Book excerpt: Objetivando avaliar cultivares de bananeira em Guama-PA, foram introduzidos nove acessos entre cultivares e hibridos resistentes as principais pragas e doencas da planta. Dos acessos testados (JV 03-15, Mysore, Nam, PA03-22, PA 12-03, PV 03-44, PV 03-76, Thap-maeo, Yangambi), foram plantadas 36 mudas, por acesso, em fileiras duplas, em espacamentos de 5m x 3m x 3m, com delineamento experimental inteiramente casualizado. Em cada touceira foram deixadas tres plantas (mae, filha, neta). Caracteristicas observadas: altura da planta, medida do nivel do solo ate a intersecao do cacho, por ocasiao da floracao; circunferencia do pseudo caule, a 30cm do solo, tambem por ocasiao da floracao; data da colheita do cacho; frutos por penca; e numero de frutos por cacho. Todos os acessos aumentaram em altura e circunferencia do pseudocaule do primero para o segundo ciclo de producao. Nam foi a cultivar com menor aumento (0,15m) para altura; e o hibrido PV 03-76, o de maior aumento (0,72m). O hibrido PA 12-03 apresentou os cachos mais pesados (11,57kg/cacho e 12,63kg/cacho no primeiro e segundo ciclo, respectivamente), sendo, tambem, o mais precoce em floracao e producao, com intervalo (em dias), entre a emergencia da inflorescencia e a colheita, de 134,6 e126,7 dias, para o primeiro e segundo ciclos de producao. A cultivar Thap-maeo apresentou intervalos de floracao a colheita mais tardios, porem com menor invervalo (em dias), entre a emergencia da inflorescencia e a colheita, menos de 90 dias, nos dois ciclos de producao. Foi observada a ocorrencia do mal de sigatoka nas cultivares Mysore, Thap-maeo e PA 12-03. Considerando as avaliacoes efetuadas, nos dois primeiros ciclos de producao, destacaram-se PA 1203, PA 03-22, Yangambi km5 e JV 03-15.

Available in PDF, EPUB and Kindle. Book excerpt: Today, globalisation and homogenisation have replaced local food cultures. The 12 case studies presented in this book show the wealth of knowledge in indigenous communities in diverse ecosystems, the richness of their food resources, the inherent strengths of the local traditional food systems, how people think about and use these foods, the influx of industrial and purchased food, and the circumstances of the nutrition transition in indigenous communities. The unique styles of conceptualising food systems and writing about them were preserved. Photographs and tables accompany each chapter.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with useful plants of neotropical origin, i.e., plants which have been cultivated in Southern and Central America as well as their wild relatives. Quite a number of these trees and bushes have "conquerred" the world as early as 400 years ago and are nowadays of utmost importance for feeding the increasing world population (e.g., potatoes). It has been estimated that about 150 such useful plants stem from the "New World." This book does not only describe the current theories about their domestication, cultivation, and evolution; it also discusses biotechnological methods for improving their productivity. About the German edition: ..". One of the most interesting and recurring themes of this book concerns some little-known species of potential value which may well become important to a future which is certain to present us with serious problems, at least as far as alimentation is considered. BrA1/4cher's book is absolutely up to date in the taxonomic and nomenclatural sense..." "Excerpta Botanica"#1

Available in PDF, EPUB and Kindle. Book excerpt: A significant work of neotropical archaeology presenting evidence of early hunter-gatherers who produced fiber-tempered ceramics. Few topics in the development of humans have prompted as much interest and debate as those of the origins of pottery and agriculture. The first appearance of pottery in any area of the world is heralded as a new stage in the progress of humans toward a more complex arrangement of thought and society. Cultures are defined and separated by the occurrence of pottery types, and the association of pottery with mobility and agriculture continues to drive research in anthropology. For these reasons, the discovery of the earliest fiber-tempered pottery in the New World and carbonized remains identified as maize kernels is exciting. San Jacinto 1 is the archaeological site located in the savanna region of the north coast of Colombia, South America, where excavations by led by the authors have revealed evidence of mobile hunter-gatherers who made pottery and who collected and processed plants from 6000 to 5000 B.P. The site is believed to show an early human adaptation to the tropics in the context of significant environmental changes that were taking place at the time. This volume presents the data gathered and the interpretations made during excavation and analysis of the San Jacinto 1 site. By examining the social activities of a human population in a highly seasonal environment, it adds greatly to our contemporary understanding of the historical ecology of the tropics. Study of the artifacts excavated at the site allows a window into the early processes of food production in the New World. Finally, the data reveals that the origins of ceramic technology in the tropics were tied to a reduction in mobility and an increase in territoriality and are widely applicable to similar studies of sedentism and agriculture worldwide.

This book was released on 2013-03-22 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry -- the practice of integrating trees and other large woody perennials on farms and throughout the agricultural landscape -- is increasingly recognized as a useful and promising strategy that diversifies production for greater social, economic, and environmental benefits. Agroforestry and BiodiversityConservation in Tropical Landscapes brings together 46 scientists and practitioners from 13 countries with decades of field experience in tropical regions to explore how agroforestry practices can help promote biodiversity conservation in human-dominated landscapes, to synthesize the current state of knowledge in the field, and to identify areas where further research is needed. Agroforestry and Biodiversity Conservation in Tropical Landscapes is the first comprehensive synthesis of the role of agroforestry systems in conserving biodiversity in tropical landscapes, and contains in-depth review chapters of most agroforestry systems, with examples from many different countries. It is a valuable source of information for scientists, researchers, professors, and students in the fields of conservation biology, resource management, tropical ecology, rural development, agroforestry, and agroecology.

Available in PDF, EPUB and Kindle. Book excerpt: There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.

Book excerpt: Moundbuilders of the Amazon shows that sophisticated archaeological, bioarchaeological, and geophysical techniques of remote sensing are fully applicable to tropical sites. Additionally, the comprehensive use of such techniques by all archaeologists, doing fieldwork anywhere, could revolutionize archaeology, allowing archaeologists to look inside sites rather than simply excavate them.**Using a variety of remote sensing techniques, Roosevelt documents the existence of a major moundbuilding culture possessing monumental architecture and a rich artistic tradition on the lowland tropical floodplain of Marajo Island at the mouth of the Amazon River in Brazil, from about 400 A. D. to about 1,300 A. D.**Marajo Island at the mouth of the Amazon River is about the same size as Switzerland or Belgum. A well developed civilization existed there from about 400 A. D. to 1,300 A. D., comparable in many ways to the Inca civilization to the west or to the Aztec and Maya cultures to the north or, in some interesting ways, to the Pharonic cultures which developed at the mouth of the Nile. Because this civilization had no stone at its disposal, it expressed its monumental architecture in packed dirt which washed back into the alluvial floodplain long ago, effectively preventing archaeological discovery until the recent development of sophisticated techniques of remote sensing and reconstruction. Key Features * Reports on the most extensive stratigraphic excavations ever of an ancient Amazonian civilization adapted to a floodplain environment * Introduces the first use of geophysics for archaeology in non-specialized language * Illustrates, for the first time, the elaborate art of a complex society that was indigenous to the tropical lowlands * Describes monumental sites, rich polychrome pottery, and the first extensive biological remains ever recovered in an Amazonian site * Proves that sophisticated archaeological, bioarchaeological, and geophysical techniques of remote sensing are fully applicable to tropical sites * Shows that the comprehensive use of such methods could revolutionize archaeology by allowing archaeologists to look inside sites rather than simply excavate them * Provides examples which prove that the theories about the limitations of the tropical environment for cultural evolution are simply untrue and were based on faulty knowledge of the region and its archaeology
