Abstract:

Anthropogenic groundwater exploitation essentially changes soil moisture, land-atmosphere water and energy fluxes, even climate system. In over-exploited regions, the terrestrial water storage has been rapidly depleted, causing water unsustainability and climate change. Quantifying the hydrologic and climatic responses to anthropogenic groundwater extraction not only advances our understanding on the hydrological cycle with human intervention, but also benefits effective human water management. In this paper, the authors incorporated a scheme of anthropogenic groundwater exploitation into the Community Earth System Model 1.2.0, and conducted a series of simulations over globe to investigate the effects of groundwater exploitation on the hydrological processes and climate system around the world. The framework of the coupled model are shown in Fig. 1. The model was also applied over Heihe River Basin in northwestern China for investigating the impacts of water use and groundwater lateral flow on basin-scale land processes, and the eco-hydrological effects of stream-aquifer water interaction over riverbanks. Results show that groundwater exploitation caused drying in deep soil layers but wetting in upper layers, with a rapidly declining water table in areas with the most severe groundwater extraction, including the central United States, North China Plains and the north India and Pakistan. The atmosphere also responded to groundwater extraction, with cooling at the 850 hPa level over the north India and Pakistan and a large area in North China and central Russia. Increased precipitation occurred in North China Plains. Decreased precipitation occurred in north India because the Indian monsoon and its transport of water vapor were weaker as a result of cooling induced by groundwater use. Local terrestrial water storage was unsustainable at the current high extraction rate. Thus, a balance between reduced water withdrawal and rapid economic development must be achieved to maintain a sustainable water resource, especially in over-exploited regions.

Abstract:

The Santa Lucía village (Lat.: 43°24'50''S – Long.: 72°21'59''W; 236 m.a.s.l.) is located near to the Frio River, Lake Region. This village has risks considering the natural system dynamics of the place where it is located; a wide and deep glacial valley surrounded by mountain chains with summits 1700–1800 m.a.s.l., where there are several glaciers. The analysis of the geographic surrounding of the Santa Lucía village reveals that there exist potential hazards in the nearest associated with the geomorphology and the glacial context of the upper Frio River valley. These threats are related to four glaciers that have proglacial lagoons and to the effect of the warming tendencies, with the consequent ice structural stability loss, meaning potential scenery of GLOF’s occurrence, and a possibility of a disaster for the village. The climate of the zone is characterized by considerable temperature variations, with more than 20°C in summer, and <0°C in winter, and by 3000 mm of precipitation. In summer 2017, a debris flow was triggered by a 122 mm/24 hours precipitation; intensity that is the double of the 60 mm/24 hours stablished by Hauser (1985) for the occurrence of mass movements in central Chile. This rain, that unchained a slope-slide and then a debris flow, happened over 1400 m.a.s.l., indicating where the high of the 0°C isotherm was during the event. Because no temperature information, the MODIS thermal sensor data gives the possibility to approximate the altitude and the tendency of the 0°C isotherm, process directly ligated to the occurrence of GLOF’s. According to the results of the thermal sensor data for the 2001–2017 period, the height of the 0°C isotherm was increased in ±400 m. This result, not sufficient accuracy (R²=0.3342), can be associated with an increase of the potential hazard of GLOF’s, and constitute information for the determination of a new location for the Santa Lucia village.

Abstract:

Since 2011, Pan-American Observatory of Landscape, Territory and Architecture (OPPTA) works simultaneously on risk cause by the impacts of climate change and natural hazards in five Latin American cities. The number of unexpected and unprecedented effects of climate change and natural disasters affecting the Latin-American sub-continent in a short period of time motivated OPPTA to develop a concurrent methodology of research proposals and action to approach infrastructural, architectural, landscape and social actions, improving living condition, minimizing vulnerability and promoting the resilience of cities and communities. The proposed methodology is based on the development of five programs: active debates, competition, priority action, WikiPan and publications, which deal respectively with: research, design and implementation of projects, and the creation of an open database and publications to disseminate the results. This methodology settles mechanisms and processes to work through a multidisciplinary and transnational network along Europe and America, involving researchers, professionals and institutions, of both public and private sector. The aim of this research includes the study of risk and its associated problems to identify patterns, concurrencies and differences at the technical, infrastructural and political (identification of public policies and governance in Latin America) level. Among the 12 initial candidates, five sites have been selected: Chimalhuacán (Mexico), Lima (Peru), Puerto Saavedra (Chile), San Cristobal (Colombia) and Petropolis (Brazil). The particular context and specific problems associated to each site stimulate a simultaneous search for common solutions to ensure an effective adaptation. As a result, the technical proposals were implemented throughout the Priority Action Programme, which incorporates sustainable and resilient development plans and project; design of public infrastructures to minimize vulnerability; networks of resilience green-public areas; organization of educational programs and citizen participation with regards to urban agriculture and horticulture, waste and water management; etcetera, to ensure mitigation and endangered environment preservation.

Biography:

Chia-Fa Chi is a Doctoral Candidate of the Department of Marine Environment and Engineering in National Sun Yat-sen University, Taiwan. His main research activities are focused on adaptation to climate change in coastal areas. In particular, he is interested in the issues of maladaptive risks. He has received awards of the Graduate Students Study Abroad Program which is sponsored by Taiwan Ministry of Science and Technology and National Sun Yat-sen University, separately.

Abstract:

As the practice of climate change adaptation has developed rapidly over recent decades, so has the evidence of maladaptation associated with adaptation initiatives, particularly in the form of risk transfer and risk substitution. Increasing our understanding of maladaptation is important so as to avoid negative outcomes of adaptation project implementation. However, as a research topic, maladaptation has received limited attention to date. Previous research has focused on the development of conceptual frameworks that can assist in defining and evaluating maladaptation, which can be applied to adaptation planning processes seeking to avoid maladaptation. However, practical case studies and methods which can assess and evaluate the risk of maladaptation by integrating both spatial and temporal aspects in a simulation tool have not been done to date. This paper aims to fill this gap by exploring the existing knowledge on maladaptation to climate change, and the interaction between land use change, adaptation planning and project design with the purpose of extending our conceptual understanding. We adopted a systematic review method which involved considering several questions including: (a) What are the definitions and categories of maladaptation? (b) What methods and theoretical frameworks exist for the assessment and evaluation of the risks of maladaptation? (c) How have climate-related research communities considered the issues of maladaptation? (d) What are the experimental studies on land use change which could be applied to minimize the risks of maladaptation in the future adaptation planning? We conclude that future research on maladaptation should integrate spatial analysis methods to assist the identification of maladaptation risk at the initial stage of adaptation planning.

Abstract:

Climate change has varied impacts on diverse livelihood sectors, which is more prominent at the community level. The stakeholders and local institutions have been supporting the communities either by building adaptive capacities and climate resilience or minimizing the impacts through different adaptation interventions. Some of these interventions are effective, whereas others need further dynamics and exertions considering the complexity of the climate risks and vulnerabilities. Hence, consolidated efforts of concerned stakeholders are required to minimize the present and future climate impacts. This study digs out and analyzes the perceptions of local stakeholders on climate change adaptation in Madi and Deukhuri valleys of Nepal through a questionnaire survey. These local stakeholders revealed flood, drought, cold wave and riverbank erosion as the major climatic risks and hazards found in the sites eventually impacting on the loss of agricultural production, loss of agricultural land and properties, loss of livestock, the emergence of diseases and pest. The stakeholders believed that most of the farmers dealing with these impacts were based on their traditional knowledge and practices, followed by with the support of NGOs and with the help of neighbors and community. The major supports of the stakeholders to deal with these impacts are on training and awareness, risk analysis and minimization, livelihood improvement, financial support, coordination and networking and facilitation in policy formulation. The stakeholders perceived that capacity building, appropriate technologies, community-based planning, prioritization of poor and marginalized, community fund and community-based monitoring, and evaluation were the most important supports required for the community, respectively.

Abstract:

Statement of the Problems: It has been scientifically proved that the emission of human-induced greenhouse gases is the major contributor to climate change. A variety of strategies are being implemented to reduce the emission of human-induced greenhouse gases at a global, national and regional level for achieving low-carbon and carbon-neutral society. However, the ultimate goal of climate change strategy is to achieve carbon-free society which is the state of, climate before industrialization advanced in the 18th century. Nonetheless, it is quite rare to establish the framework of carbon-free society.

Contents of Presentation: In the context mentioned above, this paper will present a framework for achieving carbon-free society through overcoming the limitations inherent in the existing framework promoting low-carbon and carbon-neutral society. The presentation will be composed of three parts. First: The difference in the concept and implication of low-carbon, carbon-neutral and carbon-free society will be examined. Second: The limitations inherent in the low-carbon and carbon-neutral frameworks will be critically examined in terms of their strategies for achieving the state of climate before industrialization has been advanced in the 18th century. Third: A framework for achieving carbon-free society will be presented in a way to overcoming the limitations inherent in the existing low-carbon and carbon-neutral frameworks, focusing on overall direction of nature-based and technology-based approach, major socio-economic sectors and strategies to be included, and methodologies for analyzing the efficiency and effectiveness of the strategies.

Conclusion & Significance: No country/region currently has all requirements necessary for promoting carbon-free society. In this context, as a concluding remark, what capacity should be built will be discussed. In a word, the key significance of the presentation is in seeking for the direction and contents of achieving carbon-free society which is the ultimate destination of climate change strategy.

Kozarcanin Smail is passionate in understanding and proposing ways of how the humanity is able to mitigate climate change during the 21st century. This interest has led him to join the Aarhus University, Sustainable Energy System group where he is employed as a PhD Fellow. He has his expertise within the subject of climate change impacts on future highly renewable large scale energy systems.

Abstract:

Increasing global warming and the resulting climatic changes are likely to advance the weather-related risks that are facing many different human and natural systems. In the attempt to cushion these effects, mitigation strategies that rely on low-cost weather driven variable renewable energy technologies are gaining ground, and installed renewable energy generation capacities are increasing significantly. We present a study on, to what extend the weather is changing in a way that also directly impacts the best system design decisions for weather-driven sustainable energy systems. The latest generation of IPCC’s climate projections, RCP2.6, RCP4.5 and RCP8.5, have been used to represent a broad range of climate outcomes during the 21st century. These are strongly influenced by climate policies representing the latest Paris agreement, imposition of high global greenhouse gas emission prices and lack of climate policies, respectively. On behalf of the EURO-CORDEX project, three hourly climate data have been provided from six different high-resolution regional climate models for Europe. We have then applied state-of-art methods to generate bias corrected wind and solar power production time series for the 21st century, and to correct the electric consumption profiles for heating and cooling for 30 European countries. To assess the far future impacts of climate change, the production and consumption profiles are applied to a fully connected, highly-renewable, large-scale European energy system. As a result, we found small changes in the relevant energy system key metrics of the combined system dynamics compared to historical values. We concluded that the effect of climate change can most likely be ignored in the context of energy system design for the 21st century. However, in correspondence with the literature, impacts of climate change are more prominent through the demand and these strongly outweigh the energy supply side impacts.

Abstract:

Tons of chemical compounds derived from human and industrial activities are incessantly threatening our environment.  Current approaches for monitoring of pollutants include precise and accurate assessment of individual compounds by chemical analyses, which are however unable to provide information about bioavailability, effect on living organisms, and synergistic or antagonistic behaviour in mixtures, thus requiring combination with biomarker assays and ecosystem monitoring. These methodology strategy is time and labour intensive, demands ex-situ collection at individual locations and extensive sample preparation, and has elevated costs depending on the complexity.

To overcome these challenges, biosensor and bioassay technology can furnish advanced devices for water monitoring with greater efficiency. Indeed, integrated, cost-effective, easy to use, and fast biosensors can be projected to characterize the extent of pollution at relevant spatio-temporal scales and in terms of ecological effects. Despite this great potential, most of the published works focused on analyses of fresh water, mainly because of the highly demanding working environment that seawater constitutes. To face the challenges posed by real environments, biosensors need to be fully automated, very robust (resistant to physical impacts, high corrosion, and biofouling), drift-free or with accurate calibration, with minimal power consumption, user-friendly, and enough sensitive to measure pollutants at very low concentrations. Several examples of biosensor development for marine measurements of eutrophication, pesticides, anti-biofouling agents, polycyclic aromatic hydrocarbons, endocrine disruptors, trace metals, organism detection and algal toxins have been described in literature.

Algal biosensors react very broadly to toxicity and their detection mechanism frequently relies on measurement of the photosynthetic activity caused by 33% of pesticides actually in the market. Biosensing applications of photosynthetic organisms are based on the inhibition of the electron transfer occurring after a few minutes exposure of photosystem II (PSII) to certain pollutants, or to adverse physicochemical conditions changing the local chemical equilibrium. Indeed, when pollutants such as photosynthetic pesticides are present and encounter the photosystem, they can bind the reaction centre D1 protein and directly or indirectly inhibit the transport of electrons from the primary acceptor, plastoquinone A (QA), to the secondary quinone (QB) along the photosynthetic chain. This inhibition results in a variation of PSII fluorescence emission in a pollutant concentration-dependent manner that can be monitored by optical transduction. Based on this approach, several microalgal biosensors have been designed for pesticide and heavy metal detection in fresh water. However, hyper-saline conditions present in marine environment and stress conditions during environmental monitoring may affect the photosynthetic process resulting in significant changes in the bioassay performance. Herein we present the development of an optical bioassay for detection of photosynthetic pesticides from different chemical classes in real water samples by exploiting various green microalgae strains. Therefore, the main objectives were to select the most appropriate microalgae strains to achieve stability and adaptability into real matrices, and to develop a bioassay integrated with portable fluorescence instrumentation allowing pesticide detection at relevant environmental concentrations. Several microalgae species from Chlorophyceae, Trebouxiophyceae, Dinoflagellates, Diatoms and Eustigmatophyceae groups with different marine and non-marine origins, including fresh water and soil, were analysed. Lipid content of selected microalgae suggested that C. mirabilis and symbiotic associations between C.vulgaris and protozoa were the microorganisms with higher potential to acclimate to high salinity environments being mainly constituted by unsaturated lipids involved in responses to several environmental stresses.

Among the wide range of microalgae species, which have been employed to develop biosensor technology, Chlamydomonas reinhardtii was especially studied since it possess a number of features that suite perfectly the requirements of an early warning environmental biosensor. It is a grass organism, easily cultivable having 8 hours doubling time and it can grow with or without carbon source, besides, it is easily transformable and all 3 genomes are sequenced. Recent our efforts have focused on increasing the stability and selectivity of PSII from microalgae for the detection of different subclasses of pollutants. These goals were achieved by using the alga C. reinhardtii mutated at the D1 protein herbicide-binding site by site-directed mutagenesis. C. reinhardtii was also modified introducing in the chloroplast antioxidant peptides, known in food able to reduce the content of free radicals, thus lessening the photooxidative membrane damage. Measurements of in-vivo antioxidant activity showed that mutant strains have improved their survival rate in the presence of singlet oxygen precursors, which highly exceeds the survival rate of control algae, showing increased stability and sensitivity for biosensor applications.

Beyond these scientific achievements, nowadays the market needs highly specific and precise in situ measurement devices able to collect and send the data in real-time for periods of months without maintenance under multi-stressors. These devices demand more robust algal biomediators. Thus, the challenge is the preservation of the algal photosynthetic functionality when integrated with electronic components or operated under fluctuating environmental conditions. To this end C. reinhardtii mutants able to quench 1O2 and other ROS, were integrated into a newly developed miniature and portable electrochemical/optical device, to measure and collect PSII  data in real-time for long periods.  Several photosynthetic pollutants spiked in real samples were detected within 10 min in concentrations between ng/L-μg/L and the different algae species tested showed diverse pesticide sensitivities.

Always towards to increase the biomediator performance, biomimetic peptides of the photosynthetic D1 binding niche of the microalgae C. reinhardtii were developed, both by chemical and biological synthesis, as suggested by in silico analysis. Standing out among the others, the biomimetic mutant peptide, D1pepS268C, bound to specific quantum dots, showed high ability to mimic the microalga in binding pesticides. Replacement of whole microalgae cells or their photosynthetic apparatus by mimetic peptide improved the system in terms of stability.

This approach allowed also the integration of the biomediators with quantum dots and innovative stretchable printed electrodes-based electrochemical biosensor as a wearable point-of-use screening tool for toxicity environmental analyses.

Farasani A received his PhD from Reading University, UK in 2016 for his work on genotoxicity of cosmetic chemicals in human breast epithelial cells. He is currently working as Head of Genetic Unit in the MLT Department at Jazan University, Saudi Arabia.

Abstract:

Dermal absorption of components of underarm cosmetics may be a contributory factor in breast cancer development. Aluminium (Al) salts are added as the active antiperspirant agent, and cyclic volatile methylsiloxanes (cVMS) are used for purposes of conditioning and spreading. Al has been measured in human breast tissue, breast cyst fluid, nipple aspirate fluid and milk: Al levels in breast tissue have been recently reported to be a risk factor for breast cancer in young women. cVMS have been measured in human milk. The objectives of this study were to investigate any genotoxic effects of exposure to the antiperspirant salts Al chloride and Al chlorohydrate, and to the cVMS hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) in immortalized non-transformed human breast epithelial cells. All these compounds enabled a dose-dependent growth of the non-transformed cells in suspension culture, which is an established marker of transformation. DNA damage was demonstrated using a comet assay. Long term (≥20 weeks) exposure to these compounds also resulted in loss of expression (mRNA and protein) of the breast cancer susceptibility gene BRCA1 which is a key gene in the repair of DNA in breast cells. Alterations to expression of other DNA repair genes at an mRNA level will be presented. If these compounds can both damage DNA and compromise DNA repair systems, then there is the potential for breast carcinogenesis.

Abstract:

Background: Measurement of pesticides in biological matrices is a serious challenge for researches because of their very low concentration in different matrices. The aim of this study was to develop a new sample preparation method with high accuracy, validity, simplicity as well as a short retention time for chromatographic determination of the pesticide malathion.

Methods: Dispersive liquid-liquid micro-extraction (DLLME) technique coupled with high performance liquid chromatography equipped with ultra violet detector (HPLC-UV) was developed for trace extraction and determination of pesticide malathion in human urine samples. One variable at a time (OVAT) method was used to optimize parameters affecting the malathion extraction. Different parameters such as extraction solvent, disperser solvent, and volume of the extraction solvent, volume of the disperser solvent, centrifugation time and speed, salt addition, and sample pH were studied and optimized.

Results: Under the optimized conditions, the limit of detection and enrichment factor of the developed procedure were 0.5 µg L-1 and 200, respectively. The calibration curve was linear in the concentration range of 2­­­­–250 µgL-1. The relative standard deviation for six replicate experiments at 200 µgL-1 concentration was less than 3%. The relative recoveries of spiked urine samples were 96.3%, 101.7% and 97.3% at three different concentration levels of 50, 200, and 1000 µgL-1, respectively.

Conclusion: According to the obtained results, DLLME procedure was successfully developed for the extraction of malathion from human urine samples. Compared to other extraction techniques, the proposed procedure had some advantages such as shorter extraction time, better reproducibility, and higher enrichment factor.

Biography:

Angela Pinzon-Espinosa is a Water Scientist working at the interface between Microbiology and Chemistry. Her research interests are directed towards the link between water quality, health, and environment, and the different strategies to tackle water pollution. Her current research focuses on the detection and identification of toxic chemicals in industrial effluents using luminescent bacteria, and the development of low-cost clean-up technologies targeting refining chemicals. She is particularly interested in the science behind pollution control and the use of science for regulatory purposes, but keen on expanding her expertise to environmental management aiming to provide clean and safe water.

 

Abstract:

Refining transforms crude oil into marketable products with high commercial value, providing a third of the global energy requirements and numerous raw materials. The process, however, emits vast amounts of wastewater that can have harmful effects on wildlife and human health but the link between chemistry and observed toxicity is fragile because little progress has been made in determining causative agents. Consequently, current treatment technologies are not targeting key toxicants nor providing safe effluents. Here we show that naphthenic acids are important components of refining wastewater, resulting from the processing of heavy crude oil, and that they have an important contribution to the toxic effects exerted by these effluents. Furthermore, we found that their chemical stability makes them highly resistant to remediation using bacteria and Fe-TAML/H2O2 systems under laboratory conditions, and only sequential aliquots of Fe-TAML catalysts and H2O2 showed to degrade naphthenic acids (50 ppm) within 72 hours. We anticipate our results to be a starting point for better environmental regulations relevant to refining wastewater resulting from heavy crude oil, as naphthenic acids are not currently considered in the effluent guidelines for the refining sector. Furthermore, the degradation of naphthenic acids under mild conditions using Fe-TAML/H2O2 systems indicates that these catalysts hold promise for the remediation of refining wastewater in real-life scenarios.

Jianhua Yao has her expertise in Chemoinformatics and its applications in all domains which relate to Chemistry. She has studied prediction of compounds properties for more than 10 years and developed prediction system of acute toxicity, mutagenic toxicity and carcinogenic toxicity. These systems have been applied in environmental protection.

Abstract:

A compound is a chemical entity consisting of two or more different atoms combined by chemical bonds. Their properties are basically physical, chemical, biological, toxicological, etc., and depend on their chemical structure. Toxicity is one of the properties of compounds, and is related to their chemical structures. Toxicology involves the study of the adverse effects of chemical substances on living organisms and is a discipline related to biology, chemistry, pharmacology, medicine, and nursing. Its research content includes: symptoms, mechanism, treatment and determination of poisoning. Generally, in toxicology, there are six types of toxicity: acute, mutagenic, irritative, carcinogenic, reproductive, and multiple doses. To obtain the toxicity evaluation of compounds, traditionally, people evaluated their toxicities by microbiological, animal experiments, or got them from human events reports. With the increment of experimental data, development of computer science and chemoinformatics technology, computer aided prediction toxicity of compounds become another effective way to obtain information about toxicity of compounds step by step. At present, it is being applied in related fields, such as chemical toxicity assessment concerning environmental protection, food industry, study of TCM (traditional Chinese medicine), agricultural production and pharmaceutical industry, and plays a key role. Actually, in computer aided prediction toxicity of compounds, combination of data mining, analysis of relationship between reliable experimental data and chemical structures was used to obtain the knowledge/rules which would be employed to predict toxicity of a compound based on its chemical structure. Herein, two works of our group will be presented: strategies and methods of computer-aided prediction of toxicity and; evaluation of toxicity for a pesticide and its metabolites, formulating plans of environmental protection.

Title: Differences in PM2.5 from various combusted materials

Time : 16:50-17:10

Biography:

Fawei Yan, Master of Engineering, ever studied in School of Natural Resources and Environment, Renmin University of China, majoring in Environmental Science from 2014 to 2017. During school time (2010-2017), he participated in many research programs, for example, PM2.5 Formation, Lignocellulose Degradation (Microorganism), Waste Combustion, Soil Analysis and so on. Especially, he took part in the research Antibiotics Degradation in Water in University of Nebraska Lincoln, USA for almost 2 months in 2013. Now he work in the Planning and Development Department, Beijing New International Airport. He has his expertise in Environment Research such as PM2.5, waste combustion. His research interests are PM2.5 Generation and Green Airport.

Abstract:

PM2.5 now is a very hot topic in China and the government is taking sustained efforts to resolve this problem. Especially, in Beijing, restricting vehicles, restriction on constructions, closing low-end factories that contaminate the environment, are several means to reduce the PM2.5 generation by all respects. However, PM2.5 emerges from many sources, including natural and anthropogenic discharges. One of the main anthropogenic sources is combustion. Fuel burning is a very important source. Many researchers have deeply studied the formation of PM2.5 from coal combustion or oil combustions. However, the research on PM2.5 from other combustions is a rarity. Hence, several materials were combusted including plastic, wood and glass as the research subjects in the same operation condition in this study. These three represent three kinds of materials, chemical organic matter, organic biomass and inorganic matter. Information such as PM2.5 production and PM2.5 morphology were collected. The findings suggested that different wastes would exhibit different PM2.5 emission potentials in the same combustion operation condition and the morphologies of PM2.5 from various combustion sources is also identifiable. Plastic combustion bears the highest PM2.5 discharge potential during incomplete burning with tremendous spherical particulates in the images. Glass bears no PM2.5 discharge potential for its incombustible properties. While wood would generate PM2.5 in an irregular shape with a moderate production.

Title: Synthesis of heterogeneous catalyst for biodiesel production from cooking oil
Biography:

Abstract:

Biodiesel, a promising alternative diesel fuel produced by a catalytic transesterification of vegetable oils, has become more attractive nowadays, because of its environmental concerns and the fact that it is made from renewable resources. In this work, the trans-esterification of soybean oil with methanol has been studied in a heterogeneous system, using Zn, Mn, K and Ce supported by a mixture of porcelain, cinder and ceramic. 0.5 and 1 mm of Zn, Mn, K and Ce in 7 g of support were loaded, followed by calcinations at 600°C for 4h. Fresh and used catalyst were characterized by means of various spectroscopic techniques such as scanning electron microscopy (SEM) and TG conversion was checked by HPLC. It has been observed that 1M ZnCO3 loaded in the support gives 93% TG conversion.

Title: Impacts of climate change on the incidence of morbidity
Biography:

Rachida El Morabet holds a PhD in Biology from the Mohammed V University, Rabat, Morocco (2004), an Inter-University Diploma in Biotechnology, Paris, France (2001) and a University Pedagogy Certificate (teaching practices; learning theories; models assessment practices knowledge; educational resources and distance learning) (2014).

She received two gold medals with Honors of International Exhibition of Invention and Innovation, Casablanca, Morocco.

Abstract:

Human health is seriously affected by the impacts of climate change. WHO (World Health Organization) and IPCC (Intergovernmental Panel on Climate Change) have published several reports describing negative impacts of climate change on human health; this has resulted in the epidemiology of many diseases and conditions. Climate change has both direct (psychological effects arising from cold, heat and extreme weather) and indirect (change in behavior, forced migration etc.) impacts on human health. In 2015, WHO confirmed that floods cause contamination of freshwater sources, increases the risk of water borne diseases, provides breeding places for vectors of infectious diseases. In Morocco, the intensity and recurrence are enhanced due to climate change is a worrying phenomenon in recent years as the loss of life and property has increased. The rise in temperature additionally adds to this problem as it exacerbates diseases and number of deaths. The impact on health varies from region to region within a country partly due to geographic conditions. The nature and scale of impact will depend on the buffer capacity of the health systems (adaption and initial access of population to health services). Extreme weather conditions can result in requirement of health services which may surpass the capacity of existing health facilities rendering them vulnerable in future. The findings make a case for the Moroccan national health strategists to recognize the importance of overcoming major health risks presented to the population and citizens of Morocco. This can be achieved by identifying climate risks for health as a major challenge to be overcome in order to provide maximum protection of human health of citizens against these threats.

Title: Climate warming shifts Indian monsoon season: Evidence from observation
Biography:

Elena Surovyatkina has her expertise in Theoretical Physics in the field of Theory of Critical Phenomena. She has contributed to the understanding of critical transitions with the new theory of nonlinear pre-bifurcation noise amplification and rate-depended phenomena. She discovered a new phenomenon of overcooling and overheating of critical temperatures in liquid crystals. Currently, her research is devoted to the spatially organized critical transitions in climate. The most significant contribution in climate dynamics is a new methodology of the earliest forecast of the Indian summer monsoon.

 

 

Abstract:

Statement of the Problem: The Indian summer monsoon is the season of rain. The economy of India can maintain its GDP in the wake of a good monsoon. However, if monsoon gets delayed by even two weeks, it can spell disaster because of the high population depending on agriculture—70% of its people are directly related to farming. In Central India, the variability of monsoon is quite high due to local changes such as rapid urbanization and industrialization. The forecasting of climate phenomena on a seasonal scale is a challenge, mostly because there is no recent historical precedent for such change in the climate system.

Methodology & Theoretical Orientation: We forecasted monsoon using our recently developed methodology, which is based on the theory of critical transitions. Our predictions rely on observations of near-surface air temperature and relative humidity from both the ERA-40 and NCEP/NCAR re-analyses. We performed our forecasts for the onset and withdrawal of monsoon for the Central part of India.

Findings: It was revealed that climate change affects the Indian summer monsoon in two aspects: in the last decade, the intensity of monsoon rainfalls in the Central part of India has increased, and the onset and withdrawal of the monsoon have been delayed. This is due to an increase in spring temperatures and a slower cooling in autumn that is linked to global warming. The novel approach allows accounting climate change effects and predicting the monsoon onset and withdrawal dates for 40 and 70 days in advance, respectively. The results show that our method allows predicting the monsoon not only retrospectively, but also in the future: in 2016 and 2017 both of our forecasts were successful. Hence, we proved that such early prediction of the monsoon timing is possible even under the conditions of climate change.

Abstract:

Open burning of waste at dumpsites is considered to be the easiest mode for wastes disposal, but is also a source of evident pollution and threat for human and environmental health. Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/PCDFs, or dioxins/furans) are unwanted by-products of combustion processes. Dioxins belong to persistent environmental pollutants (POPs) and they arise concerns because of highly toxic potential. The known toxicity and persistence of some congeners in the environment has emphasized the necessity to assess releases of those supertoxicants at open burning of wastes in some areas of Armenia. Dioxins formation upon wastes burning depends on composition and combustion conditions. In order to identify characteristics and strength of emission sources of POPs from wastes open burning in different marzes (provinces) of Armenia and to calculate dioxins emissions to air and soil UNEP methodological guidance was used. To quantify emissions the ''emission factor'' describing dioxins and furans entry into environment/media per unit of activity was used, such as toxic equivalent quotient (TEQ). TEQ indicates the potential toxicity of the particular substance itself as related to the most powerful poison among all dioxins—2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD). The sum of emission factors allows estimation of the total “dioxin” toxicity of the given source. The key research findings were as follows: emissions in air varied from 1.749 gTEQ/year (Ararat marz) to 9.382 gTEQ/year (Shirak marz), while emissions on land ranged from 0.061 gTEQ/year (Armavir marz) to 0.3128 gTEQ/year. Hence, efforts are required to reduce the current exposure.

Title: On aerosol-chemistry-cloud-climate interactions and entanglements
Biography:

Abstract:

Aerosols and chemically reactive gases have important impacts on regional and global air quality and climate change. Despite decades of efforts, the model simulations of aerosols, chemically reactive gases and clouds are still uncertain due to the complex conundrum of aerosol-chemistry-cloud-climate interactions. The complicated entanglements and feedbacks among those atmospheric elements lead to a difficult and painstaking task for reducing the uncertainties in the future air quality and climate predictions. Nevertheless, the increasing demands for the accurate future air quality and climate information with high resolution require the high performance of multi-scale modelling. The Aerosol Chemistry Model Intercomparison Project (AerChemMIP) provides us a good opportunity to quantify the air quality and climate impacts of aerosols and chemically reactive gases. The project is designed to reduce the uncertainties in emissions, atmospheric compositions, radiative forcing and climate feedbacks, and improve the capabilities of model predictions. The outcomes of global model simulations will also be a benefit to improving the regional model simulations using the downscaling technique. With the amazing progress from ground-based, airborne and space-based measurements, we advocate an approach of integrating modelling and observation for model process studies, model validations and data assimilation. More in situ measurements and model improvements are necessary to better predict future air quality and climate change on multiple temporal and spatial scales.

Biography:

Glen Gawarkiewicz is a Physical Oceanographer at the Woods Hole Oceanographic Institution. His research focuses on shelfbreak processes and the exchange of water masses between the continental shelf and the deep ocean. He has been involved in the planning and scientific direction for the Ocean Observatories Initiative, Pioneer Array. He works closely with the Commercial Fisheries Research Foundation of Rhode Island on collaborative research.

 

Abstract:

Statement of the Problem: The continental shelf and slope region of the Northeastern United States is rapidly warming (. Record warming of the continental shelf occurred in 2012 due to a northward shift in the atmospheric jet stream during winter and a corresponding reduction in heat loss from the ocean in winter. Warming of the continental shelf occurs from both atmospheric effects as well as ocean advection.  How have oceanographic processes changed over the past ten years?

Methodology & Theoretical Orientation: A recent ocean observatory, the Ocean Observatories Initiative, Pioneer Array, is providing new data and insights into continental shelf and slope processes of New England. It has been in operation since 2014. In addition, a cooperative research program, the Commercial Fisheries Research Foundation/Woods Hole Oceanographic Institution, Shelf Research Fleet is providing vertical profiles of temperature and salinity across the continental shelf south of New England since November 2014.

Findings: Data from both the Pioneer Array and Shelf Research Fleet show that there have been significant exchange events at the shelfbreak (edge of continental shelf) in which waters of Gulf Stream origin are carried considerable distances across the continental shelf. A particularly dramatic event in December 2016/January 2017 resulted in a warm temperature anomaly of over 5°C, lasting over a month across most of the continental shelf. Several other significant ring intrusion events have been observed since 2014.

Conclusion & Significance: The ring intrusion event led to significant ecological effects, including the presence of warm water species over the continental shelf in January 2017. Further work is necessary to understand Gulf Stream motions and their impact on the continental shelf south of New England (Andres 2016).

Title: International cooperation for DPRK’s environmental restoration
Biography:

Hyun-Ah Choi has completed her PhD from Korea University. She is currently a Reseacher at Hanns Seidel Foundation in Republic of Korea, based in Seoul, consulting NGOs, academic and public institutions in questions of unification and inter-Korean environment cooperation. She also works on sustainable development issues in the inner-Korean border area and from 2015 participates the survey as an Expert. Her research interests include international environment cooperation and ecosytem services assessment. Her publications include reserah articles in international journals like Journal of Forestry Research, Sustaniablity, Advances in Space Research and Journal of Plant Biology.

 

Abstract:

The Democratic People’s Republic of Korea (DPRK) lacks both technical capacity and knowledge to survey environmental problems. Recently, the DPRK has been opening to certain international environmental issues such as biodiversity, wetland protection, sustainable forest management, and agroforestry. In this study, we analysed recent DPRK’s international environmental cooperation for developing technical capacity. DPRK started projects with various international organisations including Centre for Agriculture and Bioscience International for building plant protection capacity, Swiss Agency for Development and Cooperation (SDC) in collaboration with World Agroforestry Centre in China for sloping land management and agroforestry, International Federation of Organic Agriculture Movements for building capacity for organic agriculture development and Hanns Seidel Foundation (HSF) for improvement of rural living conditions through healthy forests and biodiversity. The international cooperation projects have been successfully introduced in model sites throughout several provinces of DPRK. It also increases the political support and concern of the DPRK government. Especially, HSF’s model site, Daedong-Gun, South Pyongan province in DPRK shows that the forest area in 2017 was increased and reduced their rate of loss, while in DPRK, severe forest fires have exacerbated the loss of forest. It appears the model site has a great possibility to prevent deforestation at local level. However, large scale restoration is required to restore the degraded land and environment in DPRK. To implement it on a larger scale, cooperation with international organizations and non-governmental organizations would be necessary.

Sara E Alexander, as an Applied Environmental Anthropologist, the majority of her research projects focus on the dynamics of human populations and environmental change, specifically climate change in most cases. A project she recently completed in several coastal communities in Belize, addresses the ways in which households respond to climate-related shocks. The research involved determining levels of vulnerability and devising a Resilience Index to examine specific responses and coping strategies to climate-related disturbances. In 2014, she conducted research in the western interior region of Belize to determine awareness and level of understanding of climate change on the part of those working in the tourism industry.

Abstract:

We live in a world of climate uncertainty where farmers pursue a variety of means to diminish vulnerability, utilizing strategies to respond to and mitigate against the effects of climate change. Specific responses include seeking new knowledge and training, using particular agricultural technologies, relying on institutional resources, and turning to both personal and professional social networks. The traditional model of agriculture as “performance”, ultimately affirms that risks, such as challenges associated with climate change, are entrenched within a structure of social, economic and biophysical mechanisms that are continuously being managed by farmers. Agricultural systems are correspondingly found in a setting of commonly-shared worldviews, social complexities, values, and cultural norms. In this landscape, the decisions farmers reach, entail meaning and direction that may be far more complex than an analysis focused solely on the more pragmatic economic principles and agricultural productivity standards. Rather, they comprise the farmer’s intuitive reasoning and socialization in addition to his/her technical and resource management skills. The author will present findings from an ethnographic pilot study aimed to illuminate farmers’ perspectives on changing weather patterns, climate change forecasts and their implications for viability of farming enterprises, all within the context of Texas wheat production. With focus on livelihoods and cultural values, risk management, and weather and climate change in terms of decision-making and wheat farming in west Texas, the study emphasizes what motivates farmers and how they themselves value those factors that contribute to their goals and aspirations, how farmers see themselves addressing climate risk in the context of a wide array of pressures, and how farmers respond to the communication of predictive information in light of their sense of place and self.

He has published in all the top journals in Development and Environment, including Journal of Development Economics, Journal of Environmental Economics and Management, World Development, Ecological Economics and Land Use Policy, Agricultural Economics, and Environmental and Resource Economics.

 

Abstract:

Managing increasingly scarce irrigation water has become a major challenge to many countries in the face of changing climate and a rising population all over the world. United Nations’ Sustainable Development Goal 6 emphasizes ensuring availability and sustainable water management. Target 6.4 emphasizes increasing water-use efficiency across all sectors and sustainable withdrawals and supply of freshwater to address water scarcity. Bangladesh government has incorporated the SDGs in its Seventh Five Year Plan (2016–2020) in which north western Bangladesh was identified as water scarce or drought-prone area. This is one of the three most climate vulnerable zones of the country that receives least rainfall and suffers from severe ground and surface water scarcity. Against this background, using farm-level survey data from rice growers and a probit model, this study aims to assess the economic effects of the use of alternative wetting and drying (AWD), a water saving technology, in Naogaon district of Bangladesh. Findings suggest that the use of AWD saves water, decreases production cost through reduced irrigation cost, and raises net benefit/gain significantly without reducing total rice production. Major policy implications include information dissemination about the use and benefit of AWD through farmers’ training/workshops or through farm-level agricultural officers. Agricultural officers should also encourage farmers to use a recently developed method named “dry direct seeded technology” that has the potential to save 60% irrigation water for irrigated rice in the dry season.

Abstract:

A series of propositions are developed for controlling the carbon cycle by changing the way that we dispose our wastes. By defining contemporary biological carbon as neutral, fossil carbon as positive, and biochar as negative, an ideological framework can be easily developed for the creation of carbon negative societies. The capitalism vs. communism debate is revisited, but neither system addresses the waste problem, “linearity”, the nature of money nor the need for sustainability or even what to do with waste (mostly carbon-based) which normally ends up in the air, water or landfill. Economics, as a mechanism for evaluating the movement of goods and services throughout society, in terms of energy expenditure and waste generation on a cyclical basis is a relatively unexplored field. Waste can be defined as associated with a negative cost and economic entropy. Entropy can be reversed by inputting energy into a system. A range of potential analogies for the development of global carbon neutrality can be discussed. These include cellular biology and ecology as viewpoints for generation of ATP (used as the currency of any cell, whether autotrophic or heterotrophic). For human society (a superorganism based on many municipal “cells”) the development of a currency based on the “species” of alternative (electrical) energy, would be analogous to ATP. King Darius, used water dockets as currency in desert oases. By also referencing successful, premodern, economies, it may be possible to build an “alternative economy” based on wasteland, wastewater, waste-derived energy, wasted energy, etc., and most importantly, wasted people. This “second tier” economy would depend on the waste stream from the existing economy for its manufacturing, building materials, fertilizer, etc. and hence would complement the existing economy. Application of these simple ideas might also be appropriate in the building of a lunar base.

Abstract:

Forest fires are a global environmental problem that burn millions of hectares every year throughout the planet, causing human and economic losses as well as significant degradation of the natural environment. In Southern Europe, with Spain and Portugal at the head, 70% of the continent's forest fires occur. The growing human population and continuous occupation of the territory, exercise a role of domination and submission of nature. For this and other reasons, we can’t omit the involvement of humans in the probability of occurrence of fires in the world. At present, it seems obvious that we are experiencing a change of trend in aspects such as temperature and precipitation rates, something that, together with other environmental evidences, has been associated with global climate change. In this context and as it always did, fire plays a modulating role in the characteristics of the vegetation and the structure of the landscape. This last aspect is the one we focus on in this study. Some of our findings determine that 95.90%, of the Spanish population surveyed, consider that there is a representative and characteristic landscape in the area where they live. We have also found that the "recreational" value of landscape is greater than the "economic" value, an aspect that may be relevant when it comes to forest management and forest fires. On the other hand, we have been able to confirm the high concern of Spanish citizens for the threat posed by natural phenomena to the landscape of their community and, especially, the concern about the threat of forest fires on the landscape, where 80.34% of our sample has identified damage to the landscape due to the impact of forest fires. Studies on social perception are a good tool for planning and improving prevention and risk management, as well as for the development of environmental policies appropriate to each specific territory.

Abstract:

Indonesia is the largest archipelago in the world. Its coastline is about 95.181 km with a sea area of 5.4 million km2. Indonesia has 1.2 million hectares (ha) of brackish water pond area, but only 37.5% of them are used for aquaculture activities. However, marine culture area is only used about 2% from the 4.5 million ha that is available. The low utilization of brackish water pond and marine culture area are generally caused by environmental damage due to the excessive exploitation by intensive aquaculture activities during the period of 1980s and climate change that caused sea level rise in the coastal area. In line with the growth of global paradigm in the face of the environmental and climate change as response to the global warming, it is time for Indonesia to implement the concept of management and utilization of natural resources, taking into account the balance and stability of the natural resources and the environment, such as in the concept of Sato-Umi.  The integrated multi thropic aquaculture (IMTA) on the bases of bio-recycle system and Sato-Umi concept should be applied for sustainable aquaculture. An experiment of the IMTA in the brackish water pond as a closed system model (CSIMTA) has shown good performance in the production of multi species fisheries commodities as well as water quality stability. In the onshore area, developing of open system model of IMTA (OSIMTA) by combining seaweed culture and floating cage of multi species fisheries commodities also seem to have a good prospective to improve productivity of coastal area.  In the future, developing aquaculture models using the bio-recycle system to reduce and minimize the inorganic and organic waste from the remaining feed, faeces and the other sources will be useful to maintain sustainable aquaculture in the coastal area.

Abstract:

Climate change poses serious energy, water and health challenges for the United Arab Emirates (UAE). While closely interconnected, the development of sustainable energy, water and health policies has typically been viewed as independent, sector-specific planning challenges. However, changing demographics, a rapidly growing economy, increasing reliance on desalination, and worsening air quality—all taking place as climate change unfolds— suggest a need for a more integrated approach to risk management. Accounting for the interactions between an “energy-water-health nexus” is one way to ensure that development strategies are considered within a framework that addresses the range of potential tradeoffs, risks, and synergies. To address the energy-water-health nexus under a changing climate, research activities were undertaken as part of the Local, National, and Regional, Climate Change Programme (LNRCCP) of the Abu Dhabi Global Environmental Data Initiative (AGEDI). Climate change modeling at the regional spatial scale (Arabian Peninsula; Arabian Gulf) was first carried out to establish the atmospheric and marine physical conditions that will underlie energy, water, and health challenges in the future. The results of this modeling were then used as inputs to an analysis of policies that aim to account for the linkages across the energy-water nexus in one hand and the energy-health nexus on the other. The results show that climate change will render an extreme hyper-arid climate even more so, while the waters of the Arabian Gulf will experience heightened salinity, changing circulation patterns, and higher temperatures under intensifying desalination activities. The analysis of the energy-water nexus shows that a range of water/energy efficiency and renewable energy measures can lead to significant reductions in energy use and annual greenhouse gas emissions, while coming at negative societal cost. The analysis of the energy-health nexus shows that the gradual introduction of energy efficiency and renewable energy measures can lead to substantial decreases in premature mortality and health care facility visits in urban areas.

Biography:

Pavel Kishcha graduated from Lomonosov Moscow State University in 1979 with an MSc in Physics, and received PhD in Geophysics from the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN), Russian Academy of Sciences, Moscow, in 1985. Currently, he is a Senior Research Scientist at the Porter School of Environment and Earth Sciences of Tel-Aviv University (TAU). His research interests include investigation of heating in the uppermost layer of the Dead Sea and long-term trends in Dead Sea surface temperature based on satellite measurements; aerosol physics and aerosol numerical modeling in the atmosphere; aerosol spatial distributions and trends based on satellite and ground-based aerosol measurements. He has been producing daily operational numerical predictions of desert dust storms over the Sahara desert and adjacent regions since 2006. He is the Author of over 50 peer-reviewed publications.

Abstract:

Statement of the Problem: The coastal area of the hypersaline terminal lake of the Dead Sea is a unique area of dry land of the lowest elevation on Earth (-420 m a.s.l.). The Dead Sea has been drying up over the last four decades: the water level has dropped at the rate of approximately 1 m year-1. The Dead Sea drying up is due to climate change in the Eastern Mediterranean, which is expressed by the lack of water inflow from the Jordan River, a decreasing tendency in rainfall over the last 40 years and increasing evaporation. Climate change in the Eastern Mediterranean is accompanied by a positive feedback loop between the shrinking of the Dead Sea and the increasing trend in Dead Sea surface temperature (SST) of 0.6°C per decade. This causes increasing evaporation and the continuing disappearance of the Dead Sea.

Methodology & Theoretical Orientation: To estimate the effect of climate change in the Eastern Mediterranean on the Dead Sea, we analyzed yearly data of Dead Sea water levels based on available measurements from 1992 until the present. Several factors could influence the observed Dead Sea water level drop, such as long-term changes in evaporation, in SST, in solar radiation and in near-surface wind. To estimate long-term trends in SST, satellite MODIS data were used.

Conclusion & Significance: We found that there is a positive feedback loop between Dead Sea shrinking and increasing SST. Additional heating of Dead Sea surface water (as a result of Dead Sea shrinking) is leading to an increase in water evaporation, consequently, to some additional decrease in Dead Sea water levels, eventually to subsequent shrinking of the Dead Sea water area. This positive feedback loop leads to acceleration in the Dead Sea water level drop causing a continuing hazard to this hypersaline lake.
