Alex Orenstein

Alex is a drought specialist working with livestock herders in Africa- notably in the Sahel and Horn of Africa. His work focuses on using satellite imagery to provide meteorological information to farmers and herders to help them anticipate droughts and climate shocks. Since 2014, he has been the livestock and GIS specialist for GARBAL, a call center that provides agricultural and meteorological information to farmers and herders in Mali, Niger and Burkina Faso. Over the past 15 years, Alex has developed a series of tools that use satellite imagery to model food insecurity that have been used by NGOs, UN Agencies and several governments in Africa. In 2024, Alex developed the first comprehensive map of seasonal livestock movements in Somalia in over 40 years.
