“…In our study area, where the vast majority of the land is privately owned, cadastral data represent differences in land management history with far‐reaching consequences for ecological processes (Caughlin et al, 2016; Valencia Mestre, 2017). This spatial variability could result from differences in landowners' decision‐making (Metzel & Montagnini, 2014) or underlying biophysical differences between properties (e.g., soil fertility) (Hall et al, 2011). Property boundaries alone do not provide insight into the socioeconomic drivers of spatial heterogeneity.…”

“…However, areas with tree cover increases are spatially dispersed and counterbalanced by areas with tree cover loss (Tarbox et al, 2018). Stakeholders in the Azuero are increasingly expressing concern over forest scarcity, leading to community‐driven efforts to restore tree cover to degraded lands (Garen et al, 2009; Metzel & Montagnini, 2014). Local interest in restoration parallels national‐scale initiatives, such as Panama's Alliance for One Million, which seeks to restore tree cover to 1 million ha of degraded land.…”

“…Land management choices can result in different disturbance regimes (e.g., burning, clearing) that influence forest recovery (Mesquita et al, 2001). Landowner preferences also influence species abundance and ecological dynamics that shape recruitment (Griscom et al, 2009; Metzel & Montagnini, 2014). For example, when deciding whether or not to enable natural regeneration on their properties, some farmers may favor rare species' natural regeneration rather than common species (Lengkeek, 2003).…”

Predicting forest recovery at landscape scales will aid forest restoration efforts.The first step in successful forest recovery is tree recruitment. Forecasts of tree recruit abundance, derived from the landscape-scale distribution of seed sources (i.e., adult trees), could assist efforts to identify sites with high potential for natural regeneration. However, previous work revealed wide variation in the effect of seed sources on seedling abundance, from positive to no effect. We quantified the relationship between adult tree seed sources and tree recruits and predicted where natural recruitment would occur in a fragmented, tropical, agricultural landscape.We integrated species-specific tree crown maps generated from hyperspectral imagery and property ownership data with field data on the spatial distribution of tree recruits from five species. We then developed hierarchical Bayesian models to predict landscape-scale recruit abundance. Our models revealed that speciesspecific maps of tree crowns improved recruit abundance predictions. Conspecific crown area had a much stronger impact on recruitment abundance (8.00% increase in recruit abundance when conspecific tree density increases from zero to one tree; 95% credible interval (CI): 0.80% to 11.57%) than heterospecific crown area (0.03% increase with the addition of a single heterospecific tree, 95% CI: À0.60% to 0.68%). Individual property ownership was also an important predictor of recruit abundance: The best performing model had varying effects of conspecific and heterospecific crown area on recruit abundance, depending on individual property ownership. We demonstrate how novel remote sensing approaches and cadastral data can be used to generate high-resolution and landscape-level maps of tree recruit abundance. Spatial models parameterized with field, cadastral, and remote sensing data are poised to assist decision support for forest landscape restoration.

Exploring farmer perceptions of agroforestry via multi-objective optimisation: a test application in Eastern Panama

Understanding farmers’ perceptions of and preferences towards agroforestry is essential to identify systems with the greatest likelihood of adoption to inform successful rural development projects. In this study we offer a novel approach for evaluating agroforestry systems from the farmer perspective. The approach couples rapid rural appraisal and normative optimisation techniques to determine favourable land-use compositions for meeting various socio-economic and ecological goals, based on farmers’ empirical knowledge and preferences. We test our approach among smallholder farmers in Eastern Panama, obtaining data from household interviews and using hierarchical cluster analysis to identify farm groups with similar land-use and income characteristics. We found that moderate differences in farmers’ perceptions between these groups altered the type and share of agroforestry included in the optimised land-use portfolios that balance the achievement of 10 pre-selected socio-economic and ecological objectives. Such differences provide valuable information about potential acceptability of agroforestry within each group. For example, we found that farmers who derive most of their farm income from crops may be more willing to adopt silvopasture, whereas farmers who are more economically dependent on cattle may benefit from diversifying their land-use with alley cropping. We discuss the potential of this modelling approach for participatory land-use planning, especially when dealing with small sample sizes and uncertainty in datasets.

“…The forest transition represents an important opportunity to enhance carbon uptake in changing landscapes through policy support, the manipulation and choice of tree species, and engagement in landscape recuperation in already inhabited places. While increasing attention focuses on constructing institutions and policies for secondary forest landscapes, how these translate into carbon dynamics remains largely unstudied [158,159,160,161,162]. Further, these systems are socially complex and the array of property and use regimes that surround them differ greatly among regions.…”

In the developed world, discussions of climate change mitigation and adaptation tend to focus on technological solutions such as decarbonizing electric grids and regulating emissions of methane, black carbon, and so on. However, an often overlooked strategy for reaching greenhouse gas reduction targets in much of the developing world is rooted, not in new technologies, but in vegetation management. Trees and other vegetation absorb carbon as they grow and release carbon when they are burnt, so landscapes function as carbon sinks and carbon storage sites when forests are growing, on one hand, and as carbon sources when forests are cleared, on the other. Since greenhouse gas emissions from such land use changes rival emissions from the entire transport sector, trees and vegetation are essential to efforts to slow and adapt to climate change. Under the right circumstances, vegetation recovery and its carbon uptake occur quickly. Moreover, carbon uptake can be strongly affected by human management of forests; the right kinds of management can improve rates of recovery and carbon sequestration substantially. This chapter reviews carbon dynamics in mature forests, secondary forests, agroforests and tree landscapes in urban areas to point out the variability of these systems and the potential for enhancing carbon uptake and storage. Furthermore, vegetation systems have many additional benefits in the form of other environmental services, such as improving livelihoods, subsistence insurance habitat, microclimates, and water systems. Finally, by managing forests better, we can also make significant contributions to climate justice because most global forests and forested landscapes are under the stewardship of small holders.
