It is in this southern zone that the greater part of the population, both nomadic and settled, is concentrated.
However, the population of Afghanistan is difficult to quantify because there are both nomadic and semi-nomadic populations (Kuchis), and the nomadic population is approximately 20%% of the total population.
This is because both nomadic and transhumant pastoralism are successful adaptations for survival within highly variable environments (Niamir-Fuller 1999; Khazanov 1994; Salzman 2004; Cummins 2009).
Species were categorised by movement life history (nomadic (n = 25), sedentary (n = 54), partially migratory (n = 59), and species that were both nomadic and sedentary (n = 19)) according to the literature [15], [67], [68], [69], [70], [71], [72].
Due to the blurred boundaries between movement categories [25], [38], [73], we only used species that could be reliably characterized as nomadic, sedentary, both nomadic and sedentary, or partially migratory in the movement comparisons; very few species within this assemblage could be classified as true migrants and therefore were not the focus of this study.
We screened 2.5 million single nucleotide polymorphisms in 161 individuals from 13 Sahelian populations, which together with published data cover Western, Central, and Eastern Sahel, and include both nomadic and sedentary groups.
Alternate with both feet and repeat.
Train both legs and repeat everyday.
Majority of respondents in both nomadic (64%) and semi nomadic (63%) land-use sites noted presence of a range management system in their area and only 46% in the sedentary land-use area.
The answers to these questions would have allowed a more detailed analysis of mobile pastoralism both in households classified as nomadic and those as sedentary.
