Download or read book Drones for Biodiversity Conservation and Ecological Monitoring written by Ricardo Díaz-Delgado and published by MDPI. This book was released on 2019-12-18 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAV) have already become an affordable and cost-efficient tool to quickly map a targeted area for many emerging applications in the arena of ecological monitoring and biodiversity conservation. Managers, owners, companies, and scientists are using professional drones equipped with high-resolution visible, multispectral, or thermal cameras to assess the state of ecosystems, the effect of disturbances, or the dynamics and changes within biological communities inter alia. We are now at a tipping point on the use of drones for these type of applications over natural areas. UAV missions are increasing but most of them are testing applicability. It is time now to move to frequent revisiting missions, aiding in the retrieval of important biophysical parameters in ecosystems or mapping species distributions. This Special Issue shows UAV applications contributing to a better understanding of biodiversity and ecosystem status, threats, changes, and trends. It documents the enhancement of knowledge in ecological integrity parameters mapping, long-term ecological monitoring based on drones, mapping of alien species spread and distribution, upscaling ecological variables from drone to satellite images: methods and approaches, rapid risk and disturbance assessment using drones, mapping albedo with UAVs, wildlife tracking, bird colony and chimpanzee nest mapping, habitat mapping and monitoring, and a review on drones for conservation in protected areas.

Download or read book Agroecology Now written by Colin Ray Anderson and published by Springer Nature. This book was released on 2020-12-07 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book develops a framework for advancing agroecology transformations focusing on power, politics and governance. It explores the potential of agroecology as a sustainable and socially just alternative to today’s dominant food regime. Agroecology is an ecological approach to farming that addresses climate change and biodiversity loss while contributing to the Sustainable Development Goals. Agroecology transformations represent a challenge to the power of corporations in controlling food system and a rejection of the industrial food systems that are at the root of many social and ecological ills. In this book the authors analyse the conditions that enable and disable agroecology’s potential and present six ‘domains of transformation’ where it comes into conflict with the dominant food system. They argue that food sovereignty, community-self organization and a shift to bottom-up governance are critical for the transformation to a socially just and ecologically viable food system. This book will be a valuable resource to researchers, students, policy makers and professionals across multidisciplinary areas including in the fields of food politics, international development, sustainability and resilience.

Download or read book A review of evidence on gender equality women s empowerment and food systems written by Njuki, Jemimah and published by Intl Food Policy Res Inst. This book was released on 2021-07-14 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achieving gender equality and women’s empowerment in food systems can result in greater food security and better nutrition, and in more just, resilient, and sustainable food systems for all. This paper uses a scoping review to assess the current evidence on pathways between gender equality, women’s empowerment, and food systems. The paper uses an adaptation of the food systems framework to organize the evidence and identify where evidence is strong, and where gaps remain. Results show strong evidence on women’s differing access to resources, shaped and reinforced by contextual social gender norms, and on links between women’s empowerment and maternal education and important outcomes, such as nutrition and dietary diversity. However, evidence is limited on issues such as gender considerations in food systems for women in urban areas and in aquaculture value chains, best practices and effective pathways for engaging men in the process of women’s empowerment in food systems, and for addressing issues related to migration, crises, and indigenous food systems. And while there are gender informed evaluation studies that examine the effectiveness of gender- and nutrition- sensitive agricultural programs, evidence to indicate the long-term sustainability of such impacts remains limited. The paper recommends keys areas for investment: improving women’s leadership and decision-making in food systems, promoting equal and positive gender norms, improving access to resources, and building cross-contextual research evidence on gender and food systems.

Download or read book The Native Population of the Americas in 1492 written by William M. Denevan and published by Univ of Wisconsin Press. This book was released on 1992-03-15 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: William M. Denevan writes that, "The discovery of America was followed by possibly the greatest demographic disaster in the history of the world." Research by some scholars provides population estimates of the pre-contact Americas to be as high as 112 million in 1492, while others estimate the population to have been as low as eight million. In any case, the native population declined to less than six million by 1650. In this collection of essays, historians, anthropologists, and geographers discuss the discrepancies in the population estimates and the evidence for the post-European decline. Woodrow Borah, Angel Rosenblat, William T. Sanders, and others touch on such topics as the Indian slave trade, diseases, military action, and the disruption of the social systems of the native peoples. Offering varying points of view, the contributors critically analyze major hemispheric and regional data and estimates for pre- and post-European contact. This revised edition features a new introduction by Denevan reviewing recent literature and providing a new hemispheric estimate of 54 million, a foreword by W. George Lovell of Queen's University, and a comprehensive updating of the already extensive bibliography. Research in this subject is accelerating, with contributions from many disciplines. The discussions and essays presented here can serve both as an overview of past estimates, conflicts, and methods and as indicators of new approaches and perspectives to this timely subject.

Download or read book Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment written by Parvaiz Ahmad and published by Springer Science & Business Media. This book was released on 2013-12-02 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stress has a detrimental impact on the living organisms in a specific environment and constitutes a major constraint to global agricultural production. The adverse environmental conditions that plants encounter during their life cycle not only disturb their metabolic reactions, but also hamper their growth and development on cellular and whole plant levels. These conditions are of great concern, particularly for those countries whose economies primarily rely on agriculture. Under abiotic stresses, plants amalgamate multiple external stress cues to bring about a coordinated response and establish mechanisms to mitigate such stresses by triggering a cascade of events leading to enhanced tolerance. Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 displays the ways by which plants utilize and integrate many common signals and subsequent pathways to cope with less favourable environmental conditions. The book also describes the use of contemporary tools for the improvement of plants under such stressed environments. Concise yet comprehensive, Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 is an indispensable resource for researchers, students, environmentalists and many others in this burgeoning area of research.

Download or read book Indigenous South Americans Of The Past And Present written by David J. Wilson and published by Routledge. This book was released on 2018-02-07 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilizing ethnographic and archaeological data and an updated paradigm derived from the best features of cultural ecology and ecological anthropology, this extensively illustrated book addresses over fifteen South American adaptive systems representing a broad cross section of band, village, chiefdom, and state societies throughout the continent over the past 13,000 years.Indigenous South Americans of the Past and Present presents data on both prehistoric and recent indigenous groups across the entire continent within an explicit theoretical framework. Introductory chapters provide a brief overview of the variability that has characterized these groups over the long period of indigenous adaptation to the continent and examine the historical background of the ecological and cultural evolutionary paradigm. The book then presents a detailed overview of the principal environmental contexts within which indigenous adaptive systems have survived and evolved over thousands of years. It discusses the relationship between environmental types and subsistence productivity, on the one hand, and between these two variables and sociopolitical complexity, on the other. Subsequent chapters proceed in sequential order that is at once evolutionary (from the least to the most complex groups) and geographical (from the least to the most productive environments)?around the continent in counterclockwise fashion from the hunter-gatherers of Tierra del Fuego in the far south; to the villagers of the Amazonian lowlands; to the chiefdoms of the Amazon v¿ea and the far northern Andes; and, finally, to the chiefdoms and states of the Peruvian Andes. Along the way, detailed presentations and critiques are made of a number of theories based on the South American data that have worldwide implications for our understanding of prehistoric and recent adaptive systems.
