Interdisciplinary Asessment of Sea-Level Rise and Climate Change Impacts on the lower Nile Delta, Egypt

by Rebecca Herrera

The Mediterranean region will continue to experience climate change in much of the same way as other arid regions around the world. Susnik et al. (2014) set our to find our how the Nile River delta in Egypt experiences more intense droughts and water shortages, rising regional temperatures, an increased frequency of flash flood events, and sea level rise. It is critical to understand of how these climactic changes will impact the people residing in the delta. Susnik et al. take an integrated and interdisciplinary approach to studying the effects of sea level rise (SLR) on the lower Nile delta and the greater Alexandria areas by analyzing the results of three complementary projects; which reveal that water overexploitation exacerbates land subsidence and accelerates saline intrusion of soils and groundwater which has radiating effects on employment as well as placing additional pressure on agricultural lands and regional development.

Modeling the effects of Urbanization on Local Climates in the Pearl River Delta

by Rebecca Herrera

It has become clear that cities and other urban localities experience warmer temperatures than their rural counterparts. The urban heat islands of megatropolises can have more extreme effects on a specific area than global temperature rises have on the same area. This phenomena was studied by Wang et al. in the Pearl River Delta region of Southern China in the coastal zone of the Guangdong Province, an area that has experienced dramatic economic development over the last thirty years. The authors attempt to gain a more thorough and comprehensive understanding of the effects of urbanization on regional and local climactic indicators over an extended period of time. The results showed an overall average temperature increase, an decrease in daytime temperature ranges, a decrease in near surface water vapor quantities, a decrease in the annual number of precipitation days, an increase in annual precipitation, and a decrease in average wind speeds across urbanized zones.

Climate Change and Aging Population

by Yijing Zhang

According to Adapting To Global Change: Aging, Urbanization and Resilience by Francesca Birks and Katherine Prater, the demography has shifted towards an aging population across the entire world. The authors point out that as a relatively vulnerable group, the elderly deserve more help from the society, especially more from the government. Although the vulnerability of this population may not be apparent on daily basis, it will be exposed under extreme conditions, such as natural disasters like hurricanes and earthquakes. With the lack of medical materials and weak evacuation instructions, the vast majority of fatalities caused by Hurricane Sandy were the population over 45. When the Heatwave hit Moscow, the outcome of the forest fire was the poor air quality. Among the entire population, the elderly are the most susceptible to these consequences. Therefore, Birks and Prater suggest the importance of design solutions to address this problem. Continue reading
