The U.S. Department of Agriculture (USDA) and the National Aeronautics and Space Administration (NASA) signed a Memorandum of Understanding (MOU) to strengthen collaboration. In support of this collaboration, NASA and the USDA Foreign Agricultural Service (FAS) jointly funded a new project to assimilate NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) data and products into an existing decision support system (DSS) operated by the International Production Assessment Division (IPAD) of FAS. To meet its objectives, FAS/IPAD uses satellite data and data products to monitor agriculture worldwide and to locate and keep track of natural disasters such as short and long term droughts, floods and persistent snow cover which impair agricultural productivity. FAS is the largest user of satellite imagery in the non-military sector of the U.S. government. For the last 20 years FAS has used a combination of Landsat and NOAA-AVHRR satellite data to monitor crop condition and report on episodic events.
To successfully monitor worldwide agricultural regions and provide accurate agricultural production assessments, it is important to understand the spatial distribution of croplands. To do this a global croplands mask to identify all sites used for crop production. Croplands are highly variable both temporally and spatially. Croplands vary from year to year due to events such as drought and fallow periods, and they vastly differ across the globe in accordance with characteristics such as cropping intensity and field size. A flexible crop likelihood mask is used to help depict these varying characteristics of global crop cover. Regions featuring intensive agro-industrial farming practices such as the Maize Triangle in South Africa will have higher confidence values in the crop mask as compared to less intensively farmed regions in parts of Sub-Saharan Africa where cropland identification is partly confounded with natural background vegetation phenologies. Thus, a customized threshold can be employed to examine areas of varying cropping intensification.

Restricting the volume of high-emitting vehicles roaming city streets carries many benefits, from clearing the air to quieting the urban din and beyond. Recognition of this simple fact has led to the proliferation of clean air zones, designated regions within a city where vehicles must meet strict pollution standards or pay a fee to operate […]

From a small collection of villages on the banks of the Tiber to the greatest empire the ancient world had ever seen — and then the long, extraordinary unravelling of it all. In 44 minutes, we cover the full sweep of Roman history: the founding myths, the Republic, the brutal beauty of the Roman army, the assassination of Caesar, the rise of Augustus, the emperors who built it and the emperors who nearly destroyed it, the gladiators, the aqueducts, the roads that still exist today, and the slow collapse of a civilisation that shaped virtually everything about the world we live in. This is Rome — all of it — told the way it deserves to be told.
The Persian Qanat: Ancient Desert Engineering. Discover the incredible engineering feat of the Persian Qanat, an ancient system dating back 3,000 years.

Learn about the meticulous construction process, the annual maintenance required, and how this technology spread across the world through trade and conquest.
When William of Normandy invaded England in 1066, it began a transformation of the Old English language. The Norman conquerors replaced the Anglo-Saxon ruling class, bringing with them their Anglo-Norman language, which was based on Old French. Over time, the two languages blended. Old English grammar became simpler, and the English vocabulary expanded with the addition of French words. The result was a new stage of the English language: Middle English, spoken around 1100 to 1500. During this time, Geoffrey Chaucer wrote The Canterbury Tales, one of the most famous examples of Middle English literature. Chaucer’s writing — and the English language in general — was not uniform at this time. Spellings varied and were often phonetic, and pronunciation differed by region; Chaucer often used whichever version of a word fit his rhyme. There were some differences between the Middle English alphabet and our ...Read More
