Abstract
Land use study is one of the important field in understanding, systematizing and laying the foundation of the ‘environment as a system’ in relation to human beings and their society. Also it is the subject of social environmental engineering that encompasses both natural and social scientific aspects.
LU/GEC (Land Use for Global Environmental Conservation) Project of NIES aimed at constructing land use prediction models for Asia-Pacific region. This article presents Indonesian results especially Jawa results using the following two principal models.
CEDEq-LU (Constant Elasticity Dynamic Equilibrium of Land Use) Model'(Sunsun 1998) can predict the future change of supply-demand relationships of land market by solving the equilibrium equations that are composed of both supply functions with land use area and land use productivity variables and demand functions with basic demand and correction factor valuables.
GT (Generalized ThÜnen) Model'(1997 a, c, 1998, Konagaya 1997a, 1998 a, b) is the extension of traditional normative ThÜnen model, the exact fundamental theory of land market, to be able to explain the real land use ratio data. This new model successfully give a exact theoretical interpretation to the intuitive picture of movement of land use frontier' such as deforestation or desertification, and enables us to predict the land use change in the future. This model tells us the realization of the land use with strong rent-bidding power.
Both models interpret urbanization processes driven by globalization as the prime factor producing land use changes. Thus, one of the environmental implication of land use is how to reconcile both globalization and sustainability: the search for land use activities with low environmental impact and high rent-bidding ability.
