3.6.2.2Biophysical feedbacks on regional climate associated with land-use changes

… biophysical feedbacks from land-use change and land management on climate, there are potential consequences for particular ecosystem services. This includes climate change -induced changes in crop yield (e.g., Schlenker and Roberts, 2009; van der Velde et al., 2012; Asseng et al., 2013, …

3.6.2.1Risks arising from land-use changes in mitigation pathways

… the Representative Concentration Pathway (RCP)2.6 scenario could be greater than that in RCP4.5 and RCP6, in which there is more climate change but less land-use change. Risks to biodiversity conservation and agricultural production are therefore projected to result from large-scale bioenergy deployment …
