Analysis of trends of temperature and rainfall variations and tea yields from 1995 to 2019 in Kisii County, Kenya
Keywords:
climate variability, rainfall trend, tea yields, temperatures, tea farmersAbstract
The study examined the trends of temperature and rainfall variations and tea yields from 1995 to 2019 in Kisii County. The study targeted Kisii Meteorological Department, and three Kenya Tea Development Agency factories of Kisii County. Purposive sampling was used to choose tea factories and the meteorological Department. The study used document analysis was used to collect secondary data. Interview schedules were used to collect data from the field service coordinators who were key informants. Mann-Kendall (MK) test was used to detect trends of meteorological variables and tea yields. The results indicated that there was significant negative rainfall trend for January where rainfall has been decreasing at an average of 3.415 mm during the study period. Temperatures also depicted a positive trend though only trends for January and July were statistically significant (p<0.05). With regard to tea production levels, there were significant though negative trends in the months of February, March, June, July and December.
