Landslides and slope failure are common in the US and rest of the world. The landslides cause significant damage to infrastructure and millions of dollars are required each year to fix the slope. A sustainable and costeffective option to stabilise the slope can have significant benefits, as it will reduce the cost of maintenance and when using recycled pins, it may help the environment at the same time. The recycled plastic pin is made from recycled plastic bottles and other plastic waste. Several demonstration projects already proved the effectiveness of RPP as an alternative option to fix slope failure, with a maximum failure depth of 7-8 ft. In this book, every detail of the slope stabilisation technique using recycled plastic pins, including the design techniques and several case studies, are included. This will help to explain the basics of this important technique and will be used as reference to design the slope stabilisation scheme using recycled plastic pins.

The textbook Climate Change and Agricultural Food Production: Impacts, Vulnerabilities and Remedies provides an extensive overview of the effects of climate change on all sectors of agricultural food production, including agriculture, livestock, and fisheries.

The book presents information from research results and data from around the world, including Africa, Asia, Australia, Europe, Latin America, North America, the Polar Regions, and Small Island Nations. It has been designed as a textbook, reference book, and extension book, and is written in simple and plain English, with key facts, acronyms, and a glossary provided in each chapter, along with tables and figures to benefit a wide range of readers.

The book is an attempt to address the important facts and figures relating to climate change impacts on water security: a. Climate change impacts on water resources; b. Climate change impacts on water related diseases; c. Climate change impacts on water dependent biodiversity and ecosystems; d. Climate change adaptation and mitigation measures for water security; and e. Climate change and greenhouse gas emissions from water sector.Climate change is an additional stress on water security in addition to other chemical and biological stressors.Rivers depending on the Himalayan glaciers (the Indus, Ganges, Brahmaputra) could face water shortages or reduced river run-off due to retreat of glaciers, and this would cause dramatic impact on drinking water supplies, biodiversity, hydropower generation, industry, agriculture, ecosystems on which about 2.4 billion people in Asia depends.As a consequence of drought, the annual stream flow in the Murray-Darling basin (Australia) is projected to fall by 10-25% by 2050 and 16-48% by 2100 which would have severe consequences on irrigated agriculture in the region.Rise of water temperatures may enhance proliferation of harmful algae (some of algae produce toxins), causing water quality problems for recreational activities, fisheries/fish farming, irrigation, and drinking and seafood contamination with algal toxins.Global warming is projected to increase river water temperatures in a number of countries including the USA (the Mississippi, Colorado, and Mackenzie basins), Europe (the Rhine, Danube, and Rhone basins), eastern China (the Yangtze), and Australia (the Murray-Darling).Sea-level rise (SLR) will cause salinization of coastal groundwater resources, and may damage or destroy many coastal ecosystems including wetlands, salt marshes, and may cause saline water intrusion in agriculture and freshwater aquaculture facilities, a shift in community composition of mangrove forests, etc.It is projected that a 1°C rise of temperature in the future can increase the initial relative risks of cholera by 15 to 29 percent. Both rise of temperature and sea-level may enhance dengue and malaria.To adapt to climate change, we need increasing storage capacity, rainwater harvesting, improvement of water use efficiency, desalination of seawater, water savings, mandatory rainwater tanks in new and old buildings, use of recycled/reclaimed water, virtual water trade, improvements in irrigation efficiency, modification of irrigation techniques, reducing leakage of irrigation pipes, selection of climate resilient crops to save scarcity of water resources.Water processes (abstraction, treatment, end use and wastewater treatment) do emit Greenhouse gases (GHG). In irrigation, pumping of water is the most energy-demanding process and consequently causes more GHG emissions (CO2). Dams/reservoirs emit GHGs such as methane.The most effective way to decrease carbon footprint in water sectors is to use low carbon emitting fuels such as, renewable energy (solar, wind or nuclear). Ecological toilet may be promoted to reduce GHG emissions from septic tanks in developing countries.Stopping or slowing deforestation, forest degradation and sustainable management of forests may significantly contribute to avoid GHG emissions, may conserve water resources and prevent flooding, reduce run-off, control erosion, reduce siltation of rivers, and protect fisheries and preserve biodiversity.Mangrove ecosystems can play an important role in the protection of the coast from the natural disasters (cyclones, tsunamis) and could act as a barrier (live seawalls) against disasters and help minimize damage to property and life.

This book offers a comprehensive collection of micro electrical discharge machining (EDM) processes, including hybrid processes.

This book bridges the gap between the demand for micro-featured components on the one hand, and successful micromachining of miniature products on the other. In addition to covering micromachining in the broader sense, it specifically addresses novel machining strategies implemented in various advanced micromachining processes to improve machining accuracy, energy consumption, component durability, and miniature-scale applicability. The book’s main goal is to present the capabilities of advanced micromachining processes in terms of miniature product manufacturing by highlighting various innovative machining strategies that can be used to augment the production scale and precision alike.
