Research Interests Molly E. Brown, PhD

I have two decades of experience in interdisciplinary research using satellite remote sensing data and models with socio-economic and demographic information to better understand food security drivers. I have worked on conflict, climate, and agricultural development impacts on communities in Africa and Asia, with a focus on improving decision making at a variety of scales. I have projects in Africa and south Asia and lived in Senegal while in the Peace Corps in the early 1990s. I have published over 120 journal articles in a variety of disciplines and have two books. In 2015, I was the lead author of a US Climate Assessment report published by the US Department of Agriculture entitled ‘Climate Change, Global Food Security and the U.S. Food System’. Previously, I worked for thirteen years first as a contractor and then as a civil servant at NASA Goddard Space Flight Center in the Biospheric Sciences Branch. I work with the Carbon Monitoring System community to identify and document uptake of scientific data products by decision makers working to mitigate and adapt to climate change. I served as a member of the Coordination Group on Meteorological Satellites Working Group III Tiger team on Socio-Economic Benefits (CGMS), 2013-2015, the National Science Foundation (NSF) Environmental Research and Education Advisory Committee (ERE-AC), 2010-2012, and since 2017 have served as a member of the US National Academy of Sciences’ Committee on Earth Sciences and Applications from Space.

I recently have begun working with 6th Grain Corporation as their Chief Science Officer. 6th Grain is an innovative and agile digital agriculture technology company with solutions being used by leading input suppliers and other large international companies in both low and high-income country settings. 6th Grain provides high quality, actionable intelligence via mobile device that will guide focused marketing and infrastructure investments by growers and agricultural companies.

I have four areas of scientific contributions I'd like to highlight:

My early publications focused on studying climate drivers of agricultural growing seasons in Africa. This included evaluating satellite remote sensing data products and using them together with information about agricultural dynamics. During this period, moderate resolution rainfall data was still maturing as an option to monitor variability in food production, therefore there was significant scope to include vegetation together with rainfall to study changes in agricultural activity. In addition to these papers, there are also integration of satellite data into phenological models to better understand the impact of rainfall and temperature drivers on start, end and peak of the growing season in semi-arid Africa.

Another area of research includes integrating satellite observations of agricultural productivity into economic models to capture external drivers of food affordability. This area of research is interdisciplinary and challenging as it uses econometric models and framing without conforming to macroeconomic theory. It seeks to help decision makers in the humanitarian and early warning community understand the likely impact of climate extremes on food price impacts. The final paper in this series, published in 2015, focused on determining if international commodity price variability or domestic agricultural productivity was more important in determining local food basket prices.

Although droughts and extreme storms drive interannual variability in food production, connecting these weather events to changes in child nutrition in low income countries in ways that promote improved investment and decision making is more challenging. Food security is often equated with food production and agricultural activity, although there is little evidence that there is a direct link. Investment in social safety nets, education, health facilities and feeding centers can be triggered by environmental extremes if a clear connection between these climatic factors and child health outcomes can be established. This work, conducted with a team of collaborators who provide social science and demographic expertise, has been funded by a series of grants from the US Agency for International Development and the United Kingdom’s Department of International Development (DFID).

A final area of research has been focused on determining how information is used to change decision making. How do people use information? How can we measure effective outreach and communication programs? This area of research involves contributing to how we can design effective programs that allow for the co-development of knowledge with stakeholders so that our scientific data products result in changes in programming, investment and policy to improve human health and wellbeing. This research is funded primarily by the US National Aeronautics and Space Administration (NASA) via their applied sciences and carbon monitoring system programs but is also very relevant to agricultural development and food security activities. If the scientific community can more effectively engage with policy and decision makers, then the information they produce can have an impact beyond research publications.
