Abstract
The maps and analysis by Strassburg et al.1 should not be used by
policy-makers in their current form, because of the risk of displacing
marginalized people, compromising food security and undermining
democratic processes. Their analysis was based on normative choices to
value (that is, to optimize) relationships among biodiversity potential,
carbon storage potential and cost-effectiveness, without considering
the well-being and rights of people who live in areas identified as
restoration priorities, nor the implementation costs of changing land
use. Although it may be informative to map the joint distribution of
biodiversity, carbon and commodity prices, the absence of important
socioeconomic values obscures both the costs and benefits to
the Indigenous, forest-dependent and rural people who are directly
affected by restoration interventions. We pose three cautionary questions
that we believe must be answered before the maps produced by
Strassburg et al. are used by decision-makers to motivate and implement
restoration-promoting land-use policies.
