Delivering open source solutions to humanitarian organizations and governments in low resource settings to plan for, monitor, and respond to climate-driven disasters
2021-09-30, 15:30–16:00, Puerto Madryn

The rapid growth in Earth Observation data to monitor climate hazards has created new opportunities to leverage technology and data science to reduce the risk of droughts, floods, and tropical storms. But there are still significant barriers in accessing and using Earth Observation data operationally, especially in countries with limited resources - which are also the most affected by climate change. To help overcome some of these challenges, the UN World Food Program has developed an open source software solution called PRISM, which simplifies the process for creating an interactive web-based mapping application built on React that can visualize and analyze climate hazard data published through OGC standard web services. During this talk, we’ll present the problem we aimed to solve, the technology choices we’ve made, and our rationale for opting to go open source for this solution.

The UN World Food Program with technical support from Ovio (, has developed an source technology solution called PRISM - that provides an intuitive map-based interface to prepare for, monitor, and respond to natural hazards. PRISM has been launched in a handful of countries in Asia and new deployments are underway in Africa as well.

When coupled with WFP’s forthcoming deployment of another open source technology - the Open Data Cube - PRISM provides an intuitive tool to monitor climate risks without the need for programming or remote sensing skills. We seek to make PRISM a collaborative project and to engage the broader open source community to further improve the system and to create a support ecosystem for new deployments beyond those led by WFP.

Amit's career has included 10+ years in WFP's Vulnerability Analysis and Mapping team (VAM, which is now a division at WFP called Research Assessments and Monitoring - RAM) along with several years of software development and enterprise technology deployments in the private sector.

Eric is the CEO of Ovio - Ovio is developing a platform making it easier for developers to contribute to open-source. In parallel, they are helping social impact projects go open-source and are working with the US government, the UN World Food Programme, and others.
