This highly topical book provides an in-depth account of the South Asian experience with the deadly disease that has held this region hostage for millennia. The book touches specifically on the resurgence of malaria experienced in the second half of the twentieth century, which occurred just a few years after malaria was thought to have been virtually eradicated from the region. The progress of this reappearance across space and time, as well as its causes and consequences, are discussed. The book also covers past, present and future ways to curb, control and ultimately, conquer malaria. As malaria continues to ravage the developing world, even in today s age of science, this is a particularly relevant book, especially as most studies analyze the problem in Africa, the continent that bears the brunt of this disease. Here, the authors call attention to challenges in South Asia, home to an immense at-risk population. The chapters in this book use a range of conceptual frameworks, quantitative analyses and descriptive aapproaches, finding that malaria is not just a complex disease driven by highly adaptive agents and vectors thriving in particular ecologies, but also a social concern deeply related to the region s cultural traditions, financial and developmental shortfalls, and inexorably related to political will. The book comprehensively deals with all aspects of the malaria situation in South Asia, and is invaluable to upper level students as well as emerging and established scholars in the fields of medical geography and epidemiology, Asian studies and development studies."

This textbook provides students and academics with a conceptual understanding of fire behavior and fire effects on people and ecosystems to support effective integrated fire management. Through case studies, interactive spreadsheets programmed with equations and graphics, and clear explanations, the book provides undergraduate, graduate, and professional readers with a straightforward learning path. The authors draw from years of experience in successfully teaching fundamental concepts and applications, synthesizing cutting-edge science, and applying lessons learned from fire practitioners. We discuss fire as part of environmental and human health. Our process-based, comprehensive, and quantitative approach encompasses combustion and heat transfer, and fire effects on people, plants, soils, and animals in forest, grassland, and woodland ecosystems from around the Earth. Case studies and examples link fundamental concepts to local, landscape, and global fire implications, including social-ecological systems. Globally, fire science and integrated fire management have made major strides in the last few decades. Society faces numerous fire-related challenges, including the increasing occurrence of large fires that threaten people and property, smoke that poses a health hazard, and lengthening fire seasons worldwide. Fires are useful to suppress fires, conserve wildlife and habitat, enhance livestock grazing, manage fuels, and in ecological restoration. Understanding fire science is critical to forecasting the implication of global change for fires and their effects. Increasing the positive effects of fire (fuels reduction, enhanced habitat for many plants and animals, ecosystem services increased) while reducing the negative impacts of fires (loss of human lives, smoke and carbon emissions that threaten health, etc.) is part of making fires good servants rather than bad masters.

In the last decades the public concern on the pesticide residues content in foods have been steadily rising. The global development of food trade implies that aliments from everywhere in the world can reach the consumer`s table. Therefore, the identification of agricultural practices that employ different pesticides combinations and application rates to protect produce must be characterized, as they left residues that could be noxious to human health. However, the possible number of pesticides (and its metabolites of toxicological relevance) to be found in a specific commodity is almost 1500, and the time needed to analyze them one by one, makes this analytical strategy a unrealistic task. To overcome this problem, the concept of Multi Residue Methods (MRM) for the analysis of pesticide traces have been developed. The advent of new and highly sensitive instrumentation, based in hyphenatedchromatographic systems to coupled mass analyzers (XC (MS/MS) or MSn) permitted simultaneously the identification and the determination of up to hundreds of pesticide residues in a single chromatographic run. Multiresidue Methods for the Analysis of Pesticide Residues in Food presents the analytical procedures developed in the literature, as well as those currently employed in the most advanced laboratories that perform routinely Pesticide Residue Analysis in foods. In addition to these points, the regulations, guidelines and recommendations from the most important regulatory agencies of the world on the topic will be commented and contrasted.
