(Second in a series of three posts).
This weekend, Friday Night at the Movies features a special, 6-part presentation on space-based agricultural sensing and the role it plays in understanding global food production, land and water use, food security, agricultural economics, and monitoring impacts of climate change on growing patterns.
Episodes 3 and 4 of NASA’s, Science for A Hungry World series appear below the fold; links to all appear at bottom.
Episode 3. Episode three explores land cover and land use change, including how remote sensing data is used to measure land given to agricultural use and where farms are in relation to population density. Also discussed are transitions between native vegetation, farms, and cities, and where land use changes have been most significant.
Episode 4. This episode discusses food security and how the Famine Early Warning System Network (FEWS NET) helps governments and aid agencies assess the need for food aid before a famine develops.
