Shifting climate zones and expanding tropical and arid climate regions across Kenya (1980–2020)

Abstract: Human-induced climate change significantly alters the spatiotemporal characteristics of climate zones, which drives agricultural land use and ecosystem change. However, the detectability of shifting climate zones and the rate and time of the changes has yet to be adequately addressed at the regional-to-local scale. We mapped and analyzed changes to temperature and precipitation across Kenya during the past four decades, and linked those changes to shifts in the geographic distribution and arrangement of climat… Show more

“…Smallholder farmers dominate the livestock sector in Kenya with three main livestock production systems: pastoral; dairying; and ranching (Cecchi et al, 2010). Additionally, agricultural and livelihood practices in Kenya are tightly linked to agro-climatic zones (ACZs), which are the delineation of landscapes into regions with relatively homogeneous and contiguous areas based on similar climate characteristics (Boitt et al 2014; Kogo et al 2021; Lawrence et al, 2023a,b; (Recha, 2019)). Primarily, the ACZs in Kenya represent a temperature gradient from alpine, to temperate, to tropical regions, and a moisture gradient from humid to arid regions (Gikonyo et al, 2018).…”

“…Seldom, the influence of climate and agricultural land use have been examined related to emerging infectious diseases in a spatially explicit way at regional scales. This is especially true for Middle East Respiratory Syndrome coronavirus (MERS-CoV) that is prevalent in dromedary camels across Kenya where climate and agricultural land-use change are conspicuous (Lawrence et al, 2023a,b).…”

“…Climate change is a major threat to Kenyan farming systems with seasonal changes in precipitation and temperature of varying severity and duration that negatively affect crop production and food security to the already vulnerable communities in the arid and semi-arid areas (Kogo et al, 2021;Lawrence et al, 2023). Further, agricultural development and livelihood practices in Kenya are tightly linked to ACZs (Recha, 2019).…”

“…Next, we assessed the distribution (mean and standard deviation) of temperature and precipitation within each respective temperature and moisture zone. We compared the distributions to similar information from the Sombroek et al (1982) ACZ map and developed discrete average ranges of both climate variables within each zone to represent the temperature and precipitation zones (Appendix B: Lawrence et al, 2023).…”
