Social and policy simulations, as well as serious games, are participatory processes through which diverse societal stakeholders collectively explore a complex reality and complex challenges. These participatory processes combine both social and natural science insights to foster experiential learning. They enable participants to make sense of the complexity associated with policy issues, and reflect on system inter-linkages and stakeholder plurality. These methods have become increasingly recognised for informing and guiding policy in complex settings, including sustainable development, climate change mitigation/adaptation and disaster risk reduction.

This Scenario Explorer presents an ensemble of quantitative, model-based climate change mitigation pathways underpinning the Special Report on Global Warming of 1.5°C (SR15) by the Intergovernmental Panel on Climate Change (IPCC) published in 2018. The ensemble was also used and extended in the IPCC's Special Report on Climate Change and Land (SRCCL, 2019). 

The CD-LINKS consortium has developed a set of consistent national and global low-carbon development pathways that take current national policies and the Nationally Determined Contributions (NDCs) as an entry point for short-term climate action and then transition to long-term goals of 1.5 and 2°C as defined by the Paris Agreement. 

The IPCC AR5 Scenarios Database documents the long-term scenarios as reviewed in the Fifth Assessment Report (AR5) of Working Group III of the Intergovernmental Panel on Climate Change (IPCC).

A database of greenhouse gas emission mitigation scenarios.

An exploratory research and resulting scenario about how far transformative changes on the energy end-use side can lead to.

A database with scenarios from the integrated assessment community to expedite climate change assessments.

The AMPERE database, operated by IIASA for the AMPERE consortium, hosts the model results for work packages 2, 3, and 5, as well as the results from the model diagnostics project. AMPERE scenario data were used in a series of research papers, which were published in a special issue of Technological Forecasting and Social Change as well as other journals. In addition, the results were used in the 5th Assessment Report of Working Group III of the IPCC.

The Global Energy Assessment (GEA) Scenario database documents results and assumptions of the GEA energy transformation pathways that underpin the GEA. The database serves as a central data repository for the dissemination of GEA scenario information.

The LIMITS Scenario database, operated by IIASA for the LIMITS consortium, hosts the results of the LIMITS modeling comparison exercise. The LIMITS project aims at advancing the understanding of the implementation of climate policies consistent with 2 degree Celsius. The main objective of the project is to provide an assessment of the emissions reductions strategies at the level of the world and the major global economies.

An interactive Web-based scenario analysis tool which allows the assessment of multiple energy access policies.

An interactive Web-based scenario analysis tool which allows the concurrent assessment of multiple energy objectives.

A modeling approach to improve financial disaster risk management

A model for studying the ecology and evolution of plant communities

A tool for exploratory statistical analysis on land use data.

A software tool to to aggregate several probability distributions into a single integrated one.

SHELscape is a spatially-explicit agent-based model for understanding short-run post-natural disasters non-linear adjustment processes in a multi-market framework.

The GROW Citizen Observatory was developed in a Horizon 2020 funded project to engage citizens (interested in growing food and improving the health of their soils) in sharing their data with a large community of growers across Europe.

Geo-Wiki is an online application for the visualization and crowdsourcing of land cover and land use data, where the first data collection campaigns ran during 2011 and 2012.

Data on agricultural field size has been collected via Geo-Wiki campaigns, where this type of data can provide some indication of agricultural practices, and it helps us to determine what types of satellite data are needed for agricultural monitoring in different parts of the world.
