For a century eutrophication has been the most serious environmental threat to lakes in the densely populated or agricultural areas of Europe. During the last decades, however, major efforts have been used to reduce the external nutrient loading, not least from point sources. Despite these comprehensive efforts, lake eutrophication remains a major problem. Today, the highest pollution input is derived from diffuse sources mainly from agricultural land in lake catchments. We describe the actions taken to reduce the external nutrient loading and the lake responses to these actions as well as the use of additional methods to reinforce recovery, such as biomanipulation. We further discuss resilience and short and long-term responses. We highlight the Danish experiences, but add several examples from restoration measures taken elsewhere in Europe. We also briefly discuss how a potential change in climate may affect lake responses to diminished nutrient loading.

Evaluation of the best management practices in a semi-arid region with high agricultural activity Özcan, Zeynep; Kentel Erdoğan, Elçin; Alp, Emre (Elsevier BV, 2017-12) The arid and semi-arid regions with water scarcity are vulnerable to several stressors such as urbanization, high water demand created by agricultural and industrial activities, point and non-point pollution sources, and climate change. Hence, proactive policies and sustainable water management strategies that are based on decision support systems are crucial in arid and semi-arid regions. Because of large expenses and implementation difficulties associated with the diffuse pollution abatement plans, many a...
Bayesian estimation of crop yield function: drought based wheat prediction model for tigem farms Yıldırak, Şahap Kasırga; Kalaylioglu, Zeynep; Mermer, Ali (2015-12-01) Drought is one of the biggest threats that affects agriculture. Based on recent climatic observations and future projections, drought continues to increase its harmful impact on agricultural productivity especially in the arid areas of Turkey. Wheat farming in these arid and semi-arid areas such as Central Anatolia depends heavily on precipitation, thus monitoring for drought is needed. The timing of precipitation is also as important as its quantity. This study makes use of a crop and location specific mod...
CHANNEL DETECTION AND TRACKING FROM LIDAR DATA IN COMPLICATED TERRAIN Arghavanian, Azar; Leloğlu, Uğur Murat; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2022-2-04) Efficient management of water resources is of great importance regarding ever increasing population and water droughts related to climate change. Drainage networks are important geomorphologic and hydrologic features which significantly control runoff generation. Recently, it has been feasible to monitor the earth’s surface and natural phenomena with the aid of remote sensing techniques. However, very high spatial resolution is needed for monitoring small waterways and knowledge of accurate drainage pattern...
Climate change impacts on lakes: an integrated ecological perspective based on a multi-faceted approach, with special focus on shallow lakes Jeppesen, Erik; Meerhoff, Mariana; Davidson, Thomas A.; Trolle, Dennis; Sondergaard, Martin; Lauridsen, Torben L.; Beklioğlu, Meryem; Brucet, Sandra; Volta, Pietro; Gonzalez-Bergonzoni, Ivan; Nielsen, Anders (PAGEPress Publications, 2014-01-01) Freshwater ecosystems and their biodiversity are presently seriously threatened by global development and population growth, leading to increases in nutrient inputs and intensification of eutrophication-induced problems in receiving fresh waters, particularly in lakes. Climate change constitutes another threat exacerbating the symptoms of eutrophication and species migration and loss. Unequivocal evidence of climate change impacts is still highly fragmented despite the intensive research, in part due to the...
Climate change vulnerability in agriculture and adaptation strategies of farmers to climatic stresses in Konya, Turkey Kuş, Melike.; Rittersberger Tılıç, Helga.; Department of Earth System Science (2019) Agriculture is highly vulnerable to climatic changes and extremes as it is generally an outdoor activity. Its vulnerability to climate change is estimated at different scales and then policies are developed to reduce sensitivity and improve adaptive capacity of the farmers accordingly. Assessments at different scales use different methodologies and indicators, which result in incomparable outcomes. Macro scale assessments lack further validation of the results at the local level, and the local level assessm...
