In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.

The International Association of Hydrogeologists (IAH) serves scientists, engineers and other professionals working in the field of groundwater resource planning, management and protection. IAH has two book series which are produced under the imprint of CRC Press in the Netherlands, part of the Taylor and Francis Group. IAH books have the common purpose of spreading the science and knowledge of hydrogeology and are products arising from IAH’s congresses and meetings, its commissions and networks, as well as a variety of other sources. Information is gathered from highly respected sources and include case studies, regional descriptions, analyses of sub-disciplines and outputs from major international programmes.
International Contributions to Hydrogeology
The second series, International Contributions to Hydrogeology, the ‘blue books’, includes monographs on sub-disciplines of hydrogeology as well as outlets for major international investigatory programmes and collections of papers within a broad theme of international interest.
The first series is the Selected Papers, often referred to as the ‘green books’. These are collections of papers derived from Congress and other meetings which normally, but not always, were sponsored by IAH. They may also be a collection of papers derived from a programme of investigation that again need not necessarily have enjoyed direct IAH involvement.
