Background Numerous studies with varying associations between domestic use of solid biomass fuels (wood, dung, crop residue, charcoal) and respiratory diseases have been reported. Objective To present the current data systematically associating use of biomass fuels with respiratory outcomes in rural women and children. Methods Systematic searches were conducted in 13 electronic databases. Data were abstracted from original articles that satisfied selection criteria for meta-analyses. Publication bias and heterogeneity of samples were tested. Studies with common diagnoses were analysed using random-effect models. Results A total of 2717 studies were identified. Fifty-one studies were selected for data extraction and 25 studies were suitable for meta-analysis. The overall pooled ORs indicate significant associations with acute respiratory infection in children (OR 3.53, 95% CI 1.94 to 6.43), chronic bronchitis in women (OR 2.52, 95% CI 1.88 to 3.38) and chronic obstructive pulmonary disease in women (OR 2.40, 95% CI

BackgroundThe dimensions along which mortality is patterned in India remains unclear. We examined the specific contribution of social castes, household income, assets, and monthly per capita consumption to mortality differentials in India.Methods and FindingsCross-sectional data on 217 363 individuals from 41 554 households from the 2004–2005 India Human Development Survey was analyzed using multiple logistic regressions. Mortality differentials across social castes were attenuated after adjusting for household economic factors such as income and assets. Individuals living in the lowest income and assets quintiles had an increased risk of mortality with odds ratio (OR) of 1.66 (95% CI  = 1.23–2.24) in the bottom income quintile and OR of 2.94 (95% CI  = 1.66–5.22) in the bottom asset quintile. Counter-intuitively, individuals living in households with lowest monthly consumption per capita had significantly lower probability of death (OR  = 0.27, 95% CI  = 0.20–0.38).ConclusionsMortality burden in India is largely patterned on economic dimensions as opposed to caste dimensions, though caste may play an important role in predicting economic opportunities.

Abstract:In this paper, we present the Inter-Institutional Gap (IIG) framework as a novel approach to conceptualizing the often-overlooked interconnectivity of different rule-levels between formal and informal institutions in a natural resource system. This framework goes beyond the existing concepts of legal pluralism, institutional void, structural hole, and cultural mismatch, each of which offer valuable insights to particular gaps between formal and informal institutions, but do not sufficiently address the interaction at every rule level (i.e. constitutional choice, collective choice and operational choice rules). In order to demonstrate the potential of our framework for better understanding the underlying causes of inter-institutional gaps, we apply it to four case studies that encompass diverse geographical locations, governance levels, and social-ecological systems. Results reveal that institutional gaps tend to exist when there are unintended, unforeseen or hidden gaps between the different rule levels operating among the different institutions involved in governing a single resource system. More specifically we observe that: (i) inter-institutional gaps are co-existing, therefore if a certain gap is identified, other gaps may be expected; (ii) certain gaps may reveal latent gaps; and (iii) intermediaries may be key to addressing inter-institutional gaps. In many cases, sustainable natural resource management and regulation cannot be achieved without directly addressing the inter-institutional gaps that exist between formal and informal institutions operating in the same resource system. The framework facilitates analysis and understanding of multi-level governance structures in pursuit of addressing complex natural resource management issues.
