Niger: A transformed agricultural landscape –

5 million hectares of farmer managed natural regeneration

Wet season millet production

What lies beneath?• Recognition of the multiple

benefits of the Faidherbia albida and other multi-purpose species

• Research perfecting propogation methods, density, adaptation to farming systems

• Grassroots village level institutional strengthening – access new knowledge on management systems

• Policies - Niger government reform of forestry laws

• National Agroforestry food security program (Malawi)

• Partnerships and Donor Support

Tanzania - Shinyanga Ngitili System 500,000 hectares regenerated

Ngitili System - Shinyanga

What lies beneath?

• Severely degraded lands – due to deforestation (tse-tse fly)

• Shinyanga Soil Conservation project; National Agroforestry Research Centre

• Grass roots leadership - close collaboration between farmers, scientists and local government

• Implementation rooted in government structures allowing efforts to continue beyond project funding cycle

• Planned and controlled grazing

• Timing not numbers of animals

• Deep rooted diverse perennial species

• Full soil cover

• Prohibit burning

• Plan for drought in time and not spacePhoto credits: A. Savory

What lies beneath?

• A visionary prepared to challenge paradigms

• Addressing root causes• Understanding among

livestock and wildlife stakeholders

• Relevance to sustainable community development

• Enhancing the value chain• Capacity development• Influence on future policies

What lies beneath?

• Access to productive inputs• Agro-ecological approaches• Investments in capacity

development – farmer leaders

• Farmer cooperation (mingas)

• Passing on the gift• Strong linkages with local

and national government• Productivity

What lies ahead?• National Investment Strategies –

Cross-sectoral coordination and multi-stakeholder processes

• Bridging UN Conventions

• Stronger linkages among research, practice, knowledge sharing and policy

• Urban rural linkages – sustainable food and energy producing landscapes with Local government driving – (home grown…)

• Assessments - Life cycle analysis, farming system and landscape level assessments - mitigation and adaptation potentials
