INCOME DISTRIBUTION OF RURAL HOUSEHOLDS IN MEXICO
Authors: Gallardo Del Ángel Roberto , Ojeda Ramírez Mario Miguel , Cruz López Cecilia
Published: November 2021

Despite the efforts to reduce poverty in rural municipalities income inequality persists in Mexico. This study presents an analysis on rural household income distribution in the country, since it is argued that conditional federal transfers fail on improving income distribution among rural households. The hypothesis stated that, because of local public goods are also part of individual budget constraints, it is rational to think that an expansion in the provision of local public goods will increase total income and, if such public goods are financed with conditional grants that target low-income groups, it is expected that income inequality may decrease. Thus, the objective was to classify rural municipalities in order to observe which among them have benefited from federal grants and those that did not, finding the reasons why assuming grants are accepted as an instrument contributing to reduce poverty and income inequality in recent years. Each group was analysed as a cluster to observe the effect of federal transfers on rural household income distribution. Main results showed that municipalities with rural low income-inequality and better economic development indicators improve income distribution when obtaining unconditional grants. This means that, in such cases, those transfers designed to reduce poverty also reduce rural income inequality. But that was not the case for the high income-inequality groups, where conditional grants did not have any effect on inequality and, in some cases, inequality increased. For the rural high income-inequality group, unconditional grants showed not to have a positive effect on reducing inequality. The clustering and regression analyses revealed large heterogeneity in the rural areas in terms of income and economic development.
Moderating influence of social support on the relationship of workplace loneliness and well-being of employees with special needs in Pakistan
Authors: Ramzan Mehwash , Mukarram Sana , Mukarram Aleena , Naveed Shaheryar
Published: November 2021

Workplace Loneliness is a process, which begins with the psychological requirement of belongingness, and exposes on the reality of social relations within the organizations. This research finds out the impact of workplace loneliness of employees with special needs on their psychological well-being with moderating impact of perceived social support from co-workers and managers. For this purpose, 120 employees with special needs working on managerial role, belonging from public (37%), private (32%), and non-governmental (32%) sectors participated as respondents of the questionnaire-based survey, which was developed on a website according to international accessibility standards. The data was collected by circulating it through multiple social media platforms. The analysis of collected data was performed in MS Excel and IBM SPSS Statistics. Results are clearly showing that social support is an important factor in reducing workplace loneliness and in increasing the well-being of employees with special needs. Therefore, these special employees must be treated as differently abled bodies instead of disabled ones. Hindrances including Covid-19 and software inaccessibility were also faced during the whole process. On the basis of this study, future researchers can research further about type of social support that should be provided on workplace to employees with special needs.
Introducción a la sociología constructivista
Authors: Jiménez Nájera Yuri
Published: November 2021

En el libro se expone la perspectiva teórico-metodológica del reconocido sociólogo francés Pierre Bourdieu (1930-2002) –quien hizo grandes aportaciones a las ciencias sociales contemporáneas–, perspectiva subdividida en dos ejes articulados entre sí: el eje constructivista (basado en el supuesto de que la realidad social es una construcción sociohistórica producida por la acción social de agentes determinados) y el eje estructuralista (basado en la consideración de la existencia de estructuras sociales objetivas y exteriores, construidas históricamente, que limitan la acción de los agentes sociales); ejes que permiten hacer una doble lectura estructuralista y constructivista de la compleja realidad social.
La Palestine comme métaphore
Authors: Kolakowski Marc Adam
Published: November 2021

Pour Johann Wilhelm Stucki (1542-1607), les Juifs et Palesti-niens de l’Antiquité se constituent en acteurs d’une scène ou-verte sur le passé, un laboratoire où s’élaborent des solutions pour le présent. En effet, le parallèle est dressé par le polymathe zurichois entre le conflit biblique qui oppose Israël à ses voisins de Palestine et les guerres de religions qui secouent l’Europe de son temps. Fixer l’identité des divers protagonistes revient ici essen-tiellement à décrire sans solution de continuité leurs environne-ments, coutumes et religions : ainsi, le caractère mal défini du territoire palestinien, entre mer et terre, explique l’ambivalence de leurs mœurs et l’aspect des divinités qu’ils ho-norent, figures ambiguës à la fois marines et agricoles. En s’appuyant sur une théorie des climats récemment remise au goût du jour par Jean Bodin (Six Livres de la République, Paris 1576), Stucki rend compte d’un conflit inscrit dans la nature-même des choses. Seule solution politique viable à ses yeux : la reconnaissance mutuelle des différences et leur mise en jeu dans un processus dialectique de vicinitas ou « bon voisi-nage ».
AN APPRAISAL OF VIRTUAL INTERNSHIP IN KENYA: EXPERIENCES AND PERCEPTIONS DURING COVID-19 PANDEMIC
Authors: Ochieng Olayo , Kamau Lewis
Published: November 2021

Purpose: This paper sought to discuss the impact of COVID-19 on Virtual internship. It explores the interns experience and perceptionon virtual internship that was accelerated by the outbreak of COVID-19.

Methodology: The study adopted a cross-sectional study on interns in different companies in Kenya. The study used both close-ended and open-ended online questionnaires to collect data from 161 interns about their experience and perception of switching to virtual internship. The data analyzed quantitatively and qualitatively.

Results: Internship programs were interrupted by COVID-19 pandemic greatly. There was low number of interns in organizations, and management made changes on the scope and intake of interns. Among the changes made by organization was the shift from traditional internship to virtual internship. The virtual interns reported great satisfaction. They reported gaining by learning technical skills and soft skills for remote work.

Unique contribution to theory, practice and policy: The findings of this study contribute and fill the gaps to the literature around virtual internship. The study recommends organizations to adopt policy that allow for virtual internship. The policy should, firstly, provide for orientation of interns. This will enable the interns to understand their scope of work and company culture. Secondly, the policy should clearly provide the most appropriate communication platforms e.g. zoom, WhatsApp, teams etc. Finally the policy should include a framework that will allow interns to attend departmental meetings. This will go a long way in exposing the interns to the company’s work culture and reduce isolation.

Authors: Kravchuk Lyudmila A. , Bazhenova Natalia M. , Gaishun Aleksey N.
Published: November 2021

To assess the environment-forming functions of green areas ("green infrastructure") in Vitebsk using data on the functional types of urban planning structures, various climatopes were identified. In Vitebsk, 17 types and 47 species of climatopes have been identified. Using Earth remote sensing data, a differentiated assessment of the Land Surface Temperature (LST) and the Normalized Vegetation Index (NDVI) was carried out for various types of urban climatopes. The data obtained demonstrate comparatively low average LST values in aquatic, forest, some park climatopes and vegetation in floodplains. In the built-up part of the city LST has the highest values in production, communal,

road climatopes and in the central historical part of the city. The correlation coefficient between LST and the degree of greenery, between LST and NDVI in different types of climatopes of Vitebsk is estimated at –0,78 and –0,77, respectively, which confirms the high environmental-forming role of urban vegetation in summer.
SORPTION MATERIALS BASED ON ALKALI-INSOLUBLE COMPONENTS PEAT AND BROWN COAL FOR WASTEWATER TREATMENT FROM IONS OF HEAVY METAL
Authors: Pershay Natalia S. , Yanuta Yuriy G.
Published: November 2021

The problem of environmental pollution with heavy metals is relevant for the Republic of Belarus. One of the ways to remove heavy metals from industrial wastewater is to treat them with sorbents. Sorbents based on peat and brown coal are effective and inexpensive, but their use leads to secondary contamination of the treated environment with water-soluble organic compounds. It is shown that the developed sorption materials based on peat and brown coal residues sorb heavy metal ions (copper, nickel, zinc) and do not pollute the treated medium with water-soluble organic compounds (the COС value of sorption materials does not exceed 5 mg O2/dm3). It was found that the exchange capacity of sorption materials in an acidic medium (pH 2.0) is higher than that of humic acids and is in the range of 0.17–1.38 mmol/g. The use of ultrasonic treatment to increase the exchange capacity of sorption materials makes it possible to

increase it by 2.3–3.0 times for copper ions and 2.2 times for zinc ions, which is due to the destruction of large aggregates.

The obtained results formed the basis for the development of a technology for obtaining sorption materials for wastewater treatment from heavy metal ions.

Authors: Kuntsevich Victor B. , Makarenko Tatiana I.
Published: November 2021

The generalize desirability function of Harrington which can include a variety of particular parameters such as technological, technical and economic, qualitative characteristics is widely used in the search for optimal conditions in various areas of the national economy. The analysis of the tasks solved during the research and project works showed that this method can be successfully applied in the peat industry. The article, as an example, considers the selection method for the peat deposit from several suitable for extraction of sod peat intended for the production of activated charcoals, which at the current time is the best option. It is shown that the use of the generalized desirability function makes it possible to achieve acceptable results at the stage of preproject preparation, without recourse to complex mathematical calculations, which are the basis of a standard feasibility study. Thus, the proposed method allows to reduce labor and financial costs.

LA TRANSPOSICIÓN DE LA DAC 6 EN ESPAÑA
Authors: Nicolás Cremades Leguina
Published: November 2021

Casi dos años después de su aprobación en el seno de la Unión Europea, la Directiva (UE) 2018/822 (comúnmente conocida como «DAC 6») ha sido finalmente transpuesta al ordenamiento jurídico español. En un contexto en que las operaciones transfronterizas revisten cada vez una mayor complejidad al tiempo que ganan aun mayor presencia en nuestro día a día, los operadores jurídicos y económicos se enfrentarán a partir de ahora al reto de dar cumplimiento a esta nueva obligación de información sobre la que aún se suscitan grandes interrogantes.
COMPATIBILITY OF A EUROPEAN METR MINIMUM TAX WITH EU/EEA FREE MOVEMENT GUARANTEES
Authors: Joachim Englisch
Published: November 2021

Un grupo de académicos asociados a la Tax Justice Network (TJN) ha propuesto recientemente la aplicación de un tipo impositivo mínimo efectivo internacional (METR) para las multinacionales. El METR se ha concebido como una versión revisada y modificada del concepto de impuesto mínimo global de GloBE que actualmente persigue el Marco Inclusivo sobre BEPS de la OCDE/G20. Al igual que GloBE, el METR ha sido diseñado para funcionar como un amplio instrumento contra BEPS. Sin embargo, la asignación internacional de derechos fiscales adicionales en relación con los beneficios que han sido gravados a un nivel demasiado bajo, así como el cálculo del impuesto complementario, diferirían del enfoque GloBE. Más concretamente, el METR se basaría en una fórmula de prorrateo para asignar los derechos de imposición, y permitiría a las jurisdicciones pertinentes recaudar un impuesto complementario proporcional que se corresponda con su propio tipo del impuesto de sociedades.  Este documento analiza la compatibilidad del concepto de METR con los derechos de libre circulación de la UE/EEE. Llega a la conclusión de que el METR daría lugar a menos casos de discriminación -tal como se entiende en la jurisprudencia del TJUE- que un impuesto mínimo GloBE no modificado. Además, es posible adaptar las normas del METR para preservar el concepto básico, garantizando al mismo tiempo la ausencia casi total de un tratamiento fiscal desventajoso de las situaciones transfronterizas. En ese caso, es probable que el T-UE acepte como justificadas las cuestiones marginales restantes.
HACIA UN SISTEMA TRIBUTARIO MÁS JUSTO QUE REDUZCA LA DESIGUALDAD, CONTRIBUYENDO A LA IMPLEMENTACIÓN DE LA AGENDA 2030
Authors: Sofía Arana Landín
Published: November 2021

La realidad de nuestro sistema tributario ya no pasa por la materialidad, ni por la presencia física en que se basan nuestros puntos de conexión en materia tributaria, sino por un mundo digital, interdependiente, globalizado y con una fácil movilidad. La soberanía del Estado ya no sólo se enfrenta a problemas internos, sino que son fundamentalmente transnacionales e interdependientes. Así, no podemos dar respuestas efectivas a la implementación de los Objetivos de Desarrollo Sostenible si no comenzamos por adecuar la tributación a los nuevos tiempos para contribuir a resolver los problemas que nos afectan globalmente. De esta manera avanzaremos en sostenibilidad y equidad.

Análise do discurso de uma publicação ‘antivacina’ no youtube e algumas reflexões para a educação em ciências
Authors: Melo Leonardo Wilezelek Soares de , Broietti Fabiele Cristiane Dias , Salvi Rosana Figueiredo
Published: November 2021

O objetivo deste artigo foi apresentar uma pesquisa que analisou o discurso em uma publicação ‘antivacina’ no YouTube. O estudo se pautou na seguinte questão de investigação: que relações podem ser evidenciadas entre um discurso ‘antivacina’ e disposições de pensamento crítico? A análise discursiva foi encaminhada conforme Maingueneau, e algumas contribuições sobre pensamento crítico foram consideradas. As perspectivas de Paul Feyerabend e Bruno Latour foram assumidas para justificar um posicionamento simétrico frente ao discurso analisado. Como resultados identificamos a relutância de teóricos da conspiração frente a evidências e informações científicas, a demarcada oposição aos conhecimentos científicos e o caráter ideológico desses discursos. Teorias conspiratórias parecem fazer parte de um sistema cultural e psicossocial complexo, não exclusivamente relacionado às disposições de pensamento. Consideramos que esta pesquisa pode contribuir para as discussões referentes à investigação de teorias conspiratórias e para tornar esse um foco de pesquisa frutífero para a Educação em Ciências.

Published: November 2021

O objetivo deste artigo foi divulgar o resultado da investigação sobre a constituição dos saberes da Lógica no curso de formação de professores de matemática da Universidade Estadual de Feira de Santana. Para isso, realizamos um estudo das ferramentas teórico-metodológicas apresentadas por Hofstetter e Schneuwly (2017) sobre os saberes profissionais constituídos para o ensino e a formação de professores. A discussão foi pautada por uma análise dos projetos político-pedagógicos desta Universidade desde a implantação do curso de Licenciatura Plena em 1976, passando pelo currículo 314 até o currículo 318-atualizado em 2018. A disciplina que trata dos saberes da Lógica pelos professores neste curso de formação de professores foi constituída no Departamento de Ciências Humanas e Filosofia sob o título de Tópicos Especiais em Lógica migrando para o Departamento de Ciências Exatas com o nome de Lógica Matemática e Teoria dos Conjuntos implantada no currículo 318. Sendo educadores matemáticos, entendemos que os conteúdos transversais da Lógica são tratados nas demais disciplinas do curso o método dedutivo com teoria dos conjuntos como linguagem ou mesmo quando utilizados testes matemáticos, saberes de lógica proposicional e lógica de predicados.

Published: November 2021

O presente estudo buscou identificar e analisar dissertações e produtos educacionais desenvolvidos no âmbito dos Mestrados Profissionais em Ensino de Física e Astronomia no Brasil, de 2003 até 2019, visando oferecer um panorama das práticas didáticas preocupadas com a Educação para as Relações Étnico-Raciais (ERER) levando em conta as Lei 10.639/2003 e 11.645/2008. Usando metodologia qualitativo-interpretativa, encontramos que apenas 0,3% de um total de 1262 trabalhos têm se preocupado em levar para sala de aula e, especificamente, para as aulas de Física/Ciências, discussões inerentes à promoção de ERER. Embora, atualmente incipiente, concluímos que o Mestrado Profissional, ao promover o reconhecimento e a valorização da história, cultura e identidade de grupos historicamente discriminados no Brasil, pode ser um agente importante na efetivação da educação antirracista, por sua característica de capilaridade no território nacional e com potencial para disseminação de resultados da própria pesquisa produzida na área.
Strukturdynamische Analyse mittels elektromechanischer Schwingungssensoren
Authors: Herfert Daniel
Published: November 2021

Um die Reproduzierbarkeit erzeugter Schwingungen zu erhöhen, wird in der vorliegenden Arbeit zunächst ein Aktor zur Strukturanregung vorgestellt, der Sensordaten unmittelbar im Gerät auswertet und auf Bewegungen des Hammerarms rückkoppelt. Neuartige Algorithmen werden angegeben, die deutlich Strukturkonfiguration und Messaufwände durch automatische Bestimmung der Sensorpositionen und –orientierungen vereinfachen. Sie ermöglichen, untersuchte Strukturen effizient dreidimensional in Form geometrischer Objekte rechnerunterstützt nachzubilden sowie Messdaten kabellos zu übertragen. Unter realen Anregungsbedingungen lassen sich Schwingungsmuster von Strukturen in geometrische Modelle und Videobilder von ihnen einbetten sowie in Echtzeit am Prüfort unmittelbar visualisieren und auswerten. Diese neuen Möglichkeiten reduzieren den zeitlichen Aufwand und vereinfachen strukturdynamische Analysen deutlich.

Effects of the COVID-19 Pandemic on Physical Activity Behavior Across Domains and Settings
Authors: Besenyi Gina , Pruneda Oziel , Mailey Emily , Deblauw Justin , Beattie Cassandra , Gustat Jeanette , Heinrich Katie
Published: November 2021

Background: COVID-19 restrictions and alterations to daily living (e.g. working from home, caregiving responsibilities) necessitated changes in physical activity (PA) behavior.

Purpose: The purpose of this study is to understand how PA within specific domains and behavior settings changed during the COVID-19 pandemic.

Methods: An e-survey, conducted April-June 2020, examined changes in PA across domains and settings in a national sample of adults (N=805; M age=38.7 ± 14.9 yrs; 78.0% female).

Results: Respondents reported domain-specific increases in household and recreational PA, but decreases in active transportation, occupational PA, and public transportation use. Weekly minutes of PA changed significantly across all behavior settings, with reported increases in home-based, neighborhood, parks/trails, and total PA, and decreases in PA through recreational sports and fitness facilities. Total weekly PA minutes increased by 10.6% (Z= 4.428, p < .000). Those with caregiving responsibilities reported increases in household PA (2=9.82, p=0.007) and PA frequency (2=8.21, p=0.02). Those without caregiving responsibilities were more likely to report increases in sitting (2=20.55, p<0.001). Those working from home reported a larger increase in neighborhood PA (F(1,638)=4.93, p=.027). Those working at a jobsite that also had caregiving responsibilities reported less weekly PA, while those working from home with caregiving responsibilities reported greater weekly PA (F(1, 646) = 4.23, p = .04).

Atuação do Programa Nacional De Alimentação Escolar e aquisição de alimentos provenientes da agricultura familiar durante a pandemia Covid–19
Authors: Reis Nogueira Garcia Jaciara , Carniatto Irene , Nogueira Neto Daniel Felício
Published: November 2021

Este artigo apresenta a experiência da execução do Programa Nacional de Alimentação Escolar (PNAE) no Município de Marechal Cândido Rondon, Paraná, Brasil, durante a pandemia do covid-19. Kits de alimentação foram distribuídos às famílias dos estudantes matriculados nas instituições municipais de ensino. Foi realizado um levantamento documental e analisada a lista de alimentos adquiridos durante o ano de 2020. Como resultado, verificou-se que a inclusão e a valorização dos agricultores no processo de compras institucionais geraram renda e redução do desperdício da produção de alimentos da agricultura familiar local. Houve também o fornecimento de alimentação adequada, saudável e sustentável para as crianças e suas famílias durante a pandemia. Conclui-se que o PNAE pode ser instrumento de promoção da saúde e segurança alimentar e nutricional, reduzir tanto os efeitos negativos da pandemia na zona rural, como a fome e a pobreza no Brasil.
A meteorological overview of the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) campaign over the southeastern Atlantic during 2016–2018: Part 1 – Climatology
Authors: Ryoo Ju-Mee , Pfister Leonhard , Ueyama Rei , Zuidema Paquita , Wood Robert , Chang Ian , Redemann Jens
Published: November 2021

Abstract. In 2016–2018, the ObseRvations of Aerosols above CLouds and their
intEractionS (ORACLES) project undertook 3-month-long deployments to the
southeastern (SE) Atlantic Ocean using research aircraft to better understand the impact of biomass burning (BB) aerosol transport to the SE Atlantic Ocean on climate. In this (part 1 of the meteorological overview) paper, the climatological features at monthly timescales are investigated. The southern African easterly jet (AEJ-S), defined as the zonal easterlies over 600–700 hPa exceeding 6 m s−1 around 5–15∘ S, is a characteristic feature of the mid-level circulation over southern Africa that was also during the deployment months of August 2017, September 2016, and October 2018. Climatologically, the AEJ-S develops at lower altitudes
(∼ 3 km; 700 hPa) between 5–10∘ S in August, while
it develops at around 4 km (∼ 600 hPa) and further south
(5–15∘ S) in September and October, largely driven by the strong
sensible heating over the African plateau. Notable meteorological anomalous characteristics during the 3 deployment months, compared to climatology (2000–2018), include the following: (1) during August 2017, the AEJ-S was weaker than the climatological mean, with an additional anomalous upper-level jet aloft (∼ 6 km) around 10∘ S. August 2017 was also drier over the SE Atlantic at 600–700 hPa than climatology, with a stronger Benguela low-level jet (LLJ) at 925–950 hPa along the Namibian coast of the SE Atlantic. Consistent with this, the southern Atlantic anticyclone was also stronger and closer to the coast than the August climatological mean. (2) During September 2016, the AEJ-S intensity was similar to the climatological mean, although the heat low and vertical motion over the land was slightly stronger compared to the September climatology. The LLJ and the large-scale southern Atlantic anticyclone were stronger than the climatological mean. (3) During October 2018, the AEJ-S was slightly weaker compared to the climatological mean, as was the LLJ and the southern Atlantic anticyclone. October 2018 was wetter over the Benguela coastal region at 600 hPa than the climatological mean. During all the deployment months, the sea surface temperatures (SST) over the SE Atlantic were warmer than the climatological means, but the monthly mean low cloud fraction was only noticeably reduced in August 2017. A weak August 2017 AEJ-S can explain low offshore black carbon (BC) mixing ratios within the European Centre for Medium-Range Weather Forecasts (ECMWF) Copernicus Atmosphere Monitoring Service (CAMS) reanalysis, although the BC peak altitude, at 2–3 km, is below that of the AEJ-S. The upper-level wave disturbance and the associated anomalous circulation also explain the weakening of AEJ-S through the reduction of the strength of the heat low over the land during August 2017.
Evaluating Flow in Fractal-Fracture Networks: Effect of Variable Aperture
Authors: Sahu Ajay K. , Roy Ankur
Published: November 2021

Abstract. While fractal models are often employed for describing the
geometry of fracture networks, a constant aperture is mostly assigned to all
the fractures when such models are flow simulated. In nature however, almost
all fracture networks exhibit variable aperture values and it is this
fracture aperture that controls the conductivity of individual fractures as
described by the well-known cubic-law. It would therefore be of practical
interest to investigate flow patterns in a fractal-fracture network where
the apertures scale in accordance to their position in the hierarchy of the
fractal. A set of synthetic fractal-fracture networks and two well-connected
natural fracture maps that belong to the same fractal system are used for
this purpose. A set of dominant sub-networks are generated from a given
fractal-fracture map by systematically removing the smaller fracture
segments with narrow apertures. The connectivity values of the
fractal-fracture networks and their respective dominant sub-networks are
then computed. Although a large number of fractures with smaller aperture
are eliminated, no significant decrease is seen in the connectivity of the
dominant sub-networks. A streamline simulator based on Darcy's law is used
for flow simulating the fracture networks, which are conceptualized as
two-dimensional fracture continuum models. A single high porosity value is
assigned to all the fractures. The permeability assigned to fractures within
the continuum model is based on their aperture values and there is nearly no
matrix porosity and permeability. The recovery profiles and time-of-flight
plots for each network and its dominant sub-networks at different time steps
are compared. The results from both the synthetic networks and the natural
data show that there is no significant decrease in fluid recovery in the
dominant sub-networks compared to their respective parent fractal-fracture
networks. It may therefore be concluded that in the case of such
hierarchical fractal-fracture systems with scaled aperture, the smaller
fractures do not significantly contribute to connectivity or fluid flow. In
terms of decision making, this result will aid geoscientists and engineers
in identifying only those fractures that ultimately matter in evaluating the
flow recovery, thus building models that are computationally less expensive
while being geologically realistic.
Automated snow avalanche release area delineation in data sparse, remote, and forested regions
Authors: Sykes John , Haegeli Pascal , Bühler Yves
Published: November 2021

Abstract. Potential avalanche release area (PRA) modelling is critical for generating automated avalanche terrain maps which provide low-cost large scale spatial representations of snow avalanche hazard for both infrastructure planning and recreational applications. Current methods are not applicable in mountainous terrain where high-resolution elevation models are unavailable and do not include an efficient method to account for avalanche release in forested terrain. This research focuses on expanding an existing PRA model to better incorporate forested terrain using satellite imagery and presents a novel approach for validating the model using local expertise, thereby broadening its application to numerous mountain ranges worldwide. The study area of this research is a remote portion of the Columbia Mountains in southeastern British Columbia, Canada which has no pre-existing high-resolution spatial data sets. Our research documents an open source workflow to generate high-resolution DEM and forest land cover data sets using optical satellite data processing. We validate the PRA model by collecting a polygon dataset of observed potential release areas from local guides, using a method which accounts for the uncertainty of human recollection and variability of avalanche release. The validation dataset allows us to perform a quantitative analysis of the PRA model accuracy and optimize the PRA model input parameters to the snowpack and terrain characteristics of our study area. Compared to the original PRA model our implementation of forested terrain and local optimization improved the percentage of validation polygons accurately modelled by 11.7 percentage points and reduced the number of validation polygons that were underestimated by 14.8 percentage points. Our methods demonstrate substantial improvement in the performance of the PRA model in forested terrain and provide means to generate the requisite input datasets and validation data to apply and evaluate the PRA model in vastly more mountainous regions worldwide than was previously possible.
Évolution du régime hydrologique dans le bassin versant du Bouregreg, Maroc
Authors: El Aoula Rajae , Mahé Gil , Mhammdi Nadia , Ezzahouani Abdellatif , Kacimi Ilias , Khomsi Kenza
Published: November 2021

Abstract. Le Bouregreg est le deuxième fleuve du Maroc. Il draine
les eaux du centre du Maroc, du Moyen Atlas à l'Atlantique, qui sont
stockées dans la retenue du barrage Sidi Mohamed Ben Abdellah
créé en 1974 et situé à proximité de Rabat. Sa fonction
exclusive est l'alimentation en eau potable pour les besoins individuels et
industriels de 6 millions d'habitants de la bande littorale allant de
Kénitra à Casablanca. Toutefois, l'exploitation de cette retenue
présente aujourd'hui quelques incertitudes surtout en considérant
l'augmentation de la population, la baisse des volumes précipités
depuis 1979 et le comblement de la retenue par le transport de sédiments
dus à l'érosion des sols. L'objectif de cette étude est de
d'écrire l'évolution des pluies et des débits du bassin versant
du Bouregreg à partir des séries de pluie et débit sur une
période de 36 ans, de 1977 à 2013. Nous avons utiliséì les
indices pluviométrique et hydrométrique, dans le but de
caractériser l'hétérogénéité temporelle de la
variabilité climatologique et dégager les grandes tendances des
séries de données hydroclimatologiques. L'évolution des indices
pluviométriques et hydrométriques met en relief la période
déficitaire qu'a connu le Maroc au début des années 80. En
effet, une baisse générale des pluies est remarquée dans le
bassin versant du Bouregreg depuis 1979, ainsi il existe des relations entre
la variabilité des pluies de certaines régions et l'Oscillation Nord
Atlantique en 1996. Les méthodes statistiques de détection de
ruptures montrent que la période de rupture majeure se trouve durant la
deuxième moitié des années 70 et le début des années 80.
Depuis cette date la baisse de la pluviométrie s'est installée de
manière significative, et une perturbation du régime hydrologique
est observée sur la presque totalité du bassin versant du Bouregreg,
même si quelques années de meilleures pluviométries ont
été observées à la fin des années 2000.

Abstract. This study aims to analyse the frequency, intensity and duration
of extreme climate events in order to optimise sugarcane production in the
Ferkessédougou sugar complexes. The methodological approach is based on
the calculation of extreme climate indices defined by the Expert Team on
Climate Change Detection and Indices (ETCCDI) from daily rainfall and
temperature data observed at the Ferké 2 station over the period
1999–2018. The results show that the rainfall indices are negative, except
for the number of consecutive dry days (CDD); this shows a decreasing trend
in rainfall with, however, insignificant trends. Over the period 1999–2006,
the number of intense rainfall days (R10 mm) decreased from 40 to 28 d with an average decrease of 0.3 d yr−1 and the number of very
intense rainfall days (R20 mm) fluctuated between 26 and 2 d, with a slope
of 0.083. The extreme temperature indices show statistically significant
positive trends for the warm sequences; this confirms the rising of
temperatures on both a local and national scale. This study could enable the
Ferkessédougou sugar complexes managers to develop strategies for
adaptation to climate change.
Seasonal flow forecasting in Africa; exploratory studies for large lakes
Authors: Sene Kevin , Tych Wlodek
Published: November 2021

Abstract. For many applications, it would be extremely useful to have insights into river flows at timescales of a few weeks to months ahead. However, seasonal predictions of this type are necessarily probabilistic which raises challenges both in generating forecasts and their interpretation. Despite this, an increasing number of studies have shown promising results and this is an active area for research. In this paper, we discuss insights gained from previous studies using a novel combined water balance and data-driven approach for two of Africa's largest lakes, Lake Victoria and Lake Malawi. Factors which increased predictability included the unusually long hydrological response times and statistically significant links to ocean-atmosphere processes such as the Indian Ocean Dipole. Other lessons learned included the benefits of data assimilation and the need for care in the choice of performance metrics.
Pratiques endogènes de gestion de l'eau au service des politiques d'adaptation aux changements climatiques dans la région du lac Tchad
Authors: Sambo Armel
Published: November 2021

Abstract. Dans un contexte-marqué par la variabilité climatique comme la
région du lac Tchad, il est utile de prendre en compte et de revaloriser
les stratégies d'adaptation aux phénomènes induits par les
Changements Climatiques (CC), dans le but d'améliorer la gestion durable
des ressources en eau. Cette étude vise donc à identifier et à
interpréter les pratiques locales de gestion et d'accès à l'eau,
des dynamiques de celles-ci, et son importance dans la cadre de mises en
œuvre des projets d'adaptation aux changements climatiques dans la
région du lac Tchad. La méthodologie adoptée a consisté
d'abord à la collecte des données (par des entretiens, observation,
etc.) auprès des populations riveraines du lac Tchad, ensuite à leur
traitement analyse et enfin la rédaction de cet article. Ainsi, quelques
techniques issues de savoir faire traditionnel et local, ont été
identifiées et sont susceptibles d'être revalorisées dans un
cadre stratégique. Il s'agit : l'existence des mares d'eau sacrée, la
gestion collective des mares d'eau naturelles, la gestion communautaire des
pêcheries, l'irrigation, etc. Toutes ces pratiques et techniques ont
été inventées et ou améliorées par les populations pour
répondre à des contraintes de production qu'ils connaissent bien.
