Right Livelihood Award winners announced in Stockholm 26 (UPI) -- Four men were named Thursday in Stockholm as winners of the 2013 Right Livelihood Awards, which honor practical work to solve the world's problems. This year's honorees are Paul Walker of the United States for working to rid the world of chemical weapons, Raji Sourani for human rights work in the Palestinian Authority, Dennis Mukwege of the Democratic Republic of Congo for helping women who have been victims of sexual violence during the fighting there, and Hans R. Herren of the Biovision Foundation in Switzerland. Sourani is the first Palestinian to receive the award. The awards were established in 1980 by Jakob von Uexkull, a Swedish-German philanthropist who sat in the European Parliament as a member of the Green Party. They are sometimes thought of as an alternative to the Nobel Prize, also presented in Sweden. "The world should not have to live with problems that we know we can solve," said Ole van Uexkull, executive director of the Right Livelihood Award Foundation. These four men, whose vision, courage and commitment we honor today, show what the solutions look like.
