This report gives an insight into the construction costs of road water harvesting structures and their return on investment. In this way, it shows how farmers can benefit greatly from relatively low investment.
Kitui County is classified as semi-arid to arid, where most farmers are agro-pastoralists and rely on rainfall for farming. There is a bimodal rain pattern, however, rains are often unreliable and
insufficient. As a result, farmers face crop failures. The relevance of water harvesting, retention and storage is profound, as this can extend their growing season, allowing farmers to survive and thrive in times
In this research farmers who practice road water harvesting, were asked about how they harvest road runoff and how this helps them in their farm. Besides, information on their income was gathered and
compared with the costs of construction of road water harvesting, so to compute a cost-benefit analysis. This was done to learn about the practices of road water harvesting and on how this can
benefit the farmers and their roads and environment. On average farmers are cultivating 2-5 acres, mainly growing maize, beans, vegetables and fruits.
