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.
This book represents the first harvest in the English language of the work of the Land Research Action Network (LRAN). LRAN is an international working group of researchers, analysts, nongovernment organizations, and representatives of social movements. -- pref.
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.
This book examines the key aspects that will define future sustainable energy systems: energy supply, energy storage, security and limited environmental impacts. It clearly explains the need for an integrated engineering approach to sustainable energies, based on mathematical, biogeophysical, and engineering arguments. Resilient and efficient alternatives are compared to non-sustainable options. This book results from the collaboration of 50 international contributors.
