Management of natural resources and environment are things that contain a lot of challenges.This includes land resources, water, air, vegetation, and energy very owe influence of human activities and attitudes. A fundamental problem is that each component of the interconnected environment and can generate events that are not desired. For example, river water pollution associated with wastewater output related to various factors, such as sources of waste, waste characteristics, accumulated waste, waste handling process, method and location of disposal, transportation of waste in river flow, and the influence of waste on aquatic biota, and water use by human.
In general, each component can be analyzed separately, but the actual river water pollution problems are the result of interaction and collective influence of a system of wastewater pollution.
Environmental problems, if examined in the system will provide many uses.Problematic can be calculated by the totality of which the most effective control work can be found. In the example of pollution of the river waters, a systems approach will be able to produce a combination of source reduction of waste, methods of handling, and disposal sites more effective and allow lower costs through improved handling of it. A consequence of the systems perspective on environmental quality is likely to widen the application of alternative control strategies and opportunities for efficient and integrated managerial
