ability to withstand powerful herbicides. ● GMOs have also been developed to improve the nutrient content of food. For example, some varieties of rice have high levels of Vitamin A, higher than organic rice, which is beneficial for consumers in low-income countries ● GMOs are also said to be insect-resistant. This means they are able to resist pest infestation, as certain toxic bacteria are sometimes added to the GM crop in order to reduce the number of insecticides needed. ● GMOs are developed to resist drought and extreme temperatures, in some circumstances. This means that farmers in areas experiencing water shortages or low rainfall can cultivate GM crops without having to worry about sufficient rainfall. Vertical farming- growing crops in layers: USE UR COMMON SENSE Diabetes Pandemic Case Study: ● The number of people worldwide with diabetes is around 422 million, a figure likely to double in the next 20 years. ● Diabetes is a chronic, lifelong condition and a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation. ● The disease reduces both a person's quality of life and life expectancy. ● In 2012 1.5 million people died as a result of having the disease. The death rate of men with diabetes is 1.9 times the rate for men without diabetes, and the rate for women with diabetes is 2.6 times that for women without diabetes. Three types of diabetes: ● Type I occurs when the pancreas produces insufficient insulin. It requires daily administration of insulin by injection. The cause is unknown but it may be genetic. ● Type II, the most common type, is non-insulin-dependent and results from the body's ineffective use of insulin. ● Type Ill is found in some women who become diabetic during pregnancy; their children are at increased risk of developing type Il in early adulthood. ● If diabetes is not well managed, over time this can damage blood vessels and may lead to the conditions, reducing the quality of life and causing permanent disability. ● Hypoglycemia is low blood sugar the opposite of hyperglycemia - and symptoms include sweating, tremors and confusion. Treatment: ● ● ● ● ● ● blood sugar control, blood pressure control, foot care and preconception care for women. More sophisticated types of care, found in HICs where funding is greater, include the drug metformin for those needing to boost their own insulin supply annual eye examinations and cholesterol control. insulin can be supplied to those requiring it. sophisticated treatments are ineffective without lifestyle changes and good self-management of the condition. Daily blood testing is an essential requirement. Risk factors for diabetes (causes): ● Obesity - The strongest and most consistent risk factors for diabetes and insulin resistance among different populations are obesity and weight gain: for each unit increase in body mass index, the risk of diabetes increases by 12 percent. ● Physical inactivity - A sedentary lifestyle and physical inactivity are also associated with increased risks of developing diabetes. ● Diet - Saturated fats and trans fatty acids may increase the risk of diabetes, as may sugar-sweetened beverages. Conversely, high intakes of dietary fibre and of vegetables may reduce the risk. ● Increased affluence - The adoption of western lifestyles has been associated with an increase in the prevalence of diabetes in many indigenous populations. The economic burden of diabetes: ● ● ● ● Diabetes imposes large economic burdens on national healthcare systems and affects national economies, families and individuals. Direct medical costs include resources used to treat the disease. Indirect costs include lost productivity caused by morbidity, disability and premature mortality. Intangible costs are the reduced quality of life for people with diabetes HIV AIDS Eswatini Pandemic Case Study: Causes Consequences (SEE) Responses (L,N,I) Sexual transmission is more common from man to woman- (sex work in LIC) (stigma against gay people is wrong) Social: Low status of women to say no to unprotected sex -Death of parents left the burden on grandparents and orphanages National: A community-led organization called Swaziland AIDS Support Organization (SASO) as a support group for people living with HIV.

Indirect inputs refer to pesticides, irrigation, electricity, transport etc. A subsistence farmer relying on mainly intensive labor inputs is likely to have low energy input. However, the energy efficiency of the system will depend on the quantity of food produced. If only a small amount of food is produced the energy efficiency is likely to be poor. Likewise, a large intensive farm in Canada with a huge variety of direct and indirect energy inputs might achieve an efficient energy ratio provided it produces an abundance of food. EER = Energy Outputs/Energy Inputs- A ratio equal to or above 1 is considered an efficient ratio ● If the energy efficiency is positive (i.e. energy efficiency is above 1), one may consider roughly that more CO2 has been captured than spent in the farming process: in that case, agriculture is effectively a sink of carbon dioxide, even though it is a short-term sink. ● Energy efficiency on its own as an indicator is useful for looking at the overall efficiency of energy use within a farming system and it's particularly relevant in the context of climate change and the vital importance of achieving energy efficiency. Negatives: ● ● ● Narrow focus as an indicator of environmental impact is its. Neglects to examine the wider environmental impacts of the farming system such as soil quality, water resources, and long-term conditions of the natural environment. Doesn't take into account the social measurements relating to society and farmer well-being which are important to the broader interpretation of sustainable agriculture definitions. It therefore doesn't address the wider sustainability issues of agriculture. Attempt to Tackle Food Insecurity Case Study in Timor-Leste : EU Case Study Maternal and Child Nutrition: Context: ● Poverty, food insecurity and undernutrition remain widespread in Timor-Leste (a Southeast Asian nation). ● According to the recently compiled Timor-Leste Food and Nutrition Survey (2013), a reduction of stunting from 58% to 50.2% and wasting from 19% to 11% have been recorded. ● That still leaves approximately 50% of Timorese under-five children (or almost 100 000 children) still stunted according to the UNICEF/Ministry of Health survey. Objectives: ● The project goal is to reduce child and maternal undernutrition in Timor-Leste by supporting the implementation of Mother and Child Health and Nutrition – Targeted Supplementary Feeding Program in six priority districts ● To strengthen Ministry of Health capacity to reduce under nutrition through the Mother and Child Health and Nutrition-Targeted Supplementary Feeding Programme. ● To improve the nutritional status (reduce under nutrition) of targeted women and children and to increase the coverage rate of the Targeted Supplementary Feeding Programme. Results: ● 78 health care service points in all six districts assessed for 'Health Facility readiness' for the TSFP programme. ● More than 200 Ministry of Health staff at District and sub-district levels have been trained on the TSFP ● More than 300 community members including village elders, and district authorities have been oriented on the TSFP during “socialization sessions” in the target district. ● 100% of deliveries to the Sub-district level and 90% + of deliveries to the Health Facility level of the RUSF have been completed in the 3 initial districts. ● 866 children with Moderate Acute Malnutrition were treated with RUSF during the 1st month’s implementation
