NASA Earth Observatory - Vegetation Index

The NDVI (Normalized Digital Vegetation Index) is on of the primary methods for detecting healthy vegetation using satellite imagery.  This also serves as a useful way to distinguish between distinct ecological and agricultural regions and the temporal patterns of planting seasons.

Food, Nutrition and Geography

Peter Menzel's beautiful photography and our Hungry Planet...

 

This video is a fascinating portal into global food systems and how globalization is impacting local foods.  He traveled around the world to see what families eat in a given week, and how much all the food cost and where it can from.  Many wealthy countries exhibit poor nutritional habits (eating food high in fat, sugar and salt) while some in poorer people have a very balanced diet.  This leads him to describe the 'Nutritional Transition.'  Warning before showing in class: there are brief instances of non-sexualized nudity in the video.
