The Combined Food Board was a temporary World War II government agency that allocated the combined economic resources of the United States and the United Kingdom. It was set up by President Franklin D. Roosevelt and Prime Minister Winston Churchill on June 9, 1942.  Canada, after insisting on its economic importance, was given a place on the board in November, 1942.  At first the Board was a pawn in a battle between the U.S. Department of Agriculture and the U.S. War Food Administration. After that was resolved, the Board ran smoothly, and effectiveness increased. Its major achievement was the multi-nation commodity committees that it set up in 1945, which became the International Emergency Food Council. It tried to organize responses to a massive shortage of food in war-torn areas. It closed in 1946. 
The mission of the Combined Food Board set out by Roosevelt and Churchill was twofold: 
This board will be composed of the U.S. Secretary of Agriculture (Mr. Claude Wickard) and the head of the British Food Mission (Mr. R. H. Brand), who will represent and act under the instructions of the Minister of Food. The purpose of the Board shall be to co-ordinate and obtain a planned and expeditious utilisation of the food resources of the United Nations. The duties of the board shall be to consider, investigate, inquire into, and formulate plans with regard to any question in respect of which the U.S. and British Governments have a common concern, relating to supply, production, transportation, disposal, allocation or distribution in or to any part of the world, of foods, agricultural materials from which foods are derived, and equipment and non food materials used in the production of such foods; and agricultural materials, and to make recommendations to the U.S. and British Governments in respect of any such questions. To work in collaboration with others of the United Nations towards the best utilisation of their food resources and, in collaboration with any interested nation or nations, to formulate plans and recommendations for development, expansion, purchase, or other effective use of their food resources. The Board shall be entitled to receive from any agency of the U.S. Government and any department of the British Government information relating to any matter with regard to which the board is competent to make recommendations to those Governments, and in principle the entire food resources of Great Britain and the United States will be deemed to be in a common pool about which fullest information will be interchanged.
William Mabane, the Parliamentary Secretary to the Minister of Food, explained to Parliament in May 1943 that, "Food strategy was no mere domestic matter, and a scramble between the United Nations for supplies would be disastrous. Combined Food Board machinery had therefore been set up to prevent competitive buying of foodstuffs in short supply and remove any grievance that one country was going short while there was a surplus elsewhere." 
The biggest problem was in limited shipping space in convoys bringing foods from the Western Hemisphere, especially with the heavy demands on shipping imposed by the landings in North Africa in November, 1942. There was barely enough space for bringing in even grain for current needs. Lord Woolton, the Minister of Food, urgently called on Britons to eat more potatoes and less bread.  He introduced the National Loaf that used much less shipping space, but which consumers could barely stomach.  
Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, mobilizes all of the resources of society to fight the war, and gives priority to warfare over non-combatant needs.
Rationing is the controlled distribution of scarce resources, goods, services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one's allowed portion of the resources being distributed on a particular day or at a particular time. There are many forms of rationing, although rationing by price is most prevalent.
The Ministry of Agriculture, Fisheries and Food (MAFF) was a United Kingdom government department created by the Board of Agriculture Act 1889 and at that time called the Board of Agriculture, and then from 1903 the Board of Agriculture and Fisheries, and from 1919 the Ministry of Agriculture and Fisheries. It attained its final name in 1955 with the addition of responsibilities for the British food industry to the existing responsibilities for agriculture and the fishing industry, a name that lasted until the Ministry was dissolved in 2002, at which point its responsibilities had been merged into the Department for Environment, Food and Rural Affairs (Defra).
A war economy or wartime economy is the set of contingencies undertaken by a modern state to mobilize its economy for war production. Philippe Le Billon describes a war economy as a "system of producing, mobilizing and allocating resources to sustain the violence." Some measures taken include the increasing of Taylor rates as well as the introduction of resource allocation programs. Approaches to the reconfiguration of the economy differ from country to country.
Victory gardens, also called war gardens or food gardens for defense, were vegetable, fruit, and herb gardens planted at private residences and public parks in the United States, United Kingdom, Canada, Australia and Germany during World War I and World War II. In wartime, governments encouraged people to plant victory gardens not only to supplement their rations but also to boost morale. They were used along with Rationing Stamps and Cards to reduce pressure on the public food supply. Besides indirectly aiding the war effort, these gardens were also considered a civil "morale booster" in that gardeners could feel empowered by their contribution of labor and rewarded by the produce grown. This made victory gardens a part of daily life on the home front.
Frederick James Marquis, 1st Earl of Woolton, was an English businessman and politician.
The Minister of Food Control (1916–1921) and the Minister of Food (1939–1958) were British government ministerial posts separated from that of the Minister of Agriculture. In the Great War the Ministry sponsored a network of canteens known as National Kitchens. In the Second World War a major task of the Ministry was to oversee rationing in the United Kingdom arising out of World War II. The Minister was assisted by a Parliamentary Secretary. The Parliamentary Under Secretary of State for Food and Animal Welfare (2018–present) was appointed at the Department for the Environment, Food and Rural Affairs to ensure the continued supply of sufficient food during the Brexit process.
Rationing was introduced temporarily by the British government several times during the 20th century, during and immediately after a war.

The War Production Board (WPB) was an agency of the United States government that supervised war production during World War II. President Franklin D. Roosevelt established it in January 1942, with Executive Order 9024. The WPB replaced the Supply Priorities and Allocation Board and the Office of Production Management.
The 'home front' covers the activities of the civilians in a nation at war. World War II was a total war; homeland production became even more invaluable to both the Allied and Axis powers. Life on the home front during World War II was a significant part of the war effort for all participants and had a major impact on the outcome of the war. Governments became involved with new issues such as rationing, manpower allocation, home defense, evacuation in the face of air raids, and response to occupation by an enemy power. The morale and psychology of the people responded to leadership and propaganda. Typically women were mobilized to an unprecedented degree.
The Soviet famine of 1946–1947 was a major famine in the Soviet Union that lasted from mid-1946 to the winter of 1947 to 1948.
The War Food Administration was a United States government agency that existed from 1943 to 1945. The War Food Administration was responsible for the production and distribution of food to meet war and essential civilian needs during World War II. It was a predecessor of the Farm Service Agency.
The Combined Production and Resources Board was a temporary World War II government agency that allocated the combined economic resources of the United States and Britain. It was set up by President Franklin D. Roosevelt and Prime Minister Winston Churchill on June 9, 1942. Canada, after insisting on its economic importance, was given a place on the board in November, 1942. The Board closed down at the end of December 1945.
The Combined Raw Materials Board was a temporary World War II government agency that allocated the combined economic resources of the United States and Britain. It was set up by President Franklin D. Roosevelt and Prime Minister Winston Churchill on January 26, 1942. Later Canada participated as an associated member in many of the Board's decisions.
The Combined Munitions Assignments Board was a major government agency for the U.S. and Britain in World War II. With Harry Hopkins, Roosevelt's top advisor in charge, it took control of the allocation of war supplies and Lend lease aid to the Allies, especially Britain and the Soviet Union.
The Combined Shipping Adjustment Board or Combined Shipping Board was a joint American-British war agency 1942-45 nominally in charge of commercial shipping. It proved ineffective as much more powerful boards, such as the Combined Munitions Assignments Board, ignored it. The U.S. Army and Navy controlled most shipping and refused to share responsibility with the Board as did the powerful War Shipping Administration. For practical purposes the agency was inactive by spring 1943.
Rationing is the controlled distribution of scarce resources, goods, or services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one person's allotted portion of the resources being distributed on a particular day or at a particular time.
The Battle of the Harvests is an 18-minute 1942 Canadian documentary film, made by the National Film Board of Canada (NFB) as part of the wartime Canada Carries On series.
