Land Use Policies for Climate Change

This workshop aims to present recent advances in the literature on the challenges of implementing land-based mitigation measures. It will focus on key issues related to land use policies for climate change, including the design and scope of financing schemes, justice and equity, and adverse consequences such as leakage, spillover, and rebound effects. Land-based mitigation measures are among the most critical options currently available for addressing climate change (IPCC, 2022). By enabling carbon dioxide removal (CDR) through restoration and conservation, these measures are particularly crucial to pathways that limit global warming to 1.5°C, where their rapid deployment within the Agriculture, Forestry, and Other Land Use (AFOLU) sector is indispensable. Between 2020 and 2050, forests and other natural ecosystems are expected to provide the largest share of the economic AFOLU mitigation potential (IPCC, 2019; Roe et al., 2021). However, realizing this potential faces substantial hurdles. In both the scientific literature and policy implementation experience, three persistent barriers have been identified as major obstacles to effective land-based mitigation: leakage, spillover, and rebound effects (Murray et al., 2004; Stevenson et al., 2013; Ingalls et al. ,2018; Meyfroidt et al., 2020).

Spillover refers to the process by which land-use changes or direct interventions in one location—such as new policies, programs, or technologies—affect land use elsewhere, often in unforeseen ways.

Leakage is a specific form of spillover caused by environmental policies (e.g. conservation or restoration) that unintentionally displace pressure to other locations, thereby reducing the net effectiveness of the intervention.

Rebound effects occur when efficiency gains in resource use lead to increased overall demand or use, diminishing the expected environmental benefits.
