The purpose of the present PhD project was to identify the mechanisms governing global land use
consequences of increased crop demand in a given location and, based on this conceptual analysis,
to present and demonstrate a method proposal for construction of land use data that can be used in
life cycle assessments involving crop consumption.
Increased demand for a given crop can be met by intensification, expansion, and/or by displacement
of other crops or pastures. The last option will reduce the supply of other agricultural products,
which may then be replaced elsewhere. Such displacement-replacement mechanisms are governed
by the availability of suitable agricultural land and several economic conditions, such as transport and
trade costs. To estimate the land use response to an increase in crop demand, economic modelling
can be used. In this project, the economic equilibrium model GTAP (Global Trade Analysis Project) was
modified and applied to simulate increased demand for wheat in respectively Brazil, China, Denmark,
and the USA. The net expansion of the global agricultural area was thereby estimated and it was
attempted to classify the affected nature types (biomes) by use of global agricultural maps and
agricultural statistics. |
