An ethnographic portrayal of the lives of white citizens of the Okavango Delta, Botswana, this book examines their relationships with the natural and social environments of the region. In response to the insecurity of their position as a European-descended minority in a postcolonial African state, Gressier argues that white Batswana have developed cultural values and practices that have allowed them to attain high levels of belonging. Adventure is common for this frontier community, and the book follows their safari lifestyles as they construct and perform localized identities in their interactions with dangerous wildlife, the broader African community, and the global elite via their work in the nature-tourism industry.

Amazonian indigenous peoples have preserved many aspects of their culture and cosmology while also developing complex relationships with dominant non-indigenous society. Until now, anthropological writing on Amazonian peoples has been divided between \"traditional\" topics like kinship, cosmology, ritual, and myth, on the one hand, and the analysis of their struggles with the nation-state on the other. What has been lacking is work that bridges these two approaches and takes into consideration the meaning of relationships with the state from an indigenous perspective.That long-standing dichotomy is challenged in this new ethnography by anthropologist José Kelly. Kelly places the study of culture and cosmology squarely within the context of the modern nation-state and its institutions. He explores Indian-white relations as seen through the operation of a state-run health system among the indigenous Yanomami of southern Venezuela.With theoretical foundations in the fields of medical and Amazonian anthropology, Kelly sheds light on how Amerindian cosmology shapes concepts of the state at the community level. The result is a symmetrical anthropology that treats white and Amerindian perceptions of each other within a single theoretical framework, thus expanding our understanding of each group and its influences on the other. This book will be valuable to those studying Amazonian peoples, medical anthropology, development studies, and Latin America. Its new takes on theory and methodology make it ideal for classroom use.

In Gilded Voices: Economics, Politics, and Storytelling in the Yangzi Delta since 1949, Qiliang He pieces together published, archival, and oral history sources to explore the role of the cultural market in mediating between the state and artists in the PRC era. By focusing on pingtan, a storytelling art using the Suzhou dialect, the book documents both the state's efforts to police artists and their repertoire and storytellers' collaboration with, as well as resistance to, state supervision and intervention. The book thereby challenges long-held scholarly assumptions about the Chinese Communist Party's success in politicizing popular culture, patronizing artists, abolishing the cultural market, and enforcing rigid censorship in Mao's times.

The monitoring and assessment of land use/land cover (LULC) change over large areas are significantly important in numerous research areas, such as natural resource protection, sustainable development, and climate change. However, accurately extracting LULC only using the spectral features of satellite images is difficult owing to landscape heterogeneities over large areas. To improve the accuracy of LULC classification, numerous studies have introduced other auxiliary features to the classification model. The Google Earth Engine (GEE) not only provides powerful computing capabilities, but also provides a large amount of remote sensing data and various auxiliary datasets. However, the different effects of various auxiliary datasets in the GEE on the improvement of the LULC classification accuracy need to be elucidated along with methods that can optimize combinations of auxiliary datasets for pixel- and object-based classification. Herein, we comprehensively analyze the performance of different auxiliary features in improving the accuracy of pixel- and object-based LULC classification models with medium resolution. We select the Yangtze River Delta in China as the study area and Landsat-8 OLI data as the main dataset. Six types of features, including spectral features, remote sensing multi-indices, topographic features, soil features, distance to the water source, and phenological features, are derived from auxiliary open-source datasets in GEE. We then examine the effect of auxiliary datasets on the improvement of the accuracy of seven pixels-based and seven object-based random forest classification models. The results show that regardless of the types of auxiliary features, the overall accuracy of the classification can be improved. The results further show that the object-based classification achieves higher overall accuracy compared to that obtained by the pixel-based classification. The best overall accuracy from the pixel-based (object-based) classification model is 94.20% (96.01%). The topographic features play the most important role in improving the overall accuracy of classification in the pixel- and object-based models comprising all features. Although a higher accuracy is achieved when the object-based method is used with only spectral data, small objects on the ground cannot be monitored. However, combined with many types of auxiliary features, the object-based method can identify small objects while also achieving greater accuracy. Thus, when applying object-based classification models to mid-resolution remote sensing images, different types of auxiliary features are required. Our research results improve the accuracy of LULC classification in the Yangtze River Delta and further provide a benchmark for other regions with large landscape heterogeneity.

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. Written by a team of independent water experts, this analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the authors find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal-conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy to maintain both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This important assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.

The flood is a well-known phenomenon in the Vietnamese Mekong River Delta (MRD). Although people have experienced the impact of floods for years, some adapt well, but others are vulnerable to floods. Resilience to floods is a useful concept to study the capacity of rural households to cope with, adapt to, and benefit from floods. Knowledge of the resilience of households to floods can help disaster risk managers to design policies for living with floods. Most researchers attempt to define the concept of resilience; very little research operationalizes it in the real context of “living with floods”. We employ a subjective well-being approach to measure households’ resilience to floods. Items that related to households' capacity to cope with, adapt to, and benefit from floods were developed using both a five-point Likert scale and dichotomous responses. A factor analysis using a standardized form of data was employed to identify underlying factors that explain different properties of households’ resilience to floods. Three properties of households’ resilience to floods were found: (1) households' confidence in securing food, income, health, and evacuation during floods and recovery after floods; (2) households' confidence in securing their homes not being affected by a large flood event such as the 2000 flood; (3) households' interests in learning and practicing new flood-based farming practices that are fully adapted to floods for improving household income during the flood season. The findings assist in designing adaptive measures to cope with future flooding in the MRD.

Large-river delta-front estuaries (LDE) are important interfaces between continents and the oceans for material fluxes that have a global impact on marine biogeochemistry. In this article, we propose that more emphasis should be placed on LDE in future global climate change research. We will use some of the most anthropogenically altered LDE systems in the world, the Mississippi/Atchafalaya River and the Chinese rivers that enter the Yellow Sea (e. g., Huanghe and Changjiang) as case-studies, to posit that these systems are both \"drivers\" and \"recorders\" of natural and anthropogenic environmental change. Specifically, the processes in the LDE can influence (\"drive\") the flux of particulate and dissolved materials from the continents to the global ocean that can have profound impact on issues such as coastal eutrophication and the development of hypoxic zones. LDE also record in their rapidly accumulating subaerial and subaqueous deltaic sediment deposits environmental changes such as continental-scale trends in climate and land-use in watersheds, frequency and magnitude of cyclonic storms, and sea-level change. The processes that control the transport and transformation of carbon in the active LDE and in the deltaic sediment deposit are also essential to our understanding of carbon sequestration and exchange with the world ocean—an important objective in global change research. U. S. efforts in global change science including the vital role of deltaic systems are emphasized in the North American Carbon Plan (www.carboncyclescience.gov).

This book is one of the first ethnographies written on the life of farmers in rural Southern Vietnam since the economic reform in the 1980s. It investigates how social, economic and political factors affect the farmers' life in the Mekong Delta in the late socialist era with a particularly focus on the family, which serves as the basic and most significant social unit for the farmers. Dealing with classical anthropological topics of kinship and family, the book examines them as dynamic institutions. With vivid illustrations of the village life, family farming, education of children, jobs outside of farming and everyday politics, it presents new and different pictures of the current Vietnamese family under rapid social changes. The book will contribute to the current ethnographical research in Vietnam and Southeast Asia and also be of particular interest to those working on society and culture in the geographical region from broader disciplines. It will also appeal to readers who are interested in such topics as late socialism, social transformation, and rural development.

In the current research, water quality of Meriç River Delta was evaluated using some toxic element risk assessment indices. Samples were collected from 24 locations and nickel (Ni), chromium (Cr), arsenic (As), zinc (Zn), lead (Pb), copper (Cu) and cadmium (Cd) accumulations in delta components were read using an ICP-MS. Water quality index (WQI), heavy metal pollution index (HPI), heavy metal evaluation index (HEI) and degree of contamination index (Cdeg) were applied to detected data for assessing the water quality. Also, the toxic element concentrations in water were assessed in terms of public health using some health risk assessment methods including hazard index (HI), hazard quotient (HQ) and cancer risk (CR). According to the results of WQI, HPI, HEI and Cdeg, Ni and As were recorded as most dangerous toxicants among the investigated elements and Gala Lake was recorded as most effected delta component. According to the results HQs and CR, As was recorded as the most dangerous toxicant among the investigated elements and Gala Lake and Ergene River were recorded as the most effected delta components.
