“…Communally owned forests, such as those legally owned by Indigenous people and communities, represent 28% of the world's forestlands (Gilmour 2016). In Mexico, over half (53.4%) of the total land in the country is under a communal-based ejido system (Morett-Sánchez et al 2017) where ejidos and indigenous communities 5 hold about 60% of the country's forestlands (Bray et al 2003, Torres-Rojo et al 2022. This makes Mexico the second largest holder of communal forests in the world, after Papua New Guinea (Barnes 2009).…”

More than half of Mexico’s forests and about a third of the forests of the world are communally-owned. Despite this, community forest management (CFM) is the least studied forest management policy, and existing studies have focused on the effects of CFM on deforestation. In this paper, we evaluate the effect of CFM on land cover more broadly, to understand how CFM affects a community’s land use decisions. . Mexico’s forestry administration mandates that to legally sell timber, communities must adopt forest management plans designed by a certified forester. In this study, we use differential access to foresters to identify the effect of community management on land cover and deforestation. We find that over time communities that adopt management plans see relatively more primary forest, a limited expansion of the agricultural frontier, and a decrease in deforestation. The decrease in deforestation is economically significant since the economic benefits from the avoided CO2 emissions alone could far outweigh the costs of adopting the management plans.

“…We therefore consider it of utmost importance to develop an innovative methodology for the assessment of the forest component survival of the Sembrando Vida program using low-cost civilian-use drones [24] that are accessible to forest communities [25]. This could eventually allow for the rapid and large-scale assessment of the survival of the seedlings established in Sembrando Vida plots, possibly reducing the costs in effort and time compared to traditional field-assessment techniques [26,27].…”

Reforestation is one of the main actions undertaken to mitigate the effects of climate change. In Mexico, the Federal Government program “Sembrando Vida” (Sowing Life) is currently the most important reforestation effort. It aims to recoup forest cover and achieve food self-sufficiency through the establishment of agroforestry systems. The evaluation of tree survival in reforested areas helps to identify achievements and failures, as well as aspects of the program that require improvement. However, given the magnitude of this program, evaluation using traditional methodologies is labor-intensive and costly. In this context, drones equipped with high-resolution cameras are a promising tool. The objective of this study was to evaluate the feasibility of using drones to monitor tree survival in reforested areas. This study was conducted in 12 randomly chosen plots, benefited by the “Sembrando Vida” program, located on the Purépecha Plateau in the state of Michoacán, in central–western Mexico. Field surveys with GPS were conducted to record the total number of live and dead forest-tree seedlings. Simultaneously, high-resolution images were captured using a DJI Phantom 4 Pro drone equipped with an RGB camera for subsequent visual interpretation in a geographic information system to determine the status of each seedling and calculate the rates of survival. ANOVA was performed to compare the survival calculated using the drone images compared to that recorded in the field. No significant difference was found between survival estimated using the drone and that recorded directly in the field in any of the study plots, although the drone overestimated survival by an average of 6%, mostly due to the presence of dead seedlings that had already lost their foliage and were thus missed when scoring the RGB image. It is therefore concluded that the estimation of survival using drones is a reliable method. For future research, it is recommended to evaluate machine-learning algorithms in terms of detecting both living and dead trees in reforested sites. It is also recommended to use multispectral thermal cameras and LiDAR technology to broaden the knowledge of the different levels of vigor/stress present in the vegetation.
