  abstract = {{I}n the highlands of southern {C}olombia and northern {E}cuador, soils developed on volcanic ash deposits have specific properties: high water retention, high hydraulic conductivity and high carbon ({C}) contents. {T}he main role of the soils is to regulate the water available for the dense population living in the valleys. {S}oil properties and land use depend on their altitudes. {A}ny important modification of land-use change has a serious effect on soil properties and consequently the ecosystem properties such as water regulation and flood control. {T}his can be a threat for a city that relies on the ecosystem for its water supply, as is the case in {E}cuador's capital, {Q}uito.},
