Climate change as an opportunity for future urban landscape design

In most parts of the world, the climate of the earth is getting warmer. Additionally, the pattern and the amount of precipitation have changed. Climate change is a significant challenge for urban planners, urban designers, architects, landscape architecture and all the professionals to pursue sustainability. On the other hand, climate change helps to free up conventional thinking, by making people come to terms with the idea that the future will not be the same as the past. Urban landscapes indicate a critical role in supporting urban “ecological and social” system. Besides important environmental services, urban green spaces provide “social and psychological services”, which are extremely important for the live ability of modern cities and the well-being of urban residents. Climate change will cause a profound effect on physical and biological phenomena and processes across the range of spatial and temporal scales. Throughout the past twenty years, there has been much attention directed towards the design of structurally diverse and species-rich natural vegetation for utilization in urban areas. Planting based on ecological concepts are using species which are well-fitted to the local environment to create natural and semi-natural vegetation. Achieving the desired aesthetic impression over a long season can only be attained if a combination of native and exotic species is used, in particular, when a country has a very limited native flora. This combination needs to be functional and also to address the aesthetic needs of urban landscape. Now days according to the climate change, the plant species boarders are not the same as the past and exotic species are going to be more fitted in the future.it can not only reduce management costs but also create new visual forms in urban landscapes.
