“…However, a feasibility study is necessary to establish the cost and compare it with the cost of other infrastructure such as sinking boreholes. Alternative rural water sources such as springs have been successfully harnessed and piped to communities using local energy sources other than electricity in Ethiopia [ 39 , 45 ]. Boreholes remain technologically challenging and costly to manage and maintain for the rural people.…”

“…Stakeholders could consider extending a small loan concept to WUGs for water and hygiene infrastructure maintenance similar to a successful NGO-BRAC model in Bangladesh [ 45 ]. This would provide access to appropriate sanitation and water infrastructure while earning interest for the WUGs and increasing their reserve funds for maintaining the water system.…”

Good sanitation and clean water are basic human rights yet they remain elusive to many rural communities in Sub-Saharan Africa (SSA). We carried out a cross sectional study to examine the impact of a four-year intervention aimed at improving access to water and sanitation and reducing waterborne disease, especially diarrhea in children under five years old. The study was carried out in April and May 2015 in Busangi, Chela and Ntobo wards of Kahama District of Tanzania. The interventions included education campaigns and improved water supply, and sanitation. The percentage of households (HHs) with access to water within 30 min increased from 19.2 to 48.9 and 17.6 to 27.3 in the wet and dry seasons, respectively. The percentage of HHs with hand washing facilities at the latrine increased from 0% to 13.2%. However, the incidence of diarrhea among children under five years increased over the intervention period, RR 2.91 95% CI 2.71–3.11, p < 0.0001. Availability of water alone may not influence the incidence of waterborne diseases. Factors such as water storage and usage, safe excreta disposal and other hygiene practices are critical for interventions negating the spread of water borne diseases. A model that articulates the extent to which these factors are helpful for such interventions should be explored.

“…Studies carried out in Bangladesh have highlighted the importance of renewable energy technology, viz. solar and biogas, for pumping water and for treating the water in rural areas without access to electricity which suffer from arsenic contaminated water [12,71]. The linkages of SDG6 with the targets associated with other SDGs 1, 2 and 7 are illustrated in Figure 7.…”

Abstract:Understanding the linkages between multiple targets of Sustainable Development Goals (SDGs) may help to integrate different sectoral programmes and develop coherent cross-sectoral policy to explore synergies. Synergy is interaction among two or more actions, which will lead to an impact greater or less than the sum of individual effects. Therefore, synergy can be positive or negative (trade-off). This paper aims at developing an analytical framework to evaluate sectoral linkages and examine potential synergies and trade-offs among various SDGs' goals and targets. Synergies and trade-offs related to energy access (SDG7), clean water and sanitation access (SDG6), food security and sustainable agriculture (SDG2) and poverty alleviation (SDG1) have been evaluated from the perspective of developing countries using examples from South Asia (Bangladesh, Nepal, and Sri Lanka) and Sub-Saharan Africa (Ghana, Ethiopia and Rwanda), and historical data for the period between 1990 and 2012. The analytical framework includes both qualitative and quantitative methods. Network analysis technique has been used for exploring the conceptual linkage among different indicators, and capturing the targets associated with SDGs. Advanced Sustainability Analysis (ASA) developed under the European framework programme has been used for quantifying the synergies and trade-offs among sustainability indicators. The analysis showed strong synergy among various SDG targets. Interestingly, the potential synergy differs from country to country and over time. Ghana and Sri Lanka had relatively higher potential synergy, whereas Rwanda and Nepal had relatively lower potential synergy among the various targets. Higher synergy values were evidenced in those cases where the policy have recognized and emphasized on linkages among cross-sectoral targets.

“…Some inroads have been made with anaerobic digesters, mainly for providing cooking fuel, and a few studies (i.e. [1][2][3]) have reported on the technoeconomic viability of biogas plants in such a setting. The country also has abundant solar resources; Palit et al [4] has studied the impact of enhancing energy access via solar pVbased decentralized power generation in Southeast Asia.…”

Despite the country's rural electrification program, kerosene is the predominant source for lighting, and woody biomass is virtually the only the option available for cooking. Aside from this energy service challenges the rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. Access to electricity, clean cooking gas, and safe drinking water services are genuine needs of the rural poor and are essential to improving welfare. These needs can be addressed individually or using an integrated approach. This study considers a holistic approach towards tackling both of these issues via integrated renewable energybased polygeneration employed at the community level. The polygeneration unit under consideration provides electricity via a pV array and cow dung-fed digester, which in turn is coupled to a gas engine. Excess digester gas is employed for cooking and lighting, while waste heat from the process drives a membrane distillation unit for water purification. The system is sized to serve a community of 52 households (Pani Para, Faridpur District) with 14 kWe peak demand and 250 kWh/day primary electricity loads. Technical assessments and optimization have been conducted with HOMER. Results show that electricity demand can be met with such a system while simultaneously providing 0.4 m 3 cooking fuel and 2-3 L pure drinking water per person per day. Cost estimates indicate that this approach is highly favorable to other renewable options.
