Environmental management is concerned with taking charge and controlling the biological and physical elements of our surroundings including land, air, water, plants and animals. Environmental management has been defined as a multi-layered process associated with the interactions of state and non-state environmental managers with the environment and with each other. Environmental managers are those whose livelihoods are primarily dependent on the application of skill in the active and self-conscious direct or indirect, manipulation of the environment with the aim of enhancing predictability in a context of social and environmental uncertainty. Undertaking environmental management can bring about higher standards of safety and security (e.g. by addressing global warming as a cause for environmental disasters) and benefits to the lifestyle of people (e.g. by protecting the quality of water resources in order to preserve fish stocks as a source of food). The reduction of costs by improving environmental performances (optimising process efficiency minimises the use of raw materials and energy and the amount of waste production) and the minimisation of environmental risks are considered to be further advantages of environmental management. In the absence of environmental management, people will be more vulnerable to natural disasters and development is unlikely to be sustainable. One main objective of environmental management is thus to work towards ecologically sustainable development.
