Assessing agroforestry practices and soil and water conservation for climate change adaptation in Kenya: A cost-benefit analysis

The study was carried out under the Integrating Agricultural Sectors into National Adaptation Plans programme, with the aim of capacity building, generating evidence-based results for selecting adaptation options, and informing adaptation policy dialogues on adaptation in agriculture. This study analyses the economic worthiness of adaptation measures currently being practiced by some farmers on their land. It uses cost-benefit analysis (CBA), which is recommended by the Least Developed Countries Expert Group as one of the methodologies to be used in the preparatory stages of the NAPs to rank and prioritize adaptation options according to their costs and benefits to society.

Analytical results show that the climate change adaptation measures analysed are financially and economically profitable. However, profitability varies by the agro-potential of the area: adaptation options are most profitable in high potential areas, even if the opportunity cost may be highest in those areas. Results are stable and do not vary when discount rates and yield changes change.
