►Speech title "Sediment resources and eco-sedimentation"
Abstract-Sediment
is important resources. The world rivers carry 19 billion tons of
sediment to the river mouths and create more than 200 km2
of delta land annually. The gender of
deltas depends on the ratio of annual sediment load to the annual water.
A male delta develops if the ratio is high and the tidal currents are
weak. A female delta develops if the ratio is low. Male delta is
unstable and has only one or two channels flowing into the sea in
general. Female delta is stable and has multiple channels and numerous
islands. The aquatic ecology of female rivers is much better than male
rivers.
The economic development of deltas and coastal areas has resulted in
extremely high price of land. Artificial land creation with sediment has
been practiced in many countries. In female deltas the price of land is
extremely high because of navigation development. While in male deltas,
there are plenty of sediment resources. Therefore, artificial land
creation occurs both in female deltas and male deltas. The efficiency of
artificial land-creation is about 125 km2
per billion tons of sediment, more than 10 times that of natural
land-creation. The total area of artificial land in China has exceeded
10,000 km2.
About 60% of the 18,000 km long coastline of China have become man-made
coastline due to reclamation and land creation.
There is a lack of land in mountainous areas in southwestern China.
Sedimentation in barrier lakes made the river valley wide and flat,
creating land for agriculture and residence from mountains. The rate of
uplift Himalaya Mountains is different along the Yalongzangbu River
valley forming several rock barriers. Sedimentation has occurred in the
low uplift rate sections and stream bed incision has occurred in the
high uplift sections. As a result, about 500 billion m3
of sediment deposited in the high mountain river valleys over last
million years and more than 3000km2
of flat land have been created. The same stories occur in other river
valleys in western China due mostly to sedimentation in landslide dam
lakes.

►Speech title "Bacteria and fungi as bioinoculants: recent trends in the 21st-Century Sustainable Agriculture"
Abstract-The constant growth of the human population demands more and
more healthy foods. However, to produce such foods, a balance between
the environment and the society that produces them is required, this is
sustainable agriculture. And although the challenges may be diverse, in
this talk we will talk about the role that microorganisms associated
with plants play in stimulating the production and health of crops.
Laboratory and field studies have shown that plant growth promoting
bacteria and fungi, as they are widely known, exhibit mechanisms that
inhibit the growth of potential pathogens such as the production of
antibiotics, enzymes and metabolites that induce the plant's immune
system. Some of these compounds also help the plant take up nutrients
from the soil, which may not be bioavailable. These microorganisms also
produce phytohormones that regulate plant development, even under stress
conditions, including auxin, cytokinin, gibberellin, and ethylene.
Finally, there is a paradigm shift in current agricultural practices
around the world, and the use and application of bacteria and fungi as
bioinoculants (biofumigants or biostimulants) is part of that challenge.

►Speech title "Global convergence of non-linear responses in tree growth to climate change"
Abstract-Tree water use efficiency (WUE) has increased globally in the past 150 years, but this has not been translated into global increases in tree growth consistently in space and time. Complex and dynamic forest ecosystems would respond non-linearly to climate change with multiple factors over a long period, and can have tipping points or critical boundaries / thresholds at which a sudden shift to a contrasting dynamic regime might occur. However, prediction of such critical points / thresholds before they are being reached is extremely difficult. Indeed, our comprehensive studies undertaken in the last 15 years (mostly unpublished) have shown for the first time that long-term tree growth of beech and oak in temperate central Europe (Belgium) responded non-linearly to rising atmospheric carbon (C) dioxide (CO2) and water (H2O) limitation. This is due to the increasing mean annual temperature and decreasing summer rainfall during 1840s–1990s. It is the initial CO2 fertilisation and then warming-induced water limitation that control tree growth under climate change. This would result in decreased forest CO2 assimilation and increasing atmospheric CO2, leading to accelerated global warming and increasing water limitation. We have tested the CO2 fertilisation - warming-induced water limitation model globally, and our exciting major findings (unpublished) have highlighted that there is a global decline in tree growth beyond the tipping points of atmospheric CO2: average atmospheric CO2 tipping point at 327.5 ppm or reached in ca. 1972 for tropical tree species, with the corresponding mean tipping points of 340.5 ppm or 1981 (Mediterranean), 341.3 ppm or 1982 (temperate), 349.0 ppm or 1987 (arid), 353.7 ppm or 1990 (subtropical) and 363.5 ppm or 1997 (boreal). It is interesting to note that the atmospheric CO2 tipping points for a given biome (such as temperate) would be influenced by both biotic (e.g. tree species and age) and abiotic factors (e.g. water and N availability), but there is a global convergence of atmospheric CO2 tipping point at 346.0 ppm or in 1986, which is surprisingly approaching to the theoretical or model-predicted atmospheric CO2 tipping point of 350 ppm.

►Speech title "Novel Water Retention and Nutrient Management Technologies and Strategies Supporting Agricultural Water Management in Continental, Pannonian and Boreal Regions
Abstract-Urgent water and food security challenges, particularly in continental and boreal regions, need to be addressed by initiatives such as the Horizon 2020-funded project WATer retention and nutrient recycling in soils and streams for improved AGRIcultural production (WATERAGRI). A new methodological framework for the sustainable management of various solutions resilient to climate change has been developed. The results indicate that the effect of the climate scenario is significantly different for peatlands and constructed wetlands. The findings also highlight that remote-sensing-based yield prediction models developed from vegetation indices have the po-tential to provide quantitative and timely information on crops for large regions or even at the local farm scale. Verification of remotely sensed data is one of the prerequisites for the proper utilization and understanding of data. Research shows that current serious game applications fall short due to challenges such as not clarifying the decision problem, the lack of use of decision quality indicators and limited use of gaming. Overall, WATERAGRI solutions improve water and food security by adapting agriculture to climate change, recycling nutrients and providing edu-cational tools to the farming community. Farmers in small agricultural catchments benefit directly from WATERAGRI, but over the long-term, the general public does as well.

title "Bioelectroremediation: electricity driven biotechnology"
Abstract-Globally, thousands of sites are polluted by contaminants that could be bioconverted to a safer form. However, due to the absence of an electron donor or acceptor, or the right biocatalyst, the contaminants remain. Bioelectroremediation is a novel approach whereby microorganisms are using electricity or solid state minerals as electron donor or acceptor to drive the bioconversions. In the ELECTRA project (http://electra.site ), teams of the EU and China developed a multitude of approaches for different classes of contaminants, ranging from nitrates and chlorinated hydrocarbons to metals. The approaches either used an engineered technology, actively driving electrical current, or relied on electromicrobial concepts in which e.g. nature based systems were electrified passively. In my presentation, I will give an overview of the key approaches and outcomes of the ELECTRA project including some of the early data obtained from the pilot trials.

title "Numerical models for evaluating the competitive use of the
subsurface: the influence of energy storage and production in
groundwater"
Abstract-The subsurface is being increasingly utilised both as a
resource and as an energy and waste repository. Historically, there have
been few issues of concern related to competition between resources,
with groundwater contamination being a notable exception. However, with
increasing exploitation, resource conflicts are becoming increasingly
common and complex. Current issues in this regard include, for example,
the long-range impact of mechanical, chemical and thermal energy storage
on groundwater resources, and the complex effects surrounding hydraulic
fracturing in both geothermal and shale gas production. To analyse and
predict the mutual influence of subsurface projects and their impact on
groundwater reservoirs, advanced numerical models are necessary.
In general, these subsurface systems include processes of varying
complexity occurring in different parts of the domain of interest. These
processes mostly take place on different spatial and temporal scales. It
is extremely challenging to model such systems in an adequate way,
accounting for the spatially varying and scale-dependent character of
these processes.
In this lecture, we will:
• give an overview of possible utilisation conflicts in subsurface
systems and of how the groundwater is affected;
• review several model coupling concepts with a focus on the author’s
work in this field. The concepts are divided into temporal and spatial
coupling concepts, where the latter are sub-divided into multi-process,
multi-scale, multi-dimensional, and multi-compartment coupling
strategies;
• describe the fundamental properties and functions of a compositional
multi-phase system in a porous medium. The basic multi-scale and
multi-physics concepts are introduced and conservation laws formulated;
• explain the numerical solution procedures for both decoupled and
coupled model formulations. Two applications of multi-physics and
multi-scale algorithms will be presented and discussed;
• present a large-scale simulation that will show the general
applicability of the modelling concepts of such complicated natural
systems, especially the impact on the groundwater of simultaneously
using geothermal energy and storing chemical and thermal energy. At the
same time, he will show that such real large-scale systems provide a
good environment for balancing the efficiency potential and possible
weaknesses of the approaches discussed.

►Speech title"Environmental Microplastics and their Control Strategies"
Abstract-Plastics are currently used widely in our daily life; however, poor management and disposal of plastic wastes result in their ubiquity throughout the biosphere. The increasing accumulation of microplastics (MPs) or even nanoplastics in the aquatic, terrestrial and atmospheric environment has resulted in significant impacts on the life on land and in water. To date, there still lacks a comprehensive understanding of the sources, distribution, transport, and fate of MPs in different environmental compartments, which impedes the incisive establishment of efficient strategies toward addressing this problem. In this talk, I would like to discuss the wide issues of MP pollution and their control strategies and technologies. The proposed strategical solutions include cleanup strategies, targeted source control, improved plastic waste management, development of biodegradable (bio)plastics, and the investigation of various conversion/degradation approaches. I will also present the recent work of my group in conversion and degradation of MPs via catalytic processes.

►Speech title "The concept and pilot plant demonstration of new municipal wastewater treatment system using anaerobic membrane bioreactor and anammox"
Abstract-A
novel municipal wastewater treatment process towards energy neutrality
and reduced carbon emissions reduction was established by combining a
submerged anaerobic membrane bioreactor (SAnMBR) with a one-stage
partial nitritation-anammox (PNA), and was demonstrated in at the
pilot-scale at 25 oC, 20 oC and 15 oC. During the operation period,
excellent system performances were achieved. The Overall COD and BOD5
removal efficiencies at 25 oC were 95.1% and 96.4%, respectively, with
only 20.3 mg L-1 COD and 5.2 mg L-1 BOD5 were remaininged in the final
effluent. The total nitrogen (TN) removal efficiency was 81.7%, and the
resulting 7.3 mg L-1 TN was discharged from the system. The Biogas yield
rate was 0.222 NL g-1 COD removed with a methane content range of
78-81%. Approximately 90% of influent COD was removed in the SAnMBR, and
70% of influent nitrogen was removed in the PNA. The Denitrification has
which occurred in the PNA, which enhanced overall COD and nitrogen
removal. The successful operation of this pilot-scale plant suggest
indicates strong the feasibly of SAnMBR-PNA process is suitable for
application to the treatment of in real municipal wastewater.
In this research, a pilot-scale IFAS-PN/A succeed in the treatment of
actual MWW pretreated by AnMBR at decreasing temperatures from 25◦C to
20◦C to 15◦C, leading to the following conclusions: (1) Under the NLR of
0.21-0.24 kg-N/m3/d, the NRE decreased from 79.4% to 75.7% to 65.9% when
the operating temperature dropped from 25◦C to 20◦C to 15◦C,
respectively. The insufficient treatment capacity of AOB was blamed for
the sharp reduction of NRE at 15◦C.
(2) AnAOB were enriched in biofilm and retained by carriers, AOB were
mainly distributed in flocs and retained by the sedimentation tank. The
successful biomass retention and microbial segregation compensate for
the impacts of low temperature.

►Speech title"Prediction Approaches and Outstanding Issues in Sediment Transport over Land Surfaces and in Alluvial Channels"
Abstract-Sediment particles are, due to rainfall-runoff processes, carried from land surfaces to rivers and then to water receiving bodies such as lakes, estuaries, and reservoirs. During this journey, they can reduce fertile soil in agricultural areas, adversely effects navigation in rivers, and fill dead storage of reservoirs, reducing economical lifespan of dams. They can furthermore degrade water quality in rivers, lakes and reservoirs. Owing to its importance, sediment transport process has been experimentally and numerically studied for decades. The experimental studies have contributed significantly to understand the basic mechanics and dynamics of sediment transport. Yet, these studies, at the same time, led to the development of many empirical equations that differ mostly, even for the same flow conditions. The advances in computational technology have led to the development of more physics-based approaches that are often expressed by differential equations. Due to the constraints in data availability and parameter estimation, these approaches can vary from point-scale to areal scale. The physics-based approaches are fundamental when the concern is to predict the spatial and temporal variation of sediment. On the other hand, when the concern is just the sedimentograph, then most recently developed artificial intelligence methods, such as the artificial neural networks, the evolutionary search algorithms, and fuzzy logic, can be useful and practical tools since they do not require heavy computational burden. No matter which approach is employed, there are outstanding issues that are still a concern of research; particle fall velocity, particle velocity, sediment transport function, form roughness, grain roughness, incipient motion, suspended sediment concentration, and movable boundary.

►Speech title"Numerical modeling of groundwater recharge"
Abstract-Groundwater recharge is the process by which water infiltrating through the vadose zone from the land surface reaches groundwater table. Accurate evaluation of the recharge rates is crucial to estimate the amount of water which can be sustainably extracted from aquifers and vulnerability of aquifers to contaminant leaching from the surface. Among many methods proposed to determine groundwater recharge, numerical modeling is gaining popularity, partly due to its capability to assess the impact of climate and land use change on groundwater resources. However, calibration of numerical models is not a trivial task, which hampers their practical use. This presentation will be focused on selected aspects of calibration and application of vadose zone flow models, based on the studies of two experimental sites in northern Poland. Particular attention will be directed to the use of multiple types of data in model calibration.

►Speech title "How to achieve sustainable farm-scale anaerobic digestion for low-carbon agriculture: Irish experience"
Abstract-Using anaerobic digestion (AD) to recover biogas from agricultural wastes and by-products is an important solution to achieve a carbon-neutral agriculture. However, successful AD practice relies on sustainable feedstock, the way to use biogas, and effective management of digestate. In this presentation, the author will introduce the experiences and lessons learnt in Ireland, with a focus on digestate management. In Ireland, co-digestion of manure with grass silage and food wastes is economically feasible. Comprehensive quantitative analysis indicates that using AD, pig farms can transit from GHG producers to carbon-neutral. Local soil condition is a critical factor influencing the environmental sustainability of AD facilities, in particular soil phosphorus index. In order to make AD valid for areas where the local environmental regulation and soil nutrient conditions do not allow for direct land use of digestate, electrodialysis technology for nutrients (nitrogen and phosphorus) recovery from digestate, and dry digestion technology for separated solids digestion, are studied. Even though the presentation is based on the Irish context, the research questions discussed are recognised worldwide since the water-energy-food nexus, energy crisis and GHG emissions are global concerns.

►Speech title "Pet dogs and cats as sentinels of human exposure to environmental chemicals"
Abstract-Long term, low-level exposure to toxic environmental chemicals present in consumer products and foodstuffs can interfere with hormone function and contribute to the development of diseases and adverse health outcomes. To assess exposure to toxic chemicals to which people are exposed, many developed nations have implemented nation-wide biomonitoring programs. Biomonitoring is the direct measurement of people's exposure to toxic substances by measuring the substances or their metabolites in human specimens, such as blood or urine. Whereas biomonitoring programs are gaining popularity in public health programs of regulatory agencies throughout the world, several logistical and ethical issues such as access to human populations to biospecimens such as blood and urine hinder the progress. Pets share a living environment with humans and are exposed to a wide range of environmental toxicants present in the indoor environment. Especially, pet cats and dogs have been used as sentinels of human health effects of chemical exposures. Several studies have documented the association between chemical exposure and pet health. For instance, in Minamata Bay in Japan during the 1950s, neurobehavioral symptoms were first observed in cats that consumed mercury-contaminated fish. Studies have showed a relationship between concentrations of organohalogen contaminants and diabetes in cats. Earlier studies have linked chemical exposure in pets to major diseases such as hypothyroidism, obesity, kidney diseases and cancers. A few studies have reported the prevalence of exposure to pesticides in pet dogs and cats. We collected urine from pet dogs and cats from Albany, New York, USA, and analyzed for a wide range of environmental chemicals including phthalates, bisphenols, parabens, melamine, aromatic amines, volatile organic compounds and glyphosate. Pet cats and dogs are ubiquitously exposed to a wide range of toxicants and the measured values are similar to and in some cases highest than those found in humans. The measured values were used to assess total exposure doses and risks. We show that pet animals are at risk from high exposure to some toxicants.

►Speech title "Vegetable Uptake and Accumulation of Pharmaceuticals and Personal Care Products from Water and Soil"
Abstract-Land application of animal manure/biosolids and irrigation with treated wastewater in agricultural practice could disseminate pharmaceuticals and personal care products (PPCPs) in the agroecosystems. The wide use of these waste resources benefits the agricultural production, such as improving soil quality, providing plant nutrients, convenient disposal of waste, and saving valuable water resource. However, the accompanied PPCPs can enter the soil environment, and accumulate in field crops and vegetables, which could pose potential risk to human health. Most PPCPs can enter plant from root uptake, with the accumulation determined by PPCPs properties, transpiration flow and their metabolism in plant. Soil pore water is the major carrier for PPCPs transport from soil to plant. Increasing transpiration stream moves more PPCPs to plant leaves. A better understanding of the fate of PPCPs in soil-water-plant systems is critically needed to model the transport of PPCPs in the environment, and evaluate their impacts to food safety and potential risks to human health.

►Speech title "The biogeochemical effects of drought and its implications in a changing climate"
Abstract— Droughts are increasing in frequency and severity in many regions of the world due to climate change. The aim of this presentation is to provide an overview and examples of how droughts are changing biogeochemical processes in catchments, estuaries and coastal oceans. Many of the biogochemical changes during drought can be linked to changes in hydrological conditions such as drying of wet soils, reductions in surface and groundwater levels and flows, diminished floodplain wetting cycles, and reduced outflows from river systems. Increased temperature and evaporation rates due to climate change are also influential. Several case studies will be presented from the Murray-Darling Basin, Australia’s largest river system, which experienced the extreme ‘Millennium Drought’ from 1997 to 2009. In some instances the system and ecology has not readily recovered from this drought which points to alternative geochemical states being a likely consequence of climate change.

►Speech title "Value-added technologies of water treatment wastes recycling"
Abstract— Even though today the majority of waste is recycled, some of it is still largely stored. Water treatment process wastes are one of these wastes. They can be utilized in place of several commercial reagents and raw materials since, unlike most wastes, they don't include toxic fillers. Sediments after coagulating surface waters containing calcium carbonate, iron, or aluminum hydroxides, as well as waste lime mad, are examples of water treatment wastes. Other types include used ion-exchange resins and coals, as well as precipitation from the deionization process in membrane installations. For the processing of each of the aforementioned wastes, we have suggested a number of options. Nanostructured photocatalytic materials for wastewater materials were made from iron removal precipitates, and filtrates including calcium, magnesium, sodium, potassium, and sulfur were employed as a good complex fertilizer. Additionally, technology has been developed for the one-stage, room-temperature, atmospheric-pressure to manufacture calcium sulfate anhydrite from lime mad. Technologies have been developed to process used ion-exchange resins thermochemically, producing a combination of di- and trimethylamine as well as liquid fractions with calorific values as high as 43 MJ/kg. Spent ion-exchange resins were processed to produce very efficient coagulants. They underwent testing for the technology of sewage sludge dewatering and the removal of organic and inorganic contaminants from wastewater. A detailed assessment of the potential use of waste in the manufacture of ceramic building bricks and blocks was done. All developed technologies are cost-effective. Technical requirements, technological restrictions, and feasibility studies have all been produced for the majority of the elaborated approaches.

►Speech title "Extreme gas pressures in lakes: from the killer Lake Nyos to methane deposit in Lake Kivu"
Abstract-Several lakes show extreme loads of gases in their deep water.
In most cases, volcanic sources are responsible for the high gas charge
but also geochemical processes and decomposition of organic material
have created gas loads of concern.
We report, how reliable measurements of extreme gas loads could be
accomplished. In the case of Lake Kivu 40 billion m³ of exploitable
methane could be substantiated, while in Guadiana Pit Lake carbon
dioxide loads of nearly three liters of gas per liter of lake water were
detected. We report about possibilities to confirm high gas loads by
direct measurements of gas pressure or sound speed. In the case of
Guadiana Pit Lake, authorities followed the recommendation to remove the
gas load artificially to avert the danger of a limnic eruption, while in
the case of Lake Kivu, prescriptions for the survey of the lake have
been issued by an international expert team for the period of methane
exploitation. Finally, we show results from noble gas thermometry for
the deep water of Lake Kivu to quantitatively separate the effect of
equilibration temperatures from possible previous gas evasion by large
scale ebullition.
