Definition of Sustainability
"Sustainability is a local, informed, participatory balance-seeking process, operating within a Sustainable Area Budget, exporting no harmful imbalances beyond its territory or into the future, thus opening the spaces of opportunity and possibility."
Sustainability is a local process: it happens at a specific place - the living environment of a settlement within its region, including living patterns and creativity of the tenants.
Sustainability is a participatory process: it needs informed, empowered, gender sensitive human actors who are the stakeholders in the sustainability negotiation process.
Sustainability is a balance-seeking process: it models alternative future scenarios, taking into account the classical triad of sustainability: economy, ecology, socio-culture , complemented by the context of built environment.
Sustainability creates spaces of possibilities: sustainability considers the future as an open space where socio cultural life quality, economic equity, and ecological needs converge towards balance.
