Climate Change : A New Challenge for Land Resource Allocation

While the global demand for land-based products is increasing, climate change is projected to negatively affect the land productivity in many regions by 2050. Land allocation might become a central issue for ensuring food safety and human resilience. In this context, the scientific literature on agricultural adaptation, land use change and climate-induced land needs and losses suggests that the land market, as a resource allocation mechanism, may be affected. I formalize the climate change - land market nexus (CC-LM nexus) and conduct a selected review of how economic models tackle this issue. Regarding methodological issues, results show that models use various methods to address micro and macro levels, spatial and time dimensions, dynamics and uncertainties. Also, approaches differ in their grasp of the CC-LM nexus, through the climate or land market characteristics they address, and the way they assume interactions between both. The modelling of climate change impacts mainly refers to land conditions, e.g. land state, use or cover change. The land market is usually addressed in rather segmented views: models focus either on land demand, land value or transaction mechanisms. Finally, the CC-LM nexus becomes a research object in its own right, which calls for a renewed research agenda
