This interdisciplinary project analyzes cities undergoing rapid transformation due to exponential economic growth (e.g. through tourism). The background is the modernization process taking place in water management in the context of urbanization and globalization in Asia. The focus of the project is on the small town of Leh in the Himalayas in India situated 3,500 meters above sea level. It has a population of nearly 30,000. Local agriculture used melt water from glaciers over centuries. In recent decades, the town has grown rapidly as a result of increasing tourism. The economic growth that coincided with this has been causing significant changes to the lifestyle of the local population. However, the town is situated in a semi-arid region and is facing serious environmental challenges today already because of a lack of water and sewage systems and waste disposal.
The aim of this study is to illustrate alternative urban development approaches that help adapt Leh’s water resource management to the changes triggered by socio-economic developments and climate change. This involves application of various methods, as well as surveys, analyses of public health data, mapping based on Global Positioning Systems (GPS), geographic information systems (GIS) and satellite images. Further approaches include stakeholder workshops and capacity development.
The study shows that pollution of drinking water resources due to a lack of adequate sewage infrastructure presents a health risk for people in Leh. A further issue is that uncontrolled discharge may overtax groundwater resources. This study advocates an integrated approach to urban development and a decentralized or hybrid sewage system to preserve water resources, promote energy efficiency and reduce health risks. Leh can hence serve as a model eco-town for the region.
