THE NEED FOR MODERNIZATION OF LANDSCAPE STRUCTURES AND ITS IMPACT ON THE ENVIRONMENT IN AKMENĖ DISTRICT

Abstract

Drainage systems that ensure proper moisture conditions and reduce the risk of waterlogging are essential for agricultural productivity. However, many of these systems in Lithuania, installed in the second half of the 20th century, are outdated and require modernization. Insufficient maintenance and aging systems can lead to negative environmental consequences, such as soil degradation and water eutrophication. The need to modernize drainage structures arises due to increasing climate change impacts and environmental requirements. Effective modernization solutions, such as controlled drainage and innovative technologies, could reduce water losses, improve drainage functionality, and contribute to more sustainable agricultural development. In Lithuania, it is important to increase investment in the renovation of drainage structures to ensure long-term infrastructure functionality and competitiveness in agriculture.

In Akmenė District, the area of drained land amounts to 56,188.80 hectares, and the depreciation rate of drainage structures reaches 68.87%. The poorest condition of drainage infrastructure in 2025 is observed in the Papilė cadastral area, while the best condition is found in the Alkiškiai area. The methods used for the research include data selection and systematization, graphical data representation methods, and GIS analysis.
