Geolocation of unpublished archaeological sites in the Peruvian Amazon

Published maps identifying archaeological sites in the Amazon basin show a paucity of sites in western Amazonia compared to the Brazilian Amazon. Whereas fewer than two dozen are identified for the Peruvian Amazon on basin-wide maps, a thorough review of unpublished archival material held by the Ministry of Culture of Peru and other sources revealed more than 400 known but unpublished sites in the Department of Loreto, challenging the notion that the region was sparsely occupied in prehistory. Our database provides the geolocation of each site and corresponding references for use by scientists seeking to better understand regional Pre-Columbian human occupation and settlement, cultural change, resource use and their landscape legacies. These data are foundational not only to the development of a richer understanding of prehistory and historical ecology of the Amazon basin but importantly for informing current land use, forest conservation and development policies as well as initiatives to support indigenous land and cultural rights in Amazonia.

The Production and Destruction of Forests through the Lens of Landesque Capital Accumulation

We discuss the management of trees and forests through the lens of “landesque capital.” A theoretical point of departure is how landesque capital accumulates through a process that relies on both the ‘work of nature’ and the ‘work of people.’ This approach highlights the importance of undertaking a critical analysis of labor investment and its landscape legacies in relation to ecological processes, social dynamics, and political economy. Empirically we draw on the case of smallholder production of coffee and annual crops in southwestern Ethiopia. We show how both the production (generation and maintenance) and destruction of forests in the study area are largely shaped by processes of landesque capital accumulation and discuss the importance of analyzing how people contribute to produce forests to meet production goals in contrast to the ubiquitous notion of humans as a solely destructive force of change in forest ecosystems.

The Landscape Legacies of Sugar and Rum

The environmental legacies of sugarcane cultivation at Betty’s Hope were created over a period of three hundred years and involved massive transformations to the landscape. In this chapter, erosion/productivity simulation is used to generate a baseline model of change over time and then historical records and geoarchaeological analysis of soils are used to evaluate the model. It is concluded that contemporary soil degradation at Betty’s Hope is a mosaic of effects including long-term sugarcane monocropping as well as the recent cessation of agriculture, which caused rapid destabilization of already vulnerable landscapes. Using an historical ecology framework, this research demonstrates the importance of long-term perspectives for understanding soil health.

Human Niche Construction and Population Growth in Pre-Columbian Amazonia

The use of Niche Construction Theory in archaeological research demands that we establish empirically how human-constructed niches acted as legacies that shaped the selection pressures affecting past human populations. One potential approach is to examine whether human demography changed as a result of the continued use of landscapes enduringly transformed by past societies. This paper presents proxies for Amazonian population growth during the late Holocene and discusses their significance within the broader context of landscape legacies resulting from cumulative anthropic environmental alteration during pre-Columbian times.
