DEVELOP's Chesapeake Bay Agriculture project was featured by NASA's Earth Observatory. The primary goals of this project were to automate key steps in acquiring yearly satellite imagery and compute vegetation metrics to assess winter cover crop performance in the Chesapeake Bay. As a test case, four Maryland counties were used to calculate NDVI derived biomass, nitrogen content, and percent nitrogen by field from 2006-2016. In addition, software was developed to calculate the same metrics in future years. Monitoring cover crop performance in the Chesapeake Bay using Earth observations (EO) allows the MD Department of Agriculture (MDA) to confirm cover crop implementation and to inform adaptive management.

On April 5, 2017, the Embassy of Costa Rica in the United States hosted an Ambassador-level Dialogue on Disaster Risk Reduction across the Americas. The goal of the dialogue was to build cohesion, promote strong partnerships amongst stakeholder countries, and build on the emphasis of science and technology in disaster risk reduction, as called for under the SENDAI framework. The event, which was facilitated by the NASA Disasters Program, with participation from NOAA and USGS leadership, also highlighted the important role that Earth Observations and remote sensing imagery and data have in helping decision makers better prepare for, respond to, and recover from disasters. The event took place as one of a series of related meetings and conferences across the Americas, which will culminate with a regional Disaster Risk Reduction across the Americas Summit in Buenos Aires on September 4, 2017. Representatives from embassies of 15 countries attended, including many Ambassadors.
