Africa Adapts


Sub-Saharan Africa is considered to be especially vulnerable to the affects of climate change, with the indigenous tribes of this region being particularly defenseless.  The complete dependence on agricultural production, limited adaptive capacity and comparatively poor health outcomes exhibited here place these communities at the greatest risk.

A paper by Schlenker and Lobell, 2010 suggests that staple crops such as maize, sorghum, millet, groundnut and cassava are expected to decrease in yield by somewhere between 8% and 22% by 2050 if the median temperature of Africa rises between the expected amount of 3°C to 4°C!  These consequences are somewhat exacerbated in countries such as Kenya, where the poverty rate is at a staggering 52% and 73% of the labor force relies on agricultural production for their livelihood.
On national scales strategies such as irrigation systems, disaster relief, insurance and cohesive policies to reduce livelihood risks should be adopted.  However, considering the current political instability of Africa, relying on near future implementation of policies such as these would not be wise. Adjustments at the farm household and community scale is a more reasonable and achievable approach, where significant improvements can be made in order to help communities to adapt to climate change.
Actual perception of climate change within these communities may be a much larger factor than previously thought.  Do farmers think it necessary to adapt? The behavior of farmers’ depends more on their perceptions of climate change and climate risk, rather than climate patterns as measured by scientific methods.
A household survey conducted in 2011 indicated that that farmers adopted a range of practices in response to perceived climate change. The most common responses included changing crop variety (33 %), changing planting dates (20 %), and changing crop type (18 %). Other responses included planting trees (9 %), decreasing the number of livestock (7 %), diversifying, changing, or supplementing livestock feeds (7 %), changing fertilizer application (7 %), and soil and water conservation practices (5 %).
This Report looks into how other indigenous communities are adopting strategies for adaptation in the face of climate change, with a focus on Namibia.

  1. Another interesting post Stephanie. I was just wondering if you could explain what you mean when you said that the behaviour of the farmers depends more on their perception of climate change, than actual climate patterns? Do you mean the fear of the potential threat to their livelihood will make people look for new techniques and farming practices?
