  1. Abstract Tropical forests are increasingly threatened by deforestation and degradation, impacting carbon storage, climate regulations and biodiversity. Restoring these ecosystems is crucial for environmental sustainability, yet monitoring these efforts poses significant challenges. Secondary forests are in a constant state of flux, with growth depending on multiple factors.Remote sensing technologies offer cost‐effective, scalable and transferable solutions, advancing forest restoration monitoring towards more accurate, efficient and real‐time data analysis and interpretation. This review provides a comprehensive evaluation of the current state and advancements in remote sensing technologies applied to monitoring tropical forest restoration.Synthesis and applications: This review brings together the state of the art of remote sensing technologies, such as very‐high‐resolution RGB imagery, multi‐ and hyperspectral imaging, lidar, radar and thermal‐infrared technologies and their applicability in monitoring forest restoration. In conclusion, this review emphasizes the potential of remote sensing technologies, coupled with advanced computational techniques, to enhance global efforts towards effective and sustainable forest restoration monitoring.

    We present the results of a hybrid research design that borrows from both experimental techniques—experimental games—and observational techniques—surveys—to examine the relationships between basic human values and exposure to natural ecosystems, on the one hand, and collective action for resource governance, on the other. We initially hypothesize that more frequent exposure to forests, and more pro-environmental values will be associated with more conservation action. However, we find that other values—tradition and conformity—are more important than pro-environmental values or exposure to nature. Our results imply that resource governance is likely to be more successful where resource users hold values that facilitate cooperation, not necessarily strong pro-environmental values.

  3. The Amazon has a diverse array of social and environmental initiatives that adopt forest-based land-use practices to promote rural development and support local livelihoods. However, they are often insufficiently recognized as transformative pathways to sustainability and the factors that explain their success remain understudied. To address this gap, this paper proposes that local initiatives that pursue three particular pathways are more likely to generate improvements in social-ecological outcomes: (1) maintaining close connections with local grassroots, (2) pursuing diversity in productive activities performed and partnership choices, and (3) developing cross-scale collaborations. To test these ideas we collected and analyzed observations of 157 initiatives in Brazil and Peru, applying a combination of quantitative and qualitative analyses. Our results show that initiatives maintaining groundedness in representing the interests and concerns of local actors while partnering with other organizations at multiple scales are more likely to develop joint solutions to social-ecological problems. Partnerships and support from external organizations may strengthen and enhance local capabilities, providing a platform for negotiating interests and finding common ground. Such diversified pathways demonstrate the power of local actors to transcend their own territories and have broader impacts in sustainability objectives. Our findings highlight the need to make governmental and non-governmental support (e.g., financial, technical, political) available according to local needs to enable local initiatives’ own ways of addressing global environmental change.
