These farms use machines and new technologies to become as efficient and cost-effective as possible. Extensive Farming Extensive farming is the direct opposite of intensive farming. The farms are large in comparison to the money injected into them or the labour used. The cattle ranches of central Australia area good example of extensive agriculture, where often only a few farm workers are responsible for thousands of acres of farmland. Subsistence Farming Subsistence farmers only produce enough to feed themselves and their family, without having any more to sell for profit. This is the most common form of farming in developing countries. Commercial Farming Commercial farming involves farming for a profit. The farmer is growing crops or rearing animals to sell for as much money as possible. These farms can be arable (just growing crops), pastoral (just rearing animals) or mixed (both arable and pastoral). Most of the farming in developed countries is commercial farming of one type or another. 2

3 Types of Farming in the UK The main types of farming that you would find in the UK are arable, dairying and hill farming. Many farms are actually mixing some or all of these in an attempt to make more money. Most farming in Britain tends to be intensive although some of the hill farms of Wales and Scotland could be described as extensive. All of them are commercial.

Hill Farming (sheep) (e.g. Wales) Cool summers, cold winters and plenty of rainfall all contribute to these areas being unsuitable for arable farming but good for grass growth. Thin, poor soils that can be easily eroded and would not be good enough for other forms of farming. Hilly, steep land that would not be suitable for machinery or cattle. Sheep can cope with the slopes though.

Give reasons for your answer. 3 marks Case Study: Commercial Farming in East Anglia East Anglia includes the counties of Norfolk, Cambridgeshire, Suffolk and the northern part of Essex. It is one of the most important arable farming regions in the UK mostly because of its physical advantages Arable farming in East Anglia is highly mechanised using combine harvesters and specialised machinery. It is also commercial (mostly the crops are cash crops sold for profits to the local mills who use it for food production for humans and animal feed). Sugar beet is produced in the UK and is sent to UK refineries such as silver spoon. Physical Factors There are a number of physical factors that makes arable farming in this area Relief: the land is very flat and is mostly 100m above sea level this makes it easy to use machinery and roads and railways have easily been constructed. Soils: mostly fertile boulder clays that were laid down during the last ice age are good for growing cereals, sugar beet and potatoes. Loam soils are good for growing vegetables, fruit and cereals and retain the plant foods and moisture. Climate: Rainfall is mostly in the region of mm per year. There are long warm summers with average temperatures of 17 degrees and long hours of sunshine in the summer which allow sufficient crop growth and the ability to ripen cereal crops. Human Factors Location: it is situated in the east of England to the North of London which means that it is close to a good market for the produce. There is a good motorway network to the most densely populated regions of the UK and also a good east coast railway line which means rapid transport of produce (this is important with perishable food stuff) Politics: Since joining the EU many of the farmers in East Anglia have benefited from the Common Agricultural Policy (CAP) as they have received subsidies for growing certain types of cereal crops such as wheat, oilseed rape and linseed. 4

5 Changes in UK Farming The Common Agricultural Policy: This was a policy brought in by the EU in 1962 with a number of aims: It aimed to increase agricultural production in member countries. It aimed to improve the standard of living experienced by farmers. It aimed to maintain prices and supplies of food at a reasonable cost to the consumers. Some of the methods that it used included subsidies and minimum pricing. Farmers were encouraged to produce as much as they could, and the EU guaranteed that it would buy it all. This led to huge surpluses in butter, milk, cereals and even wine. The CAP led to the following changes: 1. Improved Technology Machinery has taken over form manual labour on most farms. Although costly to buy, machines like tractors and combine harvesters save time and money in the long run. 2. Increased use of Chemicals Farmers have become more reliant on the use of chemical fertiliser and pesticides to improve the quality and quantity of their farm produce. 3. Increased Field Size The steady increase in the use and size of machines has brought with it a need for bigger fields so the machines can be used more efficiently. 4. Changes in land use Farmers now use their land in different ways. For example, the EU has encouraged farmers to grow crops such as oilseed rape in place of barley or oats. Environmental and Social Impacts of the CAP Loss of hedgerows and therefore a reduction in biodiversity Pollution from pesticides and fertilisers Soil erosion Increased mechanisation led to rural unemployment o People moved away from the area - rural depopulation o Local services like schools had to close Because of these problems the CAP was reformed in 1992 to incorporate the following changes. Quotas: In 1992 the Common Agricultural Policy was reformed and one of the main things that was brought in was quotas. These set a limit on how much one farmer could produce of a single product. Set aside land: To reduce overproduction, farmers are now offered grants to not grow crops on up to 20% of their land. Diversification: Due to the reform of the CAP, farmers have seen a rapid decline in their income. Many have had to diversify and seek income from other sources. Some have moved into the leisure industry and provide accommodation and facilities for visitors. 5

6 Recent issues in farming: Animal welfare: to increase yields, a factory farming approach has been adopted by many pastoral farmers. This has led to controversy over animal welfare. Organic farming: as the public has become more aware of the use of chemicals in modern farming techniques, there has been an increased demand for more organic produce. Genetically modified crops: although not currently legal in the UK, many countries around the world now use GM crops to increase yield. This has led to a number of social and environmental problems. Question 3 Look at the diagram above. Since 1945, 25% of UK hedgerows have been removed from farmland. Describe the advantages and disadvantages of this change. 4 marks Question 4 Look at the diagrams on the next page. The changes in farming since 1950 have brought more benefits than problems.

9 Farming Change in Developing Countries Case Study: India What is intensive peasant farming? Farming Landscape very small farms small narrow fields in strips, separated by bunds (earth embankments) fragmented farms (farmer s land in separate strips, spread over wide area) irrigation channels leading from well, river or small reservoir terraced hillsides Farming Methods mostly arable farming rice is the most important crop, grown in the wet season. land is continually cultivated. Two or three crops per year may be harvested. soil is kept fertile by: - ploughing in stubble, - relying on silt from annual floods - manuring using natural materials rice is grown initially in nurseries and then transplanted into padi fields to trap water from the river. The Green Revolution This agricultural system has been most affected by the Green Revolution. This Green Revolution is the huge increase in world food production in recent years, by the use of modern techniques. The most important changes have been: 1. improved varieties of seeds (hybrid crops) 2. increased use of fertilisers and pesticides 3. increased irrigation 4. increased mechanisation 5. improved infrastructure e.g. roads, electricity Impact of Green Revolution Hybrid Crops Advantages Increased yields More food to eat and sell Improved standard of living Disadvantages Hybrid crops only grow well with lots of chemicals Poorer farmers cannot afford to grow them Wealth gap grows More harvests per year 9

10 Increased Irrigation and Mechanisation Advantages Can farm larger areas More harvests per year Greater increase in food production Disadvantages Mechanisation means fewer workers needed e.g. landless labourers, even surplus family members Greater unemployment Greater emigration to cities Greater problems in cities The Impact of Biofuels Demand for food crops continues to increase but world prices fluctuate as farmers have good years and bad years. Some farmers have turned to new crops in order to seek out new markets or better prices for the crops that they grow. A good example of this has been the growing of crops for the production of biofuels. There have been two consequences of this change in land use: 1. Worldwide, less land is being used to produce food at a time when the world population continues to grow. 2. As demand and prices have risen for crops such as palm oil, new land has been cleared to start plantations. The land that is being cleared in countries such as Indonesia and Malaysia is often rainforest or other precious environments where plant and animal diversity is high and indigenous people live traditional lives in harmony with the delicate ecosystems. Countries like the UK cause the demand for palm oil and other biofuels. As a country and as individuals, we have a responsibility to ensure that the products we use are produced sustainably wherever possible. Governments in less economically developed countries face a dilemma when trying to choose between protecting the environment and boosting the economy, as strengthened economies can act as a catalyst for rural development and political stability. Profits from biofuel plantations can also be used for social initiatives to alleviate poverty and the palm oil industry provides jobs for people who have few other opportunities. Large, western multinationals with a vested interest in producing more of these industrial products are often involved in investing and supporting these large scale developments. 10
