An integrated approach to the conservation of aquatic ecosystems of small reservoirs in the context of climate change.

Abstract

Small water reservoirs in southern Ukraine face numerous environmental problems that not only deteriorate their original condition but also affect Ukraine’s economy and the food security of its population. In particular, these problems include [1-5]:  waters of small reservoirs in southern Ukraine can be polluted by industrial and agricultural waste, municipal waste, and other anthropogenic impacts. This leads to a decrease in the water level in reservoirs, deterioration of water quality and threats to human and animal health;  eutrophication is the process of excessive vegetation growth in water bodies, which contributes to increased levels of nutrients such as nitrogen and phosphorus. This can lead to the development of algae and a decrease in the amount of oxygen in the water, which threatens the lives of fish and other aquatic organisms;  small reservoirs in southern Ukraine are often targeted by illegal fishing, which leads to a decrease in fish populations and threats to the biodiversity of aquatic ecosystems;  climate change can affect the water level and temperature in small reservoirs, which can have consequences for aquatic life and biodiversity
