“…Socio-economic development and livelihood activities in most of the developing countries including East African countries are strongly affected by climate variability and change [1] [2] [3] [4] [5]. In most of the East African countries, the production and productivity in agriculture and livestock sectors are largely influenced by the availability and variability of rainfall amount of a particular season.…”

This study aimed at assessing the evolution, distribution and the socioeconomic impacts of extreme rainfall over East Africa during the March, April and May (MAM) rainfall season focusing on assessing the trends and contribution of MAM rainfall in mean annual rainfall across the region. It employed Principal Component Analysis (PCA) methods to capture the patterns and variability of MAM rainfall. The PCA results indicated that the first Principal Component (PC) describe 17% of the total variance, while the first six PCs account only 53.5% of the total variance in MAM rainfall, underscoring the complexity of rainfall forcing factors in the region. It has been observed that MAM rainfall accounts about 30%-60% of the mean annual rainfall in most parts of the region, signifying its importance in agriculture, water, energy and other socioeconomic sectors. MAM has been characterized by increasing variability with varying trend patterns across the region. The MAM rainfall trend is not homogeneous across the region; some areas are experiencing a slight decreasing rainfall trend, while other areas are experiencing a slight increasing rainfall trend. The observed trend dynamics is consistent with the global trend patterns in precipitation as depicted in recent Intergovernmental Panel on Climate Change (IPCC) reports. Over the last five years MAM rainfall season have been characterized by record-breaking extremes. On 8 th May 2017, Tanga and Mombasa meteorological stations recorded 316 mm

“…The extended lockdown in Uganda, particularly for border districts where many Indigenous populations live, has hampered their mobility to access forested areas for foraging, access to nearby communities to offer labour for food exchange, and access to agricultural fields for food production. These challenges are exacerbated by existing climate effects, 9 including recent flooding in 2019 that damaged crops, compromised food production, 10 and reduced the resilience of Indigenous populations when the COVID-19 pandemic hit.…”

“…The long period of lockdown in Uganda, particularly for border districts where many Indigenous populations live, has hampered their mobility to access forested areas for foraging, access to nearby communities to offer labor for food exchange, and access to agricultural fields for food production. These challenges are exacerbated by existing climate effects [54], including recent flooding in 2019 that damaged crops, compromised food production [55] and reduced the resilience of Indigenous populations when the COVID-19 pandemic hit. Climate change challenges impact the resilience of indigenous food systems with direct and immediate repercussions for the health and nutrition of local populations [56].…”

Background: Agriculture represents the cornerstone of Africa’s economy and accounts for the majority of livelihoods across the continent. Therefore, African countries economy is highly exposed for climate change impacts. Countries with low-middle income are highly affected by extreme weather and climate events and are often overrepresented in the number of individuals displaced by these events. On the other hand, the poorest continent, Africa with the most vulnerable populations to infectious diseases, is predicted to be significantly affected by the ongoing COVID-19 outbreak. Currently there are no studies in the literature addressing the synergistic impact of climate change and COVID-19 on gut health in Africa. The African Middle East Association of Gastroenterology (AMAGE) and the Clinical Research Committee of the World Gastroenterology Organization (WGO) had established a joint research group called Climate change in Africa Group (CCAG) to study this point. Aim of the Work: The aim of the current review is to study the synergetic impact of both climate change and COVID-19 pandemic on gut health in Africa. Conclusion: Climate change events lead to planned and unplanned migrations with emerging new zoonotic disease due to increased exposure of humans to animals. Drastic overwhelming global events carry the risk of water scarcity, food insecurity and population gathering in camps which may increase the prevalence of water-born , food-born and vector-borne diseases. The low-middle income countries are highly affected by extreme weather and climate events and are often over represented in the number of individuals displaced by these events. Africa with the most vulnerable populations to infectious diseases is predicted to be significantly affected by the ongoing COVID-19 pandemic.
