Description

Nowadays, production of food, energy and materials, and the related use of land and water account for crucial components and interactions in the Earth System. Increasing demand for agricultural and forest products due to future population growth and economic development but also climate change and ambitious mitigation policies such as bioenergy and avoided deforestation will add additional pressure on the land system.

The landuse management group of Research Domain III aims at assessing future sustainable pathways for the landuse sector (together with colleagues from RDI).

 

The focus lies on:

  1. The potentials, limits of global bioenergy production but also its trade-offs with other sustainability goals such as food security and biodiversity conservation.
  2. Impacts and damages of climate change on the agricultural and forestry sector
  3. The importance of forest conservation for climate change mitigation
  4. The role of technological change in competing uses of land and water for food production, energy production, forestry and biodiversity conservation
  5. The importance of economic development, population growth, food demand patterns and habits, trade and agricultural production technologies for global land use patterns and land-use related emissions

 

Tools

Major tool and product of the group’s activities is MAgPIE, a global land and water use model. MAgPIE in connection with the dynamic global vegetation and hydrology model LPJmL provides a consistent link between economic development, food and energy demand in different world regions with spatially explicit patterns of production, land use change and water constraints. To assess macroeconomic, energy and climate policy feedbacks MAgPIE is linked to the ReMIND model that embeds a detailed energy system within a macro-economic intertemporal growth model and a climate system model that computes the effect of GHG emissions on global mean temperature.
