In the early 1990s Saddam Hussein drained what biblical scholars believe to be the Garden of Eden. With the water went the people, known as the Ma’dan, and their way of life. Now, Iraqi-American hydraulic engineer Dr. Azzam Alwash and his organization Nature Iraq, are working with the Ma’dan to restore the marshes of southern Iraq, in a project Alwash calls “Eden Again." He hopes the exiled people will come back as water and wildlife return to what had been turned into a desert, according to a segment on the PBS show, Nature.

For thousands of years the Ma’dan called the marshes home. They lived on floating islands made of reeds that grew in the marshes. They caught fish, hunted birds, and kept water buffalo, says an article from Spiegel Online. Without water this life wasn’t possible and the Ma’dan people either migrated to the city or suffered in poverty.

Alwash returned to the marshes in 2003 after Hussein fled from power. He found that those that had remained in the area had already begun to dig through the man-made embankments that diverted the Tigris and Euphrates Rivers away from the marshes, he explained in a recent NPR interview. Flash forward seven years and the Ma’dan have destroyed up to 98 percent of the embankments, Alwash tells the Guardian. Their motivations more economic, than anything else.

Not because they are tree-huggers or bird-lovers, but because it's a source of economic income to them, because they can harvest reeds and sell them. They can fish and feed a family or sell them to earn extra income.

Hundreds of thousands of Ma’dan people who have been living in urban exile are now used to many aspects of modern life, Alwash explains in another article in the Guardian. They’ve become familiar with electricity, television, air-conditioning and wifi. But Alwash sees no reason why comforts such as these can’t be incorporated into the traditional Ma’dan way of life. Once services are in place Alwash anticipates a flood of “reverse migration.”

Right now, the biggest stressors to the marshes are ongoing drought and hydro-dams in Iraq's northern neighbor, Turkey. In the NPR interview Alwash explains that the drought has reduced the marshes to about 35 percent of their former size. But Alwash is confident that 75 percent of the marshes can be restored despite the drought and dams in Turkey.

When Saddam Hussein drained the marshes in the early 1990s he attempted to turn a paradise into a desert and wipe one of the oldest civilizations on earth off the face of the earth itself. He nearly succeeded. But with the help of Dr. Azzam Alwash and Nature Iraq, the Ma’dan have proved the resilient force that nature and humanity are, as a desert becomes Eden again.

Southern Iraq is home to one of the largest wetlands in the world, where the tributaries of the Tigris and Euphrates meet. But a three-year drought in the Middle East, along with dams and water projects in neighboring countries, has left southern Iraq with a serious water shortage, reports the BBC.

For 6,000 years these wetlands have been home to people called Marsh Arabs. They made their huts out of the marsh reeds, ate fish they caught in the waters, and sold the milk and cheese they made from water buffalo milk, explains the LA Times. (A beautiful slide show of Iraq's marshlands and the Marsh Arabs accompanies the The LA Times article.) But now these wetlands are roughly 30 percent of their former size, says the BBC, and they are continuing to shrink.

The marsh's dropping water levels have devastated the wealth of the region and the livelihoods of the Marsh Arabs. Jassim Asadi, of the nonprofit conservation group Nature Iraq, tells the LA Times the marshes used to supply two-thirds of the fish consumed in Iraq. Now people buy bottled water and frozen fish imported from Iran. “It is an economic disaster,” Asadi says.

Though the drought is "the most immediate cause" threatening the wetlands and their inhabitants, regional water politics cannot be ignored, the BBC says. The Tigris and Euphrates flow through multiple countries, and the rivers are the main water source in the area. A BBC video helps break down the situation:

About 70 percent of Iraq's waters originates outside the country, in Turkey, Syria, and Iran... These countries already have ambitious damn and irrigation projects, limiting how much is left for Iraq. And yet more damns are planned — further reducing the flow into the marshes.

Some scholars and politicians remain hopeful that diplomacy and cooperation amongst the different Middle Eastern countries will allow for more equitable water management. But as things stand now, there is no immediate fix on the horizon.

They arrive during the night with their construction tools. Some come with hired security guards. These are the wetland encroachers of Kampala, hoping to claim land before the watchful eye of the National Environmental Management Authority notices and evicts them.

Poverty is compelling many people to build on the wetlands as population growth and urbanization increase land competition. The construction destroys the land's ecological value, Uganda's The Monitor reports.

Uganda's wetlands filter water and prevent destructive flooding downstream. They are also a source of material for profitable products like papyrus. Wetlands provide employment for 2.7 million Ugandans in a country where just five percent of the total work force has a consistent income.

Uganda was the first African country to develop a national wetlands program. The government has spent millions of dollars and partnered with the World Resources Institute (WRI) to develop an information system to track wetland use. Also, Ugandans who build on wetlands without permits are subject to fines and evictions.

The WRI and the Ugandan government are concerned that the services and products wetlands provide, and on which many poor households depend, are at risk. But, despite Uganda's pioneering status in wetlands management, the country faces many trade-offs as it balances land needs with the desire to preserve the ecosystem and alleviate poverty.
