Effective African and international action 10 years ago could have averted today's disasters. Unless the roots of Africa's problems are more effectively addressed today, a succession of similar calamities is certain over the coming decades. It is absolutely critical that more vigorous efforts begin now towards the saving of Africa's future. Structural causes 3. African countries have been devastated by a combination of domestic policy shortcomings, extremely rapid population growth, civil strife, external destabilization and, most recently, savage blows from the world economy and natural disasters. Africa's uniauely fragile economies, struck by severe shocks - relatively much more severe than those suffered by others - have been less able either to develop appropriate policy response or to draw on flexible sources of external supportive credit. Massive retrenchment, the breakdown of institutions, suffering and, now, starvation, were the inevitable outcome. 4. The shocking circumstances of today's Africa can and must be overcome.

There is technical agreement that domestic policy reform and improved external support make up an inseparable package. Increased support for agriculture, through restructured institutions and incentives, is the crux of the required domestic policy change. Restored levels and more appropriate
