South Sudanese emigrants have returned home to joint the effort.

A doctor said the population of south Sudan is 8 million but it has only less than 3 hundred doctors and 20 experienced maternity nurses. "That's why I returned," he said.

A businessman who had studied in Egypt and Europe and worked in Germany as an economic expert also came back to south Sudan to launch an effort for developing civic organizations.

He said if south Sudanese experts returned from abroad, they could make a great contribution to the reconstruction of the state.

South Sudanese people living in other countries have technologies and fund badly needed by the country. Therefore, they can play a big role in bringing a change to its people.
