Do you have a clear picture of what science says about past and future impacts of climate change in your country? Do you know how this knowledge has been generated and how reliable it is? The newly released open climate impacts encyclopedia ISIpedia was designed to provide state-of-the-art climate impact information by translating the latest climate impact science into understandable and informative texts.

The farming of livestock to feed the global appetite for animal products greatly contributes to global warming. A new study however shows that emission intensity per unit of animal protein produced from the sector has decreased globally over the past two decades due to greater production efficiency, raising questions around the extent to which methane emissions will change in the future and how we can better manage their negative impacts.
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.
