It is hard to imagine that something as simple as cow poop can change society, but that’s the key message Rotarian Jamie Kyles shared with the Rotary Club of Kingston.


Because local subsistence farmers didn’t cooperate, Kyles knew something they didn’t. There were among them a couple of growers whose coffee plants yields were 3 or 4 times greater than the average yield of 2 kg per plant.
Using that knowledge and Rotary donations Jamie developed a four-pronged approach:
- Buy and truck in lots of manure
- Supply hand tools to process the manure
- Get pruning tools for the coffee bushes
- Build raised drying beds for the coffee

Without the project, the value of the coffee produced in 2019 would have been USD $154,000. With the project, the actual value was USD $347,000, or about a 500% increase.
“By the end of the second year,” Kyles said, “The farmers had gained “financial traction” and were working together and picking up 99% of the cost of continuing the project.” This he said, “Is my definition of sustainability.”
Besides the money and greater yields, Kyles listed other benefits to the community:
- A decrease of 50% in domestic violence for women,
- New roofs on many houses,
- Several orphans adopted,
- Improved nutrition and
- More children attending school.
