Population dynamics, delta vulnerability and environmental change: comparison of the Mekong, Ganges–Brahmaputra and Amazon delta regions

Sustainability Science, Journal Year: 2016, Volume and Issue: 11(4), P. 539 - 554

Published: May 26, 2016

Tropical delta regions are at risk of multiple threats including relative sea level rise and human alterations, making them more vulnerable to extreme floods, storms, surges, salinity intrusion, other hazards which could also increase in magnitude frequency with a changing climate. Given the environmental vulnerability tropical deltas, understanding interlinkages between population dynamics change these is crucial for ensuring efficient policy planning progress toward social ecological sustainability. Here, we provide an overview trends Ganges-Brahmaputra, Mekong Amazon deltas. Using data sources, census Demographic Health Surveys, discussion regarding components undertaken context factors affecting demographic landscape three regions. We find that all cases broadly reflective national trends, although important differences exist within across study areas. Moreover, have been experiencing shifts structures resulting aging populations, latter being most rapid delta. The impacts on different important, extensive research required effectively quantify underlying relationships. paper concludes by discussing selected implications sustainable development beyond.

Incorporating institutions and collective action into a sociohydrological model of flood resilience

Water Resources Research, Journal Year: 2017, Volume and Issue: 53(2), P. 1336 - 1353

Published: Jan. 13, 2017

Abstract Stylized sociohydrological models have mainly used social memory aspects such as community awareness or sensitivity to connect hydrologic change and response. However, alone does not satisfactorily capture the details of how human behavior is translated into collective action for water resources governance. Nor it only mechanism by which two‐way feedbacks sociohydrology can be operationalized. This study contributes toward bridging this gap developing a model flood resilience that includes two additional components: (1) institutions action, (2) connections an external economic system. Motivated case community‐managed protection systems (polders) in coastal Bangladesh, we use understand critical general features affect long‐term human‐flood systems. Our findings suggest occasional adversity enhance resilience. Allowing some hydrological variability enter polder increase its adaptive capacity through preservation norm action. Further, there are potential trade‐offs associated with optimization resistance structural measures. By reducing floods, system may become more fragile under double impact floods change.

Food security outcomes in agricultural systems models: Current status and recommended improvements

Agricultural Systems, Journal Year: 2021, Volume and Issue: 188, P. 103028 - 103028

Improvement of food security is a common objective for many agricultural systems analyses, but how has been conceptualized and evaluated within not systematically evaluated. We reviewed the literature on analyses at household- regional-levels, finding that primary focus only one dimension security—agricultural output as proxy availability. Given comprises availability, access, utilization stability dimensions, improved practice would involve more effort to incorporate access indicators into models. The empirical evidence base including their determinants models requires further development through appropriate short long-term investments in data collection analysis. Assessment (through time) also particularly under-represented previous work application dynamic include indicators, coupled with formalized treatment robustness adaptability both regional household levels. find often conflate analysis covariates have potential improve (like yields) an assessment itself.

Migration as a human affair: Integrating individual stress thresholds into quantitative models of climate migration

Environmental Science & Policy, Journal Year: 2019, Volume and Issue: 93, P. 129 - 138

Published: Jan. 9, 2019

Sea level rise will expose millions of people to increasing coastal hazards and eventual land loss. Thus, it is important understand how residents make decisions about whether when move away with exposure. Historically, non-material dimensions human decision-making have been missing from quantitative modelling migration under environmental change. Here, we use behavioural theory the concept an inherent mobility potential define individual stress thresholds, represented in tension between residential satisfaction. We further suggest that as outcome determined by psychological propensity move, levels capital act modulate, rather than determine, responses, their timing outcome. Using southwest coast Bangladesh our case study, quantify these characteristics using results a 1500 household social survey exposure index based on projections sea surface height drawn physical model. Aggregating data village level, are able identify place-specific responses; for example, locations where high associated thus may occur earlier response hazard. By advancing thresholds demonstrating complex can be usefully quantified, ability such included approaches. The empirical contribute debates immobility climate change, most appropriate adaptive responses protect multi-dimensional well-being climate-vulnerable people.

Climate change, environmental stress and loss of livelihoods can push people towards illegal activities: a case study from coastal Bangladesh

Climate and Development, Journal Year: 2019, Volume and Issue: 11(10), P. 907 - 917

Published: March 5, 2019

This paper aims to understand how environmental stressors influence people's livelihood options in the coastal belt of Bangladesh. We argue that such as cyclones, riverbank erosion, salinity intrusion, and floods have negative impacts on lives by reducing their options. Twelve in-depth interviews (Livelihood Histories) twelve Focus Group Discussions (FGD) based two Participatory Rural Appraisal (PRA) tools (Village Timeline Contextual Change) were carried out three different sites Bangladesh conducted under study. Our study finds when there are insufficient adaptation strategies stressors, many people turn livelihoods banned government. These 'illegal livelihoods' include using fine mesh nets collect shrimp fry rivers well logging Sundarbans. often poorestand vulnerable, law enforcement only exacerbate vulnerability. end concluding those turned a result detrimental should be viewed special category vulnerable policymakers, steps need taken ensure resilience stressors.
