Conservation Agriculture in Zambia
– Less than 120,000 farmers in 2006 to over 180,000 in 2010
practising minimum tillage
• Conservation agriculture basins and/or ripping
– Increase in district coverage (e.g. from 12 to 17 districts for CFU)
– Increase in number of actors promoting CA
– About 20% of total cultivated land is under minimum tillage
This study
– 640 households under CFU’s Conservation Agriculture Programme
(CAP I)
– Households interviewed each farming season from 2006/2007 to
2009/2010

– Mixed methods were used

Barriers to up-scaling
Cultural
– Ploughing and livestock (e.g. southern & central provinces)
– Dry season land preparation competing with other activities
Institutional
– Slow rate of commercialisation of the ripper (14% ownership in
2010)
– Lack of timely access to seed and fertiliser
– Policy environment
Technological
– Lack of suitable labour saving technologies
• Heaviness of Chaka hoe
Differences in objectives
6
– Diversifying tillage methods vs conversion & intensification
Environmental
– Flooding in basins system

Implications
Technological approach to up-scaling is necessary but
not sufficient
– Technologies must be sensitive to the end users (e.g
women)
Other aproaches are necessary
– Institutional and policy approaches
• Re-orientation of subsidy to include rippers
• Aligning government programmes (FISP) to CA
programmes and practices
