Dust detectors in the Aral Sea basin

The Aral Sea repeatedly appeared and disappeared over the last century but has now steadily decreased as the dust increased, resulting in desertification. There is still water in the north of the Aral Sea but the ‘desert’ lakebed in the middle has more dust and sandstorms than anywhere else in the world. Researchers used two…

Climate change impact on river basins in Ukraine 2020

The researchers used six models comparing precipitation and drought based on river levels using RCP 2.6 and RCP 8.5 scenarios. Their predictions show a decrease in water in most of the eight main river basins, particularly between 2040 – 2070. The greatest reductions by the end of the century are predicted for Pripyat, Southern bug…

Catching raindrops in Primorye

Scientists at the Russian Academy of Sciences have developed mathematical models to predict flooding effects and assist with an action plan. To develop and test their models, they used flooding data from flooding in Primorye in 2001. They included the flooding area, water level, temperature and velocity. They also included human and animal populations in…

An unusually windy, high salt diet of the Arctic Ocean

An international collaboration with Obukhov Institute of Atmospheric Physics at the Russian Academy of Sciences monitored the causes, impacts of circulation and sea ice decline in the Arctic Ocean between 2000 – 2019. Sea ice decline, and atmospheric warming affect the distribution of fresh and saline water with the changing currents. The researchers created simulations…

Distilling hard and soft water strategies in climate adaption policies

Despite Russia’s rich freshwater resources, it faces significant water problems, which arise from the country’s adaptation policy with low priority to climate action and less advanced risk management. Safonov from NRU HSE, Moscow outlines the key characteristic of water-related problems in the world’s biggest country. Firstly, Russia is one of the world’s leaders in its…

Linking science and action – how to resolve water challenges in Central Asia

With its mixed continental climate, Central Asia faces unstable periods of draughts and rains. This has led to serious water shortages across the regions (Fig. 1) followed by escalating water-based conflicts between countries, increased hunger and threatened economics. However, despite the scientific progress and the continuous international effort, Central Asian water management institutes still rely on…

Detecting a methane rush over the Arctic seas

The Arctic is warming twice as fast compared to the rest of the World. The Arctic ocean contains gigatons of organic carbon and methane hydrates. Warming may induce liberation of this methane into the atmosphere. This greenhouse gas would start a positive feed-back: the warmer water – the faster methane emission, the higher concentration the…
