The most important farm crops are wheat, barley, oats, sugar beets, potatoes, and rapeseed. While significant proportions of wheat, barley, and rapeseed provide animal feed, much of the remainder is processed for human consumption through flour milling (wheat), malting and distilling (barley), and the production of vegetable oil (rapeseed). The main livestock products derive from cattle and calves, sheep and lambs, pigs, and poultry. The United Kingdom has achieved a high level of self-sufficiency in the main agricultural products except for sugar and cheese.

Forestry
About one-tenth of the United Kingdom’s land area is devoted to productive forestry. The government-supported Forestry Commission manages almost half of these woodlands, and the rest are in private hands. Domestic timber production supplies less than one-fifth of the United Kingdom’s demand. The majority of new plantings are of conifers in upland areas, but the commission encourages planting broad-leaved trees where appropriate. Fishing
Although the United Kingdom is one of Europe’s leading fishing countries, the industry has been in long-term decline. Fishing limits were extended to 200 nautical miles (370 km) offshore in the mid-1970s, and, because a significant part of the area fished by other EU members lies within British waters, it has been necessary to regulate catches on a community-wide basis. Meanwhile, the United Kingdom has lost opportunities to fish in some more-distant waters (e.g., those off Iceland), and this has reduced its total catch more than those of other countries of the EU. The United Kingdom’s fishing industry now supplies only half the country’s total demand. The most important fish landed are cod, haddock, mackerel, whiting, and plaice, as well as shellfish, including Nephrops (Norway lobsters), lobsters, crabs, and oysters. Estuarine fish farming—mainly of trout and salmon—has expanded considerably. Resources and power Minerals
The United Kingdom has relatively limited supplies of economically valuable mineral resources. The once-important extraction of iron ore has dwindled to almost nothing. Other important metals that are mined include tin, which supplies about half the domestic demand, and zinc. There are adequate supplies of nonmetallic minerals, including sand and gravel, limestone, dolomite, chalk, slate, barite, talc, clay and clay shale, kaolin (china clay), ball clay, fuller’s earth, celestine, and gypsum. Sand, gravel, limestone, and other crushed rocks are quarried for use in construction. Energy
By contrast, the United Kingdom has larger energy resources—including oil, natural gas, and coal—than any other EU member. Coal, the fuel once vital to the British economy, has continued to decrease in importance. Compared with its peak year of 1913, when more than one million workers produced more than 300 million tons, current output has fallen by more than four-fifths, with an even greater reduction in the labour force. Power stations are the major customers for coal, but, with growth in the use of other fuels and the increasing closing of pits that have become uneconomical to operate, the industry remains under considerable pressure.
The discovery of oil in the North Sea and the apportionment of its area to surrounding countries led to the rapid development of oil exploitation. Since the start of production in 1975, the quantities brought ashore have grown each year, and the United Kingdom has become virtually self-sufficient in oil and even an exporter. With an average output of nearly three million barrels per day at the beginning of the 21st century, the country was one of the world’s largest producers. The balance of payments has benefited considerably from oil revenues, and a substantial proportion has been invested abroad to offset diminishing oil income in the future. Proven reserves were estimated at around 700 million tons in the late 1990s.
Since offshore natural gas supplies from the North Sea began to be available in quantity in 1967, they have replaced the previously coal-based supplies of town gas. A national network of distribution pipelines has been created. Proven reserves of natural gas were estimated at 26.8 trillion cubic feet (760 billion cubic metres) in the late 1990s.
Self-sufficiency in oil and natural gas and the decline of coal mining has transformed Britain’s energy sector. Nuclear fuel has slightly expanded its contribution to electricity generation, and hydroelectric power contributes a small proportion (mainly in Scotland), but conventional steam power stations provide most of the country’s electricity. Manufacturing
The manufacturing sector as a whole has continued to shrink both in employment and in its contribution (now around one-fifth) to the GDP. The decline in manufacturing largely accounted for the rapid rise in unemployment in the early 1980s. Once economic growth returned, however, there was great improvement in productivity and profits in British manufacturing.
In terms of their relative importance to the GDP, the most important manufacturing industries are engineering; food, beverages (including alcoholic beverages), and tobacco; chemicals; paper, printing, and publishing; metals and minerals; and textiles, clothing, footwear, and leather. The fastest-growing sectors have been chemicals and electrical engineering. Within the chemical industry, pharmaceuticals and specialty products have shown the largest increases. Within the engineering industry, electrical and instrument engineering and transport engineering—including motor vehicles and aerospace equipment—have grown faster than mechanical engineering and metal goods, and electronic products have shown the fastest growth. On the other hand, the growth in motor vehicle production has occurred among foreign-owned, especially Japanese, companies investing in the United Kingdom. British automobile manufacturers have been in decline since the 1970s. After a period of restructuring during the 1980s, the British steel industry substantially increased its productivity, output, and exports during the 1990s. However, food, beverages, tobacco, leather, and engineering as a whole have had below-average growth. Textiles, clothing, and footwear have been in absolute decline because British companies have faced increasing difficulty competing with imports, especially from Asia.
During the 1980s imports of manufactured products increased dramatically, and, although exports of finished manufactured products increased in value, the surplus in the balance of trade disappeared and was transformed into a large deficit. Nevertheless, after a period of restructuring in the 1980s, Britain’s manufacturing sector increased its productivity and competitiveness, and the trade balance improved and stabilized during the 1990s.
Construction in Britain stagnated during the 1990s because of a decline in prices and in demand for new housing and because of decreased government investment in infrastructure during the first half of the decade. About half the labour force in construction is self-employed. More than half of all construction work is on new projects, the remainder on repair and maintenance. There has been a marked switch from housing funded and owned by public authorities toward private development. Considerable efforts have also been made to encourage tenants of publicly owned rented houses to become owner-occupiers, with the result that the proportion of owner-occupied homes has grown considerably since the early 1970s. The supply of privately rented accommodations became scarcer because of statutory rent controls that discouraged new construction, but changes during the 1980s both in the economic climate and in official policy began to stimulate the supply. The average price of a new house, particularly in London and the South East, has generally continued to increase more rapidly than the prevailing rate of inflation, although prices have fluctuated considerably. In turn, the rising price of new homes has created considerable pressure on the land available for housing, which has been relatively tightly controlled. Here, too, public policy has been changing in favour of greater permissiveness.
