More than a billion people go hungry each day - about the same number as did in the late 1950s. That's both a "tragedy on a grand scale" and an "astounding success," according to a new report called "Millions Fed," produced by the International Food Policy Research Institute and the Bill and Melinda Gates Foundation.

While the absolute number of hungry people is the same as it was 40 years ago, the proportion is dramatically smaller - one in six today, compared to one in three then, the report said. It illustrates 20 successful case studies where progress has been made in the fight against hunger.

Some solutions come from science: new varieties of wheat, rice, beans, maize, cassava, millet and sorghum. Others deal with markets, government policies, or the environment.

Two farmers from the Sahel region of Africa, oft plagued by drought and famine, visited Washington last month to talk about solutions they found close to home — one of the success stories trumpeted in "Millions Fed."

Almost 30 years ago, farmers in Burkina Faso experimented with a traditional technique called "zai," digging pits in their plots and adding manure to improve soils before the rainy season, resulting in dramatically better yields.

"There was a long period of drought in my village," Yacouba Sawadogo told reporters. "Many people left because their life was very, very difficult. But I decided to stay," he said, explaining how he taught others the technique.

In Niger, farmers manage trees on their land to prevent erosion, improve yields, and provide livestock fodder. Before, women had to walk 6 miles to get firewood, but now they have enough for themselves and to sell to others, said Sakina Mati, who coordinates tree projects in six villages.

The projects have improved 13 million acres of farmland and fed 3 million people, said Oxfam America, a development group that works with the farmers.

It's food for thought as rich nations ramp up efforts to help small farmers grow more food in poor countries. "In our approach toward solutions and programs, we really need to listen as well as talk," said Gawain Kripke of Oxfam.

"Solutions don't always come from us."
