Climate and water: New (and old) approaches to manage enduring issues


Jordan is one of the poorest countries in the world in water resources. While part of this is due to the region’s climate, this has been exasperated by modern population and economic growth. Climate change is also blamed for some of this problem. Management responses have led to various solutions such the building of more dams, increased groundwater extraction and increasing reliance on non-renewable groundwater. Increasing needs have led to a number of ecological disasters as well as skyrocketing costs of pumping from increasingly deep and distant sources. Future plans are for even more expensive and implausible resources.

For the last two decades, the lecturer has been exploring alternative water resource approaches. These are based on two basic (and interlocking) premises. The first is that a sustainable approach for water management should begin with a holistic understanding of the hydrological cycle. Specifically, it is estimated that over 95% of rainwater that falls on the country evaporates before that it could be used. It would be highly valuable to understand a way to capture more of this water even marginally better than now. The second premise is that ancient water management practices have allowed for flourishing societies under similar climatic conditions that exist today. This implies that these practices should be considered as part of a management strategy that involves sustainable management and lower energy use. A major component of the management strategy relies on terracing, which fittingly relies on the aforementioned first premise. Terracing has shown to have the additional value of soil conservation and flood control.

Deposits related to some of these ancient water managements systems have the additional value of providing evidence for climatic conditions at the time. In addition, palaeowaters found in deep aquifers also provide additional evidence.

In this presentation, an outline of the relevant projects will be given and how the use of geological and archaeological approaches can help deal with the dilemmas facing arid areas around the world related to water management and climate change.
