Nothing serves to remind us of the instability of the globalized order as much as the continuing power of territorial boundaries to spawn political and humanitarian crises. Although it might seem that in this important respect the modern world has made little progress, the work of Gerald Blake continues to prove that peaceful resolution of problems associated with international boundaries can be attained. This festschrift reflects the topics and regional preoccupations of one of the leading researchers in the field. Professor Blake returned to certain topics throughout his long career, especially the Middle East, maritime boundaries, and the relation between borders and demographics. Several of the authors extend his work in such areas as Arctic jurisdiction, environmental issues of transboundary water management, and geographic information systems (GIS). For the growing number of professionals in conflict management, international humanitarian law, the law of the sea, environmental law, and energy law, and for workers in such diverse fields as natural resource management and forced migrations - as well as for specialists in the Middle East, Africa, and South East Asia - these revealing essays should offer a wealth of valuable information and insight.
