Climate Trends and Farmers’ Perceptions of Climate Change in Zambia (original) (raw)

Abstract

A number of studies use meteorological records to analyze climate trends and assess the impact of climate change on agricultural yields. While these provide quantitative evidence on climate trends and the likely effects thereof, they incorporate limited qualitative analysis of farmers’ perceptions of climate change and/or variability. The present study builds on the quantitative methods used elsewhere to analyze climate trends, and in addition compares local narratives of climate change with evidence found in meteorological records in Zambia. Farmers offer remarkably consistent reports of a rainy season that is growing shorter and less predictable. For some climate parameters—notably, rising average temperature—there is a clear overlap between farmers’ observations and patterns found in the meteorological records. However, the data do not support the perception that the rainy season used to begin earlier, and we generally do not detect a reported increase in the frequency of dry spells. Several explanations for these discrepancies are offered. Further, we provide policy recommendations to help farmers adapt to climate change/variability, as well as suggestions to shape future climate change policies, programs, and research in developing countries.

Notes

  1. An exception is the study by Nyanga et al. (2011), which examines farmers’ perceptions of climate change in Zambia and provides useful insight into some of the adaptation strategies that farmers employ. However, their study relies solely on farmers’ accounts of weather changes and does not interrogate these against meteorological data. Furthermore, it focused narrowly on conservation agriculture as a response to climate change, and this emphasis likely obscures other elements of the farmers’ experiences of, and adaptions to, climate change.
  2. Agro-ecological region II is further divided into IIA and IIB, a division that is based on differences in soil type and rainfall (with sandier soils and less rainfall in IIB). As just 7–8 % of the population of rural Zambia reside in region IIB in the west (CSO/MAL/IAPRI 2012; Thurlow et al. 2008), our analysis is focuses on the eastern portion of the region (IIA).
  3. Chipata meteorological station has 1.78 % missing rainfall observations and 10.13 % missing temperature observations. For Choma these values are 0.14 % (rainfall) and 11.20 % (temperature), and for Mbala these values are 0.33 % (rainfall) and 21.77 % (temperature).
  4. This paper reports τ b. The MK tau can be understood as the degree to which the climate variable and year are related, with values larger in absolute magnitude indicating a stronger association.
