Rapid development of science and technology caused humans to live fast and accordingly that reality brought together the pollution problem. Increase in population and misuse/overuse of resources led to huge waste amounts. The world's population of 1.5 billion at the beginning of the century turned out to be over 3 billion in the mid-century that caused the full use of resources. That fact, forced the humans to search for new ways in development and planning. LUCIS (Land Use Conflict Identification Strategy) model has been used to identify most suitable lands for conservation especially in developing countries to find probable solutions against land-use conflicts. The model enables new tools for land-use suitability analysis and produces a spatial representation of probable conflicts of future land use distribution. Through this model, strategies and targets are created, best suitable conservation areas are determined in terms of physical and economic aspects, and the results achieved are compared with currently existing conservation areas. According to the results of this study; natural resources, water basins, forests together with green areas and parks in the city has been under urbanization pressure in Istanbul. Accordingly, the outcomes point out that development plans should give priority on the environmental and natural resource protection. Moreover, model for future land conservation areas are produced with LUCIS regarding environmental and natural resource protection.
