In the current EIA practice, impacts on natural systems (ecological effects) are often given less attention than they deserve (Treweek, 1999). One of the key reasons is a great deal of uncertainty associated with ecological impact studies.

Of course, the notion of system survivability is more capacious and informative. By system ecology many authors mean the stability and integrity of the system in short, the system s ability to resist external forcings. In other words, survivability is measured by the tendency of the system to suppress large oscillations of its structure and elements, returning the system to its former equilibrium state. Thus, system survivability should be understood as its ability to actively resist the impact of external factors and preserve its characteristics indefinitely.

Despite this plethora of information regarding the physiological ecology of Phaeocystis, fundamental interactions between life history traits and system ecology are poorly understood. Research summarized here, and described in the various papers in this special issue, derives from a central question how do physical (light, temperature, particle distributions, hydrodynamics), chemical (nutrient resources, infochemistry,...

Logically, risk is always connected to an object or area of concern. Within RISKBASE this risk object is defined as the goods and services provided by the biophysical soil-sediment-water system (ecological system), with a specific focus on the resilience of the system. Furthermore, RISKBASE focuses on the goods and services that are directly (or immediately indirectly) affected by rivers, lakes and groundwater.

Basically, the criterion for specifying events as accidents is that the losses are so important that they need to play a central role in the design and tradeoff process. In the outer planets explorer example in chapter 7, some of the losses involve the mission goals themselves while others involve losses to other missions or a negative impact on our solar system ecology. 

On a large scale, there are biological systems, ecological systems, weather systems, solar systems, etc. Thus, a system can be viewed as an element of a larger system, and the challenge is to understand the boundary of the system, which is the focus of the development effort, and the relationships and interfaces between this system and other systems. The focus of this standard is product-oriented systems such as the automobile, the airplane, or information systems. 

A report of the National Research Council (NRC) [19] has been discussed by Hoagland [20] and criticized for neglecting ecology because degradation of the environment is one of the crucial problems of the century. One anticipated loss is that of biophilia (i.e., the love of all hfe forms). Failure to connect the dots may result in degradation of the planet s biospheric life support system. Decisions about contaminated sediments must routinely include connections to components of the larger systems (ecological and societal) of which they are a part.
