1. Genetic diversification and intensification:
Experiences from Kongwa and Kiteto, Tanzania

ICRISAT
Africa RISING East and Southern Africa Review and Planning Meeting,
Malawi, 14-16 July 2015
2. Project sites
Kiteto district is found in the Manyara
region with an estimated population of
152,757
Kongwa District is found in Dodoma
Region. We are working in Mlali ward with
a population of about 28,000 people

5. Context
Development challenges
• Under-investment in productivity
enhancing technologies.
• Limited access to technology and
delivery–60-70% of households had not
contact with research & extension;
• Limited access to agric. financing;
• Un-managed risks increase exposure to
variability in weather patterns with
periodic droughts;
Impacts
• Low productivity of crops and
livestock –crop yield gaps>50%
• Fragile production to market
systems.
• High vulnerability to weather
and other natural disaster
related challenges
• High levels of poverty and food
insecurity:
• >35.5% live below the food
poverty line
6. The research issues
Focus
• Improve productivity of crops and livestock
• Reducing vulnerability to weather
• Minimizing health risk from crops to improve
wellbeing and competitiveness
• What are the best technology packages
that can catalyze improvement in
productivity, resilience and value chain
functionality for KK
7. Impact
Economic and ecological rewarding pathways out of hunger and poverty improve prospects for for
smallholder families in Semi arid areas of central Tanzania

• Productivity at 50% of potential yield for above crops
• Farmers involved in extensive farming using mechanized agriculture
11. Kiteto and Kongwa
• Frequent drought, poor nutrition are among the challenges faced by the
majority areas in target locations
• Low adoption of priority crops, high yielding varieties and poor access to
quality seed

a) Augmented cropping options
• Double up legumes (Leguminous crop + fodder tree)
• Resilient varieties + judicious soil fertility/water management + crop
architecture
b) Land productivity
• Ecological land and soil management for feed and food
c) Crop/poultry production systems for food, fertility and incomes

1. Integration. Complex institutional and operational relationships.
Varied biophysical contexts
Socio economic contexts: Power relationships and resource endowments
May affect of success and the scale of deployment.
2. Scaling out technologies:
Leverage alliances tech. dissemination and knowledge dissemination
Explore Synergies (for example traditional + radio ICTS- approaches)
Technologies with low interest from private sector
