Transmountain Diversion In The Forest Wilderness: Natural History Is Human History, José A. Rivera Ph.D

Faculty Publications

The case study details how an adjudication involving the water rights of Indigenous pueblos downstream of rights held by Hispano irrigators led to a prolonged conflict not with the pueblos but between Cuba valley farmers and the United States Forest Service. It happened that an adjudication decree in federal court mandated the Nacimiento Community Ditch Association to replace its diversion located in a wilderness forest with a modern structure to partition water equitably among all users on the Jémez River. The transmountain diversion, as it was called, took water out of the Jémez basin and dropped it to a canyon …

The Zanjeras Of Ilocos In The Northern Philippines: A Legacy Of Sustainable Resource Management, José A. Rivera Ph.D

Faculty Publications

Zanjeras are farmer-managed irrigation systems that have endured for centuries in the Ilocos region of northern Luzon in the Philippines. These cooperative irrigation societies emerged during the Spanish regime when Augustinians were deployed to congregate indigenous populations into pueblos, convert them to Christianity, and raise tributes for the Crown. Zanjeras evolved from a blending of two traditions: the Iberian model of irrigation and indigenized practices of water-for-land exchanges with landowners and atar-holdings to distribute shares among the members. Like other community-based irrigation systems in Southeast Asia and globally, zanjeras are self-governed, long-enduring, and serve as exemplary models of …

Towards A New Paradigm In The Lebanese Urban Management System For Enhanced Master Plans’ Generation, Ali Srour, Baher I. Farahat

Architecture and Planning Journal (APJ)

With the fact that 88% of the population living in urban areas, Lebanon is a highly urbanized country. However, this high urbanization undergoes the severe lack of the proper urban planning methodologies and approaches resulting in the sprawl along infrastructure paths. The weakness or even the complete absence of the plans escorting the urban growth made every city or town a single urban area confronted by plenty of challenges. Decentralization has been a recurrent theme in Lebanese politics for many years, yet it’s now limited by an administrative scale, and at the municipal level only. This administrative decentralization affects the …
