In recent years, much focus has been put on the sustainability of water and sanitation development projects. Experts in this field have found that many of the projects of the past have failed to achieve sustainability because of a lack of demand for water and sanitation interventions at a grassroots level. For years projects looked to create this demand through various subsidy schemes, with the "software" of behavior change and education taking a backseat to the "hardware" of infrastructure provision. Community-Led Total Sanitation (CLTS) is a fairly new way of looking at the issues of increasing basic sanitation coverage, promoting good hygiene practices, and facilitating the change in behaviors that is necessary for a level of basic sanitation coverage to be sustained for any significant length of time. CLTS looks to get people to come to the realization that open defecation is dangerous, and that they have to power to stop this practice. The purpose of this research study was to assess the water, sanitation, and hygiene situation on the ground in villages that through CLTS have achieved open defecation free (ODF) status in the Mopti region of Mali, West Africa. This assessment was done through a willingness-to-pay study, that showed how important sanitation infrastructure was in the daily lives of villagers in this region of Mali. This research study also examines any possible correlations between certain socioeconomic data and willingness-to-pay. A questionnaire was developed and completed with 95 household heads spread across 6 of the 21 ODF villages in the region. The results of this research study show that the behavior change brought about by CLTS was sustained. Every household in the study had at least one latrine (total latrines = 186), or had access to a neighbor's latrine because theirs had recently collapsed. Of these latrines 82.3% were reported as meeting the Malian nation government requirements of basic sanitation. 89.3% of the observed latrines were built by the participant families themselves using predominately materials that could be found in or harvested from the local environment (e.g., mud, rocks, sticks). Fifty-three percent of the latrines were built completely free of cost, and of the 88 latrines that were paid for in part or in whole the average cost was about US $13.00. The majority of the participants (64.2%) in the research study reported making improvements and maintaining their latrines, clearly showing the importance of sanitation infrastructure in the 6 study villages. The average cost of this maintenance was about US $1.50. Alongside of willingness-to-pay data, more qualitative data were collected on the relative importance of sanitation infrastructure in the daily lives of people in ODF villages in Mopti. This study found that on average throughout the 6 study villages, about 13% of discretionary funds are saved for or spent on maintenance and improvements to sanitation infrastructure on a monthly basis. When sanitation infrastructure investments were compared with other infrastructure and livelihood investments, on the average it was ranked 7th out of the possible 10. These data seem to indicate that future investment in sanitation infrastructure was not a high priority for the participants. This could be stem from the fact that many of the participants had not directly experienced the need for continued investments, because their original latrines were still functional. The willingness-to-pay regression analysis produced very few statistically valid results. Only a few of the correlations found between willingness-to-pay data and socioeconomic characteristics of the sample were found to be statistically valid. For example, the correlation coefficient between willingness-to-pay for pit maintenance, including emptying when full or covering the pit with top soil, digging a new one, and reconstruction, and education level of the participants was about 1.2 and was statistically valid with a t-statistic of about 2.2. Indicating that the more educated a participant was, the more they would be willing to pay for pit maintenance. None of the overall regressions explained enough of the variability in willingness-to-pay data to be considered statistically valid. Regressions for two scenarios, constructing a cement slab as an improvement to an existing latrine and sealing/lining the pit on an existing latrine with cement, explained 10.3% and 10.4% of the variability in willingness-to-pay data respectively. However, this did not meet the minimum criteria of 15%. While the willingness-to-pay data would have been useful to study partners that are piloting a Sanitation Marketing program in Mali, the main research objective of assessing the CLTS intervention was still met.

Access to safe water and improved sanitation remains threatened by the ever increasing demand in urbanised cities of the world. Adequate management of this problem could not be achieved through technical and regulatory methods alone. A human values-based education approach, namely the Human Values Water, Sanitation and Hygiene Education (HVWSHE) programme, was considered a suitable intervention strategy to bring about the desired changes in attitude and behaviour by the water users. This research involves an empirical case study approach that explores the experiences of Laotian teachers as adult learners of the HVWSHE intervention as well as a literature study on adult education, adult learning facilitation, human values-based education and teacher beliefs. Focus group meetings, lesson observations, participant observation, field notes and a researcher journal was used to collect data. This study revealed that the HVWSHE training programme had a positive effect on the adult learners’ attitude and behaviour towards a better water-use and sanitation-friendly ethic. / Educational Studies / M.

<p>The Lake Bosomtwe impact crater is located in the Ashanti region of Ghana, West Africa. The impact crater diameter from rim to rim is approximately 10.5 km wide with a lake located at the center. Three different districts touch the lake containing 155,000 hectacres of land. There are approximately 7,500 people from 24 villages, and 12 of those villages reside within walking distance of the lake shore. Within the last ten years, the lake has been subjected to overfishing and environmental degradation. The health of the lake has declined due to overfishing and algae blooms caused by improper fertilization rates. Because of these factors, residents of the area have been forced to transition to subsidence farming as their main vocation. According to the Ghana Statistical Service group, 97.6% of the population participates in some form of rural crop farming (Ghana Statistical Service, 2010). Experience with common practices such as crop rotation, fertilizer use, and erosion control is extremely limited. The lake has not been recommended for recreational use due to the excess runoff in the form of agrochemicals, liquid, and organic waste. Caged aquaculture and traditional fishing within Lake Bosomtwe is currently illegal.</p><p><br></p><p>A comprehensive Institutional Review Board (IRB) survey was developed for the six primary research questions to be examined. From these six research questions, 147 specific questions were developed. Three of the 147 questions were to obtain Global Positioning System (GPS) data for community households, pit latrines, and water wells or boreholes. This study sought to interview 10-15 farmers per village, for each of the 12 villages located along the shore of Lake Bosomtwe of their perspective on land use change/cover in the Lake Bosomtwe area, current farming practices, current water sanitation and hygiene practices, and current fishing practices. These surveys were collected in the form of oral responses, for which 118 small-holder farmers were interviewed. Of the participants surveyed, 66% were qualified to answer all questions, and 100% of participants completed the survey.</p><p><br></p><p>Some specific statistical tests were conducted based of market assessment survey. It was determined that no association between gender and level of education existed. Meaning, that female participants interviewed have just as many opportunities as male participants to pursue education beyond Junior High School (JHS). Yield averages between the villages on the north side of the lake with road access and villages on the southern portion of the lake with limited to no road access were determined to be significantly different. It was determined that road access does affect village yield. When comparing average usable yields between villages located on the northern side of the lake with road access or between villages on the southern side of the lake with limited to no road access, these results were not statistically significant. No significant difference in the scores for villages with road access on the northern side of the lake and villages with limited to no road access on the southern side of the lake existed. Therefore, road access does not affect village usable yield. Through statistical analysis an association was determined between people who practice bathing and washing in the lake and those who practice fishing as a form of livelihood.</p><p><br></p><p>Four decision matrices were created to prioritize the following items: Farm Components, technologies to showcase at an appropriate technology center, improved farming practices to showcase through Demonstration Plots, and extension outreach topics. The top three results for the Farm Components were: Appropriate Technology Center (ATC), Demonstration Plots, and a Micro-Credit Union. The top three technologies to showcase as part of the ATC are: PICS Bags, Moisture Meters, and Above-Ground Aquaculture. The three demonstration plots recommended terracing/erosion control, crop rotation, and cover crops. The highest priority extension outreach topics were: basic home/farm finance, improving health through washing stations, and post-harvest loss prevention. The top three priorities of each decision matrix will be the focus of further study, so that these topics can be developed and programs focusing on these needs can be implemented in collaboration with the community partners.</p>

<p>In developing countries water access is not always available. In many locations around the world, people lack sufficient access of water for both drinking and domestic purposes and use unsafe water sources. Particularly in sub-Saharan Africa, women and children walk great distances to obtain access to water. People must have equitable and affordable access to safe and sufficient water that is palatable and in sufficient quantity for both drinking and domestic purposes before any other long-term economic development or social improvement can occur. This research seeks to increase access to subsurface water by improving the driving capabilities of the Well-Driver PUP (Purdue Utility Project) vehicle. The Well-Driver PUP is a low-volume manufactured utility vehicle with a hydraulic post driver mated to it in order to mechanize tube well installation. </p> <p>Worldwide, there are many locations where the water table depth is less than 23 meters, specifically in the 10-20 meters range. These areas include sub-Saharan Africa, the Caribbean, South America, northern India, Asia, and parts of the Asia Pacific Islands. These locations are places where the Well-Driver PUP could potentially be utilized, if sufficient reliability and depth can be demonstrated on a repeatable basis. This would increase the number of locations throughout the world that the vehicle could be used to access ground water for those with limited to no current water access. Ghana is one of the many countries located within sub-Saharan Africa where the Well-Driver PUP could have a positive impact.</p> <p>The author has had significant professional experience working in Ghana on various international development projects related to agriculture, water, sanitation, and hygiene (WASH). She has been part of international development projects in Ghana, Tanzania, and Haiti, with experience working cross-culturally since 2014. She has worked on projects specifically in Ghana for more than 9 years and has been part of more than 32 different water resource projects within the country. Therefore, consideration is specifically given to the appropriateness of the Well-Driver PUP as first piloted in Ghana. For this work, a cost analysis of using the Well-Driver PUP per depth and comparison to current driven wells in Ghana was carried-out. </p> <p>A review of the literature was conducted. Four research questions and experiments were established. Experiment 1 carried-out three different pipe stack numerical loading studies that were simulated in Fusion 360® (Autodesk, San Rafael, CA). Load models were examined of a centered hit, a non-centered hit, and a well point only. It was shown that the average dynamic impact force applied by the driving ram was calculated to be 39 kN. FEA analysis was conducted in Fusion 360®, and it included Von Mises, safety factor, and displacement results. The average dynamic impact force that the Well-Driver PUP applies was less than both the yield stress and ultimate tensile strength of ASTM A53 steel, indicating that no deformation or breakage of the well point should be expected. </p> <p>Experiment 2 included increasing the weight of the driving ram, through the addition of weight plates. A series of wooden fence post installations using these new weight additions was conducted. This experiment allowed for a regression model to be developed predicting the impact of weight added to the driving ram, the drop height of the ram, and the soil moisture content, on the driving depth of the vehicle. The MLR model included the penetration depth (Y), weight added (X₁), drop height (X₂), and soil moisture content (X₃). The model coefficient estimates were determined, and the predictor variables were all found to be significant at p < 0.01.</p> <p>Experiment 3 focused on improved reliability and finding the maximum depth capabilities of the Well-Driver PUP with new weight additions added to the driving ram. Two attempts were made to determine the driving depth capabilities of the vehicle. Both well installations were conducted in Montgomery County Indiana. Water was struck at both locations. At the first location, final well depth was 2.1 m with a 0.76 m of water within the column. The driver encountered a layer of blue-gray clay that it was unable to pass through. </p> <p>A second driving attempt was made to install a deeper well. The final well depth was 5.0 m with 1.67 m of water within the column. At this location, it is believed that a layer of limestone, shale, or siltstone was encountered. Comparing the compressive strength of limestone, sandstone, and shale, the Well-Driver PUP was not capable of driving through such materials. Therefore, at both well locations, the maximum driving depth capabilities of the driver were achieved. At both installation locations, the wells were formally developed. Both sets of water quality samples were submitted to the Montgomery County Health Department and received satisfactory ratings. </p> <p>Experiment 4 resulted in the fabrication and design of a 4” well point. The fabricated well point was installed to create a completed well at a depth of 2.7 m in Linden IN. There was 0.1 m of water within the pipe column. The well was formally developed, and the water quality results received a satisfactory rating. A cost analysis of a 4” well by depth was conducted. The total cost to fabricate one well point totaled $661.42. Of the total cost, 81% of the costs came from the 4” base pipe and the specialty pre-perforated screen used to create the secondary screen. The completion of these experiments provides a better understanding of the driving capabilities of the Well-Driver Pup. Improving the driving depth capabilities of the Well-Driver Pup will help to push this low-cost alternative technology closer to release in the developing world.</p> <p><br></p>
