Service Description:

The majority of calculations were done using the Google Earth Engine. The hotspots and other post-processing routines were done locally in Matlab, R, and Python. Final products were mapped in ArcGIS and Illustrator.

Hotspots were defined for each indicator. To reduce bias across the range of habitats and agricultural practices, hotspots were identified for the agricultural land within each individual biome. We developed a preliminary validation data base from using geo-tagged photographs (683) and field observations (15,500). Degraded lands maps for three countries were used for a visual comparison with the maps developed here. TNC staff and partners from Mexico, Colombia, Brazil, and Argentina provided all validation and comparison data. Maps of each indicator will be further refined as our work moves from planning to the implementation stage.

Title: Degraded lands and soils_WTL1
Author: pilar.lozano@tnc.org_TNC
Comments:
Subject: We improved methods to map degraded lands and soils for targeting restoration efforts for improving agricultural productivity and eventually tracking the impact of TNC’s strategies. Further, existing products largely reflect land use change rather than degradation of croplands and pastures.
