It discovered metdo which is a scientific approach to help the so-called ultra poor, one billion people around the world living on less than one euro a day, enhancing livelihoods, income and health.

It seems to work, as told in Science, scientists at Yale University who analyzed the results following the 21 thousand people's lives - among the poorest in the world - for three years, the data show that the Graduation model has led to significant and lasting improvements in the lifestyle of the analyzed citizens.
"Being ultra poor, usually," says Dean Karlan, one of the authors of the study, which also contributed to experts of the non-profit Innovations for Poverty Action (IPA), "it means something more than not having a stable income.
It means not having anything to eat, do not have the opportunity to accumulate savings, have no access to information.
We tested an approach which addressed several factors at a time and found significant improvements after only three years into the program. "
As we explained, the researchers traced the lives of 21 thousand people in Ethiopia, Ghana, Honduras, India, Pakistan and Peru, to assess the impact of a program that included six core actions: training on how to start a business to make a living (such as livestock or opening a small shop); training for the maintenance of such activities; supply of food and money to reduce the risk of selling new business in an emergency; Frequently lessons to strengthen skills; health education and access to health care; opening of a savings account to put aside the money earned.
To assess the effects of the program, the scientists used a randomized controlled trial, an experimental technique that is used for research in the biomedical field.
In practice, both have followed the people invited to participate in the Graduation model that anyone who had not been involved, to buy what their lives were changed a year after the end of the program.
Coming to the conclusion that the former had put aside more savings, they had worked more, had suffered less hungry and suffered from fewer days of stress and disease.
"Not only does the program appears to be effective," says Kate McKee, the Consultative Group to Assist the Poor in Washington, who helped implement the project, "but it represents a significant return on investment necessary.
