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.

The emergence of conservation agriculture (CA) has been one of the most notable success stories in rainfed agriculture of modern times. Low-toxicity, non-selective herbicides and specialized machinery led to CA taking off in the late 1980s. CA is based on three principles:

1. Minimum mechanical soil disturbance
2. Permanent organic soil cover
3. Diversification of crops in sequences and/or associations
