Yenişehir is one of the central districts of the Mersin metropolitan area, located on the Mediterranean coast, with a population of approximately 279,400 inhabitants. The district hosts Mersin University and combines a young, dynamic student population with a long-established and increasingly ageing community. This unique demographic structure generates social vitality and economic activity, while also creating growing pressure on urban services, infrastructure, and public spaces.
From a socio-economic perspective, Yenişehir ranks 33rd among 973 districts in Türkiye according to the Turkish Statistical Institute (TÜİK), positioning it among the most developed districts nationwide. Characterised by a highly educated population and strong human capital, the district serves as a major hub for commerce and services within the metropolitan area. Urban mobility is particularly intense along key transport corridors, reflecting high daily activity levels and accessibility.
Climatically, Yenişehir experiences a hot and humid Mediterranean climate. During summer months, especially in August when average temperatures exceed 29°C, high humidity significantly increases perceived temperatures and thermal discomfort. These conditions heighten vulnerability to Urban Heat Island (UHI) effects. Although annual precipitation levels are moderate, irregular rainfall patterns increase localised flood risks in certain parts of the district.
Yenişehir Municipality has been a signatory of the Covenant of Mayors since August 2020. In May 2023, the municipality finalised its Sustainable Energy and Climate Action Plan (SECAP), committing to reduce per capita greenhouse gas emissions by 41% by 2030 and to achieve climate neutrality by 2050. In this regard, Yenişehir plays a leading role among district municipalities in Türkiye.
Furthermore, under the 2030 Smart Yenişehir Strategic Plan, the municipality has adopted a comprehensive vision centred on digital transformation, data-driven governance, sustainability, and smart city development. The strategic plan prioritises strengthening data analytics in decision-making processes, advancing Local Digital Twin infrastructure, and developing AI-supported urban service models.
In line with this vision, the municipality is actively developing its Local Digital Twin approach. Microclimate analyses and climate simulations conducted using ENVI-met software enable neighbourhood- and project-scale modelling of temperature distribution, surface characteristics, shading effects, and green space interventions. These activities have significantly enhanced the municipality’s climate-oriented planning and analytical capacity.
Within this framework, Yenişehir has been selected as one of six pilot cities in Europe under the Destination Earth initiative, contributing to microclimate modelling and data-driven decision-support processes. In addition, the municipality continues its work under the NetZeroCities project, using the same modelling infrastructure to advance its objective of becoming a climate-resilient city.
