By applying the multi-state model of population dynamics, including differential fertility, mortality and migration rates, the IIASA Population and Just Societies Program has produced projections of the European and Asian population by age, sex and four levels of educational attainment, as well as population projections by age, sex, and level of educational attainment for the world. Additionally, new measures of aging, developed at IIASA, are presented for the world and world regions, and individual countries.
Model
The linkage algorithms solve the problem of linking models, e.g. sectorial and/or regional, into an inter-sectorial inter-regional integrated model. Linkage enables to avoid “hard linking” of models in a single code, which saves the programming time and enables parallel distributed computations of individual models instead of a large scale integrated model. Models linkage preserves the structure of the original models taking into account critically important details, which are usually missing in aggregate models.
Dataset
Stochastic Quasi-Gradient (SQG) methods have been developed for solving general optimization problems without exact calculation of objective function and constraints (let alone of their derivatives). SQG methods enable a sequential revision of approximate solutions towards the optimal using newly acquired information on the system, obtained via either direct on-line observations or(and) simulations.

Can cooperation across sectors and countries help to achieve sustainable development? How do stakeholders in the Indus and Zambezi basins envision the future and how can they make that future a reality? IIASA researchers looked into these questions as part of a large-scale initiative with international partners.

World Water Day held annually on 22 March, celebrates water and raises awareness of the 2.2 billion people living without access to safe water. It is about taking action to tackle the global water crisis. A core focus of World Water Day is to support the achievement of Sustainable Development Goal (SDG) 6: Water and sanitation for all by 2030.

Solar energy is a clean, renewable source of electricity that could potentially play a significant part in fulfilling the world’s energy requirements, but there are still some challenges to fully capitalizing on this potential. Researchers looked into some of the issues that hamper the uptake of solar energy and proposed different policies to encourage the use of this technology.

Nadejda Komendantova from the Cooperation and Transformative Governance group is invited to provide an opening keynote presentation at the VIII International Workshop on Critical Infrastructures in the Digital World. The aim of the workshop is to discuss theoretical and methodological issues of development and integration of intelligent, agent-based and cloud computing for contingency management in critical infrastructures as well as to talk about Situational Awareness, Semiotics, Visual Analytics, Semantic Modeling and Cognitive Graphics and their applications in critical infrastructures.
