As people fled the conflict, secondary forests dominated by broadleaf oaks, were given a chance to regrow until peace settled over the region in 1992. As farmers and community members returned to the region faces the emergence of an old problem.

These forests remove carbon from the atmosphere, filter rivers and streams that locals use for their only water source, and provide soil stability to the more mountainous regions.

Voice over by Stephen Zimmerman In collaboration with the Earth Institute at Columbia University ABES Project, the DEVELOP Fall 2015 El Salvador Ecological Forecasting team has set out to make a Land Use/Land Cover map and a forecast model using TerrSet Land Change Modeler that will allow the community in La Mancomunidad La Montañona & the project end-users, MARN, to monitor the condition of their forests, anticipate changes, and mitigate potential issues.

The satellites then begin to orbit the ‘earth.’ Voice over by Jordan Ped To accomplish these tasks, a combination of Landsat CDR 4 and 5 TM and Landsat CDR 8 OLI were obtained from USGS for the years 1986 through 2014. Additional data was provided by our partners including higher resolution imagery from Rapid Eye and QuickBird Satellites and field surveys of small plots throughout the area.

ArcGIS and Earth Engine were used to test multiple supervised classification methods.

Credit line: Created in ArcGIS Voice over by Jordan Ped The classifications from 1986 and 2014 were used as the baseline inputs for the development of a forecast model over the longest historical time period available.

Voice over by Susannah Miller Using a more accurate classification created with high resolution RapidEye to validate our classifications, a percent similar statistic comparing land classes on a pixel-by-pixel scale was calculated.

Voice over by Susannah Miller Therefore a more robust accuracy assessment was performed using ABES plot level data for forest, crop, and pasture. This ground truth combined with 60 randomly selected points from the urban and water classes were compared to the earth engine random forests classification, the overall accuracy was determined to be 61.5% Music in the background -- "Thatched Villagers" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 http://creativecommons.org/licenses/by/3.0/ 3:19-3:25: Video clip showing the forecast using LandTrendr Voice over by Susannah Miller Overall, this is not the land use or land cover we expect to see in La Mancomunidad la Montañona in 2030.

Voice over by Susannah Miller Even though this would be great it is more likely due to an error in the forecast model because it contradicts the trends that are currently being observed with further refinement of training sites and better change variables the model could be greatly improved during the spring 2016 term Music in the background -- "Thatched Villagers" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 http://creativecommons.org/licenses/by/3.0/ 3:32-3:41: Whiteboard mountain Voice over by Courtney Duquette Determining the most accurate classifications algorithm will help to build a baseline for future classifications, allowing for long term monitoring in the region and throughout El Salvador Music in the background -- "Thatched Villagers" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 http://creativecommons.org/licenses/by/3.0/ 3:42-3:55: Five photos from the ABES Project showing some of the farmers.
