Hosseini, Mohammadreza \ 2018
Methodology for estimating emissions from agriculture in the Netherlands – update 2018 : calculations of CH4, NH3, N2O, NOx, PM10, PM2.5 and CO2 with the National Emission Model for Agriculture (NEMA) [Monograph]
Vonk, J. \ Sluis, S.M. van der \ Bannink, A. \ Bruggen, C. van \ Groenestein, C.M. \ Huijsmans, J.F.M. \ Kolk, J.W.H. van der \ Lagerwerf, L.A. \ Luesink, H.H. \ Oude Voshaar, S.V. \ Velthof, G.L. \ 2018

The National Emission Model for Agriculture (NEMA) is used to calculate emissions to air from agricultural activities in the Netherlands on a national scale. Emissions of ammonia (NH3) and other N-compounds (NOx and N2O) are calculated from animal housing, manure storage, manure application and grazing using a Total Ammoniacal Nitrogen (TAN) flow model. Furthermore, emissions from application of inorganic N fertilizer, compost and sewage sludge, cultivation of organic soils, crop residues, and ripening of crops are calculated. NEMA is also used to estimate emissions of methane (CH4) from enteric fermentation and manure management, particulate matter (PM) from manure management and agricultural soils and carbon dioxide (CO2) from liming. Emissions are calculated in accordance with international guidance criteria and reported in an annual Informative Inventory Report (IIR; for air pollutants) and National Inventory Report (NIR; for greenhouse gases). This methodology report describes the outline and backgrounds of the emission calculations with NEMA

Clinical handbook of air pollution-related diseases [Monograph]
Capello, Fabio \ Gaddi, Antonio Vittorino \ 2018
Environmentally induced diseases - Air Pollution - Environmentally induced diseases

This book examines in detail the clinical implications of those diseases that either are primarily triggered by air pollution or represent direct consequences of air pollutants. The aim is to provide medical practitioners with practical solutions to issues in diagnosis and treatment while simultaneously furnishing other interested parties with crucial information on the field. The book introduces the concept that air pollution-related diseases constitute a new class of pathologies. A wide range of conditions mainly attributable to air pollution are discussed, covering different body systems and pollution impacts in subsets of the population. In addition to presenting state of the art overviews of clinical aspects, the book carefully examines the implications of current knowledge for social and public health strategies aimed at disease prevention and prophylaxis. The Clinical Handbook of Air Pollution-Related Diseases will greatly assist doctors and healthcare workers when dealing with the consequences of air pollution in their everyday practice and will provide researchers, industry, and policymakers with valuable facts and insights.

Spatial patterns and mechanisms for terrestrial ecosystem carbon fluxes in the Northern Hemisphere [Monograph]
Chen, Zhi \ 2018
Carbon cycle (Biogeochemistry)

This book systematically illustrates the underlying mechanisms of spatial variation in ecosystem carbon fluxes. It presents the regulation of climate pattern, together with its impacts on ecosystem traits, which yields new insights into the terrestrial carbon cycle and offers a theoretic basis for large-scale carbon pattern assessment. By means of integrated analysis, the clear spatial pattern of carbon fluxes (including gross primary production, ecosystem respiration and net ecosystem production) along latitudes is clarified, from regions to the entire Northern Hemisphere. Temperature and precipitation patterns play a vital role in carbon spatial pattern formation, which strongly supports the application of the climate-driven theory to the Northern Hemisphere. With regard to the spatial pattern, the book demonstrates the covariation between production and respiration, offering new information to promote current respiration model development. Moreover, it reveals the high carbon uptake of subtropical forests across the East Asian monsoon region, which challenges the view that only mid- to high-latitude terrestrial ecosystems are principal carbon sink regions, and improves our understanding of carbon budgets and distribution. .

Termites and sustainable management. Volume 1, Biology, social behaviour and economic importance / [Monograph]
Khan, Md. Aslam \ Ahmad, Wasim \ 2018

This Volume comprises 12 chapters in an attempt to bring available information on biology, social behavour and economic importance of termites. Chapters in this book dealing with termites identification provide a review on most updated information of their systematics. Ecologically, termites interact with living and non-living surroundings and deliver a wide range of behaviors. In a separate chapter termites ecology is examined and explored. Termites depend on their gut microbes for digestion of complex polysaccharides of wood into simpler molecules. Information provided on termite gut microbiome and lignocellulose degradation constitutes an important contribution. Termite biology and social behaviour have been addressed comprehensively. Trail pheromones are responsible for the orientation and recruitment of nestmates to the food sources. Once arriving at a potential food source, termites assess its quality using a different set of cues. A separate chapter on trail pheromones, cues used during foraging and food assessment, with preferences for foraging sites, contributes a wealth of information. Emphasis has been given on reviewing ecological benefits of termites in other chapters. The information with respect to termite species as an edible insect and the overall role it plays in food and nutrition security in Africa is quite informative. A separate chapter dealing with importance of termites and termitaria in mineral exploration constitutes a significant step in addressing the economic importance of this insect group.

Wastewater Management Through Aquaculture [Monograph]
Jana, B. B. \ Mandal, R. N. \ Jayasankar, P. \ 2018
Environment - Aquatic ecology - Environmental law - Environmental policy - Environmental management - Sustainable development - Water Pollution - Aquaculture Environmental aspects - Sewage disposal - Water conservation - Water quality management

This volume provides state-of-the-art information on soil-water interactions in wastewater systems, characterization of wastewater, modes of treatment, safety of wastewater use, water conservation technologies involved in recycling of sewage in fish culture, biogeochemical cycling bacteria and nutrient dynamics, ecosystem resilient driven wastewater reclamation, bioremediation, aquaponics, ecological integrity, culture practices of fish farming, microbial food web phenomena, fish diseases, environmental economics of wastewater, environmental risk assessment, environmental law and regulations. Given its breadth of coverage, the book will be useful to researchers, teachers, students, administrators, planners, farmers and entrepreneurs interested in the profitable use of wastewater in the wastes-into-wealth framework of for the benefit of humanity, and in achieving the targets for sanitation and safe wastewater reuse by 2030, specified in the United Nations’ Sustainable Development Goals. Concerns are growing about the quality and quantity of fresh water, as severe crises are expected in the near future. Climate change has further worsened the strain on inland water resources, with its major impacts on ecosystems and human life. It is most urgent to protect and conserve inland water resources to maintain vital ecosystem functions. Despite the immense nutrient potentials of wastewater in terms of phosphorus, nitrogen and potassium and increasingly high rates of urbanization-based wastewater generation, wastewater has traditionally been overlooked as a resource. This produces a threefold loss – environmental degradation, monetary losses from fertilizers, and water. As a result, municipal wastewater offers a win-win strategy for water conservation and environmental protection, while also turning waste into wealth in the form of fish biomass and allied cash crops. Wastewater-fed aquaculture refers to a unique, integrated biosystem in which the wastes generated by the first system are used by the next subsystem. In wastewater-fed aquaculture biosystems, the organic wastes are recycled into fish biomass mediated through a complex microbial/autotrophic/heterotrophic food web mechanism. .

Food related land requirement and phosphorus balance of The Netherlands : appendix of report Closing the life cycle of phosphorus in an urban food system: the case Almere (NL) (report WPR-725) [Monograph]
Conijn, J.G. \ Dijk, W. van \ 2018

Recently, two studies were done that focussed on global and urban phosphorus (P) flows in the foodchain and land demand for food production: 1) a study aimed at exploring the possibilities of a localfood system and its effect on the phosphorus cycle for the urban region Almere and 2) a study inwhich the state of the global food system in 2010 was modelled with respect to land use, GHGemission, nitrogen and phosphorus cycling using the model BIOSPACS (Balancing Inputs and Outputsfor the Sustainable Production of Agricultural CommoditieS).In a separate study both models have now been applied to the Netherlands while focussing onphosphorus flows and land demand for the situation in which the Netherlands produces its own food(i.e. self-sufficient, except for exotic food products). In this report the assumptions and the results ofthe two new studies for the Netherlands are compared. We refer to these new studies by, respectively,Almere_NLD and BIOSPACS.Basis of the calculations for both approaches is the food intake and food supply (including foodwastage) to households. From that point the area demand for food production and associated P flowsare calculated based on crop and animal production data.For BIOSPACS the food intake and food supply data are derived from FAOSTAT (originating from CBS)and for Almere_NLD the food intake is based on data from the Dutch national food consumptionsurvey and, subsequently, food supply to households is calculated by assuming a wastage of 20%.Generally, in the analysis with BIOSPACS higher food supply rates are used for feeding the Dutchpopulation and more P needs to be ‘provided’, relative to Almere_NLD (average values for food: +27%and for P: +23%).Except for cereals and oil crops, the assumed crop yields used in Almere_NLD are higher than thosederived from BIOSPACS, especially for potatoes (+21%), pulses (+19%) and fruits (+59%). For theanimal production the feed requirement per unit animal product (FRR, feed requirement ratio)together with the crop yields determine the area and phosphorus demand. The FRR-values for pigmeat, poultry meat and egg production are comparable. For bovine meat and milk production theFRR-values calibrated in BIOSPACS are lower by using less roughages and concentrates.Despite different assumptions and data sources, the overall results are more or less comparable forthe two studies. This applies to the required area for agricultural production as well as the main Pflows. However, considerable differences in crop area demand between individual crops are calculated,and explained by differences in input values. BIOSPACS calculates a higher area demand for foodcrops while Almere-NLD calculates a higher area demand for animal production, resulting in a totalagricultural area demand that is comparable for the two studies. For a self-sufficient situation moreagricultural land would be needed compared to the amount currently in use for food production in theNetherlands. P flows in waste and P flows entering and leaving the city (households, retail, food processingindustry) were quite similar for both approaches. In agriculture larger differences are found due todifferent assumptions in the studies of BIOSPACS and Almere_NLD. In the latter most waste flowshave been assumed to be recycled towards agriculture, which has not been done for BIOSPACS.Furthermore, Almere_NLD assumes no P losses nor any accumulation of P in agricultural soils (crop Pdemand equals crop P offtake), contrary to the situation in BIOSPACS. However, when these twoconditions were also assumed for BIOSPACS, the required amounts of P fertiliser were more or lesscomparable

Uptake of pharmaceuticals by sorbent-amended struvite fertilisers recovered from human urine and their bioaccumulation in tomato fruit \ Water research : the journal of the International Association on Water Quality [Article]
Boer, M.A. de \ Hammerton, M. \ Slootweg, J.C. \ 2018
water pollution - water quality - water supply - waste water treatment - government policy - environmental policy - environmental legislation - air pollution - soil pollution - aquatic environment

Struvite precipitation is a well-documented method for recovering up to 98% of phosphorus from urine, which is one of the main nutrients in fertilizers besides nitrogen and potassium. Shortcomings of this process, however, are the low nitrogen recovery ratio and the possible uptake of pharmaceuticals from urine. In this work, the NH4+ adsorbent materials biochar and zeolite are coupled with struvite precipitation to increase the N-recovery of struvite from 5.7% to 9.8%. Since nitrogen is one of the main nutrients in fertilisers, this increase is of significance for its potential commercial use. In addition, urine is spiked with pharmaceuticals to measure the consequential uptake in struvite-based fertilisers and crops afterwards. Five fertilisers are prepared by nutrient recovery from spiked urine using: (1) struvite crystallisation, (2) struvite crystallisation combined with N adsorption on zeolite, (3) struvite crystallisation combined with N adsorption on biochar, (4) N adsorption on zeolite without struvite crystallisation, and (5) N adsorption on biochar without struvite crystallisation. The fertiliser with the highest purity product and the lowest uptake of pharmaceuticals was struvite combined with zeolite. Next, the contaminated struvite-sorbent fertilisers are tested in a crop trial in which the bioaccumulation of pharmaceuticals in edible plant tissue (tomatoes) is measured.

Air Lasing [Monograph]
Polynkin, Pavel \ Cheng, Ya \ 2018
Spectrum analysis - Remote sensing - Physics - Matter - Atoms - Atmospheric physics

This book presents the first comprehensive, interdisciplinary review of the rapidly developing field of air lasing. In most applications of lasers, such as cutting and engraving, the laser source is brought to the point of service where the laser beam is needed to perform its function. However, in some important applications such as remote atmospheric sensing, placing the laser at a convenient location is not an option. Current sensing schemes rely on the detection of weak backscattering of ground-based, forward-propagating optical probes, and possess limited sensitivity. The concept of air lasing (or atmospheric lasing) relies on the idea that the constituents of the air itself can be used as an active laser medium, creating a backward-propagating, impulsive, laser-like radiation emanating from a remote location in the atmosphere. This book provides important insights into the current state of development of air lasing and its applications.
