Authors: Cárdenas-Contreras German Enrique
Published: November 2021

En el panorama mundial, las Tecnologías de Información y Comunicación (TIC), forman parte de la política educativa en los países, sobre todo los más avanzados. El presente artículo tuvo como propósito determinar la influencia que han tenido las tecnologías educativas, en los procesos de enseñanza de finanzas internacionales en estudiantes universitarios. El proceso realizado desde una visión pedagógica se fundamentó, desde los cimientos teóricos del conectivismo, el cual explica el aprendizaje complejo en un mundo social digital en rápida evolución. La estructura metodológica se orientó desde un enfoque cualitativo de corte documental, con un tipo descriptivo; para la recolección de información, se utilizó como instrumento, una ficha de registro bibliográfico, en donde mediante un procedimiento de revisión documental, se recopilaron y analizaron seis experiencias exitosas relacionadas al ámbito de las finanzas y ciencias económicas, tanto en el contexto internacional, como a nivel nacional. Los resultados obtenidos, dieron muestra de que las TIC han tenido un impacto significativo, llegando a presentar un crecimiento exponencial en los contextos educativos, situación que llevó a que la dinámica entre docentes y estudiantes estuviera mediada por tecnologías, sin embargo, en el ámbito financiero existe poca cantidad de experiencias exitosas que reflejen el impacto de las tecnologías, hecho que evidencia falencias pedagógicas en los docentes de economía, siendo indispensable fomentar el uso de herramientas TIC y recursos digitales en sus prácticas pedagógicas.
Numerical Analysis of Natural Convection Heat Transfer Inside an Inverted T-Shaped Cavity Filled with Nanofluid
Authors: Sen Gopal , Inam Mohammad Ilias
Published: November 2021

This assessment is centered on the characteristics of natural convection heat transfer of Aluminium Oxide-Air nanofluid inside an inverted T-shaped enclosure with differentially heated sidewalls. The left edges of the enclosed cavity have been treated as a heated wall and are kept at a constant temperature. The right edges are also maintained at a constant temperature but lower than the heated wall. The top and bottom faces of the cavity have been considered adiabatic. The evaluation has been numerically investigated using ANSYS fluent. The effect of different significant parameters like volume fraction of nanoparticles, the shape of the enclosure, and Rayleigh number on the heat transfer characteristics inside an inverted T shape enclosure have been investigated. In this numerical analysis, a series of DNS simulations have been conducted for different Rayleigh numbers in the range of 103 to 106, the volume fraction of particles in the range 0≤ φ ≤0.1, and for the different aspect ratios for the inverted T shape have been conducted. The outcomes of this CFD analysis indicate a remarkable rise in the average heat transfer coefficient with the rising volume fraction of Al2O3 particles in the air. An increase of the average Nusselt number was also observed with the increase of Rayleigh number, but it drops slightly at a higher volume fraction of nanoparticles due to an increase in conductive heat transfer. For Rayleigh numbers ≥ 104, both the average Nusselt number and average heat transfer coefficient decrease up to a certain shape of the cavity aspect ratio. After that cavity aspect ratio, both the parameters value increase. But in the case of Rayleigh number = 103, both of the values decrease with the increase in the cavity aspect ratio.

Yacht Industry is one of the important and developing sectors and yacht furniture manufactory is a branch of this sector those are growing day by day. Important that yacht and yacht furniture are both as status symbols and integrate each other. Seeing yachts and furniture as status symbols is important for these two complementary sectors. This importance is even more significant as yacht furniture manufacturing is the second largest cost item in yacht building after engine equipment.Yacht furniture manufactoring has important position in the yacht industry, in the future this importance will be understood better. It is significant to make researches on yacht furniture manufactoring’s technology use, quality, institutionalization, efficiency, employment, added value, branding and design will help to develop and improve our economy. When The Turkish Yacht Furniture Sector is compared to its competitors it has a cheap but qualified workforce and a central location close to all markets. Using results obtained from this study; although companies mostly solve their design and production drawings with architects and engineers in their own design offices, the most important problem is production managment and planning. Also the most crucial problem about production side is that qualified workers do not have sufficient skills. For those problems, the sector should be introduced correctly and yacht educational schools should be increased. In our country, yacht furniture sector which is sub-sector under the yacht building industy that is dynamicly developing in last decate despite the contraction in developed countries.
INITIAL EVALUATIONS OF NATURAL ( 226Ra, 232Th and 40K) AND ARTIFICIAL ( 137Cs) RADIOACTIVITY OF ESKIKÖY MINERALIZATION AREA (GÜMÜŞHANE, TÜRKIYE)
Authors: VURAL Alaaddin , KAYA Ali
Published: November 2021

Within the scope of this study, the natural (226Ra, 232Th and 40K) and artificial (137Cs) radioactivity concentrations of the Eskiköy Mine area within the borders of Gümüşhane, which is located in an important metallogenic belt of Turkey, were investigated. In order to determine the natural and artificial radioactivity of the field soils developed due to mineralization, hydrothermal alteration and weathering, 12 soil samples were taken and activity concentrations of 232Th, 226Ra, 40K and 137Cs radio isotopes were measured with a gamma detector. It was observed that the 40K natural radio isotope activities of the area mostly exceeded the weighted world average, and the 232Th, and 226Ra natural radio isotope activities exceeded the weighted world averages at 5 of the 12 sampling points. It was determined that the artificial 137Cs activity concentrations in the area were above the detection limit at 9 sampling points and above 3 Bq/kg at 8 sampling points. It has been evaluated that the high 137Cs activities detected in the Eskiköy mine area are due to the Chernobyl nuclear power plant accident and similar anthropogenic effects. The mine area was also evaluated in terms of radiation risk in the context of medical geology, with parameters of radiological hazard indices, radium conjugate activity value, absorbed dose rate and annual effective dose rate, and remarkable findings were obtained. When all these findings of the study area are evaluated together, it has been concluded that the Eskiköy mining area should be studied in more detail in terms of natural and artificial radioisotope activity concentrations and their effects on human health.
THERMAL PARAMETERS AND STRUCTURAL INVESTIGATIONS OF Cu-BASED SHAPE MEMORY ALLOYS IRRADIATED WITH Co-60
Authors: Nevin BALO Şahide , ORHAN Abdulvahap
Published: November 2021

Gamma radiation is a type of radiation that can change the structural properties of materials. Many physical and structural properties of metals and alloys change due to defects in their crystal structures in response to irradiation. Shape memory alloys (SMAs) are functional materials and are used in mechanical devices for monitoring nuclear facilities. In this study, copper-based SMAs were used. Copper-based SMAs are very sensitive to alloying elements and small changes in element percentages. Cu-11.6Al-0.42Be, Cu-11.8Al-0.47Be, Cu-13Al-4Ni, and Cu-13.5Al-4Ni (wt%) SMA samples were irradiated with a fixed radiation dose of 50 kGy. The effect of irradiation on the thermodynamic parameters and structural properties of copper-based SMAs was investigated. The effects of irradiation on thermodynamic parameters were determined by differential scanning calorimetry (DSC). Structural examinations were made by X-ray diffraction (XRD) and optical microscope observations. Microhardness measurements were taken. The results obtained for Cu-based SMAs were evaluated both as homogeneous and irradiated samples and according to alloying elements.
Y–Z IN THE LABOUR MARKET: EMPLOYEE PERCEPTIONS IN DIFFERENT CULTURES (HUNGARY–PAKISTAN)
Authors: Bencsik Andrea , Shujahat Ali , Juhász Tímea
Published: November 2021

Research on generations examine and analyse the similarities and differences between various age groups, and their opportunities for cooperation in the labour market, from various perspectives. According to the research, the behaviour and preparedness of each generation are different, the coordination and proper management of which poses challenges for all organisations. This is especially true when staff from national cultures with very distant values work together. The recognition of this problem was the pretext to the present research. The aim of the research is to examine the perception of the under 30 age group socialised and employed in two largely different cultures (Hungarian–Pakistani). Contrary to our assumption, the results of the quantitative research based on an online questionnaire confirm that the respondents do not perceive differently the behaviour, attitudes, expectations regarding work, workplace and employers of Pakistani and Hungarian young people at work. Employers’ perceptions of this age group play a significant role in choosing the tools that affect their retention in the workplace. In this respect, the employees of the studied cultures find similar solutions expedient.
THE SEARCH FOR TIME-SERIES PREDICTABILITY-BASED ANOMALIES
Authors: Ospina-Holguín Javier Humberto , Padilla-Ospina Ana Milena
Published: November 2021

This paper introduces a new algorithm for exploiting time-series predictability-based patterns to obtain an abnormal return, or alpha, with respect to a given benchmark asset pricing model. The algorithm proposes a deterministic daily market timing strategy that decides between being fully invested in a risky asset or in a risk-free asset, with the trading rule represented by a parametric perceptron. The optimal parameters are sought in-sample via differential evolution to directly maximize the alpha. Successively using two modern asset pricing models and two different portfolio weighting schemes, the algorithm was able to discover an undocumented anomaly in the United States stock market cross-section, both out-of-sample and using small transaction costs. The new algorithm represents a simple and flexible alternative to technical analysis and forecast-based trading rules, neither of which necessarily maximizes the alpha. This new algorithm was inspired by recent insights into representing reinforcement learning as evolutionary computation.
Integrated Clinical Pathways: Communication and Participation in a Multidisciplinary Team
Authors: Šimec Mateja , Krsnik Sabina , Erjavec Karmen
Published: November 2021

BACKGROUND: An integrated clinical pathway (ICP) is a key method for structuring or planning processes of care, enabling the modernization of health-care delivery and coordination of multiple roles, forming a complete, patient-centered multidisciplinary health-care team and establishing the sequence of activities, promoting individual and team communication, collaboration, networking, and transparency, and reducing the cost of care.

AIM: As there is a research gap in the area of communication among members of a multidisciplinary team for the treatment of patients through an ICP, the aim of this study was to determine the impact of communication of a member of a multidisciplinary team on the active participation of an individual in this multidisciplinary team.

METHODS: A cross-sectional study of three ICPs, forchronic kidney disease, stroke, and total hip arthroplasty was conducted in a typical Slovenian general hospital.

RESULTS: The results show that in the analyzed hospital, two of the three clinical pathways are not yet fully integrated.

CONCLUSION: There is a weak influence of staff communication within a multidisciplinary team on an individual’s participation in this multidisciplinary team, indicating the need for various activities to actually implement clinical pathway “integration,” and promote better communication within teams to strengthen participation in multidisciplinary patient care pathways.

Published: November 2021

The family Microthyriaceae is represented by relatively few mycelial cultures and DNA sequences; as a result, the taxonomy and classification of this group of organisms remain poorly understood. During the investigation of the diversity of aquatic hyphomycetes from southern China, several isolates were collected. These isolates were cultured and sequenced and a BLAST search of its LSU sequences against data in GenBank revealed that the closest related taxa are in the genus Microthyrium. Phylogenetic analyses, based on the combined sequence data from the internal transcribed spacers (ITS) and the large subunit (LSU), revealed that these isolates represent eight new taxa in Microthyriaceae, including two new genera, Antidactylariagen. nov. and Isthmomycesgen. nov. and six new species, Antidactylaria minifimbriatasp. nov., Isthmomyces oxysporussp. nov., I. dissimilissp. nov., I. macrosporussp. nov., Triscelophorus anisopterioideussp. nov. and T. sinensissp. nov. These new taxa are described, illustrated for their morphologies and compared with similar taxa. In addition, two new combinations are proposed in this family.
Représentations sociales de la coopétition au niveau individuel. Le cas d’une alliance entre instituts de formation en ostéopathie
Authors: Albert-Cromarias Anne , Livertout Julien
Published: November 2021

Si la littérature sur la coopétition est désormais abondante, peu de travaux s’intéressent aux perceptions qu’en ont les collaborateurs eux-mêmes. En complément d’articles récents sur la capacité de coopétition et sur la perception intra-organisationnelle d’une telle stratégie, le présent article s’intéresse à sa représentation sociale par les collaborateurs, en amont d’un projet de coopétition entre organisations. A travers une étude de cas, nous étudions plus spécifiquement le rapprochement de trois instituts de formation en ostéopathie. Les représentations sociales y sont repérées à l’aide d’un questionnaire d’association sémantique d’une part et d’entretiens semi-directifs d’autre part, administrés auprès de collaborateurs appartenant à différents groupes professionnels. Les résultats montrent que les représentations sociales associées à la coopétition peuvent être tout à fait positives ; ils insistent sur l’importance de s’intéresser dès l’amont à la perception d’une telle stratégie par les collaborateurs. Notre recherche contribue ainsi à la littérature sur la coopétition sur deux aspects. Tout d’abord, en s’intéressant à l’amont de la coopétition, notre recherche apporte une contribution à la fois originale – car non encore explorée – et primordiale – puisqu’il s’agit d’anticiper le degré d’acceptabilité de la coopétition par les collaborateurs eux-mêmes. De plus, notre recherche aborde la perception de la coopétition au niveau individuel, encore très peu étudiée. Plusieurs recommandations sont ainsi formulées à destination des équipes de direction qui engagent des projets coopétitifs.
Is there a relationship between investor sentiment and green finance?
Authors: Mzoughi Hela , Hchaichi Rafla , Guesmi Khaled

En mettant en œuvre le vecteur modèle de correction d’erreur, nos résultats mettent en évidence un ajustement non significatif vers un équilibre de long terme entre le sentiment des investisseurs sur les marchés financiers et le soutien des projets verts. Notre étude vise à aider les investisseurs à dynamiser des portefeuilles respectueux de l’environnement et à ajuster leur stratégie d’investissement en fonction des indices de sentiment.
Exploring the nexus between green finance, innovation, clean energy and oil
Authors: Ghorbal Sana , Belaïd Fateh
Published: November 2021

Cet article vise à explorer la relation entre les obligations vertes, l’innovation, les énergies propres et le pétrole. Il utilise des indices s’étendant de juillet 2014 à juin 2021. Les approches ARDL (Autoregressive distributed lag) et VECM (Vector Error Correction Model) ont été utilisées. Les estimations de l’élasticité à long terme révèlent que l’innovation et l’énergie propre affectent positivement les obligations vertes. Dans le même temps, l’augmentation du pétrole entraîne une diminution des obligations vertes. Il existe des causalités bidirectionnelles à long terme entre les obligations vertes, les énergies propres et le pétrole. Les résultats de la causalité de Granger à court terme montrent une causalité bidirectionnelle entre les obligations vertes et l’innovation, des causalités unidirectionnelles allant du pétrole à toutes les autres variables, et une causalité unidirectionnelle allant des obligations vertes aux énergies propres. Les politiques de financement vert sont essentielles pour renforcer le développement vert. Les gouvernements doivent donc adopter des politiques qui encouragent l’innovation verte et la financent. De même, les sources d’énergie basées sur les émissions doivent être remplacées par des sources renouvelables afin de limiter la détérioration de l’environnement.

Published: November 2021

La Communauté Nova Esperança s'est implantée en 2020 dans un espace public à la périphérie de la ville de Curitiba, capitale de l'état de Paraná, à partir des actions du Mouvement Populaire pour le Logement (MPL). La zone occupée, dont la superficie totale est de 371 420,23 m2, appartient à la Fondation d'Action Sociale, une entité publique liée à l'exécutif municipal de la ville de Curitiba. S’agissant d’une occupation, la zone est actuellement l'objet de l'action légale de reprise de possession. Face à la nécessité d'éclaircir les caractéristiques de la zone, le Parquet de l'état du Paraná a demandé à l'Université Fédérale du Paraná (UFPR) une étude technique sur les possibilités d'utilisation, d'occupation et de lotissement de la zone ainsi que sur les contraintes environnementales puisque la zone est située dans une commune d’environnement fragile. Dans cette étude, nous analysons l’environnement, les conditions générales de vie, de logement et les formes de génération de revenus d’environ 1 200 familles dont 65 % ont entre 25 et 59 ans et dont ¼ sont des immigrés particulièrement touchés par la pandémie et par la crise économique. Dans l’ensemble, nous avons identifié l'omission de l'État à l'égard des politiques de logement et de protection sociale. Dans le sens inverse, dans la communauté, les habitants préservant la forêt, organisent la collecte des déchets solides, construisent des bio digesteurs et certaines structures de bio-fosses dans le but de réduire la contamination des sols et des eaux souterraines. En outre, il y a le jardin communautaire, la cuisine collective et l’atelier de couture. La zone occupée est solution évidente au déficit de logements. En outre, la génération de revenus et les nouvelles formes de sociabilité entre brésiliens et immigrés sont des exemples qui peuvent inspirer la mise en place des politiques d’accueil et d’intégration.

O presente artigo tem por objetivo apresentar, cartográfica e textualmente, aspectos ligados aos Jogos Olímpicos de Verão (Tokyo 2020), vistos com um viés geográfico e, até certo ponto, também geopolítico (vide a participação das “3 Chinas”, que chamou a atenção para disputas econômicas, diplomáticas e nacionais em jogo).Salientamos e problematizamos certos aspectos passíveis de análises regionais e que transpassam os limites dos esportes, podendo passar facilmente desapercebidos por parte grande do público que assistiu ao megaevento.A proposta visou dar igual ênfase (pesos iguais) para a linguagem visual cartográfica e a linguagem textual analítica. Utilizamos duas fontes básicas de informações: o International Olympic Committee (IOC) e o United Nations Development Programme (UNDP).Analisamos o desempenho de cada país (delegações) no que se refere à 1) pontuação geral obtida; 2) comparação com seu desempenho anterior (Rio 2016); 3) relação entre o número de medalhas e o número de atletas enviados; 4) relação entre o número de medalhas e o total populacional e 5) relação entre a obtenção da pontos olímpicos e o respectivo IDH (Índice de Desenvolvimento Humano).Concluímos que o acesso à maior riqueza material (e imaterial) em disputa, simbolizada pela medalha ouro olímpica, distribui-se espacialmente pelo globo terrestre de modo concentrado (Mapa 1), hermético (Mapa 2), competitivo (Mapa 4), desigual (Mapa 5) e injusto (Mapa 6).

Published: November 2021

O presente artigo objetiva analisar a distribuição de óbitos por COVID-19 nos municípios brasileiros e a relação desta com aspectos socioeconômicos (renda) até a data de 14 de julho de 2020. A metodologia esteve pautada na verificação de autocorrelação espacial com base no Índice Global de Moran e no Índice Local de Moran (LISA) em suas formas univariada e bivariada. A forma univariada foi utilizada para investigação da distribuição da Taxa de Mortalidade por COVID-19 (TMC), enquanto que a forma bivariada foi utilizada para verificação de autocorrelação espacial entre as variáveis TMC (variável dependente) e IDHM Renda (variável independente) nos municípios brasileiros até a data de 14 de julho de 2020. Os resultados evidenciaram a presença de clusters formados a partir de agrupamentos de municípios com altos valores de TMC, sobretudo nas regiões Norte e Nordeste do Brasil. Além disso, foi constatada autocorrelação negativa entre as variáveis TMC e IDHM Renda, com destaque para grandes porções territoriais das regiões Norte e Nordeste setentrional. A quantidade de casos de COVID-19 em uma determinada área geográfica e a renda de sua população são fatores essenciais para a compreensão da distribuição dos óbitos relacionados a essa doença.

Published: November 2021

No Brasil, a região Nordeste é altamente vulnerável às mudanças climáticas em virtude de seus baixos índices de desenvolvimento socioeconômico. Partindo desse pressuposto, objetivamos investigar como as capitais do Nordeste brasileiro têm internalizado a questão climática em suas agendas governamentais locais, identificando e analisando as iniciativas direcionadas ao enfrentamento das mudanças climáticas no âmbito local. Para isso, ancorados numa metodologia de caráter qualitativo, fazemos uso de levantamento bibliográfico, bem como análise de documentos e notícias jornalísticas, analisados a partir da técnica de análise de conteúdo. A partir da análise e discussão dos resultados, identificamos uma ineficiência governamental face ao desafio das mudanças climáticas no contexto das capitais do Nordeste do Brasil. Em síntese, concluímos que as questões climáticas são internalizadas e efetivadas em níveis diferentes nas agendas governamentais das cidades analisadas, com a maioria delas apresentando baixa incorporação.

Published: November 2021

À Belo Horizonte, capitale du Minas Gerais, comme dans de nombreuses villes brésiliennes, avec la croissance démographique l’environnement “naturel” a été profondément modifié. Parallèlement à cela, au sud de la ville l'activité minière s’est développée dans la Serra do Curral qui renferme l'un des plus grands gisements de fer du Brésil. Classée pour son paysage, la Serra constitue une référence géographique pour toute la zone métropolitaine, un symbole historique, naturel et paysager de Belo Horizonte. Dans cet environnement de carte postale, se sont développés de riches quartiers mais aussi, contrastant avec ce voisinage, une petite favela appelée le « bout du monde » (Acaba Mundo), comptant parmi les quartiers les plus pauvres de Belo Horizonte et tirant une partie de ses ressources de sa proximité avec la nature. Mais ce secteur attire la spéculation immobilière. En réaction à ces attaques des mouvements se structurent et des stratégies s’élaborent autour de l’espace convoité. Dans ce conflit pour l’appropriation de la nature en ville, des alliances de circonstance se sont nouées face aux promoteurs entre les habitants de la favela et les résidents aisés des quartiers alentours, aux intérêts momentanément convergents, les richesses environnementales du secteur incitant les uns et les autres à revendiquer un droit à la ville. Dans cette lutte pour la justice spatiale dans un contexte de catastrophes écologiques récentes qui ont meurtri la région et fortement marqué l’opinion, les projets immobiliers irrespectueux des obligations écologiques et sociales se heurtent à un front citoyen, associatif et informé du droit environnemental.
Climate Change Information and Media
Authors: Neelima B. N.
Published: November 2021

Climate change is a scientific, health, political, economic, national security, environmental, moral and religious issue, among many others. The article presents the findings of a study which investigates what messages and messengers best engage young people with climate science and its solutions. The opinions and media habits of young adults, aged 18-25 currently residing and studying in two metropolises of India, Bengaluru (Bangalore) and Chennai (Madras) vis-à-vis climate change have been elicited and interpreted. A survey of 500 randomly selected college and university students studying and residing in these two metropolises have revealed a heightened concern for the global environment and climate change issues among youth. The extent of information the respondents had on climate change issues was considerable. The respondents relied more on social media, especially blogs and networking groups for information on climate change, than the traditional mass media. Gender, economic status, course of study, and parental education were some of the important variables strongly associated with knowledge about climate change issues.
Fulani Herdsmen and Farmers Conflicts in Nigeria
Authors: Dewan Andrew Danjuma
Published: November 2021

This chapter explores the media coverage of violent conflicts and climate change issues in Nigeria from the perspective of human rights journalism. Nigeria has had a chequered history of violent conflicts, especially since it achieved self-rule from Britain in 1960. These conflicts have been wide-ranging and cross-cutting (political, ethnic, religious, communal, among others). The Nigerian media have equally had a long history of the coverage of these violent eruptions across the country. However, the mainstream media's approach to the coverage of these issues have tended to be on the physical coverage of the conflicts to, almost, neglect of some of the underlying causative factors, such as climate change. The phenomenon of climate change globally is significant, especially in developing countries, such as Nigeria. In recent times, the threats that are posed by climate change have been enormous. Some communities across the country have been sacked by its devastations, especially from the norther corridors of the country. This has therefore necessitated the forced migration of some of these communities, especially the Fulani herdsmen and their cattle to other parts of the country for greener pasture. This situation always resulted in conflict, which is often violent. This chapter argues that, although the federal government of Nigeria through its Ministry of Environment have come out with programs and policies/initiatives aimed at combating the menace of this phenomenon, and the media, apart from the fact that they have not fully keyed into these programs to step them down for the audience, there is the urgent need for them to review their approaches toward the coverage of these conflicts. This chapter advocates a human-rights-journalism-based approach to the coverage of these conflicts because of its diagnostic approach, which gives a critical reflection of the experiences of the victims of human rights violations in all its ramifications.
Climate Change Effects, Adaptation, and Mitigation Techniques in Tropical Dry Forests
Authors: Hasnat G. N. Tanjina
Published: November 2021

Tropical dry forests is one of the most unique forest types. It differs from other tropical forests with its climatic behavior like a prominent dry period, little annual rainfall, and high evapotranspiration. Out of six global bioclimatic zones, the forests are distributed in four. Climate change is now the most challenging issue regarding the fate of tropical dry forests. A severe climatic change is estimated to occur between 2040 and 2069 that could drastically change the precipitation pattern, temperature, aridity, and distribution of biodiversity. It could alter the forest type permanently. With a large number of heat-tolerant species, tropical dry forests have a great potentiality to conservationists with the prediction of a large area that could attain the climatic condition favorable for extension of tropical dry forests. But many of the species of tropical dry forests could be extinct due to changing climate at the same time. Proper adaptation and mitigation techniques could minimize the severity of climate change effects.

Published: November 2021

WFE nexus is an important aspect in building sustainable economies. Water is used in food production while water supply and food processing require energy. Understanding the interrelationships of the nexus components is a growing interest for researchers and policymakers towards sustainable development. This chapter analyses the in-depth meaning of the WFE nexus, its importance, and its involved processes. The chapter also evaluates the effects of climate change on the nexus using case examples in South Africa. It also proposes a road map to facilitate better management of the nexus by recommending useful action plans. These action plans prioritize on baseline data collection, optimization of WFE nexus processes and cooperative management of resources, and climate change adaptation.
Effects of Climate Change and Anthropogenic Activities on Algivorous Cichlid Fish in Lake Tanganyika
Authors: Munubi Renalda N. , Lamtane Hieromin A.
Published: November 2021

Over the last century, water temperatures in Lake Tanganyika have risen due to climate change, which increased thermal stratification and reduced the magnitude of nutrient availability. A rise in temperature increases the C:N:P ratio resulting in a poor algal diet. In addition, lake littoral habitat is experiencing increased sediment load due to deforestation of the watershed caused by anthropogenic activities. Sediments cover benthic algae and reduce its nutritional value, consequently affecting the foraging behavior, distribution, and growth performance of algivorous fish. Algae and algivorous fish are an important link in the lake food chain; therefore, if the rise in temperature will continue as predicted, then this may have a cascading effect for the rest of the community in the food chain including human being. This, in turn, may contribute to food insecurity at local and regional levels. To counteract this adaptation and mitigation measures such as environmental monitoring systems and creating new opportunities should be considered.
A Regional Model of Climate Change and Human Migration
Authors: Naugle Asmeret Bier , Backus George A. , Tidwell Vincent C. , Kistin-Keller Elizabeth , Villa Daniel L.
Published: November 2021

As climate change and human migration accelerate globally, decision-makers are seeking tools that can deepen their understanding of the complex nexus between climate change and human migration. These tools can help to identify populations under pressure to migrate, and to explore proactive policy options and adaptive measures. Given the complexity of factors influencing migration, this article presents a system dynamics-based model that couples migration decision making and behavior with the interacting dynamics of economy, labor, population, violence, governance, water, food, and disease. The regional model is applied here to the test case of migration within and beyond Mali. The study explores potential systems impacts of a range of proactive policy solutions and shows that improving the effectiveness of governance and increasing foreign aid to urban areas have the highest potential of those investigated to reduce the necessity to migrate in the face of climate change.
Climate Change Impacts on Biodiversity in Arid and Semi-Arid Areas

Published: November 2021

Considerable attention has been paid to climate change and its impacts on biodiversity. The climate change has caused several problems such as continuous ecosystem degradation and a resultant biodiversity decline. In addition, climate warming has a range of indirect effects through changes in vegetation type level and sea that affect physical and biological systems. This has also led to changes in the distribution of species, as well as reductions in the size of populations, or even local extinctions of these populations. Moreover, many species are disappearing with time due to climate change combined with the emergence of disease that develops and increases with time. These problems affect different biodiversity components that are close to collapse. This chapter explored the richness of biodiversity in arid and semi-arid zones. It is also illuminates the effects of climate change on distribution of biodiversity. The authors highlight the responses of biodiversity under climate change, in terms of species extinction, biodiversity loss, and the impacts of climate change to ecological tourism. Finally, the authors show how biodiversity can overcome the effect of climate change, by developing some systems that allow to them to survive and conservation of species and ecosystems.

Published: November 2021

Information communication technologies can only be beneficial to developing countries struggling to build adaptation capacity if technology adoption frameworks are tailored to suit their specific characteristics. The lack of timely, accurate, and reliable weather data and the increasing rate at which climate-related disasters are destroying lives and property in Uganda is evident of lack of good weather forecasts. The study set out to investigate the factors affecting ICT adoption and determine the technologies being used to respond to climate change effects. Specifically, the study set out the extent of use and the factors hindering or guiding ICT adoption. Factors hindering ICT adoption ranging from poor infrastructure to limited government support were established. The strategies that can be used to resolve challenges of ICT adoption, the major stakeholders, their responsibilities and how ICT adoption and utilisation can be enhanced to benefit other sectors of the economy is presented.

Climate change is a serious global issue and concern that is attributed to change. A change of climate that is directly or indirectly related to human activity, that which alters the composition of the global atmosphere and which in addition to natural climate variability observed over comparable time periods. There is therefore no doubt that the earth is warming, and the climate changing. Despotism and the rule of despots as agents of democracy has created a rift in the issue of climate change on its citizenry in the southern zone of Plateau State in the area of health, water shortages, cutting meals due to the economic recession in Nigeria. Research has shown that climate change can create a conflict, and it does have a direct effect on scarce resources required to sustain life. Water is at the heart of human existence. Global warming has a major impact on global water cycle, hence on rainfall, soil moisture, rivers, and sea levels. If climate change is not tackled urgently, the calamity will be enormous.
Mitigation of Climate Change Through Carbon Sequestration
Authors: Naik Alkesha , Roy Koushik Singha
Published: November 2021

Climate change is considered one of the burning issues and threats to the globe. One of the most important drivers of climate change is the increasing concentration of atmospheric greenhouse gases that trigger the altered climate patterns. Therefore, researchers are now tackling the adverse impact of climate change as well in minimizing the concentration and emissions of atmospheric greenhouse gases (i.e., carbon sequestration seems to be one of the most attractive choices for the researchers that could be useful for mitigating climate change conditions). The process deals with the capturing of atmospheric carbon dioxide (CO2) in various segments of natural ecosystems like soil, biological systems, oceans, thereby offsetting the adverse impact of climate change. In this review, the author examines the current scenario of carbon sequestration in the biosphere.
The Trinomial Food-Heritage-Education for Climate Emergency as a Tool for Territorial Innovation in the Euroregion of Eixo Atlântico

Published: November 2021

This chapter is dedicated to the food-heritage-education for climate emergency trinomial (FoHECE). It disseminates a study in the Euroregion of Eixo Atlântico. This Euroregion (Galicia, Spain and Northern Portugal) has been a victim of climate change (CC) due to drought. The project consisted of a participatory-action-research (PAR) with a set of environmental education facilities (EEF) that promote the connection local heritage-global reality. The main objective of the study was to help re-signifying activities in education for climate emergency based on dietary styles. Thus, a pedagogical activity was created with each facility, according to the PAR methodology, to sub-themes of the diet-CC binomial (e.g,. types of food consumed, origin, type of production, presentation) and to food aspects of each EEF surrounding. In addition to the state-of-the-art review on FoHECE, results are discussed, and recommendations are suggested for future approaches and adaptations of this methodology to other contexts.

Today, the international community agrees that climate change is one of the most important threats to the equilibrium of ecosystems. For its part, Morocco is not immune to this phenomenon because of climatic disturbances that the country has known for several years. Moroccan oases are among the most affected ecosystems by climate change, which has resulted in reduced yields of agricultural production, poverty, and deterioration of natural resources. The reports showed that in Morocco the area of palm groves has been significantly reduced during the last decades resulting from the upsurge of drought phenomena, soil salinity, and the spread of “Bayoud.” Therefore, the deterioration of the socio-economic and environmental importance of the date palm is well established. Aware of these issues, many actions have been initiated by the Moroccan government to preserve this ecosystem. The aim of this chapter is to provide an overview of how climate change affects different levels of oases ecosystem in Morocco and to propose sustainable strategies to limit degradation of this vulnerable area.
Climate Change and Livestock Fertility

Climate change is a global threat to livestock sector to so many species and ecosystem in different parts of the world. Climate change, heat stress, and nutritional stress are the major intriguing factors responsible for reduced fertility in farm animals in tropical countries. Heat and nutritional stresses affect the reproductive performance by decreasing the expression of estrous behavior, altering ovarian follicular development and hormonal profiles, compromising oocyte competence, and inhibiting embryonic development in livestock. Climate is changed by greenhouse gases that released into atmosphere through man-made activities. Livestock contribute 18% of the production of greenhouse gases itself and causes climate change including heat stress, which has direct and indirect impact on fertility of the animals as well as reduce milk production. Adaptation to climate change and lowering its negative effect by alteration of animal micro-environment using different essential technologies are the main mitigation strategies to recover heat stress damage in this respect.
Climate Change and Crop Production in Africa
Authors: Amare Zerihun Yohannes
Published: November 2021

Agriculture, particularly crop production, is an economic activity that is highly dependent upon weather and climate in order to produce the food and fiber necessary to sustain human life. The vulnerability of agriculture to climate change and variability is an issue of major importance to the international scientific community. Greenhouse gas (GHG)-induced climate change would very likely result in significant damage in the agricultural sector in sub-Saharan Africa because the region already endures high heat and low precipitation. General circulation models (GCMs) are the primary source of climate change scenarios which make projections about the degree and timing of climate change. Agriculture has always been dependent on the variability of the climate for the growing season and the state of the land at the start of the growing season. The key for adaptation for crop production to climate change is the predictability of the conditions. What is required is an understanding of the effect on the changing climate on land, water, and temperature.

Published: November 2021

This chapter focuses on the richness and wide variety of Sub-Saharan ecosystems particularly in the region of Tafilalet, Morocco. The Tafilalet ecosystems provide an extensive list of goods (see below) to the region, as well as “ecosystem services” for the inhabitants. However, in the last 30 years, these ecosystems are threatened by conjugated impacts of climate change and human overuse of the nature resources. The primary objective of this chapter is to evaluate both the damage inflicted on Tafilalet ecosystems and the associated ecosystem services due to climate change. Adaptation to climate change is of paramount importance to keep the survival of the diversity of Tafilalet ecosystems including agro-ecosystems, forests, and inland waters. Adaptation is a process to reduce the vulnerability of people to prevent displacement and conflict for scarce ecosystem services. The findings of this chapter show that a large number of ecosystem services of the region are limited by climatic conditions that affect the resilience of the whole oasis of Tafilalet.

Climate change is an actual fact setting off an imbalance in many living systems. Among these affected systems, water is a major essential element in the globe and in every existing living being. Therefore, several complications have been stated to occur, following water scarcity and water flood in many regions of the world, which make of them a global major threat of water security. The global disease burden is an additional factor that appeals to serious interventions worldwide in order to alleviate the water scarcity and water flood-related effects.
