Ethiopia is constructing a $4.8 billion dam along the Nile River that has Egypt angry. The Grand Ethiopian Renaissance Dam, or GERD, will have a capacity of 6.45 GW, doubling the country’s power capacity. It will provide electricity to 60% of Ethiopian households and create a massive reservoir for tourism and the fishing industry. However, the project poses a threat to Egypt, who relies heavily on the Nile River. This has led to tensions between the nations and a political battle over the river.

A recently donated film to the Public Policy collections of the Mudd Manuscript Library, long thought lost has been digitized and is now viewable online. "Segregation and the South," a film produced in 1957 by the Fund for the Republic, reported on race issues in the South since the 1954 Supreme Court decision in the Brown v. Board of Education case. It examined the slow progress of integration at elementary and secondary schools and colleges, as well as the white backlash to the decision. It also documented the Montgomery bus boycott. Much of the footage came from news organizations like CBS and NBC that was re-packaged, but some original material was filmed in Clarksdale, Mississippi, by writer and director James Peck. Broadcast on June 16, 1957, a Sunday, from 5-6 p.m., it aired on over 30 ABC affiliates, 12 in the South, but none in the Deep South.
This film is detailed in our blog: The entire finding aid for the Fund for the Republic collection can be found here: http://findingaids.princeton.edu/collections/MC059
In places around the world, supplies of groundwater are rapidly vanishing. As aquifers decline and wells begin to go dry, people are being forced to confront a growing crisis.
Much of the planet relies on groundwater. And in places around the world – from the United States to Asia, the Middle East, Africa and Latin America – so much water is pumped from the ground that aquifers are being rapidly depleted and wells are going dry.
Groundwater is disappearing beneath cornfields in Kansas, rice paddies in India, asparagus farms in Peru and orange groves in Morocco. As these critical water reserves are pumped beyond their limits, the threats are mounting for people who depend on aquifers to supply agriculture, sustain economies and provide drinking water. In some areas, fields have already turned to dust and farmers are struggling.
Climate change is projected to increase the stresses on water supplies, and heated disputes are erupting in places where those with deep wells can keep pumping and leave others with dry wells. Even as satellite measurements have revealed the problem’s severity on a global scale, many regions have failed to adequately address the problem. Aquifers largely remain unmanaged and unregulated, and water that seeped underground over tens of thousands of years is being gradually used up.
In this documentary, USA TODAY and The Desert Sun investigate the consequences of this emerging crisis in several of the world’s hotspots of groundwater depletion. These are stories about people on four continents confronting questions of how to safeguard their aquifers for the future – and in some cases, how to cope as the water runs out.

Sequential hermaphroditism occurs when an organism changes sex at some point in its life. It’s seen in a few species of gastropods and plants, but mostly fish, like napoleon wrasse, clownfish, groupers and marine angelfish. This transformation involves the complete restructuring of their gonads, as well as changes in their morphology and behaviour. For these fish, sex change is a usual part in their life cycle, and it’s one that carries adaptive advantages.

Every day, thousands of Ethiopians set off on foot on a desperate 2,000-kilometre trek in the hope of reaching Saudi Arabia. Their route takes them across the Djibouti desert, the Red Sea and Yemen, a country ravaged by civil war. Every year, hundreds die of exhaustion in the desert or drown while crossing the Gulf of Aden. Those who make it to Yemen, often having starved for days on end, are easy prey for the local mafia who kidnap them for ransom. Our reporters followed these migrants on their journey and documented, with exclusive footage, the extent of human trafficking.
