Global statistics indicate that drought phenomena have been increasing in frequency, magnitude and severity over time, with developing countries increasingly becoming more vulnerable to its often-devastating impacts. One of the key sectors directly affected by this natural hazard is agriculture. Drought occurrences can be protracted and their impacts often fatal, particularly where agricultural production systems are rain-dependent. Agriculture is the mainstay of the Kenyan economy and inherent to its government’s development strategy, directly or indirectly supporting more than 75% of the forty-three million citizens’ livelihoods. However, only 20% of the land is arable with the remainder considered arid and semi-arid lands (ASALs). This study aims to analyze the spatial and temporal occurrence and distribution of agricultural drought in Kenya between the years 2002 and 2017. This study employs Moderate Resolution Imaging Spectro-radiometer (MODIS) satellite data and remote sensing techniques to analyze patterns in agricultural drought occurrence and identify possible factors responsible for distribution patterns, seeking to establish whether there has been a statistically significant change in agricultural drought severity in Kenya over the study period. A better understanding of dynamics in occurrence and distribution of agricultural droughts in Kenya is vital for mitigating impacts and fostering resilience to this natural hazard that are hypothesized to be gradually increasing in frequency and severity.
