With the launch of the Swachh Bharat Mission (SBM), India accelerated access to improved sanitation in a 'mass movement' emphasising people's participation and political leadership. However, SBM continues to be implemented at the administrative unit of districts, disassociated from the political and electoral units of Parliamentary Constituencies (PC). We provide estimates of India's 543 PCs by their performance on three important Water Sanitation and Hygiene (WASH) indicators: unsafe disposal of child stool, unimproved drinking water supply, and unimproved sanitary facilities. We used multilevel modelling to generate precision-weighted estimates of each indicator at PC-level, based on recently developed methodologies linking cluster GPS data from the National Family Health Survey (NFHS), 2016 to potential PCs. We found very high heterogeneity across PCs ranging from 0.95 per cent–95.85 per cent for unsafe stool disposal, 0.35 per cent–64.17 per cent for unimproved drinking water source, and 0.19 per cent–90.69 per cent for unimproved sanitation facility. Unsafe child stool disposal and unimproved sanitary facility were strongly correlated ( r = 0.85, Pearson and r = 0.83, Spearman). Monitoring of SBM data at the PC level will allow parliamentarians to effectively improve WASH conditions in their constituencies, while accounting for critical between-PC variability that may be obfuscated in an approach focussed on state or district means.

Abstract
Background
Protracted, internal conflicts with geographic variations within countries, are an important understudied community exposure for adverse child health outcomes.
Methods
Violent events from the Uppsala Conflict Data Program (UCDP) between January 2016–December 2020 and January 2010–December 2015, were included as exposure events for children sampled in National Family Health Surveys (NFHS) 5 (2019–21) and NFHS 4 (2015–16), respectively. Geocoded data from UCDP were merged with residential clusters from NFHS, to identify children living in villages or urban blocks situated at <= 50 km from conflict sites. Within these clusters, which we defined as conflict exposed, we studied risks of stunting, underweight and wasting in children, prenatally, and in 0–3 years. We assessed sensitivity on a subsample of siblings with discordant conflict exposures.
Results
For NFHS 5, exposure to violence between 0 and 3 years was associated with 1.16 times (95% CI 1.11–1.20) higher risks of stunting, 1.08 (1.04, 1.12) times higher risks of underweight, and no change in wasting. In-utero violence exposure was associated with 1.11 times (95% CI 1.04–1.17) higher risks of stunting, 1.08 (95% CI 1.02–1.14) times higher risks of underweight, and no change in wasting, among children <= 2 years. In 17,760 siblings of 8333 mothers, exposure to violence during 0–3 years, was associated with a 1.19 times higher risk of stunting (95% CI − 0.24 to 0.084). Incremental quartiles of violence exposure had higher risks of stunting and underweight until quartile 3.
Conclusion
In-utero and early childhood indirect exposure to protracted conflicts were associated with increased stunting and underweight in India. Given the continued exposures of such historically and contextually rooted internal conflicts in many LMICs, chronic violence exposures should be targeted in public health policies as important social and political determinant of child health.
Decarbonisation of the economy has become a priority at the global level, and the resulting legislative pressure is pushing the chemical and energy industries away from fossil fuels. Microbial electrosynthesis (MES) has emerged as a promising technology to promote this transition, which will further benefit from the decreasing cost of renewable energy. However, several technological challenges need to be addressed before the MES technology can reach its maturity. The aim of this review is to critically discuss the bottlenecks hampering the industrial adoption of MES, considering the whole production process (from the CO2 source to the marketable products), and indicate future directions. A flexible stack design, with flat or tubular MES modules and direct CO2 supply, is required for site-specific decentralised applications. The experience gained for scaling-up electrochemical cells (e.g. electrolysers) can serve as a guideline for realising pilot MES stacks to be technologically and economically evaluated in industrially relevant conditions. Maximising CO2 abatement rate by targeting high-rate production of acetate can promote adoption of MES technology in the short term. However, the development of a replicable and robust strategy for production and in-line extraction of higher-value products (e.g. caproic acid and hexanol) at the cathode, and meaningful exploitation of the currently overlooked anodic reactions, can further boost MES cost-effectiveness. Furthermore, the use of energy storage and smart electronics can alleviate the fluctuations of renewable energy supply. Despite the unresolved challenges, the flexible MES technology can be applied to decarbonise flue gas from different sources, to upgrade industrial and wastewater treatment plants, and to produce a wide array of green and sustainable chemicals. The combination of these benefits can support the industrial adoption of MES over competing technologies ; This work was performed on the framework of the Science Foundation Ireland (SFI) Pathfinder ...
