A drone capture of a smallholder farming landscape. Overlaid are squares of the size of typical optical satellite missions. Openly accessible data (e.g. Landsat or Sentinel-2) is often not sufficient to capture the landscape complexity in full detail, for example when trying to delineate individual fields. Here, one Landsat pixel contains fractions of multiple fields. Commercial data come at higher spatial resolution, offering potential to discriminate indivudual landscape components.

📣PNAS piece led by @philrufin.bsky.social: commercial very-high-resolution EO data is needed for monitoring SDG 2 indicators in smallholder landscapes but costs are prohibitive. A call for open access for sustainability-centered research: doi.org/10.1073/pnas... @humboldtuni.bsky.social

Tree Species Diversity, Composition and Aboveground Biomass Across Dry Forest Land-Cover Types in Coastal Ecuador - Xavier Haro-Carrión, Bette Loiselle, Francis E. Putz, 2021 Tropical dry forests (TDF) are highly threatened ecosystems that are often fragmented due to land-cover change. Using plot inventories, we analyzed tree species...

Some of my past work: In Ecuador’s TDF, mature forests hold the most tree diversity and AGB. Secondary and plantation forests have similar ABG but differing diversity, showing the need to include diversity in biomass-focused conservation. Check it out:

Spatiotemporal changes in vegetation greenness across continental Ecuador: a Pacific-Andean-Amazonian gradient, 1982–2010 The tropics are greening, but little is known about greening patterns in the tropical Andes. Using Normalized Difference Vegetation Index (NDVI) data on monthly and annual bases, this research anal...

Some of my past work: Tropical greening is well-known, but this study shows differences in Ecuador's Coastal, Andean, and Amazon regions. Growing seasons lengthen in the Amazon / West Andes, while greening without shifts occurs elsewhere. Check it out: www.tandfonline.com/doi/full/10....
