The Royal Society is the national academy of science for Great Britain and Northern Ireland but, unlike other national academies, is and always has been independent of state control; it is not maintained by grants from public funds and manages its own affairs.

Within ten years of its foundation the society, at the invitation of Charles II and his ministers, grappled with problems of national food supply, arboriculture, naval architecture and navigation. Throughout the 18th century it worked with the admiralty on what was then called ?the problem of the longitude? in the solution of which are associated the names of the astronomers Edmond Halley and Nevil Maskelyne.

Erosion is regarded not merely as the physical removal of soil by water and wind, but rather as the deterioration of all the component parts of the habitat in which man and his crops and livestock have to exist. Since there is no conclusive evidence for any major climatic change in historic times to explain this deterioration, we must conclude that the eroding of the total environment has been due primarily to thoughtless destruction of the vegetative cover. This has led to deterioration of the microclirnate above and below the surface, generally in the direction of a general drying out of the soil which has exposed it to erosive action of wind and rainfall of high intensity or frequency, and to the loss of organic matter in the soil, thus reducing its capacity to resist erosion by conserving the water that falls on the surface. If everything possible is done within the total environment to conserve the naturally planted or cultivated vegetation, this will also ensure optimal conservation of soil and water.
