Book Description
This publication provides an overview of the common and unique sustainability elements of Indigenous Peoples' food systems, in terms of natural resource management, access to the market, diet diversity, indigenous peoples’ governance systems, and links to traditional knowledge and indigenous languages. While enhancing the learning on Indigenous Peoples food systems, it will raise awareness on the need to enhance the protection of Indigenous Peoples' food systems as a source of livelihood for the 476 million indigenous inhabitants in the world, while contributing to the Zero Hunger Goal. In addition, the UN Decade of Action on Nutrition (2016-2025) and the UN Food Systems Summit call on the enhancement of sustainable food systems and on the importance of diversifying diets with nutritious foods, while broadening the existing food base and preserving biodiversity. This is a feature characteristic of Indigenous Peoples' food systems since hundreds of years, which can provide answers to the current debate on sustainable food systems and resilience.

Book Description
The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Book Description
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.

Book Description
This publication deals with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural development interventions, with often long-lasting, negative results. This guide is designed to assist technical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination, and conflicts, where land tenure is currently of critical concern.

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 well known text helps students understand the art of model building - what type of model to build, building the appropriate model, testing it statistically, and applying the model to practical problems in forecasting and analysis.
