This book could serve as an excellent source for the readers to understand the history and development of the HoB Initiative. It can be used for policymakers, scientists and researchers, as well as the relevant stakeholders in the trans-border area Kalimantan. As the initiator of the HOB, Indonesia also leads and maintain the initiative for enhancing policy and technical cooperation to sustainably manage and conserve the trans-border area for better future of Kalimantan – and Borneo in general – and its people who live there and associated with the unique ecosystem and culture.

This book starts with depicting the history of connectivity in Borneo which leads to the development of HoB (Chapter 2) and follows by the delineation of HoB in Indonesia territory and its status of land (Chapter 3). It continues with the illustration of the Bornean richness of biodiversity, ecosystem and complex social-economy within the area (Chapter 4 and 5). The book then describes the green initiative within the HoB launched by the Indonesia government that could be implemented in the near future (Chapter 6) and the vast natural resources in the area (Chapter 7).

In running the initiative, the government of Indonesia has been working hand-in-hand with civil societies and donor countries to finance the HoB programs (Chapter 8), which include developing green economic corridor (Chapter 9). The remaining part of the book portraits the current threat to the HoB area (Chapter 10), the government effort to manage the area by establishing the spatial plan and HoB Strategic Area (Chapter 11). The book ends with the outlook of the future (Chapter 12).
