The sudden appearance of portolan charts, realistic nautical charts of the Mediterranean and Black Sea, at the end of the thirteenth century is one of the most significant occurrences in the history of cartography. Using geodetic and statistical analysis techniques these charts are shown to be mosaics of partial charts that are considerably more accurate than has been assumed. Their accuracy exceeds medieval mapping capabilities. These sub-charts show a remarkably good agreement with the Mercator map projection. It is demonstrated that this map projection can only have been an intentional feature of the charts' construction. Through geodetic analysis the author eliminates the possibility that the charts are original products of a medieval Mediterranean nautical culture, which until now they have been widely believed to be.

This open access book presents a nuanced and accessible synthesis of the relationship between land tenure security and sustainable development. Contributing authors have collectively worked for decades on land tenure as connected with conservation and development across all major regions of the globe. The first section of this volume is intended as a standalone primer on land tenure security and its connections with sustainable development. The book then explores key thematic challenges that interact directly with land tenure security, followed by a section on strategies for addressing tenure insecurity. The book concludes with a section on new frontiers in research, policy, and action. An invaluable reference for researchers in the field and for practitioners looking for a comprehensive overview of this important topic. This is an open access book.
