Situated in Southeast Europe, Prespa forms a single high-altitude tri-border basin shared by Albania, Greece and North Macedonia. The basin covers a total area of 1 519 km2 and encompasses two interlinked tectonic Lakes – Great and Lesser Prespa – and their surrounding mountains. Nevertheless, unsustainable human practices in the basin bring about deterioration of natural resources. Main threats to the ecosystem include: water and soil pollution, deforestation, soil erosion, depletion of fish stocks and biodiversity loss (TDA, 2009). Considering that the main challenge in protection of the environment in Prespa Lake basin is the man-made inputs on pollution of the waters in the lake, in the past period the projects and initiatives that have been undertaken were mainly aiming at the reduction of agricultural inputs achieved through the shift to more environmentally friendly methods of cultivation. These initiatives were related mainly to the bean monocultivation in Greece and the introduction of Good Agricultural Practices in apple production in the Republic of North Macedonia. Unsustainable agricultural, fisheries, water and forest management practices are causing stresses on the ecosystem health of the Prespa Basin. Even though a lot of projects and plans have been made for protection of Prespa lake starting with the UNDP programs and programs from other donors as EU and Swiss Agency for Development, the lake is still suffering from pollution and eutrophication. On the other side of the border, in the Small Prespa Lake very few concrete measures have been taken for its protection. Small Prespa Lake is part of National Park of Prespa (NPP) in Albanian, stretched in Balkan Peninsula to the South East Europe and is shared between Albania and Greece. Prespa Lakes, Great and Small, are among the oldest and highest tectonic lakes of Europe. They are located about 850 m above the sea level and are surrounded by high mountains above 2000 m. The reed invasion in Small Prespa Lake occurs due to deviation of Devoll River toward Small Prespa
Lake during communist era, with purpose to collect water during the winter and to use it during the summer for irrigation of Korça field. Bad design and malfunction of decantation leads to accumulation of alluvions in
lake’s bed. Considering that the water from Small Prespa Lake is flowing in to the Big Prespa lake, bringing the pollution also there, concrete actions are needed to be undertaken as to protect both of the lakes.
