Question: Which agricultural commodity with the highest worldwide production beats the most widely consumed staple food of Asia and the most important crop of Thailand for some 60 percent of Thailand's 13 million farmers?
Context: Agricultural biodiversity is a sub-set of general biodiversity.  It includes all forms of life directly relevant to agriculture: rare seed varieties and animal breeds (farm biodiversity), but also many other organisms such as soil fauna, weeds, pests, predators, and all of the native plants and animals (wild biodiversity) existing on and flowing through the farm.  However, most attention in this field is given to crop varieties and to crop wild relatives.  Cultivated varieties can be broadly classified into “modern varieties” and “farmer's or traditional varieties”.  Modern varieties are the outcome of formal breeding and are often characterized as 'high yielding'.  For example, the short straw wheat and rice varieties of the Green Revolution.  In contrast, farmer's varieties (also known as landraces) are the product of (breeding and) selection carried out by farmers.  Together, these varieties represent high levels of genetic diversity and are therefore the focus of most crop genetic resources conservation efforts.  Agricultural biodiversity will also be absolutely essential to cope with the predicted impacts of climate change, not simply as a source of traits but as the underpinnings of more resilient farm ecosystems.  Agricultural biodiversity is the basis of our agricultural food chain, developed and safeguarded by farmers, livestock breeders, forest workers, fishermen and indigenous peoples throughout the world.  The use of agricultural biodiversity (as opposed to non diverse production methods) can contribute to food security and livelihood security. Market price support (MPS) is an indicator, developed by the OECD, used in the calculation of Producer and Consumer Subsidy Equivalents (PSE/CSE).  MPS is the annual monetary value of gross transfers from consumers and taxpayers to agricultural producers arising from policy measures creating a gap between domestic market prices and border prices of a specific agricultural commodity measured at the farm gate level.  Conditional on the production of a specific commodity, MPS includes the transfer to producers associated with both production for domestic use and exports and is measured by the price gap applied to current production.  The MPS is net of producer levies on sales of the specific commodity or penalties for not respecting regulations such as production quotas (price levies).  In the case of livestock production MPS is net of the market price support on domestically produced coarse grains and oilseeds used as animal feed (excess feed cost). Cassava ("Manihot esculenta", "manioca" in French language) production is important to the economy of the Republic of the Congo as it is its prime crop.  The importance of cassava consumption is reflected in the country's popular song, "The Congolese Love Cassava".  It is consumed in several forms, and marketed as paste, "cossettes", "foufou" (flour), and "chikwangue".  As a staple food crop, cassava is grown in most parts of the country, except the southern region where the crops grown are banana and plantains.  Cassava and yams are the primary subsistence crops grown in the country's valleys, with farmers producing five harvests per year.  The Republic of the Congo, as of 1996, was the world's second largest consumer of cassava after Zaire, now known as the Democratic Republic of the Congo. Rice production was a very integral part of the Haitian economy, as it has been farmed in Haiti for over two hundred years.  The origin of this rice has been traced back to West African agriculture.  Rice is a staple food for most Haitians but it has become a commodity in the sense that Haiti is no longer self-sufficient in producing rice for the country.  Haiti maintained dependency on their own agriculture of rice until the 1980s.  In the mid-1980s Haiti was no longer producing substantial amounts of rice and by the 1990s Haiti held a greater reliance on imports rather than domestic rice production.  The decline in rice production had devastating consequences for Haiti’s rural population.  Many Haitian farmers, traders, and millers faced unemployment and relocation.  Because farming was their livelihood, many could not find adequate work with their skill set.  The Adoption of trade liberalization policies and environmental degradation are said to be the two factors that have caused Haiti’s decline in rice production.  These policies have lowered the rice import tariff so that it is now less than any other Caribbean nation.  The tariff is at three percent causing a dumping ground of rice in Haiti.  Many accuse the United States of purposefully depositing all of their rice into Haiti.  In 1985 the local rice production was at 163,296 metric tons while the US imports were only at 7,337 metric tons counting for a total of 170,663 metric tons.  Now compare that to the year 2000 when local production was at 130,000 and US imports ascended to 219,590 leaving a total of 349,590 metric tons of rice.  Since 1995 there has been over $13 billion in subsidies given to American rice exportation by the United States government.  Haiti has now become inundated with rice. Rice is the seed of the grass species "Oryza sativa" (Asian rice) or "Oryza glaberrima" (African rice).  As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia.  It is the agricultural commodity with the third-highest worldwide production (rice, 741.5 million tonnes in 2014), after sugarcane (1.9 billion tonnes) and maize (1.0 billion tonnes). Sorghum (Sorghum bicolor) comes from the Latin name “Syrucum (granum)” which means “grain of Syria” however it originated in eastern Africa.  Sorghum is an important species of the grass family, Paceae, and is considered the world’s fifth most important cereal crop.  There are many diverse and wild types of Sorghum, however there are seven basic races, the most common in Asia are Durra and Sballu.  Sorghum is an important staple crop for more than 500 million people in sub-Saharan Africa and South Asia, including many people in Nepal.  Sorghum is grown on more than 48 ha area around the world.  In statistics collected from 1992-1994 about general millet, Nepal had an area of 0.21 million ha, with a yield rate of 1.14 (t/ha), and produced around 0.24 million tons of Sorghum.  The entirety of the crop is highly valued, both the grain and the stem are very useful.  Sorghum can be cooked in many different ways for food with a high nutritional content, among many other uses.  Overall Sorghum is a very important crop worldwide. Agriculture in Myanmar (also known as Burma) is the main industry in the country, accounting for 60 percent of the GDP and employing some 65 percent of the labour force.  Burma was once Asia's largest exporter of rice, and rice remains the country's most crucial agricultural commodity. This is a list of rice dishes from all over the world, arranged alphabetically.  Rice is the seed of the monocot plants "Oryza sativa" (Asian rice) or "Oryza glaberrima" (African rice).  As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia and the West Indies.  It is the grain with the second-highest worldwide production, after maize (corn), according to data for 2010. The agriculture in Thailand is highly competitive, diversified and specialised and its exports are very successful internationally.  Rice is the country's most important crop, with some 60 percent of Thailand's 13 million farmers growing it on fully half of Thailand's cultivated land.  Thailand is a major exporter in the world rice market.  Rice exports in 2014 amounted to 1.3 percent of GDP.  Agricultural production as a whole accounts for an estimated 9-10.5 percent of Thai GDP.  Forty percent of the population work in agriculture-related jobs.  The farmland they work was valued at US$2,945 per rai (0.395 acre) in 2013. RML AgTech Pvt. Ltd.
