2. Types of costs and benefits
(explicit and implicit) :
- Direct outlays (explicit)
- Partial equilibrium
- General equilibrium
- Environmental and social
Financial costs (outlays) are
the most intuitive
Eco-Efficient Agriculture for the Poor
4. After costs/benefits are identified,
then:
• Cost Benefit Analysis (CBA)
– Basis of comparison for decision-making
– Determine if a project, policy, investment is
worthwhile
OR
• Cost Effectiveness Analysis (CEA)*
– OUTCOMES
* CAE (US$/tCO2eq) Eco-Efficient Agriculture for the Poor

- First or second best
Complications:
- Constrained markets (micro-level)
- Environmental cost (externalities)
- Social cost (they ignore equity issues)

10. Identifying alternatives
• Expert workshop
• Regional workshop with local stakeholders
• Consult crop/agricultural federations
• Meet with government officials to determine
political feasibility
• Prioritize – focus on WIN-WIN alternatives
• Identify potential barriers (social, cultural,
economic)

11. Mitigation and adaptation measures
Livestock Rice
• Improved irrigation systems • Water efficiency
• Silvo- and agro-pastoral systems • Efficient use of N-fertilizers
• Testing alternatives to efficient use of N- • Clean Development Mechanism
Fertilizer project formulation
• Improved pasture • Agricultural insurance programs
• Research (focus on animal genetics) • Research (focus on biotechnology)
• Land leveling
• Improved irrigation systems

28. Some gaps…
• More programming work
– Better understanding of implication of mitigation
and adaptation measures on small farmers
• Environmental and social cost
• Links between mitigation and adaptation
