The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.

This study examines the socioeconomic and environmental implications of the new camu camu industry in Peru. Camu camu (Myrciaria dubia) is a small tree native to wetlands of the Amazon basin. It is especially abundant in Peruvian Amazonia. The high vitamin-C content of the fruit has generated interest in exporting camu camu products from Amazonia to more-developed countries. The government of Peru has been actively promoting this new extractive industry, as well as the planting of camu camu in rural areas. Non-governmental development organizations and private industry are now actively involved with camu camu projects and enterprises. In Peru, enthusiasm for this native species is high, because camu camu is expected to provide a much-needed and sustainable economic boost for the region. However, many questions about the environmental implications and socioeconomic impacts of the camu camu export industry need to be answered in order to understand its ecological and economic viability, and its effects on business and in rural communities. Winner of 2010 "Dissertation Excellence Award" Findings indicate that camu camu has provided significantly more income to rural residents than is provided by the traditional boom and bust economies of Amazonia. Households who adopted camu camu as a new crop in their floodplain agroforestry systems farmed significantly more floodplain land than non-adopters, and were especially adept at experimenting with new innovations. Lack of agricultural credit is a major constraint to adopting camu camu as a new crop in Peru. Geographic isolation and the location of processing facilities in relation to fruit harvests present major obstacles to the economic viability of the new industry. Camu camu was found to be cultivated with a higher diversity of annual crops than is typical in floodplain fields of the region. Extraction of camu camu fruits from the wild does not appear to have a negative environmental impact, at least in the initial years of the industry. This non-timber forest product in the process of domestication can support a viable industry in the Peruvian Amazon, if agricultural extension methods and marketing channels are improved.

This report, prepared by the Commission on Development and Environment for Amazonia at the initiative of the Amazon Cooperation Treaty and supported by the Inter-American Development Bank and the United Nations Development Programme, is based on the concept of an Amazonia that exists above and beyond the world of fantasy and myth: an Amazonia of flesh and blood, of human toil, of human history, of human faces and hopes, and future human beings. It is an analysis based not only on the experiences and technologies of today"s world but also, and with greater emphasis, on the wisdom accumulated for centuries by Amazonia itself: standing Amazonia. The Amazon region has the largest area of tropical forest on the planet, and concern for its environmental deterioration extends well beyond the borders of the eight countries that form a part of it. With support from the IDB and UNDP, the Commission on Development and Environment for Amazonia prepared this report that provides data on the region's natural resources, population, health and infrastructure.
