These are really beautiful and interesting, but I wish photos could also reveal what substances are used on the land: fertilizers, pest killers, etc. I will go to his site and see if he addresses that.
"In many cities, it's become popular to hate 'gentrifiers,' rich people who move in and drive up housing prices -- pushing everyone else out. But what's going on in these rapidly-changing urban spaces is a lot more complicated than that."
"It's perfectly human to grapple with questions, like 'Where do we come from?' and 'How do I live a life of meaning?' These existential questions are central to the five major world religions -- and that's not all that connects these faiths. John Bellaimey explains the intertwined histories and cultures of Hinduism, Judaism, Buddhism, Christianity and Islam."
"To be honest I do not know what they make of my beans," says farmer N'Da Alphonse. "I've heard they're used as flavoring in cooking, but I've never seen it. I do not even know if it's true." Watch how the Dutch respond to a cocoa bean in return or you can watch our entire episode on chocolate here.
"The global Multidimensional Poverty Index (MPI) is an international measure of acute poverty covering over 100 developing countries. It complements traditional income-based poverty measures by capturing the severe deprivations that each person faces at the same time with respect to education, health and living standards."
"Today, innovation is taking place where people can come together, not in isolated spaces. Innovation districts are this century's productive geography, they are both competitive places and 'cool spaces' and they will transform your city and metropolis."
"Seldom has it been more important for Americans to form a realistic assessment of the world scene. But our current governing, college-educated class suffers one glaring blind spot.
Modern American culture produces highly individualistic career and identity paths for upper- and middle-class males and females. Power couples abound, often sporting different last names. But deeply held religious identities and military loyalties are less common. Few educated Americans have any direct experience with large groups of men gathered in intense prayer or battle. Like other citizens of the globalized corporate/consumer culture, educated Americans are often widely traveled but not deeply rooted in obligation to a particular physical place, a faith or a kinship."
"While people often say that borders aren’t visible from space, the line between Kazakhstan and China could not be more clear in this satellite image. Acquired by the Landsat 8 satellite on September 9, 2013, the image shows northwestern China around the city of Qoqek and far eastern Kazakhstan near Lake Balqash.
The border between the two countries is defined by land-use policies. In China, land use is intense. Only 11.62 percent of China’s land is arable. Pressed by a need to produce food for 1.3 billion people, China farms just about any land that can be sustained for agriculture. Fields are dark green in contrast to the surrounding arid landscape, a sign that the agriculture is irrigated. As of 2006, about 65 percent of China’s fresh water was used for agriculture, irrigating 629,000 square kilometers (243,000 square miles) of farmland, an area slightly smaller than the state of Texas.
The story is quite different in Kazakhstan. Here, large industrial-sized farms dominate, an artifact of Soviet-era agriculture. While agriculture is an important sector in the Kazakh economy, eastern Kazakhstan is a minor growing area. Only 0.03 percent of Kazakhstan’s land is devoted to permanent agriculture, with 20,660 square kilometers being irrigated. The land along the Chinese border is minimally used, though rectangular shapes show that farming does occur in the region. Much of the agriculture in this region is rain-fed, so the fields are tan much like the surrounding natural landscape."

"From the time we’re about 6 years old, everyone loves a good poop joke, right? But is there something more meaningful lurking beneath the bathroom banter? Take a look at some international potty humor and then follow the jokes to a deeper understanding. Every laugh on this page reflects a life and death issue: the very real sanitation problems facing India today."
"One-third of the seafood Americans catch is sold abroad, but most of the seafood we eat here is imported and often of lower quality. Why? Author Paul Greenberg says it has to do with American tastes."
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.
A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.
In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.
The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.
"The largest reservoir in the U.S. falls to its lowest water level in history, Nevada State Sen. Tick Segerblom introduced a bill title and issued a press release on July 8 calling for an 'independent scientific and economic audit of the Bureau of Reclamation’s strategies for Colorado River management.'"
This week’s history-making, bad-news event at Lake Mead has already triggered lots of news stories, but almost all of these stories focus on the water supply for Las Vegas, Phoenix and California. But what about the health of the river itself?
"With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites."
"There are more people displaced by violence and conflict on the planet right now than at any time since World War II. The United Nations Refugee Agency (UNHCR) says the number of people forcibly displaced, including refugees, asylum-seekers, and internally displaced persons has now reached over 51 million."
With Tuesday's seizure of Mosul, Iraq's second largest city, the Islamic State of Iraq and Syria notched a major victory in its campaign to create a new country containing parts of what had part of both Syria and Iraq. On Wednesday, the insurgents continued their march south, taking control of Tikrit, the hometown of Saddam Hussein.
The story of ISIS's spread -- and its influence -- is one that begins in Syria, where the group has been waging a brutal insurgency against the regime of Bashar al-Assad and, increasingly, other more moderate and secular rebel groups. The map above depicts the areas of Syria under its control. The group's influence is bounded by the Free Syrian Army in the west, the Kurds in the north, and pockets of government influence. Who is the ISIS/ISIL?
