World Garden - Kew
The Botanical Gardens at Kew
'A picture of springtime in Kew Gardens, of daffodils, bluebells, cherry blossom, of those exotic flowers from the tropics, the Andes, the Himalayas. In these lovely surroundings, Londoners find peace and serenity, while their children play. Rare plants are classified in the Herbarium; crop growers throughout the world are aided in their battle against pests and disease by Kew research.'

The Green Girdle

In a bid to encourage city-dwellers to leave behind the restrictions of war, 'The Green Girdle' escapes from the austere urban landscape of inner-city London and savours the natural delights of the capital’s rural surroundings.

Keyline design is a technique for maximizing beneficial use of water resources of a piece of land. The Keyline refers to a specific topographic feature linked to water flow. Beyond that however, Keyline can be seen as a collection of design principles, techniques and systems for development of rural and urban landscapes.

In a smooth grassy valley, a location called the keypoint can be found where the lower and flatter portion of a primary valley floor suddenly steepens. The keyline of this primary valley is revealed by pegging a contour line through the keypoint, within the valley shape. All the points on the line are at the same elevation as the keypoint. Contour plowing parallel to the Keyline, both above and below will automatically become "off-contour" but the developing pattern will tend to drift rainwater runoff away from the valley centre and incidentally, prevent erosion.

Keyline pattern cultivation on ridge shapes is done parallel to any suitable contour but only working on the upper side of the contour guide line. This automatically develops a pattern of off-contour cultivation in which all the rip marks left in the soil will slope down towards the centre of the ridge shape. This pattern of cultivation allows more time for water to soak in. Keyline pattern cultivation also enables controlled flood irrigation of undulating land, which further assists in the fast development of deep biologically fertile soil, which results in improving soil nutrition and health.

In many countries, including Australia, it is important to get optimum absorption of rainfall and keyline cultivation does this as well as delaying the potentially damaging concentration of runoff. Yeomans' technique differs from traditional contour plowing in several important respects. Random contour plowing also becomes off contour but usually with the opposite effect on runoff water causing it to quickly shed off ridge shapes and be concentrated in valleys. The limitations of the traditional system of soil conservation, with its "safe disposal" approach to farm water was an important motivational factor in the development of the keyline system.
