Conceptual Framework of Pathways Between Biodiverse Environments and Human Health and Nutrition Outcomes
We hypothesize that biodiverse environments are better able to produce ecosystem services, such as food and clean water, which, in turn, improve the quantity and quality of food consumption by children and reduce diseases, leading ultimately to better health and nutrition outcomes. Mother's time acts as a mediating factor between biodiversity and child health and nutrition outcomes.

GHSP-D-13-00055 Supplementary Material
This appendix contains a full technical description of the satellite remote sensing data sets used in the analysis of forest cover and child health and nutrition outcomes. The data sets comprise land vegetation assessments, known as the Normalized Difference Vegetation Index (NDVI) composites, and the Vegetation Continuous Fields (VCF) collection, which contains proportional estimates for different vegetative cover types.
