Adaptation to climate change as resilience for urban extreme poor: lessons learned from targeted asset transfers programmes in Dhaka city of Bangladesh

This paper aims to identify how targeted asset transfers help to build adaptive capacity and adaptive actions of the urban extreme poor to climate change phenomena. This paper explores the theoretical debates of community-based adaptation approach and failure of such approach to address urban extreme poor. The empirical evidence of these theoretical debates will be drawn from two informal settlements of Dhaka city, where a targeted asset transfer project has been implementing since 2009. This paper explains that urban extreme poor usually work as unskilled labour and lack different livelihood capitals; and climate change is an increasingly important influence exacerbating an already vulnerable livelihood context. There is growing recognition in the literature that poor urban people and communities are adapting to climate change in physical and behavioural terms. But, in the case of urban extreme poor these adaptation approaches are delivering short-term survival strategies disregarding the notion of wellbeing in the medium to long-term perspectives. It is also evident that community level initiatives structurally reproduce the exclusion of the urban extreme poor. However, poverty literatures acknowledge that poverty-centred approaches could help to reduce vulnerability. As urban extreme poor are significantly more resource constrained, it is reasonable to assert that targeted asset transfers could be a poverty-centred adaptation approach in a changing climate. Targeted asset transfers approaches are the outcomes of recent social protection revolution that especially consider accumulation of physical, financial, human, and social capital in order to build adaptive capacity of the urban extreme poor. This adaptive capacity of the extreme poor may facilitate adjustments in assets, livelihoods, behaviours, and technologies in order to reduce future climate vulnerability. In this context, this paper seeks to answer whether targeted asset transfer approaches can be considered as effective poverty-centred adaptation approaches for the urban extreme poor or not.

Consumers’ intention-based influence factors of renewable energy adoption in Pakistan: a structural equation modeling approach

As the adoption of renewable energy (RE) is a complex and intricate procedure affected by a wide range of factors, it prompts traction among researchers to examine these influence factors. The aim of this study is to scrutinize the factors affecting consumers’ intention to adopt RE for household use in Pakistan. The current research has contributed through expanding the structural framework of the theory of planned behavior by incorporating three novel factors (perception of self-effectiveness, perception of neighbor’s participation, and belief about RE benefits) to have a deep insight into the factors that motivate or inhibit consumers to adopt RE. Outcomes are based on the primary data compiled from 353 households in the five main cities of Pakistan accompanying an inclusive survey. The state-of-the-art structural equation modeling was utilized to test and analyze the proposed hypotheses. The results signify that the influencing factors such as perception of self-effectiveness, awareness of RE, and perception of neighbor’s participation impart a positive effect on consumers’ intention to adopt RE, whereas cost of RE generation has an opposite effect. Interestingly, environmental concern and belief about RE benefits found to have neutral effects. Research results emphasize the need to enhance public awareness, reform policy structure, transform social norms, and highlight the benefits that RE provides, all through an integrative and coherent way.

Experimental and Monte Carlo simulation studies of open cylindrical radon monitoring device using CR-39 detector

There are several methods of measuring radon concentrations but nuclear track detector cylindrical dosimeters are widely employed. In this investigation, the consequence of effective volumes of the dosimeters on the registration of alpha tracks in a CR-39 detector was studied. In a series of experiments an optimum radius for a CR-39-based open cylindrical radon dosimeter was found to be about 3 cm. Monte Carlo simulation techniques have been employed to verify the experimental results. In this context, a computer code Monte Carlo simulation dosimetry (MOCSID) was developed. Monte Carlo simulation experiments gave the optimum radius of the dosimeters as 3.0 cm. The experimental results are in good agreement with those obtained by Monte Carlo design calculations. In addition to this, plate-out effects of radon progeny were also studied. It was observed that the contribution of radon progeny (218Po and 214Po) plated-out on the wall of the dosimeters increases with an increase of dosimeter radii and then decrease to 0 at a radius of about 3 cm if a point detector has been installed at the center of the dosimeter base. In the code MOCSID different types of random number generators were employed. The results of this research are very useful for designing an optimum size of radon dosimeters.     

Fly ash leachate induces oxidative stress in freshwater fish Channa punctata (Bloch)

Oxidative stress inducing potential of fly ash leachate (FAL) was studied in a freshwater fish, Channa punctata (Bloch). Fish were exposed to fly ash leachate for 24 h and lipid peroxidation (LPO) was studied as a marker of oxidative stress. Catalase (CAT), glutathione S-transferase (GST) activities and levels of reduced glutathione (GSH) were also estimated in the exposed fish. FAL (1 ml/l) induced LPO in all the organs and most prominent response was in the gill. It also caused induction of enzymes and glutathione. Liver showed highest level of induction of enzyme activities. The results of this study demonstrate that fly ash constituents have potential to induce oxidative stress in fish and gills are the most vulnerable organs. It is also suggested that in case of exposure to FAL, along with LPO antioxidant defense is also activated to counteract the reactive oxygen species (ROS) at least partly in the initial stages of exposure.
