World - Grid Type, Continuously Under-development - System Dynamics The main goal of United Nation is realization of sustainable development world society vision. Such society need to integrate social development with economic development and environmental protection. For this end it is necessary to enable sustained economic growth, internalizing externalities and decoupling the range of economic growth from the range of deficit natural resources depletion growth and degradation of environment. In order to achieve above UN Goal we have to build WORLDWIDE, COMMONLY ACCESSIBLE, SUSTAINABLE DEVELOPMENT-INFORMATION SYSTEM for: - comprehensive monitoring, - far-sighted forecasting, and - measurable evaluation, of policy, economy, work, and other changes effects in life-conditions of human-beings and nature in general. This system ought to be built on the base of System Dynamics. We propose research program, which allows to describe conditions of creation such big, grid type, multi stage built, information system.
