Historical Ecology and Archaeology in the Galápagos Islands explores human history in the Galápagos Islands, which is today one of the world’s premier nature attractions. From its early beginnings, the Galápagos National Park connected a dual vision of biological conservation with responsible tourism. However, despite its popular perception as a pristine nature park, the archipelago has experienced protracted interactions with humans at least since its accidental discovery in 1535. This book contextualizes six years of interdisciplinary archaeological and historical research on San Cristóbal, the easternmost island in the archipelago. It focuses on the interior highland community of El Progreso and specifically the preserved vestiges of a 19th-century sugar plantation, the Hacienda El Progreso, which left the most intensive historic footprint of human activity in the islands. It did not do this alone, as other islands, particularly those with potable water sources, were varyingly impacted by human encounters. Proceeding within a framework of Historical Ecology, the book integrates archaeological research with historical and ecological study and incorporates three interconnected perspectives: 1. globalization and the increasing integration of the islands into an expanding network of human interests; 2. anthropogenic transformation of distinctive island habitats into novel or emerging ecosystems; and, 3. changing popular and scientific perceptions of nature and ecotourism’s role in biological conservation, preservation, and restoration.

AbstractThe unique marine and terrestrial ecosystems of the Galapagos Islands are highly vulnerable to human-based drivers of change, including the introduction of invasive species, unsustainable tourism, illegal fishing, overexploitation of ecosystem services, and climate change. These drivers can interact with climate-based drivers such as El Niño-Southern Oscillation (ENSO) at multiple temporal and spatial scales, exacerbating their negative impacts on already fragile ecosystems and the socioeconomic system of the Archipelago. In this review, we performed a literature review based on published literature from 1945 to 2020 and local and global climate databases to analyze drivers of change in the Galapagos. We developed and applied a spatial impact assessment model to identify high-ecological value areas with high sensitivity and exposure scores to environmental change drivers. We identified 13 priority HEVA that encompass ca. 23% (14,715 km2) of the Galapagos Archipelago, distributed in nearly 3% of the Galapagos Marine Reserve and 20% Galapagos National Park. Current and future impacts are likely to concentrate on the inhabited islands’ highlands, whereas marine impacts concentrate along most of the Galapagos Islands’ shorelines. These results are important for guiding the design and implementation of adaptation measures aimed at increasing ecosystem resilience and human adaptive capacity in the face of global environmental change. Overall, these results will be valuable in their application for preserving Galapagos biota, securing the provision of vital ecosystem services for resident human populations, and sustaining the nature-based tourism industry.
