The Impact

The study was conducted to evaluate the impact of Biosand Filter (BSF) on access to safe drinking water in the poor communities of the Philippine regions. Specifically, this endeavor aimed to describe the efficacy of the BSF as water system in the household and also as a bio-innovative technology for poverty alleviation. It also intended to reveal the effectiveness of household (HH) BSF in terms of the defined characteristics of the model as mechanism on access to safe drinking water. The study utilized the quasi-experimental design, which integrates quantitative and qualitative methods. Quantitative data were analyzed using econometric methods while the qualitative data used some statistical tools to control patterns, characteristics, and conditions of various study variables to eliminate alternative explanations of the observed outcomes. By contingent valuation method, the efficiency of BSF as a system to eliminate total coliform is high at 92.22%. Iron, Copper and Lead were 100.00% eliminated as well. More than 75.00% of Manganese, more than 54.90% of Zinc and more than 83.33% of Arsenic were filtered by the BSF. Clearness of effluent water improved by more than 58.19% and potential hydrogen (pH) improved by more than 13.22%. Cost-Benefit analysis revealed that BSF alleviates poverty 21.80 folds that of the cost of the filter. Around 79.26 percent of the rural poor HHs was satisfied with the functions of the model in their respective homes according to the over-all evaluation criteria for the effectiveness of BSF. The social dynamics of BSF to the HH is dependent upon three essential variables namely, the willingness of the HH to pay for the productivity cost of the filter, the social acceptance on the use of technology, and the social cultural adaptation of the HH on Biosand Filters.

Abstract Nonfunctionality of engineered water sources after two catastrophic cyclones—Sidr in November 2007 and Aila in May 2009—created acute scarcity of safe drinking water in coastal Bangladesh. The objective of this study was to estimate households’ willingness to pay (WTP) for disaster resilient water sources in Dacope upazila of Khulna District in southwestern coastal Bangladesh. By applying the double bounded dichotomous contingent valuation method to a dataset of 250 randomly selected households, we found that the mean WTP is BDT 263 and that inaccessibility to functional safe drinking water sources is the most significant determining factor of households’ WTP. Projecting mean WTP for a disaster resilient water source project in the study area, we measured a present value of aggregate WTP over project’s life span worth about BDT 624 (USD 7.37) million, which is about 14.30 times the present value of project’s aggregate establishment and maintenance cost. However, charging the local inhabitants a water tariff at mean WTP would lead to the exclusion of around 50% of the people from getting access to the improved water services or create a free riding problem. Through simulation exercises this study determined that the socially optimal water tariff is BDT 50 per month. This tariff would not only generate revenue of more than five times the project cost but would also create access to disaster resilient improved drinking water sources for almost 99% of the people.

The Way

The advent of technology has influenced the way banks should conduct their business. People are becoming more conscious, more discerning and more critical with the way how businesses should provide efficient, fast, and convenient access to their products and services. And banks are not exempted from these expectations. There has been a steady surge of innovative technology that will help banks deliver more efficient services through digitization. This study was conducted to investigate the determinants of the behavioral intentions on the acceptability of the bank’s digital mortgage service from the perspective of 250 mortgage clients who are current or prospective users of digital mortgage service. The study was anchored from the Unified Theory of Acceptance Use of Technology (UTAUT). The research has found that the determinants of behavioral intention to accept digital mortgage device among mortgage clients were facilitating conditions, performance expectancy and effort expectancy. It was also revealed that based on the standardized beta coefficients, facilitating conditions (0.405), performance expectancy (0.383) and effort expectancy (0.134) had a significant influence on bank mortgage clients’ behavioral intentions to accept digital mortgage service. Additionally, it was also proven that the age, education, computer knowledge and internet knowledge of the mortgage clients moderate the impact of the three determinants: performance expectancy, effort expectancy and social influence on clients’ digital mortgage service acceptance. Lastly, it can be concluded that performance expectancy is directly related to internet time, frequency of product purchase using a mobile device and use of mobile banking.

Contamination of shallow tube well drinking water by naturally occurring arsenic is a severe societal and human health challenge in Bangladesh. Multiple technological interventions seeking to ameliorate the problem face hurdles in securing social acceptance, i.e. the willingness of users to receive and use a technology. While most papers focus on expert understanding of social acceptability, this paper analyzes how users themselves understand the factors shaping the social acceptability of safe drinking water options in rural Bangladesh. We then deploy such understanding to comparatively assess which factors users see as most important in securing social acceptance for three safe drinking water options in rural Bangladesh: the arsenic removal household (Sono) filter; the deep tube well; and an improved dug well. We draw on focus groups and semi-structured interviews with technology users in six villages across three districts to analyze how users assess the social acceptability of specific arsenic-safe technologies. Our findings highlight that factors such as availability, affordability and compatibility with existing water use practices, as understood by users, are key to securing users' acceptance of a specific arsenic-safe option. In concluding, we point to a future research agenda to analyze user-oriented social acceptability of arsenic-safe technologies in developing country contexts.

The Impact

The purpose of this research is to examine how condom use is affected by specific aspects of the work environment: (1) social-structural and environmental influences and constraints, (2) mandatory condom use policy, and (3) the level of social influence and reinforcement between manager and employee. A total of 1,340 bar workers and 308 nonestablishment freelanceworkers comprise the study group. In establishments where a condom use policy exists, female barworkerswere 2.6 times more likely to consistently use condoms during sexual intercourse comparedwith establishments that do not have such a policy in place. The results suggest a need for the development of comprehensive educational policies in all entertainment establishments, including regular meetings with employees, reinforcing attendance at the Social Hygiene Clinic, promoting AIDS awareness, making condoms available in theworkplace, and mandating 100% condom use behavior among all employees.

The Impact

The impact of contaminants in water on minorities and economically disadvantaged persons was reviewed. Environmental legislation governing water was summarized as background information against which relevant studies were evaluated. The majority of the available information was anecdotal or case study and did not lend itself to making quantitative comparisons or analyses. However, the data did present certain trends that led to the conclusion that inequities concerning exposure to contaminants in water may exist. The following recommendations were made: current data bases should be analyzed and new data bases created to facilitate assessments of exposure to waterborne contaminants to all populations; an analysis of populations not covered by the Safe Drinking Water Act should be undertaken; a survey should be conducted of the drinking water infrastructure and the results evaluated to identify any impacts to minorities and economically disadvantaged persons; the social, cultural and economic characteristics that influence human exposure to waterborne contaminants need to be identified; and better educational and community outreach programs need to be developed and implemented.

Abstract This paper examines energy, drinking water and health nexus in India, and its consequences for the environment and economy. To establish this nexus, K-means cluster analysis and Davies–Bouldin validation index are employed to group 32 Indian states and union territories. The classification was performed based on 16 criteria, and the number of optimal clusters arrived at is 8. The nexus between energy, drinking water and health must be cautiously dealt with to ensure the social and economic growth of the nation. The criterion analysis of the states within these clusters indicates that states and union territories facing energy crises are usually deficient in safe drinking water services; consequently, people of those regions suffer from ill-health, which increases the economic burden on people through the loss of work productivity. With a deficient cash reserve, the communities are incapable of fulfilling the demand for energy and safe drinking water. However, while installing desalination plants to fulfil the need for safe drinking water, their environmental impact must be taken into account, as these systems have high energy consumption and significant environmental impact.
