THE United Nations on Friday appealed for $190-million to avert another major humanitarian crisis in Ethiopia. “If adequate assistance is slow in arriving, the crisis (of 1999) will not only return but will be much larger in magnitude and severity and certainly more costly to mitigate,” according to a statement released by the UN country team in Ethiopia. The statement cited drought and the war with neighbouring Eritrea as factors contributing “the current conditions that give great cause for concern” in Ethiopia.
