N and H is conditional and can be interpreted as the division of all natural processes
into controlled and non-controlled. As world population increases, natural catas-
trophes will intensify the sensation of unconformity re
fl
ected in the social and
cultural conditions of many regions.
From the viewpoint of the theory of systems, H and N are open systems. Without
going into philosophical and methodical aspects of this division, we assume that
systems are symmetrical from the viewpoint of their simulation. In addition, the
system H disposes technology, science, economic potential, industry and agriculture,
sociological structure, size of the population, etc. The process of the interaction
between the systems N and H brings about a change of

compare advantages and danger, to understand the principal restrictions of our
possibilities and to realize the new threats in good time.
As a result of the many aspects of the environmental change in recent decades,
many authors have come up with multiple concepts to describe the NSS on a global
basis and models of different complexity to parameterize the dynamics of biospheric
characteristics. The presence of the global database containing various information
characteristics allows to consider and to evaluate the consequences of a possible
realization of the different scenarios of the subsystem H development. Traditional
approaches to synthesizing global models are founded on considering collections of
balance equations, in which parameters {xi}

} take the form of functions, arguments,
factors, and conditions of the transition between parametric descriptions of envi-
ronmental processes. Moreover, other approaches based on evolutionary and neural
network algorithms have been used (Nitu et al. 2004). The organization of the N

global model functioning can be presented in the manner of a conceptual scheme
