The study assessed pulses farming as an adaptation to climate change in semi-arid areas. FGD, Household Questionnaires, Key Informant Interview and Observation were used to collect primary data from four study villages; Itigi, Ipande, Damweru and Kitopeni. A total of 106 heads of households were involved in the study through questionnaires and quantitative and qualitative data were analyzed statistically and through content analysis technique respectively. Cereals among maize, millet and sorghum have lost their economic significance among farmers while pulses including chickpea, lentils and beans are potentially currently cultivated by more farmers. Climate change effects such as shifting and shortening of rainfall season and increasing drought have contributed to the decline of cereal crop yields. Specifically shifting of rainfall season and drought interaction vitally influence the decline of cereal crop yields, F (1, 99) = 198.770, p = 0.000 and the same causes have led to the adoption of chickpea and lentils farming in the study area as shifting of rainfall season was statically significant to the adoption of pulses farming, X2 = 9.138, df = 2, p = 0.010 and drought was, X2 = 106.000, df = 3, p = 0.000 as the pulses are found adoptive drought condition and shortened rainfall season. This has enhanced food and nutrition assurance to farmers, increased household income and farmers’ livelihood.
