Variable used in the simulation model to calculate the NPV of the Net Benefits associated with the CSA practices.

Variables	Attribute	Explanation
Implementation cost	Random	The implementation cost is considered random to capture the variability in production technologies among farmers in the area of study
Maintenance cost	Random	The maintenance cost is considered random to capture the variability in production technologies among farmers in the area of study
Yield price associated with crops (cereals, legumes and vegetables) and livestock (cattle, sheep and goats)	Non-random	Based on the information collected via the household survey, the variation of crop prices per unit had very minimal variation across the farms
The response of yield from the crop (cereals, legumes and vegetables) and livestock (cattle, sheep and goats)	Random	The yield associated with different crops vary across farms and this variation is determined largely by the impact that the adopted CSA have on different crops. It was considered random to capture the large degree of uncertainty around its true value
Practice lifespan, time for physical response parameters (t1 and t2) and the discount rate.	Non-random	The lifespan associated with the CSA practices being studied was provided by the attribute of the practice itself and is therefore nonrandom.
