The increasing world population demand for bioeconomy products intensify the nitrogen cycle and encourage eutrophication in water bodies. Global climate change and land use transformation have a significant impact on the hydrological cycle. Integrated water management in the catchment area is a sustainable solution for catchment area development and balancing economic and environmental interests. The aim of this study is to develop an optimization model for sustainable lake management. The case study is done in eu...

Land reclamation is an improvement of land, which reduces the adverse effects of climate conditions and ensures the sustainable use of natural resources. Latvia is in humid soil area, which means that soils are formed under wet conditions. During the spring and autumn, these soils are wetted and unsuitable for land treatment. The installation of drainage systems shall ensure the reception of excess humidity and its removal from agricultural land, which makes it possible to process the land and to carry out economi...

Balanced development of ecosystem services in regions is one way of achieving the UN's sustainable development goals. Ecosystem services are divided into three main groups: First delivery services. Nature supplies us food and drinking water, raw materials and alternative energy sources. Thanks to natural biodiversity, we can grow a variety of vegetables and fruit, gather berries and mushrooms in the woods, and fish in the sea, rivers and lakes. Nature also supplies drinking water, which is the source of life for e...

Changing climate variability and the type of land use are the main factors influencing the hydrological regime. The hydrological regime of the lake has a direct impact on biodiversity and has an impact on socio-economic processes in areas adjacent to the lake. The aim of the study is to predict and assess the impact of climate change and the change in the type of land use on the hydrological regime of Lake Usma. Two linear land-use change scenarios were used for modelling. Twelve climate scenarios were used to mod...
