**4. Actual adaptation actions in the Sahel**

Based on this systematic review, income diversification adaptation actions recorded the highest frequencies in the scientific peer review literature. This

is seen as they stood at a frequency of 53 or 12.8% and tailed closely by water harnessing actions which recorded a frequency of 48 or 11.5%. Adaptation actions like soil conservation, farm inputs, and planting high yielding varieties recorded 6.5%, 6.2% and 5.5% respectively (**Figure 5**, **Table 1**). From these results, we note

that emphasis is placed on employment diversification actions or on providing water harnessing options. While Kenya and Senegal recorded the highest cumulate amounts of adaptation actions with income diversification actions appearing to record the highest frequencies.
