Book Description
A unique approach to the challenges of complex environmental systems Environmental Transport Processes, Second Edition provides much-needed guidance on mass transfer principles in environmental engineering. It focuses on working with uncontrolled conditions involving biological and physical systems, offering examples from diverse fields, including mass transport, kinetics, wastewater treatment, and unit processes. This new edition is fully revised and updated, incorporating modern approaches and practice problems at the end of chapters, making the Second Edition more concise, accessible, and easy to use. The book discusses the fundamentals of transport processes occurring in natural environments, with special emphasis on working at the biological physical interface. It considers transport and kinetics in terms of systems that involve microorganisms, along with in-depth coverage of particles, size spectra, and calculations for particles that can be considered either spheres or fractals. The book's treatment of particles as fractals is especially unique and the Second Edition includes a new section on exoelectrogenic biofilms. It also addresses dispersion in natural and engineered systems unlike any other book on the subject. Readers will learn to tackle with confidence complex environmental systems and make transport calculations in heterogeneous environments with mixtures of chemicals.

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Description
This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

Book Description
Rural movements have recently emerged to become some of the most important social forces in opposition to neoliberalism. From Brazil and Mexico to Zimbabwe and the Philippines, rural movements of diverse political character, but all sharing the same social basis of dispossessed peasants and unemployed workers, have used land occupations and other tactics to confront the neoliberal state. This volume brings together for the first time across three continents - Africa, Latin America and Asia - an intellectually consistent set of original investigations into this new generation of rural social movements. These country studies seek to identify their social composition, strategies, tactics, and ideologies; to assess their relations with other social actors, including political parties, urban social movements, and international aid agencies and other institutions; and to examine their most common tactic, the land occupation, its origins, pace and patterns, as well as the responses of governments and landowners. At a more fundamental level, this volume explores the ways in which two decades of neoliberal policy - including new land tenure arrangements intended to hasten the commodification of land, and new land uses linked to global markets -- have undermined the social reproduction of the rural labour force and created the conditions for popular resistance. The volume demonstrates the longer-term potential impact of these movements. In economic terms, they raise the possibility of tackling immiseration by means of the redistribution of land and the reorganisation of production on a more efficient and socially responsible basis. And in political terms, breaking the power of landowners and transnational capital with interests in land could ultimately open the way to an alternative pattern of capital accumulation and development.

Book Description
This book provides a comprehensive guide to the large number of diseases, disorders and injuries that can cause severe economic losses to banana, plantain, abaca and enset crops. Most of the diseases are described and illustrated in color, making the book valuable as a diagnostic tool. It also provides information on the fungi, bacteria, viruses, nematodes and abiotic factors involved in the diseases/disorders described. Information is provided on the origin and classification of banana, the safe movement of Musa germplasm and banana breeding, including possibilities for genetic engineering for disease resistance.
