There are a number of important interactions of the energy, economy and climate systems represented in REMIND with the land system, such as emissions from land use changes and agriculture, or bioenergy supply. In the default standalone mode, REMIND relies on reduced-form approaches to account for these inter-linkages between the energy and the agricultural and land-use sectors (stand-alone mode). These are derived based on the state-of-the-art land use model MAgPIE ; ; . For a detailed and fully consistent analysis of the integrated energy-economy-land use system, REMIND can also be soft-linked and run iteratively with MAgPIE as depicted in Figure 7 (coupled mode). The soft-link between REMIND and MAgPIE focuses on two crucial interactions: (i) bioenergy demand and supply, (ii) land use/land use change emissions and GHG prices. At the end-point of the iterative solution process, the markets for bioenergy and emission mitigation across the energy and land-use sector are in equilibrium.
Figure 1. In the coupled mode REMIND is soft-linked to the land-use model MAgPIE. The models are run iteratively and exchange information about bioenergy demand and supply and about emission mitigation in the land-use system.
