What next?What next?

•Consult with climate scientists

– Identify most likely climate scenario in the next 30

– 60 yrs at the project sites

•Consult with water resource engineers

– Identify proper alternatives for CC adaptation

– Get estimates of the costs of those alternatives


Cost-Benefit Analysis in Agriculture

The economic cost-benefit analysis of alternative rice growing technique

• Title: The economic cost-benefit analysis of alternative rice growing technique

• Objective:– To evaluate the cost and benefit of alternative of rice

growing technique at the farm level• Geographic scope of the project: – Irrigated area in central region

• Actions on the ground/Alternatives:– Broadcasting– Manual parachuting – Rice transplanters
