Smallholder adaptation strategies are more autonomous

The adaptation strategies employed are at sub-optimal levels i.e. MB ≠ MC

Growth of the Kenya’s economy correlates to growth and development in agriculture

Smallholder farmers provide 75% of the labour force and 75% of the market output produce (Alila & Atieno 2006)

However, climatic variability affects smallholders’ efforts

Smallholders invest to adapt to climate variability

Economic analysis of climate change adaptation strategies of agriculture.

Deltaic wetland ecosystem Prone to drought and floods

Farmers invest to reduce impacts of the shocks

The framework for analyzing the cost and benefit of climate change adaptation

Global mean Temperature

Cost without adaptation

Residual damage Net benefit of adaptation

Total cost of climate change after adaptation

Gross benefit of adaptation

Cost of adaptation + Residual damage

Improved investment on adaptation initiatives is needed

Increased budgetary allocations to climate change adaptation initiatives / projects(a) Investment in climate information provision(b) Research and development

Promotion of affordable agricultural credits(a) Community- Based Adaptation initiatives like ROSCAs (b) Credit guarantee systems

Incentives for conservation like PES
