Lack of sanitation and poor hygiene behavior cause a tremendous disease burden among the poor. This paper evaluates the impact of the Total Sanitation and Sanitation Marketing project in Indonesia, where about 11 percent of children have diarrhea in any two-week period and more than 33,000 children die each year from diarrhea. The evaluation utilizes a randomized controlled trial but is unusual in that the program was evaluated when implemented at scale across the province of rural East Java in a way that was designed to strengthen the enabling environment and so be sustainable. One hundred and sixty communities across eight rural districts participated, and approximately 2,100 households were interviewed before and after the intervention. The authors found that the project increased toilet construction by approximately 3 percentage points (a 31 percent increase in the rate of toilet construction). The changes were primarily among non-poor households that did not have access to sanitation at baseline. Open defecation among these households decreased by 6 percentage points (or 17 percent). Diarrhea prevalence was 30 percent lower in treatment communities than in control communities at endline (3.3 versus 4.6 percent). The analysis cannot rule out that the differences in drinking water and handwashing behavior drove the decline in diarrhea. Reductions in parasitic infestations and improvements in height and weight were found for the non-poor sample with no sanitation at baseline.

This book provides an analytical view of the successes and challenges encountered while creating the fast expanding rural sanitation movement in India, with a special focus on the last decade. While attempting to break the sanitation taboo in the country, this book presents a historical account of the importance attached to hygiene and sanitation in ancient India and the evolution of the sanitation policy. The key challenges and debates that have been encountered by policy makers while implementing the Total Sanitation Campaign have been discussed in detail along with a critical analysis of th

Bioenergy is renewable energy obtained from biomass—any organic material that has stored sunlight in the form of chemical energy. Biogas is among the biofuels that can be obtained from biomass resources, including biodegradable wastes like manure, sewage sludge, the organic fraction of municipal solid wastes, slaughterhouse waste, crop residues, and more recently lignocellulosic biomass and algae. Within the framework of the circular economy, biogas production from biodegradable waste is particularly interesting, as it helps to save resources while reducing environmental pollution. Besides, lignocellulosic biomass and algae do not compete for arable land with food crops (in contrast with energy crops). Hence, they constitute a novel source of biomass for bioenergy.Biogas plants may involve both high-tech and low-tech digesters, ranging from industrial-scale plants to small-scale farms and even households. They pose an alternative for decentralized bioenergy production in rural areas. Indeed, the biogas produced can be used in heaters, engines, combined heat and power units, and even cookstoves at the household level. Notwithstanding, digesters are considered to be a sustainable technology that can improve the living conditions of farmers by covering energy needs and boosting nutrient recycling. Thanks to their technical, socio-economic, and environmental benefits, rural biogas plants have been spreading around the world since the 1970s, with a large focus on farm-based systems and households. However, several challenges still need to be overcome in order to improve the technology and financial viability.
