Sea-level rise poses a significant threat to Small Island Developing States (SIDS) due to the concentration of people, assets, and infrastructure in coastal zones. This review assesses literature on key emerging topics in sea level rise including: the lasting impact of near-term mitigation on long-term sea-level rise; new global coastal vertical elevation data and their impact on existing sea-level rise projections; and the interaction of sea-level rise with other hazards, including salinization, tropical cyclones and extreme precipitation.
Loss and Damage studies have tended to focus on rapid-onset events with lesser attention to slow-onset events such as drought. Even when discussed, narratives around droughts emphasize implications on rural populations and there remain empirical and conceptual gaps on drought impacts in urban areas. We focus on losses and damages associated with urban drought and water insecurity through a review of interventions and policies in seven Asian countries. We find evidence of urban droughts leading to tangible losses (e.g. groundwater over-extraction, economic impacts) and intangible losses (e.g.
Sea level rise and land subsidence — induced flooding are projected to have severe impacts on highly populated Asian deltaic cities. These cities are already suffering from frequent floods, though few comparative analyses have been conducted on the similarities and differences of their adaptation approaches. Thus, this study aims to investigate the current adaptation pathways of Asian deltaic cities to flooding induced by slow onset events such as urbanization-induced land subsidence and sea level rise, by looking at Tokyo, Jakarta, Manila, and Ho Chi Minh City as case studies.
The multifaceted relationships that exist between communities and the environment in Fiji are increasingly threatened by the cross-temporal impacts of climate change. Recent literature on the relocation of vulnerable communities as a means to avoid slow-onset climate change impacts in Fiji highlights the complexity of these relationships and the range of considerations that must be factored in when assessing relocation options and strategies.
This paper presents challenges for water security in the three largest riverine islands in Asia, a socio-hydrology approach to manage water scarcity and human well-being, and an adaptive management cycle to implement socio-hydrology in the field.
Climate change requires joint actions between government and local actors. Understanding the perception of people and communities is critical for designing climate change adaptation strategies. Those most affected by climate change are populations in coastal regions that face extreme weather events and sea-level increases. In this article, geospatial perception of climate change is identified, and the research parameters are quantified.
Global climate change and land degradation are two grand changes facing humanity. In this perspective, we examine how degraded and abandoned farmland can be harnessed to fight climate change. Building upon and extending natural climate solutions, we suggest that the carbon capture and storage of abandoned farmland can be accelerated and maximized through restoring the diversity of plant species, applying biochar to soil, and co-developing renewable energy such as solar power. The benefits of these approaches extend far beyond climate-change mitigation and land restoration.
Humans, through agricultural fertilizer application, inject more reactive nitrogen (Nr) to terrestrial ecosystems than do natural sources. Ammonia volatilization is a major pathway of agricultural Nr loss. Using a process-based dynamic model, Shen et al. show that ammonia volatilization from agricultural land in the US will increase by up to 81% by the end of this century due to climate change alone, posing threats to food security, air quality, and ecosystem health, but mitigation strategies are available.
Reductions in carbon emissions have been a focus of the power sector. However, the sector itself is vulnerable to the impacts of global warming. Extreme weather events and gradual changes in climate variables can affect the reliability, cost, and environmental impacts of the energy supply. This paper analyzed the interplay between CO2 mitigation attempts and adaptations to climate change in the power sector using the Long-range Energy Alternative Planning System (LEAP) model.
At the 21st session of the United Nations Framework Convention on Climate Change (UNFCCC, COP21), a voluntary action plan, the ‘4 per 1000 Initiative: Soils for Food Security and Climate’ was proposed under the Agenda for Action. The Initiative underlines the role of soil organic matter (SOM) in addressing the three-fold challenge of food and nutritional security, adaptation to climate change and mitigation of human-induced greenhouse gases (GHGs) emissions. It sets an ambitious aspirational target of a 4 per 1000 (i.e.
