Norms, attitudes and gender perspectives in ecological sanitation

In Kenya, the urban poor are residing in the Peri urban areas of Nakuru Municipality with inadequate sanitation facilities. This study investigated attitudes towards urine diverting toilets to popularize their use as viable alternative sanitation. Face to face interviews among 231 household respondents using a semi structured questionnaire, field observations, focused group discussions and key informant interviews were performed. Most of the respondents reported that the ecosan toilets are a viable option due to congested housing pattern, desire to own a toilet (for those who never had a toilet before), geohydrological conditions, improved privacy, and convenience among other factors. Most respondents preferred squatting type of urine diverting toilet, and are willing to reuse sanitized urine and feacal matter. Among the challenges noted include forgetfulness by some people to spray ash after defecating, misplaced water entering the toilet vault during cleaning and confusion in using the two holes. The provision for squat hole covers; modification of design, commitment and household change of behaviors are fundamental for encouraging more adoption and replication of the toilets. The study recommends more sanitation is dignity awareness campaigns through social marketing of Urine diverting toilets to salvage available water for improved livelihoods

Challenges of sustainable financing of sanitation in Nakuru Municipality, Kenya

Adequate sanitation is of great importance in addressing public health and plays an important role with respect to poverty alleviation. A large proportion of population in Nakuru is not served with adequate sanitation facilities. Worldwide experiences on financing of sanitation are widely scattered, and influenced by very different local circumstances. Little, if any, real linkage and upscaling has taken place, to draw conclusions that would fit all circumstances. A study was conducted in Nakuru municipality using structured questionnaires. Results from the data analysis indicated that majority of the households interviewed had low monthly incomes ranging between Kshs. 500010000. Sanitation therefore was not a priority with this meager income. The finding indicated that the only way these residents were willing to contribute to sanitation would be in kind labour, 44%. Majority of Nakuru residents, 65% admitted that they don’t pay for garbage collection services, reason being that of poverty and the notion that this is the responsibility of the municipal council. On household improvement priority, many respondents, 35% would prefer to have water in their residence followed closely with sanitation. They argue that with water availability, sanitation is guaranteed. Potential financial constraints were identified as unwillingness and inability to pay due to poverty, lack of political will and poor governance and low priority for sanitation in public sector spending due to competing interest with other sectors such as health and education

Sanitation challenges in learning institutions: the case of Nakuru municipality, Kenya

While every aspect of human development is vital, perhaps none is as important as the provision and access to improved sustainable sanitation. Whereas, the learning institutions are at the heart of transforming the nation and must sensitize and enrich the minds of the citizens, most schools’ sanitation facilities has been found wanting. Since the introduction of free primary education in Kenya in 2003, school enrolment has risen to about 7.3 million. In 2008, free secondary education was introduced raising significantly enrolments in secondary schools. These efforts may not realize their ultimate goalmeeting the MDGs. School’s sanitation and hygiene have received the least attention in the allocations of monetary resources. Against this background, this research sought to establish and report on the actual status of the schools’ sanitation facilities, hygiene standards and behaviour in the schools within the periurban areas of Nakuru Municipality. Findings would in turn inform existing NGOs such as ROSA which aims at promoting resourceoriented sanitation concepts being an innovative, affordable, adaptable and replicable approach to sustainable sanitation

Using Intermittent Sand Filters of Various Depths to Remove NH3-N, NO3N and NO2N from the Wastewater of Sugar Milling Factory

Intermittent sand filter systems have been used in wastewater treatment according to Selecky (2012) especially their application for on-site wastewater management. Intermittent sand filters have not been used to treat effluent from sugar factories in Kenya. There is very limited information on how to optimize their application in treating effluent from sugar factory in Kenya. This study focused on optimization of intermittent sand filter used in treatment of wastewater from sugar factory. Samples of wastewater were randomly taken from Kibos Sugar and Allied factories. These samples were loaded into sand filters with different sand depths of 0.30, 0.45 and 0.60m. Different loading rates, volumes and frequencies were applied for each depth. Samples from the filtrate were collected and analyzed in the laboratory for NH3-N, NO3-N and NO2-N values. The data was subjected to analysis of variance for fractional factorial (ANOVA) using the GenStat Version 13.2 computer programme. Wastewater generated from the sugar factories had NH3-N, NO3-N and NO2-N were within the WHO acceptable limits. The sugar factory managers targeting to remove NO3-N should use a sand filter with a depth of 0.45m by loading it at a rate of 2L/min, volume of 30L and frequency of 12hrs. To remove NO2N using a sand filter of 0.45 m deep, they should use a loading rate of 4L/min, loading volume of 10L and loading frequency of 12hrs. Keywords: Effluent, factory, filter, intermittent, sand, sugar, wastewater

The linkage between settlement profile and choice of sanitation system in peri-urban areas: a case study of Nakuru municipality

Presently human settlements in developing societies do not effectively address problems in urban areas including inadequate housing, unreliable energy sources, inadequate water supply, poor sanitation systems and lack of access roads in informal settlements. Recently, Nakuru town water supply has been characterized by chronic shortages and this threatens sanitation in residential and industrial functions within the Municipality. “Flying toilets” and pit latrines are conspicuous in low income high density settlements, while flush toilets, sewer systems and septic tanks are common among middle and high income low density settlements. A study was carried out to assess and map linkages between sanitation technologies and settlements profile in the municipality and examine implications of resource-oriented sanitation technologies. Results showed that sanitation situation in low income settlements and choice of sanitation technology is limited to multi-factors. 70% of respondents indicated a strain economically as a determining factor in the choice of sanitation technology. The research recommended the adoption of ecological sanitation as a paradigm shift from conventional sanitation

Characterization of greywater from urban and peri-urban areas of Nakuru Municipality, Kenya

Kenya faces serious challenges regarding water and sanitation services. Despite many years of government investment, existing facilities continue to deteriorate and have also failed to meet the demand of increasing population. These challenges are particularly severe in rapidly growing settlements of urban poor. One such settlement is Nakuru municipality which has an average annual population growth of about 8%. The municipality’s sewerage connection is inadequate (11% coverage) and only serves middle and high income areas. This study used a semi-structured questionnaire aiming at characterizing and determining the composition of greywater, besides identifying existing water supply and lifestyle characteristics

Recommendations for dealing with waste contaminated with Ebola virus: a Hazard Analysis of Critical Control Points approach

Objective To assess, within communities experiencing Ebola virus outbreaks, the risks associated with the disposal of human waste and to generate recommendations for mitigating such risks. Methods A team with expertise in the Hazard Analysis of Critical Control Points framework identified waste products from the care of individuals with Ebola virus disease and constructed, tested and confirmed flow diagrams showing the creation of such products. After listing potential hazards associated with each step in each flow diagram, the team conducted a hazard analysis, determined critical control points and made recommendations to mitigate the transmission risks at each control point. Findings The collection, transportation, cleaning and shared use of blood-soiled fomites and the shared use of latrines contaminated with blood or bloodied faeces appeared to be associated with particularly high levels of risk of Ebola virus transmission. More moderate levels of risk were associated with the collection and transportation of material contaminated with bodily fluids other than blood, shared use of latrines soiled with such fluids, the cleaning and shared use of fomites soiled with such fluids, and the contamination of the environment during the collection and transportation of blood-contaminated waste. Conclusion The risk of the waste-related transmission of Ebola virus could be reduced by the use of full personal protective equipment, appropriate hand hygiene and an appropriate disinfectant after careful cleaning. Use of the Hazard Analysis of Critical Control Points framework could facilitate rapid responses to outbreaks of emerging infectious disease

Theorising Global Governance Inside Out: A Response to Professor Ladeur

Professor Ladeur argues that administrative law’s postmodernism (and by extension Global Administrative Law) necessitates that we move beyond relying on ideas of delegation, account- ability and legitimacy. Global Governance, particularly Global Administrative Law and Global Constitutionalism, should try to adapt and experiment with the changing nature of the postmod- ern legality and support the creation of norms that will adapt to the complexities of globalisation. Ladeur’s contestation, similar to GAL’s propositions, can be challenged. By taking the International Criminal Tribunal for Rwanda, a significant contributor to the field of international criminal law, as an example, it is suggested that the creation of networks that Ladeur makes visible may not account for ‘regulatory capture’. This paper will argue that from the outside, the proliferation of networks may suggest that spontaneous accountability is possible. A closer look, however, drawing on anthropological insights from the ICTR, reveals that international institutions are suscepti- ble to capture by special interests. Furthermore, there are two central themes that animate the response to Professor Ladeur: the political nature of international institutions and the history of international law, and the role of institutions in this history

UNCERTAINTY ANALYSIS AND CALIBRATION OF SWAT MODEL FOR ESTIMATING IMPACTS OF CONSERVATION METHODS ON STREAMFLOW AND SEDIMENT YIELD IN THIKA RIVER CATCHMENT, KENYA

Despite their imperative role in water resources management, distributed hydrological models like SWAT require calibration that can be challenging due to uncertainties of parameters involved. Prior to modelling of hydrological processes, these parameters and their uncertainty range need to be identified. The objective of this study was to conduct uncertainty analysis of hydrological processes and to calibrate the Soil and Water Assessment Tool (SWAT) for stream flow and sediment yield modelling in Thika River catchment. Sequential Uncertainty Fitting program (SUFI-2) was used to conduct sensitivity and uncertainty analysis. Stream flow was calibrated and validated between the years 1998 to 2013 for gauging stations 4CB05 and 4CB04. Manual sediments calibration was achieved by constraining the MUSLE parameters using the bathymetric survey data. Two uncertainty indices, p and r factor, were obtained as 0.72 and 0.65, 0.65 and 0.45 during calibration and validation, respectively. Statisticalperformance indicators showed a good match between the observed and simulated values which indicated that the model was well calibrated for simulation of stream flow and sediments yield in the catchment
