... Prosopis juliflora is an invasive alien leguminous tree introduced as a way of combating desertification, deforestation, and improving soil fertility. Over time, the tree has reported significant negative externalities to farmers. Different strategies such as management through utilization and complete eradication have been proposed to reduce these externalities. We investigate the various factors ...

Abstract:
... Labeo victorianus (Boulenger, 1901) is one of the endemic fishes in Lake Victoria Basin (LVB) but is now threatened by multiple stressors caused by human activities. We investigated spatial and temporal variability in food composition and condition of L. victorianus in influent rivers of Lake Victoria, Kenya. Sampling was done during the dry and wet seasons by electrofishing. Food composition anal ...
... Restrictive abortion laws resulting in unsafe abortions form one of the key causes of maternal morbidity and mortality in Kenya. Despite the existence of several Women's Rights Organisations (WROs), advocacy for safe abortions against restrictive laws does not have the momentum the subject deserves. This research draws on agenda-setting literature to explore factors that impede advocacy initiative ...

Abstract:
... The recent proliferation of mobile phones in rural Africa has also led to increased interest in mobile financial services (MFS), such as mobile money and mobile banking. Such services are often portrayed as promising tools to improve agricultural finance, especially among smallholders who are typically underserved by traditional banks. However, empirical evidence on the actual use of MFS for agric ...

Abstract:
... Social influence impacts individuals’ behavior through norms – the perceived appropriateness of behaviors – and social referents, whose behavior is copied by others. Interventions using social influence may help promote conservation-friendly behaviors. We explored how perceptions are influenced by descriptive norms (what people do) and social referents (who does it) in relation to livestock manage ...

Abstract:
... The mechanisms influencing livestock pricing in Kenya are well studied. The determinants of quality-based payments on markets in conflict-affected areas, however, are hardly documented. In this paper, we offer a deeper understanding of transitions towards quality-based payments from the perspective of livestock buyers in the Kerio-Valley, Kenya. The location is known for protracted communal confli ...

Abstract:
... The contribution of seasonality in species communities to elevational diversity of tropical insects remains poorly understood. We here assessed seasonal patterns and drivers of bee diversity in the Eastern Afromontane Biodiversity Hotspot, Kenya, to understand the contribution of seasonality to elevational biodiversity patterns. Bee species and plant species visited by bees were recorded on 50 stu ...

Abstract:
... Women have made notable political gains globally, evidenced by the number of elected women. In Kenya, though the current number of elected women in parliament, senate and governor position is the highest it has ever been, women contestants still face a number of challenges during their political campaigns. To strategically position themselves during campaigns, women have to use slogans that appeal ...

Abstract:
... Promoting human-wildlife coexistence is one of the most complex and pressing global conservation challenges faced today, particularly for large carnivore species. Effective conservation of large carnivores rests on interventions fostering coexistence in human-dominated landscapes, across the large ranges on which they depend. However, there is a paucity of research evaluating such interventions, a ...

Abstract:
... Fall armyworm (FAW), Spodoptera frugiperda J.E Smith, (Lepidoptera: Noctuidae) is a serious invasive pest of maize that has been established in Kenya since 2016. Little is known about its co-occurrence with resident stemborers, relative infestation and damage and how agronomic factors influence its infestation and damage in maize cropping systems across different agro-ecological zones. This study ...

Abstract:
... East Africa has experienced a number of devastating droughts in recent decades, including the 2010/2011 drought. The National Drought Management Authority in Kenya relies on real-time information from MODIS satellites to monitor and respond to emerging drought conditions in the arid and semi-arid lands of Kenya. Providing accurate and timely information on vegetation conditions and health—and its ...

Abstract:
... Maasai and other Maa-speaking pastoralists in Kenya and Tanzania have a risk-pooling system that they refer to by their word for the umbilical cord (osotua). Gifts from one osotua partner to another are contingent on the recipient’s need and do not create any debt. We refer to such gifts as need-based transfers. Maa-speakers also have a system of debt-based transfers (esile) in which gifts must be ...

We found and genetically described two novel SARS-like coronaviruses in feces and oral swabs of the greater (R. ferrumequinum) and the lesser (R. hipposideros) horseshoe bats in southern regions of Russia. The viruses, named Khosta-1 and Khosta-2, together with related viruses from Bulgaria and Kenya, form a separate phylogenetic lineage. We found evidence of recombination events in the evolutiona ...

Abstract:
... Several alphaviruses, such as chikungunya (CHIKV) and Onyong-nyong (ONNV), are endemic in Kenya and often cause outbreaks in different parts of the country. We assessed the seroprevalence of alphaviruses in patients with acute febrile illness in two geographically distant areas in Kenya with no previous record of alphavirus outbreaks. Blood samples were collected from febrile patients in health fa ...

Abstract:
... Knowledge of design peak flow is crucial in various hydrology, hydraulics, and water resources management applications. However, obtaining design peak flow is challenging, especially in ungauged basins lacking discharge observations, a circumstance that does not allow the calibration of advanced hydrological models. Recently, a new method called EBA4SUB (event-based approach for small and ungauged ...
