Agriculture
Agriculture encompasses crop and livestock production, aquaculture, fisheries and forestry for food and non-food products.[1] Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the twentieth century, industrial agriculture based on large-scale monocultures came to dominate agricultural output.
Today, small farms produce about a third of the world's food, but large farms are prevalent.[2] The largest one percent of farms in the world are greater than 50 hectares and operate more than 70 percent of the world's farmland.[2] Nearly 40 percent of agricultural land is found on farms larger than 1,000 hectares.[2] However, five of every six farms in the world consist of less than two hectares and take up only around 12 percent of all agricultural land.[2] Farms and farming greatly influence rural economics and greatly shape rural society, effecting both the direct agricultural workforce and broader businesses that support the farms and farming populations.
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, eggs, and fungi. Global agricultural production amounts to approximately 11 billion tonnes of food,[3] 32 million tonnes of natural fibres[4] and 4 billion m3 of wood.[5] However, around 14 percent of the world's food is lost from production before reaching the retail level.[6]
Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, and technological developments have sharply increased crop yields, but also contributed to ecological and environmental damage. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and environmental damage. Environmental issues include contributions to climate change, depletion of aquifers, deforestation, antibiotic resistance, and other agricultural pollution. Agriculture is both a cause of and sensitive to environmental degradation, such as biodiversity loss, desertification, soil degradation, and climate change, all of which can cause decreases in crop yield. Genetically modified organisms are widely used, although some countries ban them.
Romford is a large town in East London, England, 14 miles (23 km) northeast of Charing Cross. Part of the London Borough of Havering, the town is one of the major metropolitan centres of Greater London identified in the London Plan.[2]
Historically part of the ancient parish of Hornchurch in the Becontree hundred of Essex, it has been a market town since 1247. It formed the administrative centre of the liberty of Havering until that liberty was dissolved in 1892, and became a civil parish of its own in 1849.[3][4] Good road links to London and the opening of the railway station in 1839 were key to the development of the town.[3] The economic history of Romford is characterised by a shift from agriculture to light industry and then to retail and commerce.[3]
As part of the suburban growth of London throughout the 20th century, Romford significantly expanded and increased in population, becoming a municipal borough in 1937. In 1965, following reform of local government in London, it merged with the Hornchurch Urban District to form the London Borough of Havering, and was incorporated into Greater London.[5][6][7] Today, it is one of the largest commercial, retail, entertainment and leisure districts in London and has a well-developed night-time economy.[8][9] The population of Romford, as of the 2011 census, was 122,854.[10]
