EXPLORATORY LAND-USE STUDIES AND THEIR ROLE IN STRATEGIC POLICY-MAKING

To support the different phases of a policy making process aimed at ch anging land use, distinct types of land use studies are required. This paper focuses on exploratory land use studies and their role in the p hase of formulating strategic policy objectives. Exploratory land use studies contribute to a transparent discussion on policy objectives by showing ultimate technical possibilities and consequences of imposing different priorities to agro-technical, food security, socio-economic and environmental objectives. A methodology is presented in which sci ence-driven technical information is confronted with value-driven obje ctives under given values of exogenous variables (e.g. regarding popul ation growth and requirements for agricultural produce). Land use scen arios are generated showing consequences of different priorities for o bjectives by using natural resources and technical possibilities in di fferent ways. Applications of such an approach are given for the globa l, regional and farm level, each addressing specific questions and tar get groups. The paper focuses on the type of results these studies pro duce and their role in the societal and political debate on strategic land use policy and planning. It is concluded that if exploratory land use studies are carried out in true interaction with target groups, t hey may well contribute to the debate and learning on sustainable land use options and a purposeful identification of effective policy instr uments in a next phase of the policy making process.
