Assessing climate change effects

Enhancing Society’s Understanding about Climate Change Effects on Lakes in Latvia (No. 2/EEZLV02/14/GS/006)

Over the last decades climate change induced increase in lake water temperatures in Latvia has led to intensive blooming of potentially toxic blue-green algae and a possible transfer of their toxins through the food chain, ending up in fish species used for human consumption. Nevertheless, there is not scientifically accurate data on this topic available and despite posing a potential threat to human health the general public remains uninformed about this problem.  To inform the local society about the possible negative climate change effects on lakes’ ecosystems and human health, the holistic study of the climate change and its impacts should be carried out, and the scientifically valid information should be obtained and distributed.


  1. To investigate the impact of intensive blue green algae blooming on the chosen demonstration lakes’ ecosystem functioning, stability and biodiversity.
  2. To inform local municipalities and different social groups on the progress and the outcome of the project.

Our Solution

IES is the principal contractor. A holistic survey of the impacts of climate change on two lakes’ ecosystems will be carried out. The research will be focused on the consequences of blue-green algae blooming. To evaluate the survey consisting of ecosystem’s food chain, physical-chemical characteristics, production and accumulation of blue-green algae toxins in the food-chains, researchers will use innovative methods.  To raise the awareness of the lake’s ecological situation and the impact of climate change on it, the project team will organize the communication and publicity activities for local municipalities, environmental professionals and broader society.4
