Deltas and Climate Change News

Climate Change: Ocean Warming Underestimated To date, research on the effects of climate change has underestimated the contribution of seawater expansion to sea level rise due to warming of the oceans. A team of researchers at the University of Bonn has now investigated, using satellite data, that this effect was almost twice as large over the past twelve years than previously assumed.

Publication: Hydraulic engineering in the social-ecological delta: understanding the interplay between social, ecological, and technological systems in the Dutch delta by means of “delta trajectories” Several of the world's largest deltas have recently been conceptualized as social-ecological delta systems. Although such conceptualizations are valuable in emphasizing complex interaction between social actors and ecological processes in deltas, they do not go into specific dynamics that surround technological developments in the hydraulic domain. By drawing from concepts originating in socio-technical systems research, we stress the importance of technology, particularly the domain of hydraulic engineering, in shaping a delta’s future. Based on two geographically distinct cases of flood management infrastructure in the Dutch delta, we demonstrate the influence of existing hydraulic works, in mutual interaction with social responses and environmental processes, on the development of the congregated delta system over time. The delta trajectory concept is introduced as a way to understand the interplay between social, ecological, and technological systems in deltas. We discuss options to realign unsustainable pathways with more desirable ones. Adaptive delta management presents a policy environment where these messages may be picked up.

Coastal zones: a methodology for the regional risk assessment of climate change impacts Several decision support systems were developed in recent years to encourage climate adaptation planning in coastal areas, especially at a national to global scale. However, few prototypes are easy to use and accessible for decision-makers to evaluate and manage risks locally. In a paper recently published on Ocean & Coastal Management, a team of authors presented a Decision Support System for coastal climate change risk assessment that implements Multi-Criteria Decision Analysis and Geographic Information Systems.

Long-term observations hold the key to climate change impact assessment Most ocean data sets are far too short for the accurate detection of trends resulting from global climate change, according to research published in the journal Global Change Biology. This study will help to make decisions about where, and for how long, we should monitor the ocean in order to spot climate trends in ocean biology.

Climate change is altering Greenland ice sheet, accelerating sea level rise The Greenland ice sheet has traditionally been pictured as a sponge for glacier meltwater, but new research has found it's rapidly losing the ability to buffer its contribution to rising sea levels, say researchers. They have also found that climate change has caused meltwater from lower elevations to run directly into the sea. / York University, Monday 4 January 2016
A Delta Atlas for a safer Bangladesh Hasse Goosen from Alterra, Wageningen UR has created an interactive Delta Atlas bringing into focus the various delta-related problems in Bangladesh. The Atlas is meant in particular to raise awareness, being the first step in a solution-oriented process of achieving a safer Bangladesh.

Inclusive Green Economic Development for Resilient Deltas and River Basins Inclusive and sustainable economic development is essential to strengthen the resilience for current and future challenges in river basins and deltas worldwide. This fits in the mission of Wageningen UR “to explore the potential of nature to improve the quality of life” and Delta Alliance’s mission to “improve the resilience of the world’s deltas”. With this workshop we would like to take the lessons learned from public and private funded projects to a next level.
