New, global initiatives to restore forest landscapes present an unparalleled opportunity to reverse deforestation and forest degradation. Participatory monitoring could play a crucial role in providing accountability, generating local buy in, and catalyzing learning in monitoring systems that need scalability and adaptability to a range of local sites. We synthesized current knowledge from literature searches and interviews to provide lessons for the development of a scalable, multisite participatory monitoring system. Studies show that local people can collect accurate data on forest change, drivers of change, threats to reforestation, and biophysical and socioeconomic impacts that remote sensing cannot. They can do this at one-third the cost of professionals. Successful participatory monitoring systems collect information on a few simple indicators, respond to local priorities, provide appropriate incentives for participation, catalyze learning and decision making based on frequent analyses and multilevel interactions with other stakeholders. Participatory monitoring could provide a framework for linking global, national, and local needs, aspirations, and capacities for forest restoration. Article impact statement: Participatory monitoring could be the key to linking the needs of local people and global conservation. This article is protected by copyright. All rights reserved

Monitoring is crucial to meet the goals of the major global forest landscape restoration (FLR) initiatives that are underway. If members of the global FLR community are going to learn from one another, a multi‐scalar, multi‐site monitoring approach is needed to generate information that can provide the basis for social learning and adaptive management, both of which are essential processes for FLR. This requires reframing and expanding the perspective of monitoring so that compliance monitoring is just one component of a multidimensional approach where collaborative monitoring and compliance‐oriented monitoring are complementary. However, FLR planners and implementers often lack experience in applying collaborative approaches in multi‐stakeholder settings, and there are few tools that show how to implement FLR or to engage in collaborative monitoring in FLR. Through a literature review, we identified the factors that contribute to successful collaborative monitoring in FLR and synthesized them into a diagnostic that was vetted by 20 global experts. The result is a checklist of 42 core success factors to be assessed at local, subnational, and national levels at different stages in the planning and implementation of FLR. The tool has practical application by providing guidance on best practices: specifically, how to start collaborative monitoring, and more generally, how to plan, prepare for, and evaluate FLR activities. This diagnostic complements other diagnostics, such as those used to identify FLR sites, as it can identify preexisting strengths and weaknesses in new initiatives, or pinpoint problems with ongoing implementation. The diagnostic explicitly addresses issues of scale, including multiple sites, governance levels, and changes over time.

From 2016–2019, the West African Forest-Farm Interface (WAFFI) project engaged with smallholder farmers in northern Ghana to explore mechanisms to improve the influence of under-represented peoples, particularly women, in decision-making processes and platforms that affect their access to natural resources. Through a multi-phase process of participatory activities, including auto-appraisal, participatory action research (PAR) and facilitated knowledge exchange, villagers and researchers worked together to document and develop a better understanding of the challenges and changes facing women and men in the region to generate social learning. Among these challenges, the degradation of forest resources due to over exploitation, weak governance and conflict of use over shea trees (Vitellaria paradoxa) were particularly important for women. The WAFFI approach created a scaffold for social learning that strengthened the capacity of local stakeholders to share their perspectives and opinions more effectively in multi-stakeholder forums and dialogue related to resource use and land use change initiatives.
