SSSA definition:
“Managing soil and crop cultural practices so as not to degrade or
impair environmental quality on or off site, and without eventually
reducing yield potential as a result of the chosen practice through
exhaustion of either on-site resources or non-renewable inputs”

General considerations
• Set of principles for SSM
• Consider challenges and priorities in regions and individual countries
• Priorities:
– Soil organic matter / soil carbon
– Maximize organic/mineral input efficiencies
– Education in soil science
– Platform for information exchange
– Increased voice of soil scientists at policy level

Policies
• SSM Policy recommendations to governments
• Create favourable socio-economic and policy environment for farmers to invest in soils
• Direct investments in sustainable soil fertility management
• All countries encouraged to develop a national soil policy

• Partner with CAADP (10% of annual budget)
• Regular meetings of agricultural ministers
• Practice of balanced nutrient management to “kick-start” biomass production
• National ministers to agree on holistic farming systems
Policies

• Food security as main driver of SSM
• Communication plan for stakeholders, including schools and public
• Implementation and scaling out of practices and knowledge
• Common understanding of SSM, including social and ethical dimensions
Awareness

Partnerships
• Africa should drive the process!!!
• Establish linkages with key stakeholders and sectors
• Tailor messages and info to specific sectors

• All activities that assist soil restoration • Intensify agriculture based on using external and
internally recycled nutrient resources • No-till farming where appropriate • Crop rotations • Efficient plant nutrition • Irrigation according to technical parameters • Integrated soil and water management at
watershed level • Develop private/public partnerships to support
