Resumen
Rice yellow mottle virus (RYMV) of the genus Sobemovirus is a major biotic constraint to rice production in Africa. First reported in Kenya in 1966, RYMV was later found in most countries in Africa where rice (Oryza sativa) is grown (2). During July 2000, plants with leaf yellowing and mottling symptoms were observed in Uganda in a subsistence rice field northeast of Lake Victoria, close to the Nile River. RYMV was detected by using enzyme-linked immunosorbent assay with polyclonal RYMV antisera (1) in the four samples collected. Discriminant monoclonal antibodies revealed that the samples contained RYMV serotype 4, a serotype found in eastern Africa (Madagascar, Kenya, and Tanzania) (2). The 720-nt long coat protein gene of two isolates was amplified by reverse transcriptase-polymerase chain reaction and sequenced (1). The two Ugandan isolates had 99% nt sequence identity (EMBL Accession Nos. AM114523 and AM114524). They belonged to a monophyletic group (97% nt identity) containing isolates from eastern Kenya and northern Tanzania (close to the Lake Victoria). These form a sister group (93% identity) of isolates from Lake Malawi Region in western Tanzania and are more distantly related (88% identity) to the basal strains from eastern Tanzania (2). Isolation of the Lake Victoria Region from the rest of the Tanzania by distance, physical barriers, and patchy rice cultivation explains the specificity of the strain. Year-round growth of wild and cultivated rice around the lake ensures host continuity in time and space that facilitates spread that accounts for the homogeneity of the isolates of this area. Knowledge of the presence of RYMV in Uganda is important since rice cultivation is intensified in this country and is planned in neighboring southern Sudan. References: (1) A. Pinel et al. Arch.

Resumen
History embraces the story of the Supreme Being, humanity, and the Universe. Human history is a silent realm that encompasses creation, fall, concupiscence, and the need for the prophetic voice towards human redemption. This article seeks to examine the Mwea Irrigation Scheme and explore the oppressive situation that was experienced by its rice farmers; and eventually assess the need for prophetic voice as the critical pillar and/or the key tool that ought to have stood as the weapon of addressing the vice. To this end, this article will methodologically draw from the history of Mwea Irrigation Scheme, unfold the origin and growth, the oppression of the rice farmers, and the need for the prophetic voice as the aforesaid tool of empowerment, as it seeks to build on a Kenyan version of liberation and/or political theology. Strictly therefore, the problem that this article wrestles with is the unearthing of the above-mentioned oppression of the Mwea rice farmers and the need for redemptive prophetic voice that is geared towards the ultimate goal, the liberation of the socio-economically oppressed rice farmers. Arguably, working out a liberation theology that addresses the Mwea case compares well with the Asian theologies such as the Burakumin theology for the marginalised and minority peoples of Asia whose reflection from the prophetic role of religion gives solace to their plight. It also compares with the Waterbuffalo theology, as propounded by Kosuko Koyama. In Waterbuffalo theology, a Japanese theologian, Kosuko Koyama, attempts to translate the Christian faith into the Asian tradition in Thailand, a phenomenon where farmers spend substantial amount of time in their respective rice fields without any substantial and/or decent returns. Apart from a theo-historical design, the methodology in this presentation includes: interview schedules, literature review of relevant and existing literature, and the reliance on the modus operandi that is well captured by the biblical Prophet Amos.

Resumen
Effects of change in weather conditions on the yields of Basmati 370 and IR 2793-80-1 cultivated under System of Rice Intensification (SRI) in Mwea and Western Kenya irrigation schemes were assessed through sensitivity analysis using the Ceres rice model v 4.5 of the DSSAT modeling system. Genetic coefficients were determined using 2010 experimental data. The model was validated using rice growth and development data during the 2011 cropping season. Two SRI farmers were selected randomly from each irrigation scheme and their farms were used as research fields. Daily maximum and minimum temperatures and precipitation were collected from the weather station in each of the irrigation schemes while daily solar radiation was generated using weatherman in the DSSAT shell. The study revealed that increase in both maximum and minimum temperatures affects Basmati 370 and IR 2793-80-1 grain yield under SRI. Increase in atmospheric CO2concentration led to an increase in grain yield for both Basmati and IR 2793-80-1 under SRI and increase in solar radiation also had an increasing impact on both Basmati 370 and IR 2793-80-1 grain yield. The results of the study therefore show that weather conditions in Kenya affect rice yield under SRI and should be taken into consideration to improve food security.

Resumen
Background: Glycemic index (GI) measures postprandial blood sugar after consumption of carbohydrate-rich foodstuff. Kenya is yet to fully embrace this concept in prevention and management of diabetes mellitus. Objective: To review and tabulate GIs of locally consumed foods in order to improve dietary management of diabetes mellitus. Methodology: A literature search was conducted using Google scholar and PubMed databases which identified 7 articles on glycemic index values of Kenyan foods published between 2002 and 2020. Two articles failed to meet the inclusion criteria and five proceeded for review. Key search words used included GI, glycemic load and glycemic response combined with Kenya. The data was reported depending on whether the testing involved healthy individuals or patients suffering from diabetes mellitus. Results: Nine individual foods and 7 mixed meals were identified. Low GI foods included beans and whole maize ugali consumed alongside cowpea leaves. High GI foods included whole maize ugali eaten with beef, boiled rice, boiled cassava and cassava-sorghum ugali eaten with silver fish. Conclusion: Proper meal mixing is important in diabetes management. Cowpea leaves and beans possess GI lowering po- tential. This information can be used to improve guidance on food choices for diabetes patients. Keywords: Glycemic index; glycemic load and glycemic response; Kenya.

Resumen
From the perspective of national food security, strengthening domestic rice production is an urgent issue for Kenya. For this purpose, it is helpful to consider varieties that generate novel and competitive values different from those of conventional varieties. Recently, domestic japonica rice, which is now being distributed, has become an attractive variety with a high market price and its production is expected to increase. Although it is competitive and promising as a crop for small-scale farmers, the production stage costs and benefits are not clear. Thus, a study was conducted to perform a cost–benefit analysis of japonica rice in comparison to conventional rice at the production stage and evaluate strategies for strengthening the domestic production of rice. We conducted an experimental cultivation of japonica rice in the Mwea region, Kenya, where japonica rice is produced. As a result, although production costs for japonica rice are higher than costs for conventional varieties (24.46 KSh/kg versus 22.63 KSh/kg), when a high-yielding variety is grown (6.44 tons/ha for japonica rice compared to 6.07 tons/ha for conventional rice), a larger net profit can be obtained (65.54 KSh/kg versus 32.37 KSh/kg). We believe that initiatives to improve difficulties at the production stage would make the production of both japonica rice and conventional rice more economically viable and facilitate strengthening of the overall domestic rice production.

Resumen
The inefficient water use, and variable and low productivity in Kenyan public irrigation schemes is a major concern. It is, therefore, necessary to periodically monitor and evaluate the performance of public irrigation schemes. This prompted evaluation of performance of three rice growing irrigation schemes in western Kenya using benchmarking and principal component analysis. The aim of the study was to quantify and rank the performance of selected irrigation schemes. The performance of the irrigation schemes was evaluated for the period from 2012 to 2016 using eleven performance indicators under agricultural productivity, water supply and financial performance categories. The performance indicators were weighted using principal component analysis and combined to form a single performance score using linear aggregation method. The average performance in the Ahero, West Kano and Bunyala irrigation schemes was 48%, 49% and 56%, respectively. Based on performance score, the Bunyala irrigation scheme is the highest performing rice irrigation scheme in western Kenya. The three irrigation schemes have an average performance. Operation and management measures to improve the current performance of the irrigation schemes are needed.

Resumen
Multiple mycotoxins were tested in milled rice samples (n = 200) from traders at different milling points within the Mwea Irrigation Scheme in Kenya. Traders provided the names of the cultivar, village where paddy was cultivated, sampling locality, miller, and month of paddy harvest between 2018 and 2019. Aflatoxin, citrinin, fumonisin, ochratoxin A, diacetoxyscirpenol, T2, HT2, and sterigmatocystin were analyzed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS). Deoxynivalenol was tested using enzyme-linked immunosorbent assay (ELISA). Mycotoxins occurred in ranges and frequencies in the following order: sterigmatocystin (0–7 ppb; 74.5%), aflatoxin (0–993 ppb; 55.5%), citrinin (0–9 ppb; 55.5%), ochratoxin A (0–110 ppb; 30%), fumonisin (0–76 ppb; 26%), diacetoxyscirpenol (0–24 ppb; 20.5%), and combined HT2 + T2 (0–62 ppb; 14.5%), and deoxynivalenol was detected in only one sample at 510 ppb. Overall, low amounts of toxins were observed in rice with a low frequency of samples above the regulatory limits for aflatoxin, 13.5%; ochratoxin A, 6%; and HT2 + T2, 0.5%. The maximum co-contamination was for 3.5% samples with six toxins in different combinations. The rice cultivar, paddy environment, time of harvest, and millers influenced the occurrence of different mycotoxins. There is a need to establish integrated approaches for the mitigation of mycotoxin accumulation in the Kenyan rice.

Resumen
Rice blast disease is caused by the ascomycete fungus Magnaporthe oryzae and is of economic importance worldwide, due to its wide geographical distribution and the severe yield losses it causes on cultivated rice. Understanding the population structure of M. oryzae is key to sustainable management of blast disease. In this study, a total of 290 M. oryzae isolates were collected from rice growing regions in Kenya including Central Kenya (Mwea irrigation scheme), Western Kenya (Ahero and Maugo irrigation schemes in Ahero and Homa-Bay respectively) and Coastal Kenya (Kwale). Initially, I undertook genotyping of a subset of Kenyan isolates by DNA sequence analysis of the internal transcribed spacer regions (ITS 1 and ITS 2) of the rRNA-encoding gene unit and by DNA fingerprinting using the Pot2 repetitive DNA element. Phylogenetic analyses based on ITS sequences clustered together isolates from Western and Coastal Kenya which were distinct from Central Kenya isolates. Cluster analysis based on 80% DNA fingerprint similarity, identified five clonal lineages designated KL1, KL2, KL3, KL4 and KL5 with most isolates belonging to lineages KL2, KL3, KL4. The clustering of isolates was region specific with Western and Coastal isolates closely related to each other and distinct from Central Kenya isolates. Distribution of mating type gene loci (MAT1.1 and MAT1.2) was determined using mating type gene specific primers. My results indicate that MAT1.1 is the predominant mating type and is distributed in all the rice growing regions of Kenya. MAT1.2 isolates were identified only in Coastal Kenya. I further undertook high throughput next-generation DNA sequencing of the genomes of 27 M. oryzae isolates from sub-Saharan Africa (SSA), including Kenya, Uganda, Tanzania, Benin, Togo, Nigeria and Burkina Faso and compared them to other sequenced strains from China, India, USA, Philippines, Thailand, Korea, Japan, France and French Guiana. Single nucleotide polymorphisms (SNPs) indicated that majority of East African isolates of M. oryzae clustered separately from West African isolates. African isolates clustered with isolates from India and China, indicating that rice blast in SSA may have originated from Asia. Pathotype analysis of Kenyan isolates was undertaken using a set of monogenic differential rice varieties, collectively harbouring 24 disease resistance genes. Rice blast resistance gene Pi-z5 conferred resistance to all the isolates tested. Other resistance genes that conferred resistance to majority of isolates tested include Pi-9, Pi-12(t), Pi-ta, Pi-ta2 and Pi-z. These resistance genes are suitable candidates for introgressing into commercially grown varieties in Kenya in combinations. I also investigated the population of M. oryzae isolates to identify cognate avirulence gene loci, including novel genes not yet reported. Finally, I evaluated rice varieties grown in Kenya for resistance to indigenous rice blast isolates under laboratory conditions. Rice variety Basmati 370 was susceptible to rice blast with varieties IR2793-80-1, BW 196, NERICA 1, NERICA 4, NERICA 10, and NERICA 11 showing some disease resistance. Varieties ITA 310 and Duorado Precoce were moderately tolerant to rice blast. This information is being used to develop a durable blast resistance strategy in sub-Saharan Africa.

Resumen
It already seems preposterous to be able to sufficiently meet global food demand of the expected nine billion people by 2050 while at the same time maintain our emissions levels below 2ᵒC by the end of the century. This is more so for a continent such as Africa where much of this population is expected to arise from considering the fact that the continent is ranked to have the highest proportion of food insecure population. In order to overcome this challenge, we will need a total revolution of our agricultural production systems to systems that not only focus on increasing food production but also build our resilience to climate change. An example of one such practice is System of Rice Intensification (SRI) which is acclaimed to increase rice production while at the same time reducing the pressure on scarce water resources, minimizing agricultural greenhouse gases emissions and improving the farmers' households' adaptive capacity to climate change impacts by increasing their income. However, despite the success attributed to SRI, its uptake across Sub Saharan Africa is arguably low. This is puzzling considering the high proportion of food insecurity in the region and the region's susceptibility to damage from increased severity and frequency of climate extreme events such as droughts and floods due to its geographical positioning and the limited adaptive capacity of its people. In this work, the researcher sought to understand the barriers and enablers to the adoption of the System of Rice intensification in Mwea irrigation scheme (MIS) in Kenya. The findings show that most barriers to the uptake of SRI in MIS occur during the dissemination of SRI. Further critical barriers to the uptake of SRI in MIS were identified as follows: lack of formal SRI training, high costs of rice production, failure to involve key stakeholder institutions such as SACCOs while marketing SRI and farmer's age. Moreover, the study also depicted that most barriers to SRI adoption were intertwined, thus focusing on a single barrier would be myopic. Furthermore, enablers to the uptake of SRI in MIS are tied to the benefits of SRI pre-empted by lead farmers. This correlation implies that the benefits of SRI are key motivators for SRI adoption. Other enablers include training. However, informal training on SRI through social networks which play a crucial role at disseminating climate adaptation activities amongst small scale farmers, is marked with a lot of inconsistencies which makes it a barrier for SRI uptake. In this regard, we advise that SRI trainers clearly highlight the activities involved in SRI and their resultant benefits during initial SRI information dissemination.

Resumen
この論文は、ケニアの選挙後の暴力の年表に焦点を当てています。それがどのように始まり、頂点に達し、減少、そして再発を探ります。ケニアで2008年に創設された真実、正義、和解委員会は、独立後35年間の過去の人権不正と不正行為を文書化に行なった。複数の要因が組み合わされ、複数政党の大統領選挙で暴力を引き起こします。政府が問題の一部であるため、委員会による良心的な最終報告書と勧告は保留中です。
This thesis focuses on the chronology of post-election violence in Kenya. It explores how it started, peaked, faded, and returned. The Truth, Justice, and Reconciliation Commission created in 2008 in Kenya documents 35 years of past human rights injustices and malpractices from independence in 1963. Multiple factors combine and trigger violence in multiparty presidential elections. The conscientious final reports and recommendations by the Commission remain in limbo as the government is part of the problem. Unequally shared land resources and a grave presidential contest cause post-election violence. Empowering the Supreme Court is a necessity for fair justice.

This thesis analyzes recent trends of transnational terrorism in East Africa. It assesses the background of domestic and international terrorist attacks in the region from 1998 to 2012. The study then quantitatively analyzes regional trends, using data drawn from the Global Terrorism Database (GTD) showing dramatic increases in levels of terrorist violence from terrorist organizations like Al-Shabaab. Based on Al-Shabaab’s propaganda, conventional wisdom suggests that the recent increase in transnational terrorism in East Africa is attributable to Al-Shabaab’s retaliation for countries’ troop contributions to the African Union Mission in Somalia (AMISOM). In contrast, the analysis presented here is based on the hypothesis that a causal relationship exists between large flows of Somali refugees and increases in terrorist violence. Evidence shows that Al Shabaab operatives disguise themselves as refugees to cross borders and evade detection. Refugee populations are used as sources of recruitment and as safe havens for planning and executing terrorist attacks, particularly in Kenya. Recommendations include: (1) intensification of information operations and human intelligence efforts, (2) strengthening of the Joint Counter Terrorism Center by establishing strategies for deterrence and disruption of transnational terror networks, and (3) coordination of regional actions for countering terrorist threats attributed to Somali refugee communities.

Resumen
AbstractClimate variability is one of the leading natural threats and a root cause of food insecurity in the developing world, more so in Africa. It is a major impediment to the accomplishment of the global Sustainable Development Goals (SDGs), Vision 2030 and Big Four agenda in the Kenyan context. The rise in occurrence and brutality of extreme events resulting from variability of climate including prolonged flooding and drought has become more pronounced in the relatively drier areas. This chapter presents a synthesis about rural communities in Garissa and Tana River Counties, Kenya. The key environmental conditions that face the rural communities in the two counties are prolonged drought and recurrent flooding events. The two conditions have resulted in various challenges facing the communities in these regions through low agricultural production (food and pastures), poor infrastructure, human displacement, and the resultant extreme poverty, overall food insecurity, and tough livelihoods. The problems have been exacerbated by lack of capacity by most of the community members to cushion themselves against these impacts. However, as the conditions continue to manifest themselves, the community members have also identified adaptive mechanisms that are best suited in the region including planting drought-resistant crop varieties, diversifying their livelihoods, embrace sustainable land use, and made efforts to plant trees. We, therefore, conclude that integrated information sharing including early warning alongside affordable and appropriate technologies and crop insurance could be an entry point in cushioning the local communities in the arid and semiarid lands (ASALs) against the extreme weather conditions experienced in the region.

Resumen
AbstractKenya is among the world’s most vulnerable countries to climate change-related stresses and extreme events. According to FAO, over 75% of the country is classified as arid and semiarid with rainfall availability and amounts quite unevenly spread across the different parts of the country. The country has very skewed distribution of water sources with the western area being relatively well endowed with abundant water resources. The exponential growth in the country’s population over the years, together with rapid environmental degradation and poor water resource development programs, have worsened the country’s vulnerability to the effects of climate change. Ethnic conflicts over land resources are common-place in Kenya’s rural areas where majority of the people live and the effects of extreme climate change events are likely to exacerbate resource-based conflicts. In this chapter we explore the extent of climate change-induced resource conflicts in three counties along rainfall availability gradient, namely, Kiambu County which experiences relatively high rainfall and also high urban population, Machakos County, which generally experiences modest rainfall availability, and Makueni County regarded to be one of the most arid and semiarid counties in the country. Data were collected in 2017 using a closed ended questionnaire. Between-subjects MANOVA design was used to examine relationship between independent and dependent variables. Qualitative results of the open-ended question reveal that climate change impacts can be diverse, particularly for vulnerable regions such as arid and semiarid regions such as Makueni County. In this county, respondents mentioned nine ways climate change had impacted communities, with the most frequently mentioned impact being increasing food insecurity followed by increasing water shortages. Machakos followed with seven impacts mentioned starting with increased water shortages followed by scarcity of pasture. In Kiambu County, only four impacts were mentioned with food insecurity being frequently mentioned among the list of impacts of climate change in the county. Results of the descriptive and inferential statistics reveal that resource-based conflicts vary along the hydrological gradient. In Machakos County, resource-based conflicts are perceived to have risen during the last 5 years (M = 3.92, SD = 0.66), followed by Makueni (M = 4.10, SD = 0.670). Kiambu residents do not consider resource-based conflicts to have risen during the last 5 year, (M = 2.50, SD = 1.38). Differences in severity of climate related conflicts are statistically significant, F2, 76 = 12.78, p <0.01. Also, climate change is strongly perceived to be a factor in the rise of resource-based conflicts in Machakos County (M = 4.10, SD = 0.67). In Makueni County as well, climate change is perceived to be a significant contributor to resource-based conflicts (M = 3.98, SD = 1.70). These findings have relevance on county and national policies targeted to build capacity to cope with climate change induced resource-based conflicts among grassroot communities in Kenya.

Resumen
Kenya experiences huge production-consumption deficit in relation to rice. This is due to changing eating habits that has adopted more rice in the menu and rapidly rising population. Rice production has remained low being unable to meet consumption. Rice ecosystems in Kenya include irrigated, rainfed lowland and rainfed upland. Irrigated ecosystem has over the years been given more emphasis despite rainfed rice farming having double the potential over irrigation system. Ecologically rice grows well in abundant water supply, warm to high temperatures and in Clay sandy to loamy soils with slightly acidic to neutral pH. Rice varieties grown in Kenya are mainly traditional, introduced improved, hybrids and landraces. Rainfed rice farming faces constraint’s key among them being; drought and erratic rainfall, weeds, pest and diseases, cheap imports, land ownership and poor infrastructure. Mitigating against drought and erratic rainfall, improving farm inputs and equipment, increasing germplasm production and distribution, credit support and marketing to farmers, improving farmers skills through technological transfers and infrastructural development are prospects that if adopted could increase rainfed rice productivity. More attention towards improvement of rainfed rice farming could greatly contribute to bridging the production-consumption deficit that is bridged through imports. It is with this, that this review updates our understanding of rain fed rice farming in Kenya in terms of ecological conditions, ecological systems, varieties, constraints and prospects.

Resumen
This chapter examines nonviolence as conflict resolution method in Kenya, and postulates that the advantages presented by nonviolence stand to help society overcome the trappings presented by violence. The author explores the idea of violence as laid out in the narrative and structure of the Kenyan society, the plausible reasons that gives rise to violence as a way of agitation for perceived rights and freedoms, and resolving conflicts.This chapter has focused on the history of Kenya with respect to the aspirations that existed during the time of clamor for independence and how the inability to make those dreams a reality curtailed the dreams, hopes, and aspirations of many who fought for independence and therefore creating a disenfranchised population, and above all, planting seeds of violence. This chapter observes that economic empowerment is a necessary tool to inculcate the theme of nonviolence in society. The author suggests using activities such as soccer and other related sports to create ambassadors and warriors for nonviolence.

Resumen
[This Proceedings paper was revised and published in the 2019 issue of the journal Issues in Informing Science and Information Technology, Volume 16] Aim/Purpose: This study aims to answer the research question titled What are the competencies required for the Business Process Analyst (BPA) role in organizations with ERP systems in Kenya. Through 4 hypotheses, this study focuses on two specific aspects: (1) Enhancing BPM Maturity and (2) ERP implementation. Background: The emergence of complex systems and complex processes in organizations in Kenya has given rise to the need to understand the BPM domain as well as a need to analyze the new roles within organizational environments that drive BPM initiatives. The most notable role in this domain is the BPA. Furthermore, many organizations in Kenya and across Africa are making significant investments in ERP systems. Organizations, therefore, need to understand the BPA role for ERP systems implementation projects. Methodology: This study uses a sequential mixed methods approach analyzing quantitative survey data followed by the analysis of qualitative interview data. Contribution: The main contribution of this study is a description of competencies that are critical for the BPA in Kenya both in terms of enhancing BPM maturity and for driving ERP systems implementations. In addition, this study sheds light on critical BPA competencies that are perceived to be undervalued in the Kenyan context. Findings: Findings show that business process orchestration competencies are important for driving BPM maturity and for ERP systems implementations. This study found that business process elicitation, business analysis, business process improvement and a holistic overview of business thinking are often overlooked as critical competencies for BPAs but are nevertheless critical for building the BPA practitioner. Recommendations for Practitioners: From this study, practitioners such as top managers and BPAs can be enlightened on the specific competencies that require focus when carrying out BPM and when implementing ERP systems projects. Future Research: The next step is to investigate the interventions that organizations implement to build their BPA competencies. The main aim of this would be to describe those interventions that impact the requisite BPA competencies especially those competencies that were seen to be undervalued within the Kenyan context.
