In the era of the devastating impacts of climate change, many cities around the world make strenuous efforts to find suitable and sustainable adaptation strategies to address the climatic dangers. In the past decades, Baghdad city witnessed an increase in the intensity of surface urban heat island (SUHI) as a result of the change in land cover and population density. By reviewing the related literature, it was found that many studies discussed SUHI intensity and causes, yet there is limited knowledge concerning the adaptation to such a phenomenon. In general, urban green infrastructure (UGI) represents a vital sustainable strategy that can achieve climate change 'adaptation and mitigation' simultaneously. Accordingly, the purpose of this study is to assess the effectiveness of UGI in reducing SUHI in Baghdad city. Risafa municipality was selected as a case study, as it suffers from a high level of SUHI risk. Using a computer climatic simulation program; ENVI-met, the temperature of different surfaces in the study area was assessed, and two typical models were selected. Surface temperature (Ts) of different points in these two models was measured according to the base case scenario and to three proposed scenarios of UGI. The results show that UGI has an apparent role in declining Ts in both models. It was also found that the cooling effects of injecting UGI scenarios in similar surfaces of the two models are convergent. This confirms the UGI great effectiveness in reducing SUHI in Baghdad City. It is also found that the effectiveness of UGI in cooling the existing surfaces depends on the original condition of the surfaces and the intensity and types of the injected UGI assets.

在气候变化带来毁灭性影响的时代，世界各地的许多城市都在努力寻找合适和可持续的适应战略来应对气候危险。在过去的几十年里，由于土地覆盖和人口密度的变化，巴格达市见证了地表城市热岛（SUHI）强度的增加。通过查阅相关文献发现，许多研究讨论了SUHI的强度和原因，但对这种现象的适应知之甚少。总的来说，城市绿色基础设施 (UGI) 代表了一项重要的可持续战略，可以同时实现气候变化的“适应和减缓”。因此，本研究的目的是评估 UGI 在减少巴格达市 SUHI 方面的有效性。里萨法市被选为案例研究，因为它遭受高水平的 SUHI 风险。使用计算机气候模拟程序；ENVI-met，对研究区不同地表的温度进行了评估，选择了两个典型模型。这两个模型中不同点的表面温度 (Ts) 是根据基本情况和 UGI 的三个建议方案测量的。结果表明，UGI 在两种模型中对 Ts 的下降都有明显的作用。还发现在两个模型的相似表面中注入UGI场景的冷却效果是收敛的。这证实了 UGI 在减少巴格达市的 SUHI 方面非常有效。
