Contemporary scholars seeking to increase Tuber Melanosporum truffle production rely almost exclusively on technological advancements to increase yields, while failing to place the cultivation of truffles, trufficulture, in its historical or local landscape contexts. In this dissertation, I describe how truffle scholars’ conceptualization of trufficulture and landscapes has changed over 150 years in France, while focusing on the French département of Lot. I examine changing relations between humans and nonhumans and how they impact truffle harvests. I analyzed the history of French trufficulture through a close reading of historic truffle manuals, archival research and the classification of remotely sensed images. Shifting from the past to the present, from July 2014-August 2016, I conducted semi-structured survey interviews with working truffle-growers (trufficulteurs) and participant observation at meetings of trufficulteurs, truffle hunts and truffle markets. I utilize actor-network theory (ANT) as both a theory and methodology. Actor-network theory allowed me to follow the impacts made by both humans and nonhumans on trufficulture. I found that truffle harvests in the 1880s dropped by 90%. Highly populated, intensively worked landscapes of viticulture, silvopastoralism and cereal cultivation created conditions suitable to truffles. By the 1870s the phylloxera aphid ravaged grapevines, which made trufficulture an important source of revenue. These advantageous conditions would not last. Post-WWI, yields fell for decades because of an ongoing rural population exodus and consequent agricultural abandonment, which promoted reforestation and closed canopy forests in Lot, France. By the 1960s, French trufficulteurs organized associations to share knowledge and promote local truffle markets to revive production. Trufficulteurs’ utilization of tractors, ‘inoculated’ plants and irrigation systems produced a new form of “modern” trufficulture. State subsidies helped trufficulteurs adopt “modern” practices, in hopes of increasing yields. “Modern” trufficulture has not dramatically increased yields. A few highly-capitalized trufficulteurs dominate production in Lot. Many others practice trufficulture as a hobby. Instead of relying on “modern” technological fixes, my findings suggest that trufficulteurs, farmers and states should reinvigorate extensive polyculture farming practices that maintain open canopy forests, which were beneficial to trufficulture in the past. Actor-network theory allowed me to rethink human and nonhuman relations, and to propose alternatives to “modern” trufficulture.

This thesis explores the contributive role of architecture to the prosperity of a place. The research addresses the challenges and opportunities that rural regions face today by analyzing the general factors of marginalized rural communities through the lens of a specific community in mainland Portugal. A new approach for maintaining an authentic character, and a “sense of place” is presented which defends rural space as a genuinely experiential realm. The thesis proposes the design of a modern day treatment and research centre in the rural town of Manteigas, situated on one of the largest glacier valleys in Europe in the heart of the Serra da Estrela mountain range. Once alive with all the quaint characteristics that typify an idyllic rural identity, this town now faces a steep population decrease. Situated in the centre of the Zêzere glacial valley overlooking the town, the design accepts and interprets the natural geology of the site, harnessing the therapeutic thermal waters that continue to flow from the glacier line of the valley. The new centre represents not just a place for leisure and relaxation, but also an investigative laboratory for modern day natural healing therapies. The town of Manteigas is situated within three very distinct landscapes: a fertile landscape, a socio-cultural landscape, and a landscape of health and wellness. The design intervention responds to all these conditions and is dependent on each in its operation. This thesis is a proposal for a sustainable cycle of local and regional rejuvenation that will not be easily broken. The design proposal aims to build an infrastructure that will revive the identity of the community as a place of study and implementation of natural healing. The proposed design will also act as a catalyst to fuel future development and stimulate the local and regional economies.
