Buriganga River

The Bangladesh government initiated the Buriganga River Restoration Project in 2010 to clean the heavily polluted Turag-Buriganga River. This study assessed the dynamic impact of the project on intergenerational well-being and developing a sustainable river system. The project outcomes were modeled for three future scenarios—varying waste control, streamflow, and migration control levels. System dynamics modeling—based on Streeter-Phelps’ water quality model and inclusive wealth (IW) index—was applied to secondary data (including remotely sensed data). The simulation model indicated that the project (with increasing streamflow up to 160 m3/s) will not ensure sustainability because dissolved oxygen (DO) is meaningfully decreasing, biological oxygen demand (BOD) is increasing, and IW is declining over time. However, sustainability can be achieved in scenario 3, an integrated strategy (streamflow: 160 m3/s, waste control: 87.78% and migration control: 6%) that will ensure DO of 8.3 mg/L, BOD of 3.1 mg/L, and IW of 57.5 billion USD in 2041, which is equivalent to 2.22% cumulative gross domestic product by 2041. This study is the first to use combined modeling to assess the dynamic impacts of a river restoration project. The findings can help policymakers to achieve sustainability and determine the optimal strategy for restoring polluted rivers.

The Way

In an era of mass mobility, those who are permitted to migrate and those who are criminalized, controlled, and prohibited from migrating are heavily patterned by race. By placing race at the centre of its analysis, this volume brings together fourteen essays that examine, question, and explain the growing intersection between criminal justice and migration control. Through the lens of race, we see how criminal justice and migration enmesh in order to exclude, stop, and excise racialized citizens and non-citizens from societies across the world within, beyond, and along borders. Neatly organized in four parts, the book begins with chapters that present a conceptual analysis of race, borders, and social control, moving to the institutions that make up and shape the criminal justice and migration complex. The remaining chapters are convened around the key sites where criminal justice and migration control intersect: policing, courts, and punishment. Together the volume presents a critical and timely analysis of how race shapes and complicates mobility and how racism is enabled and reanimated when criminal justice and migration control coalesce. Race and the meaning of race in relation to citizenship and belonging are excavated throughout the chapters presented in the book, thereby transforming the way we think about migration.

Study Results

Remote communities such as rural villages, post-disaster housing camps, and military forward operating bases are often located in remote and hostile areas with limited or no access to established infrastructure grids. Operating these communities with conventional assets requires constant resupply, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. For example, a 2000-member isolated village in northern Canada relying on diesel generators required 8.6 million USD of fuel per year and emitted 8500 tons of carbon dioxide. Remote community planners can mitigate these negative impacts by selecting sustainable technologies that minimize resource consumption and emissions. However, the alternatives often come at a higher procurement cost and mobilization requirement. To assist planners with this challenging task, this paper presents the development of a novel infrastructure sustainability assessment model capable of generating optimal tradeoffs between minimizing environmental impacts and minimizing life-cycle costs over the community’s anticipated lifespan. Model performance was evaluated using a case study of a hypothetical 500-person remote military base with 864 feasible infrastructure portfolios and 48 procedural portfolios. The case study results demonstrated the model’s novel capability to assist planners in identifying optimal combinations of infrastructure alternatives that minimize negative sustainability impacts, leading to remote communities that are more self-sufficient with reduced emissions and costs.

AbstractThis article explores the movement of children between households in Zambia as a site of ‘moral navigation’. Moral navigation extends Henrik Vigh's concept of social navigation from contexts of conflict and migration to more socially stable contexts in which well-being depends critically on people's ability to manage relationships. The live, dynamic and mobile character of these relationships means that they require active, real-time cultivation and response. While having practical objectives, these negotiations are also moral, articulated with ideas of what ought to be, and seeking to fulfil sometimes competing ethical projects. Life history interviews present three main perspectives: recollections of times in childhood spent away from birth parents; birth parents’ reflections on having a child living with others; and adults’ accounts of taking in other people's children. Strong norms of kinship unity and solidarity notwithstanding, in practice terms of engagement are differentiated through gender, marital, social and economic status, plus relational and geographical proximity. The pursuit of personal benefit contains the seeds of both contradiction and convergence with the collective good, as a relational understanding of moral selves sees one's own gain as proper, rightful and virtuous when it is realized in and through providing for others.

Purpose – The purpose of this paper is to provide an assessment of Malaysia's renewable capacity target. Malaysia relies heavily on fossil fuels for electricity generation. To diversify the fuel-mix, a technology-specific target has been set by the government in 2010. Considering the complexity in generation expansion, there is a dire need for an assessment model that can evaluate policy in a feedback fashion. The study also aims to expand policy evaluation literature in electricity domain by taking a dynamic systems approach. Design/methodology/approach – System dynamics modelling and simulation approach is used in this study. The model variables, selected from literature, are constituted into casual loop diagram. Later, a stock and flow diagram is developed by integrating planning, construction, operation, and decision making sub-models. The dynamic interactions between the sub-sectors are analysed based on the short-, medium- and long-term policy targets. Findings – Annual capacity constructions fail to achieve short-, medium- and long-term targets. However, the difference in operational capacity and medium- and long-term target are small. In terms of technology, solar photovoltaic (PV) attains the highest level of capacity followed by biomass. Research limitations/implications – While financial calculations are crucial for capacity expansion decisions, currently they are not being modelled; this study primarily focuses on system delays and exogenous components only. Practical implications – A useful model that offers regulators and investors insights on system characteristics and policy targets simultaneously. Originality/value – This paper provides a model for evaluating policy for renewable capacity expansion development in a dynamic context, for Malaysia.

Forest industry host communities are receiving increased attention from policy makers, academics, and municipal leaders. Recently, this attention is trained on measuring social and economic change at the community level and on identifying and developing avenues to greater community well-being. This paper examines aspects of two common social indicators, employment and migration, in the context of a forest-dependent community in Northern Alberta. By using statistical information along with two other major data sources that include interviews with local residents and a variety of reports from local institutions, specific social changes taking place within the community are described. Readers are cautioned against relying solely on statistical information to measure change and are encouraged to triangulate data with local sources. Such efforts may be more time consuming but the results are likely to provide more important insights into how and why certain communities are prospering while others are struggling. The paper concludes with a discussion of social capital as a crucial dimension of community well-being. Key words: forest-dependent communities, social indicators, employment, migration, mobility, community well-being, social capital
