Most precipitation that falls on human settlements is lost to the atmosphere through evapo-transporation (evaporation plus transpiration of water taken up by plants), or runs into rivers away from settlements before it can be used. In some water-rich regions, particularly wealthy regions with centralized water infrastructure, these losses may not be a major concern. However, in many water-poor areas, small-scale collection infrastructure can contribute greatly to the volume of freshwater available for human use.

Description

As the concept and practices of a sustainable built environment have evolved over the years, it is increasingly recognised that the scope should be expanded beyond individual buildings to the community scale. Sustainable community design and practices refer to planning, designing, building, managing and promoting social and economic development of communities to meet sustainable development objectives.
