Water is the foremost and most ancient element on earth, the one that contributes to the whole ecosystem existence, including human life and activities. While not limiting the attention to water consumption, the effects of climate change are demanding a re-think of strategy for sustainable water management, focusing on all the factors that make water such a complex and vital element for the entire ecosystem and life.
Through its agencies and projects, such as FAO and the UN Global Compact (CEO Water Mandate), the United Nations is promoting accurate information on water distress and water stewardship in order to ensure water security in different geographies of all the planet, which are experiencing water distress each one in their own way.
The real estate sector will be challenged by the dramatic effects of water distress, as it is part of the solution and needs to take a proactive approach on the issue. This can be represented by the 3 Rs applied to water management, namely reduce, reuse, recycle in order to promote water conservation.
From the risk of extreme events such as floods or extreme drought, real estate can first protect the environment and its assets by collecting data on water consumption and conducting analysis on ordinary and
extra-ordinary consumption, and act upon when required. In addition to improving data metering, concrete action involves putting the building itself at the centre of the solution : from permeable pavements to bioswales and green roofs, green infrastructure is one of the tools improving resources such as water.
