Exploraciones sobre el proceso de bancarización que implican los Programas de Transferencia Condicionada de Ingresos en la Ciudad de Buenos Aires
Authors: Chahbenderian Florencia
Published: April 2023

Este artículo estudia las formas bajo las cuales los Programas de Transferencia Condicionada de Ingresos (PTCI) implementados en la Ciudad Autónoma de Buenos Aires (CABA) inscriben a sus receptores en el sistema bancario, de modo de establecer las ligazones entre la implementación de los PTCI, las prácticas de consumo de sus receptoras y su participación en las instituciones bancarias. Para ello, se recorre el proceso de bancarización, junto con sus implicancias en el despliegue de destrezas emocionales y en el “blanqueo” de las prácticas de consumo. La estrategia de indagación es cualitativa, basada en la realización de entrevistas semi-estructuradas a informantes claves: a) que estén involucrados en la gestión de los mencionados PTCI; b) que otorguen créditos al consumo dentro del sector formal; c) sujetos que viven en la CABA, reciben algún PTCI y accedan a algún crédito para el consumo. Complementariamente, se efectúa un análisis documental mediante el estudio de producciones estatales y académicas que analizan y describen los programas bajo estudio. El trabajo concluye que el ser sujetos receptores de PTCI los lleva a constituirse como sujetos de crédito; este es un fin buscado por estos programas – de forma más o menos explícita –, bajo los argumentos de la inclusión financiera.

Se concluye con reflexiones sobre los retos y desafíos de su estudio y abordaje.
Apuntes sobre la dimensión social de los procesos salud-enfermedad
Authors: Mauriz Georgina
Published: April 2023

La enfermedad es en principio un fenómeno biológico, que es ocasionada por algún tipo de factor interno o externo al individuo. Ahora bien, ese fenómeno biológico tiene consecuencias sobre la trama social, al mismo tiempo que su desarrollo adquiere características concretas dependiendo del espacio geográfico e histórico en que se sitúa. Desde las últimas décadas del siglo XX, el diálogo entre las ciencias sociales y las ciencias biomédicas amplió el enfoque sobre el tema, permitiendo estudiar el proceso salud-enfermedad no sólo como un proceso biológico, sino también atendiendo a sus connotaciones sociales. Bajo esta premisa, el presente aporte pretende abordar, mediante la ilustración de algunas epidemias que azotaron la República Argentina entre el siglo XIX y el siglo XX, dos fenómenos que tienden a repetirse en estas coyunturas y dejan al descubierto la relación intrínseca que guardan los periodos de crisis sanitaria con los procesos sociales. Por un lado, se planteará el modo en que las enfermedades se han convertido a lo largo de la historia en ocasiones potenciales para el desarrollo y legitimación de políticas públicas y grupos de poder. Para ilustrar se retomarán los trabajos de Diego Armus (2000, 2007) sobre el desarrollo del higienismo en Argentina y la historia de la tuberculosis. Por otro lado, se observará mediante los trabajos de Álvarez (2021) y Carbonetti (2010) sobre el cólera y la gripe española, la forma en que las desigualdades estructurales de las sociedades terminan exacerbándose durante estos periodos, impactando y perjudicando a los sectores más vulnerables.

Актуальность. Флюиды месторождений на территории Российской Федерации обладают высоким содержанием серосодержащих соединений, в частности сероводорода. Ввиду такой особенности многие газо- и нефтедобывающие компании теряют выручку с продажи подобного углеводородного сырья. Содержание сероводорода во флюиде на месторождении Х выше 5 масс. %. На данный момент попутный нефтяной газ поставляется на газоперерабатывающем заводе по стоимости 2400 р. за 1000 м3, вследствие чего экономическая эффективность рассматриваемого проекта падает. Для решения данной проблемы предложено строительство блока подготовки попутного нефтяного газа до требований системы стандартизации ОАО «Газпром» (СТО Газпром) «Газ горючий, природный, поставляемый и транспортируемый по магистральным газопроводам» (089-2010) в рамках реинжиниринга объекта подготовки нефти и газа, что позволит сбывать попутный нефтяной газ по цене 4500 р. за 1000 м3. Цель: сформировать концепцию повышения рентабельности проекта в рамках реинжиниринга с помощью предложенного решения очистки попутного нефтяного газа от сероводорода и получения серы из кислого газа. Методы: поиск и анализ достоинств и недостатков технологий очистки газа, моделирование выбранной технологии в ПО «Hysis» для определенной производительности и получение материального баланса для проектирования установки. Результаты. Процесс подготовки газа предусматривает сепарацию, блок абсорбционной очистки попутного нефтяного газа от сероводорода и диоксида углерода аминами, блок адсорбционной осушки газа по извлечению меркаптанов и осушке цеолитами NaX (13X) и блок извлечения элементарной серы. Выводы. В ходе моделирования получена схема аминной очистки газа с параметрами материального баланса, согласующимися с требованиями системы стандартизации ОАО «Газпром» (СТО Газпром) «Газ горючий, природный, поставляемый и транспортируемый по магистральным газопроводам» (089-2010). Вследствие чего полученный газ рекомендуется подавать в единую систему газоснабжения. Кислые газы утилизируются при помощи смоделированной установки Клауза.

Актуальность исследования. Мировой спрос на уголь в 2022 г. достиг исторического максимума 2013 г. и составил 8 млрд т. Увеличение спроса на уголь привело к интенсификации его добычи и, соответственно, к увеличению количества техногенных отходов – породных отвалов. Породные отвалы опасны для окружающей среды, однако их химический состав позволяет рассматривать породные отвалы как техногенные месторождения. Цель: разработка ресурсосберегающей технологии утилизации породных отвалов горнодобывающей промышленности с получением глинозема и других полезных компонентов. Объект: породные отвалы угольных шахт. Методы: экспериментальные исследования влияния режима спекания шихты аргиллит–сода‒мел на степень извлечения глинозема из аргиллита и на качество спека: определение массовой доли оксида алюминия титриметрическим методом; определение количества диоксида углерода в образцах волюмометрическим методом; определение потери влаги и продуктов реакций при прокаливании гравиметрическим методом. Результаты. Проведен анализ содержания полезных компонентов в породных отвалах Донбасса, а также существующих технологий извлечения глинозема из техногенных месторождений с низким содержанием алюминия. Техногенные отходы могут быть значительной сырьевой базой производства на многие годы. Кроме получения востребованной продукции, переработка техногенных отходов позволит повысить уровень экологической безопасности горнопромышленных агломераций. Рассмотрена технология утилизации породных отвалов с применением метода спекания шихты порода–сода–мел. В ходе экспериментальных исследований было установлено, что метод спекания с добавлением соды, несмотря на относительно небольшой процент извлечения глинозема (75,2 %), позволяет значительно снизить температуру спекания шихты (до 850 °С) и повысить энергоэффективность метода.

Background: During perinatal period, the immune system of calves is developing, making them vulnerable to infectious diseases that affect their growth or increasing mortality. Phytobiotics have various physiological effects on animals that could improve their performance and health. In this study, the effect of a feed herbal mixture made from Azadirachta indica and Phyllanthus niruri were evaluated in dairy calves. Methods: Forty Holstein calves were assigned into four groups (doses of 0, 2, 3 and 4 g d-1) and productive and health parameters were recorded. Results were analyzed according to a completely randomized design in which linear and quadratic effects of daily feed additive dose were tested. Result: Increasing the dose of herbal mixture linearly reduced final body weight, body weight gain and daily calve starter intake, although it improved feed conversion. Blood tests showed that hematocrit and hemoglobin increased quadratically. The number of segmented neutrophils increased linearly. Finally, the number of pneumonia cases decreased quadratically. These results suggest that supplementation with herbal additives could improve feed efficiency and improve the health status of calves.

Published: April 2023

Recently, science, technology, engineering and mathematics (STEM) applications have become more demanding, promoting students' interest in science from an early age. Science class in primary school needs more attention to attract students’ interest. This study aims to develop an inquiry- based module with scientific equipment for the primary school level to optimize science learning at the primary school level. The development process used a 4-D (define, design, develop and   disseminate) model. The developed module and   equipment cover the topics of forces and include four experiments, i.e., exploring friction in inclined planes, exploring the mechanical advantage of a pulley, observing magnetic force   and exploring static equilibrium in a lever. The modules and   scientific equipment are distributed to some schools in Indonesia that lack practical work facilities. The inquiry-based modules and scientific equipment are implemented in classes at four primary schools in Indonesia. In this study, the students' response to the implementation of inquiry-based modules and scientific equipment in the class is also investigated. Overall, the average of the   students' responses is 3.37 (out of 4.00). It means students respond positively to the learning activity and the supporting module. Active learning with an inquiry approach is feasible to attract students' interest in science.

Quanto à metodologia utilizada neste artigo, temos uma pesquisa exploratória e bibliográfica, e a abordagem qualitativa. Como resultados deste estudo, destaca-se a utilização do Teorema do Passo da Montanha, que fornece algumas condições do funcional, entre elas a condição de Palais-Smale, sob as quais o funcional associado à equação tem ponto crítico. Conclui-se, no final da pesquisa, que os métodos em questão são uma ferramenta poderosa para resolução de determinadas equações diferenciais ordinárias, cujos métodos tradicionais não são suficientes para resolver.
An empirical investigation of the relationship between government revenue, expenditure, and economic growth in selected EMEs
Authors: Suresh Anoop K , Seth Bichitrananda , Behera Samir Ranjan , Rath Deba Prasad
Published: April 2023

Purpose ─ This article explores the relationship between government revenue, government expenditure, and economic growth for nine emerging market economies using annual data from 1991-92 to 2019-20.
Method ─ This paper distinguishes itself from the existing literature through the application of co-integration tests, vector error correction, DOLS and FMOLS for an empirical investigation of a unique panel data set of select emerging economies across Asia, Africa, Europe and Latin America. A bi-directional causal long-run relationship between economic growth and government expenditure, as well as between government expenditure and government revenue, was found using standard panel co-integration tests.
Findings ─ The long-run elasticities computed using VECM were confirmed from DOLS as well as FMOLS estimates. A one per cent increase in expenditure and revenue, in the long run, would result in an increase in GDP by 0.94 and 0.90 per cent, respectively. Similarly, an increase in GDP by one per cent would lead to an increase in government expenditure by 1.1 per cent. On the other hand, an increase in government revenue by one per cent would cause a corresponding increase in government expenditure by nearly one per cent. The findings of this research point to a positive association between government revenue, expenditure, and economic growth, which will be valuable to policymakers.
Contribution ─ Our combination of country selection covering economies from different continents is a first of its kind to the best of our knowledge. Another contribution is the application of panel cointegration and panel error correction techniques to fully use the panel data set, while most previous studies utilised the typical time series modelling with individual time series data.

Published: April 2023

Shallots (Allium ascalonicum) are one of the important horticultural export commodities in Indonesia, but the productivity of shallots has decreased due to the attack of pathogenic fungi. This study was aimed to determine the potential of active shallot compounds as ligands for inhibiting the activity of the enzyme lanosterol 14-alpha demethylase (ID: 4LXJ) and squalene monooxygenase (ID: 6C6R) enzymes which play an important role in the biosynthesis of ergosterol or fungal cell membranes. The molecular docking used the Autodock Vina (PyRx) program, an analysis of molecule interaction used PyMol, and Discovery Studio 2019 to analyze the types of bonds between molecules. Thirty-nine ligands from shallot compounds are docked to the anti-fungal target protein. The results showed ascalonicoside A1, ascalonicoside A2, ascalonicoside B, quercetin, isorhamnetin, quercetin di glucoside, quercetin tri glucoside, ethyl palmitate and benzyl salicylate have the potential to be anti-fungal to the enzyme lanosterol 14-alpha demethylase and squalene monooxygenase enzyme that responds to the synthesis of fungi cell wall. These ligand compounds bind to the target protein's amino acid residues with hydrogen and hydrophobic bonds. This research showed that shallot was the potential to be replicated as an anti-fungus for many purposes.

Authors: Dinurrosifa Rahmawati Salsa , Indriyanti Erwin
Published: April 2023

Clove oil is an essential oil from the clove plant (Syzygium aromaticum) containing eugenol compounds. One of the properties of eugenol is as an anti-inflammatory with a mechanism of inhibition of prostaglandin synthesis and neutrophil chemotaxis. Several derivatives of eugenol have active compounds that have been developed into new drug compounds as anti-inflammatory such as acetyl eugenol (4-allyl-2-methoxyphenyl acetate). This study aims to determine the % yield of acetyl eugenol produced from synthesis using ultrasonic 0.0323 mol of eugenol added to Erlenmeyer, and 0.25 mol of 10% sodium hydroxide was added. The mixture was put in a sonicator for 15 minutes and heated at 600C. Then, 0.0974 mol acetic anhydride was reacted with DCC, added to the mix and sonicated with time variations (60, 80, and 100 minutes). The chemical structure was elucidated using FTIR, ATR, and GC-MS. The synthesized % yield is 32.75%. Based on the interpretation data from FTIR, 3405 cm-1 is an O-H group (free phenol), 1405 cm-1 is an alkene group (C=C) aliphatic, and 1560 cm-1 is an aromatic compound with the presence of a C=C aromatic bond. The presence of the (C-O) ether group is indicated in the wave number at 1301 cm-1. The C=O ester bond in the ester group is shown at 1700 cm-1. GC-MS shows that the synthesized compound has a molecular ion with m/z = 206. According to the molecular weight of acetyl eugenol of 206 g/mol, it can be concluded that acetyl eugenol was successfully synthesized. The most stable ionic fragment, 37, has a molecular weight of m/z = 164. The activities of anti-inflammatory, acetyl eugenol compounds at 400 concentration ppm get % inhibition of 32.20%.

Published: April 2023

This study focuses on synthesizing 4’-bromochalcone through conventional and irradiation microwave methods to determine each method's time efficiency and yield. 4-Bromoacetophenone was treated with benzaldehyde in the presence of a base. Conventionally, the reaction mixture was stirred at room temperature. While in the microwave irradiation method, the reaction mixture was irradiated at a power of 140 watts. The compound was identified, including the melting point and physicochemical properties. The structure of the compound was confirmed by infrared, 1H- and 13C-nuclear magnetic resonance, and mass spectroscopy spectral data. The results showed that 4’-bromochalcone had been successfully synthesized using conventional and microwave irradiation methods in a good yield (94.61%±0.6793 and 89.39%±0.6418, consecutively). The structure assignment based on infrared, 1H- and 13C-nuclear magnetic resonance, and mass spectroscopy spectral data revealed that the synthesized product was 4’-bromochalcone. Synthesis of 4’-bromochalchone using microwave irradiation could be done in a shorter time than the conventional method.

Published: April 2023

This study aims to determine students' critical thinking skills by applying flipped classrooms using the Powtoon application on the topic of salt hydrolysis. This study, which included 36 participants—15 men and 21 women—used a descriptive methodology and was carried out at one of Jakarta's public high schools. The instrument used was an observation sheet to observe the flipped classroom model’s learning process, critical thinking skills tests, reflective journals, and depth interviews. The flipped classroom method entails four steps: pre-class by studying independently and providing stimuli. In-class by fostering critical thinking; and post-class by evaluating. Combining asynchronous and synchronous activities was the process. Students learn independently during the pre-class stage by answering pre-learning questions and watching videos. During the class phase, Zoom meetings are used for synchronous learning to discuss salt hydrolysis applications in particular contexts. Discussion assignments on the salt hydrolysis case help students learn asynchronously after class. The study results showed that the flipped classroom using the Powtoon application can be an alternative for distance learning and can influence the students’ critical thinking at a very good level. It also helps them be more active and critical in learning, like exchanging opinions with others and doing assignments on the topic of salt hydrolysis.

Tenun Ikat Bandar Kidul memiliki beragam motif dan corak yang tiap motifnya sarat akan makna dan mengandung sejarah yang panjang. Namun, minat generasi muda akan tenun ikat ternyata tidak sejalan dengan berbagai kebijakan pemerintah Kota Kediri dalam melestarikan serta mendukung para pengrajin, maka dari itu perlu adanya upaya dalam menanamkan kecintaan akan tenun Ikat kepada generasi muda sejak dini agar Budaya Tenun Ikat di Bandar Kidul tetap lestari dan terjaga. Dalam mewujudkan hal tersebut, Tim Pengabdian Universitas Negeri Malang Tahun 2022 mengadakan kompetisi fashion show bagi anak-anak yang berusia maksimal 12 tahun. Metode yang Tim Pengabdian Universitas Negeri Malang gunakan yaitu observasi, perencanaan, sosialisasi, pelaksanaan, partisipasi serta evaluasi. Hasilnya para peserta yang terdiri dari anak-anak terlihat sangat antusias serta bersemangat dalam mengikuti kegiatan tidak hanya itu para orang tua pun juga terlihat antusias akan penampilan anak-anak mereka. Dari adanya kompetisi ini anak-anak sekitar sebagai calon generasi penerus mulai mengetahui keberadaan tenun ikat Bandar Kidul serta nantinya dapat mencintai dan meneruskan usaha tenun ikat tersebut sehingga budaya tenun ikat dapat tetap terjaga.

Vom Leidensträger zum Leistungsträger
Authors: Greenleaf Jonathan
Published: April 2023

In dieser ethnografischen Studie wurde mithilfe von teilnehmender Beobachtung, Durchführung und systematischer Analyse von Interviews sowie Rückgriff auf sozialwissenschaftliche Literatur die Frage beantwortet, welche Lerneffekte eine Beteiligung von Menschen mit Beeinträchtigung an einer Museumsführung haben kann. Diese Beteiligung fand im Rahmen eines partizipativen Kooperationsprojektes der Lebenshilfe Frankfurt und sieben Frankfurter Museen in Teams von Menschen mit und ohne Beeinträchtigung statt. Die Lerneffekte zeigen sich in Form eines Kreislaufs, der von Teilgabe zur Aufdeckung der Formatierungen von Beteiligung, zu Agency und über die Eröffnung von neuen Möglichkeitsräumen zu einer Demokratisierung von Wissen und damit wieder zu neuer Teilgabe führt. Es handelt sich deshalb um einen nachhaltigen Kreislauf, von dem alle Beteiligten – institutionell sowie individuell – in vielfältiger Hinsicht profitieren. Menschen mit Beeinträchtigung entwickeln sich innerhalb dieses Kreislaufs vom Leidensträger zum Leistungsträger.
Partizipation erlernen?
Authors: Sorokowski Athene
Published: April 2023

Digitale Informationstechnologien werden seit Beginn der 2000er-Jahre hinsichtlich neuer Partizipations- und Demokratisierungsmöglichkeiten diskutiert. In der aktuellen Bildungspolitik werden nunmehr Kompetenzen und Fähigkeiten bestimmt, die als Voraussetzung für eine Teilhabe im digitalen Raum gelten. Institutionell-angeleitete Beteiligungspraktiken, die von Schüler*innen im Fach Medienbildung erlernt werden sollen, schließen die vielfältigen digitalen Beteiligungsprozesse, die Jugendliche bereits selbstständig gestalten, nicht mit ein. Der vorliegende Artikel diskutiert die Komplexität und Heterogenität digitaler Partizipation und zeigt, wie Jugendliche im institutionellen Raum und durch ihre individuelle und soziale Nutzung digitaler Medien jeweils einen Bildungsanteil bezüglich digitaler Beteiligung entwickeln. Dabei werden die Jugendlichen über ihre Rolle als Schüler*in hinaus als bereits partizipierende Subjekte sichtbar gemacht, und nicht-institutionelle Beteiligungspraktiken werden als konstitutiver Teil des Lernprozesses von digitaler Partizipation diskutiert.
Beteiligt euch! Kulturanthropologische Perspektiven auf einen Imperativ der Gegenwart
Authors: Klausner Martina
Published: April 2023

Die Aufforderung sich zu beteiligen sowie die Forderung beteiligt zu werden ist mittlerweile in vielen gesellschaftlichen Bereichen allgegenwärtig und zu einem Imperativ der Gegenwart geworden. Menschen fordern, dass ihre Sichtweise, ihre Expertise in Entscheidungsprozessen berücksichtigt wird oder werden aufgefordert sich in entsprechende Gestaltungsprozesse einzubringen. Was es dabei in der Praxis bedeutet, sich zu beteiligen, kann unterschiedlichen Formen einnehmen und unterschiedliche Erfahrungen produzieren. Die vier Beiträge in diesem Band, die im Rahmen eines Lehrforschungsprojektes am Institut für Kulturanthropologie und Europäische Ethnologie entstanden sind, stellen vier solcher Beteiligungsprozesse vor.  Sie nehmen uns mit zu einem feministischen Kollektiv in Uruguay, auf den Schulhof, in ein klinisches Forschungsprojekt und ins Museum. Eng an den Erfahrungen derjenigen, die sich beteiligen, arbeiten sie heraus, was Beteiligung ermöglicht, aber auch Grenzen setzt und wie die Akteur:innen mit den entstehenden Spannungsverhältnissen umgehen. In der Einleitung zum Band werden kulturanthropologische Ansätze zur Erforschung und Analyse von Beteiligung eingeführt sowie die vier Beiträge des Bandes vorgestellt.

Urea is the standard source of nitrogen for plants, yet it is very unstable, causing losses and environmental pollution. The objective of this study is to validate the technology of spraying liquid source N-Top® of nitrogen for foliar uptake, considering the main oat crops systems in southern Brazil under different agricultural year conditions. The study was developed in 2016, 2017, and 2018, in the city of Augusto Pestana, RS, Brazil, in system soybean/oat and maize/oat. In each system, two experiments were conducted, one for quantifying the biomass rate and the other for the estimation of grain yield. In the four experiments, the design of the randomized block was used with four repetitions in factorial 2×4, for 2 nitrogen sources (liquid and urea) with 4 doses of the nutrient (0, 30, 60, and 120 kg ha-1), respectively. The urea source with 45% of nitrogen for root absorption and the liquid with 28% (N-Top®), via foliar absorption, were applied at the phenological stage of the fourth expanded leaf. In corn/oat system, increasing the dose of nitrogen from urea and liquid sources promotes linear behavior in the expression of grain yield, with similar values of angular coefficient. In the soybean/oat system in the average of the agricultural years, the dose of 78 kg ha-1 of nitrogen, promotes grain yield around 3000 kg ha-1, regardless of the nutrient source. N-top® liquid source nitrogen validation is confirmed, however the acquisition cost may make the recommendation unfeasible

The sour passion fruit is an allogamous species which presents high genetic variability. It is being propagated commercially via seeds. The propagation of species through seeds can be affected by several factors such as the thermal amplitude throughout the day during the germination and the genetic characteristics of the individual. The objective of this study was to evaluate the germination and vigor of seedlings of genotypes of sour passion fruit under different thermal amplitudes of the air. The experiment was conducted in a germination chamber. The factorial scheme was 5 × 3, referring to the five thermal amplitudes of the air (25.0; 22.5-27.5; 20.0-30.0; 17.5-32.5 and 15.0-35.0 ° C) and three genotypes of sour passion fruit (BRS SC1, BRS GA1 and FB-200) in a completely randomized design with six replicates of 25 seeds per plot. The variables analyzed were percentage of velocity index, mean time of emergence, total length, shoot and root and dry mass of seedlings. The thermal amplitude close to 20.0-30.0 °C favored the emergence and vigor of sour passion fruit genotypes. The germination process and the biometric growth of the passion fruit seedlings are adversely affected in high thermal air amplitudes

Continued evaluation for drought tolerance on crops with high potential is an important factor in mitigating the effects of climate change and in the long run secure enough food and alleviate world hunger. Sweet sorghum is one of the multifunctional crops which has shown potential as food, industrial and bioenergy source, thus it is important to study its potential under various conditions. A pot study was conducted in early rainy season (March-August 2020), the experiment was arranged 3 × 2 factorial in RCBD with four replications. Factor A was 3 water regimes (FC, 2/3AW and 1/3AW), factor B was two sweet sorghum cultivars [cv. Suwan Sweet Extra (Thai sweet sorghum) and SSV74 (imported from India)]. The results revealed that significant differences were not observed among water regimes in most traits i.e. plant height, stalk diameter, relative water content (RWC), stalk fresh weight and juice yield in harvesting day. This could suggest that sweet sorghum will perform well in any moisture condition, most importantly in lesser moisture environments. Significant differences were observed among sweet sorghum cultivars in several traits i.e. spad chlorophyll meter reading (SCMR), chlorophyll content, brix value, root dry weight, juice yield and R/S ration at harvesting day. Relationship among traits were also observed but the most interesting results was where we found juice yield having negative correlation to brix value (r=-0.736***) and another no correlation was observed between stalk weight and juice

Poor management of water sources is one of the major challenge for developing nations to provide safe water to increasing population. The Central Ground Water Board, India 2019 reports that all 13 zones of Jaipur city are in the dark zone. Dark zones are those area where the ground water exploitation is extremely high and are notified for protection by the State Government. With a population of 4.1 million, Jaipur city has a water demand deficit of around 125 MLD with dependence on ground water is increasing tremendously. The city's water table has gone down 25 metres in the last decade. Higher concentrations of fluoride, nitrate, and total dissolved solids, is a common problem in the city's ground water. Presently the city gets its water from Bisalpur dam which is 120 km away, proved to be a very costly arrangement. This paper analyses the various contaminants present in ground water. A detailed survey and data collection was done, which was further analysed through GIS spatial distribution, predicting the concentration in all 91 wards of the city. Results show that some wards are at a critical point in terms of deteriorating water quality to be addressed by city planners and urban local bodies.

Stormwater harvesting via managed aquifer recharge in retrofitted infrastructure has been posited as a method for resource augmentation in Cape Town. However, the existing guidelines on stormwater retrofits are technically inclined, occidental, and generally misaligned with the realities and socio-economic contexts of developing nations like South Africa. Water and urban practitioners from developing nations cannot just 'copy and paste' existing guidelines as different socio-economic dimensions and colonial histories typically hinder 'traditional' approaches. This paper assesses how a transdisciplinary team navigated these realities in a case study of a retrofitted pond in Mitchells Plain, Cape Town. A decolonial thinking framework was applied for reflection and thematic content analysis. The framework was used to unpack how the team encountered, addressed, and learned from the challenges during the retrofit process. The research team found that the retrofit process within a context of under-resourced South African communities can be viewed as developmental work with a strong emphasis on continuous community engagement. Thus, it is suggested that in the South African context, water practitioners should consider, at the fore, interaction with local communities, including awareness of racialised histories, to ensure projects are successfully implemented and completed.
