The Ecological Consequences of Level Changes in Lake Van
(Maik Nauka/interperiodica/springer, 2007) Deniz, O.; Yidiz, M. Z.
Measurements of perennial time scale in Lake Van, the biggest take with soda in the world, historical data, and the morphological changes in its coasts suggest that there is a continual rise in its level. The rise in the level of the lake which occurs under natural conditions averages 3.7 cm/year. This rate is not stable and it generally shows a parallelism in the fluctuations perennially. The measurements conducted in Tatvan show that this rise approximated to 2 meters (2.1 m) in 1944-2000. The swift rise, especially after 1987, has caused an environmental disaster in the coasts, inundating approximately 5200 hectares of land. Tens of villages together with Van, Tatvan, Ercis, Adilcevaz and Ahlat cities were affected, and thousands of houses, tens of thousands of acres of agricultural lands, highways, ferry harbour, historical sites, and wetlands in the mouths of streams, shelters of wild birds were damaged. In addition to all these, drinking waters, canalization network, urban infrastructure systems as well as some parts of Van Airport and many camping areas of holiday were reported to have been damaged due to the same reasons. In this investigation we aimed to determine the environmental consequences of level changes and the measures to be taken accordingly.
Turkey-Iran Border and Irregular Migration From a Geographical Perspective
(Routledge, 2025) Deniz, O.; Nargül, S.
The Turkey-Iran border, which is approximately 560 kilometers long and Turkey's second longest border after the Syrian border, has been at the forefront of irregular migration for many years. A mass of migrants, enters Turkey from here every year. This border is regarded as the most significant used by irregular migrants, mainly from Afghanistan, Pakistan and Iran to enter Turkey and then reach Europe through migrant smugglers. Considering the characteristics of the border, the topographical structure, climate conditions, historical ties between the populations living on both sides of the border, socio-cultural interactions, and economic conditions are important dynamics that ensure the continuity of irregular migration. In this study, the political formation process, the role of geographical factors, and the socio-cultural structure of the border will be discussed. Then, the impact of the geographical structure of the border line on irregular migration will be examined. In addition, the profiles of migrants entering Turkey, the magnitude of the migration, and the actors of irregular migration, particularly smugglers, will be thoroughly investigated. © 2025 Association for Borderlands Studies.
