Since times immemorial, man has modified his physical environment; it is a pressing matter, today, that such changes be henceforth made within the framework of a concerted land planning program. This is particularly necessary where estuaries, coasts, and littoral fringe are concerned. The geologist is called upon to play a primordial role in coastal regions management and planning. He or she must be included in the specialists team whose task it is to bring to a close the series of catastrophics which obliterated beaches and dunes, in areas scattered all over the world, while fostering a rational economic and industrial development.

Population migration to the coastal zone has increased by 50 to 70 per cent. Conflicts of inhabitation and use are escalating rapidly. Single use is economically risky if not unsound. In traditional societies multiple‐use has been exercised successfully. Concentration among today′s users should lead to an acceptable balance and to sustainable situations. Physical, biological and geological equilibria and conservation should be maintained. For this to happen communication approaches should be fine‐tuned.

Brownfields are commonly pictured as the hottest real estate property in the USA. Will the European market follow suit? Brownfields are properties long considered lost to re‐utilization due to their polluted condition. Federal and state governments in the USA provide incentives to foster redevelopment. But the risks involved still keep potentially interested parties clamoring for more legal protection. It may validly be asked whether recovery schemes may pose subsequent health or other problems. Communities involved may react quite differently; the attitude may be one of apathy, distrust or opposition, or, in sophisticated milieus, of realism. Much will depend on “education” and communication.

Coastal sections suffering from erosion generally show the common symptom of a lack of available sand to allow the build up of the natural coastal barrier. Soft methods of coastal protection, including beach nourishment, profile nourishment, feeder berms, compensation‐dredging, aim to tackle the problem at its source, i.e. by supplying sand to the system. When thoroughly designed, these methods are considered the best technical/economical and appropriate solutions.
Although EU directives were issued quite some time ago, implementation progresses slowly and at an unequal pace in Union member states. Certification of assessors, auditors and verifiers differs widely and is sometimes inordinately complicated; in some instances accountants have stepped into the “vacuum”, in others “certification” documents are issued by private organizations. Uniformity is far from being the rule. This paper takes Belgium as a case study. In opposition to what has developed in the USA where federal authority can be completed, even toughened by US regulations, but remained national (viz. federal), in our example responsibility has nearly entirely been devolved to the next (regional) level of authority. A survey was conducted of EMAS implementation in 11 European States: its results are disclosed and commented on.

Analysis of Information Options offers new tools for evaluating investments in research, mineral exploration, logistics, energy transmission, and other information operations. With Information Options, the underlying assets are information assets and the rules governing exercise are based on the realities of the information realm (infosphere). Information Options can be modeled as options to “purchase” information assets by paying the cost of the information operations involved. Information Options arise at several stages of value creation. The initial stage involves observation of physical phenomena with accompanying data capture. The next refinement is to organize the data into structured databases. Then bits of information are selected from storage and synthesized into an information product (such as a management report). Next, the information product is presented to the user via an efficient interface that does not require the user to be a field expert. Information Options are similar in concept to real options but substantially different in their details, since real options have physical objects as the underlying assets and the rules governing exercise are based on the realities of the physical world. Also, while exercising a financial option typically kills the option, Information Options may include multiple exercises. Information Options may involve high volatility or jump processes as well, further enhancing their value. This chapter extends several important real option applications into the information realm, including jump process models and models for valuing options to synthesize any of n information items into any of m output assets.
