Distinctive features of water resource use in the Danube-Black Sea hydrographical space (Republic of Moldova sector)

The Danube-Black Sea Hydrographic Space, spanning 6,500 km² or 19.2% of Moldova, includes the river basins of Ialpug, Cogâlnic, Sărata, and Hadjider. This region faces considerable challenges due to its limited water resources and its predominantly agrarian and rural character. This study examines the distinctive aspects of water use in Danube-Black Sea Hydrographical Space, assessing its role in Moldova’s overall water supply and the factors affecting its efficiency. The research employs statistical, deductive, comparative, and cartographic methods, utilizing data from the Moldovan Water Agency, the Inspectorate of Environmental Protection, the National Bu- reau of Statistics, and the Moldova Water-Canal Association, in addition to watershed management plans and relevant analytical studies. The Danube-Black Sea Hydrographical Space contributes minimally to the water supply of the Republic of Moldova, with over 85% of water sourced from groundwater due to the poor quality of surface water. Water use in the region is primarily agri- cultural (58%), with 30% allocated for domestic purposes and only 3% for industrial use. While there has been an increase in water use for technological and domestic needs, agricultural water use shows fluctuating trends. The region’s strained water resources call for improved management strategies to address its hydrological characteristics and the impacts of climate change, ensuring sustainable water use and supporting local economic and environmental needs.
