Uzunkopru, is the second largest population among the districts of Edirne after Kesan, and is a district that hosts the agricultural social structure of Thrace and has other similar characteristics. Uzunkopru is known by the same name as the bridge at the entrance of the city. The Ergene River has made a significant contribution to the historical development of the city. The city, which was established on the riverside during the Ottoman period, followed a development process parallel to what the river added to agriculture and the city.

The most important problem in Uzunkopru is the pollution of Ergene. The pollution in the river, which originates from the Yildiz Mountains, cuts horizontally through Thrace, merges with the Meriç River and flows into the Aegean Sea; negatively affects the agricultural production, economic activities and therefore the social life in the district. Preventing pollution and reducing the damage caused by pollution will make a great contribution to increasing the economic and social vitality in the settlements around the Ergene River.

Uzunkopru is located in the middle of Lalapasa, Suloglu and Meric districts and is the most preferred center by the people in these districts after Edirne. Having the third largest population after Edirne Center and Kesan and the economic vitality it hosts are the most important indicators of this situation.
