Central to our response to climate change, at any scale and in any form, should be an understanding vulnerability. A group is vulnerable [pdf] when it is “susceptible to, and unable to cope with, adverse effects”. Most definitions of vulnerability stress three variables:
- Exposure: the magnitude, frequency, duration, and geographical coverage of environmental pressures experienced.
- Sensitivity: the extent to which social equilibria are altered or affected by change.
- Adaptive capacity: the ability to evolve to accommodate changes in the environment and to increase the scope of the variability it can cope with.
|A Maasai in Nairobi|
The Maasai livelihood is sensitive to increasingly intense climate change. The draught has substantively reduced the area suitable for grazing cattle, forcing sedentism and diminishing the viability of maintaining livestock. In other words, the existence of pastoralism as an identity and as a livelihood strategy is under attack. Maasai are above all people-of-cattle, and it is thought that all other values originate from this central commitment. Additionally, the quantity of livestock is an important determinant of social status and wealth. Lastly, their cattle provide nutrition, as well as financial capital for food, tuition fees, and other basic necessities. Therefore, pastoralism is undermined by the decrease in natural, social, and financial capital as a consequence of changes in climate, demonstrating its sensitivity.
Finally, the adaptive capacity of individual pastoralists themselves is likely to be sufficient. The Maasai, for example, are progressively becoming educated, preparing children for employment in formal economic sectors. Alternatively, people migrate to nearby cities (e.g. Nairobi and Arusha), start agricultural cultivation, or trade in goods like charcoal and sand. However, these forms of income diversification come at the cost of a pastoral livelihood, threatening its preservation as a way of life.
Bottom line: Pastoralist livelihoods are vulnerable to climate change as its fundamental characteristics are exposed and sensitive to environmental pressures, while adaptation comes at the cost of their traditional lifestyle.
