Agriculture Ham was an agricultural community for centuries, with meadow and pasture land mostly along the river, and common grazing. The tithe map of 1842 showed a total area of , but when adjusted for the land in Richmond Park, were
arable, meadow or pasture, was common land, and only woodland. The crops were mainly wheat, barley and oats. with some
flax, potatoes, turnips and
mangel wurzels. Livestock included cows, sheep, pigs, goats, ducks and chickens as well as horses and donkeys – many of which grazed the common land. Ham had three farms at the time, all on land owned by the Earl of Dysart. Unusually, these remained very little
enclosed and the
open field system survived in use until the late 19th century. Improvement in transport and the growth of London led to a shift from general mixed agriculture to market gardening by the early 20th century. Ultimately, the same growth fuelled demand for housing land, and this factor along with the greater profitability of gravel extraction on land that could not be used for housing, meant that agriculture in Ham had ceased by the mid-1950s.

William Tollemache, 9th Earl of Dysart leased part of the farmland to the Ham River Grit Company Ltd to extract sand and
ballast. A dock was constructed in 1913 and a lock in 1921, parts of which remain as the
Thames Young Mariners water activity centre. A
narrow-gauge railway linked the site to the main road. During the
Second World War the flooded pits were reputed to have been used to store sections of the
Mulberry harbour. After the war, most of the pits were filled with bomb-damage rubble from London. The pits operated until 1952, after which some of the land was used for subsequent housing development, the
Wates estate. Local resistance to further development led to the area being designated
Metropolitan Open Land, preserving Ham Riverside Lands as a nature reserve. It has notably unusual vegetation due to the underlying alkaline rubble instead of the more acidic fluvial deposits.
Engineering |alt=Sopwith Dolphin biplane Towards the end of
World War I, Lord Dysart sold some land south of Ham Common to the
Ministry of Munitions for the construction of an aircraft factory on land adjoining what was then still called Upper Ham Road.
National Aircraft Factory No. 2 was built in 26 weeks during the winter of 1917. The factory was leased to the
Sopwith Aviation Company, based a mile to the south in Canbury Park Road, Kingston, and the company were able to increase greatly its production of
Snipe,
Dolphin and
Salamander fighter planes as a result. At the end of the war, demand ceased. Sopwith tried to buy the factory outright but the government refused. Sopwith Aviation went into voluntary liquidation and reformed in 1920 as H. G. Hawker Engineering at their original Kingston base. The remaining Ham Factory lease was sold to
Leyland Motors, which initially used it to recondition ex-War Department lorries for civilian use. It was then used to produce under licence the
Trojan Utility Car between 1922 and 1928. During the 1930s, the factory produced
Leyland Cub trucks. World War II shifted production to military vehicles, fire engines, other equipment and munitions. After the war the site produced the chassis for Leyland's
trolleybus. In 1948 the site was sold back to
Hawker Aircraft Ltd and it became the main base for Kingston's aviation industry. The
Hawker Hunter was produced there in large numbers, driven by
Cold War demand. The profits allowed the site to be redeveloped as Hawker's UK headquarters and the factory gained an imposing frontage by 1958 in a building that closely linked design and production. The company became part of
Pinchin Johnson and was acquired by
Courtaulds in 1960, continuing under the
International Paint group banner from 1968. The factory closed in the 1980s and the site was redeveloped as a small industrial estate.
Today Apart from one
plant nursery, local community, retail and small scale offices, Ham today is predominately a commuter residential area dependent on employment outside the immediate area. ==Landmarks==
