Coastal flooding will disproportionately impact people on river deltas

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Sept. 29, 2020

Abstract Climate change is intensifying tropical cyclones, accelerating sea-level rise, and increasing coastal flooding. River deltas are especially vulnerable to flooding because of their low elevations densely populated cities. Yet, we do not know how many people live on exposure Using a new global dataset, show that 339 million lived river in 2017 89% those the same latitudinal zone as most cyclone activity. We calculate 41% (31 million) population exposed deltas, with 92% (28 developing or least developed economies. Furthermore, 80% (25 sediment-starved which cannot naturally mitigate through sediment deposition.

Rice production and food security in Asian Mega deltas—A review on characteristics, vulnerabilities and agricultural adaptation options to cope with climate change

Journal of Agronomy and Crop Science, Journal Year: 2020, Volume and Issue: 206(4), P. 491 - 503

Published: July 14, 2020

Abstract Asian Mega deltas (AMDs) are among the world´s most important rice‐growing areas and vital for food security. This review describes major environmental agricultural characteristics as well current future threats to production livelihood, using three AMDs examples, namely Ganges–Brahmaputra delta in Bangladesh, Ayeyarwady Myanmar Mekong River Vietnam. In addition, we analysed widely used adaptation methods these areas. The threat agriculture is salinity intrusion water scarcity, which consequently leads a shortage of irrigation yield reduction. common applied strategies use salt‐tolerant varieties adjustment cropping calendars, water‐saving technologies. It was found that there many concepts address individual problems, but comprehensive integrated concept regions adapt climate change still missing.

Applying the global RCP–SSP–SPA scenario framework at sub-national scale: A multi-scale and participatory scenario approach

The Science of The Total Environment, Journal Year: 2018, Volume and Issue: 635, P. 659 - 672

Published: April 24, 2018

To better anticipate potential impacts of climate change, diverse information about the future is required, including climate, society and economy, adaptation mitigation. address this need, a global RCP (Representative Concentration Pathways), SSP (Shared Socio-economic SPA Policy Assumptions) (RCP-SSP-SPA) scenario framework has been developed by Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC-AR5). Application full at sub-national scales introduces two key challenges: added complexity in capturing multiple dimensions issues scale. Perhaps for reason, there are few such applications new framework. Here, we present an integrated multi-scale hybrid approach that combines both expert-based participatory methods. The applied within DECCMA1 project with purpose exploring migration three deltas across West Africa South Asia: (i) Volta delta (Ghana), (ii) Mahanadi (India), (iii) Ganges-Brahmaputra-Meghna (GBM) (Bangladesh/India). Using encompasses wide range (RCP8.5) combined SSP-based socio-economic scenarios (SSP2, SSP3, SSP5), generate highly divergent challenging contexts against which robustness human natural systems tested. In addition, consider four distinct policy trajectories: Minimum intervention, Economic capacity expansion, System efficiency enhancement, restructuring, describe alternative bundles actions/measures under different trajectories. paper highlights importance (combined top-down bottom-up) (joint expert-stakeholder) methods addressing uncertainty decision-making. facilitates improved assessments plausible choices (including migration) uncertain changing conditions. concept, methods, processes presented transferable to other socio-ecological settings challenges.

Sounding the Alarm: Health in the Anthropocene

International Journal of Environmental Research and Public Health, Journal Year: 2016, Volume and Issue: 13(7), P. 665 - 665

Published: June 30, 2016

There is growing scientific and public recognition that human actions, directly indirectly, have profoundly changed the Earth system, in a still accelerating process, increasingly called “Anthropocene”. Planetary transformation, including of atmosphere, climate, ecosystems biodiversity, has enormous implications for health, many which are deeply disturbing, especially low-income settings. A few health consequences Anthropocene been partially recognized, within environmental epidemiology, but their long-term remain poorly understood greatly under-rated. For example Syria could be “sentinel” population, giving glimpse to much wider dystopian future. Health-Earth research network, co-founded 2014, seeks, with other groups, catalyse powerful curative response by community. This paper builds on symposium presented members at 2015 conference International Society Environmental Epidemiology. It reviews synthesizes parts large literature relevant interaction between changing system health. concludes this topic should prominent future epidemiology Created our species, these challenges may soluble, solutions require far more understanding resources than currently being made available.
