**3. Countries and regions where adaptations are occurring in the Sahel?**

In the Sahel, climate change adaptation actions can be categorized into four main categories (**Figure 2**). These include technically based, economically based, indigenous based and socially based (**Figure 2**). A total of 414 adaptation actions were reported in 70 peer review journal articles. An analysis of the articles illustrates that Kenya had recorded the highest number of adaptation actions of about 75 or 18.1% during the period 1975 and 2015. This was followed by Senegal with 65 or 15.7% of all recorded adaptations (**Figure 3**). Even though these countries recorded the highest rates of adaptation actions, it is worth noting that the overall picture in term of adaptation actions in the Sahel appears to be generally low (**Figure 1**).

Regionally, with a frequency and percentage of about 261 or 63%, West African Sahel witnessed the highest adaptation actions as reported by the peer review literature. East Africa recorded 127 or 30.6% and therefore is the second most adapted region in the Sahel (**Figure 4**). Furthermore, it can be said that when a region has more adaptation actions, the same is said of its adaptive capacity (**Figure 1**).
