Impacts World 2017

This international conference on climate-change impacts brings together scientists and stakeholders to shed light on the true costs of climate change. A number of IIASA researchers will present their findings.

The focus of the conference, which is hosted by the Potsdam Institute for Climate Impacts Research (PIK), is "Counting the true costs of climate change." It will center around four challenges: How to count the economic costs of climate change; Climate change and human health; Climate change and human migration and Climate change and the Sustainable Development Goals.

A number of researchers from across the institute's nine research programs will take part, bringing results and scenarios to help inform policymakers. IIASA has a broad range of research on climate impacts, including how it will affect agricultural production, water resources, and loss and damage due to unavoidable risks. IIASA also co-organized an important model intercomparison project focused on climate impacts, the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP).

IIASA participation

Workshop C1: Costs of CC and the Loss & Damage Mechanism 
Wednesday 11 October, 16:00
Defining the Risk and Policy Space for Loss and Damage: A Broadening Role for Climate Risk Analysis
Reinhard Mechler
Coauthor: Thomas Schinko

In the run-up to the Paris negotiations and thereafter, there has been heated debate as to what the Loss and Damage debate should cover. Some analysts and observers suggest it should provide tested risk management measures including technologies to those that are in dire need for support due to increasing climate-related risk, while others suggest compensation is to be considered.

Workshop C5: Comparing methods for assessing climate impacts 
Wednesday 11 October, 16:00
Economic costs of reduced water availability under climate change: Application of IIASA global hydro-economic modeling framework

Coauthors: Simon Parkinson, Peter Burek; Yusuke Satoh, Simon Langan,  Yoshihide Wada

Global water withdrawals for beneficial purposes have been increasing substantially in the last century, driven by the growth in population and income. The ensuing damages have been building up rapidly during recent years, with many basins around the world undergoing pervasive water scarcity conditions.

Workshop C7: Climate Change & International Trade - Channel for Damage Propagation or Chance for Adaptation? 
Wednesday 11 October, 16:00
Evaluating the Effects of Climate Change on U.S. Agricultural Markets: Sensitivity to Regional Impact and Trade Expansion Scenarios
Petr Havlik 
Coauthors: Justin S. Baker, Petr Havlík, Robert Beach, David Leclère, Erwin Schmid, Hugo Valin

Previous climate change impact assessments of the domestic agricultural sector have relied in part on domestic partial equilibrium models of the agriculture and other land use sectors. While such models often provide substantial detail on domestic production systems needed for climate impact assessments, these tools typically hold agricultural supply functions fixed in the rest of the world.

Workshop C8: Socio-economic consequences of climate extremes and compound impacts 
Wednesday 11 October, 16:00
Global assessment of exposure and vulnerability of the world’s poorest to hydro-climate risks under different socioeconomic projections
Ed Byers

The Shared Socioeconomic Pathways (SSPs) provide a framework and projections for assessing scenarios of socioeconomic change alongside climate impacts and options for mitigation and adaptation. The development of spatial socioeconomic datasets now facilitates impacts and vulnerability assessment from climate impact models.

Workshop S8: AgMIP and the SDGs: Simulating Multiple Demands on Agriculture 
Friday 13 October, 11:00am

Hotspots of future land use change impacts on terrestrial biodiversity under global mitigation scenarios
David Leclere
Coauthors: Támas Krisztin, Petr Havlík, Stefanie Hellweg, Fulvio Di Fulvio, Michael Obersteiner

Terrestrial biodiversity is declining at alarming rate, and the land use and land cover changes are the primary drivers of such trends. This issue is getting increasing attention, for example via the Sustainable Development Goals (SGD15, Life on Land). Over, as illustrated by other SDGs (e.g., SDG2 Zero hunger, SDG6 Clean water and sanitation, or SDG13 Climate Action among others), land use is at the center of many challenges for the coming decades.

Workshop S9: The role of mitigation and adaptation in securing SDGs under climate change
Friday 13 October, 11:00am
Wicked trade-offs between environmental SDGs and food security
Michael Obersteiner
Coauthors: Brian Walsh Stefan Frank, Petr Havlík, Matthew Cantele, Junguo Liu, Amanda Palazzo, Mario Herrero, Yonglong Lu, Aline Mosnier, Hugo Valin, Keywan Riahi, Florian Kraxner, Steffen Fritz and Detlef van Vuuren

The 17 Sustainable Development Goals (SDGs) call for a comprehensive new approach to development rooted in planetary boundaries, equity, and inclusivity. The wide scope of the SDGs will necessitate unprecedented integration of siloed policy portfolios to work at international, regional, and national levels toward multiple goals and mitigate the conflicts that arise from competing resource demands.


Impacts World is the leading international conference covering the diversity and depth of climate-impacts research today. IW2017 follows on from the inaugural Impacts World 2013, held in Potsdam, Germany, which brought together impacts researchers and stakeholders from across the spectrum of impacted sectors, initiating an era of truly integrated cross-sectoral climate-impacts research. 

Impacts World showcases not only the very latest in our scientific understanding impacts of climate change, placing a particular focus on the most pertinent and pressing political questions of the day, but shines a spotlight on the challenges that lie ahead for this research community, and offers ample time for in-depth discussions and dedicated working groups. In 2017, the confrence will be dedicated to counting the true costs of climate change, by considering four key challenges for aggregating and quantifying climate-change risks and impacts.
