Water, the scarcest natural resource in the Middle East, has always been a touchy subject in the region. ‘Water policy’ within and between nations has long determined each one’s approach to satisfying local and regional water demands. As water demands escalate at alarming rates, access to adequate supplies to meet ever growing populations, new business developments and the essential food production industry have and will continue to shape foreign policy within the region. Now, environmental considerations are having a deep impact on how countries develop their entire water and wastewater infrastructures. Norrie Hunter takes a look at recent developments and future plans for the area. 13 August 2009
Dr Mike Coffey looks at how river water quality can be assessed objectively and considers how successful environmental regulations related to river and associated water streams have been in the UK, especially when dealing with difficult residual pollution problems. 13 August 2009
The development of the coastal environment is taken for granted in most of the developed world. In this article, we examine how managers can protect the fragile environment by looking at emission controls, and include an overview of current strategic management approaches which seek to combine water quality controls with wider marine environment protection goals. 24 June 2009
Working with Water spoke with David Waggonner, principal at Waggonner & Ball Architects, about the importance of integrating water into the city structure of New Orleans. Leading the rebuild of the water damaged city is a challenge – not only must lessons be learned from existing and temporary infrastructure and political failures, but successful processes elsewhere in the world must be integrated with the uniqueness of New Orleans. 12 May 2009
