In the UK, agriculture occupies about 25% of the country's total land area and accounts for 1.5% of the country's labor force that is equivalent to 476,000 people while contributing about 0.62% of the country's GDP. The country produces less than 60% of the food it consumes, and most of the agricultural activities are carried out rural locations particularly in East Anglia where crops are predominant, while South Wales is popular for livestock keeping. The UK has some of the highly skilled farmers, highly fertile soils and employs high technology, while the government gives subsidies to farmers, but the earnings are still relatively low as a result of low prices of farm outputs. As a result, the young generation in the UK is discouraged from engaging in agricultural activities, and the average age of a British farmer is about 59 years. The total area under agriculture in the UK is about 9.34 million hectares, and about one third is arable, and the rest are grasslands. About half of the arable land in the country is devoted to cereal crops, and the widely cultivated cereal crop is wheat. Farming in the UK is intensive and highly mechanized, and in 2010 the country exported agricultural products valued at £14 billion and imported about £32.5 billion worth of agricultural products.
The climate in the UK, which is characterized by mild winters and heavy precipitation coupled with fertile soils and hilly sheltered topography is ideal for tree growing. The broad-leaved hardwood trees are found in the UK exceeds those found in any other place in Europe, while other trees like conifers which are softwood have growth rates which three times faster than those in Sweden and five times faster than those in Finland. Approximately 12.9% of the land area in the UK is covered with trees. During the first and second world wars, the country’s supply of timber severely affected the wooded areas. By 1919 the area that was forested in the UK was below 5% compared to other countries in Europe which had an average of between 25% and 72%. It was during this time that the Forestry Commission was established in the UK to provide a strategic reserve of timber. Currently, about 12,120 square miles of the land area is forested in the UK, and about 30% of these are publicly owned, and the rest are privately owned. In 2010 the government of the UK suggested that it might sell about half of it is woodland areas owned by the Forestry Commission.

The coastal resorts such as Lancashire, Blackpool, Wales, and Swansea have had a long history of family visits and bookings in holiday camps.
