Extending water resources
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there are areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enough water to support the current population adequately. Decisions will have to be made on the best way to use water in a worl

Having got the draft plan, it is worth checking it over to see that all the major issues have been covered. The appendix below contains a set of guidelines for the initial audit of a generic ‘general purpose’ plan. For site-specific plans such as might be produced by an SHE manager in industry, or a business continuity manager for an office complex, the headings may need some modification.

A plan which supports the emergency management team by providing them with information and guidelines.

James Clerk Maxwell produced a unified theory of the electromagnetic field and used it to show that light is a type of electromagnetic wave. This prediction dates from the early 1860s when Maxwell was at King's College, London. Shortly afterwards Maxwell decided to retire to his family estate in Galloway in order to concentrate on research, unhindered by other duties.

This course presents Maxwell's greatest triumph – the prediction that electromagnetic waves can propagate vast distanc
