As also specified in ICAO Doc 9137-AN/898 Part 3 – Airport Services Manual: Part 3 Wildlife Control and Reduction document, a bird monitoring study has been continuing in order to determine the regions where the birds pose a flight safety risk and assemble in an area covering the airport and a zone of 13 km around the airport. In this context, it is ensured that the areas potentially attractive to birds are monitored, or arranged so as not to pose any risk, or do not form at all. In consequence of these studies conducted, it has been found out that Odayeri Solid Waste Landfill Area (SWLA) is an attractive area for seagulls, crows, starlings, storks, and several birds of prey. In much of the world, airports unfortunately coincide with dumping grounds. The reason is the desire to shift to a larger airport out of the city when the airport in the city becomes insufficient in terms of capacity.
However, the landfill areas that have already been positioned out of city due to reasons such as stink, view, health, etc. and the newly built airports are close to each other due to logistical reasons.
Closeness of landfill areas and airports is regarded as one of the main reasons of bird-plane collisions all over the world. However, that Odayeri SWLA, which is a very attractive region for birds and thus very risky for flight safety, has stopped receiving organic solid wastes and decided to construct a modern Domestic Waste Incineration and Energy Generation Plant instead in consequence of very close coordination of Istanbul New Airport Top Management with DGSAA, Ministries, Istanbul Metropolitan Municipality, and ISTAC can become a model for numerous countries that have the same problem in the other parts of the world.
