In Sub Sahara Africa, food contamination continues to wreak havoc. In this region, ready-to-eat foods are majorly sold by street food vendors where hygiene becomes a major challenge given the inadequate supply of portable water. Large numbers of unlicensed vendors operating their businesses in hard to reach areas, mostly after-work hours, thwart the efforts by the public health inspectors to ensure safe food for the public.

Green leafy vegetables’ self-provisioning is an informal means of vegetables production with the major part of it used for own-consumption. In Kenya, self-provisioning is taking place in both urban and peri-urban areas. However, the motives of engaging in this practice, and of the choice of commodities to focus in, are not clear. Existing studies have provided mixed reasons for engaging in self-provisioning such as; economic hardships, improving household food security, source of employment, cultural reasons or leisure/hobby.

This study hypothesized that use of genetic parameters from different studies to evaluate overall genetic and economic gains of livestock breeding programmes could over and under estimate response to selection. This is because genetic parameters are affected by data sample size, environmental conditions and evaluation models. This premise was tested by deterministic simulation of breeding schemes that resemble that used in indigenous chicken in Kenya.

The greatest challenge in the agriculture is to produce more food with little water. The challenge facing tomato farmers in Njoro Sub County is the unfavourable conditions for tomato growth which includes very low rainfall during the dry periods. This therefore needs increasing tomato yield per volume of water used. However, there is limited information on water management practices, or deficit irrigation that would increase tomato crop yield and additionally improve on the tomato quality when drip irrigation is used.

The 2010 political revolutions in parts of the Middle East and North Africa also referred to as ‘the Arab Spring’ emerged into contemporary political history as a process in which ordinary citizens through their organised groups exerted decisive influence which brought down powerful governments. Studies on the impact of citizens’ influence on governments have, however, mostly associated it with democratisation, where it is mostly reduced to electioneering processes.

Since the emergence of al-Shabaab in 2006, radicalization has bought anxiety to communities in the Horn of Africa. Focusing on Kenya, the paper examines and evaluates how governments’ security tactics have countered violent extremism. With the emphasis that countering violent extremism needs inclusive and strategic policies such as the philosophy of community policing, the paper addresses how community policing in Kenya adopts inclusive policies.

In analyzing the evolution of Kenyan foreign policy from the period of 1963 to 2020, I consider the contribution of psychology and sociology into security studies.  Comparing different cases such as the ‘Shifta wars,’ ‘Wagalla massacre,’ Anti-Terror legislation, International Criminal Court (ICC) cases, ‘Operation Linda Nchi’ (OLN), and Maritime Boundary Dispute (MBD) including their consequences.

The nature and extent of gender inequality and the conditions for farmer empowerment vary across countries, communities and regions. Although the status of women in agriculture has received extensive attention in the literature in recent decades, a research gap persists regarding the state of gender disparity in Farmers Field Schools (FFS) in Kilifi Sub-County.

Collective action through formation of commercial villages is one of the interventions adopted by Meru County government to enable smallholders farmers mitigate the market imperfections and contend with the recent transformations in agri-product markets. Despite this, most of the commercial villages are dysfunctional due to free riding and lack of member commitment regarding participation in the group and its operations. This study therefore, analyzed the determinants of decision to join commercial village, participation and intensity of participation in commercial village activities, in Buuri Sub-County, Meru County.

Microfinance institution contributes significantly to economic development and the financial inclusion of the underprivileged population. However, financial sustainability of these institutions remains a major challenge largely because of the low deposits and high demand for micro loans.  Though previous studies have shown that financial leverage influences financial sustainability of microfinance institutions, the findings are inconclusive and debatable. 

Kenya has for the last decade attempted to revitalize the structures for implementation of social protection programs through the formulation and implementation of the Kenyan Social Protection Policy, 2011. The policy was developed to provide a broader framework for design and execution of projects and programs that could address the needs of vulnerable groups such as, elderly persons, persons with disability and orphans and vulnerable children (OVCs).

The current global pandemic has not only changed the lives of people globally but also caused language change. Seemingly, there is a parallel language contagion to the pandemic given that some dictionaries have already made unscheduled updates in response to coronavirus-related vocabulary. Since previous research has reported pandemics and epidemics to have given rise to certain neologisms, the study aimed at exploring neologisms related to COVID-19 using data from digital platforms in Kenya.

DOWRY: A Possible Impediment to Happy Marriage

Payment of Dowry as a condition for legitimization of marriage is a common practice in many societies and is central to the ways in which the institution of marriage is understood and inserted in diverse African traditions.  In most African societies, it is taken for granted that the groom has a responsibility to pay, usually livestock, to the bridal family in return for her hand in marriage. 

Human African trypanosomiasis is a fatal vector-borne parasitic neglected tropical disease affecting millions of people in poorly developed regions of sub-Saharan Africa. It is caused by two subspecies of protozoan parasites: Trypanosoma brucei rhodesiense (Tbr) and T. b. gambiense.

The sustainability of eco concrete blocks industries is imperative to the well-being of our planet and to human development. However, the production of conventional cement, an essential constituent of eco concrete blocks leads to the release of a significant amount of carbon dioxide and other greenhouse gases. Conventional cement is not an environmentally friendly material due to the fact that its manufacture creates greenhouse gas emissions and leads to reduced supply of good-quality limestone and clay. The most energy-intensive stage of conventional cement production is during clinker production. It accounts for all but about 10% of the energy use and nearly all of the greenhouse gases produced by cement production.

Ecosystem services are biological foundations essential to economic prosperity and development of human beings for example water provision. However, when ecosystems are exploited for human sustenance, they affect water provision intensively. Kapingazi catchment provides various ecosystem services mainly water provision to downstream users including national hydroelectric power stations that contribute to 52.1% of hydro-electric power of Kenya's electricity.

Internationally, Lake Bogoria Production Landscape (LBPL) is important for wildlife species, biodiversity content and livestock feeds. However, it is at risk from degradation arising from unsustainable exploitation resources due to overstocking and inadequate natural pasture. Information on pasture species, places of planting and production capacity are well documented.

Infiltration rate is a fundamental parameter in understanding a wide range of soil functions. The determination of the infiltration rate in the field usually requires a lot of time. Horton's equation is a viable option when measuring ground infiltration rates or volumes since it provides a good fit to data. However it is cumbersome in practice since it contains three constants that must be evaluated experimentally.

Studies on invasive plant species have gained prominence owing to their potential to significantly alter plant species community composition and structure thereby negatively impacting on ecosystem services. The effects may include a reduction in the abundance of palatable plant species that constitute important forage for livestock, and medicines for the local communities.

Increase in population is driving increase in agricultural production and this is majorly experienced with smallholder farmers who are always engaging in diverse agricultural practices. This paper analyses smallholder dairy farmers farm utilization and relates this utilisation to constraints affecting smallholder dairy farmers capacity to improve manure management. Improved manure management would be useful for nutrient retention and minimizing GHG emissions. 

Semi-arid woodlands are important and critical habitats that provide breeding and feeding grounds for a variety of bird species, some of which are endangered or threatened with extinction. Habitat type and size influences abundance and diversity of birds globally and particularly in developing countries that are characterized by rapid human population growth and haphazard urban, agricultural and industrial development.

Nyiragongo volcano is the most active of the Virunga mountains located in the Western part of the Eastern Africa Rift system.  From the historical volcanic records, two recent eruptions January 10, 1977 and January 17, 2002 impacted heavily the environment where soil, forests, drainage system, settlement, farming and livestock were affected.

The impact of climate change on natural resources has necessitated the need to adapt potato farming to increase farmers’ resilience against climate change in Sub-Saharan Africa (SSA). Production of Potato (Solanum tuberosum. L) has been declining over the years in SSA due to climate change and variability. This has resulted to low food supply and low income among smallholder farmers exacerbating levels of food and nutrition insecurity, and poverty. For instance, in 2017, International Potato Center reported a tremendous reduction in potato yields by 56% due to reduced rainfall.  The study used data from 384 randomly selected potato farmers from Meru County through field survey.
