144-416: A famine is a widespread scarcity of food caused by several possible factors, including, but not limited to war , natural disasters , crop failure , widespread poverty , an economic catastrophe or government policies . This phenomenon is usually accompanied or followed by regional malnutrition , starvation , epidemic , and increased mortality . Every inhabited continent in the world has experienced
288-590: A drying oil in painting and varnishing. Although brown flax seed varieties may be consumed as readily as the yellow ones, and have been for thousands of years, these varieties are more commonly used in paints, for fiber, and for cattle feed. A 100-gram portion of ground flax seed supplies about 2,234 kilojoules (534 kilocalories) of food energy , 41 g of fat, 28 g of fiber, and 20 g of protein. Whole flax seeds are chemically stable, but ground flax seed meal, because of oxidation , may go rancid when left exposed to air at room temperature in as little as
432-465: A gravelly or dry sandy nature. Farming flax requires few fertilizers or pesticides . Within eight weeks of sowing, the plant can reach 10–15 cm (3.9–5.9 in) in height, reaching 70–80 cm (28–31 in) within 50 days. In 2022, world production of raw or retted flax was 875,995 tonnes , led by France with 75% of the total. One of the largest regions in France for flax production
576-504: A nutritional supplement and as an ingredient in many wood-finishing products. Flax is also grown as an ornamental plant in gardens. Moreover, flax fibers are used to make linen . The specific epithet in its binomial name, usitatissimum, means "most useful". Flax fibers taken from the stem of the plant are two to three times as strong as cotton fibers. Additionally, flax fibers are naturally smooth and straight. Europe and North America both depended on flax for plant-based cloth until
720-449: A pigment binder in oil paints , as a plasticizer and hardener in putty , and in the manufacture of linoleum . Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing. Flax seed and its oil are generally recognized as safe for human consumption. Like many common foods, flax contains small amounts of cyanogenic glycoside , which
864-756: A textile comes from the present-day Republic of Georgia , where spun, dyed, and knotted wild flax fibers found in Dzudzuana Cave date to the Upper Paleolithic , 30,000 years ago. Humans first domesticated flax in the Fertile Crescent region. Evidence exists of a domesticated oilseed flax with increased seed-size from Tell Ramad in Syria and flax fabric fragments from Çatalhöyük in Turkey by c. 9,000 years ago. Use of
1008-485: A BMI greater than 27. Another meta-analysis showed that consumption of flax seeds for more than 12 weeks produced small reductions in systolic blood pressure and diastolic blood pressure . A third showed that consuming flax seed or its derivatives may reduce total and LDL-cholesterol in the blood, with greater benefits in women and people with high cholesterol . A fourth showed a small reduction in c-reactive protein (a marker of inflammation) only in persons with
1152-605: A backdrop of conventional interventions through the state or markets, alternative initiatives have been pioneered to address the problem of food security. One pan-African example is the Great Green Wall . Another example is the "Community Area-Based Development Approach" to agricultural development ("CABDA"), an NGO programme with the objective of providing an alternative approach to increasing food security in Africa. CABDA proceeds through specific areas of intervention such as
1296-510: A body mass index greater than 30. Linseed oil , also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant ( Linum usitatissimum ). The oil is obtained by pressing , sometimes followed by solvent extraction . Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing , as
1440-405: A combine then harvests the seeds similar to wheat or oat harvesting. The plant is pulled up with the roots (not cut), so as to increase the fiber length. After this, the flax is allowed to dry, the seeds are removed, and it is then retted . Dependent upon climatic conditions, characteristics of the sown flax and fields, the flax remains on the ground between two weeks and two months for retting. As
1584-743: A diverse range of species from annelids to elephants, chimpanzees and many birds. About 182 fish consume seeds or fruit. Animals (domesticated and wild) use as many types of grasses that have adapted to different locations as their main source of nutrients. Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms , of which perhaps 7,000 are often eaten. Plants can be processed into breads, pasta, cereals, juices and jams or raw ingredients such as sugar, herbs, spices and oils can be extracted. Oilseeds are pressed to produce rich oils – sunflower , flaxseed , rapeseed (including canola oil ) and sesame . Many plants and animals have coevolved in such

#17327659085521728-739: A famine carries no binding obligations on the UN or member states, but serves to focus global attention on the problem. The scarcity of food refers to a situation where the availability of food is insufficient to meet the demands of a population, often resulting from factors like poor agricultural productivity, climate change, political instability, or economic crises. This shortage can lead to widespread hunger, malnutrition, and social unrest, especially in vulnerable regions. Food scarcity affects not only individual health and well-being but also contributes to greater inequality and economic decline as prices for essential items rise dramatically, further limiting access for
1872-473: A famine created by human rights abuses is the 1998 Sudan famine . AIDS is also having long-term economic effects on agriculture by reducing the available workforce, and is creating new vulnerabilities to famine by overburdening poor households. On the other hand, in the modern history of Africa on quite a few occasions famines acted as a major source of acute political instability. In Africa, if current trends of population growth and soil degradation continue,
2016-513: A famine of the proportions of the Great Leap Forward since 1961. Japan experienced more than 130 famines between 1603 and 1868. Food Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates , fats , proteins , vitamins , or minerals . The substance is ingested by an organism and assimilated by
2160-765: A further disadvantage, because this fatty acid oxidises and goes rancid quickly, which shortens the storage time. Linola was developed in Australia and introduced in the 1990s with less omega-3, specifically to serve as fodder . Another disadvantage of the meal and seed is that it contains a vitamin B6 ( pyridoxine ) antagonist, and may require this vitamin be supplemented, especially in chickens , and furthermore linseeds contain 2–7% of mucilage (fibre), which may be beneficial in humans and cattle, but cannot be digested by non-ruminants and can be detrimental to young animals, unless possibly treated with enzymes . Linseed meal
2304-583: A high protein, fibre, vitamin E and B content. Seeds are a good source of food for animals because they are abundant and contain fibre and healthful fats, such as omega-3 fats . Complicated chemical interactions can enhance or depress bioavailability of certain nutrients. Phytates can prevent the release of some sugars and vitamins. Animals that only eat plants are called herbivores , with those that mostly just eat fruits known as frugivores , leaves, while shoot eaters are folivores (pandas) and wood eaters termed xylophages (termites). Frugivores include
2448-678: A million. Herbivores generally have more than carnivores as they need to tell which plants may be poisonous. Not all mammals share the same tastes: some rodents can taste starch , cats cannot taste sweetness, and several carnivores (including hyenas , dolphins, and sea lions) have lost the ability to sense up to four of the five taste modalities found in humans. Food is broken into nutrient components through digestive process. Proper digestion consists of mechanical processes ( chewing , peristalsis ) and chemical processes ( digestive enzymes and microorganisms ). The digestive systems of herbivores and carnivores are very different as plant matter
2592-403: A network of granaries . Its famines generally occurred immediately after El Niño-Southern Oscillation -linked droughts and floods. These events are comparable, though somewhat smaller in scale, to the ecological trigger events of China's vast 19th-century famines. Qing China carried out its relief efforts, which included vast shipments of food, a requirement that the rich open their storehouses to
2736-551: A percentage of total fat , flax seeds contain 54% omega-3 fatty acids (mostly ALA ), 18% omega-9 fatty acids ( oleic acid ), and 6% omega-6 fatty acids ( linoleic acid ); the seeds contain 9% saturated fat , including 5% as palmitic acid . Flax seed oil contains 53% 18:3 omega-3 fatty acids (mostly ALA) and 13% 18:2 omega-6 fatty acids. A meta-analysis showed that consumption of more than 30 g of flax-seed daily for more than 12 weeks reduced body weight, body mass index (BMI), and waist circumference for persons with
2880-406: A period of famine throughout history. During the 19th and 20th century, Southeast and South Asia , as well as Eastern and Central Europe , suffered the greatest number of fatalities due to famine. Deaths caused by famine declined sharply beginning in the 1970s, with numbers falling further since 2000. Since 2010, Africa has been the most affected continent in the world by famine. According to
3024-401: A result of alternating rain and the sun, an enzymatic action degrades the pectins which bind fibers to the straw. The farmers turn over the straw during retting to evenly rett the stalks. When the straw is retted and sufficiently dry, it is rolled up. It is then stored by farmers before extracting the fibers. Threshing is the process of removing the seeds from the rest of the plant. Separating
SECTION 20
#17327659085523168-508: A series of government guidelines and regulations on how to respond to famines and food shortages called the Famine Code. The famine code was also one of the first attempts to scientifically predict famine in order to mitigate its effects. These were finally passed into law in 1883 under Lord Ripon . The Code introduced the first famine scale : three levels of food insecurity were defined: near-scarcity, scarcity, and famine. "Scarcity"
3312-415: A similar oil profile to brown flax seeds and both are very high in omega-3s ( alpha-linolenic acid (ALA), specifically). Flax seeds produce a vegetable oil known as flax seed oil or linseed oil , which is one of the oldest commercial oils. It is an edible oil obtained by expeller pressing and sometimes followed by solvent extraction . Solvent-processed flax seed oil has been used for many centuries as
3456-546: A source of food for protozoa, who in turn provide a source of food for other organisms such as small invertebrates. Other organisms that feed on bacteria include nematodes, fan worms, shellfish and a species of snail. In the marine environment, plankton (which includes bacteria , archaea , algae , protozoa and microscopic fungi ) provide a crucial source of food to many small and large aquatic organisms. Without bacteria, life would scarcely exist because bacteria convert atmospheric nitrogen into nutritious ammonia . Ammonia
3600-510: A strategy of generating employment for these sections of the population and relied on open-ended public works to do so. During the 20th century, an estimated 70 to 120 million people died from famines across the world , of whom over half died in China, with an estimated 30 million dying during the famine of 1958–1961 , up to 10 million in the Chinese famine of 1928–1930 , and over two million in
3744-568: A substitute for tallow in increasing marbling . In the US, flax-based feed for ruminants is often somewhat more expensive than other feeds on a nutrient basis. Sheep feeding on low quality forage are able to eat a large amount of linseed meal, up to 40% in one test, with positive consequences. It has been fed as supplement to water buffaloes in India, and provided a better diet than forage alone, but not as good as when substituted with soy meal. It
3888-425: A system with nineteen food classifications: cereals, roots, pulses and nuts, milk, eggs, fish and shellfish, meat, insects, vegetables, fruits, fats and oils, sweets and sugars, spices and condiments, beverages, foods for nutritional uses, food additives, composite dishes and savoury snacks. In a given ecosystem, food forms a web of interlocking chains with primary producers at the bottom and apex predators at
4032-456: A way that the fruit is a good source of nutrition to the animal who then excretes the seeds some distance away, allowing greater dispersal. Even seed predation can be mutually beneficial, as some seeds can survive the digestion process. Insects are major eaters of seeds, with ants being the only real seed dispersers. Birds, although being major dispersers, only rarely eat seeds as a source of food and can be identified by their thick beak that
4176-479: A week. Refrigeration and storage in sealed containers will keep ground flax seed meal for a longer period before it turns rancid. Under conditions similar to those found in commercial bakeries, trained sensory panelists could not detect differences between bread made with freshly ground flax seed and bread made with flax seed that had been milled four months earlier and stored at room temperature. If packed immediately without exposure to air and light, milled flax seed
4320-681: A wide range of other social and political issues, including sustainability , biological diversity , economics , population growth , water supply , and food security . Food safety and security are monitored by international agencies like the International Association for Food Protection , the World Resources Institute , the World Food Programme , the Food and Agriculture Organization , and
4464-485: A worldwide problem with hundreds of millions of people suffering. These famines cause widespread malnutrition and impoverishment. The famine in Ethiopia in the 1980s had an immense death toll, although Asian famines of the 20th century have also produced extensive death tolls. Modern African famines are characterized by widespread destitution and malnutrition, with heightened mortality confined to young children. Against

4608-418: Is Normandy with nearly one-third of the world's production. Flax is harvested for fiber production after about 100 days, or a month after the plants flower and two weeks after the seed capsules form. The bases of the plants begin to turn yellow. If the plants are still green, the seed will not be useful, and the fiber will be underdeveloped. The fiber degrades once the plants turn brown. Flax grown for seed
4752-629: Is 9.5 to 13 million people. The largest famine of the 20th century was the 1958–1961 famine associated with the Great Leap Forward in China. The immediate causes of this famine lay in Mao Zedong's ill-fated attempt to transform China from an agricultural nation to an industrial power in one huge leap. Communist Party cadres across China insisted that peasants abandon their farms for collective farms, and begin to produce steel in small foundries, often melting down their farm instruments in
4896-482: Is a flowering plant , Linum usitatissimum , in the family Linaceae . It is cultivated as a food and fiber crop in regions of the world with temperate climates . In 2022, France produced 75% of the world's supply of flax. Textiles made from flax are known in English as linen , and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil . In addition to referring to
5040-401: Is a protein -rich feed for ruminants , rabbits , and fish. It is also often used as feed for swine and poultry , and has also been used in horse concentrate and dog food . The high omega-3 fatty acid ( ALA ) content of linseed meal "softens" milk, eggs, and meat, which means it causes a higher unsaturated fat content and thus lowers its storage time. The high omega-3 content also has
5184-447: Is a fruit if the part eaten is derived from the reproductive tissue , so seeds, nuts and grains are technically fruit. From a culinary perspective, fruits are generally considered the remains of botanically described fruits after grains, nuts, seeds and fruits used as vegetables are removed. Grains can be defined as seeds that humans eat or harvest, with cereal grains (oats, wheat, rice, corn, barley, rye, sorghum and millet) belonging to
5328-696: Is a sensation considered unpleasant characterised by having a sharp, pungent taste. Unsweetened dark chocolate, caffeine , lemon rind, and some types of fruit are known to be bitter. Umami, commonly described as savory, is a marker of proteins and characteristic of broths and cooked meats. Foods that have a strong umami flavor include cheese, meat and mushrooms. While most animals taste buds are located in their mouth, some insects taste receptors are located on their legs and some fish have taste buds along their entire body. Dogs, cats and birds have relatively few taste buds (chickens have about 30), adult humans have between 2000 and 4000, while catfish can have more than
5472-542: Is added to cattle feed as a protein supplement . It can only be added at low percentages due to the high fat content, which is unhealthy for ruminants. Compared to oilseed meal from crucifers it measures as having lower nutrient values, however, good results are obtained in cattle, perhaps due to the mucilage, which may aid in slowing digestion and thus allowing more time to absorb nutrients. One study found that feeding flax seeds may increase omega-3 content in beef , while another found no differences. It might also act as
5616-416: Is allowed to mature until the seed capsules are yellow and just starting to split; it is then harvested in various ways. A combine harvester may either cut only the heads of the plants, or the whole plant. These are then dried to extract the seed. The amount of weeds in the straw affects its marketability, and this, coupled with market prices, determines whether the farmer chooses to harvest the flax straw. If
5760-554: Is an annual plant . Cultivated flax plants grow to 1.2 m (3 ft 11 in) tall, with slender stems. The leaves are glaucous green, slender lanceolate , 20–40 mm long, and 3 mm broad. The flowers are 15–25 mm in diameter with five petals, which can be colored white, blue, yellow, and red depending on the species. The fruit is a round, dry capsule 5–9 mm in diameter, containing several glossy brown seeds shaped like apple pips, 4–7 mm long. The earliest evidence of humans using wild flax as

An account from the First Intermediate Period states, "All of Upper Egypt was dying of hunger and people were eating their children." As for recorded examples about more recent centuries: in the 1680s, famine extended across the entire Sahel , and in 1738 half the population of Timbuktu died of famine. In Egypt , between 1687 and 1731, there were six famines. The famine that afflicted Egypt in 1784 cost it roughly one-sixth of its population. The Maghreb experienced famine and plague in

6048-402: Is caused by acids , such as vinegar in alcoholic beverages. Sour foods include citrus, specifically lemons and limes . Sour is evolutionarily significant as it can signal a food that may have gone rancid due to bacteria. Saltiness is the taste of alkali metal ions such as sodium and potassium. It is found in almost every food in low to moderate proportions to enhance flavor. Bitter taste
6192-474: Is considered an inferior protein supplement for swine because of its fibre, the vitamin antagonist, the high omega-3 content and its low lysine content, and can only be used in small amounts in the feed. Although it may increase the omega-3 content in eggs and meat, it is also an inferior and potentially toxic feed for poultry, although it can be used in small amounts. The meal is an adequate and traditional source of protein for rabbits at 8–10%. Its use in fish feeds
6336-731: Is drunk or processed into dairy products (cheese, butter, etc.). Eggs laid by birds and other animals are eaten and bees produce honey , a reduced nectar from flowers that is used as a popular sweetener in many cultures. Some cultures consume blood , such as in blood sausage , as a thickener for sauces, or in a cured , salted form for times of food scarcity, and others use blood in stews such as jugged hare . Animals, specifically humans, typically have five different types of tastes: sweet , sour , salty , bitter , and umami . The differing tastes are important for distinguishing between foods that are nutritionally beneficial and those which may contain harmful toxins. As animals have evolved ,
6480-477: Is easily over-retted, damaging the fiber. This form of retting also produces quite an odor. Stream retting is similar to pool retting, but the flax is submerged in bundles in a stream or river. This generally takes two or three weeks longer than pond retting, but the end product is less likely to be dirty, does not smell as bad, and because the water is cooler, is less likely to be over-retted. Both pond and stream retting were traditionally used less because they pollute
6624-550: Is extracted from the bast beneath the surface of the stem of the flax plant. Flax fiber is soft, lustrous, and flexible; bundles of fiber have the appearance of blonde hair, hence the description "flaxen" hair. It is stronger than cotton fiber, but less elastic. The use of flax fibers dates back tens of millennia; linen , a refined textile made from flax fibers, was worn widely by Sumerian priests more than 4,000 years ago. Industrial-scale flax fiber processing existed in antiquity. A Bronze Age factory dedicated to flax processing
6768-874: Is found in many foods and has been defined as a food by itself. Water and fiber have low energy densities, or calories , while fat is the most energy-dense component. Some inorganic (non-food) elements are also essential for plant and animal functioning. Human food can be classified in various ways, either by related content or by how it is processed. The number and composition of food groups can vary. Most systems include four basic groups that describe their origin and relative nutritional function: Vegetables and Fruit, Cereals and Bread, Dairy, and Meat. Studies that look into diet quality group food into whole grains/cereals, refined grains/cereals, vegetables, fruits, nuts, legumes, eggs, dairy products, fish, red meat, processed meat, and sugar-sweetened beverages. The Food and Agriculture Organization and World Health Organization use
6912-561: Is gripped by rubber belts roughly 20–25 cm (8–10 inches) above ground, to avoid getting grasses and weeds in the flax. The rubber belts then pull the whole plant out of the ground with the roots so the whole length of the plant fiber can be used. The plants then pass over the machine and is placed on the field crosswise to the harvester's direction of travel. The plants are left in the field for field retting . The mature plant can also be cut with mowing equipment, similar to hay harvesting, and raked into windrows. When dried sufficiently,
7056-502: Is harder to digest. Carnivores mouths are designed for tearing and biting compared to the grinding action found in herbivores. Herbivores however have comparatively longer digestive tracts and larger stomachs to aid in digesting the cellulose in plants. According to the World Health Organization (WHO), about 600 million people worldwide get sick and 420,000 die each year from eating contaminated food. Diarrhea
7200-514: Is increasingly problematic: the Sahara reportedly spreads up to 48 kilometres (30 mi) per year. The most serious famines have been caused by a combination of drought, misguided economic policies, and conflict. The 1983–85 famine in Ethiopia, for example, was the outcome of all these three factors, made worse by the Communist government's censorship of the emerging crisis. In Capitalist Sudan at
7344-512: Is limited. Raw, immature linseeds contain an amount of cyanogenic compounds and can be dangerous for monogastric animals, like horses and rabbits. Boiling removes the danger. This is not an issue in meal cake due to the processing temperature during oil extraction. Flax straw left over from the harvesting of oilseed is not very nutritious; it is tough and indigestible, and is not recommended to use as ruminant fodder, although it may be used as bedding or baled as windbreaks . Flax fiber

#17327659085527488-433: Is nontoxic when consumed in typical amounts. Typical concentrations (for example, 0.48% in a sample of defatted dehusked flax seed meal) can be removed by special processing. The soils most suitable for flax, besides the alluvial kind, are deep loams containing a large proportion of organic matter . Flax is often found growing just above the waterline in cranberry bogs. Heavy clays are unsuitable, as are soils of
7632-428: Is produced when retting, and it would corrode the metal. If the water temperature is kept at 27 °C (80 °F), the retting process under these conditions takes 4 or 5 days. If the water is any colder, it takes longer. Scum collects at the top, and an odor is given off the same as in pond retting. 'Enzymatic' retting of flax has been researched as a technique to engineer fibers with specific properties. Dressing
7776-421: Is stable against excessive oxidation when stored for nine months at room temperature, and under warehouse conditions, for 20 months at ambient temperatures. Three phenolic glucosides — secoisolariciresinol diglucoside , p-coumaric acid glucoside, and ferulic acid glucoside—are present in commercial breads containing flax seed. After crushing the seeds to extract linseed oil, the resultant linseed meal

In November 2021, the World Food Programme reported that 45 million people were "teetering on the very edge of famine" in 43 countries and that the slightest shock would push them over the precipice. This number had risen from 42 million earlier in 2021, and from 27 million in 2019. The slightest shock — be it extreme weather linked to climate change, conflict, or
8064-506: Is the most common illness caused by consuming contaminated food, with about 550 million cases and 230,000 deaths from diarrhea each year. Children under five years of age account for 40% of the burden of foodborne illness, with 125,000 deaths each year. A 2003 World Health Organization (WHO) report concluded that about 30% of reported food poisoning outbreaks in the WHO European Region occur in private homes. According to

Since the advent of industrial process for nitrogen fixation, the Haber-Bosch Process , the majority of ammonia in the world is human-made. Plants as a food source are divided into seeds, fruits, vegetables, legumes, grains and nuts. Where plants fall within these categories can vary, with botanically described fruits such as the tomato, squash, pepper and eggplant or seeds like peas commonly considered vegetables. Food

Photosynthetic plants, algae and certain bacteria often represent the lowest point of the food chains, making photosynthesis the primary source of energy and food for nearly all life on earth. Plants also absorb important nutrients and minerals from the air, natural waters, and soil. Carbon, oxygen and hydrogen are absorbed from

Animals are used as food either directly or indirectly. This includes meat, eggs, shellfish and dairy products like milk and cheese. They are an important source of protein and are considered complete proteins for human consumption as they contain all

This includes a full ban on all shipments for a short time after the attack, later extremely restrictive security checks on aid attempting to go through the blockade, and Israeli protesters blocking aid . In 2024, famine conditions struck Haiti as a result of the ongoing Haitian crisis , resulting in a reported 6,000 people suffering from starvation and 5.4 million civilians— almost half of Haiti's population— suffering from "crisis levels of hunger or worse". While food insecurity

But with laws designed to publicize the hygiene of linen textiles and the health of linseed oil, Charlemagne revived the crop in the eighth century CE . Eventually, Flanders became the major center of the European linen industry in the Middle Ages . In North America, colonists introduced flax, and it flourished there, but by
9216-540: The Netherlands had one of the most commercialized agricultural systems in Europe. They grew many industrial crops such as flax , hemp and hops . Agriculture became increasingly specialized and efficient. The efficiency of Dutch agriculture allowed for much more rapid urbanization in the late sixteenth and early seventeenth centuries than anywhere else in Europe. As a result, productivity and wealth increased, allowing

In Ethiopia it was estimated that as much as 90 percent of the national herd died, rendering rich farmers and herders destitute overnight. This coincided with drought associated with an El Niño oscillation, human epidemics of smallpox , and in several countries, intense war. The Ethiopian Great famine that afflicted Ethiopia from 1888 to 1892 cost it roughly one-third of its population. In Sudan

A heckle is a bed of "nails"—sharp, long-tapered, tempered, polished steel pins driven into wooden blocks at regular spacing. In September 2009, Canadian flax exports reportedly had been contaminated by a deregistered genetically modified cultivar called 'Triffid' that had food and feed safety approval in Canada and
10080-462: The 16th and 17th century, the feudal system began to break down, and more prosperous farmers began to enclose their own land and improve their yields to sell the surplus crops for a profit. These capitalist landowners paid their labourers with money , thereby increasing the commercialization of rural society. In the emerging competitive labour market, better techniques for the improvement of labour productivity were increasingly valued and rewarded. It
10224-436: The 1870s to the 1970s, great famines killed an average of 928,000 people a year. Since 1980, annual deaths had dropped to an average of 75,000, less than 10% of what they had been until the 1970s. That reduction was achieved despite the approximately 150,000 lives lost in the 2011 Somalia famine . Yet in 2017, the UN officially declared famine had returned to Africa, with about 20 million people at risk of death from starvation in
10368-689: The 19th century, when cotton overtook flax as the most common plant for making rag-based paper . Flax is grown on the Canadian prairies for linseed oil, which is used as a drying oil in paints and varnishes and in products such as linoleum and printing inks . Linseed meal, the by-product of producing linseed oil from flax seeds, is used as livestock fodder . Flax seeds occur in brown and yellow (golden) varieties. Most types of these basic varieties have similar nutritional characteristics and equal numbers of short-chain omega-3 fatty acids . Yellow flax seeds, called solin ( trade name " Linola "), have
10512-520: The 20th century served the geopolitical purposes of governments, including traumatizing and replacing distrusted ethnic populations in strategically important regions, rendering regions vulnerable to invasion difficult to govern by an enemy power and shifting the burden of food shortage onto regions where the distress of the population posed a lesser risk of catastrophic regime de-legitimation. Until 2017, worldwide deaths from famine had been falling dramatically. The World Peace Foundation reported that from
10656-607: The African Jaga were also more prevalent during this time frame, indicating an extreme deprivation of a primary food source. A notable period of famine occurred around the turn of the 20th century in the Congo Free State . In forming this state, Leopold used mass labor camps to finance his empire. This period resulted in the death of up to 10 million Congolese from brutality, disease and famine. Some colonial "pacification" efforts often caused severe famine, notably with
10800-520: The African crisis has been interested in the political aspects of the continent, especially the liberation of the occupied parts of it and the elimination of racism. The organization has succeeded in this area but the economic field and development has not succeeded in these fields. African leaders have agreed to waive the role of their organization in the development to the United Nations through
10944-519: The Economic Commission for Africa "ECA". Chinese scholars had kept count of 1,828 instances of famine from 108 BC to 1911 in one province or another—an average of more than one famine per year. A major famine from 1333 to 1337 killed 6 million. The four famines of 1810, 1811, 1846, and 1849 are said to have killed no fewer than 45 million people. China's Qing dynasty bureaucracy devoted extensive attention to minimizing famines with
11088-586: The International Council of Voluntary Agencies and the World Food Programme said: "Girls and boys, men and women, are being starved by conflict and violence; by inequality; by the impacts of climate change; by the loss of land, jobs of prospects; by a fight against Covid-19 that has left them even further behind". The groups warned that funding had dwindled, while money alone would not be enough by itself. Governments should step in to end conflicts and ensure humanitarian access, they said. "If no action
11232-543: The Netherlands to maintain a steady food supply. By 1650, English agriculture had also become commercialized on a much wider scale. The last peacetime famine in England was in 1623–24. There were still periods of hunger, as in the Netherlands, but no more famines ever occurred. Common areas for pasture were enclosed for private use and large scale, efficient farms were consolidated. Other technical developments included
11376-585: The Prime Minister. The government hoped that they would not "stifle private enterprise" and that their actions would not act as a disincentive to local relief efforts. Due to weather conditions, the first shipment did not arrive in Ireland until the beginning of February 1846. The maize corn was then re-sold for a penny a pound. In 1846, Peel moved to repeal the Corn Laws , tariffs on grain which kept
11520-693: The Sudan and Sahelian regions of Africa. This caused famine because even though the Sudanese Government believed there was a surplus of grain, there were local deficits across the region. In October 1984, television reports describing the Ethiopian famine as "biblical", prompted the Live Aid concerts in London and Philadelphia, which raised large sums to alleviate the suffering. A primary cause of
11664-732: The U.S. Canadian growers and the Flax Council of Canada raised concerns about the marketability of this cultivar in Europe where a zero tolerance policy exists regarding unapproved genetically modified organisms . Consequently, Triffid was deregistered in 2010 and never grown commercially in Canada or the U.S. Triffid stores were destroyed, but future exports and further tests at the University of Saskatchewan proved that Triffid persisted in at least two Canadian flax varieties, possibly affecting future crops. Canadian flax seed cultivars were reconstituted with Triffid-free seed used to plant
11808-506: The United Nations World Food Programme , famine is declared when malnutrition is widespread, and when people have started dying of starvation through lack of access to sufficient, nutritious food. The Integrated Food Security Phase Classification criteria define Phase 5 famine of acute food insecurity as occurring when all three of the following situations exist at the same time: The declaration of
11952-537: The WHO and CDC , in the USA alone, annually, there are 76 million cases of foodborne illness leading to 325,000 hospitalizations and 5,000 deaths. From 2011 to 2016, on average, there were 668,673 cases of foodborne illness and 21 deaths each year. In addition, during this period, 1,007 food poisoning outbreaks with 30,395 cases of food poisoning were reported. Flax Flax , also known as common flax or linseed ,
12096-607: The air or water and are the basic nutrients needed for plant survival. The three main nutrients absorbed from the soil for plant growth are nitrogen, phosphorus and potassium, with other important nutrients including calcium, sulfur, magnesium, iron boron, chlorine, manganese, zinc, copper molybdenum and nickel. Bacteria and other microorganisms also form the lower rungs of the food chain. They obtain their energy from photosynthesis or by breaking down dead organisms, waste or chemical compounds. Some form symbiotic relationships with other organisms to obtain their nutrients. Bacteria provide
12240-440: The apex predators, the animals that have no known predators in its ecosystem. Humans are considered apex predators. Humans are omnivores, finding sustenance in vegetables, fruits, cooked meat, milk, eggs, mushrooms and seaweed. Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Corn (maize) , wheat, and rice account for 87% of all grain production worldwide. Just over half of
12384-578: The century was the Bengal famine of 1943 , resulting both from the Japanese occupation of Burma , resulting in an influx of refugees, and blocking Burmese grain imports and a failure of the Bengali provincial Government to declare a famine , and fund relief, the imposition of grain and transport embargoes by the neighbouring provincial administrations, to prevent their own stocks being transferred to Bengal,
12528-569: The continent might be able to feed just 25% of its population by 2025, according to United Nations University (UNU)'s Ghana-based Institute for Natural Resources in Africa. Famines in the early 21st century in Africa include the 2005–06 Niger food crisis , the 2010 Sahel famine and the 2011 East Africa drought , where two consecutive missed rainy seasons precipitated the one of the worst droughts in East Africa in 60 years. An estimated 50,000 to 150,000 people are reported to have died during
12672-428: The crisis deepened. Russell's ministry introduced public works projects, which by December 1846 employed some half million Irish and proved impossible to administer. The government was influenced by a laissez-faire belief that the market would provide the food needed. It halted government food and relief works, and turned to a mixture of "indoor" and "outdoor" direct relief; the former administered in workhouses through
12816-448: The crop steadily spread, reaching as far as Switzerland and Germany by 5,000 years ago. In China and India, domesticated flax was cultivated at least 5,000 years ago. Flax was cultivated extensively in ancient Egypt , where the temple walls had paintings of flowering flax, and mummies were embalmed using linen. Egyptian priests wore only linen, as flax was considered a symbol of purity. Phoenicians traded Egyptian linen throughout
12960-469: The deadly interplay of both hunger drivers — could push tens of millions of people into irreversible peril, a prospect the agency had been warning of for more than a year. Afghanistan was becoming the world's largest humanitarian crisis, with the country's needs surpassing those of the other worst-hit countries — Ethiopia , South Sudan , Syria and even Yemen . In 2023 and 2024, the Israeli response to
13104-406: The draining of marshes, more efficient field use patterns, and the wider introduction of industrial crops. These agricultural developments led to wider prosperity in England and increasing urbanization. By the end of the 17th century, English agriculture was the most productive in Europe. In both England and the Netherlands, the population stabilized between 1650 and 1750, the same time period in which
13248-676: The drought was brief the main cause of death in Rwanda was due to Belgian prerogatives to acquisition grain from their colony (Rwanda). The increased grain acquisition was related to WW2. This and the drought caused 300,000 Rwandans to perish. From 1967 to 1969 large scale famine occurred in Biafra and Nigeria due to a government blockade of the Breakaway territory . It is estimated that 1.5 million people died of starvation due to this famine. Additionally, drought and other government interference with
13392-412: The early 20th century, cheap cotton and rising farm wages had caused production of flax to become concentrated in northern Russia, which came to provide 90% of the world's output. Since then, flax has lost its importance as a commercial crop , due to the easy availability of more durable fibres. Flax is grown for its seeds, which can be ground into a meal or turned into linseed oil , a product used as
13536-434: The escalating disaster was effectively suppressed. When the leadership did become aware of the scale of the famine, it did little to respond, and continued to ban any discussion of the cataclysm. This blanket suppression of news was so effective that very few Chinese citizens were aware of the scale of the famine, and the greatest peacetime demographic disaster of the 20th century only became widely known twenty years later, when
13680-567: The essential amino acids that the human body needs. One 4-ounce (110 g) steak, chicken breast or pork chop contains about 30 grams of protein. One large egg has 7 grams of protein. A 4-ounce (110 g) serving of cheese has about 15 grams of protein. And 1 cup of milk has about 8 grams of protein. Other nutrients found in animal products include calories, fat, essential vitamins (including B12) and minerals (including zinc, iron, calcium, magnesium). Food products produced by animals include milk produced by mammary glands , which in many cultures
13824-554: The failure to implement India wide rationing by the central Delhi authority, hoarding and profiteering by merchants, medieval land management practices, an Axis powers denial program that confiscated boats once used to transport grain, a Delhi administration that prioritised supplying, and offering medical treatment to the British Indian Army, War workers, and Civil servants, over the populace at large, incompetence and ignorance, and an Imperial War Cabinet initially leaving
13968-446: The famine (one of the largest seen in the country) is that Ethiopia (and the surrounding Horn) was still recovering from the droughts which occurred in the mid-late 1970s. Compounding this problem was the intermittent fighting due to civil war , the government 's lack of organization in providing relief, and hoarding of supplies to control the population. Ultimately, over 1 million Ethiopians died and over 22 million people suffered due to
14112-401: The fiber. The stems are then pulled through "hackles", which act like combs to remove the straw and some shorter fibers out of the long fiber. Several methods are used for retting flax. It can be retted in a pond, stream, field, or tank. When the retting is complete, the bundles of flax feel soft and slimy, and quite a few fibers are standing out from the stalks. When wrapped around a finger,
14256-407: The field in the spring. Two ways are used to harvest flax fiber, one involving mechanized equipment (combines), and a second method, more manual and targeting maximum fiber length. Flax for fiber production is usually harvested by a specialized flax harvester. Usually built on the same machine base as a combine, but instead of the cutting head it has a flax puller. The flax plant is turned over and
14400-402: The flax is the process of removing the straw from the fibers. Dressing consists of three steps: breaking, scutching, and heckling. The breaking breaks up the straw. Some of the straw is scraped from the fibers in the scutching process, and finally, the fiber is pulled through heckles to remove the last bits of straw. Breaking breaks up the straw into short segments. Scutching removes some of
14544-399: The flax straw is not harvested, typically, it is burned, since the stalks are quite tough and decompose slowly ( i.e. , not in a single season). Formed into windrows from the harvesting process, the straw often clogs up tillage and planting equipment. Flax straw that is not of sufficient quality for fiber uses can be baled to build shelters for farm animals, or sold as biofuel, or removed from
14688-547: The food supply caused 500 thousand Africans to perish in Central and West Africa. Famine recurred in the early 1970s, when Ethiopia and the west African Sahel suffered drought and famine . The Ethiopian famine of that time was closely linked to the crisis of feudalism in that country, and in due course helped to bring about the downfall of the Emperor Haile Selassie . The Sahelian famine was associated with
14832-550: The form of starch, fructose, glucose and other sugars. Most vitamins are found from plant sources, with exceptions of vitamin D and vitamin B 12 . Minerals can also be plentiful or not. Fruit can consist of up to 90% water, contain high levels of simple sugars that contribute to their sweet taste, and have a high vitamin C content. Compared to fleshy fruit (excepting Bananas) vegetables are high in starch, potassium , dietary fiber, folate and vitamins and low in fat and calories. Grains are more starch based and nuts have
14976-410: The inner woody part springs away from the fibers. Pond retting is the fastest. It consists of placing the flax in a pool of water which will not evaporate. It generally takes place in a shallow pool which will warm up dramatically in the sun; the process may take from a few days to a few weeks. Pond-retted flax is traditionally considered of lower quality, possibly because the product can become dirty, and
15120-627: The introduction of drought-resistant crops and new methods of food production such as agro-forestry. Piloted in Ethiopia in the 1990s it has spread to Malawi, Uganda, Eritrea and Kenya. In an analysis of the programme by the Overseas Development Institute , CABDA's focus on individual and community capacity-building is highlighted. This enables farmers to influence and drive their own development through community-run institutions, bringing food security to their household and region. The organization of African unity and its role in
15264-789: The issue to the Colonial administration to resolve, than to the original local crop failures, and blights. A few of the great famines of the late 20th century were: the Biafran famine in the 1960s, the Khmer Rouge -caused famine in Cambodia in the 1970s, the North Korean famine of the 1990s , and the Ethiopian famine of 1983–1985 . Approximately 3 million died as a consequence of the Second Congo War . The Ethiopian famine
15408-531: The late 18th century and early 19th century. There was famine in Tripoli in 1784, and in Tunis in 1785. According to John Iliffe, "Portuguese records of Angola from the 16th century show that a great famine occurred on average every seventy years; accompanied by epidemic disease, it might kill one-third or one-half of the population, destroying the demographic growth of a generation and forcing colonists back into
15552-493: The mid-19th century and the onset of the Industrial Revolution , it became possible for governments to alleviate the effects of famine through price controls , large scale importation of food products from foreign markets, stockpiling, rationing , regulation of production and charity . The Great Famine of 1845 in Ireland was one of the first famines to feature such intervention, although the government response
15696-563: The mid-19th century, the system broke down. Thus the 1867–68 famine under the Tongzhi Restoration was successfully relieved but the Great North China Famine of 1877–78, caused by drought across northern China, was a catastrophe. The province of Shanxi was substantially depopulated as grains ran out, and desperately starving people stripped forests, fields, and their very houses for food. Estimated mortality
15840-587: The middle part of the 20th century, agriculturalists, economists and geographers did not consider Africa to be especially famine prone. From 1870 to 2010, 87% of deaths from famine occurred in Asia and Eastern Europe, with only 9.2% in Africa. There were notable counter-examples, such as the famine in Rwanda during World War II and the Malawi famine of 1949, but most famines were localized and brief food shortages. Although
15984-507: The new money to purchase manufactured goods. The agricultural and social developments encouraging increased food production were gradually taking place throughout the 16th century, but took off in the early 17th century. By the 1590s, these trends were sufficiently developed in the rich and commercialized province of Holland to allow its population to withstand a general outbreak of famine in Western Europe at that time. By that time,
16128-701: The northern part of Nigeria, in South Sudan , in Yemen , and in Somalia . On 20 April 2021, hundreds of aid organizations from around the world wrote an open letter to The Guardian newspaper, warning that millions of people in Yemen , Afghanistan , Ethiopia , South Sudan , Burkina Faso , Democratic Republic of the Congo , Honduras , Venezuela , Nigeria , Haiti , Central African Republic , Uganda , Zimbabwe and Sudan faced starvation. Organizations including
16272-503: The number of deaths by famine markedly. That said, many African countries are not self-sufficient in food production, relying on income from cash crops to import food. Agriculture in Africa is susceptible to climatic fluctuations, especially droughts which can reduce the amount of food produced locally. Other agricultural problems include soil infertility , land degradation and erosion , swarms of desert locusts , which can destroy whole crops, and livestock diseases. Desertification
16416-467: The organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of
16560-540: The period. In 2012, the Sahel drought put more than 10 million people in the western Sahel at risk of famine (according to a Methodist Relief & Development Fund (MRDF) aid expert), due to a month-long heat wave. Today, famine is most widespread in Sub-Saharan Africa , but with exhaustion of food resources, overdrafting of groundwater , wars, internal struggles, and economic failure, famine continues to be
16704-413: The plant that can be eaten, including roots, stems, leaves, flowers, bark or the entire plant itself. These include root vegetables (potatoes and carrots), bulbs (onion family), flowers (cauliflower and broccoli), leaf vegetables ( spinach and lettuce) and stem vegetables (celery and asparagus ). The carbohydrate, protein and lipid content of plants is highly variable. Carbohydrates are mainly in
16848-671: The plant, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant and appears to have been domesticated just once from the wild species Linum bienne , called pale flax. The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium . Several other species in the genus Linum are similar in appearance to L. usitatissimum , cultivated flax, including some that have similar blue flowers, and others with white, yellow, or red flowers. Some of these are perennial plants, unlike L. usitatissimum , which
16992-495: The poor, and price regulation, as part of a state guarantee of subsistence to the peasantry (known as ming-sheng ). However the Taiping Rebellion of the 1850s disrupted the granary relief system such that 1850 to 1873 saw the population of China drop by over 30 million people from early deaths and missing births. When a stressed monarchy shifted from state management and direct shipments of grain to monetary charity in
17136-536: The poor. Addressing food scarcity requires sustainable agricultural practices, improved food distribution systems, and coordinated global efforts to alleviate poverty and inequality. The cyclical occurrence of famine has been a mainstay of societies engaged in subsistence agriculture since the dawn of agriculture itself. The frequency and intensity of famine has fluctuated throughout history, depending on changes in food demand, such as population growth , and supply-side shifts caused by changing climatic conditions. In
17280-569: The price of bread artificially high. The famine situation worsened during 1846 and the repeal of the Corn Laws in that year did little to help the starving Irish; the measure split the Conservative Party, leading to the fall of Peel's ministry. In March, Peel set up a programme of public works in Ireland. Despite this promising start, the measures undertaken by Peel's successor, Lord John Russell , proved comparatively "inadequate" as
17424-470: The process. Collectivisation undermined incentives for the investment of labor and resources in agriculture; unrealistic plans for decentralized metal production sapped needed labor; unfavorable weather conditions; and communal dining halls encouraged overconsumption of available food. Such was the centralized control of information and the intense pressure on party cadres to report only good news—such as production quotas met or exceeded—that information about
17568-438: The prolonged drought, which lasted roughly 2 years. In 1992 Somalia became a war zone with no effective government, police, or basic services after the collapse of the dictatorship led by Siad Barre and the split of power between warlords. This coincided with a massive drought, causing over 300,000 Somalis to perish. Since the start of the 21st century, more effective early warning and humanitarian response actions have reduced
17712-527: The repression of the Maji Maji revolt in Tanganyika in 1906. The introduction of cash crops such as cotton, and forcible measures to impel farmers to grow these crops, sometimes impoverished the peasantry in many areas, such as northern Nigeria, contributing to greater vulnerability to famine when severe drought struck in 1913. A large-scale famine occurred in Ethiopia in 1888 and in succeeding years, as
17856-733: The river valleys." The first documentation of weather in West-Central Africa occurred around the mid-16th to 17th centuries in areas such as Luanda Kongo, however, not much data was recorded on the issues of weather and disease except for a few notable documents. The only records obtained are of violence between Portuguese and Africans during the Battle of Mbwila in 1665. In these documents the Portuguese wrote of African raids on Portuguese merchants solely for food, giving clear signs of famine. Additionally, instances of cannibalism by
18000-519: The same date, drought and economic crisis combined with denials of any food shortage by the then-government of President Gaafar Nimeiry , to create a crisis that killed perhaps 250,000 people—and helped bring about a popular uprising that overthrew Nimeiry. Numerous factors make the food security situation in Africa tenuous, including political instability, armed conflict and civil war , corruption and mismanagement in handling food supplies, and trade policies that harm African agriculture. An example of
18144-492: The slowly growing crisis of pastoralism in Africa, which has seen livestock herding decline as a viable way of life over the last two generations. Famines occurred in Sudan in the late-1970s and again in 1990 and 1998. The 1980 famine in Karamoja , Uganda was, in terms of mortality rates, one of the worst in history. 21% of the population died, including 60% of the infants. In the 1980s, large scale multilayer drought occurred in
18288-399: The stalk. The first step in this process is retting , which is the process of rotting away the inner stalk, leaving the outer parts intact. At this point, straw, or coarse outer stem ( cortex and epidermis ), is still remaining. To remove this, the flax is "broken", the straw is broken up into small, short bits, while the actual fiber is left unharmed. Scutching scrapes the outer straw from
18432-401: The straw (stem) from the fiber, and one for further separating the broken straw and matter from the fiber. The second part of the process brings the flax into a state for the very finest purposes, such as lace , cambric , damask , and very fine linen . This second part is performed by a refining machine. Before the flax fibers can be spun into linen, they must be separated from the rest of
18576-698: The sweeping changes to agriculture occurred. Famine still occurred in other parts of Europe, however. In Eastern Europe , famines occurred as late as the twentieth century. Because of the severity of famine, it was a chief concern for governments and other authorities. In pre-industrial Europe, preventing famine, and ensuring timely food supplies, was one of the chief concerns of many governments, although they were severely limited in their options due to limited levels of external trade, infrastructure, and bureaucracy generally too rudimentary to effect real relief. Most governments were concerned by famine because it could lead to revolt and other forms of social disruption. By
18720-448: The tastes that provide the most energy are the most pleasant to eat while others are not enjoyable, although humans in particular can acquire a preference for some substances which are initially unenjoyable. Water, while important for survival, has no taste. Sweetness is almost always caused by a type of simple sugar such as glucose or fructose , or disaccharides such as sucrose , a molecule combining glucose and fructose. Sourness
18864-523: The top. Other aspects of the web include detrovores (that eat detritis ) and decomposers (that break down dead organisms). Primary producers include algae, plants, bacteria and protists that acquire their energy from sunlight. Primary consumers are the herbivores that consume the plants, and secondary consumers are the carnivores that consume those herbivores. Some organisms, including most mammals and birds, diet consists of both animals and plants, and they are considered omnivores. The chain ends with
19008-400: The usable flax fibers from other components requires pulling the stems through a hackle and/or beating the plants to break them. Flax processing is divided into two parts: the first part is generally done by the farmer, to bring the flax fiber into a fit state for general or common purposes. This can be performed by three machines: one for threshing out the seed, one for breaking and separating
19152-518: The use of flax as an industrial fiber. Flax seeds are 7% water, 18% protein , 29% carbohydrates , and 42% fat (table). In 100 grams (3.5 oz) as a reference amount, flax seeds provide 534 kilocalories and contain high levels (20% or more of the Daily Value , DV) of protein, dietary fiber , several B vitamins , and dietary minerals . Flax seeds are especially rich in thiamine , magnesium , and phosphorus (DVs above 90%) (table). As
19296-416: The veil of censorship began to lift. The exact number of famine deaths during 1958–1961 is difficult to determine, and estimates range from 18 million to at least 42 million people, with a further 30 million cancelled or delayed births. It was only when the famine had wrought its worst that Mao reversed agricultural collectivisation policies, which were effectively dismantled in 1978. China has not experienced
19440-458: The waters used for the process. In field retting, the flax is laid out in a large field, and dew is allowed to collect on it. This process normally takes a month or more, but is generally considered to provide the highest quality flax fibers, and it produces the least pollution. Retting can also be done in a plastic trash can or any type of water-tight container of wood, concrete, earthenware, or plastic. Metal containers will not work, as an acid
19584-403: The world's crops are used to feed humans (55 percent), with 36 percent grown as animal feed and 9 percent for biofuels . Fungi and bacteria are also used in the preparation of fermented foods like bread , wine , cheese and yogurt . During photosynthesis , energy from the sun is absorbed and used to transform water and carbon dioxide in the air or soil into oxygen and glucose. The oxygen
19728-675: The year 1888 is remembered as the worst famine in history, on account of these factors and also the exactions imposed by the Mahdist state . The oral traditions of the Himba people recall two droughts from 1910 to 1917. From 1910 to 1911 the Himba described the drought as "drought of the omutati seed", also called omangowi , the fruit of an unidentified vine that people ate during the time period. From 1914 to 1916, droughts brought katur' ombanda or kari' ombanda 'the time of eating clothing'. For
19872-441: Was defined as three successive years of crop failure , crop yields of one-third or one-half normal, and large populations in distress. "Famine" further included a rise in food prices above 140% of "normal", the movement of people in search of food, and widespread mortality. The Commission identified that the loss of wages from lack of employment of agricultural labourers and artisans were the cause of famines. The Famine Code applied
20016-701: Was discovered in Euonymeia , Greece. The best grades are used for fabrics such as damasks , lace , and sheeting . Coarser grades are used for the manufacturing of twine and rope , and historically, for canvas and webbing equipment . Flax fiber is a raw material used in the high-quality paper industry for the use of printed banknotes , laboratory paper ( blotting and filter ), rolling paper for cigarettes , and tea bags . Flax mills for spinning flaxen yarn were invented by John Kendrew and Thomas Porthouse of Darlington , England , in 1787. New methods of processing flax have led to renewed interest in
