Abstract
Abstract. With the rise in urban population comes a demand for solutions to offset environmental problems caused by urbanization. Green infrastructure (GI) refers to engineered features that provide
multiecological functions in urban spaces. Soils are a fundamental
component of GI, playing key roles in supporting plant growth, infiltration,
and biological activities that contribute to the maintenance of air and water
quality. However, urban soils are often physically, chemically, or
biologically unsuitable for use in GI features. Constructed Technosols (CTs),
consisting of mixtures of organic and mineral waste, are man-made soils
designed to meet specific requirements and have great potential for use in
GI. This review covers (1) current methods to create CTs adapted for various
GI designs and (2) published examples in which CTs have been used in GI. We
address the main steps for building CTs, the materials and which formulae
should be used to design functional CTs, and the technical constraints
of using CTs for applications in parks and square lawns, tree-lined streets,
green buffer for storm water management, urban farming, and reclaimed
derelict land. The analysis suggests that the composition and structure of
CTs should and can be adapted to available wastes and by-products and to
future land use and environmental conditions. CTs have a high potential to
provide multiple soil functions in diverse situations and to contribute to
greening efforts in cities (and beyond) across the world.
