Anna Tompsett, Sustainable Development PhD student, explaining the
importance of mapping water availability in the Niger Inland Delta.
The River Niger flows from west to east for most of the length of West
Africa. Each year the river floods an area of tens of thousands of
square kilometres in a complex spatial pattern of channels and
islands, although the total flooded area varies from year to year. Land can
only be used for high yield crops during the flood season if there is water
access nearby.  With Dr. Chris Small of Columbia's Observatory,
Anna is in the process of analyzing satellite images and water flow records to
understand water availability.  The products under development will
eventually be available for use in  long-term or annual planning for
agriculture on a regional scale.

Hildigunnur and Jonathan describing how to increase a building's efficiency by storing excess heat generated in the winter months for conversion to energy in the summer months.

MBA student, Kevin Rehak, explaining how ChildCount works.

Applied Math PhD student, Selin Kocaman describing her work on the Network Planner, a mathematical modeling tool designed to help rural utility providers determine an optimal and cost effective path for connecting a scattered group of homes to a central-source utility like water or electricity. This is useful in determining the cheapest way to provide a village with electricity or deciding where to site a water pump.
