Urbanization and Climate Change
نویسنده
چکیده
Cities are at the centre of Asia-Pacific’s economic growth and development. They provide the environment and social milieu in which more and more people live. Urban areas in the region, though containing around 42 percent of its population, account for 80 percent of the region’s GDP1. Urbanization in Asia and the Pacific is proceeding at a scale and speed unprecedented in human history. It took 210 years for urbanization rates in Latin America to rise from 10 to 50 percent. Asia and the Pacific as a whole will take only 95 years to achieve the same level of urbanization, some countries in the region will require less than 60 years2. While Asia-Pacific hosts over half of the world’s 20 megacities3, over 60 percent of the region’s urbanites live in urban areas with populations of less than 1 million, often experiencing higher population growth rates than primary cities4. Secondary cities also act as local economic growth centres, markets and processing centres for rural products, and bridges between rural areas and large urban centres. Yet most of them lack basic infrastructure and services, as well as inclusive urban management capacity. Most have not developed global or even national linkages and are struggling to accommodate growing populations, lag in job creation and have weak revenue bases.

Climate change, urbanization and disease: summer in the city…
Climate change and urbanization can alter the burden of human diseases. The tropics, a region that includes the poorest populations and highest disease burdens, are expected to get slightly hotter and substantially more urban. Studies have projected changing burdens under different climate or urbanization scenarios, but it remains unclear what will happen if both happen at once. Interactions co...
متن کاملForecasting the combined effects of urbanization and climate change on stream ecosystems: from impacts to management options
Streams collect runoff, heat, and sediment from their watersheds, making them highly vulnerable to anthropogenic disturbances such as urbanization and climate change. Forecasting the effects of these disturbances using process-based models is critical to identifying the form and magnitude of likely impacts. Here, we integrate a new biotic model with four previously developed physical models (do...
متن کاملPrediction of Climate Change Induced Hydrogeomorphology by using SDSM in CAN Watershed
Climate change is one of the most important challenges that has affected various parts of human life on Earth. In the present study, in order to investigate the climate change, three synoptic stations of Karaj, Mehrabad and Dashan Tepeh with the help of the statistical statistic downscaling model (SDSM) model were used to predict the statistical period of 2016-2045. Finally, the effects of clim...

How is urbanization altering local and regional climate ?
Urbanization has profound effects on climate. The materials and morphology of the urban surface, along with emissions from domestic, commercial and transport activities, result in changes in local climate often greater in magnitude than projected globalscale climate change. Cities are commonly 2-3 °C warmer than their surrounding environments, with the greatest differences at night and in winte...
