Summary of issues discussed at the conference held in Belgrade, Sept. 1989; emphasis on Yugoslavian interests. Potential for cooperation in transport, tourism, environmental protection, and other areas.

Very first settlement after adaption of agriculture was around rivers. These river valley settlements have definite birth and extinction by various factors. They are the early settlements and starting point of urbanization. Any urbanization attracts migration due to opportunities created by social grouping. Tracing of Historical development in these settlements give clear picture of urbanization process. They also become places of study for human achievements in terms of architecture, urbanization, social, political and economic developments. Conserving these precincts for posterity becomes the prime necessity. These settlements are ignored in developmental process. Water conservation and distribution of scarce resource lead to complexities indecision making in projects. Frequent floods impacts on normal life. Planning in river valley, calls for addressing developmental process in multi layers of decision making involving various specialized agencies. Government needs advice on these issues by past experiences in similar situations. An attempt is made to understand these forces for conducive developmental process in changing times. Krishna valley region is chosen as it experiencing rapid migration tendencies and change of climatic conditions along with changing river course due to soil erosion and levels of water courses. This article Concludes in organizational and strategic decision making systems for positive development and conservation of settlements of historic value

"A study of the role of riverine shipping in Late Roman defensive strategy along the Danube (300-600 AD). This work follows and draws together current trends amongst ancient historians who take a more positive view than hitherto of the value of rivers as natural barriers and of the defensive qualities of late-Roman frontier units. The Danube frontier, which was more than 2,500 kilometers long, simultaneously presented both advantages and disadvantages to its defenders. The formation of a large number of well-equipped naval units tasked with monitoring and protecting the river banks moved the first line of defence forward from the region immediately behind the rivers onto the rivers themselves. These units also compensated, at least partially, for the weakening of frontier defences brought about by the new strategy of Diocletian and especially that of Constantine, which located comitatenses troops in the hinterland. The general view of a late-Roman defensive system consisting simply of limitatenses units stationed in the immediate riparian area with field-army units based at road junctions further behind the frontiers in fact ignores more than a dozen naval units established in the late 3rd and 4th centuries"--Publisher's web site
