Full title: Sustainable Land Management in Sub-Saharan Africa_ No 6.Zaï planting pits

Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent droughts and low water productivity. There is an urgent need for better management of water on farmers' fields - and for increasing its availability through water harvesting.

These mini-films show a series of Sustainable Land Management (SLM) practices that have been proven in Sub-Saharan Africa. As well as helping to control land degradation and improve production, the practices constitute important components within the climate change adaptation strategies of small-scale farmers. An analytical conclusion is also included.

The director and script-writer, William Critchley, Senior Sustainable Land Management Specialist at the Centre for International Cooperation, VU University of Amsterdam, reviews development experience, and sets out the state of the art in Sub-Saharan Africa.

This sixth movie introduces zaï (In Burkina Faso or tassa in Niger) which are wide and deep planting pits, used in semi-arid areas as a water harvesting technique. They are commonly combined with contour stone lines which slow down runoff, increase infiltration and project the pits from sedimentation. Zaï improves plant production by concentrating rainfall runoff and can also form the basis for establishment of trees/shrubs.
