Urbanization trends and groundwater issues in Asian cities

Indonesia, Japan and Malaysia are other three rapidly urbanizing countries in Asia. The analyses are drawn based on a critical review of previous studies conducted on the topic in Asia. The study has found that most populous mega-urban regions in the world and in Asia are located in these five countries. The urban growth rate of China is double or little less than India, Indonesia and MalaysiaJapan is expected to exhibit a declination in its urban population while continue to maintain a high urbanization level during 2014-2050. Urbanization in Asia is not environmentally sustainable and it puts huge pressure on groundwater resources, degrading its quality and quantity, raising concern for resultant land subsidence. India poses a higher pressure on its groundwater resources, followed by China, Indonesia, Japan and Malaysia. Innovative technological and governance solutions with given priority on infrastructural development and environmental conservation is required to tackle urbanization dilemma existing in Asia
