“…In the Latin American context, research demonstrates that south–north migrants may acquire agricultural land to become first‐time landowners or to expand current holdings (Aguilar‐Støen et al., ; Davis & López‐Carr, ); or may abandon agriculture, leading to forest recovery (Aide & Grau, ; García‐Barrios et al., ; Hecht, ). Research also shows that remittance receipt can encourage intensification of farming (Gray & Bilsborrow, ) or diversification of land use (Schmook et al., ; Turner et al., ). These studies suggest that migration has the transformative potential to produce “remittance landscapes” (Hostettler, ; Jokisch, ; McKay, ).…”

Research on Central American migration has revealed the importance of journeys to the global North for rural sending communities. The outcomes of south–south journeys to nearby countries are less explored, although they are commonplace. We examine Nicaraguan rural residents’ migration to other Central American countries, especially El Salvador, to understand this migration's impacts on agricultural systems and food security. Based on mixed‐methods fieldwork in north‐western Nicaragua, we find that rather than produce remittance landscapes, or an abandonment of agriculture, south–south migration is linked to the maintenance of small‐scale agricultural systems and thus food production. “Subsistence migration,” or mobility to maintain small‐scale agriculture as a food security strategy, draws attention to how these less explored forms of migration in Central America help families to persist in agriculture in a context of worsening environmental and structural conditions.

“…Participatory mapping of socio-cultural values provides a means for different sectors in a social catchment to think collectively about environmental change. Spatial platforms that apply trans-disciplinary tools facilitate integrative and engaged science with improved longterm conservation impacts (Turner et al, 2016). Accounting for a range of knowledge, plural theories, and value-frames in the application of biodiversity planning and conservation through spatial analysis improves outcomes.…”

“…The socio-political dimensions of management policy may be different from the ecological needs and management of species (Mathevet and Mauchamp, 2005). A science-engaged agenda that acknowledges social and cultural context of landscape management provides a scaffolding for effective planning (Turner et al, 2016). Conservation planning that integrates socio-cultural and ecological values identifies contingent social value-frameworks lighting pathways to potential solutions (Endter-Wada et al, 1998).…”

“…Due to the local range and trends of climate conditions and canopy deciduousness, the Southern Yucatán is an opportune area to study the variability of forest structural properties over relatively short spatial scales and temporal periods. As interannual variability in the intensity of deciduousness varies with rainfall, monitoring forest canopy conditions is valuable as a regional drought indicator, having important consequences for wildfire risk, habitat quality, and conservation planning [35,36].…”

Cross-Scale Correlation between In Situ Measurements of Canopy Gap Fraction and Landsat-Derived Vegetation Indices with Implications for Monitoring the Seasonal Phenology in Tropical Forests Using MODIS Data

et al. 2018

Deciduousness in dry tropical forests results in substantial seasonal changes to canopy gap fractions. The characterization of such structural properties over large areas is necessary for understanding energy and nutrient distribution within forest ecosystems. However, a spatial extrapolation of measurements from relatively few, spatially-concentrated field observations can yield estimated values that have questionable accuracy and precision at regional scales. This paper uses linear regression models to compare measurements of canopy gap fraction from in situ digital cover photography in the dry tropical forest of the Southern Yucatán, Mexico, to measurements of seasonal vegetation change based on three vegetation indices-the Normalized Difference Vegetation Index (NDVI), two-band Enhanced Vegetation Index (EVI2), and the Normalized Difference Water Index (NDWI)-derived from Landsat-7 ETM+ and Landsat-8 Operational Land Imager (OLI) data to gauge the ability of standardized combinations of multispectral reflectance data to accurately describe the intensity of deciduousness that occurs during the dry season. Discrete observations are compared, as well as spatially summarized values at coarser spatial scales. Model R 2 values are greater at coarse spatial scales for all vegetation indices. Models of in situ measurements of gap fraction and Landsat NDWI normalized seasonal change exhibit stronger correlation than do models that feature NDVI or EVI2 (R 2 = 0.751 and Mean Absolute Error = 0.04 after aggregation, R 2 = 0.552 and MAE = 0.07 for observation-level data). Based on its comparatively strong correlation with field observations, NDWI is adapted to a Moderate Resolution Imaging Spectroradiometer (MODIS) time series and used for spatial extrapolation and the monitoring of canopy conditions. NDWI values derived from MODIS data are regressed against Tropical Rainforest Measuring Misson (TRMM) rainfall data over the period 2000-2011, and the regression results are compared to those of a prior study that used regression to explain the variation of a MODIS EVI using TRMM rainfall data. A MODIS NDWI time series reveals stronger correlation (R 2 = 0.48 in deciduous forests) with TRMM accumulated (three-month) rainfall data than a MODIS EVI time series. The results indicate that an NDWI time series can accurately describe a variability of canopy leaf abundance during the dry season and could be an alternative basis of long-term monitoring of season phenology in a dry tropical forest.
