Given the recent trend of granting vast areas of African land to foreign investors, the urgency of placing real ownership in the hands of the people living and making their livelihood upon lands held according to custom cannot be overstated.

Protecting and enforcing the land rights of rural Africans may be best done by passing laws that elevate existing customary land rights up into nations' formal legal frameworks thereby making customary land rights equal to documented land claims.

Throughout its history, Mozambique has had to deal with cyclones and floods, and when these are severe they have a devastating impact. Apart from the immediate threat to human life, such natural disasters seriously impede economic growth.

At least 700 people died, and some 500,000 to 650,000 were displaced and temporarily sheltered in over 100 camps set up by the government.
