Building a Consolidated Community Global Cropland Map

Hybrid cropland map of Africa produced by IIASA/IFPRI developed as part of [10]A new Sub-Task on Agricultural Mapping is building a living, community-based consolidated cropland map. The aim is to provide the agricultural monitoring, food security and land use change communities with a better cropland product than currently exists. The product is freely available to researchers and the general public.

Remote Sensing of Alkaline-Saline Lakes: Applications to Flamingo Conservation

Image of arthrospira fusiformis, the dominant phyoplankton species in Lake Bogoria.The lesser flamingo of Kenya and Tanzania is a near-threatened species that feeds on bacterial biomass growing in the soda lakes of the Rift Valley. This interdisciplinary project investigates the connections between ecological and hydrological processes in alkaline-saline lakes, and demonstrates how satellite data can contribute to remote monitoring of ecosystems.

Water Availability in Reference to Water Needs in Poland: The Importance of Correct Estimation of Water Resources

Map showing average annual precipitation in Europe over the period of 1940-1995The improper selection of indicators of water resources can lead to inaccurate estimates of supply and may complicate the management of these vital resources. This paper discusses the benefits of using Earth observation technology in the Global Monitoring for Environment and Security program for estimating water resources in Poland.

Large X-class Flare Erupts on the Sun

Large X-class Flare Erupts on the Sun

On Jan. 27, 2012, a large X-class flare erupted from an active region near the solar west limb. X-class flares are the most powerful of all solar events. Seen here is an image of the flare captured by the X-ray telescope on Hinode. This image shows an emission from plasma heated to greater than eight million degrees during the energy release process of the flare. Image Credit: JAXA/Hinode
