Sustainable infrastructure: water, energy, transport

The importance of infrastructure is often only recognised when it is lacking. Infrastructure enables an economic upturn and therefore provides an important basis for better living conditions. Water, energy and transport are the source, carrier and motor of development.

Water is a source of vital nutrients and the basis for hygiene. But it is an economic good and production factor, too. Access to this essential resource and to good sanitation is essential for health, peaceful coexistence and productivity.

Dynamic development thrives on ecologically sustainable energy resources that can be accessed where they are needed – in private households, agriculture, industry and in the service sector.

An effective transport system is the backbone of every modern economy. It gets people to their place of work, to school and college and brings them to doctors and hospitals. Furthermore, it also opens up rural areas for development and makes cities internationally competitive.
