The World Aging Data Explorer (WADE)

WADE provides easy access to the innovative dynamic metrics of aging developed at IIASA. These metrics take the changing characteristics of people into account, thereby providing policymakers, researchers, and educators with a view of aging appropriate for our changing demographic environment. All indicators are based on data from the UN’s World Population Prospects 2022 and 2024. They cover the period 1950 to 2100 and are disaggregated by region, subregion, and country. Both types of indicators can also be produced with user-defined data.

Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS)

A model to assess emission and pollution reduction strategies that combat air pollution and climate change simultaneously.

Tools for Assessing Incentive Mechanisms

Ensuring that common goods and open-access resources—everything from clean air and the global climate to the internet and civil security—are equitably and fairly available to everyone requires incentive mechanisms.

Data from Geo-Wiki Campaign on Built-up Surfaces

Data on built-up surfaces around the world were collected via a Geo-Wiki campaign, where this data set is intended for use as an independent validation of global maps of built-up surfaces.

Postharvest Storage App

The Postharvest Storage App is a tool for collecting information on the types of storage mechanisms used by farmers for storing their harvests.

Collaborative Systems Mapping of Sustainable Pathways Method (COSMOS Tool)

Guidebook for designing and running in-person workshops.

Energy Multi-Criteria Analysis Tool (MCA)

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

Global emission fields of air pollutants and GHGs

A host of scientific chemistry and climate model experiments explore responses of the global atmosphere and climate systems to possible future changes in emissions of air pollutants and greenhouse gases. The Pollution Management research group (formerly AIR program) has used its GAINS model to develop a set of global emission fields of nine substances that provide consistent sets of future sectoral emissions for well-specified assumptions on economic development and the effectiveness of dedicated emission control policies.

Primary, Final and Useful Energy Database (PFUDB)

A historical database of energy use by country or region, energy level, sector, energy carrier, and end-use type.

Data from the First Geo-Wiki Campaigns

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.

Large Community-Evolution Models (LCEMs)

The complexity and dynamical nature of community interactions make modelling a useful tool for understanding how biodiversity patterns in communities develop over time and how they respond to external perturbations.

Logistic Substitution model II (LSM2)

The "IIASA Logistic Substitution Model II" (LSM2) is a software tool to estimate the parameters of technological growth and substitution processes. Applications include marketing research, scenario development, historical transition analyses, as well as meta-analysis across many individual technologies.
