Abstract Background Estimates indicate that household air pollution caused by solid fuel burning accounted for about 1.03 million premature mortalities in China in 2016. In the country’s rural areas, more than half the population still relies on biomass fuels and coals for cooking and heating. Understanding the health impact of indoor air pollution and socioeconomic indicators is essential for the country to improve its developmental targets. We aimed to describe demographic and socioeconomic characteristics associated with solid fuel users in a rural area in China. We also estimated the risk of cardiovascular disease and all-cause mortality in association with solid fuel use and described the relationship between solid fuel use, socioeconomic status and mortality. We also measured the risk of long-term use, and the effect of ameliorative action, on mortality caused by cardiovascular disease and other causes. Methods We used the China Kadoorie Biobank (CKB) site in Pengzhou, Sichuan, China. We followed a cohort of 55 687 people over 2004–13. We calculated the mean and standard deviation among subgroups classified by fuel use types: gas, coal, wood and electricity (central heating additionally for heating). We tested the mediation effect using the stepwise method and Sobel test. We used Cox proportional models to estimate the risk of incidences of cardiovascular disease and mortality with survival days as the time scale, adjusted for age, gender, socioeconomic status, physical measurements, lifestyle, stove ventilation and fuel type used for other purposes. The survival days were defined as the follow-up days from the baseline survey till the date of death or 31 December 2013 if right-censored. We also calculated the absolute mortality rate difference (ARD) between the exposure group and the reference group. Results The study population had an average age of 51.0, and 61.9% of the individuals were female; 64.8% participants (n = 35 543) cooked regularly and 25.4% participants (n = 13 921) needed winter heating. With clean fuel users as the reference group, participant households that used solid fuel for cooking or heating both had a higher risk of all-cause mortality: hazard ratio (HR) for: cooking, 1.11 [95% confidence interval (CI) 1.02, 1.26]; heating, 1.34 (95% CI 1.16, 1.54). Solid fuel used for winter heating was associated with a higher risk of mortality caused by cerebrovascular disease: HR 1.64 (95% CI 1.12, 2.40); stroke: HR 1.70 (95% CI 1.13, 2.56); and cardiovascular disease: HR 1.49 (95% CI 1.10, 2.02). Low income and poor education level had a significant correlation with solid fuel used for cooking: odds ratio (OR) for income: 2.27 (95% CI 2.14, 2.41); education: 2.34 (95% CI 2.18, 2.53); and for heating: income: 2.69 (95% CI 2.46, 2.97); education: 2.05 (95% CI 1.88, 2.26), which may be potential mediators bridging the effects of socioeconomic status factors on cardiovascular disease and all-cause mortality. Solid fuel used for cooking and heating accounted for 42.4% and 81.1% of the effect of poor education and 55.2% and 76.0% of the effect of low income on all-cause mortality, respectively. The risk of all-cause mortality could be ameliorated by stopping regularly cooking and heating using solid fuel or switching from solid fuel to clean fuels: HR for cooking: 0.90 (95% CI 0.84, 0.96); heating: 0.76 (95% CI 0.64, 0.92). Conclusions Our study reinforces the evidence of an association between solid fuel use and risk of cardiovascular disease and all-cause mortality. We also assessed the effect of socioeconomic status as the potential mediator on mortality. As solid fuel use was a major contributor in the effect of socioeconomic status on cardiovascular disease and all-cause mortality, policies to improve access to clean fuels could reduce morbidity and mortality related to poor education and low income.

Amidst climatic and economic volatility, agricultural development and climate adaptation policies have increasingly turned to weather microinsurance to manage uncertainties, particularly in dryland pastoral and agricultural settings. While the political embrace of insurance has been cause for concern amongst those who fear insurance will undermine embedded coping mechanisms and moral economies, economists have puzzled over low insurance adoption rates amongst target populations. This article argues for an approach that scrutinizes insurance in relation to dynamic social practices and norms for responding to uncertainty. We employ this approach to investigate pastoralists’ encounters with index-based livestock insurance in Northern Kenya and Southern Ethiopia. Drawing on interview, ethnographic, and survey data, we demonstrate how insurance is understood within larger moral economies and collective imaginaries for living with and managing uncertainty in the drylands. Relational understandings shape pastoralists’ participation in risk-sharing arrangements, collective and individual decisions about livestock insurance purchase, and eventual uses of insurance payouts. Payouts also support a broad array of social reproductive purposes and investments in social and political life. As we conclude, these findings upset the binary between formal and informal insurance, revealing how “formal” index insurance must be negotiated with embedded social affiliations, rights, obligations, and understandings of uncertainty.

Residential buildings consume a vast amount of energy throughout their whole-life cycles with the subsequent greenhouse gases (GHG) emitted in the atmosphere. This phenomenon will only be exacerbated by projected trends in excessive urbanisation and global population. It is therefore imperative to investigate and quantiatively evaluate the environmental impacts of housing in different regions and contexts in order to enable better and more informed decisions.This is even more urgent in cases where the possibility for urban development is limited or severely constrained. Palestine represents one such areas of the world, and this research focuses on a comparative life cycle assessment (LCA) of contemporary and traditional housing typologies in the region. Primary data has been collected to provide a reliable basis for the LCA, which has been carried out according to the existing international standards. In addition to energy demand and GHG emissions, additional environmental impact categories have been further evaluated to provide a more holistic sustainability analysis.Results—strengthened by an uncertainty analysis—show that environmental impacts, energy use, and global warming potential for contemporary houses are for the most much higher than those for traditional houses. This is mainly due to the high impact of concrete and steel, but further exacerbated by the low impact of limestone as a suitable building material for the region. The results presented in this article signpost an important starting point in investigating the real mitigation potential of specific materials (e.g. limestone and lime mortar) when employed at scale in specific regions of the world. Our findings can also contribute to developmental policies for the region, with an aim of reducing the anthropogenic pressure on the natural environment.

The access to modern energy services are deeply embedded in most aspects of the economic, social, and environmental dimensions of human development. In Mozambique, just a small fraction of the rural population has access to electricity, as the electrification process so far has relied on a leastcost approach, only inciting the development and extension of the national grid. As the population of rural off-grid communities are often highly dispersed, having low purchasing power, low technical skill etc., keeping current unilateral electrification approach, will mean that the many isolated communities will be left in the dark in the many years to come. This therefore calls forward the need to apprehend other approaches to make electricity accessible in the rural off-grid areas of Mozambique. In present thesis the opportunities and constraints of providing electricity to rural offgrid areas are assessed. Meeting the potential of the rural off-grid challenge, which Mozambique currently faces, takes outset in the establishment of community-based electrification pilot projects.

AbstractClimate change impacts are being felt across sectors in all regions of the world, and adaptation projects are being implemented to reduce climate risks and existing vulnerabilities. Climate adaptation actions also have significant synergies and tradeoffs with the Sustainable Development Goals (SDGs), including SDG 5 on gender equality. Questions are increasingly being raised about the gendered and climate justice implications of different adaptation options. This paper investigates if reported climate change adaptation actions are contributing to advancing the goal of gender equality (SDG 5) or not. It focuses on linkages between individual targets of SDG 5 and climate change adaptation actions for nine major sectors where transformative climate actions are envisaged. The assessment is based on evidence of adaptation actions documented in 319 relevant research publications published during 2014–2020. Positive links to nine targets under SDG 5 are found in adaptation actions that are consciously designed to advance gender equality. However, in four sectors—ocean and coastal ecosystems; mountain ecosystems; poverty, livelihood, sustainable development; and industrial system transitions, we find more negative links than positive links. For adaptation actions to have positive impacts on gender equality, gender-focused targets must be intentionally brought in at the prioritisation, designing, planning, and implementation stages. An SDG 5+ approach, which takes into consideration intersectionality and gender aspects beyond women alone, can help adaptation actions move towards meeting gender equality and other climate justice goals. This reflexive approach is especially critical now, as we approach the mid-point in the timeline for achieving the SDGs.

The goal of providing universal energy access to all by 2030 under the UN‐led SE4ALL initiative calls for new and innovative solutions to rural electrification and is fuelling the recent interest in mini‐grids. Mini‐grid solutions are emerging as a third alternative to rural electrification, coming between the option of large‐scale grid extension and pico‐scale stand‐alone solutions like solar home systems or solar lanterns. International expectations of mini‐grids are high, with the International Energy Agency suggesting that they will play a significant role in reaching the goal of universal access. Based on a detailed review of past, ongoing, and planned mini‐grids in East Africa, this study seeks to deconstructs the popular notion of mini‐grids for rural electrification in East Africa. The study reveals that so far activities carried out under the heading of mini‐grids to a large extent consist of the hybridization of existing utility‐owned electricity systems for medium‐size towns located far from the grid, which does not necessarily contribute to rural electrification. However, limited but increasing activity is identified regarding the use of mini‐grids to bring electricity to rural villages and smaller rural towns. This is of specific interest because it is for this type of mini‐grid that the main challenges are to be found with respect to identifying and testing adequate financing, ownership, and business models. Based on the trajectories identified for mini‐grids for rural electrification and the challenges identified in the literature, the study concludes by proposing three avenues for further research.

As conflicts between emissions reductions and economic growth intensify, an increasing number of countries and regions are focusing on green total factor productivity (GTFP). Financial agglomeration (QWS), resource endowment (SE), and innovation-driven (ID) are the main factors that cause regional differences in GTFP. However, few scholars have comprehensively considered the impact of the interaction between SE, ID, and QWS on GTFP. This article uses the Global Malmquist-Luenberger (GML) index to calculate the GTFP of 30 Chinese provinces from 2003 to 2020 and constructs a dynamic panel model to present the first comprehensive study of the interactions between SE, ID, and QWS and their relationship with GTFP. The conclusions are as follows. (1) SE is positively correlated with GTFP, which is different from the “resource curse” theory proposed by existing research. (2) There is a crowding-out effect between SE and ID, and their interaction will restrain the growth of GTFP. (3) QWS promotes ID, and the interaction between the two promotes the growth of GTFP. (4) There is a restraining effect between QWS and SE, and their interaction will hinder the growth of GTFP. (5) The key policy directions to improve China's GTFP are to undertake strategic planning from a comprehensive perspective, including encouraging innovation, guiding financial development reasonably, and avoiding excessive consumption of resources.

All countries in Europe have road fuel taxes and these account for roughly half of the net fuel price. We compare current road fuel taxes and corrective taxes, estimated on the basis of negative externalities from road transport for 22 European countries, taking into account the effect of fuel taxation on fuel efficiency. We focus on cars running on diesel or petrol and commercial vehicles running on diesel. If fuel taxes were intended to internalize all road transport externalities, then a number of countries could be considered to be on the right path already in what respects petrol taxation. Diesel, on the other hand, seems to be under-taxed in all 22 countries. Petrol tax increases would be in order in some countries and diesel tax increases would be in order in all 22 countries, at least as a bridge until fine-tuned policies, such as widespread peak congestion pricing or pay-as-you-drive insurance can be put in place.
